Turbulence Kinetic Energy in the Oklahoma City Urban Environment  

SciTech Connect

The Joint URBAN 2003 field experiment took place in Oklahoma City, Oklahoma, during July 2003 to explore the effect of an urban canopy on the transport and diffusion of a passive tracer released in an urban area. Over one hundred three-dimensional sonic anemometers were deployed in and around the urban area to monitor wind speed, direction, and turbulence during releases of SF6. Deployment locations include a profile of eight sonic anemometers mounted on a crane located 1 km north (typically downwind) of the central business district, and several surface meteorological towers within an urban canyon.

Diurnal cycle of the Oklahoma City urban heat island  

NASA Astrophysics Data System (ADS)

Between the dates of 28 June and 31 July 2003, the Joint Urban 2003 (JU2003) field project was conducted in Oklahoma City and was the largest urban dispersion experiment ever in North America. Because the focus of JU2003 was on atmospheric processes within the urban environment, an extremely dense network of instrumentation was deployed in and around the central business district (CBD) both prior to and during the field experiment. Among the variables collected were high-resolution observations of air temperature from various instrument sources. Additional observations of air temperature were also collected at Oklahoma Mesonet stations in the rural areas surrounding Oklahoma City. Using an index value, the diurnal cycle of the urban heat island (UHI) for Oklahoma City, with respect to the surrounding rural terrain, was quantified. The results revealed a consistent mean nocturnal UHI greater than 1.5°C at both 2 and 9 m. However, observations at 2 m during JU2003 revealed a significant urban "cool" island during the convective portion of the day. The mean variability of temperature within the urban core of Oklahoma City increased significantly after sunrise, increased to a maximum near solar noon, and decreased following sunset. These results were inconsistent with the rural observations wherein the variability among sites was maximized during the nocturnal period. Finally, the vertical temperature gradient between 2 and 9 m demonstrated a clear and strong diurnal trend at the rural locations, whereas observations from the urban environment were nearly isothermal and consistent with near-neutral conditions throughout JU2003.

Turbulent Kinetic Energy in the Oklahoma City Urban Environment  

SciTech Connect

A major field experiment, Joint URBAN 2003 (JU2003), was conducted in Oklahoma City in July 2003 to collect meteorological and tracer data sets for evaluating dispersion models in urban areas. The Department of Homeland Security and the Defense Threat Reduction Agency were the primary sponsors of JU2003. Investigators from five Department of Energy national laboratories, several other government agencies, universities, private companies, and international agencies conducted the experiment. Observations to characterize the meteorology in and around the urban area complemented the observation of the dispersion of SF6, an inert tracer gas. Over one hundred threedimensional sonic anemometers were deployed in and around the urban area to monitor wind speed, direction, and turbulence fluxes during releases of SF6. Sonic deployment locations included a profile of eight sonic anemometers mounted on a crane less than 1 km north of the central business district (CBD). Using data from these and other sonic anemometers deployed in the urban area, we can quantify the effect of the urban area on atmospheric turbulence and compare results seen in OKC to those in other urban areas to assess the parameters typically used in parameterizations of urban turbulence.

Estimated flood peak discharges on Twin, Brock, and Lightning creeks, Southwest Oklahoma City, Oklahoma, May 8, 1993  

USGS Publications Warehouse

The flash flood in southwestern Oklahoma City, Oklahoma, May 8, 1993, was the result of an intense 3-hour rainfall on saturated ground or impervious surfaces. The total precipitation of 5.28 inches was close to the 3-hour, 100-year frequency and produced extensive flooding. The most serious flooding was on Twin, Brock, and Lightning Creeks. Four people died in this flood. Over 1,900 structures were damaged along the 3 creeks. There were about $3 million in damages to Oklahoma City public facilities, the majority of which were in the three basins. A study was conducted to determine the magnitude of the May 8, 1993, flood peak discharge in these three creeks in southwestern Oklahoma City and compare these peaks with published flood estimates. Flood peak-discharge estimates for these creeks were determined at 11 study sites using a step-backwater analysis to match the flood water-surface profiles defined by high-water marks. The unit discharges during peak runoff ranged from 881 cubic feet per second per square mile for Lightning Creek at SW 44th Street to 3,570 cubic feet per second per square mile for Brock Creek at SW 59th Street. The ratios of the 1993 flood peak discharges to the Federal Emergency Management Agency 100-year flood peak discharges ranged from 1.25 to 3.29. The water-surface elevations ranged from 0.2 foot to 5.9 feet above the Federal Emergency Management Agency 500-year flood water-surface elevations. The very large flood peaks in these 3 small urban basins were the result of very intense rainfall in a short period of time, close to 100 percent runoff due to ground surfaces being essentially impervious, and the city streets acting as efficient conveyances to the main channels. The unit discharges compare in magnitude to other extraordinary Oklahoma urban floods.

Statistical analysis of stream water-quality data and sampling network design near Oklahoma City, central Oklahoma, 1977-1999  

USGS Publications Warehouse

Water-quality data collected from 1993-99 at five sites on Bluff, Deer, and Chisholm Creeks and from 1988-99 at five sites in the North Canadian River indicated that there were significant differences in constituent values among sites for water properties, major ions, trace elements, nutrients, turbidity, pesticides, and bacteria. Concentrations of dissolved solids and sulfate generally decreased as streams flowed through the Oklahoma City urban area. Concentrations of organic carbon, nitrogen and phosphorus compounds, lindane, and 2,4-D, and frequencies of detection of pesticides increased in the North Canadian River as it flowed through the urban area. Volatile organic compounds were not detected in samples collected quarterly from 1988-90 at sites on the North Canadian River. Concentrations of some compounds, including dissolved oxygen, sulfate, chloride, ammonia, manganese, diazinon, dieldrin, and fecal coliform bacteria periodically exceeded Federal or state water-quality standards at some sites. Regression analyses were used to identify trends in constituent concentrations related to streamflow, season, and time. Trends for some constituents were indicated at all sites, but most trends were site-specific. Seasonal trends were evident for several constituents: suspended solids, organic nitrogen, and biochemical oxygen demand were greatest during summer. Dissolved oxygen, ammonia, and nitrite plus nitrate-nitrogen were greatest during winter. Concentrations of dissolved oxygen, fluoride, sulfate, total suspended solids, iron, and manganese generally increased with time. Concentrations of chloride, nitrite plus nitrate-nitrogen, dissolved phosphorus, dissolved orthophosphate, biochemical oxygen demand, dieldrin, and lindane decreased with time. There was relatively little change in land use from the late 1970s to the mid-1990s due to relatively modest rates of population growth in the study area during that period. Most changes in water quality in these streams and rivers may be due to changes in chemical use and wastewater treatment practices. The sampling network was evaluated with respect to areal coverage, sampling frequency, and analytical schedules. Areal coverage could be expanded to include one additional watershed that is not part of the current network. A new sampling site on the North Canadian River might be useful because of expanding urbanization west of the city, but sampling at some other sites could be discontinued or reduced based on comparisons of data between the sites. Additional real-time or periodic monitoring for dissolved oxygen may be useful to prevent anoxic conditions in pools behind new low-water dams. The sampling schedules, both monthly and quarterly, are adequate to evaluate trends, but additional sampling during flow extremes may be needed to quantify loads and evaluate water quality during flow extremes. Emerging water-quality issues may require sampling for volatile organic compounds, sulfide, total phosphorus, chlorophyll-a, Escherichia coli, and enterococci, as well as use of more sensitive laboratory analytical methods for determination of cadmium, mercury, lead, and silver.

Final Report for the Joint Urban 2003 Atmospheric Dispersion Study in Oklahoma City: Lawrence Livermore National Laboratory participation  

SciTech Connect

The Joint Urban 2003 (JU2003) field study was designed to collect meteorological and tracer data resolving atmospheric dispersion at scales-of-motion ranging from flows in and around a single city block, in and around several blocks in the downtown Central Business District (CBD), and into the suburban Oklahoma City area a few km from the CBD. Indoor tracer and flow measurements within four downtown study buildings were also made in conjunction with detailed outdoor measurements investigating the outdoor-indoor exchange rates and mechanisms. The movement of tracer within the study buildings was also studied. The data from the field experiment is being used to evaluate models that are being developed for predicting dispersion of contaminants in urban areas. These models may be fast-response models based on semi-empirical algorithms that are used in real-time emergencies, or highly sophisticated computational fluid dynamics models that resolve individual building faces and crevices. The data from the field experiment, together with the models, can then be used to develop other advanced tools that are especially valuable in the efforts to thwart terrorists. These include tools for finding location and characteristics of a contaminant source; tools that can be used for real-time response or for forensic investigation. The tools will make use of monitoring networks for biological agents that are being established in several sensitive cities throughout the nation. This major urban study was conducted beginning June 28 and ending July 31, 2003. It included several integrated scientific components necessary to describe and understand the physical processes governing dispersion within and surrounding an urban area and into and within building environments. The components included characterizing: (1) the urban boundary layer and the development of the urban boundary layer within the atmospheric boundary layer, (2) the flows within and downwind of the tall-building core, (3) the flows within a street canyon including the effects of traffic on turbulence, (4) the surface energy balance within an urban area, (5) the dispersion of tracer into, out of and within buildings, and (6) the dispersion of tracer throughout the tall-building core and out to four km downwind from the release. The scientific elements of the study were accomplished using state-of-the-art meteorological and tracer instruments including lidars, sodars, radars, sonic anemometers, airplane-based meteorological sensors, fast-response tracer analyzers and helicopter-based remote tracer detectors. Winds and other meteorological quantities were measured continuously at nearly 200 locations in and around downtown Oklahoma City. Ten intensive operation periods (IOPs) of 8-hours each were completed during the 34-day study period where detailed meteorological, turbulence and tracer measurements were made. Sulfur hexafluoride tracer was released in downtown Oklahoma City and sampled in and around downtown and as far as four km downwind. During four of the ten IOPs the infiltration of tracer into four downtown buildings was studied with detailed measurements of tracer and flows within and surrounding some buildings. Tracer was sampled using over 200 integrated samplers and 25 fast response analyzers. Vertical measurements of tracer were made by placing samplers on the tops of nearly 20 buildings and by sampling tracer at 7 levels on a 90 m crane. The tracer and meteorological data collected in Oklahoma City is being used to evaluate and improve existing indoor and outdoor dispersion models, including fine-scale computational fluid dynamics (CFD) models, mesoscale numerical weather prediction models with sub-grid scale urban parameterizations and fast-response dispersion models that typically rely on empirical or semi-empirical relationships describing the atmospheric processes. The data will lead to improved algorithms and parameterizations within these models.

Nocturnal Low-Level-Jet-Dominated Atmospheric Boundary Layer Observed by a Doppler Lidar Over Oklahoma City during JU2003  

SciTech Connect

Boundary layer wind data observed by a Doppler lidar and sonic anemometers during the mornings of three intensive observational periods (IOP2, IOP3, and IOP7) of the Joint Urban 2003 (JU2003) field experiment are analyzed to extract the mean and turbulent characteristics of airflow over Oklahoma City, Oklahoma. A strong nocturnal low-level jet (LLJ) dominated the flow in the boundary layer over the measurement domain from midnight to the morning hours. Lidar scans through the LLJ taken after sunrise indicate that the LLJ elevation shows a gradual increase of 25-100 m over the urban area relative to that over the upstream suburban area. The mean wind speed beneath the jet over the urban area is about 10%-15% slower than that over the suburban area. Sonic anemometer observations combined with Doppler lidar observations in the urban and suburban areas are also analyzed to investigate the boundary layer turbulence production in the LLJ-dominated atmospheric boundary layer. The turbulence kinetic energy was higher over the urban domain mainly because of the shear production of building surfaces and building wakes. Direct transport of turbulent momentum flux from the LLJ to the urban street level was very small because of the relatively high elevation of the jet. However, since the LLJ dominated the mean wind in the boundary layer, the turbulence kinetic energy in the urban domain is correlated directly with the LLJ maximum speed and inversely with its height. The results indicate that the jet Richardson number is a reasonably good indicator for turbulent kinetic energy over the urban domain in the LLJ-dominated atmospheric boundary layer.

Autonomic reactivity and hypothalamic pituitary adrenal axis dysregulation in spouses of Oklahoma City bombing survivors 7 years after the attack  

PubMed Central

Objective The objective of this exploratory pilot study was to examine autonomic reactivity and hypothalamic pituitary adrenal axis dysregulation in spouses of highly exposed survivors of the 1995 Oklahoma City bombing. Methods This study compared psychiatric diagnoses and biological stress markers (physiological reactivity and cortisol measures) in spouses of bombing survivors and matched community participants. Spouses were recruited through bombing survivors who participated in prior studies. Individuals with medical illnesses and those taking psychotropic medications that would confound biological stress measures were excluded. The final sample included 15 spouses and 15 community participants. The primary outcome measures were psychiatric diagnoses assessed with the Diagnostic Interview Schedule for DSM-IV (DIS-IV). Biological stress markers were physiological reactivity and recovery in heart rate and blood pressure responses to a trauma interview and cortisol (morning, afternoon, and diurnal variation). Results Compared to the community participants, spouses evidenced greater reactivity in heart rate, systolic blood pressure, and diastolic blood pressure; delayed recovery in systolic blood pressure; and higher afternoon salivary cortisol. Conclusions The results support the need for further research in this area to clarify post-disaster effects on biological stress measures in the spouses of survivors and the potential significance of these effects and to address the needs of this important population which may be overlooked in recovery efforts.

Incident-related television viewing and psychiatric disorders in Oklahoma City bombing survivors.  

PubMed

The objective of this study was to examine terrorism media coverage and psychiatric outcomes in directly-exposed terrorism survivors. The study used (1) self-report questionnaires to retrospectively assess event-related media behaviors and reactions in a cross sectional design and (2) longitudinal structured diagnostic interviews to assess psychopathologic outcomes. The participants were 99 directly-exposed Oklahoma City bombing survivors who were initially studied six months after the 1995 incident. Though a fear reaction to bombing-related television coverage and fear-driven discontinuation of bombing-related media contact were associated with diagnostic outcomes, the number of hours viewing bombing-related television coverage in the first week after the event was not associated with the prevalence of bombing-related posttraumatic stress disorder or post-bombing major depressive disorder during the seven years post event. The results raise doubt about the effects of quantified incident-related television viewing on clinically-significant emotional outcomes in directly-exposed terrorism survivors. PMID:23980489

Computational Fluid Dynamic Simulations of Plume Dispersion in Urban Oklahoma City  

SciTech Connect

A 3D computational fluid dynamics study using Reynolds averaged Navier-Stokes modeling was conducted and validated with field data from the Joint Urban 2003 dispersion study in Oklahoma City. The modeled flow field indicated that the many short buildings in this domain had a relatively small effect on the flow field, while the few tall buildings drove the transport and dispersion of tracer gas through the domain. Modeled concentrations and wind speeds were compared to observations along a vertical profile located about 500 meters downwind of the source. The isothermal base case using the k-epsilon closure model was within 50% of the field measurements, while a convective case with ground and building surfaces 10 degrees C hotter than ambient temperatures improved the modeled profile to within 30% of observations. Varying wind direction and source location had a significant effect on the plume dispersion due to the irregularity of the urban landscape. The location of the tallest obstacle in this domain with respect to the source position defined the size and shape of tracer plumes in this study. Model results based upon a Reynolds stress closure scheme were also compared to the vertical concentration profiles. For this location, the isothermal case underestimated concentrations; however, the case with thermal buoyancy resulted in concentrations within 25% of the observations.

Hydrogeology and simulation of groundwater flow in the Central Oklahoma (Garber-Wellington) Aquifer, Oklahoma, 1987 to 2009, and simulation of available water in storage, 2010-2059  

USGS Publications Warehouse

The Central Oklahoma (Garber-Wellington) aquifer underlies about 3,000 square miles of central Oklahoma. The study area for this investigation was the extent of the Central Oklahoma aquifer. Water from the Central Oklahoma aquifer is used for public, industrial, commercial, agricultural, and domestic supply. With the exception of Oklahoma City, all of the major communities in central Oklahoma rely either solely or partly on groundwater from this aquifer. The Oklahoma City metropolitan area, incorporating parts of Canadian, Cleveland, Grady, Lincoln, Logan, McClain, and Oklahoma Counties, has a population of approximately 1.2 million people. As areas are developed for groundwater supply, increased groundwater withdrawals may result in decreases in long-term aquifer storage. The U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, investigated the hydrogeology and simulated groundwater flow in the aquifer using a numerical groundwater-flow model. The purpose of this report is to describe an investigation of the Central Oklahoma aquifer that included analyses of the hydrogeology, hydrogeologic framework of the aquifer, and construction of a numerical groundwater-flow model. The groundwater-flow model was used to simulate groundwater levels and for water-budget analysis. A calibrated transient model was used to evaluate changes in groundwater storage associated with increased future water demands.

Chemical analyses of water samples from the Picher mining area, northeast Oklahoma and southeast Kansas  

USGS Publications Warehouse

Chemical analyses are presented for 169 water samples from Tar Creek drainage and the Picher lead-zinc mining area of northeast Oklahoma and southeast Kansas. Water samples were taken from November 1983 through February 1986 from the abandoned mines, from points of mine-water discharge, and from surface-water locations upstream and downstream from mine discharge area. The pH, temperature, alkalinity, dissolved oxygen, and specific conductance were measured in the field. Laboratory analyses routinely included the major ions plus aluminum, cadmium, copper, iron, lead, manganese, nickel, and zinc. Non-routine analyses of dissolved gases and tritium are presented. Stable carbon-isotope ratios for 11 mine-water samples and three carbonate-rock samples are reported. Miscellaneous stream-discharge measurements made at the time of sampling or taken from gaging-station records are included in the report.

Reductive Dechlorination of Chlorinated Ethenes Under Oxidation-Reduction Conditions and Potentiometric Surfaces in Two Trichloroethene-Contaminated Zones at the Double Eagle and Fourth Street Superfund Sites in Oklahoma City, Oklahoma  

USGS Publications Warehouse

The Double Eagle Refining Superfund site and the Fourth Street Abandoned Refinery Superfund site are in northeast Oklahoma City, Oklahoma, adjacent to one another. The Double Eagle facility became a Superfund site on the basis of contamination from lead and volatile organic compounds; the Fourth Street facility on the basis of volatile organic compounds, pesticides, and acid-base neutral compounds. The study documented in this report was done to investigate whether reductive dechlorination of chlorinated ethenes under oxidation-reduction conditions is occurring in two zones of the Garber-Wellington aquifer (shallow zone 30?60 to 75 feet below land surface, deep zone 75 to 160 feet below land surface) at the sites; and to construct potentiometric surfaces of the two water-yielding zones to determine the directions of ground-water flow at the sites. The presence in some wells of intermediate products of reductive dechlorination, dichloroethene and vinyl chloride, is an indication that reductive dechlorination of trichloroethene is occurring. Dissolved oxygen concentrations (less than 0.5 milligram per liter) indicate that consumption of dissolved oxygen likely had occurred in the oxygen-reducing microbial process associated with reductive dechlorination. Concentrations of nitrate and nitrite nitrogen (generally less than 2.0 and 0.06 milligrams per liter, respectively) indicate that nitrate reduction probably is not a key process in either aquifer zone. Concentrations of ferrous iron greater than 1.00 milligram per liter in the majority of wells sampled indicate that iron reduction is probable. Concentrations of sulfide less than 0.05 milligram per liter in all wells indicate that sulfate reduction probably is not a key process in either zone. The presence of methane in ground water is an indication of strongly reducing conditions that facilitate reductive dechlorination. Methane was detected in all but one well. In the shallow zone in the eastern part of the study area, ground water flowing from the northwest and south coalesces in a potentiometric trough, then moves westward and ultimately northwestward. In the western part of the study area, ground water in the shallow zone flows northwest. In the deep zone in the eastern part of the study area, ground water generally flows northwestward; and in the western part of the study area, ground water in the deep zone generally flows northward.

Assessment of Local Recharge Area Characteristics of Four Caves in Northern Arkansas and Northeastern Oklahoma, 2004-07  

USGS Publications Warehouse

A study was conducted from 2004 to 2007 by the U.S. Geological Survey in cooperation with the U.S. Fish and Wildlife Service to assess the characteristics of the local recharge areas of four caves in northern Arkansas and northeastern Oklahoma that provide habitat for a number of unique organisms. Characterization of the local recharge areas are important because the caves occur in a predominately karst system and because land use proximal to the caves, including areas suspected to lie within the local recharge areas, may include activities with potentially deleterious effects to cave water quality. An integrated approach was used to determine the hydrogeologic characteristics and the extent of the local recharge areas of Civil War Cave, January-Stansbury Cave, Nesbitt Spring Cave, and Wasson's Mud Cave. This approach incorporated methods of hydrology, structural geology, geomorphology, and geochemistry. Continuous water-level and water-temperature data were collected at each cave for various periods to determine recharge characteristics. Field investigations were conducted to determine surficial controls affecting the groundwater flow and connections of the groundwater system to land-surface processes in each study area. Qualitative groundwater tracing also was conducted at each cave to help define the local recharge areas. These independent methods of investigation provided multiple lines of evidence for effectively describing the behavior of these complex hydrologic systems. Civil War Cave is located near the city of Bentonville in Benton County, Arkansas, and provides habitat for the Ozark cavefish. Civil War Cave is developed entirely within the epikarst of the upper Boone Formation, and recharge to Civil War Cave occurs from the Boone Formation (Springfield Plateau aquifer). The daily mean discharge for the period of study was 0.59 cubic feet per second and ranged from 0.19 to 2.8 cubic feet per second. The mean water temperature for Civil War Cave was 14.0 degrees Celsius. The calculated recharge area for Civil War Cave ranged from 0.13 to 2.5 square miles using the water-balance equation to 3.80 square miles using a normalized base-flow method. Tracer tests indicated a portion of the water within Civil War Cave was from across a major topographic divide located to the southwest. January-Stansbury Cave is located in Delaware County in northeastern Oklahoma, and provides habitat for the Oklahoma cave crayfish and the Ozark cavefish. January-Stansbury Cave is developed in the St. Joe Limestone member of the Boone Formation. The daily mean discharge for the period of study was 1.0 cubic foot per second and ranged from 0.35 to 8.7 cubic feet per second. The mean water temperature for January-Stansbury Cave was 14.3 degrees. The calculated recharge area for January-Stansbury Cave using the water-balance equation ranged from approximately 0.04 to 0.83 square miles. Tracer tests generally showed water discharging from January-Stansbury Cave during high flow originates from within the topographic drainage area and from an area outside the topographic drainage area to the southwest. Nesbitt Spring Cave is located near the city of Mountain View in north-central Arkansas and provides habitat for the Hell Creek cave crayfish. Nesbitt Spring Cave is developed in the Plattin Limestone (Ozark aquifer) and is recharged through the Boone Formation (Springfield Plateau aquifer). The mean daily discharge for the period of study was 4.5 cubic feet per second and ranged from 0.39 to 70.7 cubic feet per second. The mean water temperature for Nesbitt Spring Cave was 14.2 degrees Celsius. The calculated recharge area for Nesbitt Spring Cave using the water-balance equation ranged from 0.49 square mile to 4.0 square miles. Tracer tests generally showed a portion of water discharging from Nesbitt Spring during high flow originates from outside the topographic drainage area. Wasson's Mud Cave is located near the city of Springtown

Gaseous Oxidized Mercury Dry Deposition Measurements in the Southwestern USA: A Comparison between Texas, Eastern Oklahoma, and the Four Corners Area  

PubMed Central

Gaseous oxidized mercury (GOM) dry deposition measurements using aerodynamic surrogate surface passive samplers were collected in central and eastern Texas and eastern Oklahoma, from September 2011 to September 2012. The purpose of this study was to provide an initial characterization of the magnitude and spatial extent of ambient GOM dry deposition in central and eastern Texas for a 12-month period which contained statistically average annual results for precipitation totals, temperature, and wind speed. The research objective was to investigate GOM dry deposition in areas of Texas impacted by emissions from coal-fired utility boilers and compare it with GOM dry deposition measurements previously observed in eastern Oklahoma and the Four Corners area. Annual GOM dry deposition rate estimates were relatively low in Texas, ranging from 0.1 to 0.3?ng/m2h at the four Texas monitoring sites, similar to the 0.2?ng/m2h annual GOM dry deposition rate estimate recorded at the eastern Oklahoma monitoring site. The Texas and eastern Oklahoma annual GOM dry deposition rate estimates were at least four times lower than the highest annual GOM dry deposition rate estimate previously measured in the more arid bordering western states of New Mexico and Colorado in the Four Corners area.

Variability of Ambient Aerosol in the Mexico City Metropolian Area  

NASA Astrophysics Data System (ADS)

The spatial and temporal variations of the ambient aerosol in the Mexico City Metropolitan area was characterized during the springs of 2002 and 2003 using a mobile laboratory equipped with gas and particulate measurement instrumentation. The laboratory was operated at various fixed sites locations in and at the edge of the metropolitan area (Xalostoc, Merced, Cenica, Pedregal, and Santa Ana). Size-resolved aerosol mass and chemical composition was measured with an aerosol mass spectrometer and selected trace gas species (low mass organic compounds, NO, NO2, NOy, O3, SO2, CH2O, NH3, CO2) were measured using a proton transfer reaction mass spectrometer and various optical systems. The aerosol was predominantly organic in composition with lesser amounts of ammonium nitrate, sulfate, and chloride. The organic component was composed of mixed primary and secondary organic compounds. The mass loading and chemical composition of the aerosol was influenced by local and regional air pollution sources and the meteorology in Mexico City. Most urban sites were influenced by a strong diurnal particulate mass trend indicative of primary organic emissions from traffic during early morning and subsequently oxidized/processed organics and ammonium nitrate particles starting in the mid-morning (~9 AM) and continuing throughout the day. Morning traffic-related primary organic emissions were strongest at La Merced (center of Mexico City, located near a busy food market), more subdued at other fixed sites further from the city center, and varied depending upon the day of week and holiday schedules. Particle-bound polycyclic aromatic hydrocarbons were observed within Mexico City fixed sites and were correlated with traffic organic PM emissions. Oxidized organic and ammonium nitrate events occurred during mid-morning at all city sites and were well correlated with gas phase photochemical activity. The daily ammonium nitrate aerosol event occurred later at sites near the city limits, likely due to transported emissions from the city center. The sulfate particulate mass measured throughout most of the Mexico City area did not show a consistent diurnal pattern, characteristic of aged regional aerosol. Local refuse burns were observed to be a source of inorganic particulate chloride.

Development and Application to Oklahoma City of a New Mass, Energy, Vorticity, and Potential Enstrophy Conserving Scheme for 3D Nonhydrostatic Atmospheric Flows with Complex Boundaries  

NASA Astrophysics Data System (ADS)

We present a generalization of a mass, energy, vorticity, and potential enstrophy conserving numerical scheme for the 2D shallow water equations (SWEs) in domains with rigid boundaries (e.g. islands) to the governing equations for 3D nonhydrostatic atmospheric flows expressed in the altitude coordinate (as opposed to a terrain-following vertical coordinate). The scheme for the 2D SWEs consists of the scheme of Arakawa and Lamb (1981) (AL81) away from boundaries and the boundary scheme of Ketefian and Jacobson (2009) (KJ09) at boundaries. We generalize the combined AL81/KJ09 scheme to 3D atmospheric flows with rigid boundaries (e.g. hills and buildings) in such a way that, like the continuous equations governing these flows, the generalized 3D scheme conserves mass, energy, vorticity, and potential enstrophy in the special case of 2D barotropic flow. We perform 2D numerical simulations in a vertical plane to demonstrate the scheme's conservation properties. We also perform 3D simulations of flows in a domain with building-scale topography from Oklahoma City, and we use the velocity fields from these simulations to model the transport of an inert tracer around this topography. The generalized 3D scheme is useful because it conserves several important domain-summed quantities in atmospheric models that use the altitude coordinate, thereby avoiding the large errors in pressure-gradient calculations often found in models that use a terrain-following vertical coordinate.

Hydrology and Water Quality near Bromide Pavilion in Chickasaw National Recreation Area, Murray County, Oklahoma, 2000  

USGS Publications Warehouse

The Bromide Pavilion in Chickasaw National Recreation Area drew many thousands of people annually to drink the mineral-rich waters piped from nearby Bromide and Medicine Springs. Periodic detection of fecal coliform bacteria in water piped to the pavilion from the springs, low yields of the springs, or flooding by adjacent Rock Creek prompted National Park Service officials to discontinue piping of the springs to the pavilion in the 1970s. Park officials would like to resume piping mineralized spring water to the pavilion to restore it as a visitor attraction, but they are concerned about the ability of the springs to provide sufficient quantities of potable water. Pumping and sampling of Bromide and Medicine Springs and Rock Creek six times during 2000 indicate that these springs may not provide sufficient water for Bromide Pavilion to supply large numbers of visitors. A potential problem with piping water from Medicine Spring is the presence of an undercut, overhanging cliff composed of conglomerate, which may collapse. Evidence of intermittent inundation of the springs by Rock Creek and seepage of surface water into the spring vaults from the adjoining creek pose a threat of contamination of the springs. Escherichia coli, fecal coliform, and fecal streptococcal bacteria were detected in some samples from the springs, indicating possible fecal contamination. Cysts of Giardia lamblia and oocysts of Cryptosporidium parvum protozoa were not detected in the creek or the springs. Total culturable enteric viruses were detected in only one water sample taken from Rock Creek.

