    Climate change is not only dangerous but also expensive. On the other hand, air pollution abatement measures are costly as well. Scientists of the Microeconomics Department investigated how air pollution abatement and cost efficiency can best be combined. (orig.)

  2. Measurements of environmental policy for air pollution abatement

    International Nuclear Information System (INIS)

    The first part of the study goes into the determination of efficient strategies for the reduction of air pollutants. The developed method is not only derived theoretically but is tested with the concrete example of emissions sources of a German state. The second part goes into the question what the government can do in order to attain that air pollution abatement measures recognized as being efficient will be put into practice. As market economy mechanisms have advantages over central state planning in the allocation of economic resources the question arises if not also for environmental protection market economy tools may contribute to an improvement of the efficiency of air pollution abatement. Therefore the suitability of different tools of environmental policy for the realization of efficient air pollution abatement is investigated and evaluated. This is again not done abstractly but with existing emission sources. (orig./HSCH). 32 figs., 12 tabs

    Deep street canyons are characterized by weak ventilation and recirculation of air. In such environment, the exposure to particulate matter and other air pollutants is enhanced, with a consequent worsening of both safety and health. The main solution adopted by the international community is aimed at the reduction of the emissions. In this theoretical study, we test a new solution: the removal of air pollutants close to their sources by a network of Air Pollution Abatement (APA) devices. The ...

    Deep street canyons are characterized by weak ventilation and recirculation of air. In such environment, the exposure to particulate matter and other air pollutants is enhanced, with a consequent worsening of both safety and health. The main solution adopted by the international community is aimed at the reduction of the emissions. In this theoretical study, we test a new solution: the removal of air pollutants close to their sources by a network of Air Pollution Abatement (APA) devices. The APA technology depletes gaseous and particulate air pollutants by a portable and low-consuming scrubbing system, that mimics the processes of wet and dry deposition. We estimate the potential pollutant abatement efficacy of a single absorber by Computational Fluid Dynamics (CFD) method. The presence of the scrubber effectively creates an additional sink at the bottom of the canyon, accelerating its cleaning process by up to 70%, when an almost perfect scrubber (90% efficiency) is simulated. The efficacy of absorber is not...

  5. Working Group 'Air pollution abatement' of the University of Stuttgart -ALS. Annual report 1990

    International Nuclear Information System (INIS)

    Despite considerable efforts for air pollution abatement - examples are here desulphurization and nitrogen removal in power and large combustion plants as well as catalytic converters for automobiles there are still many problems to solve. Many small and medium-size companies still have to reduce production-related pollutant emissions, traffic still is a major source of pollutants. Air pollution abatement in the new Federal states and other Eastern European countries is a particularly urgent task and reductions of CO2 emissions from energy production processes with fossil fuels are not least a great challenge. Apart from industry, legislation and administration especially science is called upon to find solutions to these problems. The university of Stuttgart takes up the challenge. Numerous institutes - 17 of 8 faculties -united in the working group ''air pollution abatement'' of the university of Stuttgart which carries out in interdisciplinary cooperation research work in the area of air pollution abatement. In this annual report activities of individual member states institutes in the area of air pollution abatement (fields of study, current research projects, cooperations and publications in 1991) as well as joint projects are presented.

  9. Air pollutants and energy pathways; Extending models for abatement strategies

    International Nuclear Information System (INIS)

    This study presents the development and applications of regional and local scale models for use in integrated assessment of air pollution effects in conjunction with large-scale models. A regional deposition model called DAIQUIRI (Deposition, AIr QUality and Integrated Regional Information) for integrated assessment purposes in Finland was constructed, and regional matrices for nitrogen oxides and ammonia were developed from the results of the regional air quality model of the FMI. DAIQUIRI produced similar estimates of deposition from Finnish sources as the original model, and long-term trends and the average level of deposition estimated with DAIQUIRI were found comparable with the monitored deposition levels and trends. For the mid-nineties situation, the regional nitrogen modeling resulted in 9 % to 19 % (depending on the region compared) larger estimates of areas with acidity critical load exceedances than when using European scale nitrogen deposition modeling. In this work, also a method for estimating the impacts of local NOx emissions on urban and sub-urban ozone levels was developed and tested. The study concentrated on representing the destruction of ozone by fresh NO emissions in urban areas for future use in integrated assessment modeling of ozone control strategies. Correlation coefficients between measured daytime ozone values in the study area were found to improve from 0.64 (correlation between urban and surrounding rural measurements) to 0.85, on the average. The average correlation between daytime large-scale model estimates and urban site measurements was found to improve from 0.37 to 0.58. In the study, also integrated assessment model applications were carried out at European, national and local levels. The synergies between control strategies for CO2 and acidification and ozone formation in the case of the UN/FCCC Kyoto protocol and the air quality targets of the EU were assessed with the help of coupled models.

    Experts tend to disagree about the economic effects of air pollution abatement measures. This book, which addresses also non-experts, explains the analytical background on the basis of available data. The authors conclude that there is a wide range of political options for achieving the goal of air pollution abatement. They differentiate between the various levels of discussion and show how misinterpretations of scientific results come about, thus making an important contribution to a discussion that is based on facts rather than emotions. [German] Die Einschaetzungen zur wirtschaftlichen Bewertung von Klimaschutzmassnahmen, insbesondere zur Steigerung der Energieeffizienz, sind sehr widerspruechlich. Dieses Buch erlaeutert anhand von Zahlenmaterial die analytischen Hintergruende und ist auch fuer Nicht-Oekonomen verstaendlich geschrieben. Die Autoren kommen zu dem Schluss, dass in vielen Bereichen rentable Energiesparpotentiale nicht erkannt und umgesetzt werden. Sie zeigen, dass die Politik bei der Verfolgung von Klimaschutzzielen und der Vorbeugung gegen Klimaschaeden ueber erheblichen Gestaltungsspielraum verfuegt. Mit der Entflechtung verschiedener Diskussionsebenen und dem Aufzeigen der Quellen fuer Fehlinterpretationen von Studienergebnissen leistet das Buch einen wichtigen Beitrag zur Versachlichung der Klimaschutzdiskussion.

  14. More electric power for cleaner air: ENEL air pollution abatement program

    International Nuclear Information System (INIS)

    ENEL (Italian National Electricity Board) is conducting an intensive anti-pollution campaign that is expected to lead to overall reductions by about 80% in polluting emissions by the year 2000. Existing plants are being equipped with low NOx burners and electrostatic precipitators; coal units are receiving flue gas desulfurization systems. New poly-fuel plants, to be located far from residential zones, are to use low sulfur fuels or natural gas, and employ 250 meter high smoke-stacks. ENEL's anti-pollution campaign also involves a series of co-ordinated research studies directed towards the development of new sulfur and nitrogen oxides emission control technologies and innovative fluidized-bed and coal-water fuel slurry combustion systems. ENEL will also participate with the Ministry of Agriculture and Forests in environmental protection programs. These will involve the setting-up of acid rain monitoring and sampling networks and atmospheric circulation mapping and modelling

  16. Practical ways to abate air and water pollution worldwide including a unique way to significantly curb global warming

    Energy Technology Data Exchange (ETDEWEB)

    Snell, J.R.

    1998-07-01

    This paper points out that in the next 50 years it will largely be the developing countries of the world which will continue to industrialize rapidly and hence pollute the water and air of not only their countries but that this pollution is becoming global (80% of the World's population.) From the author's 25 years of consulting experience in the developing countries, their greatest need is to have available to them low cost, innovative processes for pollution abatement will be neglected and the whole world will suffer immensely. The paper discusses in some detail the type of innovative low cost methods which have successfully been used in the categories of wastewater and solid wastes and names 6 other categories where many others exist. All these innovative methods need to be discovered, listed, and tested for quality and dependability, and then made widely available. Large Environmental Engineering Universities and International Consulting Engineering firms need to be organized to undertake these important tasks. The paper also points out the connection between Global Warming and the Solid waste industry and shows how it can be controlled inexpensively by employing a new, unique, and rapid method of converting municipal refuse into methane and then using that to make electricity. Information given in this paper could lead to a vast reduction in future pollution, with the resulting better global health and at the same time save trillions of dollars.

    The book intends to put the discussion of economic effects of air pollution abatement and energy efficiency increasing measures on a more rational basis. It addresses all parties taking part in the political discussion. ARguments are presented in a clear and transparent form that will also help the layman. The reader is enabled to interpret data and analyze them critically. A very important basis is the recognition of the various decision making patterns in which the cost and benefits of energy efficiency increasing patterns are key arguments. [German] Ziel der vorliegenden Argumentationshilfe ist es, die Diskussion um die wirtschaftlichen Auswirkungen von Klimaschutzmassnahmen, und insbesondere von energieeffizienzsteigernden Massnahmen, zu versachlichen und transparent zu machen. Sie richtet sich insbesondere an Politiker, aber auch an Vertreter von Wirtschaftsverbaenden und anderen Nicht-Regierungsorganisationen, die an dieser politischen Diskussion teilnehmen. Insofern wurde besonderes Gewicht auf eine einfache, klare und anschauliche Argumentation gelegt, die auch fuer betriebs- oder volkswirtschaftliche Laien verstaendlich ist. Die Argumentationshilfe versetzt den Leser in die Lage, die Zahlenangaben zur wirtschaftlichen Bewertung von Massnahmen zur Energieeinsparung zu interpretieren und ihre Herleitung kritisch zu bewerten. Eine erste wichtige Grundlage dafuer ist das Erkennen der verschiedenen Entscheidungszusammenhaenge, in denen mit Kosten und Nutzen von energieeffizienzsteigernden Massnahmen argumentiert wird. Nach einer kurzen Beschreibung und Abgrenzung dieser verschiedenen Argumentationsebenen im Ueberblick (Abschnitt 2) werden anschliessend fuer jede Ebene (Abschnitt 3 bis 5) die zentralen Einflussparameter aufgezeigt, die bestimmen, ob eine eher positive oder eher negative wirtschaftliche Bewertung von Massnahmen zur Steigerung der Energieeffizienz ausgewiesen wird und in welcher Groessenordnung sich die Werte bewegen.

