    Background: Regarding the importance of air pollution issue for large cities, as Tehran metropolis, many plans, programs, projects and regulations have been developed to manage urban air pollution. However, most of them failed to decline the pollution. The purpose of this study is to pathologically analyze air-pollution control plans in order to offer effective solutions for Tehran metropolis. Methods: A qualitative content analysis and a semi-structured interview with 14 practicing professionals were used to identify key causes and sources of Tehran's air pollution, to recognize challenges and obstacles towards effective performance of air-pollution control plans in this metropolitan area, and to suggest the most effective controlling solutions. Results: Challenges related to air-pollution control plans can be divided into two major categories: Firstly lack of integrated and organized stewardship and secondly those related to political, economical, social and technical environmental abbreviated as PEST, challenges. For effective control of the Tehran air pollution, the following eight controlling alternatives were identified: Systematization of plan preparation process, organizing the stewardship, standardization and utilization of new technologies and professional experts, cultural and infrastructural development, realization of social justice, developing coordination and controlling mechanisms, improving citizen's participatory capacity, and focusing on effective management of fuel and energy. Conclusions: Controlling air pollution in Tehran should be considered as a priority for policymakers to make enforcements through applying a systemic cycle of preparation effective and comprehensive plans. Further, implement the enforcements and evaluate the environmental impact of the plans through involving all stakeholders. PMID:24130939

    Short-term exposure to particulate matter (PM) air pollution is associated with an increased cardiovascular mortality. Chronic exposure to PM is also associated with cardiovascular risk. Myocardial infarction and heart failure are the most common cardiovascular events associated with PM pollution. The pathophysiological mechanisms related to PM pollution are inflammation, thrombosis, vasomotion abnormalities, progression of atherosclerosis, increased blood pressure, and cardiac remodeling. A decrease in PM exposure may be particularly beneficial in subjects with a high cardiovascular risk. PMID:26547674

    Clifton, Marjorie

    1964-01-01

    Dr Marjorie Clifton describes the classification of gaseous and nongaseous constituents of air pollution and then outlines the methods of measuring these. The National Survey embraced 150 towns of all sizes throughout England and Wales and provided data on smoke and sulphur dioxide in relation to climate, topography, industrialization, population density, fuel utilization and urban development. Dr W C Turner discusses the relationship between air pollution and mortality from respiratory conditions, and particularly the incidence of chronic bronchitis. He postulates a theory that such respiratory conditions arise as an allergy to the spores of certain moulds, spore formation being encouraged by the air humidity in Greatv Britain and overcrowded and damp living conditions. He describes the results of a twenty-week study undertaken in 1962-3, showing associations between respiratory disease and levels of air pollution. Dr Stuart Carne undertook a survey in general practice to plot the patterns of respiratory illness in London during the winter of 1962-3. There were two peaks of respiratory illnesses coinciding with the fog at the beginning of December and the freeze-up from the end of December until the beginning of March. PMID:14178955

    Abstract Background The centralization of human activities is associated with different pollutants which enter into environment easily and cause the urban environment more vulnerable. Regarding the importance of air pollution issue for Tehran metropolis, many plans and regulations have been developed. However, most of them failed to decline the pollution. The purpose of this study was to pathologically analyze air-pollution control plans to offer effective solutions for Tehran metropolis. Methods A Qualitative content analysis in addition to a semi-structured interview with 14 practicing professional were used to identify 1) key sources of Tehran’s air pollution, 2) recognize challenges towards effective performance of pertinent plans and 3), offer effective solutions. Results Related challenges to air-pollution control plans can be divided into two major categories including lack of integrated and organized stewardship and PEST challenges. Conclusion For controlling the air pollution of Tehran effectively, various controlling alternatives were identified as systematization of plan preparation process, standardization and utilization of new technologies & experts, infrastructural development, realization of social justice, developing coordination mechanisms, improving citizens’ participatory capacity and focusing on effective management of fuel and energy. Controlling air pollution in Tehran needs a serious attention of policymakers to make enforcements through applying a systemic cycle of preparation comprehensive plans. Further, implement the enforcements and evaluate the environmental impact of the plans through involving all stakeholders. PMID:26171340

    2000-01-01

    This review presents a brief overview of the health effects and exposures of two criteria pollutants--ozone and particulate matter--and two toxic air pollutants--benzene and formaldehyde. These pollutants were selected from the six criteria pollutants and from the 189 toxic air pollutants on the basis of their prevalence in the United States, their physicochemical behavior, and the magnitude of their potential health threat. The health effects data included in this review primarily include results from epidemiologic studies; however, some findings from animal studies are also discussed when no other information is available. Health effects findings for each pollutant are related in this review to corresponding information about outdoor, indoor, and personal exposures and pollutant sources.