Analysis of environmental setting, surface-water and groundwater data, and data gaps for the Citizen Potawatomi Nation Tribal Jurisdictional Area, Oklahoma, through 2011  

USGS Publications Warehouse

The Citizen Potawatomi Nation Tribal Jurisdictional Area, consisting of approximately 960 square miles in parts of three counties in central Oklahoma, has an abundance of water resources, being underlain by three principal aquifers (alluvial/terrace, Central Oklahoma, and Vamoosa-Ada), bordered by two major rivers (North Canadian and Canadian), and has several smaller drainages. The Central Oklahoma aquifer (also referred to as the Garber-Wellington aquifer) underlies approximately 3,000 square miles in central Oklahoma in parts of Cleveland, Logan, Lincoln, Oklahoma, and Pottawatomie Counties and much of the tribal jurisdictional area. Water from these aquifers is used for municipal, industrial, commercial, agricultural, and domestic supplies. The approximately 115,000 people living in this area used an estimated 4.41 million gallons of fresh groundwater, 12.12 million gallons of fresh surface water, and 8.15 million gallons of saline groundwater per day in 2005. Approximately 8.48, 2.65, 2.24, 1.55, 0.83, and 0.81 million gallons per day of that water were used for domestic, livestock, commercial, industrial, crop irrigation, and thermoelectric purposes, respectively. Approximately one-third of the water used in 2005 was saline water produced during petroleum production. Future changes in use of freshwater in this area will be affected primarily by changes in population and agricultural practices. Future changes in saline water use will be affected substantially by changes in petroleum production. Parts of the area periodically are subject to flooding and severe droughts that can limit available water resources, particularly during summers, when water use increases and streamflows substantially decrease. Most of the area is characterized by rural types of land cover such as grassland, pasture/hay fields, and deciduous forest, which may limit negative effects on water quality by human activities because of lesser emissions of man-made chemicals on such areas than in more urbanized areas. Much of the water in the area is of good quality, though some parts of this area have water quality impaired by very hard surface water and groundwater; large chloride concentrations in some smaller streams; relatively large concentrations of nutrients and counts of fecal-indicator bacteria in the North Canadian River; and chloride, iron, manganese, and uranium concentrations that exceed primary or secondary drinking-water standards in water samples collected from small numbers of wells. Substantial amounts of hydrologic and water-quality data have been collected in much of this area, but there are gaps in those data caused by relatively few streamflow-gaging stations, uneven distribution of surface-water quality sampling sites, lack of surface-water quality sampling at high-flow and low-flow conditions, and lack of a regularly measured and sampled groundwater network. This report summarizes existing water-use, climatic, geographic, hydrologic, and water-quality data and describes several means of filling gaps in hydrologic data for this area.

Upscaling pollutant dispersion in the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

Pollutant emission is an important problem in megacities such as Mexico City, imposing serious threats to human health and economic activity. Public policies oriented to deal with pollutant management ought to be based upon a close understanding of the transport mechanisms involved in the commonly complex network of streets and buildings. Modeling and simulation tools have proved to be useful for understanding field measurements and developing efficient monitoring strategies. The aim of this work is to provide estimations of the (longitudinal and transverse) dispersion coefficients in upscaled models for pollutant transport in the Mexico City Metropolitan Area (MCMA). To this end, we use the method of volume averaging, which allows calculation of the dispersion coefficients by solving the associated closure problems in some representative regions of the MCMA. The results show that local geometry has an important effect upon contaminant dispersion, especially in the direction that is transverse to the pressure gradient. This suggests that, although winds can remove an important amount of atmospheric contaminants, high transversal dispersion can help in a fast spreading of contaminants within the street network.

A micrometeorological data base for the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

In order to overcome the lack of the surface micrometeorological data required for air quality studies in the Mexico City Metropolitan Area (MCMA), a long-term micrometeorological campaign was carried out in this area along the 2001-year. Three micrometeorological surface stations were installed at sites located at north, north-east, and south sectors of the MCMA. Each station was equipped with a 3D ultrasonic turbulence sensor and with conventional meteorological sensors for temperature, relative humidity, pressure, global radiation, net radiation, and rain. The sampling rates were 10 Hz for the ultrasonic sensor, and 1 Hz for the conventional sensors. One-hour averages were calculated for all the meteorological parameters and for the turbulence parameters such as friction velocity, scale temperature, Monin-Obukhov length, sensible heat flux and turbulent kinetic energy, among others. A simple micrometeorological database was prepared and mounted on a free access Internet page to furnish a specialized tool to the local Authorities to be utilized in health prevention and pollution regulation applications.

Heat flow in Oklahoma  

SciTech Connect

Oklahoma is one area in which terrestrial heat flow data are sparse. The thermal state of the southern mid-continent, however, is a key to understanding several important geologic problems. These include thermal anomalies associated with Paleozoic fluid migrations and the formation of Mississippi Valley-type lead-zinc deposits, the thermal evolution of the Arkoma and Anadarko sedimentary basins, and the history of hydrocarbon generation and overpressuring in the Anadarko Basin. In the late 1920s, the American Petroleum Institute made a set of equilibrium temperature logs in idle oil wells. These temperature data are generally regarded as being high quality, accurate estimates of rock temperature and they cover the entire central part of Oklahoma. Average thermal gradients in the API survey range from 14 to 43 [sup 0]C/km (average 31.2 [sup 0]C/km) over depth intervals that extend from the surface to a an average depth of 961 m. Geothermal gradients decrease from NNE to SSW. The observed change in thermal gradients could be due to a number of factors. The change in thermal gradients could simply reflect changes in lithology and thermal conductivity. Alternatively, the variation in thermal gradients could be indicative of a change in heat flow related perhaps to variations in the concentration of radioactive heat-producing elements in the crust or heat transport by one or more regional groundwater flow systems. We are proceeding to reduce ambiguity in interpretation by estimating heat flow from thermal conductivity measurements on drill cuttings and heat production from available gamma-ray logs which penetrate basement rocks.

Epidemiology of tuberculosis in big cities of the European Union and European Economic Area countries.  

PubMed

This cross-sectional survey aimed to examine the epidemiology of tuberculosis (TB) in European Union (EU) and European Economic Area (EEA) cities with populations greater than 500,000. National TB programme managers were asked to provide data on big city population size, total number of notified TB cases in big cities and national notification rate for 2009. A rate ratio was calculated using the big city TB notification rate as a numerator and country TB notification rate, excluding big city TB cases and population, as a denominator. Twenty of the 30 EU/EEA countries had at least one big city. Pooled rate ratios were 2.5, 1.0, and 0.7 in low-, intermediate- and high-incidence countries respectively. In 15 big cities, all in low-incidence countries, rate ratios were twice the national notification rate. These data illustrate the TB epidemiology transition, a situation whereby TB disease concentrates in big cities as national incidence falls, most likely as a result of the higher concentration of risk groups found there. This situation requires targeted interventions and we recommend that big city TB data, including information about patients' risk factors, are collected and analysed systematically, and that successful interventions are shared.

Social differences in avoidable mortality between small areas of 15 European cities: an ecological study  

PubMed Central

Background Health and inequalities in health among inhabitants of European cities are of major importance for European public health and there is great interest in how different health care systems in Europe perform in the reduction of health inequalities. However, evidence on the spatial distribution of cause-specific mortality across neighbourhoods of European cities is scarce. This study presents maps of avoidable mortality in European cities and analyses differences in avoidable mortality between neighbourhoods with different levels of deprivation. Methods We determined the level of mortality from 14 avoidable causes of death for each neighbourhood of 15 large cities in different European regions. To address the problems associated with Standardised Mortality Ratios for small areas we smooth them using the Bayesian model proposed by Besag, York and Mollié. Ecological regression analysis was used to assess the association between social deprivation and mortality. Results Mortality from avoidable causes of death is higher in deprived neighbourhoods and mortality rate ratios between areas with different levels of deprivation differ between gender and cities. In most cases rate ratios are lower among women. While Eastern and Southern European cities show higher levels of avoidable mortality, the association of mortality with social deprivation tends to be higher in Northern and lower in Southern Europe. Conclusions There are marked differences in the level of avoidable mortality between neighbourhoods of European cities and the level of avoidable mortality is associated with social deprivation. There is no systematic difference in the magnitude of this association between European cities or regions. Spatial patterns of avoidable mortality across small city areas can point to possible local problems and specific strategies to reduce health inequality which is important for the development of urban areas and the well-being of their inhabitants.

Trends in socioeconomic inequalities in amenable mortality in urban areas of Spanish cities, 1996-2007  

PubMed Central

Background While research continues into indicators such as preventable and amenable mortality in order to evaluate quality, access, and equity in the healthcare, it is also necessary to continue identifying the areas of greatest risk owing to these causes of death in urban areas of large cities, where a large part of the population is concentrated, in order to carry out specific actions and reduce inequalities in mortality. This study describes inequalities in amenable mortality in relation to socioeconomic status in small urban areas, and analyses their evolution over the course of the periods 1996–99, 2000–2003 and 2004–2007 in three major cities in the Spanish Mediterranean coast (Alicante, Castellón, and Valencia). Methods All deaths attributed to amenable causes were analysed among non-institutionalised residents in the three cities studied over the course of the study periods. Census tracts for the cities were grouped into 3 socioeconomic status levels, from higher to lower levels of deprivation, using 5 indicators obtained from the 2001 Spanish Population Census. For each city, the relative risks of death were estimated between socioeconomic status levels using Poisson’s Regression models, adjusted for age and study period, and distinguishing between genders. Results Amenable mortality contributes significantly to general mortality (around 10%, higher among men), having decreased over time in the three cities studied for men and women. In the three cities studied, with a high degree of consistency, it has been seen that the risks of mortality are greater in areas of higher deprivation, and that these excesses have not significantly modified over time. Conclusions Although amenable mortality decreases over the time period studied, the socioeconomic inequalities observed are maintained in the three cities. Areas have been identified that display excesses in amenable mortality, potentially attributable to differences in the healthcare system, associated with areas of greater deprivation. Action must be taken in these areas of greater inequality in order to reduce the health inequalities detected. The causes behind socioeconomic inequalities in amenable mortality must be studied in depth. PMID:24690471

Hydrogeological aspects of groundwater drainage of the urban areas in Kuwait City  

NASA Astrophysics Data System (ADS)

Residential areas in Kuwait City have witnessed a dramatic rise in subsurface water tables over the last three decades. This water rise phenomenon is attributed mainly to over irrigation practices of private gardens along with leakage from domestic and sewage networks. This paper presents a comprehensive study for urban drainage in two selected areas representing the two hydrogeological settings encountered in Kuwait City. In the first area, a vertical drainage scheme was applied successfully over an area of 1 km2. The system has been under continuous operation and monitoring for more than 4 years without problems, providing a permanent solution for the water rise problem in this area. The hydrogeological system has approached steady state conditions and the water levels have dropped to about 3·5 m below the ground surface. In the second area a dual drainage scheme, composing of horizontal and vertical elements, is proposed. Horizontal elements are suggested in the areas where the deep groundwater contains hazardous gases that may pose environmental problems. The proposed drainage scheme in the second area has not yet been implemented. Field tests were conducted to assess the aquifer parameters in both areas and a numerical model has been developed to predict the long-term response of the hydrogeological system in the two areas under consideration.

[Research on stormwater runoff quality of mountain city by source area monitoring].  

PubMed

Stormwater runoff samples were collected from 10 source areas in Mountain City, Chongqing, during five rain events in an attempt to investigate the characteristics of runoff quality and influencing factors. The outcomes are expected to offer practical guidance of sources control of urban runoff pollution. The results indicated that the stormwater runoff of Mountain City presented a strong first flush for almost all events and constituents. The runoff quality indices were also influenced by the rainfall intensity. The concentration of TSS, COD, TN and TP decreased as the rainfall intensity increased. The concentrations of COD and TP in stormwater runoff were highly correlated with TSS concentrations. Suspended solid matter were not only the main pollutant of stormwater runoff but also served as the vehicle for transport of organic matter and phosphorus. Organic matter and phosphorus in stormwatrer runoff were mainly bound to particles, whereas nitrogen was predominantly dissolved, with ammonia and nitrate. A significant difference of stormwater runoff quality was observed among the ten monitored source areas. The highest magnitude of urban stormwater runoff pollution was expected in the commercial area and the first trunk road, followed by the minor road, residential area, parking lot and roof. Urban surface function, traffic volume, population density, and street sweeping practice are the main factors determining spatial differentiation of urban surface runoff quality. Commercial area, the first trunk road and residential area with high population density are the critical sources areas of urban stormwater runoff pollution. PMID:23233965

The influence of urban reconstruction in urban heat island effect: Cangxia area of Fuzhou City, China  

NASA Astrophysics Data System (ADS)

The urban development is usually accompanied with the re-planning and reconstruction of the old urban area, which is one of the key issues of the urban development program. Over the past decade, Fuzhou City of Fujian province, SE China, has speeded up its reconstruction progress. The Cangxia area, located in the southwestern of the city, was replaned and reconstructed to improve people's living conditions because the area was full of intensively-built squatter settlements. In order to study the thermal environmental changes of the Cangxia area before and after the reconstruction, three Landsat TM images of 1986, 1996 and 2006 were utilized to perform feature extractions of the thermal-related information of the area, such as the land surface temperature (LST), impervious surface area (ISA) and vegetation coverage. The quantitative analysis on the relationship between ISA and LST suggested a positive exponential relationship between the two factors. With the assistance of the Urban-Heat-Island Ratio Index (URI), the digital image processing on the three multi-temporal images revealed the spatial and temporal variations of the urban heat island (UHI) effect in the investigated area from 1986 to 2006. The results showed that after the launch of the reconstruction project of this squatter settlement-dominated area, the UHI effect in the area had been greatly mitigated in the past 20 years, since the URI value had been decreased from 0.648 in 1986 to 0.245 in 2006. This owes greatly to the significant decrease in high-density ISAs and the notable increase in vegetation covers. The reconstruction is of benefit to the UHI mitigation of the Cangxia area.

Roles of surface water areas for water and solute cycle in Hanoi city, Viet Nam  

NASA Astrophysics Data System (ADS)

Hanoi city, the capital of Viet Nam, has developed beside the Red river. Recent rapid urbanization of this city has reduced a large number of natural water areas such as lakes, ponds and canals not only in the central area but the suburban area. Contrary, the urbanization has increased artificial water areas such as pond for fish cultivation and landscaping. On the other hand, the urbanization has induced the inflow of waste water from households and various kinds of factories to these water areas because of delay of sewerage system development. Inflow of the waste water has induced eutrophication and pollution of these water areas. Also, there is a possibility of groundwater pollution by infiltration of polluted surface water. However, the role of these water areas for water cycle and solute transport is not clarified. Therefore, this study focuses on the interaction between surface water areas and groundwater in Hanoi city to evaluate appropriate land development and groundwater resource management. We are carrying out three approaches: a) understanding of geochemical characteristics of surface water and groundwater, b) monitoring of water levels of pond and groundwater, c) sampling of soil and pond sediment. Correlation between d18O and dD of precipitation (after GNIP), the Red River (after GNIR) and the water samples of this study showed that the groundwater is composed of precipitation, the Red River and surface water that has evaporation process. Contribution of the surface water with evaporation process was widely found in the study area. As for groundwater monitoring, the Holocene aquifers at two sites were in unconfined condition in dry season and the groundwater levels in the aquifer continued to increase through rainy season. The results of isotopic analysis and groundwater level monitoring showed that the surface water areas are one of the major groundwater sources. On the other hand, concentrations of dissolved Arsenic (filtered by 0.45um) in the pore water of the pond sediments were much higher than the pond water and closed to that of groundwater. Also, other metal elements showed the same trend. This result suggested that Arsenic and other metal elements recharged to these ponds is probably adsorbed and removed by sediments (including organic matters). That is, pond sediment plays an important role for solute transport as a filter of Arsenic and metal elements. The results of this study strongly suggest that the natural and artificial surface water areas have important roles for water cycle and solute transport in Hanoi city. Although the number of the natural water areas is decreasing, dredging of artificial water areas increases the infiltration from the surface to aquifers. Therefore, qualitative and quantitative preservation of the surface water areas is important for conservation of groundwater environment and contribute to sustainable groundwater management in Hanoi city.

Storm surge modeling of Superstorm Sandy in the New York City Metropolitan area  

NASA Astrophysics Data System (ADS)

Even though the New York/New Jersey area does not lie within the typical 'hurricane belt', recent events and the historical record indicate that large infrequent tropical storms have had direct hits on the region, with impacts being amplified due to the nearly right angle bend in the coastline. The recent plan unveiled by New York City's Mayor Bloomberg lays out mitigation strategies to protect the region's communities, infrastructure, and assets from future storms, and numerical simulation of storm surge and wave hazards driven by potential hurricanes plays a central role in developing and evaluating these strategies. To assist in local planning, recovery, and decision-making, we have used the tide, storm surge, and wind wave model ADCIRC+SWAN to simulate storm surge in one of the most populated areas of the United States: the New York City (NYC) metropolitan area. We have generated a new high-resolution triangular finite-element model grid for the region from recent USGS data as well as recent city topographic maps at 2-foot (0.6m) contour intervals, nautical charts, and details of shipping channels. Our hindcast simulations are compared against Superstorm Sandy. We used the City University of New York High Performance Computing Center's Cray XE6tm at the College of Staten Island for these simulations. Hindcasting and analysis of the Superstorm Sandy storm surge and waves indicates that our simulations produce a reasonable representation of actual events. The grid will be used in an ADCIRC-based forecasting system implementation for the region.

Contribution of natural and anthropogenic emissions to acid precipitation formation in the Mexico City Metropolitan Area  

SciTech Connect

The emissions of precursor compounds that contribute significantly the formation of acid precipitation in urban areas are associated with the burning of fossils fuels from mobile, area and point sources. In Mexico City, these include services, institutions and residences aggregated as area sources, as well as industrial point sources, including smelting, refinement of petroleum and power generation. In addition, dusts from soil erosion and lack of vegetation in the urban landscape contribute to modification of natural rain water. It is common knowledge that acid precipitation characterizes a large variety of compounds, as much related to precursor emissions as to prevailing environmental factors. This study attempts to establish the contribution of natural and anthropogenic emissions and meteorological conditions during the rainy season by analysis of spatial and temporal distributions, as of different ions in solution with rain water, as well as the modeling of wind patterns, as represented by using the arc/info software. This study`s results also show the geographic areas impacted by the acid rain phenomenon and the acidification rates in the Mexico City Metropolitan Area during the past 3 years.

Platinum in PM2.5 of the metropolitan area of Mexico City.  

PubMed

The increase in platinum (Pt) in the airborne particulate matter with size ?2.5 µm (PM2.5) in urban environments may be interpreted as result of the abrasion and deterioration of automobile catalyst. Nowadays, about four million vehicles in Mexico City use catalytic converters, which means that their impact should be considered. In order to evaluate the contribution of Pt to environmental pollution of the metropolitan area of Mexico City (MAMC), airborne PM2.5 was collected at five different sites in the urban area (NW, NE, C, SW, SE) in 2011 during April (dry-warm season), August (rainy season) and December (dry-cold season). Analytical determinations were carried out using a ICP-MS with a collision cell and kinetic energy discrimination. The analytical and instrument performance was evaluated with standard road dust reference material (BCR-723). Median Pt concentration in the analyzed particulate was is 38.4 pg m(-3) (minimal value 1 pg m(-3) maximal value 79 pg m(-3)). Obtained Pt concentrations are higher than those reported for other urban areas. Spatial variation shows that SW had Pt concentration significantly higher than NW and C only. Seasonal variation shows that Pt median was higher in rainy season than in both dry seasons. A comparison of these results with previously reported data of PM10 from 1991 and 2003 in the same studied area shows a worrying increase in the concentration of Pt in the air environment of MAMC.

An Aerial Radiological Survey of Selected Areas of the City of North Las Vegas  

SciTech Connect

As part of the proficiency training for the Radiological Mapping mission of the Aerial Measuring System (AMS), a survey team from the Remote Sensing Laboratory-Nellis (RSL-Nellis) conducted an aerial radiological survey of selected areas of the city of North Las Vegas for the purpose of mapping natural radiation background and locating any man-made radioactive sources. Survey areas were selected in collaboration with the City Manager's office and included four separate areas: (1) Las Vegas Motor Speedway (10.6 square miles); (2) North Las Vegas Downtown Area (9.2 square miles); (3) I-15 Industrial Corridor (7.4 square miles); and (4) Future site of University of Nevada Las Vegas campus (17.4 square miles). The survey was conducted in three phases: Phase 1 on December 11-12, 2007 (Areas 1 and 2), Phase 2 on February 28, 2008 (Area 3), and Phase 3 on March 19, 2008 (Area 4). The total completed survey covered a total of 44.6 square miles. The flight lines (without the turns) over the surveyed areas are presented in Figures 1, 2, 3, and 4. A total of eight 2.5-hour-long flights were performed at an altitude of 150 ft above ground level (AGL) with 300 feet of flight-line spacing. Water line and test line flights were conducted over the Lake Mead and Government Wash areas to ensure quality control of the data. The data were collected by the AMS data acquisition system (REDAR V) using an array of twelve 2-inch x 4-inch x 16-inch sodium iodide (NaI) detectors flown on-board a twin-engine Bell 412 helicopter. Data, in the form of gamma energy spectra, were collected continually (every second) over the course of the survey and were geo-referenced using a differential Global Positioning System. Collection of spectral data allows the system to distinguish between ordinary fluctuations in natural background radiation levels and the signature produced by man-made radioisotopes. Spectral data can also be used to identify specific radioactive isotopes. As a courtesy service, with the approval of the U.S. Department of Energy, National Nuclear Security Administration, Nevada Site Office, RSL-Nellis is providing this summary to the office of the Mayor of the City of North Las Vegas along with the gross-count-based exposure rate and man-made count contour maps and GIS shape files in electronic format on a compact disk.

Spatial distribution of triatomines (Reduviidae: Triatominae) in urban areas of the city of Salvador, Bahia, Brazil.  

PubMed

Environmental changes have a strong influence on the emergence and/or reemergence of infectious diseases. The city of Salvador, Brazil--currently the focus of a housing boom linked to massive deforestation--is an example in point as the destruction of the remaining areas of the Atlantic Forest around the city has led to an increased risk for Chagas disease. Human domiciles have been invaded by the triatomine vectors of Trypansoma cruzi, the flagellate protozoan causing Chagas disease, a problem of particular concern in urban/suburban areas of the city such as the Patamares sector in the north-east, where numbers of both the vector and human cases of the disease have increased lately. To control and prevent further deterioration of the situation, the control programme for Chagas disease, developed by the Bahia Center for Zoonosis Control, has divided the area into a grid of designated surveillance units (ZIs) that are subjected to vector examination. In six out of 98 of these ZIs, 988 triatomes were collected and georeferenced during the 3-year period between 2006 and 2009. The hottest months, that are also generally the driest, showed the highest numbers of triatomines with Triatoma tibiamaculata being the predominant species (98.3%) with Panstrongylus geniculatus present only occasionally (0.6%). Fifty-four percent of all triatomines captured were found inside the homes, and 48.6% out of 479 individuals in the affected ZIs selected for analysis tested positive for T. cruzi infection. The study presented here is a pioneering initiative to map the spatial distribution of triatomines based on geographical information systems with the additional aim of contributing to an expanded knowledge-base about T. cruzi and its vectors in urban areas and raise public health awareness of the risks involved.

Ecosystem service value assessment of coastal area in Lianyungang City using LANDSAT images  

NASA Astrophysics Data System (ADS)

This study aims at discovering changes of ecosystem service value based on spatial-temporal variety of land use features on the coastal area in Lianyungang City from 1978 to 2000. Three LANDSAT images (1978 MSS, 1987 TM and 2000 ETM) were used to estimate changes in the size of six land-use categories (forest, cropland, urban, wetland, lakes/rivers and coastal water). Coefficients which integrated from Costanza et al.'s (1997) ecosystem services valuation model and Xie Gaodi et al.'s (2003) "ecosystem services value unit area of Chinese terrestrial ecosystems" were used to estimate changes in ecosystem services delivered by each land categories, and a sensitivity analysis was conducted to determine the affecting factors of ecosystem service value. The total annual ecosystem service values in coastal area of Lianyungang City decreased from RMB 8.23×10^9 in 1978 to RMB 7.53×10^9 in 1987, however it increased from RMB 7.53×10^9 in 1987 to RMB 10.73×10^9 in 2000. The decline of ecosystem service value from 1978 to 1987 is largely attributable to 53.49% loss of forest at the same period, while the increase of service value is contributed by 147.70% increase of wetland from 1987 to 2000. Change of wetland and forest has the major contribution to the change of total ecosystem service value of Liangyungang city. Waste treatment, water supply and climate regulation are the dominant ecosystem services of this area. Forest and wetland should be strictly conserved in further urban development.

[Application of niche theory in evaluation of main tourism scenic areas in Zhangjiajie City].  

PubMed

Five tourism scenic areas in Zhangjiajie City were selected as research objects, and fifty kinds of resource conditions affecting the development of tourism scenic area were taken as evaluation indices. Through disposing and consolidating the indices level by level, an analysis was made on the niche breadth and niche overlap of the five tourism scenic areas at three levels (I, II, and III). In the five scenic areas, index level had significant effects on the niche breadth (F = 10.278, P = 0.006), but less effects on the relative niche breadth, suggesting that in the evaluation of the development potential of tourism scenic area, relative niche breadth was more reasonable than absolute niche breadth. From level III to level I, the niche overlap of the five scenic areas was increasing, indicating that level choice would affect the evaluation of the actual niche overlap of the scenic areas. With the progressive refinement of the indices to certain level, and when the difference between observed and Monte Carlo-simulated Pianka indices achieved to significant level, this index level could be used as the minimum standard of the refinement, and the simulated niche overlap could be taken as an important reference in the competition evaluation of tourism scenic area.

Salt Lake City Area Integrated Projects Electric Power Marketing. Draft environmental impact statement: Volume 1, Summary  

SciTech Connect

The Salt Lake City Area Office of the Western Area Power Administration (Western) markets electricity produced at hydroelectric facilities operated by the Bureau of Reclamation. The facilities are known collectively as the Salt Lake City Area Integrated Projects (SLCA/IP) and include dams equipped for power generation on the Green, Gunnison, Rio Grande, and Colorado rivers and on Deer and Plateau creeks in the states of Wyoming, Utah, Colorado, Arizona, and New Mexico. Of these facilities, only the Glen Canyon Unit, the Flaming Gorge Unit, and the Aspinall Unit (which includes Blue Mesa, Morrow Point, and Crystal dams) are influenced by Western`s power scheduling and transmission decisions. The EIS alternatives, called commitment-level alternatives, reflect combinations of capacity and energy that would feasibly and reasonably fulfill Western`s firm power marketing responsibilities, needs, and statutory obligations. The viability of these alternatives relates directly to the combination of generation capability of the SLCA/IP with energy purchases and interchange. The economic and natural resource assessments in this environmental impact statement (EIS) include an analysis of commitment-level alternatives. Impacts of the no-action altemative are also assessed. Supply options, which include combinations of electrical power purchases and hydropower operational scenarios reflecting different operations of the dams, are also assessed. The EIS evaluates the impacts of these scenarios relative to socioeconomics, air resources, water resources, ecological resources, cultural resources, land use, recreation, and visual resources.

Measurements of Criteria Pollutants in Suburban Locations in the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

In the town of Santa Ana in the southern part of the Mexico City Metropolitan Area (MCMA) at an approximate height of 370 meters above the Valley of Mexico, a series of criteria pollutants (nitrogen dioxide, ozone, sulfur dioxide, and carbon monoxide) and meteorological parameters (wind speed and direction, temperature and relative humidity) were measured during the MCMA-2003 field campaign during April 2003. Santa Ana is considered a border site, agriculture being the predominant activity. The generated data in Santa Ana was compared with those from two representative atmospheric monitoring stations from the southeast zone (CENICA Supersite) and southwest (Revolucion Station) of Mexico City. The carbon monoxide and ozone concentrations measured in Santa Ana are atypical for a rural area. The sulfur dioxide and nitrogen dioxide concentrations are characteristic of the local activity. The average obtained during the measurement time for carbon monoxide was 0.86 ppm, the presence of the contaminant was within a 0.3 to 1.5 ppm range, 5 to 95 percentile, and does not follow the observed behavior of the monitoring stations that are located inside the urban area, although during the night (10 pm to 6 am) the carbon monoxide in Santa Ana was preset in levels from 0.4 to 1.5 ppm, 5 to 95 percentiles, average 0.92 ppm, above the reported concentrations at Revolucion Station, levels from 0.1 to 1.7 ppm, 5 to 95 percentiles; average 0.72 ppm. The presence of this contaminant can be attributed to transportation and accumulation phenomena. The ozone daytime behavior is similar to the one observed in the CENICA and Revolucion stations, but with a lower magnitude, the daily maximum generally occuring 2 or 3 hours after the urban stations. The one-hour average maximum values were 133 ppb in Santa Ana area and 188 ppb in the city. During the night the average concentrations were 37 ppb in Santa Ana and 17 ppb in the urban area. Nevertheless, the ozone average value in Santa Ana during the study was 49 ppb, slightly higher than the one obtained in the urban area, which was 44 ppb. The presence of this contaminant can be possibly attributed to the transportation and accumulation factors as well as to the low reactivity due to the absence of NOx, as explained in Dommen Josef and Prévôt, S.H. André, 2002, Characterization of the photooxidant formation in the metropolitan area of Milan from aircraft measurements, Journal of Geophysical Research, 107 (D22): 8197, doi: 10.1029/2000JD000283.