    This paper investigates the effects of the transfer of pollution abatement technology on the level of urban unemployment, the total amount of pollution, and social welfare in a small, open Harris Todaro economy. We show that these transfers reduce urban unemployment and decrease the total amount of pollution. However, social welfare is unchanged because the technology transfer does not affect factor prices.

  5. Co-benefits of energy efficiency improvement and air pollution abatement in the Chinese iron and steel industry

    International Nuclear Information System (INIS)

    In 2010, China was responsible for 45% of global steel production, while consuming 15.8 EJ of final energy and emitting 1344 Mt CO2eq, 8.4 Mt of PM (particulate matter) emissions, and 5.3 Mt of SO2 emissions. In this paper we analyse the co-benefits of implementing energy efficiency measures that jointly reduce greenhouse gas emissions and air pollutants, in comparison to applying only air pollution control (end-of-pipe technology). For this purpose we construct ECSC (energy conservation supply curves) that contain potentials and costs of energy efficiency measures and implement these in the GAINS (greenhouse gas and air pollution interactions and synergies) model. Findings show that the technical energy saving potential for the Chinese iron and steel industry for 2030 is around 5.7 EJ. This is equivalent to 28% of reference energy use in 2030. The emissions mitigation of GHGs (greenhouse gases) and air pollutants in BAEEMS3 scenario would be reduce 27% CO2eq, 3% of PM, and 22% of SO2, compared to the BL scenario in 2030. Investments and cost savings were calculated for different scenarios, showing that energy efficiency investments will result in significant reductions in air pollution control costs. Hence, Energy efficiency measures should be integrated in air quality policy in China. - Highlights: • Implementation rates of 56 EEMs (energy efficiency measures) are quantified in China's Iron and steel industry. • Energy Supply Cost Curve was implemented in the GAINS (greenhouse gas and air pollution interactions and synergies) model. • The contribution of energy efficiency measure on the process level was estimated. • There are large co-benefits of improving energy efficiency and reducing emissions. • EEMs (energy efficiency measures) would lead to huge reductions in air pollution

    Highlights: • Implementation rates of 37 EEMs are quantified for China’s cement industry. • Energy Supply Cost Curves were implemented in the GAINS model. • The economic energy saving potential is 3.0 EJ and costs is $4.1 billion in 2030. • Energy efficiency would lead to large reductions in air pollution. • The co-benefits decrease average marginal costs of EEMs by 20%. - Abstract: China’s cement industry is the world’s largest and is one of the largest energy consuming, and GHG and air pollutant emitting industries. Actions to improve energy efficiency by best available technology can often bring co-benefits for climate change and air quality through reducing emissions of GHGs and air pollutants emission. In this study, the energy conservation supply curves (ECSC) combined with the GAINS (Greenhouse Gas and Air Pollution Interactions and Synergies) was used to estimate the co-benefits of energy savings on CO2 and air pollutants emission for implementing co-control options of energy efficiency measures and end-of-pipe options in the China’s cement industry for the period 2011–2030. Results show that there are large co-benefits of improving energy efficiency and reducing emissions of CO2 and air pollutants for the China’s cement industry during the study period. The cost-effective energy saving potential (EEP1 scenario) and its costs is estimated to be 3.0 EJ and 4.1 billion $ in 2030. The technical energy savings potential (EEP2 scenario) and its costs amount to 4.2 EJ and 8.4 billion $ at the same time. Compared to the baseline scenario, energy efficiency measures can help decrease 5% of CO2, 3% of PM, 15% of SO2, and 12% of NOx emissions by 2030 in EEP1 scenario. If we do not consider costs (EEP2 scenario), energy efficiency measures can further reduce 3% of CO2, 2% of PM, 10% of SO2, and 8% of NOx by 2030. Overall, the average marginal costs of energy efficiency measures will decrease by 20%, from 1.48 $/GJ to 1.19 $/GJ, when taking into

  11. Potential impact on air pollution from ambitious national CO2 emission abatement strategies in the Nordic countries – environmental links between the UNFCCC and the UNECE – CLRTAP

    International Nuclear Information System (INIS)

    This article presents results from a meta-study of Nordic low carbon dioxide (CO2) emission scenarios. The focus of the study was to explore possible environmental impacts if selected Nordic low CO2 emission scenarios were achieved by 2020. The impacts of concern were climate change, acidification, eutrophication and human health. Results from this study indicate that large scale reduction of CO2 emissions by 2020 in a Nordic energy system requires large scale penetration of technical measures and structural changes. The environmental improvements achieved would most often facilitate achievement of air pollution targets as well as post-Kyoto targets for greenhouse gas (GHG) emissions. All scenarios do, however, not imply co-benefits between air pollution and CO2 emission reductions and the net impact on climate change could be smaller than anticipated. A conclusion is that co-benefits and risks for trade-offs between air quality and climate change should be emphasised in the development of low-CO2 energy and emission strategies. - Highlights: ► CO2 abatement strategies differ in impact on environment, human health and climate. ► Bio fuel CO2 strategies can imply smaller climate and environmental benefits. ► Nordic ‘clean’ electricity export can give environmental benefits if replacing coal.

  14. Technico-economic evaluation of abatement systems applying to air pollution resulting from coal-fired power plants

    International Nuclear Information System (INIS)

    The aim of this study is to contribute to the analysis of the health care policies which could be considered in coal-fired power plants, in the comparative framework of the radiation protection in nuclear power plants. After a recall of the typical parameters of the air pollution due to the normal operation of a coal-fired power plant, we develop a heuristic model which allows, after having quantified the releases, to determine the theoretical health effects associated to a one-year operation of the power plant. The comparison of the various protection policies has been done with the help of a cost-effectiveness analysis. An examination of the results shows that the policy presently implemented forms a part of the cost-effective options. Nevertheless, it can be seen that the marginal protection cost is higher in nuclear power plants than in coal-fired power plants

    Quantitative impact of the recent abatement of air pollution on the weathering of stone and glass of the UNESCO List in Paris R.-A. Lefèvre1, A. Ionescu1, J. Desplat2, R. Kounkou-Arnaud2, O. Perrussel3, B. Languille4 At the beginning of the 21st century air pollution in Paris continued to considerably decrease. An evident visual consequence was the replacement of thick gypseous black crusts by thin grey coverings on the façades. A quantitative approach of this phenomenon was taken by measurement in the field, followed by calculation using Dose-Response Functions (DRF) and mapping the geographic distribution on a grid of 100m x100m of: 1) The total surface of façades of buildings and monuments in the part of Paris inscribed on the UNESCO List between the Ile Saint-Louis and the Concorde Square; 2) The surface of limestone and window glass present on each façade; 3) The distribution of SO2, NO2 and PM10 concentration every year from 1997 to 2014; 4) The response of materials to climatic and pollution doses; 5) The effective damage to limestone and window glass. Results of measurements in the field: 1) The 772 buildings and monuments inventoried have 20 674 m in length and 414 811 m2 in façade surface: they are representative of the centre of Paris; 2) Limestone occupies 348 268 m2 and window glass 207 394 m2; 3) The mean annual concentration in SO2 dropped from 20 to less than 3 μg m-3; NO2 from 60 to 40 μg m-3 and PM10 from 30 to 20 μg m-3. Results by application of DRF: 4) Limestone recession was divided by 5 in 18 years, from 10 to 2 μm y-1, but with only a spatial variation of 2%; 5) Limestone reflectance increased from 70.5 to 72.5 %; 6) The annual mass of deposited and neo-formed particles on window glass decreased from 100 to 20 μg cm-2; 7) The annual haze of window glass decreased from 8 to 3.5%.

    The impact of environmental innovation on the marginal pollution abatement cost at the firm level is investigated. We show that the common assumption that innovation reduces the marginal abatement cost is wrong. We draw some implications about the incentives to innovate under environmental regulation. In particular, we find that adopting an environmental friendly technology may lead to more pollution and less profit at the firm level.

  2. Air pollution

    International Nuclear Information System (INIS)

    Australian cites experience a number of current and emerging air pollution problems. Concentrations of traditional primary pollutants such as CO, lead and dust have fallen in recent years as a consequence of air pollutant control measures, and the widespread introduction of lead-free petrol. However, recommended guidelines for ozone, the principal component of photochemical smog, are regularly exceeded in major capital cities in the summer months. In addition, it is predicted that extensive urban expansion will lead to much greater dependence on the motor vehicle as the primary means of transportation. Effects of air pollution are felt at a variety of scales. Traditionally, concerns about gaseous and particulate emissions from industrial and vehicular sources were focused on local impacts due to exposure to toxic species such as CO and lead. As noted above, concentrations of these pollutants have been reduced by a variety of control measures. Pollutants which have effects at a regional scale, such as photochemically-produced ozone, and acidic gases and particles have proved more difficult to reduce. In general, these pollutants arc not the result of direct emissions to atmosphere, but result from complex secondary processes driven by photochemical reactions of species such as NO2 and aldehydes. In addition, global effects of gaseous and particulate emissions to the atmosphere have received significant recent attention, concentrations of atmospheric CO2 with predicted impacts on global climate, and ozone depletion due to anthropogenic emissions of chlorine-containing chemicals are the two major examples. Combustion processes from petrol- and diesel-fuelled vehicles, make major contributions to air pollution, and the magnitude of this contribution is discussed in this article

  3. Climate and air quality-driven scenarios of ozone and aerosol precursor abatement

    International Nuclear Information System (INIS)

    In addition to causing domestic and regional environmental effects, many air pollutants contribute to radiative forcing (RF) of the climate system. However, climate effects are not considered when cost-effective abatement targets for these pollutants are established, nor are they included in current international climate agreements. We construct air pollution abatement scenarios in 2030 which target cost-effective reductions in RF in the EU, USA, and China and compare these to abatement scenarios which instead target regional ozone effects and particulate matter concentrations. Our analysis covers emissions of PM (fine, black carbon and organic carbon), SO2, NOx, CH4, VOCs, and CO. We find that the effect synergies are strong for PM/BC, VOC, CO and CH4. While an air quality strategy targeted at reducing ozone will also reduce RF, this will not be the case for a strategy targeting particulate matter. Abatement in China dominates RF reduction, but there are cheap abatement options also available in the EU and USA. The justification for international cooperation on air quality issues is underlined when the co-benefits of reduced RF are considered. Some species, most importantly SO2, contribute a negative forcing on climate. We suggest that given current knowledge, NOx and SO2 should be ignored in RF-targeted abatement policies.