    PubMed Central

    Balmes, John R.; Collard, Harold R.

    2015-01-01

    Air pollution exposure is a well-established risk factor for several adverse respiratory outcomes, including airways diseases and lung cancer. Few studies have investigated the relationship between air pollution and interstitial lung disease (ILD) despite many forms of ILD arising from environmental exposures. There are potential mechanisms by which air pollution could cause, exacerbate, or accelerate the progression of certain forms of ILD via pulmonary and systemic inflammation as well as oxidative stress. This article will review the current epidemiologic and translational data supporting the plausibility of this relationship and propose a new conceptual framework for characterizing novel environmental risk factors for these forms of lung disease.

    SciTech Connect

    1989-08-01

    Bethlehem Steel Corporation and the Maryland Department of the Environment have announced an agreement under which Bethlehem will spend an estimated $92-million at its Sparrows Points, Md., plant for technologically-advanced controls to further reduce air and water pollution, mainly from the plant's coke ovens. The two major systems include one to treat by-product coke oven gas and chemicals, and another to upgrade existing pushing emission controls on two older coke oven batteries. One of the new systems will replace most of the existing equipment that cleans gas and treats chemicals created by the coking process at the plant's three coke oven batteries. Because this system has the potential to greatly reduce sulfur dioxide and other pollutants, the United States Department of Energy (DOE) in September announced that its installation qualified for funding as part of the nationwide Innovative Clean Coal Technology Program.

  6. A Worldwide Plan to Eliminate Global Warming, Air Pollution, and Energy Instability With Wind, Water, and Sunlight (WWS)

    NASA Astrophysics Data System (ADS)

    Jacobson, M. Z.; Delucchi, M. A.

    2011-12-01

    Global warming, air pollution mortality, and energy insecurity are three of the most significant problems facing the world today. This talk discusses a plan to solve the problems by powering 100% of the world's energy for all purposes, including electricity, transportation, industrial processes, and heating/cooling, with wind, water, and sunlight (WWS) within the next 20-40 years. It reviews and ranks major proposed energy solutions to global warming, air pollution mortality, and energy insecurity while considering other impacts of the proposed solutions, such as on water supply, land use, resource availability, reliability, wildlife, and catastrophic risk. It then evaluates a scenario for powering the world on the energy options determined to be the best while also considering materials, transmission infrastructure, costs, and politics. The study concludes that powering the world with WWS electric power technologies and a conversion from combustion to electricity and electrolytically-produced hydrogen is the cleanest and safest method of solving these problems. Due to the efficiency of electricity, such a conversion reduces world power demand by 30%. Methods of ensuring reliability of WWS electric power are available and will be demonstrated. We also conclude that neither liquid biofuels for transportation (including ethanol or biodiesel from any source), solid biofuels for home heating and cooking, biomass for electricity, conventional or fracked natural gas for electricity or transportation, nuclear power, nor coal with carbon capture (clean coal) are nearly so clean or safe as WWS technologies so are not recommended, either as bridge technologies or in the long term. Our plan calls for all new energy to be supplied by WWS-electricity-hydrogen resources no later than 2030 and all existing non-WWS infrastructure to be eliminated no later than 2050. We find that the plan is technically and economically feasible but politically challenging.

    Techniques for air pollution source identification are reviewed, and some results obtained with them are evaluated. Described techniques include remote sensing from satellites and aircraft, on-site monitoring, and the use of injected tracers and pollutants themselves as tracers. The use of a large number of trace elements in ambient airborne particulate matter as a practical means of identifying sources is discussed in detail. Sampling and analysis techniques are described, and it is shown that elemental constituents can be related to specific source types such as those found in the earth's crust and those associated with specific industries. Source identification sytems are noted which utilize charged particle X-ray fluorescence analysis of original field data.