Interaction between surface water areas and groundwater in Hanoi city, Viet Nam  

NASA Astrophysics Data System (ADS)

Hanoi is the capital of Viet Nam and the second largest city in this country (population: 6.45 million in 2009). Hanoi city has developed along the Red River and has many lakes, ponds and canals. However, recent rapid urbanization of this city has reduced number of natural water areas such as ponds and lakes by reclamation not only in the central area but the suburban area. Canals also have been reclaimed or cut into pieces. Contrary, number of artificial water areas such as fish cultivation pond has rapidly increased. On the other hand, various kind of waste water flows into these natural and artificial water areas and induces pollution and eutrophication. These waste waters also have possibility of pollution of groundwater that is one of major water resources in this city. In addition, groundwater in this area has high concentrations of Arsenic, Fe and NH4. Thus, groundwater use may causes re-circulation of Arsenic. However, studies on the interaction between surface water areas and groundwater and on the role of surface water areas for solute transport with water cycle are a few. Therefore, we focused on these points and took water samples of river, pond and groundwater from four communities in suburban areas: two communities are located near the Red River and other two are far from the River. Also, columnar sediment samples of these ponds were taken and pore water was abstracted. Major dissolved ions, metals and stable isotopes of oxygen and hydrogen of water samples were analyzed. As for water cycle, from the correlation between ?18O and ?D, the Red River water (after GNIR) were distributed along the LMWL (?D=8.2?18O+14.1, calculated from precipitation (after GNIP)). On the other hand, although the pond waters in rainy season were distributed along the LMWL, that in dry season were distributed along the local evaporation line (LEL, slope=5.6). The LEL crossed with the LMWL at around the point of weighted mean values of precipitation in rainy season and of the Red river. Groundwater samples were also distributed along the LEL and there was no seasonal change. Thus, groundwater in these communities was mainly recharged by mixing of precipitation/the Red River and evaporated water bodies. Considering the land use in these communities, evaporated water bodies were considered to be not only ponds but also paddy fields. As for solute transport, concentration of dissolved Arsenic (filtered by 0.45?m) of the pond water (3 - 10 ?g/L) was slightly higher than the Red River (~ 3 ?g/L) and was much lower than that of groundwater (~ 60 ?g/L). On the other hand, concentration of dissolved Arsenic in the pore water of sediments (10 - 85 ?g/L) was close to groundwater. Also, other metal elements showed the same trend. Therefore, Arsenic and other metal elements recharged to these ponds were considered to be adsorbed by sediments (including organic matters). That is, pond sediments played an important role as a filter of metal elements. The results of this study strongly suggested that the surface water areas such as ponds and paddy fields are one of main groundwater sources. Also, ponds play important role for solute transport of metal elements. Therefore, management of these surface water areas is important to conserve groundwater environment.

Hydrology and snowmelt simulation of Snyderville Basin, Park City, and adjacent areas, Summit County, Utah  

USGS Publications Warehouse

Increasing residential and commercial development is placing increased demands on the ground- and surface-water resources of Snyderville Basin, Park City, and adjacent areas in the southwestern corner of Summit County, Utah. Data collected during 1993-95 were used to assess the quantity and quality of the water resources in the study area. Ground water within the study area is present in consolidated rocks and unconsolidated valley fill. The complex geology makes it difficult to determine the degree of hydraulic connection between different blocks of consolidated rocks. Increased ground-water withdrawal during 1983- 95 generally has not affected ground-water levels. Ground-water withdrawal in some areas, however, caused seasonal fluctuations and a decline in ground-water levels from 1994 to 1995, despite greater-than-normal recharge in the spring of 1995. Ground water generally has a dissolved-solids concentration that ranges from 200 to 600 mg/L. Higher sulfate concentrations in water from wells and springs near Park City and in McLeod Creek and East Canyon Creek than in other parts of the study area are the result of mixing with water that discharges from the Spiro Tunnel. The presence of chloride in water from wells and springs near Park City and in streams and wells near Interstate Highway 80 is probably caused by the dissolution of applied road salt. Chlorofluorocarbon analyses indicate that even though water levels rise within a few weeks of snowmelt, the water took 15 to 40 years to move from areas of recharge to areas of discharge. Water budgets for the entire study area and for six subbasins were developed to better understand the hydrologic system. Ground-water recharge from precipitation made up about 80 percent of the ground-water recharge in the study area. Ground-water discharge to streams made up about 40 percent of the surface water in the study area and ground-water discharge to springs and mine tunnels made up about 25 percent. Increasing use of ground water has the potential to decrease discharge to streams and affect both the amount and quality of surface water in the study area. A comparison of the 1995 to 1994 water budgets emphasizes that the hydrologic system in the study area is very dependent upon the amount of annual precipitation. Although precipitation on the study area was much greater in 1995 than in 1994, most of the additional water resulted in additional streamflow and spring discharge that flows out of the study area. Ground-water levels and groundwater discharge are dependent upon annual precipitation and can vary substantially from year to year. Snowmelt runoff was simulated to assist in estimating ground-water recharge to consolidated rock and unconsolidated valley fill. A topographically distributed snowmelt model controlled by independent inputs of net radiation, meteorological parameters, and snowcover properties was used to calculate the energy and mass balance of the snowcover.

DISTRIBUTION OF DERMATOPHYTES FROM SOILS OF URBAN AND RURAL AREAS OF CITIES OF PARAIBA STATE, BRAZIL  

PubMed Central

SUMMARY The dermatophytes, keratinophilic fungi, represent important microorganisms of the soil microbiota, where there are cosmopolitan species and others with restricted geographic distribution. The aim of this study was to broaden the knowledge about the presence of dermatophytes in soils of urban (empty lots, schools, slums, squares, beaches and homes) and rural areas and about the evolution of their prevalence in soils of varying pH in cities of the four mesoregions of Paraiba State, Brazil. Soil samples were collected from 31 cities of Paraiba State. Of 212 samples, 62% showed fungal growth, particularly those from the Mata Paraibana mesoregion (43.5%), which has a tropical climate, hot and humid. Soil pH varied from 4.65 to 9.06, with 71% of the growth of dermatophytes occurring at alkaline pH (7.02 - 9.06) (? = 0.000). Of 131 strains isolated, 57.3% were geophilic species, particularly Trichophyton terrestre (31.3%) and Mycrosporum gypseum (21.4%). M. nanum and T. ajelloi were isolated for the first time in Paraiba State. The zoophilic species identified were T. mentagrophytes var. mentagrophytes (31.3 %) and T. verrucosum (7.6 %), and T. tonsurans was isolated as an anthropophilic species. The soils of urban areas including empty lots, schools, slums and squares of cities in the mesoregions of Paraiba State were found to be the most suitable reservoirs for almost all dermatophytes; their growth may have been influenced by environmental factors, soils with residues of human and/or animal keratin and alkaline pH.

New Magnetic and Geochemical Results on Topsoils of the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

The Metropolitan Area of Mexico city is a region well known for intense industrial and commercial activity. The potential sources of the heavy metal pollutants are assumed to be petroleum processing, production of iron material, manufacturing, coal combustion, commercial and automobile exhaust. New samples were collected from industrial, roadside, residential and public parks in the urban areas around the city and added to two previous field campaigns (2003 and 2005). Localities selected for the study represent, presumably, different heavy metal pollution levels and sources. At each sampling point, the top 2 cm layer of the soil profile was collected with a stainless steel trowel and stored in a plastic bag. The elements Fe, Cu and Zn concentrations were determined by EDXRF (Philips PW1400 apparatus) on bulk- sample pressed, boric-acid backed pellets. Metal concentrations of Pb, Ni, Cr, and V were analyzed by ICP-MS with a VG Elemental PQ3 instrument. Magnetic mineralogy in bulk soil samples was investigated by low-field susceptibility using a Kappabridge KLY2. Remanent magnetizations (ARM and IRM) and Hysteresis loops of micro samples had been carried out at room temperature. Bivariate analysis on different ratios of magnetic parameters was employed to characterize the pollution sources.

Naturally Occurring Arsenic in Ground Water, Norman, Oklahoma, 2004, and Remediation Options for Produced Water  

USGS Publications Warehouse

In 2000, the U.S. Environmental Protection Agency (EPA) reviewed the arsenic drinking water standard for public water supplies. Considering the available research and statistics on the health effects of arsenic ingestion, the EPA reduced the Maximum Contaminant Level (MCL) for public drinking water from 50 micrograms per liter (?g/L) to 10 ?g/L (U.S. Environmental Protection Agency, 2001a). As a result of the more stringent standard, the EPA estimates that about 3,000 public water providers across the United States must take action to meet the new standard before it becomes effective on January 23, 2006 (U.S. Environmental Protection Agency, 2001b). The City of Norman (City) is one of several Oklahoma municipalities affected by the new arsenic standard. About 20 percent of Norman?s water is supplied by wells completed in the Central Oklahoma (Garber-Wellington) aquifer; the rest is supplied by Lake Thunderbird (fig. 1) or purchased from Oklahoma City. The Norman well field is composed of 24 active wells, and water produced from about half of the wells will not be in compliance with the new MCL (figs. 2 and 3). Chemical treatment of water with elevated arsenic is possible, but it is generally cost prohibitive. Another costly solution is simply to abandon the high-arsenic wells and replace them with new wells in low-arsenic areas. In the next phase of well construction beginning in 2005, the City plans to construct as many as 30 new wells in northeast Norman (Bryan Mitchell, City of Norman, oral commun., 2005). The new wells will replace production lost to the new arsenic standard and add new production to keep pace with rapidly growing consumer demand. Well modification to exclude arsenic-bearing water from existing wells is a more cost-effective solution, but it requires a great deal of knowledge about local aquifer properties and individual well dynamics to decide which wells are good candidates for modification. With the goal of determining if well modification can be used to bring some of Norman?s high-arsenic wells into compliance with the new arsenic standard, the EPA Office of Research and Development (ORD) initiated a three-year research project in 2003 with participation from the U.S. Geological Survey (USGS), Oklahoma State University, and the City of Norman. The primary objectives of the project are to: (1) determine where naturally occurring arsenic is entering wells by collecting water samples at different depths, (2) investigate the utility of new methods for collecting water-quality data in a pumping well, (3) better understand the stratigraphy and composition of aquifer rocks, (4) assess 10 wells for the possibility of arsenic remediation by well modification, and (5) evaluate the effectiveness of well modification in bringing marginal wells into compliance with the new arsenic MCL. The purpose of this report is to describe the occurrence of arsenic in ground water near Norman, Oklahoma, and available options for reducing arsenic concentrations in produced ground water.

Water Hazard in Coastal Area: Actions for conserving and protecting European World Heritage Cities  

NASA Astrophysics Data System (ADS)

It is well known that many of the European UNESCO World Heritage sites and cities are closely related to water bodies in their different forms, as they have close links with the sea (such as Venice, San Rossore, Dubrovnik) and with rivers (like Florence, Rome, Ferrara, etc). Surely there are many others with problems of water supply, water treatment, wastewater disposal, etc. The main objective of the work is therefore to institute measures which will permit to contribute towards the conservation and protection of such precious heritage sites and cities, particularly in coastal area, in the context of present urbanization and climatic modifications. It has therefore become necessary to identify and classify not only urban centres of historical importance but also historical hydraulic structures and works developed for both beneficial and harmful water management, hereinafter referred to as good water and bad water respectively. Another objective is to raise the awareness of institutions and the public in general on the historical values of Heritage cities and hence the need to protect them. The main activities of the study are directed at the following: 1) Collection and collation of information and documentation on water sources, intakes and distribution structures, flood events especially around urban centres, structural characteristics of bridges, defensive hydraulic structures of rivers from ancient times to the present. 2) Creation of an integrative water-urban data base in the form of a virtual museum. 3) Design and preparation of feasibility strategies for relevant historical works for renovation purposes and also hydrological analysis of flood events and reconstruction of historical flood series towards re-qualification of urban and riverine environments in the face of climate change. 4) Hydraulic risk analysis of complex hydraulic systems, performing flooding scenarios at different flow rates.

Availability and quality of water from the bedrock aquifers in the Rapid City area, South Dakota  

USGS Publications Warehouse

An evaluation made in cooperation with the U.S. Bureau of Reclamation of the availability and quality of water from the bedrock aquifers in the Rapid City area, South Dakota, concluded that Madison aquifer has the greatest potential for additional development of the three major aquifers investigated (the Inyan Kara, the Minnelusa, and the Madison). Ground-water availability and quality were evaluated on the basis of unit thickness and depth, potentiometric-surface altitudes and gradients, estimated recharge and discharge rates, estimated aquifer transmissivities and storage coefficients, reported yields of existing wells, and concentrations of ions in the water that may affect its use as a community supply. The Inyan Kara aquifer has the least potential for additional development because of reported small well yields , the proximity of the outcrop, and concentration of radium-226 exceeding 5 picocuries per liter. The Minnelusa aquifer is unsuitable for development in the eastern two-thirds of the study area because the concentrations of dissolved solids and sulfate commonly exceed the recommended maximum level for community water supplies. The Madison aquifer has the greatest potential for additional development because it has the greatest recharge rate, has areas with significant fracture permeability, yields as much as 500 gallons per minute to wells, and has satisifactory water quality, though it is hard (hardness 120 to 180 milligrams per liter) to very hard (hardness greater than 180 milligrams per liter).

Nonfatal injuries 1 week after hurricane sandy - new york city metropolitan area, october 2012.  

PubMed

On October 29, 2012, Hurricane Sandy (Sandy) made landfall in densely populated areas of New York, New Jersey, and Connecticut. Flooding affected 51 square miles (132 square kilometers) of New York City (NYC) and resulted in 43 deaths, many caused by drowning in the home, along with numerous storm-related injuries. Thousands of those affected were survivors of the World Trade Center (WTC) disaster of September 11, 2001 (9/11) who had previously enrolled in the WTC Health Registry (Registry) cohort study. To assess Sandy-related injuries and associated risk factors among those who lived in Hurricane Sandy-flooded areas and elsewhere, the NYC Department of Health and Mental Hygiene surveyed 8,870 WTC survivors, who had provided physical and mental health updates 8 to 16 months before Sandy. Approximately 10% of the respondents in flooded areas reported injuries in the first week after Sandy; nearly 75% of those had more than one injury. Injuries occurred during evacuation and clean-up/repair of damaged or destroyed homes. Hurricane preparation and precautionary messages emphasizing potential for injury hazards during both evacuation and clean-up or repair of damaged residences might help mitigate the occurrence and severity of injury after a hurricane.

Measurement and evaluation of the environmental noise levels in the urban areas of the city of Nis (Serbia).  

PubMed

The environmental noise level represents one of the key factors of life quality in urban areas of modern cities. A continuous monitoring of the noise levels and the analysis of results have become a necessity when we discuss a possible recovery of those areas with high levels of noise pollution, and particularly, those zones which were designed for specific activities, e.g., areas around hospitals and schools. The city of Nis, Serbia, owing to the permanent long-term noise monitoring, possesses a database containing figures related to the noise levels at relevant locations in the city, which can serve as a basis for an analysis of the change of conditions, their tendencies in the future, and recognizing factors which influence the danger of noise pollution. The paper involves an analysis of the environmental noise level collected during the previous years. PMID:24197556

Vehicle Traffic as a Source of Particulate Polycyclic Aromatic Hydrocarbon Exposure in the Mexico City Metropolitan Area  

PubMed Central

Surface properties of aerosols in the Mexico City metropolitan area have been measured in a variety of exposure scenarios related to vehicle emissions in 2002, using continuous, real-time instruments. The objective of these experiments is to describe ambient and occupational particulate polycyclic aromatic hydrocarbon (PAH) concentrations associated with vehicular traffic and facilities using diesel vehicles. Median total particulate PAH concentrations along Mexico City’s roadways range from 60 to 910 ng m?3, averaged over a minimum of 1 h. These levels are approximately 5 times higher than concentrations measured in the United States and among the highest measured ambient values reported in the literature. The ratio of particulate PAH concentration to aerosol active surface area is much higher along roadways and in other areas of fresh vehicle emissions, compared to ratios measured at sites influenced more by aged emissions or noncombustion sources. For particles freshly emitted by vehicles, PAH and elemental carbon (EC) concentrations are correlated because they both originate during the combustion process. Comparison of PAH versus EC and active surface area concentrations at different locations suggests that surface PAH concentrations may diminish with particle aging. These results indicate that exposure to vehicle-related PAH emissions on Mexico City’s roadways may present an important public health risk. PMID:15180054

Ground Subsidence in the Granada City and Surrounding Area (Spain) using DInSAR Monitoring  

NASA Astrophysics Data System (ADS)

Differential SAR interferometry (DInSAR) is a remote sensing technique which has been successfully used, since the final of the eighties, for different applications such as coseismic deformation mapping, volcano deformation monitoring, landslides monitoring and subsidence detection among others. This is an alternative technique to obtain measurements of the surface displacement providing better spatial resolution and comparable accuracy while being less time consuming than conventional surveying methods. However, spatial and temporal decorrelation and atmospheric signal contributions in repeat-pass SAR interferometry often hamper the accurate measurement of surface displacements in SAR interferograms. In 1999, the POLIMI SAR group implemented a different process allowing overcoming these difficulties by interpreting time-series of interferometric phases at coherent point scatterers. This technique was called the Permanent Scatterer techniques, which allow us to measure deformation with accuracies of millimetres per year. Since then, other techniques have been suggested following similar processing lines, such as the Persistent Scatterer Interferometry (PSI) developed at Delft Technical University (The Netherlands). In this study, we apply PSI technique using two time-series of 32 ERS-1/2 and 22 ENVISAT ASAR acquisitions of the Granada Basin, located at the central sector of the Betic Cordillera (southern Spain), covering the period from 1992 to 2005. This is the first time that the PSI technique is applied to derive displacement information in this southern Iberia region. This technique is very useful for the analysis of subsidence in urban areas, where angular structures produce efficient reflectors that dominate the background scattering. However, man-made structures are absent from most of the Earth's surface, such is the case in part of the studied area. After this first data processing, several subsidence areas have been detected in the southern part of Granada city and nearby villages. At the moment, some investigations are being carried out in order to find the relationship between the detected deformation and the tectonic deformation present in the area.

Chemical evolution of volatile organic compounds in the outflow of the Mexico City Metropolitan area  

NASA Astrophysics Data System (ADS)

The volatile organic compound (VOC) distribution in the Mexico City Metropolitan Area (MCMA) and its evolution as it is uplifted and transported out of the MCMA basin was studied during the 2006 MILAGRO/MIRAGE-Mex field campaign. The results show that in the morning hours in the city center, the VOC distribution is dominated by non-methane hydrocarbons (NMHCs) but with a substantial contribution from oxygenated volatile organic compounds (OVOCs), predominantly from primary emissions. Alkanes account for a large part of the NMHC distribution in terms of mixing ratios. In terms of reactivity, NMHCs also dominate overall, especially in the morning hours. However, in the afternoon, as the boundary layer lifts and air is mixed and aged within the basin, the distribution changes as secondary products are formed. The WRF-Chem (Weather Research and Forecasting with Chemistry) model and MOZART (Model for Ozone and Related chemical Tracers) were able to reproduce the general features of the daytime cycle of the VOC OH reactivity distribution showing that NMHCs dominate the distribution except in the afternoon hours and that the VOC OH reactivity peaks in the early morning due to high morning emissions from the city into a shallow boundary layer. The WRF-Chem and MOZART models showed higher reactivity than the experimental data during the nighttime cycle, perhaps indicating problems with the modeled nighttime boundary layer height. In addition, a plume was studied in which air was advected out of the MCMA and intercepted downwind with the DOE G1 on 18~March and the NCAR C130 one day later on 19~March. A number of identical species measured aboard each aircraft gave insight into the chemical evolution of the plume as it aged and was transported as far as 1000 km downwind. Ozone and many OVOCs were photochemically produced in the plume. The WRF-Chem and MOZART models were used to examine the spatial and temporal extent of the 19~March plume and to help interpret the OH reactivity in the downwind plume. The model results generally showed good agreement with experimental results for the total VOC OH reactivity downwind and gave insight into the distributions of VOC chemical classes downwind. A box model with detailed gas phase chemistry (NCAR Master Mechanism), initialized with concentrations observed at one of the ground sites in the MCMA, was used to examine the expected evolution of specific VOCs over a 1-2~day period. The models clearly supported the experimental evidence for NMHC oxidation leading to the formation of OVOCs downwind, which then become the primary fuel for ozone production far away from the MCMA.

Heavy metals in seawater, sediments, and biota from the coastal area of Yancheng City, China.  

PubMed

A systematic investigation was carried out to analyze the concentration levels of heavy metals in sample seawater, sediments, and biota collected from the coastal area of Yancheng City in Jiangsu Province, China. The authors assessed the impact of these heavy metals in different environmental samples in terms of potential risks to ecology and also to the human population exposed to this area. In addition, a further investigation was carried out to test the toxicity to early-life-stage zebrafish (Danio rerio) of selected samples that were considered to pose higher levels of potential risks to ecology or human health. Chemical analysis showed relatively higher concentrations of heavy metals in the seawater and biota samples collected from Xiangshui County and Binhai County, China. The heavy metal concentrations in different samples collected from the close vicinity of Dafeng Port, China, were also considerable. In all seawater and sediment samples, heavy metals showed a relatively moderate level of risk to ecological species; for consumption of marine organisms, heavy metals had adverse impacts on human health. Toxicity assessment indicated that the selected environmental samples or their extracts had significant toxicity to zebrafish early-life stages, including lethality, teratogenicity, and hatching delay (or advance). Thus the present study provides highly useful and important information on heavy metal pollution in Jiangsu Province. PMID:24619970

Processing of Soot in an Urban Environment: Case Study from the Mexico City Metropolitan Area  

SciTech Connect

Chemical composition, size, and mixing state of atmospheric particles are critical in determining their e ffects on the environment. There is growing evidence that soot aerosols play a particularly important role in both climate and human health, but still relatively little is known of their physical and chemical nature. In addition, the atmo- 5 spheric residence times and removal mechanisms for soot are neither well understood nor adequately represented in regional and global climate models. To investigate the effect of locality and residence time on properties of soot and mixing state in a polluted urban environment, particles of diameter 0.2–2.0 µm were collected in the Mexico City Metropolitan Area (MCMA) during the MCMA-2003 field campaign from various sites 10 within the city. Individual particle analysis by di fferent electron microscopy methods coupled with energy dispersed X-ray spectroscopy, and secondary ionization mass spectrometry show that freshly-emitted soot particles become rapidly processed in the MCMA. Whereas fresh particulate emissions from mixed-tra ffic are almost entirely carbonaceous, consisting of soot aggregates with liquid coatings suggestive of unburned 15 lubricating oil and water, ambient soot particles which have been processed for less than a few hours are heavily internally mixed, primarily with ammonium sulfate. Single particle analysis suggests that this mixing occurs through several mechanisms that require further investigation. In light of previously published results, the internally-mixed nature of processed soot particles is expected to a ffect heterogeneous chemistry on 20 the soot surface, including interaction with water during wet-removal.

Refined estimation of solar energy potential on roof areas using decision trees on CityGML-data  

NASA Astrophysics Data System (ADS)

We present a decision tree for a refined solar energy plant potential estimation on roof areas using the exchange format CityGML. Compared to raster datasets CityGML-data holds geometric and semantic information of buildings and roof areas in more detail. In addition to shadowing effects ownership structures and lifetime of roof areas can be incorporated into the valuation. Since the Renewable Energy Sources Act came into force in Germany in 2000, private house owners and municipals raise attention to the production of green electricity. At this the return on invest depends on the statutory price per Watt, the initial costs of the solar energy plant, its lifetime, and the real production of this installation. The latter depends on the radiation that is obtained from and the size of the solar energy plant. In this context the exposition and slope of the roof area is as important as building parts like chimneys or dormers that might shadow parts of the roof. Knowing the controlling factors a decision tree can be created to support a beneficial deployment of a solar energy plant. Also sufficient data has to be available. Airborne raster datasets can only support a coarse estimation of the solar energy potential of roof areas. While they carry no semantically information, even roof installations are hardly to identify. CityGML as an Open Geospatial Consortium standard is an interoperable exchange data format for virtual 3-dimensional Cities. Based on international standards it holds the aforementioned geometric properties as well as semantically information. In Germany many Cities are on the way to provide CityGML dataset, e. g. Berlin. Here we present a decision tree that incorporates geometrically as well as semantically demands for a refined estimation of the solar energy potential on roof areas. Based on CityGML's attribute lists we consider geometries of roofs and roof installations as well as global radiation which can be derived e. g. from the European Solar Radiation Atlas. After identifying the shadow free area of the roof we recognize manufacturer dependent device sizes as well as lifetime of the building. While more and more CityGML data will be available in future or approach is a valuable contribution for decision makers and private households to estimate the return on invest of solar energy plants.

Oklahoma Center for High Energy Physics (OCHEP)  

SciTech Connect

The DOE EPSCoR implementation grant, with the support from the State of Oklahoma and from the three universities, Oklahoma State University, University of Oklahoma and Langston University, resulted in establishing of the Oklahoma Center for High Energy Physics (OCHEP) in 2004. Currently, OCHEP continues to flourish as a vibrant hub for research in experimental and theoretical particle physics and an educational center in the State of Oklahoma. All goals of the original proposal were successfully accomplished. These include foun- dation of a new experimental particle physics group at OSU, the establishment of a Tier 2 computing facility for the Large Hadron Collider (LHC) and Tevatron data analysis at OU and organization of a vital particle physics research center in Oklahoma based on resources of the three universities. OSU has hired two tenure-track faculty members with initial support from the grant funds. Now both positions are supported through OSU budget. This new HEP Experimental Group at OSU has established itself as a full member of the Fermilab D0 Collaboration and LHC ATLAS Experiment and has secured external funds from the DOE and the NSF. These funds currently support 2 graduate students, 1 postdoctoral fellow, and 1 part-time engineer. The grant initiated creation of a Tier 2 computing facility at OU as part of the Southwest Tier 2 facility, and a permanent Research Scientist was hired at OU to maintain and run the facility. Permanent support for this position has now been provided through the OU university budget. OCHEP represents a successful model of cooperation of several universities, providing the establishment of critical mass of manpower, computing and hardware resources. This led to increasing Oklahoma�¢����s impact in all areas of HEP, theory, experiment, and computation. The Center personnel are involved in cutting edge research in experimental, theoretical, and computational aspects of High Energy Physics with the research areas ranging from the search for new phenomena at the Fermilab Tevatron and the CERN Large Hadron Collider to theoretical modeling, computer simulation, detector development and testing, and physics analysis. OCHEP faculty members participating on the D0 collaboration at the Fermilab Tevatron and on the ATLAS collaboration at the CERN LHC have made major impact on the Standard Model (SM) Higgs boson search, top quark studies, B physics studies, and measurements of Quantum Chromodynamics (QCD) phenomena. The OCHEP Grid computing facility consists of a large computer cluster which is playing a major role in data analysis and Monte Carlo productions for both the D0 and ATLAS experiments. Theoretical efforts are devoted to new ideas in Higgs bosons physics, extra dimensions, neutrino masses and oscillations, Grand Unified Theories, supersymmetric models, dark matter, and nonperturbative quantum field theory. Theory members are making major contributions to the understanding of phenomena being explored at the Tevatron and the LHC. They have proposed new models for Higgs bosons, and have suggested new signals for extra dimensions, and for the search of supersymmetric particles. During the seven year period when OCHEP was partially funded through the DOE EPSCoR implementation grant, OCHEP members published over 500 refereed journal articles and made over 200 invited presentations at major conferences. The Center is also involved in education and outreach activities by offering summer research programs for high school teachers and college students, and organizing summer workshops for high school teachers, sometimes coordinating with the Quarknet programs at OSU and OU. The details of the Center can be found in http://ochep.phy.okstate.edu.

Water conservation as a long-range strategy in municipal water supply planning: the case of Oklahoma  

SciTech Connect

This study is concerned with Oklahoma water managers' attitudes toward the adoption or rejection of long-term water conservation options in small and medium sized cities under 50,000 in population. In focusing upon Oklahoma water managers' attitudes, the following questions are addressed: (1) What factors influence Oklahoma water managers' attitudes toward the adoption or rejection of long-term water conservation measures. (2) What are the major incentives or disincentives that may encourage or discourage the adoption and implementing of long-term water conservation alternatives at the municipal level in Oklahoma. (3) What are the distinct geographical variations in attitudes toward adopting water conservation policies. To address these and related questions, a questionnaire was mailed to each of the water managers in the selected Oklahoma towns and cities. Results of the study indicated that local water managers considered local governments as the most appropriate body to deal with water management issues. Local water managers in Oklahoma also place heavy reliance upon traditional structural solutions. If these solutions prove to be inadequate, long-term water conservation alternatives become more appealing. However, Oklahoma water managers in the selected cities and towns expressed their profound concerns about the potential revenue loss if long-term water conservation measures were to be adopted and implemented.

Delineation of flood-prone areas and the identification of residential hotspots for two African cities  

NASA Astrophysics Data System (ADS)

This work employs two GIS-based frameworks for identifying the urban residential hot spots. This is done by overlaying a map of potentially flood prone areas (the topographic wetness index, TWI) and a map of urban morphology types (UMT) classified as residential. The topographic wetness index (TWI, Qin et al. 2011) allows for the delineation of a portion of a hydrographic basin potentially exposed to flood inundation by identifying all the areas characterized by a topographic index that exceeds a given threshold. The urban morphological types (Pauleit and Duhme 2000, Gill et al. 2008, Cavan et al. 2012) form the foundation of a classification scheme which brings together facets of urban form and function. The application of the UMTs allows the delineation of geographical units. The distinction of UMTs at a 'meso'-scale (i.e. between the city level and that of the individual units) makes a suitable basis for the spatial analysis of cities. The TWI threshold value depends on the resolution of the digital elevation model (DEM), topology of the hydrographic basin (i.e. urban, peri-urban or rural) and the constructed infrastructure (Manfreda et al. 2011). This threshold value is usually calibrated based on the results of detailed delineation of the inundation profile for selected zones. In this study, the TWI threshold is calibrated based on the calculated inundation profiles for various return periods for selected zones within the basin through a Bayesian framework. The Bayesian framework enables the probabilistic characterization of the threshold value by calculating the complementary probability of false delineation of flood prone zones as a function of various threshold values. For a given return period, the probability of false delineation is calculated as the sum of the probability of indicating a zone flood prone which is not indicated as such by the inundation profile and the probability that a zone is indicated as not flood prone but indicated as flood prone by the inundation profile. Applying the above-mentioned procedure, taking into account all available information on the inundation profiles for various zones within the basin, leads to a probability distribution for the TWI threshold value. In the next step, the urban residential hot spots to flooding are delineated in the GIS environment by overlaying the map of TWI and the UMT units classified as residential for various percentiles of the TWI threshold. Differences in exposure characteristics can be assessed for a range of different residential types, including for example between condominium/multi-storey, single storey stone/concrete and areas predominantly associated with mud/wood construction. For each percentile value considered, the delineated flood-prone residential areas and the number of people potentially affected to flooding are calculated. Moreover, the potential dependence of the estimated threshold percentiles on the flooding return period is investigated. As a demonstration, the urban residential hotspots to flooding are delineated for 16th, 50th and 84th percentiles of the TWI value for the cities of Dar es Salaam and Addis Ababa.

