  3. Airing 'clean air' in Clean India Mission.

    PubMed

    Banerjee, T; Kumar, M; Mall, R K; Singh, R S

    2016-12-30

    The submission explores the possibility of a policy revision for considering clean air quality in recently launched nationwide campaign, Clean India Mission (CIM). Despite of several efforts for improving availability of clean household energy and sanitation facilities, situation remain still depressing as almost half of global population lacks access to clean energy and proper sanitation. Globally, at least 2.5 billion people do not have access to basic sanitation facilities. There are also evidences of 7 million premature deaths by air pollution in year 2012. The situation is even more disastrous for India especially in rural areas. Although, India has reasonably progressed in developing sanitary facilities and disseminating clean fuel to its urban households, the situation in rural areas is still miserable and needs to be reviewed. Several policy interventions and campaigns were made to improve the scenario but outcomes were remarkably poor. Indian census revealed a mere 31% sanitation coverage (in 2011) compared to 22% in 2001 while 60% of population (700 million) still use solid biofuels and traditional cook stoves for household cooking. Further, last decade (2001-2011) witnessed the progress decelerating down with rural households without sanitation facilities increased by 8.3 million while minimum progress has been made in conversion of conventional to modern fuels. To revamp the sanitation coverage, an overambitious nationwide campaign CIM was initiated in 2014 and present submission explores the possibility of including 'clean air' considerations within it. The article draws evidence from literatures on scenarios of rural sanitation, energy practises, pollution induced mortality and climatic impacts of air pollution. This subsequently hypothesised with possible modification in available technologies, dissemination modes, financing and implementation for integration of CIM with 'clean air' so that access to both sanitation and clean household energy may be

  7. Air Cleaning Technologies

    PubMed Central

    2005-01-01

    Executive Summary Objective This health technology policy assessment will answer the following questions: When should in-room air cleaners be used? How effective are in-room air cleaners? Are in-room air cleaners that use combined HEPA and UVGI air cleaning technology more effective than those that use HEPA filtration alone? What is the Plasmacluster ion air purifier in the pandemic influenza preparation plan? The experience of severe acute respiratory syndrome (SARS) locally, nationally, and internationally underscored the importance of administrative, environmental, and personal protective infection control measures in health care facilities. In the aftermath of the SARS crisis, there was a need for a clearer understanding of Ontario’s capacity to manage suspected or confirmed cases of airborne infectious diseases. In so doing, the Walker Commission thought that more attention should be paid to the potential use of new technologies such as in-room air cleaning units. It recommended that the Medical Advisory Secretariat of the Ontario Ministry of Health and Long-Term Care evaluate the appropriate use and effectiveness of such new technologies. Accordingly, the Ontario Health Technology Advisory Committee asked the Medical Advisory Secretariat to review the literature on the effectiveness and utility of in-room air cleaners that use high-efficiency particle air (HEPA) filters and ultraviolet germicidal irradiation (UVGI) air cleaning technology. Additionally, the Ontario Health Technology Advisory Committee prioritized a request from the ministry’s Emergency Management Unit to investigate the possible role of the Plasmacluster ion air purifier manufactured by Sharp Electronics Corporation, in the pandemic influenza preparation plan. Clinical Need Airborne transmission of infectious diseases depends in part on the concentration of breathable infectious pathogens (germs) in room air. Infection control is achieved by a combination of administrative, engineering

    VanOsdell, D.W.; Sparks, L.E.

    1995-02-01

    Gas-phase air filtration equipment (GPAFE) has been applied for many years to control industrial gaseous contaminants. Interest in cleaning recirculation air to provide ventilation without the need to condition excessive outdoor air has promoted increased interest in GPAFE as indoor air control devices. The removal of volatile organic compounds (VOCs) using granular activated carbon (GAC) is the focus of this article. First, the authors present performance measurements for GAC at low challenge VOC concentrations that might be encountered indoors. Unlike previously reported tests, these were continued long enough to directly determine the GAC`s expected lifetime. The results suggest that test results obtained at high challenge concentrations may be extrapolated to low, indoor concentrations. Further study is needed, but these data are encouraging. Second, they will discuss the implications of these performance measurements for the use of GAC to remove VOCs and improve indoor air quality (IAQ) using an indoor air building simulation model.

  11. Cleaning and Sterilisation of Anaesthetic Equipment

    PubMed Central

    Juwarkar, Chitra Sanjeev

    2013-01-01

    The main purpose of this review article is to bring up what has been known (practiced) about decontamination, disinfection, and sterilisation of anaesthetic equipment. It also discusses how this evidence-based information on infection prevention and control impacts care of patient in routine anaesthesia practice. This review underscores the role played by us, anaesthetists in formulating guidelines, implementing the same, monitoring the outcome and training post-graduate trainees and coworkers in this regard. The article re-emphasises that certain guidelines when followed strictly will go a long way in reducing transmission of hospital acquired infection between patient and anaesthetist or between patients. Anaesthetists do not restrict their work to operating room but are involved in disaster management, interventional radiological procedures and in trauma care. They should ensure that the patients are cared for in clean and safe environment so as to reduce healthcare associated infections (HCAIs) simultaneously taking preventive measures against the various health hazards associated with clinical practice. They should ensure that the coworkers too adopt all the preventive measures while delivering their duties. For this review, we conducted literature searches in Medline (PubMed) and also searched for relevant abstracts and full texts of related articles that we came across. There is much to be learned from the western world where, health care organisations now have legal responsibility to implement changes in accordance with the newer technology to reduce health care associated infection. There is a need to develop evidence-based infection prevention and control programs and set national guidelines for disinfection and sterilisation of anaesthesia equipment which all the institutions should comply with.

  15. Cleanliness audit of clinical surfaces and equipment: who cleans what?

    PubMed

    Anderson, R E; Young, V; Stewart, M; Robertson, C; Dancer, S J

    2011-07-01

    Current guidelines recommend regular cleaning of clinical equipment. We monitored items on a surgical ward for predominant user, hand-touch frequency, cleaning responsibilities and measurement of organic soil. Equipment was assessed in triplicate against a cleanliness benchmark of 100 relative light units (RLU) using the Hygiena® ATP system. There were 44 items, of which 21 were cleaned by clinical support workers (CSWs), five by domestic staff; three by nurses, three by doctors, and 12 with no designated cleaning responsibility. Geometric mean RLUs ranged from 60 to 550/100 cm² for small items such as hand-gel containers, bed control, blood pressure cuff and clinical notes; with similar values of 80-540/100 cm² RLU for larger items such as electrocardiogram machine, defibrillator, trolleys and tables. Overall geometric mean was 249/100 cm² RLU for all surfaces, with 84% (37 of 44) items exceeding the 100RLU benchmark. Of 27 items cleaned by clinical staff, 24 (89%) failed the benchmark. Of 12 sites with no cleaning specification, 11 (92%) failed the benchmark. Three of seven 'clean' sites (<100/100 cm² RLU) were cleaned by domestic staff. Average log(10) RLU of surfaces cleaned by domestics were 64% lower compared with surfaces cleaned by CSWs (95% confidence interval: 35%, 80%; P=0.019). In conclusion, clinical equipment frequently demonstrates high levels of organic soil, whether or not items have assigned cleaning responsibility. These findings suggest that cleaning practices for clinical equipment may require review, along with education of staff with specific cleaning responsibilities.

  16. The Value of Clean Air

    NASA Astrophysics Data System (ADS)

    Shindell, D. T.

    2014-12-01

    How can society place a value on clean air? I present a multi-impact economic valuation framework called the Social Cost of Atmospheric Release (SCAR) that extends the Social Cost of Carbon (SCC) used previously for carbon dioxide (CO2) to a broader range of pollutants and impacts. Values consistently incorporate health impacts of air quality along with climate damages. The latter include damages associated with aerosol-induced hydrologic cycle changes that lead to net climate benefits when reducing cooling aerosols. Evaluating a 1% reduction in current global emissions, benefits with a high discount rate are greatest for reductions of co-emitted products of incomplete combustion (PIC), followed by sulfur dioxide (SO2), nitrogen oxides (NOx) and then CO2, ammonia and methane. With a low discount rate, benefits are greatest for CO2 reductions, though the sum of SO2, PIC and methane is substantially larger. These results suggest that efforts to mitigate atmosphere-related environmental damages should target a broad set of emissions including CO2, methane and aerosol/ozone precursors. Illustrative calculations indicate environmental damages are 410-1100 billion yr-1 for current US electricity generation ( 19-46¢ per kWh for coal, 4-24¢ for gas) and 3.80 (-1.80/+2.10) per gallon of gasoline ($4.80 (-3.10/+3.50) per gallon for diesel). These results suggest that total atmosphere-related environmental damages plus generation costs are much greater for coal-fired power than other types of electricity generation, and that damages associated with gasoline vehicles substantially exceed those for electric vehicles.

  17. Air contaminants in a submarine equipped with air independent propulsion.

    PubMed

    Persson, Ola; Ostberg, Christina; Pagels, Joakim; Sebastian, Aleksandra

    2006-11-01

    The Swedish Navy has operated submarines equipped with air independent propulsion for two decades. This type of submarine can stay submerged for periods far longer than other non-nuclear submarines are capable of. The air quality during longer periods of submersion has so far not been thoroughly investigated. This study presents results for a number of air quality parameters obtained during more than one week of continuous submerged operation. The measured parameters are pressure, temperature, relative humidity, oxygen, carbon dioxide, hydrogen, formaldehyde and other volatile organic compounds, ozone, nitrogen dioxide, particulate matter and microbiological contaminants. The measurements of airborne particles demonstrate that air pollutants typically occur at a low baseline level due to high air exchange rates and efficient air-cleaning devices. However, short-lived peaks with comparatively high concentrations occur, several of the sources for these have been identified. The concentrations of the pollutants measured in this study do not indicate a build-up of hazardous compounds during eight days of submersion. It is reasonable to assume that a substantial build-up of the investigated contaminants is not likely if the submersion period is prolonged several times, which is the case for modern submarines equipped with air independent propulsion.

    SciTech Connect

    Glissmeyer, J.A.; Mishima, J.; Bamberger, J.A.

    1985-01-01

    This report recommends air cleaning system components for the US Army Ballistics Research Laboratory's new large-caliber firing range, which is used for testing depleted uranium (DU) penetrators. The new air cleaning system has lower operating costs during the life of the system compared to that anticipated for the existing air cleaning system. The existing system consists of three banks of filters in series; the first two banks are prefilters and the last are high-efficiency particulate air (HEPA) filters. The principal disadvantage of the existing filters is that they are not cleanable and reusable. Pacific Northwest Laboratory focused the search for alternate air cleaning equipment on devices that do not employ liquids as part of the particle collection mechanism. Collected dry particles were assumed preferable to a liquid waste stream. The dry particle collection devices identified included electrostatic precipitators; inertial separators using turning vanes or cyclones; and several devices employing a filter medium such as baghouses, cartridge houses, cleanable filters, and noncleanable filters similar to those in the existing system. The economics of practical air cleaning systems employing the dry particle collection devices were evaluated in 294 different combinations. 7 references, 21 figures, 78 tables.

  9. Clean Air Slots Amid Atmospheric Pollution

    NASA Technical Reports Server (NTRS)

    Hobbs, Peter V.

    2002-01-01

    Layering in the Earth's atmosphere is most commonly seen where parts of the atmosphere resist the incursion of air parcels from above and below - for example, when there is an increase in temperature with height over a particular altitude range. Pollutants tend to accumulate underneath the resulting stable layers. which is why visibility often increases markedly above certain altitudes. Here we describe the occurrence of an opposite effect, in which stable layers generate a layer of remarkably clean air (we refer to these layers as clean-air 'slots') sandwiched between layers of polluted air. We have observed clean-air slots in various locations around the world, but they are particularly well defined and prevalent in southern Africa during the dry season August-September). This is because at this time in this region, stable layers are common and pollution from biomass burning is widespread.

    We evaluated air cleaning as a means to mitigate risks arising from exposure to indoor radon progeny in several single-family houses in the northeastern United States, using a new, automated, semi-continuous activity-weighted size distribution measurement system. Measurements included radon concentration, condensation nuclei count, and activity-weighted size distribution of radon decay products. Measurements were made with and without the air cleaning system operating. The influence of particles generated by various sources common to normal indoor activities on radon progeny behavior was evaluated. Aerosols were generated by running water in a shower, burning candles, smoking cigarettes, vacuuming, opening doors, and cooking. Both a filtration unit and an electrostatic precipitator were evaluated. Using a room model, the changes in attachment rates, average attachment diameters, and deposition rates of the ``unattached`` fraction with and without the air cleaning systems were calculated. The air cleaner typically reduced the radon progeny concentrations by 50 to 60%.

    Major conclusions and recommendations of the National Commission on Air Quality on issues of health in the Clean Air Act are presented. The issues revolve mainly about the standard setting processes for ubiquitous pollutants, controlled through ambient air quality standards (Section 109), and for hazardous pollutants controlled through emission standards (Section 112). The conceptual difficulties inherent in the terms "adequate margin of safety" (Section 109) and "ample margin of safety" (Section 112) are discussed. The Clean Air Science Advisory Committee is widely viewed as having a salutary effect on standard setting. The need for maintaining strong research capabilities within the Environmental Protection Agency that are reasonably buffered against sudden disruptive events is emphasized. Mechanisms for achieving this goal through special congressional appropriations are considered. PMID:6653527

    Clean indoor air policies are an effective way to eliminate exposure to second hand smoke and reduce smoking among youth and adults; they are strongly recommended by the Surgeon General and the Task Force on Community Preventive Services. How these policies are put into effect and at what level of government can make a difference. Legislation that preempts local action prevents communities from enacting more stringent laws or tailoring laws to address community-specific issues. Preemptive state laws also can be a barrier to local enforcement because communities not involved in decision making may be less aware of laws, may have no enforcement mechanism, and thus may be less complaint. Preemption is clearly a tobacco industry strategy to take away local control, usually in exchange for a weak law offering little protection from second hand smoke. As communities across the country continue to pass stronger local ordinances, eliminating preemptive laws becomes more important. During 2002, Delaware became the first state to repeal clean air preemption. In Iowa, the attorney general's office has been involved in the determination of whether the state clean air law prevents communities from passing more stringent ordinances. And although Minnesota's pioneer Clean Indoor Air Act does not preempt local laws, the debate over preemption there has not ended but instead has taken new forms.