    This paper presents a discussion and comparison of the Raman method, the resonance and fluorescence backscatter method, long path absorption methods and the differential absorption method for remote air pollution measurement. A comparison of the above remote detection methods shows that the absorption methods offer the most sensitivity at the least required transmitted energy. Topographical absorption provides the advantage of a single ended measurement, and differential absorption offers the additional advantage of a fully depth resolved absorption measurement. Recent experimental results confirming the range and sensitivity of the methods are presented.

  18. Outdoor air pollution and asthma

    Guarnieri, Michael; Balmes, John R.

    2015-01-01

    Traffic and power generation are the main sources of urban air pollution. The idea that outdoor air pollution can cause exacerbations of pre-existing asthma is supported by an evidence base that has been accumulating for several decades, with several studies suggesting a contribution to new-onset asthma as well. In this Series paper, we discuss the effects of particulate matter (PM), gaseous pollutants (ozone, nitrogen dioxide, and sulphur dioxide), and mixed traffic-related air pollution. We focus on clinical studies, both epidemiological and experimental, published in the previous 5 years. From a mechanistic perspective, air pollutants probably cause oxidative injury to the airways, leading to inflammation, remodelling, and increased risk of sensitisation. Although several pollutants have been linked to new-onset asthma, the strength of the evidence is variable. We also discuss clinical implications, policy issues, and research gaps relevant to air pollution and asthma. PMID:24792855

  19. Lawrence Livermore National Laboratory Quality Assurance Project Plan for National Emission Standards for Hazardous Air Pollutants (NESHAPs), Subpart H

    Hall, L.; Biermann, A

    2000-06-27

    As a Department of Energy (DOE) Facility whose operations involve the use of radionuclides, Lawrence Livermore National Laboratory (LLNL) is subject to the requirements of 40 CFR 61, the National Emission Standards for Hazardous Air Pollutants (NESHAPs). Subpart H of this Regulation establishes standards for exposure of the public to radionuclides (other than radon) released from DOE Facilities (Federal Register, 1989). These regulations limit the emission of radionuclides to ambient air from DOE facilities (see Section 2.0). Under the NESHAPs Subpart H Regulation (hereafter referred to as NESHAPs), DOE facilities are also required to establish a quality assurance program for radionuclide emission measurements; specific requirements for preparation of a Quality Assurance Program Plan (QAPP) are given in Appendix B, Method 114 of 40 CFR 61. Throughout this QAPP, the specific Quality Assurance Method elements of 40 CFR 61 Subpart H addressed by a given section are identified. In addition, the US Environmental Protection Agency (US EPA) (US EPA, 1994a) published draft requirements for QAPP's prepared in support of programs that develop environmental data. We have incorporated many of the technical elements specified in that document into this QAPP, specifically those identified as relating to measurement and data acquisition; assessment and oversight; and data validation and usability. This QAPP will be evaluated on an annual basis, and updated as appropriate.

    Lee, Suh-Young; Chang, Yoon-Seok

    2013-01-01

    The prevalence of allergic diseases has been increasing rapidly, especially in developing countries. Various adverse health outcomes such as allergic disease can be attributed to rapidly increasing air pollution levels. Rapid urbanization and increased energy consumption worldwide have exposed the human body to not only increased quantities of ambient air pollution, but also a greater variety of pollutants. Many studies clearly demonstrate that air pollutants potently trigger asthma exacerbation. Evidence that transportation-related pollutants contribute to the development of allergies is also emerging. Moreover, exposure to particulate matter, ozone, and nitrogen dioxide contributes to the increased susceptibility to respiratory infections. This article focuses on the current understanding of the detrimental effects of air pollutants on allergic disease including exacerbation to the development of asthma, allergic rhinitis, and eczema as well as epigenetic regulation.

    ABSTRACT Air pollution is becoming a major health problem that affects millions of people worldwide. In support of this observation, the World Health Organization estimates that every year, 2.4 million people die because of the effects of air pollution on health. Mitigation strategies such as changes in diesel engine technology could result in fewer premature mortalities, as suggested by the US Environmental Protection Agency. This review: (i) discusses the impact of air pollution on respiratory disease; (ii) provides evidence that reducing air pollution may have a positive impact on the prevention of disease; and (iii) demonstrates the impact concerted polices may have on population health when governments take actions to reduce air pollution.