This Technical Quarterly Report is for the reporting period July 1, 2000 to September 30, 2000. The report provides details of the work done on the project entitled ''Enhanced Oil Recovery with Downhole Vibration Stimulation in Osage County Oklahoma''. The project is divided into nine separate tasks. Since this is the first Quarterly report, much of the work done is of a preliminary nature. Several of the tasks are being worked on simultaneously, while other tasks are dependent on earlier tasks being completed. The selection of the pilot test area has been completed. The drilling of the test well is waiting on rig availability. Phillips has begun sonic core testing of offset cores, waiting on the core from the well to be drilled. Design work is progressing for the tool, which will be built to fit the test well. Installation of monitoring equipment and the downhole vibration tool will occur after the well is drilled. Technical transfer efforts have begun with the submission of an abstract for a technical paper for the Oklahoma City Society of Petroleum Engineers meeting in March 2001.

Levels and source apportionment of volatile organic compounds in southwestern area of Mexico City.  

PubMed

Thirteen volatile organic compounds (VOCs) were quantified at three sites in southwestern Mexico City from July 2000 to February 2001. High concentrations of different VOCs were found at a Gasoline refueling station (GS), a Condominium area (CA), and at the University Center for Atmospheric Sciences (CAS). The most abundant VOCs at CA and CAS were propane, n-butane, toluene, acetylene and pentane. In comparison, at GS the most abundant were toluene, pentane, propane, n-butane, and acetylene. Benzene, a known carcinogenic compound had average levels of 28, 35 and 250ppbC at CAS, CA, and GS respectively. The main contributing sources of the measured VOCs at CA and CAS were the handling and management of LP (Liquid Propane) gas, vehicle exhaust, asphalt works, and use of solvents. At GS almost all of the VOCs came from vehicle exhaust and fuel evaporation, although components of LP gas were also present. Based on the overall results possible abatement strategies are discussed.

Evaluation of a Three-Dimensional Chemical Transport Model (PMCAMx) in the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

Atmospheric aerosols have adverse effects on human health, contribute to the visibility reduction and influence the energy balance of the planet. A three-dimensional chemical transport model (PMCAMx) (Gaydos et al., 2007) is used to simulate the particular matter (PM) mass composition distribution in the Mexico City Metropolitan Area (MCMA). PMCAMx uses the framework of CAMx (ENVIRON, 2002) modelling the processes of horizontal and vertical advection, horizontal and vertical dispersion, wet and dry deposition, and gas-phase chemistry. In addition to the above, PMCAMx includes three detailed aerosol modules: inorganic aerosol growth (Gaydos et al., 2003; Koo et al., 2003a), aqueous-phase chemistry (Fahey and Pandis, 2001), and secondary organic aerosol formation and growth (Koo et al., 2004). The aerosol thermodynamic model ISORROPIA has been improved as it now simulates explicitly the chemistry of Ca, Mg, and K salts and is linked to PMCAMx. The hybrid approach (Koo et al., 2003b) for modelling aerosol dynamics is applied in order to accurately simulate the inorganic components in coarse mode. This approach assumes that the smallest particles are in equilibrium while the condensation/evaporation equation is solved for the larger ones. The new CMU organic aerosol model, which is based on the splitting of the organic aerosol volatility range in discrete bins, is also used. The model predictions are evaluated against the PM and vapour concentration measurements from the MCMA-2003 Campaign (Molina et al., 2007).

Chemical evolution of volatile organic compounds in the outflow of the Mexico City Metropolitan area  

NASA Astrophysics Data System (ADS)

The volatile organic compound (VOC) distribution in the Mexico City Metropolitan Area (MCMA) and its evolution as it is uplifted and transported out of the MCMA basin was studied during the 2006 MILAGRO/MIRAGE-Mex field campaign. The results show that in the morning hours in the city center, the VOC distribution is dominated by non-methane hydrocarbons (NMHCs) but with a substantial contribution from oxygenated volatile organic compounds (OVOCs), predominantly from primary emissions. Alkanes account for a large part of the NMHC distribution in terms of mixing ratios. In terms of reactivity, NMHCs also dominate overall, especially in the morning hours. However, in the afternoon, as the boundary layer lifts and air is mixed and aged within the basin, the distribution changes as secondary products are formed. The WRF-Chem (Weather Research and Forecasting with Chemistry) model and MOZART (Model for Ozone and Related chemical Tracers) were able to approximate the observed MCMA daytime patterns and absolute values of the VOC OH reactivity. The MOZART model is also in agreement with observations showing that NMHCs dominate the reactivity distribution except in the afternoon hours. The WRF-Chem and MOZART models showed higher reactivity than the experimental data during the nighttime cycle, perhaps indicating problems with the modeled nighttime boundary layer height. A northeast transport event was studied in which air originating in the MCMA was intercepted aloft with the Department of Energy (DOE) G1 on 18 March and downwind with the National Center for Atmospheric Research (NCAR) C130 one day later on 19 March. A number of identical species measured aboard each aircraft gave insight into the chemical evolution of the plume as it aged and was transported as far as 1000 km downwind; ozone was shown to be photochemically produced in the plume. The WRF-Chem and MOZART models were used to examine the spatial extent and temporal evolution of the plume and to help interpret the observed OH reactivity. The model results generally showed good agreement with experimental results for the total VOC OH reactivity downwind and gave insight into the distributions of VOC chemical classes. A box model with detailed gas phase chemistry (NCAR Master Mechanism), initialized with concentrations observed at one of the ground sites in the MCMA, was used to examine the expected evolution of specific VOCs over a 1-2 day period. The models clearly supported the experimental evidence for NMHC oxidation leading to the formation of OVOCs downwind, which then become the primary fuel for ozone production far away from the MCMA.

Small-area estimation of the probability of toxocariasis in New York City based on sociodemographic neighborhood composition.  

PubMed

Toxocariasis is increasingly recognized as an important neglected infection of poverty (NIP) in developed countries, and may constitute the most important NIP in the United States (US) given its association with chronic sequelae such as asthma and poor cognitive development. Its potential public health burden notwithstanding, toxocariasis surveillance is minimal throughout the US and so the true burden of disease remains uncertain in many areas. The Third National Health and Nutrition Examination Survey conducted a representative serologic survey of toxocariasis to estimate the prevalence of infection in diverse US subpopulations across different regions of the country. Using the NHANES III surveillance data, the current study applied the predicted probabilities of toxocariasis to the sociodemographic composition of New York census tracts to estimate the local probability of infection across the city. The predicted probability of toxocariasis ranged from 6% among US-born Latino women with a university education to 57% among immigrant men with less than a high school education. The predicted probability of toxocariasis exhibited marked spatial variation across the city, with particularly high infection probabilities in large sections of Queens, and smaller, more concentrated areas of Brooklyn and northern Manhattan. This investigation is the first attempt at small-area estimation of the probability surface of toxocariasis in a major US city. While this study does not define toxocariasis risk directly, it does provide a much needed tool to aid the development of toxocariasis surveillance in New York City. PMID:24918785

Violence-related firearm deaths among residents of metropolitan areas and cities---United States, 2006--2007.  

PubMed

Violence-related firearm deaths remain an important public health concern in the United States. During 2006--2007, a total of 25,423 firearm homicides and 34,235 firearm suicides occurred among U.S. residents. These national totals include 4,166 firearm homicides and 1,446 firearm suicides among youths aged 10--19 years; the rate of firearm homicides among youths slightly exceeded the rate among persons of all ages. This report presents statistics on firearm homicides and firearm suicides for major metropolitan areas and cities, with an emphasis on youths aged 10--19 years in recognition of the importance of early prevention efforts. It integrates analyses conducted by CDC in response to requests for detailed information, arising from a heightened focus on urban violence by the media, the public, and policymakers over the past year. Firearm homicides and suicides and annual rates were tabulated for the 50 largest U.S. metropolitan statistical areas (MSAs) and their central cities for 2006--2007, using data from the National Vital Statistics System and the U.S. Census Bureau. Firearm homicide rates in approximately two thirds of the MSAs exceeded the national rate, and 86% of cities had rates higher than those of their MSAs. The youth firearm homicide rate exceeded the all-ages rate in 80% of the MSAs and in 88% of the cities. Firearm suicide rates in just over half of the MSAs were below the national rate, and 55% of cities had rates below those of their MSAs. Youth firearm suicide rates in the MSAs and cities were collectively low compared with all-ages rates. Such variations in firearm homicide and firearm suicide rates, with respect to both urbanization and age, should be considered in the continuing development of prevention programs directed at reducing firearm violence.

Small area estimates reveal high cigarette smoking prevalence in low-income cities of Los Angeles county.  

PubMed

Los Angeles County has among the lowest smoking rates of large urban counties in the USA. Nevertheless, concerning disparities persist as high smoking prevalence is found among certain subgroups. We calculated adult smoking prevalence in the incorporated cities of Los Angeles County in order to identify cities with high smoking prevalence. The prevalence was estimated by a model-based small area estimation method with utilization of three data sources, including the 2007 Los Angeles County Health Survey, the 2000 Census, and the 2007 Los Angeles County Population Estimates and Projection System. Smoking prevalence varied considerably across cities, with a more than fourfold difference between the lowest (5.3%) and the highest prevalence (21.7%). Higher smoking prevalence was generally found in socioeconomically disadvantaged cities. The disparities identified here add another layer of data to our knowledge of the health inequities experienced by low-income urban communities and provide much sought data for local tobacco control. Our study also demonstrates the feasibility of providing credible local estimates of smoking prevalence using the model-based small area estimation method. PMID:21947903

Facies architecture of the Bluejacket Sandstone in the Eufaula Lake area, Oklahoma: Implications for the reservoir characterization of the Bartlesville Sandstone  

SciTech Connect

Outcrop studies of the Bluejacket Sandstone (Middle Pennsylvanian) provide significant insights to reservoir architecture of the subsurface equivalent Bartlesville Sandstone. Quarry walls and road cuts in the Lake Eufaula area offer excellent exposures for detailed facies architectural investigations using high-precision surveying, photo mosaics. Directional minipermeameter measurements are being conducted. Subsurface studies include conventional logs, borehole image log, and core data. Reservoir architectures are reconstructed in four hierarchical levels: multi-storey sandstone, i.e. discrete genetic intervals; individual discrete genetic interval; facies within a discrete genetic interval; and lateral accretion bar deposits. In both outcrop and subsurface, the Bluejacket (Bartlesville) Sandstone comprises two distinctive architectures: a lower braided fluvial and an upper meandering fluvial. Braided fluvial deposits are typically 30 to 80 ft thick, and are laterally persistent filling an incised valley wider than the largest producing fields. The lower contact is irregular with local relief of 50 ft. The braided-fluvial deposits consist of 100-400-ft wide, 5-15-ft thick channel-fill elements. Each channel-fill interval is limited laterally by an erosional contact or overbank deposits, and is separated vertically by discontinuous mudstones or highly concentrated mudstone interclast lag conglomerates. Low-angle parallel-stratified or trough cross-stratified medium- to coarse-grained sandstones volumetrically dominate. This section has a blocky well log profile. Meandering fluvial deposits are typically 100 to 150 ft thick and comprise multiple discrete genetic intervals.

Feasibility study of heavy oil recovery in the Midcontinent region (Kansas, Missouri, Oklahoma)  

SciTech Connect

This report is one of a series of publications assessing the feasibility/constraints of increasing domestic heavy oil production. Each report covers a select area of the United States. The Midcontinent (Kansas, Nssouri, Oklahoma) has produced significant oil, but contrary to early reports, the area does not contain the huge volumes of heavy oil that, along with the development of steam and in situ combustion as oil production technologies, sparked the area`s oil boom of the 1960s. Recovery of this heavy oil has proven economically unfeasible for most operators due to the geology of the formations rather than the technology applied to recover the oil. The geology of the southern Midcontinent, as well as results of field projects using thermal enhanced oil recovery (TEOR) methods to produce the heavy oil, was examined based on analysis of data from secondary sources. Analysis of the performance of these projects showed that the technology recovered additional heavy oil above what was produced from primary production from the consolidated, compartmentalized, fluvial dominated deltaic sandstone formations in the Cherokee and Forest City basins. The only projects producing significant economic and environmentally acceptable heavy oil in the Midcontinent are in higher permeability, unconsolidated or friable, thick sands such as those found in south-central Oklahoma. There are domestic heavy oil reservoirs in other sedimentary basins that are in younger formations, are less consolidated, have higher permeability and can be economically produced with current TEOR technology. Heavy oil production from the carbonates of central and wester Kansas has not been adequately tested, but oil production is anticipated to remain low. Significant expansion of Midcontinent heavy oil production is not anticipated because the economics of oil production and processing are not favorable.

Culture and self: are there within-culture differences in self between metropolitan areas and regional cities?  

PubMed

Although differences in self-conception across cultures have been well researched, regional differences within a culture have escaped attention. The present study examined individual, relational, and collective selves, which capture people's conceptions of themselves in relation to their goals, significant others, and in groups, comparing Australians and Japanese participants living in regional cities and metropolitan areas. Culture, gender, and urbanism were found to be related to individual, relational, and collective selves, respectively. Australians emphasized individual self more than Japanese, women stressed relational self more than men, and residents in regional cities regarded collective self as more important than their counterparts in metropolitan areas. These findings provide support for the tripartite division of the self and suggest a need to construct a culture theory that links self and societal processes. PMID:15200690

Assessment of impacts produced by anthropogenic sources in a little city near an important industrial area (Modugno, Southern Italy).  

PubMed

An annual monitoring campaign of VOCs, consisting of twelve sampling periods, was carried out from June 2008 to June 2009 in Modugno, a city located in the Apulia region (Southern Italy), in order to assess the urban air quality, identify the main emission sources, and quantify the cancer and no-cancer risk attributable to inhalation exposures. Monitoring, carried out by using the Radiello diffusive samplers, was conducted in eleven sampling sites throughout the city taking into account the traffic density and the architecture of the city. From the study of the data, it was found that, among all considered VOCs, benzene, toluene, ethylbenzene, and xylenes (BTEX) are the pollutants at higher concentration. The analysis of VOC concentrations, the study of the topography of the city, and the use of different diagnostic ratios between the BTEX species showed that the vehicular traffic emissions were the predominant source of VOCs in the urban area of Modugno. Despite that the annual concentration of benzene is lower than the regulatory limit, the estimation of cancer risk showed that the global lifetime cancer risk attributed to the investigated VOC exposure was not negligible and therefore should be taken into account in future regulatory approaches.

Drought impacts in the New York City metropolitan area: A comparison of impacts between 1995 and other recent droughts  

SciTech Connect

This study is intended to provide information on drought impact on the major cities in the northeastern US. The effects of the 1995 drought on water resources, electric utilities, agriculture, forestry, recreation, and retail sales are analyzed for New York City and surrounding counties. Water resource related impacts associated with the most recent drought are also compared with those that occurred during the prolonged mid-1960s drought and shorter drought periods in the early and mid-1980s. The assessment of drought impacts from the 1995 drought in the New York metropolitan area showed the influence of this drought on water resources to be relatively minor with the exception of some show ground water problems and reduced flow on the Hudson River. There were also negative impacts on non-irrigated agriculture and fire prevention/control operations. In general, these impacts were relatively minor in comparison with prior droughts. Based on the Palmer Drought Severity Index (PDSI) and precipitation deficit, a temporal comparison of droughts in New York City with respect to water supply indicates a general delay in the occurrence of drought impacts and responses. This may be a result of improved efforts to promote water conservation within the city or a reflection of increased reservoir capacity coupled with a declining urban population. 6 refs., 4 figs.

USGS Publications Warehouse

Years of sediment accumulation and dry conditions in recent years have led to the decline of water levels and capacities for many water-supply reservoirs in Missouri, and have caused renewed interest in modernizing outdated area/capacity tables for these reservoirs. The U.S. Geological Survey, in cooperation with the Missouri Department of Natural Resources, surveyed the bathymetry of the four water-supply reservoirs used by the city of Cameron, Missouri, in July 2013. The data were used to provide water managers with area/capacity tables and bathymetric maps of the reservoirs at the time of the surveys.

Quantification of metal loading to Silver Creek through the Silver Maple Claims area, Park City, Utah, May 2002  

USGS Publications Warehouse

The Silver Maple Claims area along Silver Creek, near Park City, Utah, is administered by the Bureau of Land Management. To quantify possible sources of elevated zinc concentrations in Silver Creek that exceed water-quality standards, the U.S. Geological Survey conducted a mass-loading study in May 2002 along a 1,400-meter reach of Silver Creek that included the Silver Maple Claims area. Additional samples were collected upstream and downstream from the injection reach to investigate other possible sources of zinc and other metals to the stream. Many metals were investigated in the study, but zinc is of particular concern for water-quality standards. The total loading of zinc along the study reach from Park City to Wanship, Utah, was about 49 kilograms per day. The Silver Maple Claims area contributed about 38 percent of this load. The Silver Creek tailings discharge pipe, which empties just inside the Silver Maple Claims area, contributed more than half the load of the Silver Maple Claims area. Substantial zinc loads also were added to Silver Creek downstream from the Silver Maple Claims area. Ground-water discharge upstream from the waste-water treatment plant contributed 20 percent of the total zinc load, and another 17 percent was contributed near the waste-water treatment plant. By identifying the specific areas where zinc and other metal loads are contributed to Silver Creek, it is possible to assess the needs of a remediation plan. For example, removing the tailings from the Silver Maple Claims area could contribute to lowering the zinc concentration in Silver Creek, but without also addressing the loading from the Silver Creek tailings discharge pipe and the ground-water discharge farther downstream, the zinc concentration could not be lowered enough to meet water-quality standards. Additional existing sources of zinc loading downstream from the Silver Maple Claims area could complicate the process of lowering zinc concentration to meet water-quality standards.

Environmental Characteristics and Geographic Information System Applications for the Development of Nutrient Thresholds in Oklahoma Streams  

USGS Publications Warehouse

The U.S.Environmental Protection Agency has developed nutrient criteria using ecoregions to manage and protect rivers and streams in the United States. Individual states and tribes are encouraged by the U.S. Environmental Protection Agency to modify or improve upon the ecoregion approach. The Oklahoma Water Resources Board uses a dichotomous process that stratifies streams using environmental characteristics such as stream order and stream slope. This process is called the Use Support Assessment Protocols, subchapter15. The Use Support Assessment Protocols can be used to identify streams threatened by excessive amounts of nutrients, dependant upon a beneficial use designation for each stream. The Use Support Assessment Protocols, subchapter 15 uses nutrient and environmental characteristic thresholds developed from a study conducted in the Netherlands, but the Oklahoma Water Resources Board wants to modify the thresholds to reflect hydrologic and ecological conditions relevant to Oklahoma streams and rivers. Environmental characteristics thought to affect impairment from nutrient concentrations in Oklahoma streams and rivers were determined for 798 water-quality sites in Oklahoma. Nutrient, chlorophyll, water-properties, and location data were retrieved from the U.S. Environmental Protection Agency STORET database including data from the U.S. Geological Survey, Oklahoma Conservation Commission, and Oklahoma Water Resources Board. Drainage-basin area, stream order, stream slope, and land-use proportions were determined for each site using a Geographic Information System. The methods, procedures, and data sets used to determine the environmental characteristics are described.

Robust Principal Component Analysis and Geographically Weighted Regression: Urbanization in the Twin Cities Metropolitan Area of Minnesota  

PubMed Central

In this paper, we present a hybrid approach, robust principal component geographically weighted regression (RPCGWR), in examining urbanization as a function of both extant urban land use and the effect of social and environmental factors in the Twin Cities Metropolitan Area (TCMA) of Minnesota. We used remotely sensed data to treat urbanization via the proxy of impervious surface. We then integrated two different methods, robust principal component analysis (RPCA) and geographically weighted regression (GWR) to create an innovative approach to model urbanization. The RPCGWR results show significant spatial heterogeneity in the relationships between proportion of impervious surface and the explanatory factors in the TCMA. We link this heterogeneity to the “sprawling” nature of urban land use that has moved outward from the core Twin Cities through to their suburbs and exurbs. PMID:23814454

Water Flow in the High Plains Aquifer in Northwestern Oklahoma  

USGS Publications Warehouse

The High Plains is a major agricultural area, supported primarily by water from the High Plains aquifer, which is used to irrigate wheat and corn and to raise cattle and swine. The U.S. Geological Survey (USGS) and the Oklahoma Water Resources Board (OWRB) began a study of the High Plains aquifer in 1996. One purpose of the study was to develop a ground-water flow model that the OWRB could use to allocate the amount of water withdrawn from the a aquifer. The study area in Oklahoma covers all or parts of Beaver, Cimarron, Dewey, Ellis, Harper, Texas, and Woodward Counties. To provide appropriate hydrologic boundaries for the ground-water flow model, the study area was expanded to include parts of Colorado, Kansas, New Mexico, and Texas.

Dengue Outbreaks in High-Income Area, Kaohsiung City, Taiwan, 2003-2009  

PubMed Central

Kaohsiung City, a modern metropolis of 1.5 million persons, has been the focus of dengue virus activity in Taiwan for several decades. The aim of this study was to provide a temporal and spatial description of dengue virus epidemiology in Kaohsiung City by using data for all laboratory-confirmed dengue cases during 2003–2009. We investigated age- and sex-dependent incidence rates and the spatiotemporal patterns of all cases confirmed through passive or active surveillance. Elderly persons were at particularly high risk for dengue virus–related sickness and death. Of all confirmed cases, ?75% were detected through passive surveillance activities; case-patients detected through active surveillance included immediate family members, neighbors, and colleagues of confirmed case-patients. Changing patterns of case clustering could be due to the effect of unmeasured environmental and demographic factors. PMID:23017369

Cumulative influences of a small city and former mining activities on the sediment quality of a subtropical estuarine protected area.  

PubMed

This study aimed to evaluate the sediment quality in the estuarine protected area known as Cananéia-Iguape-Peruíbe (CIP-PA), located on the southeastern coast of Brazil. The study was designed considering possible negative effects induced by the city of Cananéia on the sediment quality of surrounding areas. This evaluation was performed using chemical and ecotoxicological analyses. Sediments were predominantly sandy, with low CaCO3 contents. Amounts of organic matter varied, but higher contents occurred closer to the city, as well as did Fe and Total Recoverable Oils and Greases (TROGs) concentrations. Contamination by Cd and Cu was revealed in some samples, while concentrations of Zn were considered low. Chronic toxicity was detected in all tested sediments and acute toxicity occurred only in sediments collected near the city. The principal component analysis (PCA) revealed an association among Cd, Cu, Fe, TROG, fines, organic matter, CaCO3, and chronic toxicity, whereas acute toxicity was found to be associated with Zn and mud. However, because Zn levels were low, acute toxicity was likely due to a contaminant that was not measured. Results show that there is a broad area within the CIP-PA that is under the influence of mining activities (chronic toxicity, moderate contamination by metals), whereas poorer conditions occur closer to Cananéia (acute toxicity); thus, the urban area seems to constitute a relevant source of contaminants for the estuarine complex. These results show that contamination is already capable of producing risks for the local aquatic biota, which suggests that the CIP-PA effectiveness in protecting estuarine biota may be threatened.

Class 1 overview of cultural resources for the Western Area Power Administration Salt Lake City Area Integrated Projects electric power marketing environmental impact statement  

SciTech Connect

Argonne National Laboratory conducted an inventory of known archaeological and historic sites in areas that could be affected by the hydropower operation alternatives under analysis in the power marketing environmental impact statement for the Western Area Power Administration`s Salt Lake City Area Integrated Projects. The study areas included portions of the Green River (Flaming Gorge Dam to Cub Creek) in Utah and Colorado and the Gunnison River (Blue Mesa Reservoir to Crystal Dam) in Colorado. All previous archaeological surveys and previously recorded prehistoric and historic sites, structures, and features were inventoried and plotted on maps (only survey area maps are included in this report). The surveys were classified by their level of intensity, and the sites were classified according to their age, type, and contents. These data (presented here in tabular form) permit a general assessment of the character and distribution of archaeological remains in the study areas, as well as an indication of the sampling basis for such an assessment. To provide an adequate context for the descriptions of the archaeological and historic sites, this report also presents overviews of the environmental setting and the regional prehistory, history, and ethnography for each study area.

Changes in flow in the upper North Canadian river basin of western Oklahoma, pre-development to 2000  

USGS Publications Warehouse

Water levels have declined in the southern part of the High Plains aquifer of the central USA since the mid-1960s in response to extensive irrigation development. The North Canadian River originates in western Oklahoma, and most of the basin is underlain by the High Plains aquifer. Average river flow in the headwaters near Guymon, Oklahoma, has decreased from about 0.9 m3/s before 1970 to near zero at present. Canton Lake, on the North Canadian River near Seiling, about 250 km downstream from Guymon, is a source of water supply for Oklahoma City. Precipitation data and streamflow data for gages upstream from Canton Lake were divided into an "early" period ending in 1971 and a "recent" period that begins in 1978. The early period represents conditions before ground-water levels had declined appreciably in the High Plains aquifer, and the recent period reflects the current condition, including the effects of storage reservoirs. Tests for trend and comparisons of flows between the early and recent periods show that the total annual volume of flow and the magnitudes of instantaneous annual peak discharges measured at most locations in the North Canadian River basin have decreased. Precipitation records for the area, however, show no corresponding changes. The decreases in average annual flow, expressed as a percentage of the average flows for the early period, ranged from 91 percent near Guymon to 37 percent near Canton Lake. A major contributing factor in the decreased flows appears to be the large declines in water levels in the High Plains aquifer.

Small area estimation of obesity prevalence and dietary patterns: a model applied to Rio de Janeiro city, Brazil.  

PubMed

We propose the use of previously developed small area estimation techniques to monitor obesity and dietary habits in developing countries and apply the model to Rio de Janeiro city. We estimate obesity prevalence rates at the Census Tract through a combinatorial optimization spatial microsimulation model that matches body mass index and socio-demographic data in Brazil's 2008-9 family expenditure survey with Census 2010 socio-demographic data. Obesity ranges from 8% to 25% in most areas and affects the poor almost as much as the rich. Male and female obesity rates are uncorrelated at the small area level. The model is an effective tool to understand the complexity of the problem and to aid in policy design. PMID:24368257

Assessment of atmospheric metal pollution in the urban area of Mexico City, using Ficus benjamina as biomonitor.  

PubMed

Concentrations of vanadium, chromium, cobalt, nickel, copper, zinc, antimony, and lead were measured in Ficus benjamina leaves from the Mexico City urban area in order to assess their enrichment against background values. The instrumental analysis was performed using inductively coupled plasma mass spectrometry and the analytical method was tested using two certified reference materials from the National Institute of Standards and Technology (1547 Peach Leaves and 1573a Tomato Leaves). Enrichment factors were calculated, i.e., total to background concentration ratio, for each metal. Low enrichments of vanadium, cobalt, nickel, and copper (?2), and mild enrichments of chromium and zinc (4.4, 4.5 respectively) were found in the entire area; oppositely, high enrichments were assessed for antimony (28.6) and lead (17.2). However, results indicate that metal concentrations strongly depend on the specific urban sub-area. Increments of metals were attributed to natural, vehicular, and industrial sources. PMID:21437785

The Salt Lake City Area Office of the Western Area Power Administration (Western) markets electricity produced at hydroelectric facilities operated by the Bureau of Reclamation. The facilities are known collectively as the Salt Lake City Area Integrated Projects (SLCA/IP) and include dams equipped for power generation on the Green, Gunnison, Rio Grande, and Colorado rivers and on Deer and Plateau creeks in the states of Wyoming, Utah, Colorado, Arizona, and New Mexico. Of these facilities, only the Glen Canyon Unit, the Flaming Gorge Unit, and the Aspinall Unit (which includes Blue Mesa, Morrow Point, and Crystal dams;) are influenced by Western power scheduling and transmission decisions. The EIS alternatives, called commitment-level alternatives, reflect combinations of capacity and energy that would feasibly and reasonably fulfill Westerns firm power marketing responsibilities, needs, and statutory obligations. The viability of these alternatives relates directly to the combination of generation capability of the SLCA/IP with energy purchases and interchange. The economic and natural resource assessments in this environmental impact statement (EIS) include an analysis of commitment-level alternatives. Impacts of the no-action alternative are also assessed. Supply options, which include combinations of electrical power purchases and hydropower operational scenarios reflecting different operations of the dams, are also assessed. The EIS evaluates the impacts of these scenarios relative to socioeconomics, air resources, water resources, ecological resources, cultural resources, land use, recreation, and visual resources.

A benefit-cost analysis of retrofitting diesel vehicles with particulate filters in the Mexico City metropolitan area.  

PubMed

In the Mexico City metropolitan area, poor air quality is a public health concern. Diesel vehicles contribute significantly to the emissions that are most harmful to health. Harmful diesel emissions can be reduced by retrofitting vehicles with one of several technologies, including diesel particulate filters. We quantified the social costs and benefits, including health benefits, of retrofitting diesel vehicles in Mexico City with catalyzed diesel particulate filters, actively regenerating diesel particulate filters, or diesel oxidation catalysts, either immediately or in 2010, when capital costs are expected to be lower. Retrofit with either type of diesel particulate filter or an oxidation catalyst is expected to provide net benefits to society beginning immediately and in 2010. At current prices, retrofit with an oxidation catalyst provides greatest net benefits. However, as capital costs decrease, retrofit with diesel particulate filters is expected to provide greater net benefits. In both scenarios, retrofit of older, dirtier vehicles that circulate only within the city provides greatest benefits, and retrofit with oxidation catalysts provides greater health benefits per dollar spent than retrofit with particulate filters. Uncertainty about the magnitude of net benefits of a retrofit program is significant. Results are most sensitive to values used to calculate benefits, such as the concentration-response coefficient, intake fraction (a measure of exposure), and the monetary value of health benefits.