    The Clean Air Power Initiative (CAPI) is a multi-stakeholder project intended to improve air pollution control efforts involving the power generating industry. This paper documents the progress made in the first year of the initiative, which included a number of meetings with interested stakeholders and development and analysis of alternative approaches for more efficient and effective pollution control. The project`s goal is to develop an integrated regulatory strategy or three major pollutants emitted from electric power generators; namely, sulfur dioxide, nitrogen oxides, and, potentially, mercury. Major reductions in these pollutants are expected to be needed to reduce the detrimental health effects of ground-level ozone, fine particles, and hazardous air pollutants and reduce the environmental effects of acidification, eutrophication, ecosystem, crop, and materials damage, and regional haze. The Clean Air Power Initiative has considered, where feasible, new approaches to pollution control that recognize the long-range transport of many air pollutants and the economic benefits of emissions trading. The project was initiated by EPA`s Assistant Administrator for Air and Radiation in 1995. As individual companies develop and implement strategies to participate in more competitive power markets, they could benefit from greater certainty in being able to plan for and reduce costs of future environmental regulations. The EPA is interested in reinventing its regulatory approach to reduce the number, administrative complexity, and cost of its requirements while improving the likelihood of achieving environmental results.

  13. Proposed Clean Air Act reform draws fire

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

    A Congressional hearing on the accomplishments of the U.S. Clean Air Act and subsequent amendments turned into a squabble about whether Bush administration efforts to reform the act would improve or undermine air quality regulations.At the 1 May hearing of the House of Representatives' Subcommittee on Energy and Air Quality, a key sticking point concerned whether an emissions "cap-and-trade" program, which was proposed as part of President George W. Bush's 14 February Clear Skies initiative, would effectively meet air quality standards. The program would provide market-based incentives to reduce emissions of sulfur dioxide, nitrogen oxides, and mercury. Another point of contention was whether such a program would make some current regulations, including new source review of upgraded utility plants, redundant and unnecessary.

  14. Examining antecedents of clean indoor air policy support: implications for campaigns promoting clean indoor air.

    This investigation sought to examine the association between knowledge of the risks associated with environmental tobacco smoke and voter support for clean indoor air policies. In doing so, 2 antecedents were employed to enhance understanding of this relationship: attitudes and subjective norms. In addition, differences between nonsmokers and smokers were assessed across the aforementioned variables. The study sampled participants (N = 550) living in the Appalachian foothills as a means of conducting formative research prior to developing messages promoting clean indoor air policies. The study controlled for tobacco usage, age, biological sex, and income. Results revealed that awareness of risk is a good predictor of attitudes and social norms, and in return, attitudes and social norms are good predictors of support for clean indoor air policies. In addition, results reveal that nonsmokers maintain a significantly stronger belief in the dangers associated with environmental tobacco smoke, as well as more favorable attitudes, subjective norms, and support for clean indoor air policies when compared with smokers. These findings are discussed with a focus on message design strategies for practitioners and academics with interests in promoting clean indoor air policies.

    Guide explains the different types of alternative fuel commercial mowers and lists the makes and models of the ones available on the market. Turf grass is a fixture of the American landscape and the American economy. It is the nation's largest irrigated crop, covering more than 40 million acres. Legions of lawnmowers care for this expanse during the growing season-up to year-round in the warmest climates. The annual economic impact of the U.S. turf grass industry has been estimated at more than $62 billion. Lawn mowing also contributes to the nation's petroleum consumption and pollutant emissions. Mowers consume 1.2 billion gallons of gasoline annually, about 1% of U.S. motor gasoline consumption. Commercial mowing accounts for about 35% of this total and is the highest-intensity use. Large property owners and mowing companies cut lawns, sports fields, golf courses, parks, roadsides, and other grassy areas for 7 hours per day and consume 900 to 2,000 gallons of fuel annually depending on climate and length of the growing season. In addition to gasoline, commercial mowing consumes more than 100 million gallons of diesel annually. Alternative fuel mowers are one way to reduce the energy and environmental impacts of commercial lawn mowing. They can reduce petroleum use and emissions compared with gasoline- and diesel-fueled mowers. They may also save on fuel and maintenance costs, extend mower life, reduce fuel spillage and fuel theft, and promote a 'green' image. And on ozone alert days, alternative fuel mowers may not be subject to the operational restrictions that gasoline mowers must abide by. To help inform the commercial mowing industry about product options and potential benefits, Clean Cities produced this guide to alternative fuel commercial lawn equipment. Although the guide's focus is on original equipment manufacturer (OEM) mowers, some mowers can be converted to run on alternative fuels. For more information about propane conversions.

  10. Identification of Candidate Clean Air Corridors for the Colorado Plateau.

    PubMed

    Gratn, M C; Pitchford, M L; Ashbaugh, L

    1996-05-01

    The U.S. Clean Air Act, amended in 1990, mandated the establishment of the Grand Canyon Visibility Transport Commission (GCVTC). The commission is required to submit a report to the U.S. Environmental Protection Agency addressing visibility issues in the region, including "the establishment of clean air corridors, in which additional restrictions on increases in emissions may be appropriate to protect visibility in affected Class I areas." This paper presents a methodology to identify candidate geographic areas for consideration for Clean Air Corridor (CAC) status for Colorado Plateau Class I areas. The methodology uses thousands of model determined trajectories over a five year period (1988 to 1992) to indicate the paths taken by air that arrives during clean air conditions at Class I areas. These clean air back-trajectories identify upwind areas where pollution emissions could jeopardize currently pristine visibility. Using this methodology, six candidate areas are identified, ranging in size from 75,000 to 506,000 square miles, and permitting varying levels of visibility protection for clean air days at Grand Canyon, Canyonlands, and Petrified Forest National Parks. Assuming effective emissions management of the CAC, the larger the CAC, the greater the visibility protection during clean air conditions.

  11. Air cleaning issues with contaminated sites

    SciTech Connect

    Bellamy, R.R.

    1997-08-01

    The US Nuclear Regulatory Commission has developed a list of contaminated sites that warrant special USNRC attention because they pose unique or complex decommissioning issues. This list of radiologically contaminated sites is termed the Site Decommissioning Management Plan (SDMP), and was first issued in 1990. A site is placed on the SDMP list if it has; (1) Problems with the viability of the responsible organization (e.g., the licensee for the site is unable or unwilling to pay for the decommissioning); (2) Large amounts of soil contamination or unused settling ponds or burial grounds that may make the waste difficult to dispose of; (3) The long-term presence of contaminated, unused buildings; (4) A previously terminated license; or (5) Contaminated or potential contamination of the ground water from on-site wastes. In deciding whether to add a site to the SDMP list, the NRC also considers the projected length of time for decommissioning and the willingness of the responsible organization to complete the decommissioning in a timely manner. Since the list was established, 9 sites have been removed from the list, and the current SDMP list contains 47 sites in 11 states. The USNRC annually publishes NUREG-1444, {open_quotes}Site Decommissioning Management Plan{close_quotes}, which updates the status of each site. This paper will discuss the philosophical goals of the SDMP, then will concentrate on the regulatory requirements associated with air cleaning issues at the SDMP sites during characterization and remediation. Both effluent and worker protection issues will be discussed. For effluents, the source terms at sites will be characterized, and measurement techniques will be presented. Off-site dose impacts will be included. For worker protection issues, air sampling analyses will be presented in order to show how the workers are adequately protected and their doses measured to satisfy regulatory criteria during decontamination operations. 1 tab.

  12. What is an effective portable air cleaning device? A review.

    Shaughnessy, R J; Sextro, R G

    2006-04-01

    The use of portable air cleaning devices in residential settings has been steadily growing over the last 10 years. Three out of every 10 households now contain a portable air cleaning device. This increased use of air cleaners is accompanied by, if not influenced by, a fundamental belief by consumers that the air cleaners are providing an improved indoor air environment. However, there is a wide variation in the performance of air cleaners that is dependent on the specific air cleaner design and various indoor factors. The most widely used method in the United States to assess the performance of new air cleaners is the procedure described in the American National Standards Institute (ANSI)/Association of Home Appliance Manufacturers (AHAM) AC-1-2002. This method describes both the test conditions and the testing protocol. The protocol yields a performance metric that is based on the measured decay rate of contaminant concentrations with the air cleaner operating compared with the measured decay rate with the air cleaner turned off. The resulting metric, the clean air delivery rate (CADR), permits both an intercomparison of performance among various air cleaners and a comparison of air cleaner operation to other contaminant removal processes. In this article, we comment on the testing process, discuss its applicability to various contaminants, and evaluate the resulting performance metrics for effective air cleaning.

There are currently thousands of clean indoor air laws throughout the Unites States, and the majority of Americans live in areas where smoking is completely prohibited in workplaces, restaurants, or bars. The vast majority of scientific evidence indicates that there is no negative economic impact of clean indoor air policies, with many studies finding that there may be some positive effects on local businesses. This is despite the fact that tobacco industry-sponsored research has attempted to create fears to the contrary. Further progress in the diffusion of clean indoor air laws will depend on the continued documentation of the economic impact of clean indoor air laws, particularly within the hospitality industry. This article reviews the spread of clean indoor air laws, the effect on public health, and the scientific evidence of the economic impact of implementation of clean indoor air laws.

    The complicate question's solution of motor winding cleaning need new technologies such as ultrasonic cleaning. The mechanism of problems that the insulation level of the motor winding would be degraded with time and the motor winding would resumed tide soon after processing were analyzed. The ultrasonic cleaning method was studies and one ultrasonic cleaning device was designed. Its safety was verified by the destructive experiment. The test show that this device can clear away the depositional dirt in the winding thoroughly, which provides a new idea and method to ensure its insulation level and realize its safe and reliable operation.

    1992-12-01

    The Clean Air Act amendments of 1990 will intensify national efforts to reduce air pollution. They will have major impacts an governmental agencies and on industrial and commercial facilities throughout the country. As with other industries, it is essential for fertilizer dealers and producers to understand how these changes to the Clean Air Act can significantly change the way they do business. This paper is proffered as an overview of ways in which the 1990 amendments to the Clean Air Act may impact the fertilizer industry. The nonattainment, toxics, and permit provisions of the amended act will be three areas of particular concern to the fertilizer industry. Implementation of the new regulatory requirements of this legislation promises to be a long and onerous process for all concerned. However, it appears that state and local regulations may have a much more profound impact on the fertilizer industry than the new Clean Air Act.

  8. New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy

    SciTech Connect

    Sidheswaran, Meera; Destaillats, Hugo; Sullivan, Douglas P.; Fisk, William J.

    2010-10-27

    Approximately ten percent of the energy consumed in U.S. commercial buildings is used by HVAC systems to condition outdoor ventilation air. Reducing ventilation rates would be a simple and broadly-applicable energy retrofit option, if practical counter measures were available that maintained acceptable concentrations of indoor-generated air pollutants. The two general categories of countermeasures are: 1) indoor pollutant source control, and 2) air cleaning. Although pollutant source control should be used to the degree possible, source control is complicated by the large number and changing nature of indoor pollutant sources. Particle air cleaning is already routinely applied in commercial buildings. Previous calculations indicate that particle filtration consumes only 10percent to 25percent of the energy that would otherwise be required to achieve an equivalent amount of particle removal with ventilation. If cost-effective air cleaning technologies for volatile organic compounds (VOCs) were also available, outdoor air ventilation rates could be reduced substantially and broadly in the commercial building stock to save energy. The research carried out in this project focuses on developing novel VOC air cleaning technologies needed to enable energy-saving reductions in ventilation rates. The minimum required VOC removal efficiency to counteract a 50percent reduction in ventilation rate for air cleaning systems installed in the HVAC supply airstream is modest (generally 20percent or less).

    The Clean Air Act Amendments of 1990 have expanded the requirements for trace metal and air toxics information in urban areas and added new requirements for this information in rural areas and ecosystems. Specific provisions germane to trace metals and other air toxics compounds are found in Title III, Section 112 and in Title IX, Section 901. In response to these provisions, the United States Environmental Protection Agency (EPA) plans to conduct research in atmospheric monitoring networks in urban areas, in the Great Lakes watershed, and in regional components of a national Clean Air Act status and trends network.

  10. The utility of anger in promoting clean indoor air policies.

    2009-09-01

    This investigation examined antecedents associated with support for clean indoor air policies. Participants (N = 550) living in a Midwestern county (population = 62,223) were randomly sampled. Results suggest that beliefs in the health risks associated with secondhand smoke are positively associated with favorable attitudes toward clean indoor air policies, whereas trait reactance is negatively associated with these attitudes. Findings also indicate that risks and trait reactance are indirectly associated with support for clean indoor air policies, mediated through anger arousal toward exposure to secondhand smoke. In addition, regression analyses revealed that health risks, trait reactance, and smoking status explained a significant amount of variance regarding anger toward exposure to secondhand smoke, but only health risks and smoking status accounted for a significant amount of variance toward clean indoor air attitudes. Finally, the Smoking Status x Health Risks interaction was supported for anger toward exposure to secondhand smoke and favorable attitudes toward clean indoor air policies. Our findings suggest the incorporation of anger appeals when promoting clean indoor air policies.