  6. Are the costs of pollution abatement lower in Central and Eastern Europe? Evidence from Lithuania

    International Nuclear Information System (INIS)

    It is often claimed that pollution reductions can be achieved at lower cost in Central and Eastern Europe and the former Soviet Union, because more possibilities exist to update production processes and reduce waste. To date, however, there has been little or no systematic evaluation of what the costs actually are in these countries. The main purpose of this paper is to partially fill this research gaps using firm-level data from Lithuania. Abatement cost estimates for key air pollutants are presented based on investments made in Lithuania during 1993-4. The paper also attempts to estimate the demand for pollution directly using data on pollution charges from 1994. Using both methods, it is shown that for at least some key pollutants marginal and average abatement costs are probably substantially lower in Lithuania than in western countries. (Author)

  7. Emissions leakage and subsidies for pollution abatement. Pay the polluter or the supplier of the remedy?

    Energy Technology Data Exchange (ETDEWEB)

    Asymmetric regulation of a global pollutant between countries can alter the competitiveness of industries and lead to emissions leakage. For most types of pollution, abatement technologies are available for firms to produce with lower emissions. However, the suppliers of those technologies tend to be less than perfectly competitive, particularly when both emissions regulations and advanced technologies are new. In this context of twin market failures, we consider the relative effects and desirability of subsidies for abatement technology. We find a more robust recommendation for upstream subsidies than for downstream subsidies. Downstream subsidies tend to increase global abatement technology prices, reduce pollution abatement abroad and increase emission leakage. On the contrary, upstream subsidies reduce abatement technology prices, and hence also emissions leakage.(Author)

  5. Prospects for non-thermal atmospheric plasmas for pollution abatement

    International Nuclear Information System (INIS)

    For approximately the past ten years, atmospheric pressure non-thermal plasmas have been increasingly promoted as a technology for a number of applications in the area of pollution abatement. In such plasmas, the electrons have a significantly higher temperature compared to the ions, atoms and molecules. This paper provides an overview of both the technologies involved and the diverse potential application areas. A general description of these atmospheric plasmas and the basic principles involved in the destruction or removal of gaseous phase pollutants, based on the nature of the processes taking place within these plasmas, are given. A number of examples of the different plasma technologies are described. The technologies described are pulsed corona, microwave and dielectric barrier plasmas. Their suitability and use in various application areas are also discussed including incinerator off gas treatment, industrial process off gas treatment and diesel exhaust aftertreatment. The use of modelling of the physical and chemical processes involved to predict system performance and as a tool for sizing systems to meet customer requirements is also discussed. (author)

Since a manual already exists for the computation of doses from radioactive air pollutants, a general approach is take here i.e. air pollutants in general are considered. The first chapter presents a brief introduction to the need and scope of air pollution dispersion modelling. The second chapter is a very important chapter discussing the aspects of meteorology relevant to air pollution and dispersion modelling. This chapter is important because without this information one really does not understand the phenomena affecting dispersion, the scope and applicability of various models or their limitations under various weather and site conditions. The third chapter discusses the air pollution models in detail. These models are applicable to distances of a few tens of kilometres. The fourth chapter discusses the various aspects of meteorological measurements relevant to air pollution. The chapters are followed by two appendices. Apendix A discusses the reliability of air pollution estimates. Apendix B gives some practical examples relevant to general air pollution. It is hoped that the document will prove very useful to the users. (author)

    International Nuclear Information System (INIS)

    Indoor air pollution is a potential risk to human health. Prolonged exposure to indoor pollutants may cause various infectious, allergic and other diseases. Indoor pollutants can emanate from a broad array of internal and external sources. Internal sources include building and furnishing materials, consumer and commercial products, office equipment, micro-organisms, pesticides and human occupants activities. External sources include soil, water supplies and outside makeup air. The main indoor air pollutants of concern are inorganic gases, formaldehyde and other volatile organic compounds, pesticides, radon and its daughters, particulates and microbes. The magnitude of human exposure to indoor pollutants can be estimated or predicted with the help of mathematical models which have been developed using the data from source emission testing and field monitoring of pollutants. In order to minimize human exposure to indoor pollutants, many countries have formulated guidelines / standards for the maximum permissible levels of main pollutants. Acceptable indoor air quality can be achieved by controlling indoor pollution sources and by effective ventilation system for removal of indoor pollutants. (author)

    International Nuclear Information System (INIS)

    Although official efforts to control air pollution have traditionally focused on outdoor air, it is now apparent that elevated contaminant concentrations are common inside some private and public buildings. Concerns about potential public health problems due to indoor air pollution are based on evidence that urban residents typically spend more than 90 percent of their time indoors, concentrations of some contaminants are higher indoors than outdoors, and for some pollutants personal exposures are not characterized adequately by outdoor measurements. Among the more important indoor contaminants associated with health or irritation effects are passive tobacco smoke, radon decay products, carbon monoxide, nitrogen dioxide, formaldehyde, asbestos fibers, microorganisms and aeroallergens. Efforts to assess health risks associated with indoor air pollution are limited by insufficient information about the number of people exposed, the pattern and severity of exposures, and the health consequences of exposures. An overall strategy should be developed to investigate indoor exposures, health effects, control options, and public policy alternatives

    Indoor air pollution after being a neglected subject for a number of years, is attracting attention recently because it is a side effect of energy crisis. About 50% of world's 6 billion population, mostly in developing countries, depend on biomass and coal in the form of wood, dung and crop residues for domestic energy because of poverty. These materials are burnt in simple stoves with incomplete combustion and infants, children and women are exposed to high levels of indoor air pollution for a considerable period, approximately between 2-4 hours daily. Current worldwide trade in wood fuel is over US $7 billion and about 2 million people are employed full time in production and marketing it. One of the most annoying and common indoor pollutant in both, developing and developed countries, is cigarette smoke. Children in gas-equipped homes had higher incidences of respiratory disease. Babies' DNA can be damaged even before they are born if their mothers breathe polluted air. Exposure to indoor air pollution may be responsible for nearly 2 million excess deaths in developing countries and for 4% of the global burden of the disease. Only a few indoor pollutants have been studied in detail. Indoor air pollution is a major health threat on which further research is needed to define the extent of the problem more precisely and to determine solutions by the policy-makers instead of neglecting it because sufferers mostly belong to Third World countries.

  3. Cost estimate of multi-pollutant abatement from the power sector in the Yangtze River Delta region of China

    International Nuclear Information System (INIS)

    Coal-fired power plants in China have emitted multiple pollutants including sulfur dioxide, nitrogen oxides and fine particulates, contributing to serious environmental impairments and human health issues. To meet ambient air quality standards, the installation of effective pollution control technologies are required and consequently, the cost of installing or retrofitting control technologies is an important economic and political concern. A multi-pollutant control cost model, CoST CE, is developed to calculate the cost of multi-pollutant control strategies in the Yangtze River Delta region (YRD) of China, adopting an LP algorithm to optimize the sorting of control technology costs and quickly obtain a solution. The output shows that total costs will increase along with emission abatement. Meanwhile, the slope becomes steeper as greater emission reductions are pursued, due to the need to install highly effective, but expensive, technologies like SCR and FF. Moreover, it is evident that the cost curve shapes, maximum abatement potential and total cost for the three provinces in the YRD region are quite different due to differences in power plant type and technologies, current emission levels and existing pollution controls. The results from this study can aid policy makers to develop cost-effective control strategies for the power sector

  6. Photochemical air pollution syndrome

    Energy Technology Data Exchange (ETDEWEB)

    Hamming, W.J.; MacBeth, W.C.; Chass, R.L.

    1967-01-01

    There are two distinct pollution problems in the Los Angeles Basin - one in winter, the other most frequently in summer and fall. In winter the concentrations of carbon monoxide, nitrogen oxides, sulfur dioxide and black filterable aerosols are higher than in summer, but the secondary pollutants such as ozone and photochemical oxidants are not as high. The photochemical air pollution syndrome is due to a pattern set by previous smog attacks. This pattern is due to low wind speeds, low inversion heights, a trajectory to carry the pollution and sufficient sunlight to photodissociate the nitrogen dioxide formed and to form nitric oxide and atomic oxygen. The results are high levels of oxidant or ozone and large quantities of particles. 5 references, 9 figures, 7 tables.