Monitoring of Heavy Metals Content in Soil Collected from City Centre and Industrial Areas of Misurata, Libya  

PubMed Central

The present paper deals with the assessment of heavy metals in soil and roadside dust around Misurata City Centre and industrial areas/roads in the period of October 2011–May 2012. The levels of Pb, Fe, Zn, Ni, Cd, Cr, and Cu in settled dust samples collected near small streets, playgrounds, gas stations and main streets in the Misurata Area have been determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES). Also, the levels of same heavy metals in industrial areas have been determined. Metal concentration trend variation was also discussed in relation with traffic density and other sources of fugitive emission around different sites on each road/area. The overall mean concentration for main streets was significantly higher (P < 0.05) than for other small streets, where Misurata has been the centre of fierce fighting and is located in a frontline battle zone in the Libyan war; therefore most of metal concentrations in surface soil in the fighting area Tripoli Street and Benghazi Street were higher than those from the other sites (outside fighting area).

Final report for "Characterization of Fine Particulate Matter (PM) and secondary PM Precursor Gases in the Mexico City Metropolitan Area"  

SciTech Connect

The objectives of this funded project were (a) to further analyze the data collected by our group and collaborators in Mexico City during the MCMA-2003 field campaign, with the goal of further our understanding of aerosol sources and processes; and (b) to deploy several advanced instruments, including the newly developed high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) and thermal-denuder (TD), during the MILAGRO/MAX-Mex/MCMA-2006 field campaign, and to analyze those data (together with the 2003 data) to provide additional insights on the formation and transformation of aerosols in the Mexico City area. These goals were addressed in collaboration with our project partners, MIT/Molina Center, and Aerodyne Research. Overall this project was very successful, resulting on 22+ journal papers including six “highly cited papers” and three papers that are the most cited in their respective journals (out of several thousand papers) since the year in which they were published. Multiple discoveries, such as the the underestimation of SOA in urban areas even for short photochemical ages, the demonstration that urban POA is of similar or higher volatility than urban SOA, and the first analysis of organic aerosol elemental composition in real-time have been recently published. Several dozen presentations at major US and international conferences and seminars also acknowledged this grant.

Seasonal ion characteristics of fine and coarse particles from an urban residential area in a typical industrial city  

NASA Astrophysics Data System (ADS)

This study investigated seasonal ion variation and correlation characteristics in size-fractionated particles collected for four seasons using an eight-stage cascade impactor sampler from an urban residential area in the largest industrial city, Korea. The identified ionic species accounted for 47.4, 52.5, 35.8, and 44.5% of PM1.1, PM2.1, PM10 - 2.1, and PM10 (PM2.1 + PM10 - 2.1), respectively. Sulfate (SO42 -) was the most abundant species and had the highest relative concentrations of both fine and coarse particles in summer. However, nitrate (NO3-) and ammonium (NH4+) showed the highest fractions in fine particle mass concentration in winter. NH4+ showed the highest mass fraction in coarse particles in spring. The highest ratio of NO3/SO42 - in fine particle in winter was due to the decreased sulfate and increased nitrate formation by low winter temperature. Most ions, such as SO42 -, NH4+, K+, Cl- and NO3-, accumulate in fine particles (PM2.1); while the concentrations of Na+, Ca2 + and Mg2 + were greater in the coarse particles (PM10 - 2.1). In the cluster analyses of the ion components, road and soil dust, secondary aerosols and sea salt were shown to be possible major airborne PM sources in residential areas of the industrial city.

PIXE and XRF analysis of atmospheric aerosols from a site in the West area of Mexico City  

NASA Astrophysics Data System (ADS)

Due to geographical factors, most of the Metropolitan Area of Mexico City features, on average, similar heights above the sea level, climate, wind speed and direction, with very uniform pollution degrees in most of the frequently studied sites. A site with different characteristics, Cuajimalpa de Morelos, was studied. It is located to the West of the urban area at 2760 m above sea level, in contrast to other sites (2240 m). Here, the wind is mostly directed towards the center of the city. Then, the site should not be affected by pollutants from the Northern/Northeastern industrial zones, so lower aerosol concentrations are expected. In this work, the elemental composition of coarse (PM10-2.5) and fine (PM2.5) fractions of atmospheric aerosol samples collected in Cuajimalpa is studied. The sampling period covered the cold-dry season in 2004-2005 (December 1st, 2004 to March 31, 2005), exposing polycarbonate filters with a Stacked Filter Unit of the Gent design along 24 h, every two days. The samples were analyzed with Particle Induced X-ray Emission (PIXE) and X-ray Fluorescence (XRF), to obtain elemental concentrations. The EPA code UNMIX was used to determine the number of possible influencing polluting sources, which were then identified through back-trajectory simulations with the HYSPLIT modeling software. Four sources (mostly related to soil) were found in the coarse fraction, while the fine fraction presented three main sources (fuel oil, industry and biomass burning).

A comparison of the speech patterns and dialect attitudes of Oklahoma  

NASA Astrophysics Data System (ADS)

The lexical dialect usage of Oklahoma has been well-studied in the past by the Survey of Oklahoma Dialects, but the acoustic speech production of the state has received little attention. Apart from two people from Tulsa and two people from Oklahoma City that were interviewed for the Atlas of North American English, no other acoustic work has been performed within the state. This dissertation begins to fill in these gaps by presenting twelve respondents interviewed by the Research on Dialects of English in Oklahoma (RODEO) project. For each speaker, a brief biography is given, including some of their regional and speech attitudes of Oklahoma. Then acoustic data from a wordlist and reading task are presented and compared. Analysis will consider plots of each speaker's vowel system as a whole, and will also examine many environments in isolation. These environments were chosen for their likely presence in Oklahoma, and include such dialect features as the Southern Shift, the pin/pen merger, the caught/cot merger, monophthongization of the PRICE vowel, and neutralization of tense vowels before /l./ After considering each respondent separately, some of their results will be pooled together to give a preliminary sense of the state of dialect within Oklahoma. Demographic variables such as age, gender, and urban/rural upbringing will be related to speakers' attitudes and acoustic production. This will serve two goals - first, to compare modern-day production to the findings of previous scholars, and second, to suggest a dialect trajectory for the state that could be studied further in additional research.

This paper analyzes the wealth of species, relative abundance, seasonal fluctuation, and nocturnal activity of sandflies. The field survey was conducted in a "capoeira" (secondary forest) area in the county of Paço do Lumiar, Maranhão, where cutaneous and transmission of visceral leishmaniasis frequently occurs. Sandflies were captured by CDC-type light traps from 6:00 PM to 6:00 AM, once a month, from March 1997 to February 1998. A total of 489 specimens were collected (251 males and 238 females), distributed among 10 species: Lutzomyia antunesi (45.19%), Lutzomyia whitmani (29.4%), Lutzomyia longipalpis (7.56%), Lutzomyia sordelli (6.34%), Lutzomyia flaviscutellata (4.5%), Brumptomyia avellari (4.09%), Lutzomyia evandroi (1.85%), Lutzomyia umbratilis (0.61%), Lutzomyia corossoniensis (0.41%), and Lutzomyia trispinosa (0.41%). The sandflies were present year round, with higher abundance during the rainy season. They were present in all intervals studied, with the highest frequency between 12:00 PM and 1:00 AM (31%).

Good water governance, has been regarded as a sine qua non for improving the management of world water resources. Stakeholder participation is considered an important precondition for improving water governance. This paper reports on how it is being implemented in urban areas in Zimbabwe by studying how this is being undertaken in the city of Harare. The study was not designed to generate generalisable findings but to gain insights into the salient features of water governance in the urban areas. Three areas of investigation were chosen for analysis; whether water shaped the political agenda as expressed in local elections; perceptions and actions of the different actors and information about new water institutions. There was some degree of stakeholder participation, which, however, was compromised by the fact that it was uncoordinated, involved a few stakeholders (it excluded the generality of the residents) and tended to occur outside the designated formal channels. Interference from central government was another problem. It can be concluded that improving governance of water management in Zimbabwe’s urban areas faces more challenges than in the rural areas. For example unlike their rural counterparts urban residents were not considered as stakeholders in their own right.

MISR Scans the Texas-Oklahoma Border  

NASA Technical Reports Server (NTRS)

These MISR images of Oklahoma and north Texas were acquired on March 12, 2000 during Terra orbit 1243. The three images on the left, from top to bottom, are from the 70-degree forward viewing camera, the vertical-viewing (nadir) camera, and the 70-degree aftward viewing camera. The higher brightness, bluer tinge, and reduced contrast of the oblique views result primarily from scattering of sunlight in the Earth's atmosphere, though some color and brightness variations are also due to differences in surface reflection at the different angles. The longer slant path through the atmosphere at the oblique angles also accentuates the appearance of thin, high-altitude cirrus clouds.

On the right, two areas from the nadir camera image are shown in more detail, along with notations highlighting major geographic features. The south bank of the Red River marks the boundary between Texas and Oklahoma. Traversing brush-covered and grassy plains, rolling hills, and prairies, the Red River and the Canadian River are important resources for farming, ranching, public drinking water, hydroelectric power, and recreation. Both originate in New Mexico and flow eastward, their waters eventually discharging into the Mississippi River.

A smoke plume to the north of the Ouachita Mountains and east of Lake Eufaula is visible in the detailed nadir imagery. The plume is also very obvious at the 70-degree forward view angle, to the right of center and about one-fourth of the way down from the top of the image.

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

300 Area process sewer piping upgrade and 300 Area treated effluent disposal facility discharge to the City of Richland Sewage System, Hanford Site, Richland, Washington  

SciTech Connect

The U.S. Department of Energy (DOE) is proposing to upgrade the existing 300 Area Process Sewer System by constructing and operating a new process sewer collection system that would discharge to the 300 Area Treated Effluent Disposal Facility. The DOE is also considering the construction of a tie-line from the TEDF to the 300 Area Sanitary Sewer for discharging the process wastewater to the City of Richland Sewage System. The proposed action is needed because the integrity of the old piping in the existing 300 Area Process Sewer System is questionable and effluents might be entering the soil column from leaking pipes. In addition, the DOE has identified a need to reduce anticipated operating costs at the new TEDF. The 300 Area Process Sewer Piping Upgrade (Project L-070) is estimated to cost approximately $9.9 million. The proposed work would involve the construction and operation of a new process sewer collection system. The new system would discharge the effluents to a collection sump and lift station for the TEDF. The TEDF is designed to treat and discharge the process effluent to the Columbia River. The process waste liquid effluent is currently well below the DOE requirements for radiological secondary containment and is not considered a RCRA hazardous waste or a State of Washington Hazardous Waste Management Act dangerous waste. A National Pollutant Discharge Elimination, System (NPDES) permit has been obtained from the U.S. Environmental Protection Agency for discharge to the Columbia River. The proposed action would upgrade the existing 300 Area Process Sewer System by the construction and operation of a new combined gravity, vacuum, and pressurized process sewer collection system consisting of vacuum collection sumps, pressure pump stations, and buried polyvinyl chloride or similar pipe. Two buildings would also be built to house a main collection station and a satellite collection station.

Sustainable sanitation systems for low income urban areas - A case of the city of Bulawayo, Zimbabwe  

NASA Astrophysics Data System (ADS)

Lack of basic sanitation systems threaten environmental and human health in low income urban communities. In 2005, the Government of Zimbabwe carried out a cleanup exercise in urban areas involving the destruction of illegal structures which left many people homeless. As a solution to this problem, the government embarked on an extensive housing construction exercise on unserviced land; the ‘Garikai/Hlalani Kuhle’ development programme. The objective of this paper was to investigate the sanitation status in one such area (Cowdray Park Extension, Bulawayo) and determine a sustainable sanitation system for the improved collection of wastewater from the unserviced low income urban area. The study was carried out between October 2010 and February 2011. The sanitation status as well as the residents’ preferences for improved sanitation and the economic set up of the community for the study area was determined through use of questionnaires to the residents. The local authority was then consulted to recommend sanitation facilities and system for the area that met regulatory requirements. A literature study identified sanitation options that were applicable to low income and high density urban areas. The baseline survey found that 61% of the people in the study area lacked sanitation facilities and practiced open defecation. The majority of the residents (70%) preferred ‘flush and discharge’ system sanitation facilities, which was in line with the local council’s requirements. On-site sanitation options were found not to be feasible as per the council regulations and the findings of the literature study, for areas with a high density of houses. Therefore a sewerage system was designed using the conventional sewerage design approach as well as the simplified sewerage design approach in order to determine the collection system that would best meet the needs of the community. In conclusion, the community was in dire need of a sanitation system and a waterborne offsite sanitation system was found to be a feasible option. The simplified sewerage system was found to deliver the same hydraulic benefits for collecting wastewater as the conventional but was 33% cheaper to construct and hence more affordable for the community. It was recommended that stringent environmental monitoring of the sanitation system be put in place to minimise any potential environmental impacts.

Acanthamoeba spp. in domestic tap water in houses of contact lens wearers in the metropolitan area of Mexico City.  

PubMed

A survey was carried out in the metropolitan area of Mexico City to determine the presence of Acanthamoeba in the tap water of houses of contact lens wearers. Water samples were taken from the mains water entry, bathroom sinks and storage containers (roof tanks, cisterns) of 27 houses; and from the solution contained in the contact lens cases. Samples were filtered and cultured onto NNE medium. The isolates were identified based on their morphological features and pathogenicity. Total and fecal coliforms, water temperature, pH, dissolved oxygen and residual free-chlorine were measured by standard methods. Forty five isolates of Acanthamoeba from 200 water samples were obtained. The highest number of amoebae was isolated from cisterns and roof tanks. Most Acanthamoeba isolates were non-pathogenic, however, their presence in tap water is a potential hazard since some species can cause Acanthamoeba keratitis and granulomatous amoebic encephalitis.

This is your brain on sports. Measuring concussions in high school athletes in the Twin Cities metropolitan area.  

PubMed

Concussions can have a negative impact on students' ability to perform in the classroom as well as on their health and well-being. Therefore, timely treatment is especially important. To better understand the scope of the problem in Minnesota, the Minnesota Department of Health piloted an online sports-related concussion reporting system in 36 public high schools in the Twin Cities metropolitan area. In the 2013-2014 academic year, 730 concussions were reported to our system from certified athletic trainers working with those schools, with one out of every 100 athletes sustaining concussions. From this, we estimated that 2,974 sports-related concussions occurred among high school athletes statewide. This information is useful for evaluating and guiding prevention efforts and for informing clinicians on how to treat concussions. PMID:25282771

Business establishment mobility behavior in urban areas: a microanalytical model for the City of Hamilton in Ontario, Canada  

NASA Astrophysics Data System (ADS)

We present a microanalytical firm mobility model for the City of Hamilton, Canada, developed with data from the Statistics Canada Business Register. Contributing to the scarce literature on firm migration behavior, we explore and model the determinants of mobility among small and medium size firms who retained less than 200 employees between 1996 and 1997. Our exploratory results suggest that short distance moves are more common and tend to occur among smaller firms. Econometric modeling results support these assertions and indicate that the willingness to move can be explained by a firm’s internal characteristics (e.g. age, size, growth and industry type) as well as location factors related to the urban environment where the firm is located. The modeling results will serve as input for the development of an agent-based firmographic decision support system that can be used to inform the planning process in the study area.

Atmospheric aerosol and gaseous pollutant concentrations in Bucharest area using first datasets from the city AQ monitoring network  

NASA Astrophysics Data System (ADS)

City of Bucharest is the largest and most populated (about 2.8 million inhabitants) city in the Romanian Plain and encounters environmental problems and meteorology typical for several cities in southeastern Europe. City environment includes intense emissions arising from traffic (about 1 million cars per day), five thermo-electrical power-generation stations, that use both natural gas and oil derivatives for power generation and domestic heating, and from industrial sources (more than 800 small and medium plants). In the present work we performed an extensive analysis of the air pollution state for the Bucharest area (inside and outside the city) using filter measurement aerosol data PM10 and PM2.5. Data spanning over first year of continuous sampling (2005) were taken from the city Air Quality Monitoring Network, which consists of eight sampling stations: three industrial and two traffic, one EPA urban background, one suburban and one regional station located outside of Bucharest. The objective was to assess the PM10 recorded levels and their degree of compliance with the EU-legislated air quality standards and to provide a statistical investigation of the factors controlling seasonal and spatial variations of PM levels. PM10 relationships with other measured air pollutants (SO2, CO, NOx) and meteorological parameters (temperature, relative humidity, atmospheric pressure, wind velocity and direction) were investigated by statistical analysis. Back trajectory modeling and wind direction frequency distributions were used to identify the origin of the polluted air masses. Contribution of combustion (slopes) and non-combustion (intercepts) sources to PM10 recorded levels was quantified by linear analysis, for two seasonal periods: cold (15 October-14 April) and warm (15 April-14 October). PM10 and PM2.5 concentrations were compared with corresponding values in other European urban areas. Main conclusions are as follows: Traffic and industrial sites contribute to the PM10 urban background with about 86%; relative contribution of urban background to regional background is about 37%; Relatively low inter-sites correlation coefficients and no significant geographic differences between sites, more or less uniform traffic pattern suggests local sources may play an important role; PM10average and median values systematically exceed the limit value of 50 ?g/m3 at traffic and industrial sites; at background sites the PM10 are below 50?g/m3 but are higher that values at similar sites in Europe; CO and SO2 do not put serious problems relative to their limits values as NOx does; NOx shows a temporal variation with higher values during the cold season; All gaseous pollutants contribute to the PM10 levels but a significant inter-annual variation of this contribution seems not to be observed; Pollution level in Bucharest seems to be higher than in other European cities for traffic, industrial and suburban background sites; regional background in the larger area of Bucharest seems to be similar with the suburban background sites in other European sites. Seven pollution episodes were identified, from which only one in the cold season has been attributed to the long-range transport. During this episode PM10 levels varied between 161-205 ?g/m3 for all sites, the dominant wind direction was NE (10.2%), with an average wind speed of 1.6 m/s. This shows that local pollution sources seem to have more impact on AQ than the long-range transport. Data presented here give an overview of the range of air pollution concentrations to expect under typical meteorological and seasonal conditions in the larger area of Bucharest.

The status and distribution of woodcock in Oklahoma  

USGS Publications Warehouse

The seasonal and spatial distributions of the American woodcock (Philohela minor) in Oklahoma were determined through field surveys and the collection of all known reports of woodcock sightings. Woodcock were reported in Oklahoma in all seasons and were most Jrequently sighted from 11 October to 10 January. The peak in fall migration occurred between 11 November and 10 December. Woodcock were found in 5 major areas across the eastern two-thirds of the state but 57 percent of the birds reported during the study were in the eastern one-third. A total of 148 displaying males were encountered on 25 sites in 15 of 29 counties included roadside singing ground surveys in 1975 and 1976. The peak number of displaying birds (58) was observed during the second IO-day period in February; displays occurred from January through late March. Personal observations plus data reported via volunteer survey cards, indicated that the typical site used for diurnal cover by woodcock in Oklahoma is a brushy bottomland with moist loamy soils, vegetated by oaks (Quercus spp.), elms (Ulmus spp,), bluestem grasses (Andropogon spp.), dogwoods (Cornus spp.) and green briars (Smilax spp.).

Quantitative analysis between spatial extents and spatial aggregation levels of urban built-up area using Landsat data and Aggregation Index: A case study of Nagoya City  

NASA Astrophysics Data System (ADS)

This paper shows a quantitative relationship between spatial extents and spatial aggregation levels of urban built-up area using Landsat data and Aggregation Index (AI) for the final goal of facilitating decision-making in urban planning. Two Landsat Thematic Mapper (TM) images acquired in 1985 and 1997 were used to map urban built-up areas, and AI were calculated to evaluate the spatial aggregation and dispersion levels of urban built-up areas quantitatively. Nagoya City, the fourth largest city in Japan and located in the central Japan, was selected as our study area. The spatial extent and AI of the urban built-up, forest, open field, and water classes were calculated in the entire study area and also ward levels (political districts in Nagoya City). The results showed that both values of urban built-up area increased between 1985 and 1997, but values of open field areas decreased during the same period. We found that most of open field areas loss was attributed to the creation of urban built-up areas. Furthermore, a strong positive correlation between the spatial extent and the AI values for urban built-up areas in all wards was found from our study result.

The human health impact of Nyiragongo and Nyamulagira eruptions on Goma city and its surrounding area  

NASA Astrophysics Data System (ADS)

Located in the east of the Democratic Republic of Congo (DRC), Nyiragongo and Nyamulagira are two of the most active volcanoes in Africa. Nyiragongo last erupted in January 2002 and Nyamulagira in November 2011. Even if only a small number of victims resulted directly from these eruptions (notably because they both happened in the day-time), the town of Goma (approx. 700 000 inhabitants) is directly threatened by the fluid lava flows, of which the speed can reach several tens of km/h. But this is not the only menace. Indeed, Nyiragongo hosts a permanent lava lake that produces a plume of gases rich in sulphur (SO2), carbon (CO2), and halogen compounds (HCl, HF). As for Nyamulagira, it makes a major contribution to these emissions during its frequent and regular periods of eruptive activity (approx. every two years). Although the region under study is densely populated (up to 250 inh/km2), and basic volcanic hazard mapping exists, an updated and long-term evaluation of the specific impact of Nyiragongo and Nyamulagira semi-permanent volcanic plumes on the population health has not been done to date. It is the objective of this study. Michigan Technological University (MTU, USA) provides satellite data retrievals of volcanogenic SO2 gas columns. These remote sensing data provide insights about the spatial distribution of Nyiragongo and Nyamulagira plumes, which are used to select the sampling areas for studying the human health impact of volcanic emissions. Based on the Congolese Health Information System (HIS) data provided by the CEMUBAC, our study is focused on the 1999-2010 time period. Scientific studies carried out on other active volcanoes suggest that certain pathologies could be linked to a high concentration of SO2 in the atmosphere. These include Acute Respiratory Infections (ARI), conjunctivitis, skin diseases, and ear-nose-throat infections. Using Poisson regression analysis, we determine a Relative Risk Index (IRR) that allows us to identify the years of higher health risk for the population living under the plume. Additionally, time series analysis helps us to disregard any seasonal effect of certain pathologies and to derive a 12-year risk trend. For 2004-2010, our results are compared to SO2 gas emission rates and plume location data measured by using Differential Optical Absorption Spectroscopic (DOAS) sensors located around Nyiragongo volcano. Finally, the areas identified as more hazardous are highlighted through a geographical approach (using GIS tools), to generate maps and other relevant information that can be of direct use for risk assessment authorities. Our preliminary analysis suggests that the impact of SO2 emissions doesn't seem to be severe, being its most important effect an increase of ARI in the area surrounding the volcanoes (up to 50km). Our on-going study will help us to better determine the magnitude and geographical extent of the impact of volcanic plumes on the health of the population, as well as locate the areas that are most affected. This will contribute to provide the appropriate sanitation recommendations (water treatment, early warning system, etc.) and lead to a more effective volcanic impact reduction on human health.

Energy balance of a suburban vegetated area in a tropical city--Delhi (India).  

PubMed

Energy balance measurements were carried out in a suburban vegetated area of southern part of Delhi. These measurements were made on several days during winter (January, February, November, December) and summer (April, May, June) of 1998 and 1999, respectively. During the winter 1998, net radiation (Q*) reached up to 108 W/m2 around noon and during the summer 1999, Q* was as high as 423.43 W/m2. The apportionments of Q* into sensible heat (H) and latent heat (LE) fluxes were 63% and 16% respectively during the summer 1998, whereas, during the winter Q* dissipated by 40% and 60%, respectively by H and LE. Similarly, during the summer 1999, partitioning of Q* into H and LE were 52 and 24%, respectively and during the winter, apportionments of H and LE found to be 37% and 39% respectively. On an average, about 34% of Q* was dissipated as soil heat flux (G) during both the summers (1998 and 1999) and the winter 1999, whereas, during the winter 1998, G was about 14% of Q*. Diurnal variations of H and LE showed erratic nature whereas that of G was relatively smoother during both the summers and winters. The calculated Bowen ratio was 0.67 to 0.91 during winters and 2.16 to 3.84 during summers, respectively. Probably, seasonal differences are due to local/synoptic conditions, nature of sub stratum and existence of vegetation, which influence the energy partitioning. However, as there was no surplus of energy, the area acts as a heat sink. PMID:19295092

Landslide prediction using combined deterministic and probabilistic methods in hilly area of Mt. Medvednica in Zagreb City, Croatia  

NASA Astrophysics Data System (ADS)

The hilly slopes of Mt. Medvednica are stretched in the northwestern part of Zagreb City, Croatia, and extend to approximately 180km2. In this area, landslides, e.g. Kostanjek landslide and ?rešnjevec landslide, have brought damage to many houses, roads, farmlands, grassland and etc. Therefore, it is necessary to predict the potential landslides and to enhance landslide inventory for hazard mitigation and security management of local society in this area. We combined deterministic method and probabilistic method to assess potential landslides including their locations, size and sliding surfaces. Firstly, this study area is divided into several slope units that have similar topographic and geological characteristics using the hydrology analysis tool in ArcGIS. Then, a GIS-based modified three-dimensional Hovland's method for slope stability analysis system is developed to identify the sliding surface and corresponding three-dimensional safety factor for each slope unit. Each sliding surface is assumed to be the lower part of each ellipsoid. The direction of inclination of the ellipsoid is considered to be the same as the main dip direction of the slope unit. The center point of the ellipsoid is randomly set to the center point of a grid cell in the slope unit. The minimum three-dimensional safety factor and corresponding critical sliding surface are also obtained for each slope unit. Thirdly, since a single value of safety factor is insufficient to evaluate the slope stability of a slope unit, the ratio of the number of calculation cases in which the three-dimensional safety factor values less than 1.0 to the total number of trial calculation is defined as the failure probability of the slope unit. If the failure probability is more than 80%, the slope unit is distinguished as 'unstable' from other slope units and the landslide hazard can be mapped for the whole study area.

Eddy Covariance Flux Measurements of Pollutant Gases in the Mexico City Urban Area: a Useful Technique to Evaluate Emissions inventories  

NASA Astrophysics Data System (ADS)

Direct measurements of emissions of pollutant gases that include all major and minor emissions sources in urban areas are a missing requirement to improve and evaluate emissions inventories. The quality of an urban emissions inventory relies on the accuracy of the information of anthropogenic activities, which in many cases is not available, in particular in urban areas of developing countries. As part of the MCMA-2003 field campaign, we demonstrated the feasibility of using eddy covariance (EC) techniques coupled with fast-response sensors to measure fluxes of volatile organic compounds (VOCs) and CO2 from a residential district of Mexico City. Those flux measurements demonstrated to be also a valuable tool to evaluate the emissions inventory used for air quality modeling. With the objective to confirm the representativeness of the 2003 flux measurements in terms of magnitude, composition and diurnal distribution, as well to evaluate the most recent emissions inventory, a second flux system was deployed in a different district of Mexico City during the 2006 MILAGRO field campaign. This system was located in a busy district surrounded by congested avenues close to the center of the city. In 2003 and 2006 fluxes of olefins and CO2 were measured by the EC technique using a Fast Isoprene Sensor calibrated with a propylene standard and an open path Infrared Gas Analyzer (IRGA), respectively. Fluxes of aromatic and oxygenated VOCs were analyzed by Proton Transfer Reaction-Mass Spectroscopy (PTR-MS) and the disjunct eddy covariance (DEC) technique. In 2006 the number of VOCs was extended using a disjunct eddy accumulation (DEA) system. This system collected whole air samples as function of the direction of the vertical wind component, and the samples were analyzed on site by gas chromatography / flame ionization detection (GC-FID). In both studies we found that the urban surface is a net source of CO2 and VOCs. The diurnal patterns were similar, but the 2006 fluxes showed higher magnitudes. This difference was due to the different characteristics of the monitored sites rather than an increment of the emissions over a 3-year period. The diurnal patterns of VOCs and CO2 fluxes were strongly related to vehicular traffic. Toluene and methanol fluxes also exhibited a strong influence from non-mobile sources; in particular the 2006 flux measurements were influenced on some days by the application of a resin to the sidewalks in the neighborhood near the flux tower. The fluxes of individual hydrocarbons measured by DEA showed good agreement with the fluxes measured by EC and DEC which demonstrates that the DEA method is valuable for flux measurements of additional individual species. Finally, the comparisons between the measured fluxes of VOCs and the emissions reported by the emissions inventory for the monitored sector of the city showed that these last were within the observed variability of the measured fluxes.

Records of wells and water quality for the Garber-Wellington Aquifer, northern Oklahoma and southern Logan Counties, Oklahoma  

USGS Publications Warehouse

The U.S. Geological Survey has collected data on Oklahoma's ground-water resources since 1934. Most of these data were collected as part of specific ground-water studies conducted in cooperation with various Federal, State, and local agencies. In 1972, at the request of the U.S. Bureau of Reclamation, the Geological Survey undertook a study of the Garber-Wellington aquifer in northern Oklahoma and southern Logan Counties. As a part of this project, records of about 120 wells were collected and 12 samples of ground water from the aquifer were analyzed in the laboratories of the Geological Survey; these records are included in this report. In addition, records of about 302 wells and analyses of 60 water samples were taken from a report by Wood and Burton (1966) and from the files of the Geological Survey. Also included in this report are selected references for those desiring more information on the area's ground-water resources. The stratigraphic nomenclature and age determinations used in this report are those accepted by the Oklahoma Geological Survey and do not necessarily agree with those of the U.S. Geological Survey. Acknowledgment is extended to the many hundred of individuals who have provided the data compiled in this report.