    Chaaban, F.G.

    1998-07-01

    Air quality modeling and simulation is an indispensable tool used in different environmental studies that attempt to estimate air pollution levels caused by existing or planned combustion processes, to evaluate proposed emission reduction technologies, to select sites for new emission sources, and accordingly to establish emission control strategies in different energy conversion sectors. Modeling techniques, based on established mathematical formulation, are widely used for simulating air pollution caused mainly by the transportation and electric power sectors. Geographic information systems, GIS, link spatial information to alphanumeric information thus developing geographically referenced database. GIS systems have already been incorporated successfully into several fields in the energy sector and are proven to be a very efficient and robust tool for relevant analysis. In the environmental studies, GIS can answer many questions related to air pollution such as pollution sources as well as identification of regions in which the concentration may exceed limits set by local and international standards. The work presented in this paper is aimed at integrating GIS into air pollution analysis. The main objective is to estimate, using advanced graphical illustrations, the concentration levels of different types of air effluents emitted from point, line, or area sources. The integrated package is then used to examine the influence of various mitigation strategies on the air pollutants levels, and hence to evaluate the effectiveness of these strategies. The paper is concluded by case studies from the transportation and power sectors.

    The application of field ionization mass spectrometry (FIMS) to the detection of air pollutants was investigated. Current methods are reviewed for measuring contaminants of fixed gases, sulfur compounds, nitrogen oxides, hydrocarbons, and particulates. Two enriching devices: the dimethyl silicone rubber membrane separator, and the selective adsorber of polyethylene foam were studied along with FIMS. It is concluded that the membrane enricher system is not a suitable method for removing air pollutants. However, the FIMS shows promise as a useable system for air pollution detection.

    Sever air pollution in China has in recent years caused intensive public, media and governmental attention. Many questions need to be answered about the air pollution in China, such as how harmful is the air pollution, especially PM2.5? Why suddenly so many reports about sever air pollution, is the air in China getting more polluted? How to design a policy that can control the air pollution most efficiently? After updated the national Ambient Air Quality Standards in 2012 and included PM2.5 as one of the critical air pollutants, in 2013, Chinese central government released for the first time the "Air Pollution Prevention and Control Action Plan". The plan has set goals to reduce annual mean concentration of PM2.5 up to 25% in 2017 in different regions in China. If the ambitious goals were achieved, this could be the most significant air pollution reduction in such a short time that affects so many people in human history. To achieve these goals, however, there are enormous scientific and public policy challenges to deal with. For example: Identify the key components, size fraction of PM that have the largest health effects; and identify the sources of PM that has the most harmful effects on human health and ecosystem. Reduce the uncertainty in health risk assessment. Understand complicate chemical transformation processes in air pollution formation with intensive emissions from industry, power plant, vehicles, agriculture. Interactions between air pollution, PBL, and atmospheric circulation at different scales. The accountability, feasibility, effectiveness, and efficiency of air pollution control policies. Integrate multi-pollutant control and achieve co-benefit with climate and energy policy. Regional coordinated air pollution control. The largest challenge in China for air pollution control remains how to strength the link between science and policy.

    PubMed Central

    Cohen, A J; Pope, C A

    1995-01-01

    Epidemiologic studies over the last 40 years suggest rather consistently that general ambient air pollution, chiefly due to the incomplete combustion of fossil fuels, may be responsible for increased rates of lung cancer. This evidence derives from studies of lung cancer trends, studies of occupational groups, comparisons of urban and rural populations, and case-control and cohort studies using diverse exposure metrics. Recent prospective cohort studies observed 30 to 50% increases in lung cancer rates associated with exposure to respirable particles. While these data reflect the effects of exposures in past decades, and despite some progress in reducing air pollution, large numbers of people in the United States continue to be exposed to pollutant mixtures containing known or suspected carcinogens. It is not known how many people in the United States are exposed to levels of fine respirable particles that have been associated with lung cancer in recent epidemiologic studies. These observations suggest that the most widely cited estimates of the proportional contribution of air pollution to lung cancer occurrence in the United States based largely on the results of animal studies, may be too low. It is important that better epidemiologic research be conducted to allow improved estimates of lung cancer risk from air pollution among the general population. The development and application of new epidemiologic methods, particularly the improved characterization of population-wide exposure to mixtures of air pollutants and the improved design of ecologic studies, could improve our ability to measure accurately the magnitude of excess cancer associated with air pollution.