  7. Pollution abatement from road transport: cross-sectoral implications, climate co-benefits and behavioural change

    International Nuclear Information System (INIS)

    With the abatement potential of end-of-pipe technologies for road transport becoming increasingly marginal, and with greater emissions reductions still needed in order to reduce pollution, alternative strategies involving behavioural change and choices between fossil fuelled or low carbon vehicles becomes more important. The environmental requirements include local air quality objectives, meeting national emissions ceilings to limit transboundary effects, and to aspire to significant reductions in greenhouse gas emissions. In this paper we use the BRUTAL sub-model of the UK integrated Assessment Model (UKIAM) to investigate a selection of alternative strategies including downsizing of cars, switching from petrol to diesel, and the introduction of electric, bio-fuelled or hydrogen vehicles into the fleet, relative to a business-as-usual projection for 2020. Projected impacts upon air quality limit values, national emissions ceilings and CO2 emissions are assessed in relation to local, national and international objectives. We discuss related life-cycle impacts, implications for infrastructure, and potential impacts upon emissions from other sectors in order to highlight the full potential implications of the different strategies within the context of changes resulting from other policy developments at different scales.

  8. Privatization and the Environment in a Mixed Duopoly with Pollution Abatement

    OpenAIRE

    2009-01-01

    The purpose of this note is to re-examine whether privatization improves the environment or not in a mixed duopolistic model. In our model, both firms adopt pollution abatement technologies in response to the environmental tax imposed by the government. It is shown that privatization unambiguously reduces the pollution levels of firms. Namely, privatization does improve the environment. Moreover, by implementing partial-privatization policy, social welfare can be enhanced.

    This paper presents an incentive scheme to control agricultural non-point-source pollution. The analysis is based on a nested agent framework with three parties; farmers, a country's government, and the governments of all countries that affect each other's environmental quality. Unlike previous analysis of incentive schemes to control agricultural pollution, we suggest non-individual contracts between farmers and a regulating authority as a solution to the domestic pollution problem.

  12. THE USE OF ESTIMATED POLLUTION FLOWS IN AGRICULTURAL POLLUTION CONTROL POLICY: IMPLICATIONS FOR ABATEMENT AND POLICY INSTRUMENTS

    OpenAIRE

    1984-01-01

    Flows of water pollutants from agricultural sources are, for all practical purposes, unobservable by direct monitoring. These flows can, however, be estimated using hydrological models. The analysis presented in this paper demonstrates that uncertainty on estimated flows is not neutral with respect to the optimal level and allocation of estimated abatement or with respect to the expected net benefits of alternative pollution control policy instruments. Policy implications are noted.

  14. Considerations upon the possibility of abating the pollution produced by thermal power plants

    International Nuclear Information System (INIS)

    Thermal power plants using fossil fuels in conventional boilers are among the most important man-made stationary sources of pollutant release. A review of the present possibilities to abate the pollution, mainly by abatement of releases at stack is presented. At present the unique viable solution applicable in Romania thermopower stations appears to be the use of catalytic technology based on NOx selective reduction with ammonia. Investments for pollution abatement installations for intra- or post-combustion burning gases in classic boilers appear to be 1/4 and 1/3 of the cost of a new thermal power plant and the maintenance costs of de-pollution installations even when the resulting products are rendered profitable, the cost of KWh will raise. Replacement of classical boilers by circulating fluidized bed boilers would solve entirely the SO2 and NOx release issue. Investments for such boilers are lower than those implied by a new classical boiler equipped with supplementary installations for the removal of intra- and post-combustion gases. The only remaining drawback is waste resulting desulfurization which is disposed at the dump. (author)

  16. The timing of pollution abatement investments and the business cycle. An international comparison

    International Nuclear Information System (INIS)

    A simple equilibrium business-cycle model for an economy with both clean- and dirty-producing plants is developed. The authors derive that the optimal timing of cleaning the production process is during a slowdown of the economy. Due to external effects and market failures the timing of pollution abatement investments is not expected to be optimal in the real world. We test the optimality of the timing of those investments with data for Germany, the Netherlands and the U.S.A. It appears that for more than 25 percent of the sectors pollution abatement investments show counter-cyclical behaviour, while in only one sector these investments are pro-cyclical. 1 tab., 3 appendices, 10 refs

    International Nuclear Information System (INIS)

    In spite of improvements relative to air pollution, there is still much to do. more than thirty millions of European people are exposed to sulfur dioxide concentrations superior to guide values for health fixed by European Union, 20% of ecosystems in Europe are above the critical charges in the area of acidification and 33% concern eutrophication. Relative to the carbon dioxide, it is not sure that European Union realize the objective to stabilize the emissions for the year 2000 at the level of the year 1990, because of the increasing of automobile traffic and the energy consumption. Four subjects are presented: the climatic change, acidification and eutrophication, tropospheric ozone and air quality. (N.C.)

  19. A bottom-up method to develop pollution abatement cost curves for coal-fired utility boilers

    International Nuclear Information System (INIS)

    This paper illustrates a new method to create supply curves for pollution abatement using boiler-level data that explicitly accounts for technology cost and performance. The Coal Utility Environmental Cost (CUECost) model is used to estimate retrofit costs for five different NOx control configurations on a large subset of the existing coal-fired, utility-owned boilers in the US. The resultant data are used to create technology-specific marginal abatement cost curves (MACCs) and also serve as input to an integer linear program, which minimizes system-wide control costs by finding the optimal distribution of NOx controls across the modeled boilers under an emission constraint. The result is a single optimized MACC that accounts for detailed, boiler-specific information related to NOx retrofits. Because the resultant MACCs do not take into account regional differences in air-quality standards or pre-existing NOx controls, the results should not be interpreted as a policy prescription. The general method as well as NOx-specific results presented here should be of significant value to modelers and policy analysts who must estimate the costs of pollution reduction.

    This sixth volume of the series of Air Pollution Studies published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains the documents reviewed and approved for publication at the seventh session of the Executive Body held at Geneva from 21 to 24 November 1989. Part one is the annual review of strategies and policies for air pollution abatement. Country by country, recent legislative and regulatory developments are summarized, including ambient-air quality standards, fuel-quality standards, emission standards, as well as economic instruments for air pollution abatement. Part two is an executive summary of the 1988 forest damage survey in Europe, carried out under the International Co-operative Programme for Assessment and Monitoring of Air Pollution Effects on Forests which was established by the Executive Body for the Convention in 1985. A total of 25 countries participated in the survey, conducted in accordance with common guidelines laid down in an ECE manual on methodologies and criteria for harmonized sampling, assessment, monitoring and analysis of the effects of air pollution on forests. Parts three and four describe the effects of mercury and some other heavy metals related to the long-range atmospheric transport of pollution. The section on mercury describes the environmental effects and the causes of mercury pollution in air and atmospheric deposition, including its sources and its transport from forest soils into fresh water and aquatic organisms. The section dealing with other heavy metals (such as asbestos, cadmium and lead) describes the process of atmospheric transport and deposition, the effects on forest ecosystems, ground water, surface water and agricultural products.

    Coastal aquatic ecosystems are increasingly affected by diffuse source nutrient water pollution from agricultural activities in coastal catchments, even though these ecosystems are important from a social, environmental and economic perspective. To warrant sustainable economic development of coastal regions, we need to balance marginal costs from coastal catchment water pollution abatement and associated marginal benefits from coastal resource appreciation. Diffuse-source water pollution abatement costs across agricultural sectors are not easily determined given the spatial heterogeneity in biophysical and agro-ecological conditions as well as the available range of best agricultural practices (BAPs) for water quality improvement. We demonstrate how the Soil and Water Assessment Tool (SWAT) can be used to estimate diffuse-source water pollution abatement cost functions across agricultural land use categories based on a stepwise adoption of identified BAPs for water quality improvement and corresponding SWAT-based estimates for agricultural production, agricultural incomes, and water pollution deliveries. Results for the case of dissolved inorganic nitrogen (DIN) surface water pollution by the key agricultural land use categories ("annual crops," "vineyards," and "mixed annual crops & vineyards") in the Vouga catchment in central Portugal show that no win-win agricultural practices are available within the assessed BAPs for DIN water quality improvement. Estimated abatement costs increase quadratically in the rate of water pollution abatement, with largest abatement costs for the "mixed annual crops & vineyards" land use category (between 41,900 and 51,900 € tDIN yr) and fairly similar abatement costs across the "vineyards" and "annual crops" land use categories (between 7300 and 15,200 € tDIN yr).

    Full Text Available The increase of air pollution over the years has major effects on the human skin. The skin is exposed to ultraviolet radiation (UVR and environmental air pollutants such as polycyclic aromatic hydrocarbons (PAHs, volatile organic compounds (VOCs, oxides, particulate matter (PM, ozone (O3 and cigarette smoke. Although human skin acts as a biological shield against pro-oxidative chemical and physical air pollutants, the prolonged or repetitive exposure to high levels of these pollutants may have profound negative effects on the skin. Exposure of the skin to air pollutants has been associated with skin aging and inflammatory or allergic skin conditions such as atopic dermatitis, eczema, psoriasis or acne, while skin cancer is among the most serious effects. On the other hand, some air pollutants (ie, ozone, nitrogen dioxide, and sulfur dioxide and scattering particulates (clouds and soot in the troposphere reduce the effects of shorter wavelength UVR and significant reductions in UV irradiance have been observed in polluted urban areas.

    This paper examines the effects on human health and controlling measures of air pollution in Sri Lanka. The objectives of the study were to identify and categorize the major air pollutants in Sri Lanka and their sources; examine the public health effects of air pollution; study the air pollution situation in Sri Lanka; understand the link between respiratory illnesses in Sri Lanka and air pollution; and, find control measures taken by the regulatory authorities to abate air pollution. Data were collected through interviews and conversation with air pollution stakeholders, reference materials, and visits with the Central Environmental Authority, Urban Development Authority and Public Health Bureau. The paper concludes that automobile exhaust is one of the major causes of air pollution and that respiratory diseases in Sri Lanka have become a major health problem. The author recommends that control measures should be strengthened to abate air pollution in Sri Lanka; steps should be taken to minimize traffic congestion and to develop programs to raise public awareness; artificial materials such as polythene and plastics in day-to-day activities should be minimized; and recycling processes of artificial materials should be enhanced. 7 refs., 4 tabs., 2 figs.