    2013-02-01

    The work was aimed at the evaluation of a cleanliness of pharmaceutical equipments after the end of the production and subsequent cleaning process. The influence of a dirty-hold time, a time interval between the end of the production period and the beginning of the cleaning process on its efficiency and the cleanliness of the equipment has been studied. The evaluation was performed for commercial tablet antihypertensive formulation with API losartan potassium. Sampling was carried out by a wet-swabbing method from the equipments and consequently obtained samples were analytically evaluated using HPLC. In the production of the concerned pharmaceutical, it has been found that the cleaning process is properly designed and validated. Despite the concentration of losartan in swabs from the equipment was in all cases within the limits of acceptance criteria, the effect of the dirty-hold time was proved. In the equipments with long hold-time period, the monitored substance was found in substantially higher concentrations.

    2003-01-01

    During the flights of the University of Washington's Convair-580 in the Southern African Regional Science Initiative (SAFARI 2000) in southern Africa, a phenomenon was observed that has not been reported previously. This was the occurrence of thin layers of remarkably clean air, sandwiched between heavily polluted air, which persisted for many hours during the day. Photographs are shown of these clean air slots (CAS), and particle concentrations and light scattering coefficients in and around such slot are presented. An explanation is proposed for the propensity of CAS to form in southern Africa during the dry season.

    NASA/MSFC has recently acquired new equipment for the manufacture and processing of rubber and rubber containing items that are used in the RSRM (Reusable Solid Rocket Motor) system. Work with a previous generation of rubber equipment at MSFC (Marshall Space Flight Center) in the 1970's had involved the use of ODC's such as 1,1,1-Trichloroethane or VOC's such as Toluene as the solvents of choice in cleaning the equipment. Neither of these options is practical today. This paper addresses the selection and screening of candidate cleaning solvents that are not only effective, but also meet the new environmental standards.

  1. Comparison of materials used for cleaning equipment in retail food premises, and of two methods for the enumeration of bacteria on cleaned equipment and work surfaces

    PubMed Central

    Gilbert, R. J.

    1970-01-01

    There is no official scheme for testing disinfectants and detergent/disinfectants for use in the retail food trade and few recommended procedures have been given for the cleaning of equipment with these agents. Therefore, field trials were carried out in a large self-service store. Comparisons were made of the various cleaning efficiencies, as determined by bacterial plate counts, of detergent and disinfectant solutions and machine cleaning oils applied with either clean cloths or disposable paper towels to items of equipment. The most satisfactory results were always obtained when anionic detergent (0·75% w/v) and hypochlorite (200 p.p.m. available chlorine) solutions were applied in a `two-step' procedure. Tests were made to compare the calcium alginate swab-rinse and the agar sausage (Agaroid) techniques for the enumeration of bacteria on stainless steel, plastic, formica and wooden surfaces before and after a cleaning process. Although recovery rates were always greater by the swab-rinse technique, the agar sausage technique was considered to be a useful routine control method for surface sampling. PMID:4914087

  9. New challenges to air/gas cleaning systems

    SciTech Connect

    Kovach, J.L.

    1997-08-01

    This paper discusses the need for changes in the design and manufacturing of air and gas cleaning systems to meet waste management and site remediation requirements. Current design and manufacturing practices are primarily directed toward evaluating operational problems with existing systems in nuclear reactor facilities. However, nuclear waste management needs have developed which are much broader in scope and have different processing conditions. Numerous examples of air cleaning needs for waste management activities are provided; the major differences from operating facility needs are the requirement for continuous effluent treatment under widely different processing conditions. Related regulatory issues are also discussed briefly. 1 ref.

  10. Measurement of formaldehyde in clean air

    SciTech Connect

    Neitzert, V.; Seiler, W.

    1981-01-01

    A method for the measurement of small amounts of formaldehyde in air has been developed. The method is based on the derivatization of HCHO with 2.4-Denetrophenylhydragine, forming 2.4-Dentrophylhydragine, measured with GC-ECD-technique. HCHO is preconcentrated using a cryogenic sampling technique. The detection limit is 0.05 ppbv for a sampling volume of 200 liter. The method has been applied for measurements in continental and marine air masses showing HCHO mixing ratios of 0.4--5.0 ppbv and 0.2--1.0 ppbv, respectively. HCHO mixing ratios show diurnal variations with maximum values during the early afternoon and minimum values during the early morning. In continental air, HCHO mixing ratios are positively correlated with CO and SO/sub 2/, indicating anthropogenic HCHO sources which are estimated to be 6--11 x 10/sup 12/g/year/sup -1/ on a global scale.

  13. Why business wants the Clean Air Act changed

    SciTech Connect

    Marth, D.

    1982-06-01

    New legislation to modify the Clean Air Act is designed to eliminate the cumbersome requirements that constrain economic growth without lowering present air standards. Environmentalists reject the Luken bill, however, in favor of only fine-tuning the existing Clean Air Act. Ignorance of how the complicated Act works has hampered its implementation by industry. The two sides appear irreconcilable as the debate focuses on the tradeoffs of jobs versus air quality. The Luken bill would ease auto emission requirements enough to lower car prices and reduce unemployment. Environmentalists challenge that claim and seek to tighten specific controls that will reduce the effects of acid rain. President Reagan favors the Luken bill, but political considerations will probably keep the battle concentrated in the House committee. Industry leaders are counting on public pressure to improve both the Act and the economy. (DCK)

  18. Plants Clean Air and Water for Indoor Environments

    NASA Technical Reports Server (NTRS)

    2007-01-01

    Wolverton Environmental Services Inc., founded by longtime government environmental scientist B.C. "Bill" Wolverton, is an environmental consulting firm that gives customers access to the results of his decades of cutting-edge bioremediation research. Findings about how to use plants to improve indoor air quality have been published in dozens of NASA technical papers and in the book, "How to Grow Fresh Air: 50 Houseplants That Purify Your Home or Office." The book has now been translated into 12 languages and has been on the shelves of bookstores for nearly 10 years. A companion book, "Growing Clean Water: Nature's Solution to Water Pollution," explains how plants can clean waste water. Other discoveries include that the more air that is allowed to circulate through the roots of the plants, the more effective they are at cleaning polluted air; and that plants play a psychological role in welfare in that people recover from illness faster in the presence of plants. Wolverton Environmental is also working in partnership with Syracuse University, to engineer systems consisting of modular wicking filters tied into duct work and water supplies, essentially tying plant-based filters into heating, ventilation, and air conditioning (HVAC) systems. Also, the company has recently begun to assess the ability of the EcoPlanter to remove formaldehyde from interior environments. Wolverton Environmental is also in talks with designers of the new Stennis Visitor's Center, who are interested in using its designs for indoor air-quality filters

  17. An introduction to the design, commissioning and operation of nuclear air cleaning systems for Qinshan Nuclear Power Plant

    SciTech Connect

    Xinliang Chen; Jiangang Qu; Minqi Shi

    1995-02-01

    This paper introduces the design evolution, system schemes and design and construction of main nuclear air cleaning components such as HEPA filter, charcoal adsorber and concrete housing etc. for Qinshan 300MW PWR Nuclear Power Plant (QNPP), the first indigenously designed and constructed nuclear power plant in China. The field test results and in-service test results, since the air cleaning systems were put into operation 18 months ago, are presented and evaluated. These results demonstrate that the design and construction of the air cleaning systems and equipment manufacturing for QNPP are successful and the American codes and standards invoked in design, construction and testing of nuclear air cleaning systems for QNPP are applicable in China. The paper explains that the leakage rate of concrete air cleaning housings can also be assured if sealing measures are taken properly and embedded parts are designed carefully in the penetration areas of the housing and that the uniformity of the airflow distribution upstream the HEPA filters can be achieved generally no matter how inlet and outlet ducts of air cleaning unit are arranged.

  18. Cleaning products and air fresheners: exposure to primary and secondary air pollutants

    NASA Astrophysics Data System (ADS)

    Nazaroff, William W.; Weschler, Charles J.

    Building occupants, including cleaning personnel, are exposed to a wide variety of airborne chemicals when cleaning agents and air fresheners are used in buildings. Certain of these chemicals are listed by the state of California as toxic air contaminants (TACs) and a subset of these are regulated by the US federal government as hazardous air pollutants (HAPs). California's Proposition 65 list of species recognized as carcinogens or reproductive toxicants also includes constituents of certain cleaning products and air fresheners. In addition, many cleaning agents and air fresheners contain chemicals that can react with other air contaminants to yield potentially harmful secondary products. For example, terpenes can react rapidly with ozone in indoor air generating many secondary pollutants, including TACs such as formaldehyde. Furthermore, ozone-terpene reactions produce the hydroxyl radical, which reacts rapidly with organics, leading to the formation of other potentially toxic air pollutants. Indoor reactive chemistry involving the nitrate radical and cleaning-product constituents is also of concern, since it produces organic nitrates as well as some of the same oxidation products generated by ozone and hydroxyl radicals. Few studies have directly addressed the indoor concentrations of TACs that might result from primary emissions or secondary pollutant formation following the use of cleaning agents and air fresheners. In this paper, we combine direct empirical evidence with the basic principles of indoor pollutant behavior and with information from relevant studies, to analyze and critically assess air pollutant exposures resulting from the use of cleaning products and air fresheners. Attention is focused on compounds that are listed as HAPs, TACs or Proposition 65 carcinogens/reproductive toxicants and compounds that can readily react to generate secondary pollutants. The toxicity of many of these secondary pollutants has yet to be evaluated. The inhalation

  19. Unequal State Air Pollution: Adopting and Adapting to State Clean Air Policy

    NASA Astrophysics Data System (ADS)

    Glasgow, Derek John

    This dissertation looks at the relationship between American subnational governments and clean air policy in three different cases. I investigate the impact of state reduction policies on the emission of Greenhouse emissions, the subnational adoption of Greenhouse Gas tracking and reduction policies, and the impact of Clean Air Act standards on the siting of coal-fired power plants. The major finding is that in both the adoption and business response to these policies, a state's political context can limit its ability to regulate air pollution. These factors contribute to the unequal protection of air quality across the United States.

    The process through which representative air carriers decide whether or not to purchase flight equipment was investigated as well as their practices and policies in retiring surplus aircraft. An analysis of the flight equipment investment decision process in ten airlines shows that for the airline industry as a whole, the flight equipment investment decision is in a state of transition from a wholly informal process in earliest years to a much more organized and structured process in the future. Individual air carriers are in different stages with respect to the formality and sophistication associated with the flight equipment investment decision.

  4. Ceramic membrane defouling (cleaning) by air Nano Bubbles.

    2016-03-01

    Ceramic membranes are among the most promising technologies for membrane applications, owing to their excellent resistance to mechanical, chemical, and thermal stresses. However, membrane fouling is still an issue that hampers the applications at large scales. Air Nano Bubbles (NBs), due to high mass transfer efficiency, could potentially prevent fouling of ceramic membrane filtration processes. In this study, bench and pilot scale ceramic membrane filtration was performed with air NBs to resist fouling. To simulate fouling, humic acid, as an organic foulant, was applied to the membrane flat sheet surface. Complete membrane clogging was achieved in less than 6 h. Membrane defouling (cleaning) was performed by directly feeding of air NBs to the membrane cells. The surface of the ceramic membrane was superbly cleaned by air NBs, as revealed by atomic force microscope (AFM) images before and after the treatment. The permeate flux recovered to its initial level (e.g., 26.7 × 10(-9) m(3)/m(2)/s at applied pressure of 275.8 kPa), which indicated that NBs successfully unclogged the pores of the membrane. The integrated ceramic membrane and air NBs system holds potential as an innovative sustainable technology.

    2002-11-01

    A laboratory pilot study has been undertaken with the material that showed the most promise (high capacity and low pressure drop) based on the literature review and associated calculations. The best-performing air cleaner was a commercially available pleated filter that contained a thin layer of small activated carbon particles between two sheets of non-woven fibrous webbing. We will refer to this unit as the ''ozone filter'' although it is marketed for removal of volatile organic compounds (VOCs) from automobile passenger compartments. This pilot study strongly suggests that ozone air cleaning can be practical in commercial air handling systems; however, further tests are needed to assess air cleaner performance under a wider range of conditions.

    1994-12-02

    The UO{sub 3} Plant went through a clean out leading to the deactivation of the facility. This clean out consisted of three phases. Phase 1 consisted of the removal of residual process material and the deactivation of most process equipment and instrumentation. Phase 2 consisted of the fixing or removal of contamination so storm water processing would be no longer required. Phase 3 consisted of the remaining activities that had to be completed before the facility was turned over to the Surplus Facility Program. Since the activities of Phase 2 and 3 were closely related, these two phases were worked simultaneously. The first part of this document summarizes the Phase 1 clean out procedures and their results. Phase 1 was completed on February 28, 1994. The second part summarizes the Phase 2/3 clean out procedures and their results. Phase 2/3 was completed before December 31, 1994. Because tanks and equipment were flushed simultaneously or in a specific sequence, the clean out processes are discussed per workplan.