    The techniques available for source identification are reviewed: remote sensing, injected tracers, and pollutants themselves as tracers. The use of the large number of trace elements in the ambient airborne particulate matter as a practical means of identifying sources is discussed. Trace constituents are determined by sensitive, inexpensive, nondestructive, multielement analytical methods such as instrumental neutron activation and charged particle X-ray fluorescence. The application to a large data set of pairwise correlation, the more advanced pattern recognition-cluster analysis approach with and without training sets, enrichment factors, and pollutant concentration rose displays for each element is described. It is shown that elemental constituents are related to specific source types: earth crustal, automotive, metallurgical, and more specific industries. A field-ready source identification system based on time and wind direction resolved sampling is described.

    National Pollutant Discharge Elimination System (NPDES) general permit applications for industrial storm water discharge were to have been filed by October 1992. The Environmental Protection Agency (EPA) and state agencies are now issuing permits based on these applications. One compliance aspect of the permits is the Storm Water Pollution Prevention Plan (SWP3). The plan must identify the facility's potential sources of storm water pollution and develop and implement best management practices (BMPs) to reduce pollutants in storm water runoff. The objectives of the NPDES storm water program are to eliminate illegal dumping and illicit connections, and to reduce pollutants in industrial storm water discharge. These regulations require industry to develop detailed facility site maps, and describe the types, amounts and locations of potential pollutants. Based on this information, industry can develop and implement best management practices to reduce pollutants in storm water runoff.

    In the last few decades, there has been increased population concern for quality of environment, for it is, after life style, the second risk factor of disease development. Particular problem is that a large majority of serious impairments of health is manifested only after a long latent period, so it is not always possible to establish clear association with environmental factors. It is considered today that around 40% of lethal cases are caused by polluted environment in various ways, while environment is the most important etiologic factor in 5% of disease incidence. Problems arising due to environment pollution are most frequently related to air pollution. The World Resource Institute, Washington, has developed the indicators for evaluation of risk of environment pollution to population health. There is one common indicator both for developed and developing countries--air pollution. EPA recommended new standards for some polluting substances. The document reviewed these standards and their implementation in our community. New Law on Environment Protection ("Official Gazette of RS" No. 135/2004) from December 20th, 2004, followed by relevant documents on air quality, should be beneficial to experts at the level of subtle diagnostics and proposal of adequate measures with a view to improve the quality of life.

  13. Contemporary threats and air pollution

    NASA Astrophysics Data System (ADS)

    Hopke, Philip K.

    It is now well understood that air pollution produces significant adverse health effects in the general public and over the past 60 years, there have been on-going efforts to reduce the emitted pollutants and their resulting health effects. There are now shifting patterns of industrialization with many heavily polluting industries moving from developed countries with increasingly stringent air quality standards to the developing world. However, even in decreasing concentrations of pollutants, health effects remain important possibly as a result of changes in the nature of the pollutants as new chemicals are produced and as other causes of mortality and morbidity are reduced. In addition, there is now the potential for deliberate introduction of toxic air pollutants by local armed conflicts and terrorists. Thus, there are new challenges to understand the role of the atmospheric environment on public health in this time of changing economic and demographic conditions overlaid with the willingness to indirectly attack governments and other established entities through direct attacks on the general public.

    The publication of this volume could hardly have been more timely, for concern about the damage to plants from air pollution has grown rapidly in the last few years. The book comprises eighteen chapters by contributors of high repute. Three early chapters deal with Dispersion and Fate of Atmospheric Pollutants, Long Range Transport and Monitoring Levels and Effects of Air Pollutants. They provide essential reading for those working on effects in the field, and they set the scene for a contribution from the Volume Editor on the problems of diagnosis. The central chapters (7 to 11) provide, in considerable depth, a summary of the knowledge of the mechanism of action of pollutants on plants, in terms of physiology, biochemistry, and ultrastructure. Particularly valuable is the essay entitled Impact of Air Pollutant Combinations on Plants, which concludes that even though few generalizations are possible, there is now sufficient evidence to suggest that interactions between some pollutants (e.g. SO/sub 2/ and O/sub 3/, SO/sub 2/ and NO/sub 2/) may seriously damage some plants.