    To assess the recovery rate of meiofaunal and nematode communities upon abatement of sewage pollution,a field transplantation experiment was conducted in Tai Tam,which is a non-polluted,shallow subtidal habitat on the southern portion of Hong Kong Island.The sediments used were from one site located in Victoria Harbour that was heavily influenced by sewage pollution,and one site in the outside-harbor area,which was relatively clean.In addition,sediments from Tai Tam were used as a control.Fresh sediments with meiofauna were collected from the aforementioned sites,placed in plastic trays and transplanted to Tai Tam.Sediments were retrieved at the beginning of the experiment and at 1-,3-,and 8-weeks after transplantation for analysis of the meiofaunal and nematode communities as well as the sediment characteristics.The results showed that the meiofaunal and nematode communities in the control sediments were consistent at the four sampling periods,while it took three and eight weeks,respectively,for the nematode communities from the outside-harbor and inside-harbor sites to become similar to the control.These findings indicated that the relatively poor habitat quality and the nematode community composition in the sewage polluted inside-harbor sediments required a longer time for recovery than samples from the better habitat quality and the nematode community composition in the outside-harbor sediments.

    2006-12-20

    Our central health cost estimate from particulate matter (PM) concentrations in larger Peruvian cities is approximately USD 790 million/year. More than 60 percent of these costs occur in Lima-Callao. Diesel vehicles are the most important emission source. Various abatement actions could yield health benefits of around USD 50 million in 2008 and USD 185 million after 2010. Some of the most important cost effective actions would be an inspection and maintenance (I&M) program for vehicles (planned to start in 2006) and introduction of low sulphur diesel (<50 ppm) from 2010. When low sulphur diesel is available, installing retrofit particle control technology on existing vehicles could be very cost effective. Some actions towards stationary sources could also be cost effective. In addition a mixture of several measures like tax incentives to promote use of gasoline cars at the expense of diesel cars, accelerated scrapping of old, polluting vehicles, ban on the use of some diesel vehicles and import restrictions on used cars could be chosen to yield short and long term air pollution benefits.

  17. ARAMIS a regional air quality model for air pollution management: evaluation and validation

    International Nuclear Information System (INIS)

    The aim of this research was to better understand the dynamics of air pollutants and to forecast the air quality over regional areas in order to develop emission abatement strategies for air pollution and adverse health effects. To accomplish this objective, we developed and applied a high resolution Eulerian system named ARAMIS (A Regional Air Quality Modelling Integrated System) over the north-east of Spain (Catalonia), where several pollutants exceed threshold values for the protection of human health. The results indicate that the model reproduced reasonably well observed concentrations, as statistical values fell within Environmental Protection Agency (EPA) recommendations and European (EU) regulations. Nevertheless, some hourly O3 exceedances in summer and hourly peaks of NO2 in winter were underestimated. Concerning PM10 concentrations less accurate model levels were obtained with a moderate trend towards underestimation during the day. (Author)

    1987-03-13

    In the discussion on possible adverse effects of air pollution upon human health one has to distinguish between out-door and in-door environment. The most frequent pollutants in out-door air over industrialized areas are particulate substances, sulfur dioxide, nitrous oxide, carbonmonoxide, ozone and lead. Most of these substances have direct irritating effects on mucous surfaces. Hypersensitivity reactions have been described against sulfur dioxide and sulfites occurring as asthma, urticaria or anaphylactoid reactions. In-door air pollution is of much greater practical importance for a variety of diseases. Apart from physio-chemical irritants and microbial organisms leading to infections, organic allergens (e.g. house dust mites, moulds, animal epithelia) can induce a variety of allergic diseases via different pathomechanisms.

  3. Geostatistical models for air pollution

    International Nuclear Information System (INIS)

    The objective of this paper is to present geostatistical models applied to the spatial characterisation of air pollution phenomena. A concise presentation of the geostatistical methodologies is illustrated with practical examples. The case study was conducted in an underground copper-mine located on the southern of Portugal, where a biomonitoring program using lichens has been implemented. Given the characteristics of lichens as indicators of air pollution it was possible to gather a great amount of data in space, which enabled the development and application of geostatistical methodologies. The advantages of using geostatistical models compared with deterministic models, as environmental control tools, are highlighted. (author)

    This paper discusses problems of air pollution control, air pollution abatement and effects of air pollution. Air pollution caused by black and brown coal combustion, by fossil-fuel power plants and by coking plants is evaluated. Air pollution by dusts, sulfur oxides, nitrogen oxides, carbon monoxide, ammonia as well arsenic, barium, beryllium, boron, chromium, gallium, cobalt, manganese, copper, nickel, lead, plutonium, titanium and vanadium, which sometimes accompany ashes in coal, is analyzed. Methods of air pollution abatement such as fluidized bed combustion, coal preparation, desulfurization or dry coke quenching are described. Systems for air pollution control are presented: air filtration, cyclones, electrostatic precipitators. Systems of air pollution measurement and recording are evaluated. Propagation of air pollutants in the atmosphere as well as the factors which influence pollutant propagation are characterized. Problems associated with site selection for fossil-fuel power plants are also discussed. An analysis of economic aspects of air pollution abatement and air pollution control is made. (55 refs.)

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

  9. Air pollution in Copenhagen

    International Nuclear Information System (INIS)

    Aerosols were monitored in Greater Copenhagen in the period June 1973 to July 1974. Size-fractionated cascade impactor samples and unfractionated filter samples were regularly collected and analyzed be neutron activation analysis, spark emission spectroscopy or proton-induced X-ray emission spectroscopy. Concentrations were determined of the following elements: Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Mo, Cd, Sn, Sb, and Pb. All elements showed orders-of-magnitude fluctuationsthe mean concentrations were roughly the same as in other large cities. In relation to proposed air quality standards, Pb was the most critical component. Statistical analysis of variation patterns, size distributions and interelement correlations indicate that automotive exhaust is the source of Br and Pbfuel-oil combustion is the main source of V and Ni (and partly of S)soil dust raised by wind or by human activity (e.g. traffic) is the main source of Al, Si, Ca, Ti, and Fe.

    The air pollution problem can be depicted as a system consisting of several basic components: source, concentration, exposure, dose, and adverse effects. Exposure, the contact between an agent (e.g., an air pollutant) and a target (e.g., a human respiratory tract), is the key to linking the pollution source and health effects. Human exposure to air pollutants depends on exposure concentration and exposure duration. Exposure concentration is the concentration of a pollutant at a contact bounda...

  17. Air pollution policy in Europe: Quantifying the interaction with greenhouse gases and climate change policies

    International Nuclear Information System (INIS)

    This paper uses the computable general equilibrium model WorldScan to analyse interactions between EU's air pollution and climate change policies. Covering the entire world and seven EU countries, WorldScan simulates economic growth in a neo-classical recursive dynamic framework, including emissions and abatement of greenhouse gases (CO2, N2O and CH4) and air pollutants (SO2, NOx, NH3 and PM2.5). Abatement includes the possibility of using end-of-pipe control options that remove pollutants without affecting the emission-producing activity itself. This paper analyses several variants of EU's air pollution policies for the year 2020. Air pollution policy will depend on end-of-pipe controls for not more than two thirds, thus also at least one third of the required emission reduction will come from changes in the use of energy through efficiency improvements, fuel switching and other structural changes in the economy. Greenhouse gas emissions thereby decrease, which renders climate change policies less costly. Our results show that carbon prices will fall, and may even drop to zero when the EU agrees on a more stringent air pollution policy. - Highlights: • This paper models bottom-up emission control in top-down CGE model. • We analyse interactions between air pollution and climate policies in Europe. • Structural changes induced by stringent air policies may make EU-ETS market obsolete

    2012-12-01

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

  19. Biomonitoring air pollution in Chile

    International Nuclear Information System (INIS)

    Full text: Chile, in general, and Santiago, its capital city, in particular, has serious air pollution problems mainly in winter time when the pollutants could reach dangerous levels which might be detrimental to older people and children. A project was undertaken within the framework of a Co-ordinated Research Programme (CRP) supported by the International Atomic Energy Agency (IAEA) to carry out a long term study on atmospheric air pollution in Chile using biomonitors. The present paper describes the activities carried out within this CRP. The lichens, collected in clean areas (native forests), were transplanted to selected sites in Santiago and exposed during three and six months. At a second stage, samples of Tillandsia recurvata were collected in the Metropolitan Area. All samples were carefully cleaned, using only clean plastic materials, milled at liquid nitrogen temperature, freeze dried, re-homogenized and stored at low temperature until analysis. The samples were mainly analysed by INAA, RNAA SS-AAS and ASV. As part of the routine QA/QC programme, analytical laboratories involved in the project participated in intercomparison runs organized by the IAEA for the determination of trace and minor elements in two lichens samples. From the data and its subsequent mapping over the area under study, it was possible to identify places exposed to higher amounts of some elements. Of interest are also the correlations between several elements, perhaps indicating a given source of pollutants. The results indicate the usefulness of biomonitoring air pollution using lichens and Tillandsias, which, jointly with multielemental analytical techniques, such as NAA, open the possibility to study extensive areas without the infrastructure needed for conventional APM sample collection and at reduced costs.