    Microbial contamination of peanut butter by Salmonella poses a significant health risk as Salmonella may remain viable throughout the product shelf life. Effective cleaning and sanitation of processing lines are essential for preventing cross-contamination. The objective of this study was to evaluate the efficacy of a cleaning and sanitation procedure involving hot oil and 60% isopropanol, ± quaternary ammonium compounds, to decontaminate pilot-scale processing equipment harboring Salmonella. Peanut butter inoculated with a cocktail of four Salmonella serovars (∼ 7 log CFU/g) was used to contaminate the equipment (∼ 75 L). The system was then emptied of peanut butter and treated with hot oil (90 °C) for 2 h followed by sanitizer for 1 h. Microbial analysis of food-contact surfaces (7 locations), peanut butter, and oil were conducted. Oil contained ∼ 3.2 log CFU/mL on both trypticase soy agar with yeast extract (TSAYE) and xylose lysine deoxycholate (XLD), indicating hot oil alone was not sufficient to inactivate Salmonella. Environmental sampling found 0.25-1.12 log CFU/cm(2) remaining on processing equipment. After the isopropanol sanitation (± quaternary ammonium compounds), no Salmonella was detected in environmental samples on XLD (<0.16 log CFU/cm(2)). These data suggest that a two-step hot oil clean and isopropanol sanitization treatment may eliminate pathogenic Salmonella from contaminated equipment.

    Inadequate cleaning of a pharmaceutical manufacturing plant or inadequate purging of the individual pieces of equipment used in multi-product manufacturing or equipment not dedicated to individual products may lead to contamination of the next batch of pharmaceutics manufactured using the same equipment. Challenges for cleaning validation are encountered especially when developing sensitive analytical methods capable of detecting traces of active pharmaceutical ingredients that are likely to remain on the surface of the pharmaceutical equipment after cleaning. A method's inability to detect some residuals could mean that either the method is not sensitive enough to the residue in question or the sampling procedure is inadequate. A sensitive and reproducible reversed-phase, high-performance liquid chromatographic method was developed for the determination of ofloxacin in swab samples. The method for determining ofloxacin residues on manufacturing equipment surfaces was validated in regard to precision, linearity, accuracy, specificity, limit of quantification, and percent recovery from the equipment surface, as well as the stability of a potential contaminant in a cleaning validation process. The active compound was selectively quantified in a sample matrix and swab material in amounts as low as 0.55 ng/mL. The swabbing procedure using cotton swabs was validated. A mean recovery from stainless steel plate of close to 85% was obtained. Chromatography was carried out on a pre-packed Merck (Dermstadt, Germany) Lichrospher model 100 Rp-18 (5.0 microm, 250 mm X 4.0 mm) column using a mixture of sodium lauryl sulfate (0.024% aqueous solution), acetonitrile, and glacial acetic acid (500:480:20,v/v) as the mobile phase at a flow rate of 1.5 mL/min with a column temperature of 35 degrees C and 294 nm detection. The assay was linear over the concentration range of 2 ng/mL to 2000 ng/mL (R approximately 0.99998). The method was validated for accuracy and precision. The

    1998-12-31

    On March 12, 1996, the EPA promulgated the new Source Performance Standards (NSPS) for Municipal Solid Waste (MSW) Landfills, the first federal air regulation specifically for MSW landfills. Landfills subject to this regulation which exceeded the threshold design capacity also became subject to the Title V operating permit program. This began the application of the Clean Air Act (CAA) to most of these nontraditional air sources. Unlike landfills, typical air sources have easily defined input capacities that correspond to potential emissions while the process creates a product or output. All these concepts are difficult and confusing to apply to MSW landfills. Applicability of the following CAA regulations are specifically addressed in this paper: NSPS for MSW landfills; new Source Review (NSR)/Prevention of Significant Deterioration (PSD); landfill Maximum Achievable Control Technologies (MACT); 112(g) Modification of Major Sources of Hazardous Air Pollutants (HAP); 112(r) Accidental Release Prevention; and Title V. Along with summarizing the potential applicability of each, the main issues are presented along with the current information on the regulations.

    We have, in cooperation with industry, developed high-efficiency filters made from sintered stainless-steel fibers for use in several air-cleaning applications in the nuclear industry. These filters were developed to overcome the failure modes in present high-efficiency particulate air (HEPA) filters. HEPA filters are made from glass paper and glue, and they may fail when they get hot or wet and when they are overpressured. In developing our steel filters, we first evaluated the commercially available stainless-steel filter media made from sintered powder and sintered fiber. The sintered-fiber media performed much better than sintered-powder media, and the best media had the smallest fiber diameter. Using the best media, we then built prototype filters for venting compressed gases and evaluated them in our automated filter tester. 12 refs., 20 figs.

    Vehicle cabs equipped with an effective air cleaning and pressurization system, fitted to agricultural and off-road machineries, isolate drivers from the polluted environment, in which they are likely to work. These cabs provide protection against particulate and gaseous pollutants generated by these types of work activities. Two laboratory methods have been applied to determining the performance characteristics of two cabs of different design, namely, optical counting-based measurement of a potassium chloride (KCl) aerosol and fluorescein aerosol-based tracing. Results of cab confinement efficiency measurements agreed closely for these two methods implemented in the study. Measurements showed that high confinement efficiencies can be achieved with cabs, which are properly designed in ventilation/cleaning/airtightness terms. We also noted the importance of filter mounting airtightness, in which the smallest defect is reflected by significant degradation in cab performance. Determination of clean airflow rate by monitoring the decrease in test aerosol concentration in the test chamber gave excellent results. This method could represent an attractive alternative to methods involving gas tracing or air velocity measurement at blowing inlets.

    In May 1988, the Pennsylvania Electric Company (Penelec) and New York State Electric and Gas Corporation (NYSEG) were awarded a contract from the Department of Energy's Pittsburgh Energy and Technology Center (DOE-PETC) to evaluate the performance of a two-inch Air-Sparged Hydrocyclone (ASH) for cleaning fine minus-100-mesh coal. A 24-month study was successfully completed, optimizing the performance of the ASH for cleaning raw classified, naturally-occurring minus-100-mesh Upper Freeport coal, and comparing its performance with Advanced Froth Flotation (AFF), a procedure utilizing conventional flotation equipment operated in an advanced manner (low impeller speeds, starvation float, multiple-stage cleaning, etc.) with highly selective reagents to optimize ash and pyritic sulfur rejection. The economics of cleaning fine coal by both processes at commercial scale, for retrofit and greenfield applications were found to be comparable within the accuracy of the study. Technical performance of the two processes were also found to be essentially identical. Thus, the ASH would be the best choice for a retrofit installation into an existing plant because of requiring less space. Both processes were successful in achieving excellent separations when cleaning the Upper Freeport coal. Both the ASH and AFF circuits were able to produce a clean-coal product of yield (65--80 percent weight recovery) and quality (5--6 percent ash) equivalent to that as theoretically determined by float-sink washability analyses. Combining either of the two fine coal flotation processes with a classifying cyclone circuit resulted in pyritic sulfur rejection values of about 85 percent. 47 refs., 109 figs., 75 tabs.

    SECTION 608 of the Clean Air Act Amendments has altered much of the refrigeration service contracting industry. MCLR Project Number 660-52502 was established to examine two areas where the Amendments are influencing contractors to determine if more cost-effective service procedures might be developed. One area where existing service procedures are being revisited involves the removal of contaminants from a refrigeration system after a motor burnout. At one time, a Class 1 substance such as CFC-11 or CFC-113 was used as a flushing agent for cleaning a system after a burnout. On large systems, the compressor was disassembled, and the parts were cleaned using 1,1,1-trichloroethane (TCA) or a TCA-containing mixture. Such alternatives are seldom possible today, as the manufacture of Class 1 substances was banned on January 1, 1996. This report describes processes for mineral oil removal, process alternatives for servicing burnouts, solvents, and laboratory retrofit tests.

    1998-02-01

    A capillary gas chromatographic method is described for the determination of methenamine hippurate residue in swabs collected from manufacturing equipment surfaces. Any residual methenamine hippurate remaining on process equipment after cleaning is removed by swabbing with one wet polyester Absorbond swab (4" x 4") pre-moistened with water followed by a dry Absorbond swab. The residual methenamine hippurate is chromatographed on a 30 x 0.32 mm (i.d.) Supelcowax-10 capillary column of 0.25-micron film thickness. The amount of residual methenamine hippurate is determined by comparing the ratio of methenamine hippurate peak area response to that of p-cresol (internal standard) obtained for the sample to a linear calibration curve obtained for a series of standard solutions. The method is demonstrated to be sufficiently linear, accurate, precise, sensitive and rugged for the determination of low levels of methenamine hippurate on equipment surfaces. Using this method, the mean recovery of methenamine hippurate from spiked Absorbond swab samples contained in high density polyethylene bottles was 105.2%, with a relative standard deviation (RSD) of +/- 7.1% (n = 25). The mean recoveries of methenamine hippurate from spiked test plates for '180 Grit' Stainless Steel, Teflon and WARCO White (neoprene and PVC) gasket material were 77.2, 96.1 and 50.6%, with RSDs of +/- 9.4 (n = 25), +/- 4.3 (n = 25) and +/- 36% (n = 20), respectively. Recovery correction factors have been incorporated into the method. The method was successfully applied to the assay of actual equipment cleaning validation swab samples. Stability studies demonstrate that methenamine hippurate is not very stable on the equipment surfaces or in the swabs. It is recommended that the surfaces be swabbed immediately after cleaning and the swabs analyzed within 24 h after sample collection. The results demonstrate that in order to fully validate the cleaning procedures, it is not only necessary to investigate the

Three systems designed for 90% efficient removal (a venturi scrubber, a submerged gravel scrubber and a spray scrubber) were compared. The submerged gravel scrubber and the venturi scrubber were rated as prime candidates. Four systems designed for 99% removal efficiency (the two optimum scrubbers chosen for 90% removal efficiency fitted with fibrous elements, a sand and gravel filter and a HEPA filter bank) were compared. The tI~ scrubbers were again rated as prime candidates. Both the sand and gravel filter and the HEPA filter bank were found to be excessively large and costly. Considerable experience supports the use of the optimum scrubber systems and it is concluded that their use is technically feasible for the FFTF containment margins application.

  9. Cleaning practices and cleaning products in nurseries and schools: to what extent can they impact indoor air quality?

    PubMed

    Wei, W; Boumier, J; Wyart, G; Ramalho, O; Mandin, C

    2016-08-01

    In the framework of a nationwide survey on indoor air quality conducted from September 2009 to June 2011 in 310 nurseries, kindergartens, and elementary schools in all regions of France, cleaning practices and products were described through an extensive questionnaire completed on-site by expert building inspectors. The questionnaire included the cleaning frequencies and periods, cleaning techniques, whether windows were open during cleaning, and the commercial names of the products used. Analysis of the questionnaire responses showed that cleaning was generally performed daily for furniture and floors. It was performed mostly in the evening with wet mopping and with one or more windows open. Five hundred eighty-four different cleaning products were listed, among which 218 safety data sheets (SDSs) were available and analyzed. One hundred fifty-two chemical substances were identified in the SDSs. The typical substances in cleaning products included alcohols, chlorides, terpenes, aldehydes, and ethers; more than half of them are irritants. Two endocrine disruptors, 2-phenylphenol and Galaxolide, were identified in two cleaning products used every day to clean the floors, in seven kindergartens and in a nursery respectively. Eleven reactive substances containing C=C double bonds, mostly terpenes, were identified in a wide variety of cleaning products.

    The U.S. Department of Energy awarded Loyola University Chicago and the Institute of Environmental Sustainability (IES) $486,000.00 for the proposal entitled “Chicago clean air, clean water project: Environmental monitoring for a healthy, sustainable urban future.” The project supported the purchase of analytical instruments for the development of an environmental analytical laboratory. The analytical laboratory is designed to support the testing of field water and soil samples for nutrients, industrial pollutants, heavy metals, and agricultural toxins, with special emphasis on testing Chicago regional soils and water affected by coal-based industry. Since the award was made in 2010, the IES has been launched (fall 2013), and the IES acquired a new state-of-the-art research and education facility on Loyola University Chicago’s Lakeshore campus. Two labs were included in the research and education facility. The second floor lab is the Ecology Laboratory where lab experiments and analyses are conducted on soil, plant, and water samples. The third floor lab is the Environmental Toxicology Lab where lab experiments on environmental toxins are conducted, as well as analytical tests conducted on water, soil, and plants. On the south end of the Environmental Toxicology Lab is the analytical instrumentation collection purchased from the present DOE grant, which is overseen by a full time Analytical Chemist (hired January 2016), who maintains the instruments, conducts analyses on samples, and helps to train faculty and undergraduate and graduate student researchers.

    Sheldon, L. S.; Keever, J.

    1985-01-01

    The environment of the HALOE assembly clean room at NASA Langley Research Center is analyzed to determine the background levels of airborne organic compounds. Sampling is accomplished by pumping the clean room air through absorbing cartridges. For volatile organics, cartridges are thermally desorbed and then analyzed by gas chromatography and mass spectrometry, compounds are identified by searching the EPA/NIH data base using an interactive operator INCOS computer search algorithm. For semivolatile organics, cartridges are solvent entracted and concentrated extracts are analyzed by gas chromatography-electron capture detection, compound identification is made by matching gas chromatogram retention times with known standards. The detection limits for the semivolatile organics are; 0.89 ng cu m for dioctylphlhalate (DOP) and 1.6 ng cu m for polychlorinated biphenyls (PCB). The detection limit for volatile organics ranges from 1 to 50 parts per trillion. Only trace quantities of organics are detected, the DOP levels do not exceed 2.5 ng cu m and the PCB levels do not exceed 454 ng cu m.