    A new smartphone application takes advantage of various technological capabilities and sensors to help users monitor air quality. Tapping into smartphone cameras, Global Positioning System (GPS) sensors, compasses, and accelerometers, computer scientists with the University of Southern California's (USC) Viterbi School of Engineering have developed a new application, provisionally entitled “Visibility.” Currently available for the Android telephone operating system, the application is available for free download at http://robotics.usc.edu/˜mobilesensing/Projects/AirVisibilityMonitoring. An iPhone application may be introduced soon. Smartphone users can take a picture of the sky and then compare it with models of sky luminance to estimate visibility. While conventional air pollution monitors are costly and thinly deployed in some areas, the smartphone application potentially could help fill in some blanks in existing air pollution maps, according to USC computer science professor Gaurav Sukhatme.

    Pisum sativum L. cv Alsweet (garden pea) and Lycopersicon esculentum flacca Mill. (tomato) were used to evaluate the phytotoxicity of SO2 and O3 in the light and dark. Plants were grown in controlled environment chambers and exposed to SO2 or O3 in the light or dark at the same environmental conditions at which they were grown. The pea plants were treated with fusicoccin to ensure open stomata in the dark; the stomata of the tomato mutant remained open in the dark. Both species exhibited 64% to 80% less foliar necrosis following exposure to SO2 (0.5 to 1.0 microliter per liter for 2 hours) in the light than in the dark. The decrease in SO2 injury for light versus dark exposed plants was greater in fully expanded than expanding leaves. Both species exhibited 30% greater foliar necrosis following exposure to O3 (0.2 microliter per liter for 2 hours) in the light than dark. The increase in O3 injury in the light versus dark was similar for leaves at all stages of expansion. Leaf conductance to water vapor was 7% to 11% and 23% higher in the light than dark for fusicoccin-treated peas and tomato plants, respectively, indicating greater foliar uptake of both pollutants in the light than dark. Thus, the decreased SO2 toxicity in the light was not associated with pollutant uptake, but rather the metabolism of SO2. In contrast, the increased toxicity of O3 in the light was at least in part associated with increased uptake or could not be separated from it. PMID:16663549

  5. Air pollution and cardiovascular disease.

    PubMed

    Franklin, Barry A; Brook, Robert; Arden Pope, C

    2015-05-01

    An escalating body of epidemiologic and clinical research provides compelling evidence that exposure to fine particulate matter air pollution contributes to the development of cardiovascular disease and the triggering of acute cardiac events. There are 3 potential mediating pathways that have been implicated, including "systemic spillover," autonomic imbalance, and circulating particulate matter constituents. Further support that the increased morbidity and mortality attributed to air pollution comes from studies demonstrating the adverse cardiovascular effects of even brief periods of exposure to secondhand smoke. Accordingly, persons with known or suspected cardiovascular disease, the elderly, diabetic patients, pregnant women, and those with pulmonary disease should be counseled to limit leisure-time outdoor activities when air pollution is high. Recognizing the insidious and pervasive nature of air pollution, and the associated odds ratios and population attributable fractions for this widely underappreciated chemical trigger of acute cardiovascular events, may serve to maximize the potential for cardiovascular risk reduction by addressing at least a portion of the 10%-25% incidence of coronary disease that is unexplained by traditional risk factors.

  11. Review of air pollution and health impacts in Malaysia.

    Afroz, Rafia; Hassan, Mohd Nasir; Ibrahim, Noor Akma

    2003-06-01

    In the early days of abundant resources and minimal development pressures, little attention was paid to growing environmental concerns in Malaysia. The haze episodes in Southeast Asia in 1983, 1984, 1991, 1994, and 1997 imposed threats to the environmental management of Malaysia and increased awareness of the environment. As a consequence, the government established Malaysian Air Quality Guidelines, the Air Pollution Index, and the Haze Action Plan to improve air quality. Air quality monitoring is part of the initial strategy in the pollution prevention program in Malaysia. Review of air pollution in Malaysia is based on the reports of the air quality monitoring in several large cities in Malaysia, which cover air pollutants such as Carbon monoxide (CO), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), and Suspended Particulate Matter (SPM). The results of the monitoring indicate that Suspended Particulate Matter (SPM) and Nitrogen Dioxide (NO2) are the predominant pollutants. Other pollutants such as CO, O(x), SO2, and Pb are also observed in several big cities in Malaysia. The air pollution comes mainly from land transportation, industrial emissions, and open burning sources. Among them, land transportation contributes the most to air pollution. This paper reviews the results of the ambient air quality monitoring and studies related to air pollution and health impacts. PMID:12854685