Contribution of the gasoline distribution cycle to volatile organic compound emissions in the metropolitan area of Mexico City.  

PubMed

Gasoline distribution in the metropolitan area of Mexico City (MAMC) represents an area of opportunity for the abatement of volatile organic compound (VOC) emissions. The gasoline distribution in this huge urban center encompasses several operations: (1) storage in bulk and distribution plants, (2) transportation to gasoline service stations, (3) unloading at service stations' underground tanks, and (4) gasoline dispensing. In this study, hydrocarbon (HC) emissions resulting from breathing losses in closed reservoirs, leakage, and spillage from the operations just listed were calculated using both field measurements and reported emission factors. The results show that the contribution of volatile HC emissions due to storage, distribution, and sales of gasoline is 6651 t/year, approximately 13 times higher than previously reported values. Tank truck transportation results in 53.9% of the gasoline emissions, and 31.5% of emissions are generated when loading the tank trucks. The high concentration of emissions in the gasoline transportation and loading operations by tank trucks has been ascribed to (1) highly frequent trips from distribution plant to gasoline stations, and vice versa, to cope with excessive gasoline sales per gasoline station; (2) low leakproofness of tank trucks; and (3) poor training of employees. In addition, the contribution to HC evaporative and exhaust emissions from the vehicles of the MAMC was also evaluated. PMID:12022693

Atmospheric deposition of selected chemicals and their effect on nonpoint-source pollution in the Twin Cities Metropolitan Area, Minnesota  

USGS Publications Warehouse

Atmospheric inputs and runoff concentrations of total Kjeldahl nitrogen, dissolved nitrite-plus-nitrate nitrogen, total phosphorus, total sulfate (only for atmospheric input), total chloride, and total lead were studied from April 1 to October 31 , 1980, in one rural and three urban watersheds in the Twin Cities metropolitan area, Minnesota. Seasonal patterns of wetfall and dryfall generally were similar for all constituents except chloride in both rural and urban watersheds. Similarity between constituents and between rural and urban watersheds suggested that regional air masses transported from the Gulf of Mexico by frontal storm movements influence seasonal patterns of atmospheric input in the metropolitan area. Local influences such as industrial, agricultural, and vehicular air pollutants were found to influence the magnitude or rate of atmospheric input rather than the seasonal pattern. Chloride was primarily influenced by northwest frontal storms laden with coastal chloride. Local influences such as dust from road de-icing salt are thought to have caused an increase in atmospheric chloride during June. The atmospheric contribution to nonpoint-source-runoff pollution of nitrogen, in the form of nitrite-plus-nitrate, and lead was extremely high, constituting as much as 84 percent of the runoff load. In contrast, phosphorus and chloride inputs were low, averaging 6 percent of the total runoff load. (USGS)

Construction-employment opportunities of four oil-replacing space-heating alternatives for core areas of thirteen major northeastern and midwestern cities  

SciTech Connect

Construction employment opportunities are compared for four oil-replacing technologies providing equivalent space-heating services to the core areas of 13 major northeastern and midwestern cities. The four technologies are: cogeneration district heating, coal gasification, coal liquefaction and electrification (coal-fired power plant). It is observed that the district-heating option places a higher percentage of its capital stock within the center city. It also requires lower occupational skills for its construction than the other three alternatives. In view of the lower average educational level of minorities and their concentration in urban areas, substantially more minority employment should occur if district heating is implemented. This alternative also will provide employment opportunities for unemployed nonminority construction laborers and contribute indirectly to the improvement of inner-city neighborhoods where many unemployed construction laborers live.

Reabilitation of degraded area by erosion, using soil bioengineering techniques in Bacanga river basin, Sao Luis City - Maranhao State, Brazil.  

NASA Astrophysics Data System (ADS)

The aim of this paper is to assess the stages of rehabilitation of a degraded site by erosion, in Salina/Sacavém district, São Luís City, considering geomorphologic characteristics and soil bioengineering techniques. This technique has been applied in different situations to rehabilitate degraded areas, with positive results from the use of biodegradable materials (e.g. vegetal fibres, wooden stakes and re-vegetation). These techniques stabilize the soil at low cost and improve the environment. Bioengineering involves the planned and strategic application of selected materials, involving biodegradable materials, often in combination with 'hard engineering' structures constructed from stone, concrete and steel. The settlement of São Luís was established in 1612 and has evolved in distinct phases. Rapid urban growth was associated with industrialization in the second half of the 18th Century. Rapid population and urban growth has intensified problems, compounded by poor planning and improper soil use. São Luís, like many other Brazilian cities, has experienced rapid population growth in recent decades, which has created a series of socio-economic and environmental problems, including accelerated soil erosion. Sacavém is one of these communities where natural and human factors contribute to the severe gully erosion. The local lithology is mainly Tertiary sandstones and, to a lesser extent, shales, argillites and siltstones, all of which belong to the Barreiras Formation. Weathering on these rocks produces erodible soils, including lithosols, latosols, concretionary red/yellow clay soils and concretionary plinthosols. Thus, erodible soils and regolith are subject to high erosion rates, especially on steeper slopes subject to additional human interventions. Furthermore, although regional slopes are quite gentle, there is localized high relative relief. Sacavém vegetation, in the gullied area, consists of brushwood. Secondary mixed forest and brushwood are the dominant vegetal cover adjacent to the urban gullies. The local climate is humid tropical, with average annual temperatures of 26°C, reaching higher values in October to December and lower from April to June. Rainfall distribution throughout the year is irregular, marked by two very distinct seasons (rainy and dry). The highly seasonal erosive rains incise a complex series of soil erosion landforms, mainly gullies in this area. The following procedures have been carried out: fieldwork with monitoring of gully head erosion; Environmental Education Program; handcraft workshop regarding the prodution of geotextiles from Buriti fiber. The rehabilitation of this degraded site, follows these stages: 1. Acquisition of equipment and materials; 2. Contracting workers; 3. Reshaping selected gully walls; 4. Adding organic palm materials to the topsoil and ~30 kg of grass seeds; 5. Application of geotextile anchored on the ground by using wooden stakes; 6. Maintenance work with photographic records; 7. Photo comparison to measure the vegetal cover percentage, with the aid of geoprocessing software. Some of the gully walls presented steep slopes, around 90 degrees, and therefore, it was necessary to reshape them for the application of soil bioengineering techniques. It was selected a sample area of 2.000 m2 to be rehabilitated. The knowledge of soil and geomorphological characteristics was essential to understand surface runoff, considering the direction of water flows. Due to the difficulties in diverting the flows, which would require more extensive engineering works, the channel was maintained, and the base of the slopes was strengthened to support the flows. In the upper part of this area, which had ~8° slope angle, contour lines were surveyed and barriers of wooden stakes were used to retard runoff velocity from adjacent vegetated slopes. Some slopes in this part had a 45° slope angle, due to the local topography. However, this angle is considered too steep for the application of palm-mats. In some parts of gully, work was completed to reshape the gullies and constru

Atokan (Pennsylvanian) Berlin field: genesis of recycled detrital Dolomite Reservoir, deep Anadarko basin, Oklahoma  

SciTech Connect

The Berlin gas field in Beckham County, Oklahoma, was discovered in 1977 and is the largest Atoka (Pennsylvanian) hydrocarbon accumulation in the Anadarko basin. It is an overpressured reservoir 15,000 ft (4,572 m) deep and occupies a surface area of 41 miS (106 kmS). The reservoir rock consists primarily of recycled, detrital Arbuckle Dolomite (Cambrian-Ordovician), and contains ultimate recoverable reserves of 242 to 362 bcf (6,850 to 10,250 X 10W mT). The deep Elk City structure consists of an upthrust block bounded by the late Atokan unconformity which is genetically associated with the Berlin fan delta. The present relief on the upthrust block and overlying anticlinal folds was formed during post-Atokan growth of the structure. The Berlin field provides a model of a large, localized detrital deposit derived from uplift and erosion of a prominent structure, and it is an example of the potential for large detrital stratigraphic traps around the perimeters of prominent structures containing crestal unconformities.

Emission factors for domestic use of L.P. gas in the metropolitan area of Mexico City  

SciTech Connect

One of the main problems found in air pollution in the Metropolitan Area of Mexico City (MAMC) is the presence of high concentrations of ozone at ground level in the atmosphere. The official Mexican standard for ozone concentration in the air (0.11 ppm, one hour, once every 3 years) has been exceeded more than 300 days per year. Ozone is formed due to the emissions of nitrogen oxides and hydrocarbons originated from either combustion processes or vapors emanating from fuel handling operations. The results of an evaluation of several domestic devices like stoves and water heaters with L.P. gas as fuel are presented. A method for the evaluation of hydrocarbon emission was developed. A prototype of domestic installation was constructed. The prototype includes L.P. gas tank, domestic stove, water heater, piping and instrumentation. Several combinations of stoves and water heaters were evaluated. The sampling and analysis of hydrocarbons were performed using laboratory equipment originally designed for the evaluation of combustion and evaporative emissions in automobiles: a SHED camera (sealed room equipped with an hydrocarbon analyzer) was used to measure leaks in the prototype of domestic installation and a Constant Volume Sampler (CVS) for the measurement of incomplete combustion emissions. Emission factors were developed for each domestic installation.

Characterization of water pollution in drainage networks using continuous monitoring data in the Citadel area of Hue City, Vietnam.  

PubMed

In the Citadel area of Hue City, drainage systems that include canals and ponds are considerable sources of fecal contaminants to inundated water during the rainy season because canals and ponds receive untreated wastewater. It is important to investigate the characteristics of hydraulics and water pollution in canals and ponds. At the canals and ponds, water sampling was conducted during dry and wet weather periods in order to evaluate fecal contamination and to investigate changes in water pollution caused by runoff inflow. Inundated water was also collected from streets during heavy rainfall. At the canals and ponds, concentrations of Escherichia coli and total coliform exceeded the Vietnamese regulation values for surface water in 23 and 24 out of 27 samples (85 and 89%), respectively. The water samples were categorized based on the characteristics of water pollution using cluster analysis. In the rainy season, continuous monitoring was conducted at the canals and ponds using water depth and electrical conductivity (EC) sensors to investigate the dynamic relationship between water level and water pollution. It is suggested that in the canals, high EC meant water stagnation and low EC signified river water inflow. Therefore, EC might be a good indicator of water flow change in canals. PMID:25116489

It is a transverse study where a questionnaire of alimentary frequency was applied (QAF) in 150 adults resident of the rural area of the city of Ibatiba (ES, Brazil). QAF classified the alimentary consumption as: habitual (>4 times in the week), not habitual (<4 times in the week) and rarely (1 time a month), with objective of correlating the alimentary consumption with the chronic-degenerative diseases. The results evidenced a habitual consumption of rice, breads, stalk, bean, cow milk, animal fat, margarine, sugar and coffee, and a non habitual consumption of cake, potato, cookies, manioc, sweet potato, chayote, carrot, beet, pumpkin, juice of fruits, banana, orange, guava, mango and tangerine. It can be concluded that the feeding habit presented by the studied population it can come to increase in a medium or long period the prevalence and occurrences of chronic-degenerative diseases as hypertension, diabetes, obesity and coronary diseases. The alimentary consumption of this population needs concern, because when compared with the national patterns, it is observed some inadequacies, and it is known that this picture comes to every day causing damages the public health.

A Total Lightning Perspective of the 20 May 2013 Moore, Oklahoma Supercell  

NASA Technical Reports Server (NTRS)

In the early afternoon of 20 May 2013, a storm initiated to the west-southwest of Newcastle, Oklahoma. This storm would rapidly intensify into the parent supercell of the tornado that struck the city of Moore, Oklahoma. This article describes what contributions total lightning observations from the Oklahoma Lightning Mapping Array could provide to operational forecasters had these observations been available in real-time. This effort includes a focus on the GOES-R pseudo-geostationary lightning mapper demonstration product as well as the NASA SPoRT / Meteorological Development Laboratory's total lightning tracking tool. These observations and tools identified several contributions. Two distinct lightning jumps at 1908 and 1928 UTC provided a lead time of 19 minutes ahead of severe hail and 26 minutes ahead of the Moore, Oklahoma tornado's touchdown. These observations provide strong situational awareness to forecasters, as the lightning jumps are related to the rapid strengthening of the storm's updraft and mesocyclone and serve as a precursor to the stretching of the storm vortex ahead severe weather.

Observed and simulated sensitivities of summertime urban surface air temperatures to anthropogenic heat in downtown areas of two Japanese Major Cities, Tokyo and Osaka  

NASA Astrophysics Data System (ADS)

In this study, the sensitivities of surface air temperatures to anthropogenic heat (AH) were investigated in downtowns of the two Japanese major cities, Tokyo and Osaka. First, meteorological measurements were made with the simultaneous monitoring of electricity demand in a contrastive couple of a downtown commercial area (C-area) and a residential area (R-area) within each city in summer 2007. From the measurements, the areal-mean surface air temperatures were obtained as and for each of the C-area and R-area, respectively. Using the actual electricity demand and the estimated motor fuels consumption, their areal total was evaluated as the energy-consumption-basis AH. The estimated C-areas' AH indicated greater values up to 220 W/m2 on weekdays and remarkable decrease about by half on weekends, whereas that in the R-areas showed less values of 10-20 W/m2 stably. Then, on calm and fine days were found to be systematically decreased from weekdays to weekends in both cities roughly indicating a proportional relationship with the reductions in the C-areas' AH on weekends. The result suggested a common afternoon sensitivity for both C-areas of around 1.0°C/100 W/m2, which indicated an intensity of the AH impact on surface air temperature there. Next, to simulate the observed AH impact, the authors' CM-BEM (a multilayer urban canopy model coupled with a building energy model) was newly implemented in the mesoscale Weather Research and Forecasting (WMF) model. This new system, WRF-CM-BEM, was applied to Tokyo and almost reasonably validated from the aspects of the reproducibility of urban surface air temperature and electricity demand in the observation areas. The simulations also suggested that WRF-CM-BEM underestimated the observed air temperature sensitivity to AH in the Tokyo C-area roughly by half but still in the same order of magnitude.

Preliminary United States-Mexico border watershed analysis, twin cities area of Nogales, Arizona and Nogales, Sonora  

USGS Publications Warehouse

The United States - Mexico border area faces the challenge of integrating aspects of its binational physical boundaries to form a unified or, at least, compatible natural resource management plan. Specified geospatial components such as stream drainages, mineral occurrences, vegetation, wildlife, and land-use can be analyzed in terms of their overlapping impacts upon one another. Watersheds have been utilized as a basic unit in resource analysis because they contain components that are interrelated and can be viewed as a single interactive ecological system. In developing and analyzing critical regional natural resource databases, the Environmental Protection Agency (EPA) and other federal and non-governmental agencies have adopted a ?watershed by watershed? approach to dealing with such complicated issues as ecosystem health, natural resource use, urban growth, and pollutant transport within hydrologic systems. These watersheds can facilitate the delineation of both large scale and locally important hydrologic systems and urban management parameters necessary for sustainable, diversified land-use. The twin border cities area of Nogales, Sonora and Nogales, Arizona, provide the ideal setting to demonstrate the utility and application of a complete, cross-border, geographic information systems (GIS) based, watershed analysis in the characterization of a wide range of natural resource as well as urban features and their interactions. In addition to the delineation of a unified, cross-border watershed, the database contains sewer/water line locations and status, well locations, geology, hydrology, topography, soils, geomorphology, and vegetation data, as well as remotely sensed imagery. This report is preliminary and part of an ongoing project to develop a GIS database that will be widely accessible to the general public, researchers, and the local land management community with a broad range of application and utility.

Aquifer geochemistry at potential aquifer storage and recovery sites in coastal plain aquifers in the New York city area, USA  

USGS Publications Warehouse

The effects of injecting oxic water from the New York city (NYC) drinking-water supply and distribution system into a nearby anoxic coastal plain aquifer for later recovery during periods of water shortage (aquifer storage and recovery, or ASR) were simulated by a 3-dimensional, reactive-solute transport model. The Cretaceous aquifer system in the NYC area of New York and New Jersey, USA contains pyrite, goethite, locally occurring siderite, lignite, and locally varying amounts of dissolved Fe and salinity. Sediment from cores drilled on Staten Island and western Long Island had high extractable concentrations of Fe, Mn, and acid volatile sulfides (AVS) plus chromium-reducible sulfides (CRS) and low concentrations of As, Pb, Cd, Cr, Cu and U. Similarly, water samples from the Lloyd aquifer (Cretaceous) in western Long Island generally contained high concentrations of Fe and Mn and low concentrations of other trace elements such as As, Pb, Cd, Cr, Cu and U, all of which were below US Environmental Protection Agency (USEPA) and NY maximum contaminant levels (MCLs). In such aquifer settings, ASR operations can be complicated by the oxidative dissolution of pyrite, low pH, and high concentrations of dissolved Fe in extracted water.The simulated injection of buffered, oxic city water into a hypothetical ASR well increased the hydraulic head at the well, displaced the ambient groundwater, and formed a spheroid of injected water with lower concentrations of Fe, Mn and major ions in water surrounding the ASR well, than in ambient water. Both the dissolved O2 concentrations and the pH of water near the well generally increased in magnitude during the simulated 5-a injection phase. The resultant oxidation of Fe2+ and attendant precipitation of goethite during injection provided a substrate for sorption of dissolved Fe during the 8-a extraction phase. The baseline scenario with a low (0.001M) concentration of pyrite in aquifer sediments, indicated that nearly 190% more water with acceptably low concentrations of dissolved Fe could be extracted than was injected. Scenarios with larger amounts of pyrite in aquifer sediments generally resulted in less goethite precipitation, increased acidity, and increased concentrations of dissolved Fe in extracted water. In these pyritic scenarios, the lower amounts of goethite precipitated and the lower pH during the extraction phase resulted in decreased sorption of Fe2+ and a decreased amount of extractable water with acceptably low concentrations of dissolved Fe (5.4??10-6M). A linear decrease in recovery efficiency with respect to dissolved Fe concentrations is caused by pyrite dissolution and the associated depletion of dissolved O2 (DO) and increase in acidity. Simulations with more than 0.0037M of pyrite, which is the maximum amount dissolved in the baseline scenario, had just over a 50% recovery efficiency. The precipitation of ferric hydroxide minerals (goethite) at the well screen, and a possible associated decrease in specific capacity of the ASR well, was not apparent during the extraction phase of ASR simulations, but the model does not incorporate the microbial effects and biofouling associated with ferric hydroxide precipitation.The host groundwater chemistry in calcite-poor Cretaceous aquifers of the NYC area consists of low alkalinity and moderate to low pH. The dissolution of goethite in scenarios with unbuffered injectate indicates that corrosion of the well could occur if the injectate is not buffered. Simulations with buffered injectate resulted in greater precipitation of goethite, and lower concentrations of dissolved Fe, in the extracted water. Dissolved Fe concentrations in extracted water were highest in simulations of aquifers (1) in which pyrite and siderite in the aquifer were in equilibrium, and (2) in coastal areas affected by saltwater intrusion, where high dissolved-cation concentrations provide a greater exchange of Fe2+ (FeX2). Results indicate that ASR in pyrite-beari

Characterization of the NOx-Ox relationship in a mountain gap rural area of interchange of air masses southeast of the Metropolitan Area of Mexico City  

NASA Astrophysics Data System (ADS)

Varying levels of oxidants (Ox = O3 + NO2) with respect to NOx were registered at three sites in a mountain southeast of the Mexico City Metropolitan Area (MCMA) in February and March 2011. The Ox-NOx ratio was used to gain a better understanding of the photochemical and transport processes happening over this mountain pass. Relatively high concentrations of O3 (moving average concentrations of 8 hours) exceeded maximum levels of the World Health Organization, and the European Union. The cumulative exceedances above background level of O3 in the one month-long campaign also exceeded the three months accumulative UN-ECE AOT40 critical level for crop protection. It was observed that the level of Ox in the mountain gap sites consisted of two contributions: One, independent of NOx emissions, extremely dominant and considered equivalent to the regional background O3 concentration; the second and much smaller was dependent of NOx local concentrations. Evidence was found that the oxidation of NO provided the major contribution of NO2 to Ox, rather than direct NO2 emissions. The contribution of regional Ox dominated from midmorning to noon when the boundary layer height began to increase due to sunlight heating of the surface leading to the mixing of higher concentrations of O3 above the nighttime thermal inversion. After noon, when the ozone vertical distribution was uniform, the Ox and O3 concentrations reached their maximum; they were very similar with very low levels of NO2. The analysis of wind data collected at the monitoring sites showed that from mid-morning to early afternoon, a northerly weak flow was common. Afterwards stronger southerly winds became dominant bringing in O3 rich air parcels into the atmospheric basin where MCMA is located. The high regional ozone concentrations add evidence for the need of coordinated air quality management policies for the complete central part of Mexico.

Iron-rich Oklahoma clays as a natural source of chromium in monitoring wells.  

PubMed

Water samples, drawn from groundwater monitoring wells located southeast of Oklahoma City, OK, were found to contain elevated concentrations of total chromium with an apparent source localized to the area surrounding each well. Since these monitoring wells are located in areas with no historic chromium usage, industrial sources of chromium were ruled out. Water testing was performed on twelve monitoring wells in the area that historically had elevated total chromium concentrations ranging from 10-4900 micrograms per litre. Filtered water samples were found to be free of chromium contamination, indicating that the source of the chromium is the suspended solids. Analysis of these solids by acid digestion and a sequential extraction technique revealed that the chromium was primarily associated with iron-containing solids. X-ray diffraction identified goethite, an iron oxide hydroxide, as the dominant iron-containing phase in the suspended solids. The mineralogy in this region is dominated by interbedded red-bed sandstone and mudstone whose mineral content includes mixed-layer illite-smectite, hematite, goethite, gypsum and dolomite. Elemental analysis of soil samples collected as a function of depth in the locale of the monitoring wells indicated that the iron rich clays contain a natural source of chromium. The elevated levels of total chromium are most likely due to the dissolution of silica and alumina from the chromium containing iron clays in the basic well water, resulting in the release of fine suspended solids that naturally have high chromium concentrations. These results should be applicable to other areas containing iron-rich clays. PMID:22027925

Variation in use of Buprenorphine and Methadone Treatment by Racial, Ethnic and Income Characteristics of Residential Social Areas in New York City  

PubMed Central

National data indicate that patients treated with buprenorphine for opiate use disorders are more likely to be White, highly educated, and to have greater incomes than those receiving methadone, but patterns of buprenorphine dissemination across demographic areas have not been documented in major metropolitan areas where poverty, minority populations and injection heroin use are concentrated. Rates of buprenorphine and methadone treatment are compared among areas of New York City defined by their income and ethnic/racial composition. Residential social areas (hereinafter called social areas) were defined as aggregations of ZIP codes with similar race/ethnicity and income characteristics, and were formed based on clustering techniques. Treatment rates were obtained for each New York City ZIP code: buprenorphine treatment rates were based on the annual number of buprenorphine prescriptions written, and the methadone treatment rate on the number of methadone clinic visits for persons in each ZIP code. Treatment rates were correlated univariately with ethnicity and income characteristics of ZIP codes. Social area treatment rates were compared using individual ANOVA models for each rate. Buprenorphine and methadone treatment rates were significantly correlated with the ethnicity and income characteristics of ZIP codes, and treatment rates differed significantly across the social areas. Buprenorphine treatment rates were highest in the social area with the highest income and lowest percentage of Black and Hispanic residents. Conversely, the methadone treatment rate was highest in the social area with the highest percentage of low income and Hispanic residents. The uneven dissemination of 0pioid maintenance treatment in New York City may be reflective of the limited public health impact of buprenorphine in ethnic minority and low income areas. Specific policy and educational interventions to providers are needed to promote the use of buprenorphine for opiate use disorders in diverse populations. PMID:23702611

Atokan (Pennsylvanian) Berlin field: genesis of recycled detrital dolomite reservoir, deep Anadarko Basin, Oklahoma  

SciTech Connect

The Berlin gas field in Beckham County, Oklahoma, was discovered in 1977 and is the largest Atoka (Pennsylvanian) hydrocarbon accumulation in the Anadarko basin. It is an overpressured reservoir 15,000 ft (4572 m) deep and occupies a surface area of 41 mi/sup 2/ (106 km/sup 2/). The reservoir rock consists primarily of recycled, detrital Arbuckle Dolomite (Cambrian-Ordovician), and contains ultimate recoverable reserves of 242 to 362 bcf (6850 to 10,250 x 10/sup 6/ m/sup 3/). The Arbuckle Dolomite and limited exposures of Precambrian granite rocks were eroded from the Amarillo-Wichita mountains during the Atokan and were deposited as a terrigenous, sandy dolomite clastic wedge adjacent to the uplift. During the late Atokan, the Elk City structure was uplifted and subaerially exposed in the vicinity of the northern limit of the dolomite clastic wedge. The detrital dolomite on the structure was concurrently eroded and recycled northward as a shallow marine fan delta. Subsequent recrystallization destroyed the detrital depositional texture and created the present intercrystalline porosity. The deep Elk City structure consists of an upthrust block bounded by the late Atokan unconformity which is genetically associated with the Berlin fan delta. The present relief on the upthrust block and overlying anticlinal folds was formed during post-Atokan growth of the structure. The Berlin field provides a model of a large, localized detrital deposit derived from uplift and erosion of a prominent structure, and it is an example of the potential for large detrital stratigraphic traps around the perimeters of prominent structures containing crestal unconformities. 14 figures, 1 table.

Subsurface temperature anomalies as a key to petroleum-producing areas in the Cherokee and Forest City Basins, eastern Kansas?  

SciTech Connect

The relation of subsurface temperature to `plain-type fold` structure in the Midcontinent (USA) as an exploration tool has been speculated on for a long time. Structural highs, termed `plains-type folds,` are partly the result of differential compaction of sediments over rigid crystalline fault blocks in the Precambrian basement. In the Midcontinent, bottom-hole temperature (BHT) data, temperatures measured in drillstem tests (DSTs), and structural data are abundant. In the Cherokee and Forest City Basins, we analyzed BHT data by depth and stratigraphic unit (Cambro-Ordovician Arbuckle carbonates; Mississippian carbonates; and Perm-Pennsylvanian clastics). By relating the BHTs to DSTs, it was noted that the thermal disturbance inherent in BHT by drilling is minor and comparable within a formation. Also, the signal-noise ratio of BHTs could be improved utilizing the large data set. Although the resulting BHT formation gradients show unexpected values from the thermal conductivity in the carbonates and from the evaluated temperature disturbance by the drilling process, analysis of the BHT spatial pattern shows a coincidence of structural highs and temperature anomalies both in the clastics and in the carbonates. These BHT anomalies are outlined by values higher than the regional temperature trend. We attribute the anomalies partly to the insulation effect of petroleum (which may include the self-generation of heat) and partly to the movement of fluids vertically through the fracture and fault system created in the sedimentary veneer. Numerous examples from the oil- and gas-producing areas in eastern Kansas show that the nature of origin of fluids contained in a porous medium can alter local geothermal conditions.

Barriers to use of modern contraceptives among women in an inner city area of Osogbo metropolis, Osun state, Nigeria  

PubMed Central

Objectives To determine the knowledge and attitudes on modern contraceptive use of women living in an inner city area of Osogbo. Materials and methods Three hundred and fifty nine women of childbearing age were studied utilizing a community-based, descriptive, cross-sectional study design. A multistage random sampling technique was used in recruiting respondents to the study. A four-part questionnaire was applied dually, by interviewers and by respondents’ self administration, and the data was analyzed using the SPSS software version 17.0. Results The mean age of respondents was 28.6 ± 6.65 years. The majority (90.3%) of respondents were aware of modern methods of family planning (FP), 76.0% claimed awareness of where to obtain FP services, and 74.9% knew of at least five methods. However, only 30.6% had ever used contraceptives, while only 13.1% were current users. The most frequently used method was the male condom. The commonly perceived barriers accounting for low use of FP methods were fear of perceived side effects (44.0%), ignorance (32.6%), misinformation (25.1%), superstition (22.0%), and culture (20.3%). Some reasons were proffered for respondents’ nonuse of modern contraception. Predictors of use of modern contraceptives include the awareness of a place of FP service provision, respondents’ approval of the use of contraceptives, higher education status, and being married. Conclusion Most of the barriers reported appeared preventable and removable and may be responsible for the reported low point prevalence of use of contraceptives. It is recommended that community-based behavioral-change communication programs be instituted, aimed at improving the perceptions of women with respect to bridging knowledge gaps about contraceptive methods and to changing deep-seated negative beliefs related to contraceptive use in Nigeria.

Emissions of black carbon and co-pollutants emitted from diesel vehicles in the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

Black carbon emitted from freight, public transport, and heavy duty trucks sources is linked with adverse effects on human health. In addition, the control of emissions of black carbon, an important short-lived climate forcing agent (SLCF), has recently been considered as one of the key strategies for mitigating regional near-term climate change. Despite the availability of new emissions control technologies for reducing emissions from diesel-powered mobile sources, their introduction is still not widespread in many urban areas and there is a need to characterize real-world emission rates of black carbon from this key source. The emissions of black carbon, organic carbon, and other gaseous and particle pollutants from diesel-powered mobile sources in Mexico were characterized by deploying a mobile laboratory equipped with real-time instrumentation in Mexico City as part of the SLCFs-Mexico 2013 project. From February 25-28 of 2013 the emissions from selected diesel-powered vehicles were measured in both controlled experiments and real-world on-road driving conditions. Sampled vehicles had several emissions levels technologies, including: EPA98, EPA03, EPA04, EURO3-5, and Hybrid. All vehicles were sampled using diesel fuel and several vehicles were measured using both diesel and biodiesel fuels. Additional measurements included the use of a remote sensing unit for the co-sampling of all tested vehicles, and the installation and operation of a Portable Emissions Measurements System (PEMS) for the measurement of emissions from a test vehicle. We will present inter-comparisons of the emission factors obtained among the various vehicle technologies that were sampled during the experiment as well as the inter-comparison of results from the various sampling platforms.