    This field campaign funded the participation of scientists from seven different research groups and operated over thirty instruments during the Winter Intensive Operating Period (January-February 2012) of the Clean Air for London (ClearfLo) campaign. The campaign took place at a rural site in Detling, UK, 45 kilometers southeast of central London. The primary science questions for the ClearfLo winter IOP (intensive operational periods) were: 1) “what is the urban increment of particulate matter (PM) and other pollutants in the greater London area?” and 2) “what is the contribution of solid fuel use for home heating to wintertime PM?” An additional motivation for the Detling measurements was the question of whether coatings on black carbon particles enhance absorption.

    In the future, we may be able use air cleaning systems and reduce rates of ventilation (i.e., reduce rates of outdoor air supply) to save energy, with indoor air quality (IAQ) remaining constant or even improved. The opportunity is greatest for commercial buildings because they usually have a narrower range of indoor pollutant sources than homes. This article describes the types of air cleaning systems that will be needed in commercial buildings.

  1. Optimizing electric utility air toxics compliance with other titles of the Clean Air Act

    SciTech Connect

    Loeb, A.P.; South, D.W.

    1993-12-31

    This paper provides an overview of regulatory issues under Title III of the Clean Air Act Amendments that could affect electric utilities. Title III contains provisions relating to hazardous air pollutants (HAPs) and provides special treatment for electric utilities. Generally, this discussion documents that if utility toxic emissions are regulated, one of the chief difficulties confronting utilities will be the lack of coordination between Title III and other titles of the Act. The paper concludes that if the US Environmental Protection Agency (EPA) determines that regulation of utility HAPs is warranted under Title III, savings can be realized from flexible compliance treatment.

    Barile, Ronald G.; Fogarty, Chris; Cantrell, Chris; Melton, Gregory S.

    1994-01-01

    NASA personnel at Kennedy Space Center's Material Science Laboratory have developed new environmentally sound precision cleaning and verification techniques for systems and components found at the center. This technology is required to replace existing methods traditionally employing CFC-113. The new patent-pending technique of precision cleaning verification is for large components of cryogenic fluid systems. These are stainless steel, sand cast valve bodies with internal surface areas ranging from 0.2 to 0.9 sq m. Extrapolation of this technique to components of even larger sizes (by orders of magnitude) is planned. Currently, the verification process is completely manual. In the new technique, a high velocity, low volume water stream impacts the part to be verified. This process is referred to as Breathing Air/Water Impingement and forms the basis for the Impingement Verification System (IVS). The system is unique in that a gas stream is used to accelerate the water droplets to high speeds. Water is injected into the gas stream in a small, continuous amount. The air/water mixture is then passed through a converging/diverging nozzle where the gas is accelerated to supersonic velocities. These droplets impart sufficient energy to the precision cleaned surface to place non-volatile residue (NVR) contaminants into suspension in the water. The sample water is collected and its NVR level is determined by total organic carbon (TOC) analysis at 880 C. The TOC, in ppm carbon, is used to establish the NVR level. A correlation between the present gravimetric CFC113 NVR and the IVS NVR is found from experimental sensitivity factors measured for various contaminants. The sensitivity has the units of ppm of carbon per mg/sq ft of contaminant. In this paper, the equipment is described and data are presented showing the development of the sensitivity factors from a test set including four NVRs impinged from witness plates of 0.05 to 0.75 sq m.

    1981-08-01

    The effect of laminar air flow conditions and clean-room dress on the microbial contamination rates of intravenous admixtures was investigated. Intravenous admixtures were prepared by one investigator using aseptic technique under four environmental conditions: laminar air flow conditions with clean-room dress; laminar air flow without clean-room dress; clean table top with clean-room dress; and clean table top without clean-room dress. In each environmental condition, 350 admixtures were compounded. Negative-control samples (n = 150) were also tested, as were 10 positive-control samples. Samples were tested in each of two growth media and incubated at 35 degrees C for 14 days or until growth occurred. The incidence of contamination of admixtures compounded in laminar air flow conditions was significantly less than the contamination of those compounded on a clean table top (p less than 0.05) regardless of the operator's dress. The incidence of contamination of admixtures compounded while wearing clean-room dress was not significantly different from those prepared while not wearing clean-room dress regardless of the environment in which the admixture was prepared. The overall low level of contamination [0.79% (11/1400)] was inconclusive regarding the effect of dress on the incidence of contamination when admixtures were prepared under LAF conditions. It is concluded that, when one adheres to aseptic technique, the environment in which admixtures are compounded is the most important variable affecting the microbial contamination rate.

  6. BACT analysis under the Clean Air Act's PCD program

    Simms, P.; Walke, J.

    2006-11-15

    Before a company may build a new major industrial source of air pollution, or make modifications to an existing major source in the USA it must apply for and receive a Clean Air Act (CAA) Prevention of Significant Deterioration (PSD) permit. State environmental agencies typically issue such permits, either under state law or by exercising delegated authority to implement the federal PSD program. To fully comply with the CAA, the emissions limits identified as BACT must incorporate consideration of more than just add-on emissions control technology, they must also reflect appropriate considerations of fuel quality (e.g. low-sulfur coal) and process changes (e.g. advanced combustion techniques) as a means of controlling emissions, and must consider the other environmental and public welfare benefits of the identified emissions control options. Several states including New Mexico and Illinois have already determined that innovated technologies, such as Integrated Gasification Combined Cycle (IGCC), must be considered in connection with the BACT analysis for new coal-fired power plants. Even the notion that BACT is categorically limited in scope to the general type of facility proposed is contrary to EPA precedent. For example, the Environmental Appeals Board (EAB) has explained that permitting authorities retain the discretion under the definition of BACT to require dramatically different facility designs (e.g. a natural gas plant instead of a coal-fired power plant). The best advice for any permit applicant is to include in the BACT analysis a careful and honest examination of better performing alternative processes and/or innovative combustion techniques and to aggressively pursue such options wherever feasible. 17 refs.

  7. Highlights of the Clean Air Act Amendments of 1990

    SciTech Connect

    Lee, B.

    1991-01-01

    The amendments to the Clean Air Act provide for operating permits for stationary sources of pollution, marking a change that is comparable to federal water pollution regulations. The bill addresses acid rain emissions and will phase out production of chemicals contributing to depletion of the stratospheric ozone layer. A major new concept incorporated into the emission limits established by law is a system of tradeable emissions credits. If a facility reduces emissions below the standard or ahead of the timetable set by law, emissions credits are earned that can be applied to future emissions or sold to another facility. The bill also provides strict deadlines for the EPA to meet in promulgating the regulations. These deadlines will seriously strain the personnel and financial resources of the agency. Perhaps the most significant of the miscellaneous items in the law is a provision for extended unemployment benefits under the Job Training Partnership Act for workers who lose their jobs because of the law's provisions. However, this is contingent on the displaced workers' seeking job retraining.

  8. The Clean Air Act impacts on rail coal

    SciTech Connect

    Sharp, R.G. )

    1991-03-01

    These factors are examined in this article. In November 1990, President Bush signed the Clean Air Act amendments of 1990 into law. Title IV, concerning acid rain control, calls for a two-phase reduction in power plant sulfur-dioxide emissions, culminating in a nationwide cap after the year 2000. A large part of this reduction will be obtained through substituting low-sulfur coals for the higher-sulfur fuels now used. Most commentators have characterized this legislation as a boon for low-sulfur coal producers and the railroads serving them. If, as projected, up to one-eighth of existing coal-burning plants shift to more distant suppliers, a surge in rail traffic would ensue. Whether this traffic originates at eastern or western mines, rail carriers would obtain longer hauls and greater coal volumes. We have examined the rail transport implications of the amendments and found that the potential rail benefits may be exaggerated. Although traffic volume will grow, margins on some new traffic are likely to be eroded by continued rate competition and reduced productivity. To satisfy coal transport needs in the 1990s, factors that challenge rail productivity must be recognized and resolved.

  9. The Canadian Clean Air Regulatory Agenda Mercury Science Program.

    Morrison, Heather A

    2011-10-01

    The Clean Air Regulatory Agenda (CARA) Mercury Science Program was developed to provide scientific information to support regulatory activities and accountability pertaining to atmospheric emissions of mercury in Canada. The first phase of the science program, entitled "Setting-the-Baseline", sought to achieve the following: identify key indicators of the state-of-the-Canadian environment with respect to the transport, fate and effects of mercury; define these indicators; and, understand the processes that relate these indicators to anthropogenic emissions of mercury. To achieve these outcomes, a consultative process was used to identify the scientific needs of the agenda for mercury; understand Canada's scientific capacity; and, develop a plan to fulfill these scientific needs. The science plan that emerged from this process was structured around the themes of atmospheric monitoring, landscape-based risk assessment, ecological risk assessment, ecosystem modeling, and trends. Implementation of the science plan necessitated a multi-disciplinary and extensively partnered program. To date, the CARA Mercury Science Program is producing coordinated science at the national-scale that aims to directly assess the effectiveness of the CARA for mercury and for many of Canada's other mercury-related policies.

    The research carried out in this project focuses on developing novel volatile organic compounds (VOCs) air cleaning technologies needed to enable energy-saving reductions in ventilation rates. we targeted a VOC air cleaning system that could enable a 50% reduction in ventilation rates. In a typical commercial HVAC system that provides a mixture of recirculated and outdoor air, a VOC air cleaner in the supply airstream must have a 15% to 20% VOC removal efficiency to counteract a 50% reduction in outdoor air supply.

    Haze formation on the patterned metal surface of reticles is a known problem for IC manufacturers that can impact device yield and increase operational costs due to the need for more frequent cleaning of the reticles. Storage of reticles in an ultraclean environment can reduce haze formation and reduce operational costs. We examined the contamination levels of a new type of reticle stocker that stores reticles in microenvironments which are continuously purged with extreme clean dry air (XCDA). Each microenvironment consists of twelve vertically stacked reticle storage slots which can be opened at any slot. The design of the microenvironment includes an XCDA supply that provides a homogeneous horizontal flow of XCDA between the reticles. Figure 1. Reduction of contamination levels inside the storage microenvironment as a function of XCDA flow rate. As shown in Fig. 1, continuous XCDA purge reduces the contaminant levels inside the microenvironment. The amount of reduction depends on the XCDA purge flow rate and the chemical species. Volatile organic substances can be reduced by more than two orders of magnitude. Humidity is reduced less because the plastic material of the storage microenvironment incorporates water in its matrix and can release moisture to the extremely dry atmosphere. Chemical filters applied to mini- or microenvironments typically reduce the contaminant levels only by 95-99% and do not reduce the humidity. To pick and place reticles, the reticle storage microenvironment must be opened. The transient contaminant levels inside the empty microenvironment show an increase at the moment when the microenvironment is opened. Under the given conditions, the microenvironment returns to equilibrium levels with a time constant of 105 seconds (see Fig. 2). Similar dynamic response was measured for IPA and acetone. Figure 2.

  5. Keeping the Air Clean and Safe: An Anthrax Smoke Detector

    NASA Technical Reports Server (NTRS)

    2005-01-01

    Scientists at work in the Planetary Protection division at NASA s Jet Propulsion Laboratory (JPL) sterilize everything before blasting it to the Red Planet. They take great pains to ensure that all spacecraft are void of bacterial life, especially the microscopic bacteria that can live hundreds of years in their spore states. No one is quite sure what Earthly germs would do on Mars, but scientists agree that it is safest to keep the Martian terrain as undisturbed as possible. Errant Earth germs would also render useless the instruments placed on exploration rovers to look for signs of life, as the life that they registered would be life that came with them from Earth. A team at JPL, headed by Dr. Adrian Ponce, developed a bacterial spore-detection system that uses a simple and robust chemical reaction that visually alerts Planetary Protection crews. It is a simple air filter that traps micron-sized bacterial spores and then submits them to the chemical reaction. When the solution is then viewed under an ultraviolet light, the mixture will glow green if it is contaminated by bacteria. Scientists can then return to the scrubbing and cleaning stages of the sterilization process to remove these harmful bacteria. The detection system is the space-bound equivalent of having your hands checked for cleanliness before being allowed to the table; and although intended to keep terrestrial germs from space, this technology has awesome applications here on Mother Earth. The bacterial spore-detection unit can recognize anthrax and other harmful, spore-forming bacteria and alert people of the impending danger. As evidenced in the anthrax mailings of fall 2001 in the United States, the first sign of anthrax exposure was when people experienced flu-like symptoms, which unfortunately, can take as much as a week to develop after contamination. Anthrax cost 5 people their lives and infected 19 others; and the threat of bioterrorism became a routine concern, with new threats popping up

    Bell, Geoffrey C.; Storey, Bill; Patterson, Michael K.

    2009-09-30

    The goal of this demonstration was to show how sensors in IT equipment could be accessed and used to directly control computer room air conditioning. The data provided from the sensors is available on the IT network and the challenge for this project was to connect this information to the computer room air handler's control system. A control strategy was developed to enable separate control of the chilled water flow and the fans in the computer room air handlers. By using these existing sensors in the IT equipment, an additional control system is eliminated (or could be redundant) and optimal cooling can be provided saving significant energy. Using onboard server temperature sensors will yield significant energy reductions in data centers. Intel hosted the demonstration in its Santa Clara, CA data center. Intel collaborated with IBM, HP, Emerson, Wunderlich-Malec Engineers, FieldServer Technologies, and LBNL to install the necessary components and develop the new control scheme. LBNL also validated the results of the demonstration.