  6. Integrated systems for forecasting urban meteorology, air pollution and population exposure

    Directory of Open Access Journals (Sweden)

    A. Baklanov

    2007-01-01

    Full Text Available Urban air pollution is associated with significant adverse health effects. Model-based abatement strategies are required and developed for the growing urban populations. In the initial development stage, these are focussed on exceedances of air quality standards caused by high short-term pollutant concentrations. Prediction of health effects and implementation of urban air quality information and abatement systems require accurate forecasting of air pollution episodes and population exposure, including modelling of emissions, meteorology, atmospheric dispersion and chemical reaction of pollutants, population mobility, and indoor-outdoor relationship of the pollutants. In the past, these different areas have been treated separately by different models and even institutions. Progress in computer resources and ensuing improvements in numerical weather prediction, air chemistry, and exposure modelling recently allow a unification and integration of the disjunctive models and approaches. The current work presents a novel approach that integrates the latest developments in meteorological, air quality, and population exposure modelling into Urban Air Quality Information and Forecasting Systems (UAQIFS in the context of the European Union FUMAPEX project. The suggested integrated strategy is demonstrated for examples of the systems in three Nordic cities: Helsinki and Oslo for assessment and forecasting of urban air pollution and Copenhagen for urban emergency preparedness.

The review also presents legislative controls with judicial response to certain landmark judgments related to air pollution. The down sides related to enforcement mechanism for the effective implementation of environmental laws for air pollution control have been highlighted.

  12. Air pollution policies in Europe: efficiency gains from integrating climate effects with damage costs to health and crops

    International Nuclear Information System (INIS)

    Emissions of air pollutants cause damage to health and crops, but several air pollutants also have an effect on climate through radiative forcing. We investigate efficiency gains achieved by integrating climate impacts of air pollutants into air quality strategies for the EU region. The pollutants included in this study are SO2, NH3, VOC, CO, NOx, black carbon, organic carbon, PM2.5, and CH4. We illustrate the relative importance of climate change effects compared to damage to health and crops, as well as monetary gains of including climate change contributions. The analysis considers marginal abatement costs and compares air quality and climate damage in Euros. We optimize abatement policies with respect to both climate and health impacts, which imply implementing all measures that yield a net benefit. The efficiency gains of the integrated policy are in the order of 2.5 billion Euros, compared to optimal abatement based on health and crop damage only, justifying increased abatement efforts of close to 50%. Climate effect of methane is the single most important factor. If climate change is considered on a 20- instead of a 100-year time-scale, the efficiency gain almost doubles. Our results indicate that air pollution policies should be supplemented with climate damage considerations.

    Full Text Available Raising of problem. Any manufacturing processes related to the generation of waste. Year after year, a growing mass of waste is one of the main factors reducing the quality of the environment and destruction of natural landscapes. Industrial development inevitably enhances human impacts on the environment and disrupts the ecological balance [3]. Atmospher air is a vital element of the environment. The development of industry, the growth of cities, increasing the number of transport, active exploration of near-Earth space lead to a change in the gas composition of the atmosphere and disruption of its natural balance. Air quality affects the health of the population [5]. Without water or food a person can do for a while, but without air he can not live a few minutes, therefore saving air breathable is an urgent problem. Purpose. The results of geological studies clearly indicate that the contamination of the surface layer of the atmosphere is the most powerful permanent factor of influence on the human food chain and the environment. This problem was reflected in the scientific literature [2; 3; 6], and the second significant indicator of ecological well-being of the region is the number of generation and accumulation of waste. According to this indicator, Dnipropetrovsk region is in the lead, as relates to the industrialized regions. The idea of the article is to consider the air pollution of the urban environment in terms of the accumulation of waste in the territory of enterprises, in particular slag dumps metallurgical production. Conclusion. Slag dumps located on the premises are a significant source of air pollution urbanized areas due to the permanent nature of the spread of contamination. Slag dump of PAT "Nikopol Ferroalloy Plant" is a source of manganese, zinc, nickel emissions. As a conclusion about the magnitude of pollution of the atmospheric boundary layer can say the following: on the border of the sanitary protection zone (SPZ, in

    Direct biological monitoring of air pollution was introduced about 30 years ago. Although still under development, the application of biological monitors, or indicators, may provide important information on the levels, availability, and pathways of a variety of pollutants including heavy metals and other toxic trace elements in the air. A survey is given of the most frequently used biomonitors, such as herbaceous plants, tree leaves or needles, bryophytes, and lichens, with their possible advantages and/or limitations. In addition to using naturally-occurring biomonitors, a possibility of employing ''transplanted'' species in the study areas, for instance grasses grown in special containers in standard soils or lichens transplanted with their natural substrate to an exposition site, is also mentioned. Several sampling and washing procedures are reported. The important of employing nuclear analytical methods, especially instrumental neutron activation analysis, for multielemental analysis of biomonitors as a pre-requisite for unlocking the information contained in chemical composition of monitor's tissues, such as apportionment of emission sources using multivariate statistical procedures, is also outlined.

    Full Text Available The traffic is growing at rapid rate in urban areas of India and the management of traffic operations on the limited road network of the cities has become a gigantic task to the concerned authorities. Despite the concerted efforts of concerned authorities aimed at augmenting road infrastructure, traffic congestion is continuing to increase leading to environmental degradation. Eventually, a major study was commissioned by the Government of India to quantify urban travel by road and associated air pollutants coming from automobile exhausts in eight cities namely, Delhi, Mumbai, Kolkata, Chennai, Bangalore, Hyderabad, Kanpur and Agra. The main objective was to make an accurate assessment of total number of vehicles and develop database and techniques to estimate road traffic and pollution loads in each city. This paper describes operating characteristics of traffic and quantification of traffic and air pollution loads (base and horizon year on major road network of Chennai city. Comparatively urbanization is moderate in India. This is because the major contributor to the Indian economy is agriculture and it is rural based. As per the Census of India 2001, the urban population of India is around 28 percent of the total population. This proportion of urban population has grown from ten percent in 1901 to twenty eight percent in 2001. The disturbing aspect of the urbanization trends in India is the skewed distribution of the urban population. Nearly seventy percent of the urban population is located in Class-I cities (i.e. population of 100 Thousand and above. Further, 38 percent of the total urban population is located in metropolitan cities (i.e. population of 1 million and above numbering about thirty-five. This heavy concentration of population in a few centers has resulted in the expansion of cities in density as well as area.

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

    In this paper a cost-effectiveness of gaseous vehicular emission reduction has been carried out for human mobility, over the transport network in Rome: in other words, once a reduction target of total emissions has been fixed for each pollutant, the most efficient abatement measures from a technical-economic point of view are selected. The optimization problem has been formalized considering linear functions both for the objective function and for constrains, i.e. within the classic linear programming framework, the objective being that of finding the diversion of present vehicular traffic to alternative technologies with lower emissions at minimum costs. A set of transport alternative measures has been considered and emission abatement cost minimization has been assumed as an objective function; specified abatements for CO (Carbon monoxide), NO{sub x} (nitrogen oxides) and VOC (Volatile Organic Compounds) emissions have been introduced as constraints to the problem, expressed as reduction rates of estimated present emissions in the considered area. Model results show the distribution of present transportation capacity among possible alternatives for different hypothesis of emission reduction rates (reduction of 25%, 50%, 75%, 85% of present emissions and maximum feasible reduction within the specified constraints), and related costs. [Italian] In questo rapporto e' stata condotta un'analisi costi-efficacia relativa alla riduzione delle emissioni gassose veicolari dovute alla mobilita' urbana sulla rete di trasporto di Roma: in altre parole, fissata una quota di abbattimento delle emissioni complessive per ogni inquinante, sono state individuate le misure piu' efficienti dal punto di vista tecnico-economico che permettono di perseguire la riduzione prefissata. Il problema di ottimizzazione e' stato formalizzato definendo sia la funzione obiettivo che i relativi vincoli come funzioni lineari, e quindi nell'ambito della programmazione

    2011-08-01

    Managing urban air pollution necessitates a feasible and efficient abatement strategy which is characterised as a defined set of specific control measures. In practice, hard budget constraints are present in any decision-making process and therefore available alternatives need to be hierarchised in a fast but still reliable manner. Moreover, realistic strategies require adequate information on the available control measures, taking also into account the area's special characteristics. The selection of the most applicable bundle of measures rests in achieving stakeholders' consensus, while taking into consideration mutually conflicting views and criteria. A preliminary qualitative comparison of alternative control measures would be most handy for decision-makers, forming the grounds for an in-depth analysis of the most promising ones. This paper presents an easy-to-follow multicriteria methodological approach in order to include and synthesise multi-disciplinary knowledge from various stakeholders so as to result into a priority list of abatement options, achieve consensus and secure the adoption of the resulting optimal solution. The approach relies on the active involvement of public authorities and local stakeholders in order to incorporate their environmental, economic and social preferences. The methodological scheme is implemented for the case of Thessaloniki, Greece, an area considered among the most polluted cities within Europe, especially with respect to airborne particles. Intense police control, natural gas penetration in buildings and metro construction equally result into the most "promising" alternatives in order to control air pollution in the GTA. The three optimal alternatives belong to different thematic areas, namely road transport, thermal heating and infrastructure. Thus, it is obvious that efforts should spread throughout all thematic areas. Natural gas penetration in industrial units, intense monitoring of environmental standards and regular

    A bioaquatic air pollution control system for controlling both water and atmospheric pollution is disclosed. The pollution control system includes an exhaust for directing polluted gases out of a furnace and a fluid circulating system which circulates fluid, such as waste water, from a source, past the furnace where the fluid flow entrains the pollutants from the furnace. The combined fluid and pollutants are then directed through a rock/plant/microbial filtering system. A suction pump pumps the treated waste water from the filter system past the exhaust to again entrain more pollutants from the furnace where they are combined with the fluid (waste water) and directed to the filter system.