An economic assessment of the application of superconductor technology to magnetic-levitation trains in Oklahoma  

SciTech Connect

Specific objectives were to: (1) develop and refine a methodology that can be used to evaluate the feasibility of MAG-LEV trains; (2) apply this methodology to the state of Oklahoma. The methodology is based on an aggregate econometric demand model and mathematical programming. A city-pair network is constructed to evaluate alternative MAG-LEV routes between Oklahoma City and nine other cites in and out of the state of Oklahoma. Results obtained from the aggregate econometric demand model indicates that MAG-LEV trains would attract significant ridership along different types of origin-destination routes. All nine corridors exhibit induced demand for MAG-LEV trains as well as attracting riderships from other modes. Based on the results of both single and multiobjective LP models, fixed-capital-cost requirements and annual operating cost for each of the above corridors are estimated, and by using different scenarios for discount rates, both costs and revenue were converted to annual figures using an annual-cost method.

Nonmarital births in Oklahoma 1975-1995.  

PubMed

This report uses data from the Oklahoma State Department of Health to describe past trends and current patterns of nonmarital births in Oklahoma. Between 1975 and 1995, the percentage of unmarried women delivering a live birth in Oklahoma increased from 12% to 31%. Adult nonmarital births increased faster than teen nonmarital births, but teens had a higher percentage of nonmarital births. White rates increased faster than African-American and Native American rates, but African-Americans had a higher percentage of nonmarital births. Unmarried women who give birth were more likely to be poor and lack education; additionally, they were less likely to receive early prenatal care, more likely to have had low weight births, and more likely to have had an unintended pregnancy. Birth outcomes are poorer among unmarried women, but this may be due to poverty and education rather than marital status alone. PMID:9583321

Characterization of Fine Particulate Matter (PM) and Secondary PM Precursor Gases in the Mexico City Metropolitan Area  

SciTech Connect

This project was one of three collaborating grants funded by DOE/ASP to characterize the fine particulate matter (PM) and secondary PM precursors in the Mexico City Metropolitan Area (MCMA) during the MILAGRO Campaign. The overall effort of MCMA-2006, one of the four components, focused on i) examination of the primary emissions of fine particles and precursor gases leading to photochemical production of atmospheric oxidants and secondary aerosol particles; ii) measurement and analysis of secondary oxidants and secondary fine PM production, with particular emphasis on secondary organic aerosol (SOA), and iii) evaluation of the photochemical and meteorological processes characteristic of the Mexico City Basin. The collaborative teams pursued the goals through three main tasks: i) analyses of fine PM and secondary PM precursor gaseous species data taken during the MCMA-2002/2003 campaigns and preparation of publications; ii) planning of the MILAGRO Campaign and deployment of the instrument around the MCMA; and iii) analysis of MCMA-2006 data and publication preparation. The measurement phase of the MILAGRO Campaign was successfully completed in March 2006 with excellent participation from the international scientific community and outstanding cooperation from the Mexican government agencies and institutions. The project reported here was led by the Massachusetts Institute of Technology/Molina Center for Energy and the Environment (MIT/MCE2) team and coordinated with DOE/ASP-funded collaborators at Aerodyne Research Inc., University of Colorado at Boulder and Montana State University. Currently 24 papers documenting the findings from this project have been published. The results from the project have improved significantly our understanding of the meteorological and photochemical processes contributing to the formation of ozone, secondary aerosols and other pollutants. Key findings from the MCMA-2003 include a vastly improved speciated emissions inventory from on-road vehicles: the MCMA motor vehicles produce abundant amounts of primary PM, elemental carbon, particle-bound polycyclic aromatic hydrocarbons, carbon monoxide and a wide range of air toxics; the feasibility of using eddy covariance techniques to measure fluxes of volatile organic compounds in an urban core and a valuable tool for validating local emissions inventory; a much better understanding of the sources and atmospheric loadings of volatile organic compounds; the first spectroscopic detection of glyoxal in the atmosphere; a unique analysis of the high fraction of ambient formaldehyde from primary emission sources; characterization of ozone formation and its sensitivity to VOCs and NOx; a much more extensive knowledge of the composition, size distribution and atmospheric mass loadings of both primary and secondary fine PM, including the fact that the rate of MCMA SOA production greatly exceeded that predicted by current atmospheric models; evaluations of significant errors that can arise from standard air quality monitors for O3 and NO2; and the implementation of an innovative Markov Chain Monte Carlo method for inorganic aerosol modeling as a powerful tool to analyze aerosol data and predict gas phase concentrations where these are unavailable. During the MILAGRO Campaign the collaborative team utilized a combination of central fixed sites and a mobile laboratory deployed throughout the MCMA to representative urban and boundary sites to measure trace gases and fine particles. Analysis of the extensive 2006 data sets has confirmed the key findings from MCMA-2002/2003; additionally MCMA-2006 provided more detailed gas and aerosol chemistry and wider regional scale coverage. Key results include an updated 2006 emissions inventory; extension of the flux system to measure fluxes of fine particles; better understanding of the sources and apportionment of aerosols, including contribution from biomass burning and industrial sources; a comprehensive evaluation of metal containing particles in a complex urban environment; identification of a close correlation between

Identification and evaluation of fluvial-dominated deltaic (Class 1 oil) reservoirs in Oklahoma. Yearly technical progress report, January 1--December 31, 1994  

SciTech Connect

The Oklahoma Geological Survey and the University of Oklahoma are engaged in a five-year program to identify and address Oklahoma`s oil recovery opportunities in fluvial-dominated deltaic (FDD) reservoirs. This program includes the systematic and comprehensive collection, evaluation, and distribution of information on all of Oklahoma`s FDD oil reservoirs and the recovery technologies that can be applied to those reservoirs with commercial success. To date, the lead geologists have defined the initial geographic extents of Oklahoma`s FDD plays, and compiled known information about those plays. Nine plays have been defined, all of them Pennsylvanian in age and most from the Cherokee Group. A bibliographic database has been developed to record the literature sources and their related plays. Trend maps are being developed to identify the FDD portions of the relevant reservoirs, through accessing current production databases and through compiling the literature results. A reservoir database system also has been developed, to record specific reservoir data elements that are identified through the literature, and through public and private data sources. The project team is working with the Oklahoma Nomenclature Committee of the Mid-Continent Oil and Gas Association to update oil field boundary definitions in the project area. Also, team members are working with several private companies to develop demonstration reservoirs for the reservoir characterization and simulation activities. All of the information gathered through these efforts will be transferred to the Oklahoma petroleum industry through a series of publications and workshops. Additionally, plans are being developed, and hardware and software resources are being acquired, in preparation for the opening of a publicly-accessible computer users laboratory, one component of the technology transfer program.

Thermal conditions in the Anadarko basin, Oklahoma  

SciTech Connect

Heat flow, bottom-hole temperature (BHT), and thermal conductivity data are used to evaluate the present thermal conditions in the Anadarko basin. Heat flow values decrease from 54-62 mWm{sup {minus}2} in the northern part of the basin to 39-53 mWm{sup {minus}2} in the southern portion of the basin. The variation in the regional conductive heat flow is controlled by basin geometry and by the distribution of radiogenic elements in the basement. The heat flow, thermal conductivity, and lithologic information were combined to construct a 3-D model of the temperature structure of the Anadarko basin. The highest temperatures sedimentary rocks older than Pennsylvanian are offset 35 km north-northwest of the deepest part of the basin. This offset is related to the regional increase in heat flow to the north and to the presence of high thermal conductivity granite wash adjacent to the Wichita Mountains. A plot of the temperature difference between the equilibrium temperatures estimated from the model and the measured BHTs as a function of depth is remarkably similar to the published correction curve for BHTs for wells in Oklahoma. Vitrinite reflectance and apatite fission-track (FT) data are used to estimate the paleogeothermal conditions in the basin. Published vitrinite reflectance values are consistent with a past geographic temperature distribution comparable to the observed distribution with the maximum values offset from the basin axis. FT analysis of sandstones from wells in the southeastern portion of the basin indicates that subsurface temperatures were at least 30C higher than at present, suggest the possibility of substantial erosion in this area.

Human population growth and temperature increase along with the increase in urbanisation, motor vehicle numbers and green area amount in the sample of Erzurum city, Turkey.

In the study, main purpose was to determine the effect of population growth along with the increase in urbanisation, motor vehicle use and green area amount on the temperature values using a 55-year data set in Erzurum, which is hardly industrialised, and one of the coldest cities with highest elevation in Turkey. Although the semi-decadal increases, means of which are 0.1 degrees C for mean, minimum and maximum temperatures, are not clear enough to make a strong comment even in the lights of figures or tables, it was found as the result of the statistical analysis that population growth and increases in the number of vehicles, the number of buildings and the green area amount in the city have no significant effect on mean temperatures. However, the relationships between population growth and maximum temperature; and the number of vehicles and minimum temperature were found to be statistically significant. PMID:18210203

Microbial and geochemical quality of shallow well water in high-density areas in Mzuzu City in Malawi  

NASA Astrophysics Data System (ADS)

In Malawi, shallow wells constitute the most important water sources for domestic purposes. However, increasing human population coupled with poor sanitation and infrastructure is undermining the quality of shallow well water. An assessment of microbial and geochemical quality of shallow well water in high-density areas of Zolozolo, Ching’ambo and Chiputula in Mzuzu City, Northern Malawi, has been carried out. The study aimed at characterising domestic water sources, identifying possible sources of water contamination and determining levels of microbial and chemical contamination. Arc-view GIS was used to map the water sources. A questionnaire survey was carried out to elicit information on characteristics of drinking water sources. Water samples were collected from quasi-randomly selected shallow wells and analysed for microbial and chemical parameters using standard methods. HCA, performed using R-programme, was used to group sampled sites according to their bio-physicochemical characteristics. Compliance of the water with MBS/WHO water quality guidelines was determined. The WQI was computed to turn multifaceted data obtained from laboratory analyses into simple information that is comprehensible and useable by the public to assess overall quality of water at a specific water points. The GW-chart was used to show hydrogeochemical water types from each sampled site. Microbial analysis revealed that water from 96.3% of shallow wells recorded faecal coliforms ranging from 129 to 920 cfu per 100 ml which were significantly higher than the Malawi Standards and WHO thresholds. In general, shallow well water is of low mineralisation (EC range 80-500 ?S cm-1), with hydrogeochemical facies dominated by Ca-HCO3, which evolves to Ca-Cl water type. The shallow well water registered a WQI range of 50.16-66.04%, with a medium WQ rating. This suggested that the water obtained from the shallow wells is unsuitable for direct human consumption. It was observed that 100% of the shallow wells were at risk of pollution from onsite sanitation because of their proximity to sanitary facilities. It was strongly recommended that onsite treatment interventions have to be mobilised and initiated to protect the households from further possible consequences of using the water.

The stable carbon isotope composition of PM 2.5 and PM 10 in Mexico City Metropolitan Area air  

NASA Astrophysics Data System (ADS)

The sources and distribution of carbon in ambient suspended particles (PM 2.5 and PM 10) of Mexico City Metropolitan Area (MCMA) air were traced using stable carbon isotopes ( 13C/ 12C). Tested potential sources included rural and agricultural soils, gasoline and diesel, liquefied-petroleum gas, volcanic ash, and street dust. The complete combustion of LP gas, diesel and gasoline yielded the lightest ?13C values (-27 to -29‰ vs. PDB), while street dust (PM 10) represented the isotopically heaviest endmember (-17‰). The ?13C values of rural soils from four geographically separated sites were similar (-20.7 ± 1.5‰). ?13C values of particles and soot from diesel and gasoline vehicle emissions and agricultural soils varied between -23 and -26‰. Ambient PM samples collected in November of 2000, and March and December of 2001 at three representative receptor sites of industrial, commercial and residential activities had a ?13C value centered around -25.1‰ in both fractions, resulting from common carbon sources. The predominant carbon sources to MCMA atmospheric particles were hydrocarbon combustion (diesel and/or gasoline) and particles of geological origin. The significantly depleted ?13C values from the industrial site reflect the input of diesel combustion by mobile and point source emissions. Based on stable carbon isotope mass balance, the carbon contribution of geological sources at the commercial and residential sites was approximately 73% for the PM 10 fraction and 54% for PM 2.5. Although not measured in this study, biomass-burning emissions from nearby forests are an important carbon source characterized by isotopically lighter values (-29‰), and can become a significant contributor (67%) of particulate carbon to MCMA air under the prevalence of southwesterly winds. Alternative sources of these 13C-depleted particles, such as cooking fires and municipal waste incineration, need to be assessed. Results show that stable carbon isotope measurements are useful for distinguishing between some carbon sources in suspended particles to MCMA air, and that wind direction has an impact on the distribution of carbon sources in this basin.

Potentiometric surface in the Central Oklahoma (Garber-Wellington) aquifer, Oklahoma, 2009  

USGS Publications Warehouse

A study of the hydrogeology of the Central Oklahoma aquifer was started in 2008 to provide the Oklahoma Water Resources Board (OWRB) hydrogeologic data and a groundwater flow model that can be used as a tool to help manage the aquifer. The 1973 Oklahoma water law requires the OWRB to do hydrologic investigations of Oklahoma's aquifers (termed 'groundwater basins') and to determine amounts of water that may be withdrawn by permitted water users. 'Maximum annual yield' is a term used by OWRB to describe the total amount of water that can be withdrawn from a specific aquifer in any year while allowing a minimum 20-year life of the basin (Oklahoma Water Resources Board, 2010). Currently (2010), the maximum annual yield has not been determined for the Central Oklahoma aquifer. Until the maximum annual yield determination is made, water users are issued a temporary permit by the OWRB for 2 acre-feet/acre per year. The objective of the study, in cooperation with the Oklahoma Water Resources Board, was to study the hydrogeology of the Central Oklahoma aquifer to provide information that will enable the OWRB to determine the maximum annual yield of the aquifer based on different proposed management plans. Groundwater flow models are typically used by the OWRB as a tool to help determine the maximum annual yield. This report presents the potentiometric surface of the Central Oklahoma aquifer based on water-level data collected in 2009 as part of the current (2010) hydrologic study. The U.S. Geological Survey (USGS) Hydrologic Investigations Atlas HA-724 by Christenson and others (1992) presents the 1986-87 potentiometric-surface map. This 1986-87 potentiometric-surface map was made as part of the USGS National Water-Quality Assessment pilot project for the Central Oklahoma aquifer that examined the geochemical and hydrogeological processes operating in the aquifer. An attempt was made to obtain water-level measurements for the 2009 potentiometric-surface map from the wells used for the 1986-87 potentiometric-surface map. Well symbols with circles on the 2009 potentiometric-surface map (fig. 1) indicate wells that were used for the 1986-87 potentiometric-surface map.

Mapping geological at risk areas in the city of São Paulo: issues and results from the largest risk survey in Brazil  

NASA Astrophysics Data System (ADS)

In the City of São Paulo, the first reports of accidents resulting from landslides are directly related to urban expansion that has been recorded since the 30s. Areas of major environmental fragility, such as slopes and stream-banks, have also ended up being occupied without proper planning. The increased number of deaths due to landslides in the 80s already indicated the need for intervention at these sites by the public authorities. It was important to act to prevent these disasters, not only emergency assistance to victimized families. Therefore, in 1989 the first systematic and official survey on the City's at-risk areas was made. At the time, the at-risk sites had been still unknown, except for the occurrence records and press reports. While some areas were evaluated by experts, others appeared or expanded without any control. The surveys pace could not definitely follow the growth and the density of favelas, and some communities started to trigger the first records of accidents in areas hitherto stable. Considering the universe to be studied and the detail level of the work, it was necessary to use specific methodology to enable evaluation of the entire City in a relatively short period of time. For that purpose,mapping activities were carried out in five phases and involved about 80 professionals in the fields of geology, engineering, architecture, geography, civil defense, and housing, who participated directly or indirectly in all stages of work. Thus, the mapping that has recently been completed by the Municipality of São Paulo and by the Institute for Technological Research of São Paulo State is today the largest geological-risk database in the country. Besides technical information, the survey also shows the types of intervention to be implemented according to the degree of risk and the type of verified occupation, vital data to prioritizing the public-authorities actions. Currently, among the 1,602 favelas and informal settlements in the city, 407 (25%) occupy areas with some occurrence probability of mass-movement processes (landslides, erosion, and fall of stone blocks). Together, the assessed areas cover about 13.5 km², which corresponds to about 1% of the City's territory, although they all are located in the outskirts regions. 105,816 homes were analyzed and, currently, 8% of this total is located in the most critical areas, classified as very high risk, which require immediate actions in order to stabilize them; 19% were classified as high risk and the rest - 73% - show more stable situation. Currently, about 115,000 people live in landslide-risk areas in the capital. The results, now complete and current, have been making possible reassessment and adjustment of the low-income intervention projects by the government, prioritizing housing, social-educational infrastructure, and basic-sanitation actions in areas of greatest susceptibility. The program of slum upgrading, the relocation of 5.000 families to safe places and actions participatory monitoring with communities deserves mention and were only possible after the correct diagnosis of risk situations in the city that, despite the large population, has no record deaths from landslides for more than two years.

District heating/cogeneration application studies for the Minneapolis-St. Paul area. Summary of Twin Cities case study and the St. Paul Project  

SciTech Connect

A site-specific study was conducted to evaluate the feasibility of a large, cogeneration/district-heating system for US cities. The MInneapolis-St. Paul area was chosen as the site for a case study of a modern hot-water district-heating system. The first phase of the work was a conceptual feasibility study for the entire metropolitan region. The effort concentrated on assessing the heat loads and heat sources that could be connected over a 20-year period. This study phase set the framework for the overall potential for district heating in the region and was the stimulus for the sceond phase, the St. Paul district-heating demonstration project. The St. P District-Heating Development Company is planning to build the first modern hot-water district-heating system in a major US city.

Seismic vulnerability analysis of moderate seismicity areas using in situ experimental techniques: from the building to the city scale ? Application to Grenoble and Pointe-\\`a-Pitre (France)  

E-print Network

Seismic vulnerability analysis of existing buildings requires basic information on their structural behaviour. The ambient vibrations of buildings and the modal parameters (frequencies, damping ration and modal shapes) that can be extracted from them naturally include the geometry and quality of material in the linear elastic part of their behaviour. The aim of this work is to use this modal information to help the vulnerability assessment. A linear dynamic modal model based on experimental modal parameters is proposed and the fragility curve corresponding to the damage state ?Slight? is built using this model and a simple formula is proposed. This curve is particularly interesting in moderate seismic areas. This methodology is applied to the Grenoble City where ambient vibrations have been recorded in 61 buildings of various types and to the Pointe-\\`a-Pitre City with 7 study-buildings. The fragility curves are developed using the aforementioned methodology. The seismic risk of the study-buildings is discuss...

Spatial distribution of polycyclic aromatic hydrocarbons in Terminalia catappa L. (Combretaceae) bark from a selected heavy road traffic area of Rio de Janeiro City, Brazil.  

PubMed

The levels of 21 polycyclic aromatic hydrocarbons (PAHs) with molecular weights between 128 Da (naphthalene) and 300 Da (coronene) were determined in Terminalia catappa L. (Combretaceae) bark. Tree bark samples were collected in the campus of Oswaldo Cruz Foundation, a green area located in a very intensive traffic area of Rio de Janeiro City, Brazil and about 10 km away from the city center. Samples were submitted to ultrasonic extraction with dichloromethane and analyzed by high-resolution gas chromatography-mass spectrometry. Individual PAH levels varied from 1.23 to 327 ng/g and phenanthrene, fluoranthene and pyrene predominated in all samples. Total PAH levels ranged from 242 to 1640 ng/g with a mean of 628 ng/g. The levels of total PAHs and of total carcinogenic PAHs showed not a clear dependence with tree location and distances to the main routes of that area. No correlation was observed also with PAH levels previously found in total suspended particulate thus indicating that in this area tree bark PAH levels cannot be used to assess their atmospheric levels.

Remotely-Sensed Rainfall for the Wettest Season in Oklahoma on Record  

NASA Astrophysics Data System (ADS)

In the summer of 2007 Oklahoma experienced the wettest June on record, Oklahoma City had 20 consecutive days of reported rainfall (also a record), and damaging flash floods occurred on 15 days. This study analyzes the spatial patterns, temporal variability, and magnitudes of remotely-sensed rainfall from TRMM satellite, PERSIANN-CCS, and the operational rainfall product in the US National Weather Service (NWS) that relies on radar data with adjustments from rain gauges and human quality control. Conclusions drawn from this part of the study will help guide future steps toward integrated, multisensor precipitation estimation as applied to a season of extreme rainfall. The second part of the study applies the rainfall estimates under evaluation to an extreme flash flood case over the heavily instrumented Ft. Cobb basin in Oklahoma. Discharge is simulated and compared to observed streamflow on three subbasins using the NWS's distributed hydrologic model. Results will help determine if satellite-based rainfall estimates can be used, given proper downscaling, as inputs to hydrologic prediction models for extreme, small-scale hydrometeorological events.

University of Oklahoma - High Energy Physics  

SciTech Connect

The High Energy Physics program at the University of Oklahoma, Pat Skubic, Principal Investigator, is attempting to understand nature at the deepest level using the most advanced experimental and theoretical tools. The four experimental faculty, Brad Abbott, Phil Gutierrez, Pat Skubic, and Mike Strauss, together with post-doctoral associates and graduate students, are finishing their work as part of the D0 collaboration at Fermilab, and increasingly focusing their investigations at the Large Hadron Collidor (LHC) as part of the ATLAS Collaboration. Work at the LHC has become even more exciting with the recent discovery by ATLAS and the other collaboration, CMS, of the long-sought Higgs boson, which plays a key role in generating masses for the elementary constituents of matter. Work of the OUHEP group has been in the three areas of hardware, software, and analysis. Now that the Higgs boson has been discovered, completing the Standard Model of fundamental physics, new efforts will focus on finding hints of physics beyond the standard model, such as supersymmetry. The OUHEP theory group (Kim Milton, PI) also consists of four faculty members, Howie Baer, Chung Kao, Kim Milton, and Yun Wang, and associated students and postdocs. They are involved in understanding fundamental issues in formulating theories of the microworld, and in proposing models that carry us past the Standard Model, which is an incomplete description of nature. They therefore work in close concert with their experimental colleagues. One also can study fundamental physics by looking at the large scale structure of the universe; in particular the ``dark energy'' that seems to be causing the universe to expand at an accelerating rate, effectively makes up about 3/4 of the energy in the universe, and yet is totally unidentified. Dark energy and dark matter, which together account for nearly all of the energy in the universe, are an important probe of fundamental physics at the very shortest distances, or at the very highest energies. The outcomes of the group's combined experimental and theoretical research will be an improved understanding of nature, at the highest energies reachable, from which applications to technological innovation will surely result, as they always have from such studies in the past.

Remote Sensing Application to Land Use Classification in a Rapidly Changing Agricultural/Urban Area: City of Virginia Beach, Virginia. Ph.D. Thesis  

NASA Technical Reports Server (NTRS)

Remote sensing data on computer-compatible tapes of LANDSAT 1 multispectral scanner imager were analyzed to generate a land use map of the City of Virginia Beach. All four bands were used in both the supervised and unsupervised approaches with the LAYSYS software system. Color IR imagery of a U-2 flight of the same area was also digitized and two sample areas were analyzed via the unsupervised approach. The relationships between the mapped land use and the soils of the area were investigated. A land use land cover map at a scale of 1:24,000 was obtained from the supervised analysis of LANDSAT 1 data. It was concluded that machine analysis of remote sensing data to produce land use maps was feasible; that the LAYSYS software system was usable for this purpose; and that the machine analysis was capable of extracting detailed information from the relatively small scale LANDSAT data in a much shorter time without compromising accuracy.

Helminth fauna of waterfowl in central Oklahoma.  

PubMed

Free-ranging waterfowl wintering in and migrating through central Oklahoma were collected and examined for intestinal helminths. Seventy-one ducks, including mallards (Anas platyrhynchos), American widgeons (Anas americana), blue-winged teal (Anas discors), and green-winged teal (Anas crecca) were examined; 64 (90.1%) harbored one or more species of metazoa. Six cestodes, 6 trematodes, 6 nematodes, and 1 acanthocephalan were identified, An experimental, non-flying population of ducks was established and monitored to determine the extent of helminth transmission in central Oklahoma. Seven species of helminths were acquired by the sentinel birds during the study. The significance of the parasites recovered and variations in prevalence and species composition of the infections are discussed as they relate to the life cycles of the parasites and the ecology of the hosts.

Largest Dinosaur Ever Discovered Found in Oklahoma  

NSDL National Science Digital Library

Originally discovered in a remote corner of Oklahoma in 1994, the fossil of what may have been the largest creature to ever walk the earth has been excavated by a research team from the University of Oklahoma. Dubbed Sauroposeidon proteles, or "thunder lizard," the dinosaur was almost 100 feet long, with a 39 foot neck and weighing over 50 tons, so big that it would have created minor seismic activity just by walking, according to scientists. The new find is about 110 million years old and consists of neck vertebrae, some almost five feet in length, together with neck ribs nearly twelve feet long. The find is also significant because it may shed light on the last of the North American sauropods, who died out about 100 million years ago. A paper on this new find is scheduled to appear in the Journal of Vertebrate Paleontology. The sites listed provide information and background material about this momentous discovery.

Factors influencing the large-scale distribution of Hg° in the Mexico City area and over the North Pacific  

NASA Astrophysics Data System (ADS)

Gas-phase elemental mercury (Hg°) was measured aboard the NASA DC-8 aircraft during the Intercontinental Chemical Transport Experiment Phase B (INTEX-B) campaign in spring 2006. Flights were conducted around Mexico City and on two subsequent deployments over the North Pacific based out of Honolulu, Hawaii and Anchorage, Alaska. Data obtained from 0.15-12 km altitude showed that Hg° exhibited a relatively constant vertical profile centered around 100 ppqv. Highly concentrated pollution plumes emanating from the Mexico City urban agglomeration revealed that mixing ratios of Hg° as large as 500 ppqv were related to combustion tracers such as CO, but not SO2 which is presumably released locally from coal burning, refineries, and volcanoes. Our analysis of Mexico City plumes indicated that widespread multi-source urban/industrial emissions may have a more important influence on Hg° than specific point sources. Over the Pacific, correlations with CO, CO2, CH4, and C2Cl4 were diffuse overall, but recognizable on flights out of Anchorage and Honolulu. In distinct plumes originating from the Asian continent the Hg°- CO relationship yielded an average value of ~0.56 ppqv/ppbv, in good agreement with previous findings. A prominent feature of the INTEX-B dataset was frequent total depletion of Hg° in the upper troposphere when stratospherically influenced air was encountered. Ozone data obtained with the differential absorption lidar (DIAL) showed that the stratospheric impact on the tropospheric column was a common and pervasive feature on all flights out of Honolulu and Anchorage. We propose that this is likely a major factor driving large-scale seasonality in Hg° mixing ratios, especially at mid-latitudes, and an important process that should be incorporated into global chemical transport models.

Extraction of multilayer vegetation coverage using airborne LiDAR discrete points with intensity information in urban areas: A case study in Nanjing City, China  

NASA Astrophysics Data System (ADS)

Urban vegetation is of a strategic importance for the life quality in the increasing urbanized societies. However, it is still difficult to extract accurately urban vegetation vertical distribution with remote sensing images. This paper presented an effective method to extract multilayer vegetation coverage in urban areas using airborne Light Detection and Ranging (LiDAR) discrete points with intensity information. It was applied in Nanjing City, one of the ecological cities in China. Firstly, a median filtering algorithm based on discrete points was used to restrain high-frequency noise. The airborne LiDAR data intensities of different urban objects were analyzed and obtained three rules, which can distinguish between vegetation and non-vegetation in urban areas, after removing the influence of topography. According to the footprint size and principles of distribution of the point cloud, multilayer vegetation coverage, including trees, shrubs and grass, was achieved by the inverse distance weighting (IDW) interpolation method. The results show that the overall accuracy of the vegetation point classification is 94.57%, which is much accurate than that of the methods in TerraSolid software, through comparing with the investigation in the field and Digital Orthophoto Maps (DOM). This method proposed in our work can be applied to in the extraction of multilayer vegetation coverage in urban area.

Social and demographic determinants for breastfeeding in a rural, suburban and city area of South East China  

PubMed Central

Breastfeeding is a traditional practice in China, yet few studies have explored its current trend after socioeconomic reform. This study aims to characterize breastfeeding rates and possible associations with sociodemographic factors using a breastfeeding questionnaire administered to 1,385 mothers of 6-year-old children. Rates were lowest among city residents and negatively associated with parental and grandmother education levels as well as mothers’ professional occupational status. These findings highlight the impact of urbanization on maternal and child health and the effect of marketing tactics for breast milk substitutes (BMS). Public health education promoting breastfeeding should target urban families, particularly those educated. PMID:24299252

Heavy metals in soils are of great environmental concern, in order to evaluate heavy metal contents and their relationships in the surface soil of industrial area of Baoji city, and also to investigate their influence on the soils. Soil samples were collected from 50 sites, and the concentration of Pb, Zn, Cu, Cr, Ni heavy metals and the contents of characteristics in soil from industrial area of Baoji city were determined with X-ray fluorescence method. The concentrations of Pb, Zn, Cu, Cr and Ni in the investigated soils reached the amount of 2,682.00-76,979.42, 169.30-8,288.58, 62.24-242.36, 91.96-110.54 and 36.14-179.28 mg kg-1, respectively. The major element Pb contents of the topsoils were determined. to highlight the influence of ‘anthropic’ features on the heavy metal concentrations and their distributions. To compare, all values of elements were much higher than those of unpolluted soils in the middle of Shaanxi province that average 16.0-26.5, 67.1-120.0, 17.8-57.0, 46.9-65.6 and 24.7-34.6 mg kg-1 for Pb, Zn, Cu, Cr and Ni, respectively. An ensemble of basic and relativity analysis was performed to reduce the precipitate of Pb in soil was extremely high and greatly relativity with other elements. Meanwhile, Pb, Zn, Cu, Cr, Ni heavy metals were typical elements of anthropic activities sources, so it was easy to infer to the tracers of anthropic pollutions from the factorial analysis, which was coming from the storage battery manufactory pollutions. The pollutant distributions were constructed for the urban area which identified storage battery manufactory soot precipitate as the main source of diffuse pollution and also showed the contribution of the topsoils of industrial area of Baoji city as the source point of pollution. Consequently, the impact of heavy metals on soil was proposed and discussed. These results highlight the need for instituting a systematic and continuous monitoring of heavy metals and other forms of pollutants in Baoji city to ensure that pollution does not become a serious problem in the future.