    2004-02-01

    There are 188 air toxics listed as hazardous air pollutants (HAPs) in the Clean Air Act (CAA), based on their potential to adversely impact public health. This paper presents several analyses performed to screen potential candidates for addition to the HAPs list. We analyzed 1086 HAPs and potential HAPs, including chemicals regulated by the state of California or with emissions reported to the Toxics Release Inventory (TRI). HAPs and potential HAPs were ranked by their emissions to air, and by toxicity-weighted (tox-wtd) emissions for cancer and noncancer, using emissions information from the TRI and toxicity information from state and federal agencies. Separate consideration was given for persistent, bioaccumulative toxins (PBTs), reproductive or developmental toxins, and chemicals under evaluation for regulation as toxic air contaminants in California. Forty-four pollutants were identified as candidate HAPs based on three ranking analyses and whether they were a PBT or a reproductive or developmental toxin. Of these, nine qualified in two or three different rankings (ammonia [NH3], copper [Cu], Cu compounds, nitric acid [HNO3], N-methyl-2-pyrrolidone, sulfuric acid [H2SO4], vanadium [V] compounds, zinc [Zn], and Zn compounds). This analysis suggests further evaluation of several pollutants for possible addition to the CAA list of HAPs.

  13. Air Pollution Studies in Metromanila and Catalysis Technology Towards Clean Air Philippines

    NASA Astrophysics Data System (ADS)

    Gallardo, S. M.

    - Considerable air quality and emission data gathered in Metropolitan Manila (MM) led to the development of automobile exhaust treatment catalysts as well as their continued improvement. Findings of a 5-year (1993-1998) collaborative work on the development of base metal oxide catalysts for automobile exhaust are summarized here. One study in 1991 reveals an average 16% increase in the number of motor vehicles in MM where 16% are new and the rest are old ones. Another study in 1992 shows the CO and hydrocarbon emission levels from different types of motor vehicles in MM as a function of the age of the vehicle, type of fuel, and the operating condition. Reports of the Department of Environment and Natural Resources (DENR) and other related studies also provided data showing the quality of air in MM. Currently, there are several requirements to further improve the catalyst performance towards the reduction of NOX and to develop catalyst-sorbent for simultaneous NOX-SOX removal. This is so because of the present condition of rain acidification that is found in certain places in MM. These air quality and emission data are needed not only to establish practical emission standards for motor vehicles and the stationary industries and power plants but also in the development of technologies for air pollution control and other clean technologies for cleaner air in the country.

  10. Effectiveness of HVAC duct cleaning procedures in improving indoor air quality.

    PubMed

    Ahmad, I; Tansel, B; Mitrani, J D

    2001-12-01

    Indoor air quality has become one of the most serious environmental concerns as an average person spends about 22 hr indoors on a daily basis. The study reported in this article, was conducted to determine the effectiveness of three commercial HVAC (Heating Ventilation Air Conditioning) duct cleaning processes in reducing the level of airborne particulate matter and viable bioaerosols. The three HVAC sanitation processes were: (1) Contact method (use of conventional vacuum cleaning of interior duct surfaces); (2) Air sweep method (use of compressed air to dislodging dirt and debris); (3) Rotary brush method (insertion of a rotary brush into the ductwork to agitate and dislodge the debris). Effectiveness of these sanitation processes was evaluated in terms of airborne particulate and viable bioaerosol concentrations in residential homes. Eight identical homes were selected in the same neighborhood. Two homes were cleaned using each procedure and two were used as controls. It was found that both particle count readings and bioaerosol concentrations were higher when cleaning was being performed than before or after cleaning, which suggests that dirt, debris and other pollutants may become airborne as a result of disturbances caused by the cleaning processes. Particle count readings at 0.3 micron size were found to have increased due to cigarette smoking. Particle counts at 1.0 micron size were reduced due to HVAC duct cleaning. Post-level bioaerosol concentrations, taken two days after cleaning, were found to be lower than the pre-level concentrations suggesting that the cleaning procedures were effective to some extent. Homes cleaned with the Air Sweep procedure showed the highest degree of reduction in bioaerosol concentration among the three procedures investigated.

    This environmental assessment (EA) was prepared by the U.S.Department of Energy (DOE), with compliance with the National Environmental Policy Act (NEPA) of 1969, Council on Environmental Quality (CE) regulations for implementating NEPA (40 CFR 1500-1508) and DOE regulations for compliance with NEPA (10 CFR 1021), to evaluate the potential environmental impacts associated with a proposed demonstration project to be cost-shared by DOE and Custom Coals International (CCI) under the Clean Coal Technology (CCT) Demonstration Program of DOE`s Office of Fossil Energy. CCI is a Pennsylvania general partnership located in Pittsburgh, PA engaged in the commercialization of advanced coal cleaning technologies. The proposed federal action is for DOE to provide, through a cooperative agreement with CCI, cost-shared funding support for the land acquisition, design, construction and demonstration of an advanced coal cleaning technology project, {open_quotes}Self-Scrubbing Coal: An Integrated Approach to Clean Air.{close_quotes} The proposed demonstration project would take place on the site of the presently inactive Laurel Coal Preparation Plant in Shade Township, Somerset County, PA. A newly constructed, advanced design, coal preparation plant would replace the existing facility. The cleaned coal produced from this new facility would be fired in full-scale test burns at coal-fired electric utilities in Indiana, Ohio and PA as part of this project.

    Objectives. We examined the effects of key political institutional factors on the advancement of state-level clean indoor air laws. Methods. We performed an observational study of state-level clean indoor air law enactment among all 50 US states from 1993 to 2010 by using extended Cox hazard models to assess risk of enacting a relevant law. Results. During the 18-year period from 1993 to 2010, 28 states passed a law covering workplaces, 33 states passed a law covering restaurants, 29 states passed a law covering bars, and 16 states passed a law covering gaming facilities. States with term limits had a 2.15 times greater hazard (95% confidence interval [CI] = 1.27, 3.65; P = .005) of enacting clean indoor air laws. The presence of state-level preemption of local clean indoor air laws was associated with a 3.26 times greater hazard (95% CI = 1.11, 9.53; P = .031) of state-level policy enactment. In the presence of preemption, increased legislative professionalism was strongly associated (hazard ratio = 3.28; 95% CI = 1.10, 9.75; P = .033) with clean indoor air law enactment. Conclusions. Political institutional factors do influence state-level clean indoor air law enactment and may be relevant to other public health policy areas. PMID:24825239

  15. Self-Scrubbing Coal -- an integrated approach to clean air

    SciTech Connect

    Harrison, K.E.

    1997-12-31

    Carefree Coal is coal cleaned in a proprietary dense-media cyclone circuit, using ultrafine magnetite slurries, to remove noncombustible material, including up to 90% of the pyritic sulfur. Deep cleaning alone, however, cannot produce a compliance fuel from coals with high organic sulfur contents. In these cases, Self-Scrubbing Coal will be produced. Self-Scrubbing Coal is produced in the same manner as Carefree Coal except that the finest fraction of product from the cleaning circuit is mixed with limestone-based additives and briquetted. The reduced ash content of the deeply-cleaned coal will permit the addition of relatively large amounts of sorbent without exceeding boiler ash specifications or overloading electrostatic precipitators. This additive reacts with sulfur dioxide (SO{sub 2}) during combustion of the coal to remove most of the remaining sulfur. Overall, sulfur reductions in the range of 80--90% are achieved. After nearly 5 years of research and development of a proprietary coal cleaning technology coupled with pilot-scale validation studies of this technology and pilot-scale combustion testing of Self-Scrubbing Coal, Custom Coals Corporation organized a team of experts to prepare a proposal in response to DOE`s Round IV Program Opportunity Notice for its Clean Coal Technology Program under Public Law 101-121 and Public Law 101-512. The main objective of the demonstration project is the production of a coal fuel that will result in up to 90% reduction in sulfur emissions from coal-fired boilers at a cost competitive advantage over other technologies designed to accomplish the same sulfur emissions and over naturally occurring low sulfur coals.

  16. Further bacteriological evaluation of the TOUL mobile system delivering ultra-clean air over surgical patients and instruments.

    Thore, M; Burman, L G

    2006-06-01

    Two mobile TOUL-400 units (types 1 and 2) that produce an exponential ultra-clean air flow (EUA) via a mobile screen were evaluated (maximum height from floor to centre of screen: type 1, 1.4m; type 2, 1.6m). Bacterial deposition rates were lowered by >60% (P=0.001) over a table area of 1.7 m (length)x1.0m (width) with the TOUL-400 type 1 unit, and the mean air count at 1.0m from the screen was reduced from 23 to 1.6 colony-forming units (CFU)/m3 in experiments in a room with six air changes/h (ACH). The corresponding reductions were two- to three-fold greater in an operating room (OR) with 16 ACH due to higher bacterial contamination levels in the control experiments. The dramatic but localized reduction of the deposition rate recorded on one 14-cm settle plate (>2376-fold at 0.8m from the screen in the OR) apparently reflected the focus of the EUA. The impact of the TOUL-400 unit was underestimated by almost 100-fold by the air counts of bacteria recorded in parallel at the same sampling point (26.5-fold reduction). During sham coronary angiography and sham hip arthroplasty performed in a room with six ACH, ultra-clean air (<10 CFU/m3) was obtained over the incision area with the TOUL-400 type 2 unit when the EUA was undisturbed (maximum screen-wound distance 1.7 m). In actual coronary angiography (room with six ACH, screen-wound distance 2.0-2.3m) and various surgical procedures in the OR (screen-wound distance 1.4-1.8m), ultra-clean air was obtained at the wound in three of 18 instances, characterized by undisturbed air flow and a maximum distance of 1.8 m. The newly developed TOUL-300 surgical instrument table (1.3-1.7 x 0.6m), equipped at one end with the same EUA unit as the TOUL-400 unit, was evaluated for a room with six ACH and an OR with 16 ACH. It yielded ultra-clean air at 0.8m (1.9 CFU/m3, 96% reduction, P=0.01) and reduced the deposition rate by >60% over most of the table surface.

    upfront costs of some measures can be prohibitive even when they eventually pay for themselves. But this can be overcome by mechanisms such as international financing of capital costs. For other measures, the costs are typically borne by a few while the benefits accrue to everybody. In such cases civil society and governments must get involved. Governments are starting to act. In February, the US, Canada, Sweden, Bangladesh, Ghana and Mexico launched the Climate and Clean Air Coalition to support implementation of measures like these. This coalition will hopefully expand and achieve rapid, widespread adoption of measures to cut black carbon and ozone. While the climate benefits will be substantial, it is important to note that these measures cannot substitute for cuts in carbon dioxide. Black carbon, ozone, carbon monoxide and methane stay in the atmosphere for a fairly short time - a few days for black carbon and about a decade for methane. They thus respond quickly to emissions changes and give us substantial leverage over near-term climate change. In contrast, carbon dioxide is very long-lived and so responds slowly to emissions changes. This means that cuts have little immediate impact, but it also means they must be made now to avoid disastrous changes later on. Controlling short-lived climate pollutants is thus an issue of fairness. Much as failure to reduce carbon dioxide emissions soon would condemn future generations to disastrous change, failure to reduce near-term climate change condemns those alive today to suffer worsening effects of the sort already seen. Some wonder if we really can do both. We can, and we must.

    Air cleaning techniques have been applied worldwide with the goal of improving indoor air quality. The effectiveness of applying these techniques varies widely, and pollutant removal efficiency is usually determined in controlled laboratory environments which may not be realized in practice. Some air cleaners are largely ineffective, and some produce harmful by-products. To summarize what is known regarding the effectiveness of fan-driven air cleaning technologies, a state-of-the-art review of the scientific literature was undertaken by a multidisciplinary panel of experts from Europe, North America, and Asia with expertise in air cleaning, aerosol science, medicine, chemistry and ventilation. The effects on health were not examined. Over 26,000 articles were identified in major literature databases; 400 were selected as being relevant based on their titles and abstracts by the first two authors, who further reduced the number of articles to 160 based on the full texts. These articles were reviewed by the panel using predefined inclusion criteria during their first meeting. Additions were also made by the panel. Of these, 133 articles were finally selected for detailed review. Each article was assessed independently by two members of the panel and then judged by the entire panel during a consensus meeting. During this process 59 articles were deemed conclusive and their results were used for final reporting at their second meeting. The conclusions are that: (1) None of the reviewed technologies was able to effectively remove all indoor pollutants and many were found to generate undesirable by-products during operation. (2) Particle filtration and sorption of gaseous pollutants were among the most effective air cleaning technologies, but there is insufficient information regarding long-term performance and proper maintenance. (3) The existing data make it difficult to extract information such as Clean Air Delivery Rate (CADR), which represents a common benchmark for

    This report provides an overview of the provisions of the Clean Air Act and its Amendments of 1990 that identify hazardous air pollutant (HAP) emissions and addresses their regulation by the US Environmental Protection Agency (EPA). It defines the major energy sector sources of these HAPs that would be affected by the regulations. Attention is focused on regulations that would cover coke oven emissions; chromium emission from industrial cooling towers and the electroplating process; HAP emissions from tank vessels, asbestos-related activities, organic solvent use, and ethylene oxide sterilization; and emissions of air toxics from municipal waste combustors. The possible implications of Title III regulations for the coal, natural gas, petroleum, uranium, and electric utility industries are examined. The report discusses five major databases of HAP emissions: (1) TRI (EPA`s Toxic Release Inventory); (2) PISCES (Power Plant Integrated Systems: Chemical Emissions Studies developed by the Electric Power Research Institute); (3) 1985 Emissions Inventory on volatile organic compounds (used for the National Acid Precipitation Assessment Program); (4) Particulate Matter Species Manual (EPA); and (5) Toxics Emission Inventory (National Aeronautics and Space Administration). It also offers information on emission control technologies for municipal waste combustors.