    2012-12-01

    During the SHIVA (Stratospheric Ozone: Halogen Impacts in a Varying Atmosphere) campaign in Nov. and Dec. 2011 a number of polluted air masses were observed in the marine and terrestrial boundary layer (0 - 2 km) and in the free troposphere (2 - 12 km) over Borneo/Malaysia. The measurements include isoprene, CO, CO2, CH4, N2O, NO2, SO2 as primary pollutants, O3 and HCHO as secondary pollutants, and meteorological parameters. This set of trace gases can be used to fingerprint different sources of local and regional air pollution (e.g., biomass burning and fossil fuel burning, gas flaring on oil rigs, emission of ships and from urban areas, volcanic emissions, and biogenic emissions). Individual sources and location can be identified when the measurements are combined with a nested-grid regional scale chemical and meteorological model and lagrangian particle dispersion model (e.g., CCATT-BRAMS and FLEXPART). In the case of the former, emission inventories of the primary pollutants provide the basis for the trace gas simulations. In this region, the anthropogenic influence on air pollution seems to dominate over natural causes. For example, CO2 and CH4 often show strong correlations with CO, suggesting biomass burning or urban fossil fuel combustion dominates the combustion sources. The study of the CO/CO2 and CH4/CO ratios can help separate anthropogenic combustion from biomass burning pollution sources. In addition, these ratios can be used as a measure of combustion efficiency to help place the type of biomass burning particular to this region within the wider context of fire types found globally. On several occasions, CH4 enhancements are observed near the ocean surface, which are not directly correlated with CO enhancements thus indicating a non-combustion-related CH4 source. Positive correlations between SO2 and CO show the anthropogenic influence of oil rigs located in the South China Sea. Furthermore, SO2 enhancements are observed without any increase in CO

    A study is presented on the remote sensing of gaseous and particulate air pollutants which is an extension of a previous report. Pollutants can be observed by either active or passive remote sensing systems. Calculations discussed herein indicate that tropospheric CO, CO2, SO2, NO2, NH3, HCHO, and CH4 can be measured by means of nadir looking passive systems. Additional species such as NO, HNO3, O3, and H2O may be measured in the stratosphere through a horizon experiment. A brief theoretical overview of resonance Raman scattering and resonance fluorescence is given. It is found that radiance measurements are most promising for general global applications, and that stratospheric aerosols may be measured using a sun occultation technique. The instrumentation requirements for both active and passive systems are examined and various instruments now under development are described.

  13. The health effects of exercising in air pollution.

    PubMed

    Giles, Luisa V; Koehle, Michael S

    2014-02-01

    The health benefits of exercise are well known. Many of the most accessible forms of exercise, such as walking, cycling, and running often occur outdoors. This means that exercising outdoors may increase exposure to urban air pollution. Regular exercise plays a key role in improving some of the physiologic mechanisms and health outcomes that air pollution exposure may exacerbate. This problem presents an interesting challenge of balancing the beneficial effects of exercise along with the detrimental effects of air pollution upon health. This article summarizes the pulmonary, cardiovascular, cognitive, and systemic health effects of exposure to particulate matter, ozone, and carbon monoxide during exercise. It also summarizes how air pollution exposure affects maximal oxygen consumption and exercise performance. This article highlights ways in which exercisers could mitigate the adverse health effects of air pollution exposure during exercise and draws attention to the potential importance of land use planning in selecting exercise facilities.

  15. The Particulate Air Pollution Controversy

    PubMed Central

    Phalen, Robert F.