Trypanosoma cruzi infection in a dog from Oklahoma.  

PubMed

A dog with signs of weakness, labored breathing, and generalized edema was examined. It was heavily infested with fleas and had wounds resulting from a recent fight. Hematologic findings were not remarkable, except for parasites in the blood. The dog was treated for fleas and given antibiotics, but was euthanatized when it failed to respond. Blood and tissue specimens were found to contain Trypanosoma cruzi, and the serum contained antibodies to the organism. We believe this is the first confirmed case of T cruzi infection in dogs from Oklahoma. The public health implications of this finding are underscored by a report on the detection of T cruzi in raccoons in the same season and geographic area. PMID:3098711

Aerosol size distribution and seasonal variation in an urban area of an industrial city in central India.  

PubMed

To study the size distribution and seasonal variations of atmospheric aerosols, size-segregated aerosol samples were collected from July 2009 to June 2010 using the nine-stage cascade impactor aerosol sampler in Durg City, India. The aerosol particles exhibited bimodal size distribution on mass concentration with a peak at 2.5-4.4 ?m size ranges in the coarse mode and 2.1-2.5 ?m size ranges in the fine mode. The aerosol mass and size distribution during monsoon were found unimodal distribution with a peak in the coarse mode, while they showed trimodal distributions during winter with all three peaks appearing in the fine mode. The annual mean concentration of PM(10) aerosol was found to be 253.5 ± 99.4 ?g/m(3), which is four times higher as compared to the annual guideline of National Ambient Air Quality Standards (NAAQS) of India prescribed by the Central Pollution Control Board (CPCB), India. The highest aerosol mass concentrations were found during winter due to enormous biomass burning, while the lowest concentrations were observed during monsoon due to heavy rainfall. Air quality index values calculated in this study showed that 35% of the days were unhealthy for sensitive people, 35% were unhealthy or very unhealthy, while 3.3% were found as hazardous in Durg City, India.

Heavy Metals in Soil and Crops of an Intensively Farmed Area: A Case Study in Yucheng City, Shandong Province, China  

PubMed Central

Yucheng City is located in northwestern Shandong Province, China, and is situated on the Huang-Huai-Hai Plain, the largest alluvial plain in China. In this study, 86 surface soil samples were collected in Yucheng City and analyzed for cation exchange capacity (CEC), soil organic matter (SOM), pH, available phosphorus (avail. P), phosphorus (P), aluminum (Al), and iron (Fe). These soils were also analyzed for ‘total’ chromium (Cr), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), mercury (Hg), cadmium (Cd), and lead (Pb), together with 92 wheat samples and 37 corn samples. There was no obvious heavy metal contamination in the soil and irrigation water. But the long-term accumulation of heavy metals in soil has lead to an increase of Ni, As, Hg and Pb concentrations in some of wheat and corn samples and Cd in wheat samples. Because of the numerous sources of soil heavy metals and the lower level of heavy metal in irrigation water, there is no significant relation between soil heavy metal concentrations and irrigation water concentrations. Cr, Ni were mainly from the indigenous clay minerals according to multivariate analysis. Little contribution to soil heavy metal contents from agricultural fertilizer use was found and the local anomalies of As, Cd, Hg, Pb in wheat and corn grain are attributed to the interactive effects of irrigation and fertilizer used. Aerial Hg, however may also be the source of Hg for soil, wheat and corn. PMID:20616981

Determination of reserves of methane from coal beds for use in rural communities in eastern Oklahoma  

SciTech Connect

Coal-bed methane has been classified as an unconventional source of gas by the U.S. Congress, and it has no Federal price limit. Thus, it is attracting considerable interest concerning its reserves, potential recovery, and use. Previous work in Oklahoma showed that approx. 1.3 tcf of identified coal-bed-methane resources is present in Haskell and Le Flore counties. Thus, the present study was undertaken to determine the feasibility of using methane from coal beds in rural areas in East Oklahoma, and to recommend general locations in which to drill from 500 to 1,800 ft deep to selected coal beds for methane production. Coal-bed-methane reserves have been identified in the Hartshorne coals (Desmoinesian) in the vicinities of Spiro and Poteau in Le Flore County and of Keota in Haskell County, all in the Arkoma Basin. These areas are recommended for exploratory drilling and production of coal-bed methane. 21 references.

Bridging the gap between traffic generated health stressors in urban areas: predicting xylene levels in EU cities.  

PubMed

Many citizens live, work, commute, or visit traffic intensive spaces and are exposed to high levels of chemical health stressors. However, urban conurbations worldwide present monitoring "shortage" - due to economical and/or practical constraints - for toxic stressors such as xylene isomers, which can pose human health risks. This "shortage" may be covered by the establishment of associations between rarely monitored substances such as xylenes and more frequently monitored (i.e. benzene) or usually monitored (i.e. CO). Regression analysis is used and strong statistical relationships are detected. The adopted models are applied to EU cities and comparison between measurements and predictions depicts their representativeness. The analysis provides transferability insights in an effort to bridge the gap between traffic-related stressors. Strong associations between substances of the air pollution mixture may be influential to interpret the complexity of the causal chain, especially if a synergetic exposure assessment in traffic intensive spaces is considered.

Linearly Organized Turbulence Structures Observed Over a Suburban Area by Dual-Doppler Lidar  

SciTech Connect

Dual-Doppler lidar observations are used to investigate the structure and evolution of surface layer flow over a suburban area. The observations were made during the Joint Urban 2003 (JU2003) field experiment in Oklahoma City in the summer of 2003. This study focuses specifically on a 10-hour sequence of scan data beginning shortly after noon local time on July 7, 2003. During this period two coherent Doppler lidars performed overlapping low elevation angle sector scans upwind and south of Oklahoma City’s central business district (CBD). Radial velocity data from the two lidars are processed to reveal the structure and evolution of the horizontal velocity field in the surface layer throughout the afternoon and evening transition periods. The retrieved velocity fields clearly show a tendency for turbulence structures to be elongated in the direction of the mean flow throughout the entire 10-hour study period. As the stratification changed from unstable to weakly stable the turbulence structures became increasingly more linearly organized, and the cross-stream separation between high- and low-speed regoins decreased. The spatially resolved velocity fields are used to estimate streamwise and cross-stream turbulence length scales as functions of stability.

Integration of data from censuses and remote sensing to measure the socio-economic and environmental evolution in urban areas: case of the city of Sherbrooke (1981-2006)  

NASA Astrophysics Data System (ADS)

The urban environment is complex, heterogeneous and temporally changeable. Man is the main actor in the transformation of urban areas where he interacts with intensity. Spatial differentiation is a result of human occupation in the urban environment. This occupation may vary according to land use, population density, social and economic characteristics and environment. This leads us to say that the socio-economic and environmental indicators change according to the various locations in the urban area and through time. Our goal is to measure the socio-economic and environmental changes in the urban area of the city of Sherbrooke using remote sensing data synchronized with the censuses and that we will then integrate into the geographic information system (GIS). We have used data from the 1981 and 2006 censuses, 1983 aerial photos, 2007 orthophotos and 1983 MSS and 2006 Ikons satellite images to measure the socio-economic and environmental changes in the city of Sherbrooke. We have used spatial analysis tools to integrate image data with census data. The methods uses such as global indices, principal component analysis combined with the variation between the two dates have yielded interesting results. The first factor in principal component analysis with orthogonal rotation (Varimax) justified a substantial percentage of the variance in global indices. The use of dissemination areas resulted in detailed information on the change in the city. From the perspective of spatial distribution, we noted a major difference between the central areas and the peripheral areas in 1981 and 2006. From the perspective of evolution between 1981 and 2006, we observed that are positive and negative changes at various levels took place. We also observed the evolution of ethnicity in the Sherbrooke city and Lennoxville municipality. The study showed that the French population is prevalent in the old city of Sherbrooke as the English population is prevalent in Lennoxville. The European population is spread over the two cities. The aboriginal population is well distributed over the city of Sherbrooke. The population from Asian and Oceanic backgrounds are concentrated (sometimes on an exclusive basis) in the north and west-centre area of Jardins-Fleuris, in the eastern area of l'Assomption, the northeastern area of Sainte-Famille and the center area of Marie-Reine. We also find concentrations of immigrant populations from all backgrounds in areas such as in the southern part of the Immaculee-Conception and Saint-Joseph and in the south-eastern part of Sainte-Jeanne-d'Arc. This indicates that ethnic neighborhoods are taking roots in the city of Sherbrooke. Keywords : socio-economic and environmental, urban, remote sensing, multiple factor analysis, dissemination areas, the city of Sherbrooke, Lennoxville municipality.

Hydrogeologic data from a 2,000-foot deep core hole at Polk City, Green Swamp area, central Florida  

USGS Publications Warehouse

Two core holes were drilled to depths of 906 and 1,996 feet, respectively, within the Tertiary limestone (Floridan) aquifers, at Polk City, central Florida. Data from the two holes revealed that the bottom of the zone of vigorous groundwater circulation is confined by carbonate rocks at a depth of about 1,000 feet (863 feet below sea level). The zone of circulation is divided into two high-permeability zones. The dissolved solids of the water within the high-permeability zones is approximately 150 milligrams per liter. Within the carbonate rocks, the dissolved solids content of the water reaches about 2,000 milligrams per liter at the bottom of the core hole. Water levels in the core holes declined a total of about 16 feet as the hole was drilled; most of the head loss occurred at depths below 1,800 feet. The porosities of selected cores ranged from 1.6 to 45.3 percent; the hydraulic conductivities ranged from less than 0.000024 to 19.0786 feet per day in the horizontal direction and from less than 0.000024 to 2.99 feet per day in the vertical direction; and the ratio of vertical to horizontal permeability ranged from 0.03 to 1.98. Due to drilling problems, packer tests and geophysical logging could not be accomplished. (USGS)

Aerial radiological survey of the Turkey Point Plant and surrounding area, Florida City, Florida. Date of survey: March 1983  

SciTech Connect

The aerial survey of the Turkey Point Plant covered a 140-square-kilometer (55-square-mile) area that included the reactor facility and an area of cooling channels located immediately south of the reactor facilities. The reactor and cooling channels were on the eastern edge of the survey area. The survey was conducted during the period 18 to 26 March 1983. Inferred exposure rates, except over the site, were due primarily to naturally occurring gamma ray emitting radionuclides and cosmic ray activity (estimated at 3.1 ..mu..R/h). The exposure rates varied from 3 to 6 ..mu..R/h in background areas; the most frequently occurring range was 3 to 4 ..mu..R/h. The maximum inferred exposure rate over the site was 140 ..mu..R/h. Spectral analysis revealed cobalt-60 as the primary contributor to the elevated exposure rate over the reactor facilities. Results of ground-based measurements taken at four locations within the survey area were consistent with the aerial data. Data collected during this survey were also consistent with results from a previous survey conducted in April 1972. 3 references, 8 figures, 3 tables.

Coupling high-resolution hydraulic and hydrologic models for flash flood forecasting and inundation mapping in urban areas - A case study for the City of Fort Worth  

NASA Astrophysics Data System (ADS)

With many diverse features such as channels, pipes, culverts, buildings, etc., hydraulic modeling in urban areas for inundation mapping poses significant challenges. Identifying the practical extent of the details to be modeled in order to obtain sufficiently accurate results in a timely manner for effective emergency management is one of them. In this study we assess the tradeoffs between model complexity vs. information content for decision making in applying high-resolution hydrologic and hydraulic models for real-time flash flood forecasting and inundation mapping in urban areas. In a large urban area such as the Dallas-Fort Worth Metroplex (DFW), there exists very large spatial variability in imperviousness depending on the area of interest. As such, one may expect significant sensitivity of hydraulic model results to the resolution and accuracy of hydrologic models. In this work, we present the initial results from coupling of high-resolution hydrologic and hydraulic models for two 'hot spots' within the City of Fort Worth for real-time inundation mapping.

Naturally occurring hepatozoonosis in coyotes from Oklahoma.  

PubMed

Nine of 16 free-ranging coyotes (Canis latrans) from central Oklahoma (USA) had naturally acquired infections of Hepatozoon americanum. Infections were confirmed by recognition of tissue stages closely resembling H. americanum in skeletal and cardiac muscle. At the time coyotes were collected they were infested with a variety of ticks, including adult Gulf Coast ticks (Amblyomma maculatum). We propose that the high prevalence of H. americanum in this small sample of free-ranging coyotes and the ability of these same animals to harbor adult populations of A. maculatum is an important component of the epizootiology of canine hepatozoonosis in North America.

Land use pattern, socio-economic development, and assessment of their impacts on ecosystem service value: study on natural wetlands distribution area (NWDA) in Fuzhou city, southeastern China.  

PubMed

This paper quantifies the allocation of ecosystem services value (ESV) associated with land use pattern and qualitatively examined impacts of land use changes and socio-economic factors on spatiotemporal variation of ESV in the Natural Wetland Distribution Area (NWDA), Fuzhou city, China. The results showed that total ESV of the study area decreased from 4,332.16 × 10(6) RMB Yuan in 1989 to 3,697.42 × 10(6) RMB Yuan in 2009, mainly due to the remarkable decreases in cropland (decreased by 55.3 %) and wetland (decreased by 74.2 %). Forest, water, and wetland played major roles in providing ecosystem services, accounting for over 90 % of the total ESV. Based on time series Landsat TM/ETM+ imagery, geographic information system, and historical data, analysis of the spatiotemporal variation of ESV from 1989 to 2009 was performed. It indicated that rapid expansion of urban areas along the Minjiang River resulted in significant changes in land use types, leading to a dramatic decline in ecosystem services. Meanwhile, because of land scarcity and unique ecosystem functions, the emergency of wetland and cropland protection in built-up area has become an urgent task of local authorities to the local government. Furthermore, there was still a significant negative correlation between ESV of cropland and wetland and the GDP. The results suggest that future planning of land use pattern should control encroachment of urban areas into cropland and wetland in addition to scientific and rational policies towards minimizing the adverse effects of urbanization.

Assessment of the risk of introduction of Anoplophora glabripennis (Coleoptera: Cerambycidae) in municipal solid waste from the quarantine area of New York City to landfills outside of the quarantine area: a pathway analysis of the risk of spread and establishment.  

PubMed

The risk associated with spread of Asian longhorned beetle, Anoplophora glabripennis (Motschulsky), from infested areas in New York City to the wide array of landfills across the eastern United States contracted by the city since 1997 was unknown, but of great concern. Landfills, some as far as South Carolina, Virginia, and Ohio, occupied forest types and climates at high risk of Asian longhorned beetle establishment. The city proposed a separate waste wood collection known as the "311 System;" this was estimated to cost federal and state agencies $6.1 to $9.1 million per year, including the cost of processing and disposal of the wood. Pathway analysis was used to quantify the probability that Asian longhorned beetle present in wood waste collected at curbside would survive transport, compaction, and burial to form a mated pair. The study found that in seven alternate management scenarios, risks with most pathways are very low, especially given existing mitigations. Mitigations included chemical control, removal of infested trees, and burial of wood waste in managed landfills that involved multiple-layering, compaction, and capping of dumped waste with a 15-cm soil cover at the end of each day. Although the risk of business-as-usual collection and disposal practices was virtually nil, any changes of policy or practice such as illegal dumping or disposal at a single landfill increased the risk many thousandfold. By rigorously maintaining and monitoring existing mitigations, it was estimated that taxpayers would save $75 to $122 million dollars over the next decade. PMID:15770756

Contributing recharge areas, groundwater travel time, and groundwater water quality of the Missouri River alluvial aquifer near the City of Independence, Missouri, well field, 1997-2008  

USGS Publications Warehouse

The City of Independence, Missouri, operates a well field in the Missouri River alluvial aquifer. Contributing recharge areas (CRA) were last determined for the well field in 1996. Since that time, eight supply wells have been installed in the area north of the Missouri River and well pumpage has changed for the older supply wells. The change in pumping has altered groundwater flow and substantially changed the character of the CRA and groundwater travel times to the supply wells. The U.S Geological Survey, in a cooperative study with the City of Independence, Missouri, simulated steady-state groundwater flow for 2007 well pumpage, average annual river stage, and average annual recharge. Particle-tracking analysis was used to determine the CRA for supply wells and monitoring wells, and the travel time from recharge areas to supply wells, recharge areas to monitoring wells, and monitoring wells to supply wells. The simulated CRA for the well field is elongated in the upstream direction and extends to both sides of the Missouri River. Groundwater flow paths and recharge areas estimated for monitoring wells indicate the origin of water to each monitoring well, the travel time of that water from the recharge area, the flow path from the vicinity of each monitoring well to a supply well, and the travel time from the monitoring well to the supply well. Monitoring wells 14a and 14b have the shortest groundwater travel time from their contributing recharge area of 0.30 years and monitoring well 29a has the longest maximum groundwater travel time from its contributing recharge area of 1,701 years. Monitoring well 22a has the shortest groundwater travel time of 0.5 day to supply well 44 and monitoring well 3b has the longest maximum travel time of 31.91 years to supply well 10. Water-quality samples from the Independence groundwater monitoring well network were collected from 1997 to 2008 by USGS personnel during ongoing annual sampling within the 10-year contributing recharge area (CRA) of the Independence well field. Statistical summaries and the spatial and temporal variability of water quality in the Missouri River alluvial aquifer near the Independence well field were characterized from analyses of 598 water samples. Water-quality constituent groups include dissolved oxygen and physical properties, nutrients, major ions and trace elements, wastewater indicator compounds, fuel compounds, and total benzene, toluene, ethylbenzene, and xylene (BTEX), alachlor, and atrazine. The Missouri Secondary Maximum Contaminant Level (SMCL) for iron was exceeded in almost all monitoring wells. The Missouri Maximum Contaminant Level (MCL) for arsenic was exceeded 32 times in samples from monitoring wells. The MCL for barium was exceeded five times in samples from one monitoring well. The SMCL for manganese was exceeded 160 times in samples from all monitoring wells and the combined well-field sample. The most frequently detected wastewater indicator compounds were N,N-diethyl-meta-toluamide (DEET), phenol, caffeine, and metolachlor. The most frequently detected fuel compounds were toluene and benzene. Alachlor was detected in 22 samples and atrazine was detected in 37 samples and the combined well-field sample. The MCL for atrazine was exceeded in one sample from one monitoring well. Samples from monitoring wells with median concentrations of total inorganic nitrogen larger than 1 milligram per liter (mg/L) are located near agricultural land and may indicate that agricultural land practices are the source of nitrogen to groundwater. Largest median values of specific conductance; total inorganic nitrogen; dissolved calcium, magnesium, sodium, iron, arsenic, manganese, bicarbonate, and sulfate and detections of wastewater indicator compounds generally were in water samples from monitoring wells with CRAs that intersect the south bank of the Missouri River. Zones of higher specific conductance were located just upstream from the Independen

Procedural modeling of cities  

Microsoft Academic Search

Modeling a city poses a number of problems to computer graphics. Every urban area has a transportation network that follows population and environmental influences, and often a superimposed pattern plan. The buildings appearances follow historical, aesthetic and statutory rules. To create a virtual city, a roadmap has to be designed and a large number of buildings need to be generated.

Reproducing in Cities  

Microsoft Academic Search

Reproducing in cities has always been costly, leading to lower fertility (that is, lower birth rates) in urban than in rural areas. Historically, although cities provided job opportunities, initially residents incurred the penalty of higher infant mortality, but as mortality rates fell at the end of the 19th century, European birth rates began to plummet. Fertility decline in Africa only

Evaluation of the volatility basis-set approach for the simulation of organic aerosol formation in the Mexico City metropolitan area  

NASA Astrophysics Data System (ADS)

New primary and secondary organic aerosol modules have been added to PMCAMx, a three dimensional chemical transport model (CTM), for use with the SAPRC99 chemistry mechanism based on recent smog chamber studies. The new modelling framework is based on the volatility basis-set approach: both primary and secondary organic components are assumed to be semivolatile and photochemically reactive and are distributed in logarithmically spaced volatility bins. This new framework with the use of the new volatility basis parameters for low-NOx and high-NOx conditions tends to predict 4-6 times higher anthropogenic SOA concentrations than those predicted with the older generation of models. The resulting PMCAMx-2008 was applied in Mexico City Metropolitan Area (MCMA) for approximately a week during April 2003 during a period of very low regional biomass burning impact. The emission inventory, which uses as a starting point the MCMA 2004 official inventory, is modified and the primary organic aerosol (POA) emissions are distributed by volatility based on dilution experiments. The predicted organic aerosol (OA) concentrations peak in the center of Mexico City, reaching values above 40 ?g m-3. The model predictions are compared with the results of the Positive Matrix Factorization (PMF) analysis of the Aerosol Mass Spectrometry (AMS) observations. The model reproduces both Hydrocarbon-like Organic Aerosol (HOA) and Oxygenated Organic Aerosol (OOA) concentrations and diurnal profiles. The small OA underprediction during the rush-hour periods and overprediction in the afternoon suggest potential improvements to the description of fresh primary organic emissions and the formation of the oxygenated organic aerosols, respectively, although they may also be due to errors in the simulation of dispersion and vertical mixing. However, the AMS OOA data are not specific enough to prove that the model reproduces the organic aerosol observations for the right reasons. Other combinations of contributions of primary and secondary organic aerosol production rates may lead to similar results. The model results strongly suggest that, during the simulated period, transport of OA from outside the city was a significant contributor to the observed OA levels. Future simulations should use a larger domain in order to test whether the regional OA can be predicted with current SOA parameterizations. Sensitivity tests indicate that the predicted OA concentration is especially sensitive to the volatility distribution of the emissions in the lower volatility bins.

Flash floods and debris flow in the city area of Messina, north-east part of Sicily, Italy in October 2009: the case of the Giampilieri catchment  

NASA Astrophysics Data System (ADS)

This paper concerns the analysis of the 1 October 2009 flash flood and debris flow event caused by a very intense rainfall concentrated over the Messina area. The storm caused severe flash floods in many villages around the city of Messina, such as Giampilieri, Scaletta Zanclea, Altolia Superiore and Molino, with 38 casualties and significant damages to property, buildings, roads and bridges estimated close to 550 million Euro. The main focus of this work is to perform a post event analysis, putting together available meteorological and hydrological data in order to get better insight into temporal and spatial variability of the rain storm, the soil moisture conditions and the consequent flash flood in the Giampilieri catchment. The event was investigated using observed data from a raingauge network. Statistical analysis using GEV distribution was performed and rainfall return period (storm severity) was estimated. Further, measured rainfall data and rainfall-runoff modelling were used to estimate soil moisture conditions, to analyse the hydrological behaviour and to reconstruct flood hydrograph. With the help of GIS technology and particularly spatial analysis, the volume of debris which has gone down into the Giampilieri village was also calculated. GIS maps with landslide and material deposit areas were produced and analysed.

Relationship between pulmonary function and indoor air pollution from coal combustion among adult residents in an inner-city area of southwest China.  

PubMed

Few studies evaluate the amount of particulate matter less than 2.5 mm in diameter (PM2.5) in relation to a change in lung function among adults in a population. The aim of this study was to assess the association of coal as a domestic energy source to pulmonary function in an adult population in inner-city areas of Zunyi city in China where coal use is common. In a cross-sectional study of 104 households, pulmonary function measurements were assessed and compared in 110 coal users and 121 non-coal users (?18 years old) who were all nonsmokers. Several sociodemographic factors were assessed by questionnaire, and ventilatory function measurements including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), the FEV1/FVC ratio, and peak expiratory flow rate (PEFR) were compared between the 2 groups. The amount of PM2.5 was also measured in all residences. There was a significant increase in the relative concentration of PM2.5 in the indoor kitchens and living rooms of the coal-exposed group compared to the non-coal-exposed group. In multivariate analysis, current exposure to coal smoke was associated with a 31.7% decrease in FVC, a 42.0% decrease in FEV1, a 7.46% decrease in the FEV1/FVC ratio, and a 23.1% decrease in PEFR in adult residents. The slope of lung function decrease for Chinese adults is approximately a 2-L decrease in FVC, a 3-L decrease in FEV1, and an 8 L/s decrease in PEFR per count per minute of PM2.5 exposure. These results demonstrate the harmful effects of indoor air pollution from coal smoke on the lung function of adult residents and emphasize the need for public health efforts to decrease exposure to coal smoke.

Separation of Emitted and Photochemical Formaldehyde in the Mexico City Metropolitan Area using a Statistical Analysis and a New Pair of Gas-phase Tracers  

NASA Astrophysics Data System (ADS)

In urban air, the presence of formaldehyde (HCHO) is the result of direct emissions from mobile sources (primary HCHO) and of its production by photochemical oxidation of volatile organic compounds (VOC) in the atmosphere (secondary HCHO). HCHO is a known carcinogen, and is further capable to jump-start photochemical smog formation. Pollution control strategies require deconvolution of the amounts of HCHO formed from primary and secondary sources. To separate primary, secondary and background HCHO, a statistical regression analysis of the time series of HCHO from pairs of gas-phase tracer molecules was undertaken. Carbon monoxide (CO) was used as tracer for primary sources; Two different species were compared as tracers for secondary HCHO: glyoxal (CHOCHO) and ozone (O3). These time series were measured at the field campaign supersite located at the National Center for Environmental Research and Training (CENICA) in the Mexico City Metropolitan Area during the MCMA-2003 campaign. In addition, background HCHO measurements were performed outside the city. Correlation coefficients were highest for the CHOCHO-CO tracer pair, indicating that CHOCHO is a better tracer for secondary sources than O3, used previously for this purpose. Results of the analysis are presented for the pre-Easter, Easter week and post-Easter periods. Further, the effect of temperature on the primary and secondary HCHO sources is assessed. On a 24-hour average basis, secondary sources dominate over primary sources. However, during sunrise, when HCHO acts as a radical source to jump-start photochemistry, a significant amount of the HCHO is associated with primary emissions.

Remote Sensing of Glyoxal as a New Atmospheric Tracer for VOC Chemistry and Secondary Organic Aerosol Formation in the Mexico City Metropolitan Area  

NASA Astrophysics Data System (ADS)

Air pollution in the Mexico City Metropolitan Area (MCMA) is intimately linked with the photochemical transformation of primary pollutants like VOC (volatile organic compounds) and NOx, which gives rise to the formation of secondary pollutants such as ozone and secondary organic aerosol (SOA) and their associated adverse effects on human health. As part of the field campaign held in the MCMA in April/May 2003, state-of-the-art measurement techniques including open-path Differential Optical Absorption Spectroscopy (DOAS), spectroradiometry, Aerosol Mass Spectrometry (AMS) and Laser Induced Fluorescence (LIF) were located at the National Center for Environmental Research and Training (CENICA) in Mexico City to characterize the gas-phase and aerosol-phase composition of relevance to the formation of ozone and SOA. A first-ever spectroscopic detection of glyoxal (DOAS) in the atmosphere is described. Glyoxal is shown to be a very useful new photochemical tracer for the chemistry of VOC. The time-resolved glyoxal measurements reveal a very efficient VOC oxidation process during morning hours, which is found to be relevant for overall smog formation later in the day. In combination with measurements of the radical precursor substances HONO, HCHO, ozone (DOAS), their respective J-values (spectroradiometry), OH- and HO2-radical concentrations (LIF), speciated aromatic hydrocarbons (DOAS) and chemical composition of the aerosol phase (AMS), the glyoxal data enables assessment of the role of VOC oxidation in the formation of secondary pollutants in the gas- and aerosol-phase by placing a lower limit on the extend of VOC turnover.

SFC to cease operations at Gore, Oklahoma  

SciTech Connect

On February 16, Sequoyah Fuels Corporation (SFC) formally notified the Nuclear Regulatory Commission it intends to terminate operations and commence decommissioning at its uranium conversion facility at Gore, Oklahoma. SFC officially requested that its NRC operating license be terminated July 31, 1993. SFC, a wholly-owned subsidiary of General Atomics Corporation (GA), will be responsible for the estimated $21.2-million decommissioning plan. GA has contended that it is not financially liable for the cleanup but stated it would be available to offer financial assistance if needed. Over the proposed 10-year cleanup schedule, GA said SFC can finance the decommissioning by drawing on SFC's estimated $70-million in revenue from a fee-for-contract agreement in its recently formed joint-venture with AlliedSignal Inc., called ConverDyn.

NASA Technical Reports Server (NTRS)

Soil moisture data collected in conjunction with aircraft sensor and SEASAT SAR data taken near Guymon, Oklahoma are summarized. In order to minimize the effects of vegetation and roughness three bare and uniformly smooth fields were sampled 6 times at three day intervals on the flight days from August 2 through 17. Two fields remained unirrigated and dry. A similar pair of fields was irrigated at different times during the sample period. In addition, eighteen other fields were sampled on the nonflight days with no field being sampled more than 24 hours from a flight time. The aircraft sensors used included either black and white or color infrared photography, L and C band passive microwave radiometers, the 13.3, 4.75, 1.6 and .4 GHz scatterometers, the 11 channel modular microwave scanner, and the PRT5.