  20. A flight investigation of oscillating air forces: Equipment and technique

    NASA Technical Reports Server (NTRS)

    Reed, W. H., III

    1975-01-01

    The equipment and techniques are described which are to be used in a project aimed at measuring oscillating air forces and dynamic aeroelastic response of a swept wing airplane at high subsonic speeds. Electro-hydraulic inertia type shakers installed in the wing tips will excite various elastic airplane modes while the related oscillating chordwise pressures at two spanwise wing stations and the wing mode shapes are recorded on magnetic tape. The data reduction technique, following the principle of a wattmeter harmonic analyzer employed by Bratt, Wight, and Tilly, utilizes magnetic tape and high speed electronic multipliers to record directly the real and imaginary components of oscillatory data signals relative to a simple harmonic reference signal. Through an extension of this technique an automatic flight-flutter-test data analyzer is suggested in which vector plots of mechanical admittance or impedance would be plotted during the flight test.

  7. Evaluation of various activated carbons for air cleaning - Towards design of immune and sustainable buildings

    NASA Astrophysics Data System (ADS)

    There are increased demands for security, sustainability and indoor air quality in today's building design, construction, operation and maintenance. Installation of air cleaning systems can improve the indoor air quality by reducing the air pollution levels, and enhance the building security against sudden release of chemical and/or biological agents. At the same time, air cleaning techniques may reduce the building energy consumption by reducing the outdoor air supply rate, hence lowering the needs for conditioning of outdoor air. While the air filtration of particulate matter is well standardized, the standards against which the performance of air cleaning for gaseous contaminants is measured or classified are still under development. This study examined the performance of various granular activated carbons (GACs) for the removal of volatile organic compounds (VOCs) from mechanically ventilated buildings. Eight different GACs (three virgin and five impregnated) were tested against toluene using a dynamic test system. The virgin GACs showed better performance than impregnated ones, the percentage and the type of impregnation affected the removal efficiencies. Tests were also conducted with selected GACs against toluene, cyclohexane and ethyl acetate at relative humidity (RH) values of 30%, 50% and 70%. The effect of humidity was dependant on the VOC used. Both for toluene and cyclohexane, the removal efficiency decreased as RH increased. However, higher humidity showed a positive impact on the removal of ethyl acetate.

  8. Plants + soil/wetland microbes: Food crop systems that also clean air and water

    2011-02-01

    The limitations that will govern bioregenerative life support applications in space, especially volume and weight, make multi-purpose systems advantageous. This paper outlines two systems which utilize plants and associated microbial communities of root or growth medium to both produce food crops and clean air and water. Underlying these approaches are the large numbers and metabolic diversity of microbes associated with roots and found in either soil or other suitable growth media. Biogeochemical cycles have microbial links and the ability of microbes to metabolize virtually all trace gases, whether of technogenic or biogenic origin, has long been established. Wetland plants and the rootzone microbes of wetland soils/media also been extensively researched for their ability to purify wastewaters of a great number of potential water pollutants, from nutrients like N and P, to heavy metals and a range of complex industrial pollutants. There is a growing body of research on the ability of higher plants to purify air and water. Associated benefits of these approaches is that by utilizing natural ecological processes, the cleansing of air and water can be done with little or no energy inputs. Soil and rootzone microorganisms respond to changing pollutant types by an increase of the types of organisms with the capacity to use these compounds. Thus living systems have an adaptive capacity as long as the starting populations are sufficiently diverse. Tightly sealed environments, from office buildings to spacecraft, can have hundreds or even thousands of potential air pollutants, depending on the materials and equipment enclosed. Human waste products carry a plethora of microbes which are readily used in the process of converting its organic load to forms that can be utilized by green plants. Having endogenous means of responding to changing air and water quality conditions represents safety factors as these systems operate without the need for human intervention. We review

    Sterling Organics produces the analgesic paracetamol (acetaminophen) at its Dudley, England, plant. The wastewater from the batch process contains intermediates such as para-aminophenol (PAP) and byproducts such as thiosulfates, sulfites and sulfides. To stay ahead of increasingly strict environmental legislation, Sterling Organics installed a wet-air oxidation system at the Dudley facility in August 1992. The system is made by Zimpro Environmental Inc. (Rothschild, Wis.). Zimpro's wet-air oxidation system finds a way around the limitations of purely chemical or physical processes. In the process, compressed air at elevated temperature and pressure oxidizes the process intermediates and byproducts and removes the color from the wastewater.

    Population growth and the proliferation of roadways in Southern California have facilitated a glut of mobile air pollution sources (cars and trucks), resulting in substantial atmospheric pollution. Despite successful efforts over the past 40 years to reduce pollution, an alarming set of health effects attributable to air pollution have been described in Southern California. The Children’s Health Study indicates that reduced lung function growth, increased school absences, asthma exacerbation, and new-onset asthma are occurring at current levels of air pollution, with sizable economic consequences. We describe these findings and urge a more aggressive effort to reduce air pollution exposures to protect our children’s health. Lessons from this “case study” have national implications.

    Rogers, Everett M; Peterson, Jeffery C

    2008-10-01

    The authors investigate the process through which clean indoor air ordinances were considered in 10 communities in the southwestern United States and key factors that influenced diffusion and adoption. Clean indoor air ordinances, which ban smoking in public places, were adopted in approximately 1,409 U.S. communities from 1986 to April 2004. The authors gathered data from 10 communities in New Mexico and Texas by means of face-to-face interview, e-mail, and telephone interviews and by analyzing archival materials. Important influences on the adoption or rejection of clean indoor air ordinances were (a) personal experiences of policy champions, (b) local framing of the ordinance as a public health issue versus as an economic/ business or an individual rights issue, and (c) interpersonal networks connecting a community to previously adopting communities. The policies that were adopted ranged in comprehensiveness, with each community of study reinventing model policies obtained from other communities.

    2009-02-01

    Ultrasonic cleaning of a conveyor belt was studied by building a pilot-scale conveyor with an ultrasonic cleaning bath. A piece of the stainless steel conveyor belt was contaminated with meat-based soil and Listeria monocytogenes strains (V1, V3, and B9) and incubated for 72 h to allow bacteria to attach to the conveyor belt surfaces. The effect of ultrasound with a potassium hydroxide-based cleaning detergent was determined by using the cleaning bath at 45 and 50 degrees C for 30 s with and without ultrasound. The detachment of L. monocytogenes from the conveyor belt caused by the ultrasonic treatment was significantly greater at 45 degrees C (independent samples t test, P < 0.001) and at 50 degrees C (independent samples t test, P = 0.04) than without ultrasound. Ultrasonic cleaning efficiency was tested with different cleaning durations (10, 15, 20, and 30 s) and temperatures (30, 45, and 50 degrees C). The differences in the log reduction between cleaning treatments were analyzed by analysis of variance with Tamhane's T2 posthoc test using SPSS (Chicago, IL). The lengthening of the treatment time from 10 to 30 s did not significantly increase the detachment of L. monocytogenes (ANOVA 0.633). At 30 degrees C and at the longest time tested (30 s), the treatment reduced L. monocytogenes counts by only 2.68 log units. However, an increase in temperature from 30 to 50 degrees C improved the effect of the ultrasonic treatment significantly (P < 0.01). Ultrasonic cleaning for 10 s at 50 degrees C reduced L. monocytogenes counts by more than 5 log units. These results indicate that ultrasonic cleaning of a conveyor belt is effective even with short treatment times.

    This paper provides a review of current knowledge about the suitability of sorbent-based air cleaning for removing volatile organic compounds (VOCs) from the air in commercial buildings as needed to enable reductions in ventilation rates and associated energy savings. The fundamental principles of sorbent air cleaning are introduced, criteria are suggested for sorbent systems that can counteract indoor VOC concentration increases from reduced ventilation, major findings from research on sorbent performance for this application are summarized, novel sorbent technologies are described, and related priority research needs are identified. Major conclusions include: sorbent systems can remove a broad range of VOCs with moderate to high efficiency, sorbent technologies perform effectively when challenged with VOCs at the low concentrations present indoors, and there is a large uncertainty about the lifetime and associated costs of sorbent air cleaning systems when used in commercial buildings for indoor VOC control. Suggested priority research includes: experiments to determine sorbent system VOC removal efficiencies and lifetimes considering the broad range and low concentration of VOCs indoors; evaluations of in-situ regeneration of sorbents; and an updated analysis of the cost of sorbent air cleaning relative to the cost of ventilation.

  20. The California fuel cell partnership: an avenue to clean air

    NASA Astrophysics Data System (ADS)

    Lloyd, Alan C.

    The California Fuel Cell Partnership presently consists of eight private companies, two state agencies and a federal government representative that will attempt to demonstrate the feasibility of fuel cell cars and buses. California has attempted to advance the commercialization of zero-emission vehicles for much of the past decade to help the state reduce its high levels of air pollution. A special advisory panel convened by the California Air Resources Board concluded last year that fuel cell technology could meet the key requirements for automobiles. The successful commercialization of fuel cell vehicles would help to reduce the levels of ozone, fine particles and toxic air contaminants that pose health risks to California's population. This technology can also help to reduce carbon dioxide emissions. California regulations now encourage the development of zero and near-zero emission vehicle technologies, including fuel cells. The Fuel Cell Partnership will operate approximately 50 fuel cell cars and buses until the year 2003 in order to produce important information on the vehicles and fueling infrastructure needed to support them.

  14. Aerosol optical depth in clean marine and continental northeast Atlantic air

    The aerosol optical depth (AOD) and Ångström exponent for the period 2002-2004 is evaluated for clean marine and continentally influenced air masses over the northeast Atlantic region. Measurements were carried out at the Mace Head atmospheric research station on the west coast of Ireland using a precision filter radiometer which measures the aerosol optical depth at four wavelengths centered at 368, 412, 500, and 862 nm. The clean marine AOD at 500 nm is characterized by a mean value of 0.14 ± 0.06, exhibiting relatively small temporal variability. The Ångström exponent was less than 1 for the majority of cases, having an average value of 0.40 ± 0.29 in clean marine conditions. The latter is consistent with the presence of relatively large supermicron particles, such as sea salt dominating the marine aerosol size distribution. The Ångström exponent shows a distinct seasonal cycle in clean marine air, with maximum values being derived in the summer months and minimum values in the winter. In continental air masses, while the range and standard deviation of the AOD is larger than in clean marine conditions, the overall mean AOD (τ500 = 0.19 ± 0.12) is comparable with the clean marine AOD. The continental Ångström exponent is larger, having a mean value of 1.07 ± 0.32. This is attributed to a dominating accumulation mode in the presence of urban-industrial aerosol particles originating mainly from continental Europe. These results demonstrate how the natural marine AOD can rival polluted AOD over the northeast Atlantic region and highlight the importance of the natural marine aerosol contribution over oceans.

  16. Rationing health protection: a proposal to exempt nuisance dust from US Clean Air Act regulations.

    PubMed

    Centner, Terence J; Colson, Gregory

    2013-03-15

    The US House of Representative has passed a bill called the "Farm Dust Regulation Prevention Act" (Dust Act) that would exempt most types of particulate matter (PM) in rural areas from the air quality controls of the US Clean Air Act. The Dust Act would markedly change the country's air quality standards. An examination of the proposed provisions shows that they would exempt non-combustion PM pollutants from mining, smelting, petroleum production, and power generation from existing air quality standards. Persons downwind from pollutants generated in rural areas could be exposed to concentrations of carcinogenic heavy metals, asbestos, and benzene known to adversely affect their health and ecological resources. Existing federal air quality standards based on science would be replaced by a flexible standard that rations health protection.

  20. A Multilevel Test of Constrained Choices Theory: The Case of Tobacco Clean Air Restrictions.

    PubMed

    Vuolo, Mike; Kadowaki, Joy; Kelly, Brian C

    2016-09-01

    According to Bird and Rieker's sociology of constrained choices, decisions and priorities concerning health are shaped by the contexts-including policy, community, and work/family-in which they are formulated. While each level received attention in the original and subsequent research, we contend their constrained choices theory provides a powerful multilevel framework for modeling health outcomes. We apply this framework to tobacco clean air restrictions, combining a comprehensive database of tobacco policies with the National Longitudinal Survey of Youth 1997 from ages 19 to 31. Using multilevel panel models, we find that clean air policies lower the odds of past 30 day smoking and dependence while controlling for other policy-, city-, and individual-level constraints. We also find unique between- and within-person effects, as well as gender effects, for the constraint levied by smoking bans. We argue for the theory's broad applicability beyond commonly cited findings regarding gender and biological influences.

  1. Youth participation in a community campaign to pass a clean indoor air ordinance.

    2010-07-01

    Because of the harmful effects of secondhand smoke, communities are organizing to pass clean indoor air policies. With youth being considered one of the most vulnerable populations to this health hazard, it can be strategic to campaigns and beneficial to the youth's development to involve them in efforts to control this toxin. However, youth participation in health campaigns is limited because of barriers inherent in these initiatives. This article presents lessons learned from a qualitative case study on the youth involvement in a successful local clean indoor air campaign. Through the analysis of semistructured interviews with the adult members of the campaign, group interviews and questionnaire completion by the youth members of the campaign, and additional insight made possible by participant observation, recommendations are provided to engage and sustain youth involvement in local public health initiatives.