    2004-01-01

    Scientists, regulators, legislators, and segments of industry and the lay public are attempting to understand and respond to epidemiology findings of associations between measures of modern particulate air pollutants (PM) and adverse health outcomes in urban dwellers. The associations have been interpreted to imply that tens of thousands of Americans are killed annually by small daily increments in PM. These epidemiology studies and their interpretations have been challenged, although it is accepted that high concentrations of air pollutants have claimed many lives in the past. Although reproducible and statistically significant, the relative risks associated with modern PM are very small and confounded by many factors. Neither toxicology studies nor human clinical investigations have identified the components and/or characteristics of PM that might be causing the health-effect associations. Currently, a massive worldwide research effort is under way in an attempt to identify whom might be harmed and by what substances and mechanisms. Finding the answers is important, because control measures have the potential not only to be costly but also to limit the availability of goods and services that are important to public health.

    Air pollution, especially haze pollution, is creating health issues for both humans and other animals. However, remarkably little is known about how animals behaviourally respond to air pollution. We used multiple linear regression to analyse 415 pigeon races in the North China Plain, an area with considerable air pollution, and found that while the proportion of pigeons successfully homed was not influenced by air pollution, pigeons homed faster when the air was especially polluted. Our results may be explained by an enhanced homing motivation and possibly an enriched olfactory environment that facilitates homing. Our study provides a unique example of animals' response to haze pollution; future studies are needed to identify proposed mechanisms underlying this effect. PMID:26728113

  2. Hazardous air pollutants and asthma.

    PubMed Central

    Leikauf, George D

    2002-01-01

    Asthma has a high prevalence in the United States, and persons with asthma may be at added risk from the adverse effects of hazardous air pollutants (HAPs). Complex mixtures (fine particulate matter and tobacco smoke) have been associated with respiratory symptoms and hospital admissions for asthma. The toxic ingredients of these mixtures are HAPs, but whether ambient HAP exposures can induce asthma remains unclear. Certain HAPs are occupational asthmagens, whereas others may act as adjuncts during sensitization. HAPs may exacerbate asthma because, once sensitized, individuals can respond to remarkably low concentrations, and irritants lower the bronchoconstrictive threshold to respiratory antigens. Adverse responses after ambient exposures to complex mixtures often occur at concentrations below those producing effects in controlled human exposures to a single compound. In addition, certain HAPs that have been associated with asthma in occupational settings may interact with criteria pollutants in ambient air to exacerbate asthma. Based on these observations and past experience with 188 HAPs, a list of 19 compounds that could have the highest impact on the induction or exacerbation of asthma was developed. Nine additional compounds were identified that might exacerbate asthma based on their irritancy, respirability, or ability to react with biological macromolecules. Although the ambient levels of these 28 compounds are largely unknown, estimated exposures from emissions inventories and limited air monitoring suggest that aldehydes (especially acrolein and formaldehyde) and metals (especially nickel and chromium compounds) may have possible health risk indices sufficient for additional attention. Recommendations for research are presented regarding exposure monitoring and evaluation of biologic mechanisms controlling how these substances induce and exacerbate asthma. PMID:12194881

    Despite the large ratio of land mass to population, Canada has significant air pollution problems, some being due to our cold climate, the long arctic nights, and a mineral-based economy. Routes of intoxication include the respiration of polluted air and the secondary contamination of food and water. Although pollution is often measured in terms of industrial emissions, the physician must be concerned rather with the dose of pollutants to which the individual is exposed. The principal air pollutants, in terms of emitted tonnage, are carbon monoxide, sulfur dioxide, hydrocarbons, particulates, and oxides of nitrogen. Sources of these various materials are discussed.

  4. Hybrid regional air pollution models

    SciTech Connect

    1980-03-01

    This discussion deals with a family of air quality models for predicting and analyzing the fine particulate loading in the atmosphere, for assessing the extent and degree of visibility impairment, and for determining the potential of pollutants for increasing the acidity of soils and water. The major horizontal scales of interest are from 400km to 2000km; and the time scales may vary from several hours, to days, weeks, and a few months or years, depending on the EPA regulations being addressed. First the role air quality models play in the general family of atmospheric simulation models is described. Then, the characteristics of a well-designed, comprehensive air quality model are discussed. Following this, the specific objectives of this workshop are outlined, and their modeling implications are summarized. There are significant modeling differences produced by the choice of the coordinate system, whether it be the fixed Eulerian system, the moving Lagrangian system, or some hybrid of the two. These three systems are briefly discussed, and a list of hybrid models that are currently in use are given. Finally, the PNL regional transport model is outlined and a number of research needs are listed.