  15. Benefits of European Climate Policies for Mercury Air Pollution

    Directory of Open Access Journals (Sweden)

    Peter Rafaj

    2014-01-01

    Full Text Available This paper presents the methodology and results of impact assessment of renewable energy policies on atmospheric emissions of mercury in Europe. The modeling exercise described here involves an interaction of several models. First, a set of energy scenarios has been developed with the REMix (Renewable Energy Mix model that simulates different levels of penetration of renewable energies in the European power sector. The energy scenarios were input to the GAINS (Greenhouse Gas and Air Pollution Interactions and Synergies model, which prepared projections of mercury releases to the atmosphere through 2050, based on the current air pollution control policies in each country. Data on mercury emissions from individual sectors were subsequently disaggregated to a fine spatial resolution using various proxy parameters. Finally, the dispersion of mercury in the atmosphere was computed by the chemistry transport model, implemented to the air quality system, Polyphemus. The simulations provided information on changes in concentrations and depositions of various forms of mercury over Europe. Scenarios that simulate a substantial expansion of renewable energies within the power sector indicate extensive co-benefits for mercury abatement, due to the restructuring of the energy system and changes in the fuel mix. The potential for mercury reductions in Europe depends on the rate of fuel switches and renewable technology deployment, but is also influenced by the stringency and timing of the air quality measures. The overall scope for co-benefits is therefore higher in regions relying on coal combustion as a major energy source.

However, moxibustion in outpatient departments (OPDs of traditional Chinese medicine (TCM may be a source of indoor air pollution in hospitals. Some studies have investigated indoor air pollution during moxibustion in Chinese medicine clinics (CMCs and moxibustion rooms, demonstrating elevated air pollutants that pose a threat to the health of medical staff and patients. Our study investigated the indoor air pollutants of indoor carbon dioxide (CO2, carbon monoxide (CO, formaldehyde (HCHO, total volatile organic compounds (TVOCs, airborne particulate matter with a diameter of ≤10 µm (PM10 and ≤2.5 µm (PM2.5 during moxibustion in an acupuncture and moxibustion room of the OPD in a hospital in Taipei. To evaluate the different control strategies for indoor air pollution from moxibution, a comparison of air pollutants during moxibution among the methods of using alternative old moxa wools, local exhaust ventilation and an air cleaner was conducted. In this study, burning alternative old moxa wools for moxibustion obviously reduced all gaseous pollutants except for aerosols comparing burning fresh moxa wools. Using local exhaust ventilation reduced most of the aerosols after burning moxa. We also found that using an air cleaner was inefficient for controlling indoor air pollutants, particularly gaseous pollutants. Therefore, combining replacing alternative old moxa wools and local exhaust ventilation could be a suitable design for controlling indoor air pollution during moxibustion therapy.

  4. Effects and control of long-range transboundary air pollution. Report prepared within the framework of the Convention on Long-range Transboundary Air Pollution

    International Nuclear Information System (INIS)

    This tenth volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains the documents reviewed and approved for publication at the eleventh session of the Executive Body held at Geneva from 1 to 3 December 1993. Part One is the Annual Review of Strategies and Policies for Air Pollution Abatement. National emission data and forecasts for sulphur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ammonia (NH3) and carbon dioxide (CO2) from 1980 to 2005 are presented. Conclusions are drawn concerning the status of implementation of the sulphur and nitrogen oxides protocols on the basis of these data. Part Two is an executive summary of the 1992 Report on the Forest Condition in Europe. The main objective of this report is to give a condensed description of the condition of forests in Europe, as it has been assessed by the transnational and national annual surveys, carried out jointly by the ECE under the Convention on Long-range Transboundary Air Pollution and by the European Community (EC). Part Three is a summary report that focuses on the reduction of air pollution from heat and electric energy production. It is based on discussion papers submitted to the fifth ECE Seminar on Emission Control Technology for Stationary Sources, held in Nuremberg (Germany) from 10 to 14 June 1991. This chapter presents the main control techniques to reduce emissions from fuel combustion, which is a major contribution in most ECE countries to air pollution by sulphur and nitrogen compounds, carbon oxides, organic compounds, as well as heavy metals. Three principal abatement options are reviewed: fuel cleaning and fuel conversion, low-emission combustion processes, and flue gas cleaning processes. Both technical and economic aspects of the different measures are discussed

    Human impact on nature is increasing - not only in magnitude, but also in geographical scale. It has been known for centuries, that vegetation does not thrive near air pollution sources, but it was not before after the Second World War that the importance of long range transport of pollutants was realized - first for sulphur and nitrogen compounds, later for photochemical oxidants. The results have been acidification of rivers and lakes, forest dieback and eutrophication of inner waters. In recent decades the attention has been focused on global effects: Ozone depletion and increased greenhouse effect. Here air pollution threatens to alter the conditions of life on the entire Earth. In the political and public debate - and sometimes in science as well - the problems are treated separately. Since however, the basic phenomena all take place in the same atmosphere, they are more or less interrelated. Also the environmental effects must be considered a result of a complex impact. This complexity should be taken into account in the planning of an effective abatement strategy. (au) 11 refs.

    The production of phytotoxic air pollutants by cultures of Chlorella vulgaris and Euglena gracilis is considered. Algal and plant culture systems, a fumigation system, and ethylene, ethane, cyanide, and nitrogen oxides assays are discussed. Bean, tobacco, mustard green, cantaloupe and wheat plants all showed injury when fumigated with algal gases for 4 hours. Only coleus plants showed any resistance to the gases. It is found that a closed or recycled air effluent system does not produce plant injury from algal air pollutants.

    The quantifiable economic benefits of green roofs must be demonstrated if they are to succeed in North America. This paper presented the results of a study examining potential nitrogen oxide (NO{sub x}) uptake of green roofs in the metropolitan areas of Detroit, and Chicago with both traditional sedums and Nicotiana tabacum. The aim of the study was to present green roofs as a pollution abatement technology to aid in closing the cost gap that currently hinders market penetration of green roofs. Values from experiments exploring the uptake potential of 217 plant taxa were used to determine uptake capacities at an urban scale. Roof area estimates were then used to determine potential uptake capacity by covering various percentages of the area with vegetated roofs. Values were compared with annual emissions of both metropolitan areas. Results showed that greening 10 per cent of the roof areas aided in the uptake of NO{sub x} ranges between 0.25 and nearly 16 per cent. If green roofs are considered an abatement technology, a combination of cap-and-trade could allow the tonnes taken up by a green roof to be traded on the open market. While a green roof ignoring the benefit of air pollution uptake would generally break even between 39 and 40 years based upon investment of energy savings, the incorporation of air credits into the system reduced the time for return on investment to 36 years with sedum planted on the roof. If a plant with a higher uptake such as tobacco were placed on the roof, the break-even point was only 15 years. It was concluded that by expanding the number of contaminants with established emission markets, and expanding the variety of plants on green roofs, the economic benefits of green roofs could increase dramatically. 12 refs., 5 tabs., 6 figs.

    Over the past 250 years-since the Industrial Revolution accelerated the process of pollutant emission, which, until then, had been limited to the domestic use of fuels (mineral and vegetal) and intermittent volcanic emissions-air pollution has been present in various scenarios. Today, approximately 50% of the people in the world live in cities and urban areas and are exposed to progressively higher levels of air pollutants. This is a non-systematic review on the different types and sources of air pollutants, as well as on the respiratory effects attributed to exposure to such contaminants. Aggravation of the symptoms of disease, together with increases in the demand for emergency treatment, the number of hospitalizations, and the number of deaths, can be attributed to particulate and gaseous pollutants, emitted by various sources. Chronic exposure to air pollutants not only causes decompensation of pre-existing diseases but also increases the number of new cases of asthma, COPD, and lung cancer, even in rural areas. Air pollutants now rival tobacco smoke as the leading risk factor for these diseases. We hope that we can impress upon pulmonologists and clinicians the relevance of investigating exposure to air pollutants and of recognizing this as a risk factor that should be taken into account in the adoption of best practices for the control of the acute decompensation of respiratory diseases and for maintenance treatment between exacerbations.

It is necessary to perform an investigation for providing abatement and control of air pollution, in time of planning and manufacturing of control instruments. The manufacturing company has determined air pollution reduction instruments in this site, according to the emission suspended particulate and its climatic conditions. The air pollution reducer's instruments were used back-fither. But, this offer was not agreed by the Department of the Environment of Iran. Perhaps, this disagreement was announced just for another original problem, which was the site selection of plants. This research was on the filtration which has been offered by the manufacturing company, if this selection can improve the future regional air pollution. These figures, of course, were obtained from the present data and plume rise particulate, considering Gausian distribution mode for all the rural population and rivers rounding to the site, up to 5 km. The results showed that the produced particulates were less than permissible limit and the proposed methods will improve the complex air pollution difficulties So, the proposed methods were provided for increasing the control and operating the system for conducting of cyclone before input of particulate to the back-filter.