  2. Clean Air Act likely to remain unchanged until new Congress takes office in '83

    Political differences between the Senate's effort to fine-tune the Clean Air Act and the House effort to cut back regulations will probably delay reauthorization until next year. Politically vulnerable House members are aware of the jobs versus clean air issue in their debate. The more-modest Senate goals will make compromise difficult. The major issues are automobile emissions, non-attainment penalties, acid rain, and prevention of significant deterioration (PSD) requirements. Reforms at the Environmental Protection Agency will be minimal while Congress debates, although EPA will try to expedite the emission-trading and bubble concepts. The US-Canadian acid rain study is experiencing problems because of confused loyalties, but former chairman Robert Sugarman suggests the US should meet Canada's goal of reducing sulfur dioxide emissions 50% as insurance while continuing research efforts.

    In July 2003, New York State implemented the Clean Indoor Air Act (CIAA) to reduce exposure to environmental tobacco smoke (ETS). In this cross-sectional study, workers (n=168) completed an interview assessing ETS exposure and provided urine for cotinine analysis. Hospitality workers recruited after implementation of the CIAA had significant reductions in ETS exposure and urine cotinine, compared with those recruited before implementation. The New York State CIAA yielded measurable reductions in ETS exposure for hospitality workers.

    Heat exchanger apparatus for use with refrigeration cycle heating and cooling equipment is disclosed. In the preferred embodiment, it cooperates with and modifies refrigeration equipment including a compressor, an expansion valve, an evaporator coil and a closed loop for cycling refrigerant. This apparatus is a sealed container adapted to be placed in a well extending into artesian (Relatively heated or chilled) formations whereby the water of the formation stabilizes the temperature around the unit and enables heating and cooling. The sealed unit receives refrigerant from the top which flows along the sidewall at a reduced temperature, thereby condensing on the sidewall and trickling down the sidewall to collect in a sump at the bottom where the compressor pump picks up condensed refrigerant as a liquid and pumps it out of the artesian well to the connected refrigeration equipment.

    1982-01-01

    Unconstrained energy resource development in the Rocky Mountain west is likely to threaten the environment and the health and well-being of the people. Impacts may be associated with visibility degradation, toxic concentrations of gases, and deposition of acidic or toxic substances. Because the possible benefits of energy development in the region are very large, there is great concern that constraints imposed by air quality regulation may preclude the use of important resources or make unduly expensive energy produced from the region. The conflict between energy and clean air in the region is exacerbated by non-energy sources, such as copper smelters and urban areas, that already pose significant environmental threats. The hard policy question is not how to preserve clean air resources or how to develop energy but how to achieve and balance both goals. The effects and regulatory costs and benefits of air pollution control are discussed, and policy directions to protect air quality while pursuing energy development are presented.

    This study investigated the formation of secondary pollutants resulting from household product use in the presence of ozone. Experiments were conducted in a 50-m 3 chamber simulating a residential room. The chamber was operated at conditions relevant to US residences in polluted areas during warm-weather seasons: an air exchange rate of 1.0 h -1 and an inlet ozone concentration of approximately 120 ppb, when included. Three products were used in separate experiments. An orange oil-based degreaser and a pine oil-based general-purpose cleaner were used for surface cleaning applications. A plug-in scented-oil air freshener (AFR) was operated for several days. Cleaning products were applied realistically with quantities scaled to simulate residential use rates. Concentrations of organic gases and secondary organic aerosol from the terpene-containing consumer products were measured with and without ozone introduction. In the absence of reactive chemicals, the chamber ozone level was approximately 60 ppb. Ozone was substantially consumed following cleaning product use, mainly by homogeneous reaction. For the AFR, ozone consumption was weaker and heterogeneous reaction with sorbed AFR-constituent VOCs was of similar magnitude to homogeneous reaction with continuously emitted constituents. Formaldehyde generation resulted from product use with ozone present, increasing indoor levels by the order of 10 ppb. Cleaning product use in the presence of ozone generated substantial fine particle concentrations (more than 100 μg m -3) in some experiments. Ozone consumption and elevated hydroxyl radical concentrations persisted for 10-12 h following brief cleaning events, indicating that secondary pollutant production can persist for extended periods.

    Experiments were conducted to quantify emissions and concentrations of glycol ethers and terpenoids from cleaning product and air freshener use in a 50-m{sup 3} room ventilated at {approx}0.5 h{sup -1}. Five cleaning products were applied full-strength (FS); three were additionally used in dilute solution. FS application of pine-oil cleaner (POC) yielded 1-h concentrations of 10-1300 {micro}g m{sup -3} for individual terpenoids, including {alpha}-terpinene (90-120), d-limonene (1000-1100), terpinolene (900-1300), and {alpha}-terpineol (260-700). One-hour concentrations of 2-butoxyethanol and/or dlimonene were 300-6000 {micro}g m{sup -3} after FS use of other products. During FS application including rinsing with sponge and wiping with towels, fractional emissions (mass volatilized/dispensed) of 2-butoxyethanol and d-limonene were 50-100% with towels retained, {approx}25-50% when towels were removed after cleaning. Lower fractions (2-11%) resulted from dilute use. Fractional emissions of terpenes from FS use of POC were {approx}35-70% with towels retained, 20-50% with towels removed. During floor cleaning with dilute solution of POC, 7-12% of dispensed terpenes were emitted. Terpene alcohols were emitted at lower fractions: 7-30% (FS, towels retained), 2-9% (FS, towels removed), and 2-5% (dilute). During air-freshener use, d-limonene, dihydromyrcenol, linalool, linalyl acetate, and {beta}-citronellol were emitted at 35-180 mg d{sup -1} over three days while air concentrations averaged 30-160 {micro}g m{sup -3}.

  3. Some considerations on noise monitoring for air handling equipments

    2017-02-01

    The HVAC (Heating, Ventilating and Air Conditioning) beneficiaries are in particular annoyed by the noise generated from the radiant unit and the air circulating ducts, since they are located inside the rooms and buildings. The comparatively experimental results highlight the relations between the air flow, pressure, power-charging and the sound level. The measurements are carried out at different fan’s speeds, ranging the power-charge from 30-100% while the duct air flow is slowly adjusted from full open to full closed, between 0-500 Pa. Third-octave band analysis of random noise of the handling units is realized in an anechoic room, using the measurement procedures that agrees the requirements of the ISO 3744:2011 and ISO 5136:2010 standards. For an accurate design of the HVAC system, the designer needs to know not only the sound power of the radiant unit, but also from all of the air paths, since the sound travels along with the conditioned air. The experimental methodology used in the paper is of real interest for the HVAC manufacturers, in order to rate the sound level of their products and to improve the noise attenuation.

    SciTech Connect

    Benthul, H.R.

    1996-08-01

    The Clean Air Act ({open_quotes}CAA{close_quotes}) of 1990 was in many respects a major overhaul of the previous versions of the Clean Air Act although it retained most of the preexisting major programs such as the basic National Ambient Air Quality Standards ({open_quotes}NAAQS{close_quotes}) scheme, PSD, new source performance standards, regulation of toxic air pollutants, and the like. The 1990 Act strengthened the enforcement provisions of the Act by enhancing the enforcement powers of the Environmental Protection Agency ({open_quotes}EPA{close_quotes}) of {section}113. For example, the criminal enforcement provisions of {section}113 are expanded both in the range of punishment and in the kinds of activities which are subject to criminal enforcement. Moreover, the Act now contains a number of additional enforcement provisions in addition to those found in {section}113. The purpose of this paper is to discuss both the {section}113 provision and as well, identify those enforcement provisions found outside {section}113. The latter provisions will be taken up first and addressed by Titles of the Act. The discussion of specific sections and subsections of the CAA are necessarily brief and in the nature of highlighting of particular features; like the rest of the CAA, careful reading and analysis is a requirement for full understanding.

  7. A public health context for residual risk assessment and risk management under the clean air act.

    PubMed

    Charnley, G; Goldstein, B D

    1998-09-01

    The 1990 amendments to the Clean Air Act required the EPA to institute new pollution control technology requirements for industrial sources of air pollution. In part because agreement could not be reached on the best way for the EPA to determine whether any significant risks to human health will remain after the technology controls are in place, the amendments also created a Commission on Risk Assessment and Risk Management and gave the commission a broad mandate to review and make recommendations concerning risk assessment and risk management in federal regulatory programs. In its March 1997 final report to Congress and the administration, the commission recommended a tiered approach to assessing such residual risks. That approach included the idea that when decisions about managing residual risks are made, emissions should be evaluated in the context of other sources of air pollution. Evaluating risks in their larger contexts is consistent with what the commission called a public health approach to environmental risk management. This paper describes the public health approach and how it applies to evaluating residual risks under the Clean Air Act.

    HD-2 grease is deliberately applied to Shuttle Redesigned Solid Rocket Motor (RSRM) D6AC steel hardware parts as a temporary protective coating for storage and shipping. This HD-2 grease is the most common form of surface contamination on RSRM hardware and must be removed prior to subsequent surface treatment. Failure to achieve an acceptable level of cleanliness (HD-2 calcium grease removal) is a common cause of defect incidence. Common failures from ineffective cleaning include poor adhesion of surface coatings, reduced bond performance of structural adhesives, and failure to pass cleanliness inspection standards. The RSRM hardware is currently cleaned and refurbished using methyl chloroform (1,1,1-trichloroethane). This chlorinated solvent is mandated for elimination due to its ozone depleting characteristics. This report describes an experimental study of an aqueous cleaning system (which uses Brulin 815 GD) as a replacement for methyl chloroform. Evaluation of process control parameters for this cleaner are discussed as well as cleaning mechanisms for a spray-in-air process.

This report describes an experimental study of an aqueous cleaning system (which uses Brulin 815 GD) as a replacement for methyl chloroform. Evaluation of process control parameters for this cleaner are discussed as well as cleaning mechanisms for a spray-in-air process.

    Each new HEPA filter installation presents a different physical configuration based on the system requirements the available space and designer preference. Each different configuration can result in variations of air flow uniformity inside the filter housing across the filter banks. This paper will present the results of air flow uniformity testing for six different filter housing/ductwork configurations and discuss if any of the variations in air flow uniformity is attributable to the difference in the physical arrangements for the six cases.

    Chile relies upon imports to satisfy its needs for equipment for environmental control. Despite the lack of specific statistics that could provide precise information, environmental specialists evaluate the U.S. position as quite promising in terms of sales prospects. As far as current market share in domestic market it is estimated that U.S. products have 40% of the Chilean market. U.S. imports should grow at least 30%, at the same growth rate of the total market.

  15. The politics of markets: The acid rain control policy in the 1990 Clean Air Act amendments

    This thesis is a review and critique of the development of the acid rain control policy codified as Title IV of the Clean Air Act. The amendments include provisions to address acid rain-air pollution that has been transformed and transported over long distances. Title IV also embodies the first large scale adoption of market principles and economic incentives in the cause of environmental protection. The acid rain control amendments are being hailed as a break with past environmental protection practice and are being offered as a model for further regulatory reform. The thesis looks at the roots of the acid rain policy and considers the set of legal, social, and economic relations embedded in the policy which define the nature of its legal controls over pollution and its inverse, environmental quality. It explores whether the creation of the emissions allowance trading system changes the social relationships that prevailed under the pre-amended Clean Air Act. It responds to and rebuts the concerns of some critics that the policy represents an alienation of the public's right to clean air. A review of the acid rain policymaking process provides a recent and concrete example of the two central concerns inherent in public policy: the making of decisions that establish institutional arrangements, or structures, that both constrain and liberate individual action at the operational level; and the search for the boundary between autonomous behavior and collective decision making. The policy responds to regulatory reform recommendations concerned with improving the effectiveness, accountability, and cost-effectiveness of environmental protection. As a model for future policymaking, the policy goes beyond and encompasses more than the welfare economics ideal of static economic efficiency and the [open quotes]free market environmentalism[close quotes] emphasis on private property and common law.

    This report examines Some issues that would I affect the refining industry if the requirements for hazardous air pollutants set out in Title III of the Clean Air Act Amendments were to impede the market entrance of oxygenated fuels, as me; required by Title II. It describes the mandate for reformulated gasoline; considers gasoline characteristics in light of component shifts in refining; examines the supply of, demand for, and cost of various feedstocks and blendstocks; and identifies the emissions and atmospheric impacts that might result from the production and use of reformulated gasoline. Attention is focused on methanol and MTBE, two potential blendstocks that are also hazardous air pollutants, and on maximum achievable control technology standards, which might be applied to the stationary sources that produce them.

    The objective of this study is to estimate the prevalence of self-reported secondhand smoke (SHS) exposures and its association with respiratory symptoms in a sample of young adults residing in a state with a partial clean indoor air law. A cross-sectional telephone survey of Florida households and a single state University was conducted in 2005. Enrolled participants between 18 and 24 years of age completed a 15-20 min interview assessing past and current SHS exposure and current respiratory symptoms (n = 1858). Approximately 60% of the sample were female; nearly 70% were non-Hispanic white, 10% were non-Hispanic Black, and 11% were Hispanic. Over two-thirds reported completing at least some college; 23% reported smoking in the past month. Nearly two-thirds (64%) reported visiting a bar or nightclub which exposed them to SHS in the previous month; nearly half (46%) reported SHS exposure while riding in automobiles; 15% reported occupational SHS exposure; and nearly 9% reported living with at least one smoker. In multivariable models, personal smoking behavior, parental smoking history, and exposure to SHS in automobiles and in bars or nightclubs were significantly associated with increased reports of respiratory symptoms. Despite residing in a "clean" indoor air state, the majority of surveyed young adults continue to report exposure to SHS, especially in automobiles and in bars, and these exposures adversely impact respiratory health. All municipalities should pursue clean indoor air legislation which does not exempt bars and restaurants. Educational campaigns directed at reducing SHS exposure in motor vehicles also are needed.