  15. Can air pollutant controls change global warming?

    International Nuclear Information System (INIS)

    Highlights: • Air pollution policies do not affect long-term climate targets. • Reduction of aerosols counteracts a fraction of the reduction of Kyoto forcing. • Air pollution policies may affect the rate of climate change in the short term. • There is no tradeoff between clean air and climate policies. - Abstract: In this paper we analyze the interaction between climate and air pollution policies using the integrated assessment model REMIND coupled to the reduced-form climate model MAGICC. Since overall, aerosols tend to cool the atmosphere, there is a concern that a reduction of pollutant emissions could accelerate global warming and offset the climate benefits of carbon dioxide emission reductions. We investigate scenarios which independently reduce emissions from either large-scale sources, such as power plants, or small-scale sources, such as cooking and heating stoves. Large-scale sources are likely to be easier to control, but their aerosol emissions are characterized by a relatively high sulfur content, which tends to result in atmospheric cooling. Pollution from small-scale sources, by contrast, is characterized by a high share of carbonaceous aerosol, which is an important contributor to global warming. We find that air pollution policies can significantly reduce aerosol emissions when no climate policies are in place. Stringent climate policies lead to a large reduction of fossil fuel use, and therefore result in a concurrent reduction of air pollutant emissions. These reductions partly reduce aerosol masking, thus initially counteracting the reduction of greenhouse gas forcing, however not overcompensating it. If climate policies are in place, air pollution policies have almost no impacts on medium- and long-term radiative forcing. Therefore there is no conflict of objectives between clean air and limiting global warming. We find that the stringency of air pollution policies may influence the rate of global temperature change in the first decade

  16. BLUME - the Berlin air pollution monitoring network

    International Nuclear Information System (INIS)

    This report compiles the BLUME air pollution chracteristics obtained in winter 1987/88. Figures and tables summarize and compare the measuring results obtained for sulfur dioxide, airborne particles, carbon monoxide, nitrogen oxides and ozone. Air pollution in winter 1987/88 was not as critical as in the previous years. The 1987/88 mean sulfur dioxide concentrations were found to be the lowest values determined since BLUME measurements started in 1975, and the mean values obtained for airborne particles and for most of the remaining pollutants were lower than in the previous year. The causes of these relatively low pollutant concentrations are discussed. (orig./BBR)

    International Nuclear Information System (INIS)

    Mercury pollution in the industrial environment of Chile was studied using hair as monitor. Data from samples representing people living in non-polluted and also from polluted areas show that hair is an effective and convenient indicator of environmental mercury pollution. A major source of mercury pollution and its transport is contaminated water. The method discussed is an inexpensive and convenient alternative to conventional ion-exchange processes which are generally very expensive, particulary for developing countries. (author)

  19. Epiphytic lichens and air pollution

    Energy Technology Data Exchange (ETDEWEB)

    De Wit, T.

    1978-01-01

    The WHEN workgroup has made an inventory of the epiphytic lichens on freestanding trees in The Netherlands, using a 5 km square-grid as a basis. On the basis of the number of lichen species per tree species per square, the squares were divided into six classes of epiphyte richness. The data for the west of the country were analyzed in more detail, resulting in a zone map. It appeared possible to construct a descriptive model of the correlation between SO/sub 2/ concentrations and epiphyte richness. At median winter SO/sub 2/ concentrations higher than 100..mu..g/m/sup 3/ only a few insensitive species occur. At lower concentrations winter peak values (98 percentile) are more important than median ones. The extent to which a species is restricted to epiphyte-rich squares is used as a measure for ranking the species according to sensitivity. The more sensitive species have disappeared from large areas of The Netherlands. Comparison of the present situation with data from around 1950 reveals a decline almost everywhere in the country. The southern and western parts of the country are impoverished, the area between Rotterdam and Den Haag and the area between Arnhem and Nijmegen in particular have become very poor. A further decline of the epiphytic lichen vegetation, in particular of the relatively rich areas, is expected. In fumigation experiments, using HF, SO/sub 2/, C/sub 2/H/sub 4/, O/sub 3/ and O/sub 3/ combined with SO/sub 2/ at realistic concentrations and prolonged exposition it was found that these air pollutants cause (under glasshouse conditions) significant morphological damage to all or some of the tested lichen species.

  20. Air pollution dispersion within urban street canyons

    Science.gov (United States)

    Taseiko, Olga V.; Mikhailuta, Sergey V.; Pitt, Anne; Lezhenin, Anatoly A.; Zakharov, Yuri V.

    A semi-empirical mathematical model, Urban Street Model (USM), is proposed to efficiently estimate the dispersion of vehicular air pollution in cities. This model describes urban building arrangements by combining building density, building heights and the permeability of building arrangements relative to wind flow. To estimate the level of air pollution in the city of Krasnoyarsk (in Eastern Siberia), the spatial distribution of pollutant concentrations off roadways is calculated using Markov's processes in USM. The USM-predicted numerical results were compared with field measurements and with results obtained from other frequently used models, CALINE-4 and OSPM. USM consistently yielded the best results. OSPM usually overestimated pollutant concentration values. CALINE-4 consistently underestimated these values. For OSPM, the maximum differences were 160% and for CALINE-4 about 400%. Permeability and building density are necessary parameters for accurately modeling urban air pollution and influencing regulatory requirements for building planning.

  1. Mapping real-time air pollution health risk for environmental management: Combining mobile and stationary air pollution monitoring with neural network models.

    Air pollution poses health concerns at the global scale. The challenge of managing air pollution is significant because of the many air pollutants, insufficient funds for monitoring and abatement programs, and political and social challenges in defining policy to limit emissions. Some governments provide citizens with air pollution health risk information to allow them to limit their exposure. However, many regions still have insufficient air pollution monitoring networks to provide real-time mapping. Where available, these risk mapping systems either provide absolute concentration data or the concentrations are used to derive an Air Quality Index, which provides the air pollution risk for a mix of air pollutants with a single value. When risk information is presented as a single value for an entire region it does not inform on the spatial variation within the region. Without an understanding of the local variation residents can only make a partially informed decision when choosing daily activities. The single value is typically provided because of a limited number of active monitoring units in the area. In our work, we overcome this issue by leveraging mobile air pollution monitoring techniques, meteorological information and land use information to map real-time air pollution health risks. We propose an approach that can provide improved health risk information to the public by applying neural network models within a framework that is inspired by land use regression. Mobile air pollution monitoring campaigns were conducted across Hamilton from 2005 to 2013. These mobile air pollution data were modelled with a number of predictor variables that included information on the surrounding land use characteristics, the meteorological conditions, air pollution concentrations from fixed location monitors, and traffic information during the time of collection. Fine particulate matter and nitrogen dioxide were both modelled. During the model fitting process we reserved

Pollution, the parts of contamination, can be either outside substances/ energies or normally happening contaminants. Contamination is regularly classed as point source or nonpoint source contamination.

  3. Air pollution in Karachi: a study

    International Nuclear Information System (INIS)

    Air population is a necessary adjunct to the advancement of civilisation. It was an offshoot or rapid industrialisation of Europe during the late nineteenth and early twentieth century when most of the industrial plants coming up in the big industrial cities were based on the use of coal as a source of energy. This caused an enormous amount of air pollution. Air pollution therefore is a man made phenomenon which creates environmental degradation and it generally builds up over a period of time. Pollution of Karachi which was less than half a million at the time of partition of India has crossed ten million mark during the last decade. This rapid and more or less unplanned expansion of population of this teeming metropolis has entailed environmental degradation of Karachi. As this matter needs detailed and in depth monitoring we have limited our scope to the study of its effect on air pollution alone. (A.B.)

  4. Indoor air pollution: a public health perspective

    International Nuclear Information System (INIS)

    Although official efforts to control air pollution have traditionally focused on outdoor air, it is now apparent that elevated contaminant concentrations are common inside some private and public buildings. Concerns about potential public health problems due to indoor air pollution are based on evidence that urban residents typically spend more than 90 percent of their time indoors, concentrations of some contaminants are higher indoors than outdoors, and for some pollutants personal exposures are not characterized adequately by outdoor measurements. Among the more important indoor contaminants associated with health or irritation effects are passive tobacco smoke, radon decay products, carbon monoxide, nitrogen dioxide, formaldehyde, asbestos fibers, microorganisms, and aeroallergens. Efforts to assess health risks associated with indoor air pollution are limited by insufficient information about the number of people exposed, the pattern and severity of exposures, and the health consequences of exposures. An overall strategy should be developed to investigate indoor exposures, health effects, control options, and public policy alternatives

    Kruzyzanowski, M. [WHO European Centre for Environment and Health, Bilthoven (Netherlands)

    1995-12-31

    Assessment of health risks due to air pollution should be an important indicator for setting the priorities for the environmental policies and for the abatement of the pollution. The scale of such assessment depends on the level, and scope, of the policy decisions relying on the evaluation. The analysis may range from an estimate of the health impact of a single pollution source, through the risk assessment in a community or a region of a country, to an international, or pan-continental approach. Such assessment, addressing population of all Europe, was one of the aims of the project `Concern for Europe`s Tomorrow` (CET). The WHO European Centre for Environment and Health completed this project, and the corresponding report, as a contribution to the Second European Conference on Environment and Health which gathered ministries of health and of environment from all European countries in Helsinki in June 1994. Using the report as the background information, the ministries have endorsed the `Environmental Health Action Plan for Europe`, the document formulating common environmental health policy of the Region. In this article, the summary of the evaluation will be presented and the main constraints of the pan-European approach will be addressed. (author)

  8. Public Communication on Urban Air Pollution

    International Nuclear Information System (INIS)

    The aim of this study was to analyze the state of public information in the field of air pollution in Spain. We conducted semi-structured interviews with members of public agencies, technical experts, scientists, and members of non governmental associations together with a documentary analysis of air pollution documents (plans, reports, etc.). We tried to characterize the information actions on air quality carried out in Spanish cities during the last years. In the results section we first analyze the ideas, concerns and considerations that underlie the actions of public information on air pollution, as well as the main challenges of public communication on this subject, according to the documents and the different experts consulted. We analyze the various contents of information transmitted nowadays (on levels of pollution, health impacts and mitigation or protection actions), as well as the mechanisms by which it is communicated, both continuously and in the case of threshold overcoming episodes. We also review the different media used to communicate air pollution information (Internet, mobile applications and other forms) and other issues such as information audiences, or the perceived impacts of information provided. Finally, the implications for more diverse and effective public involvement strategies in air pollution are discussed. (Author)

    Full Text Available There is a growing evidence on the hazards of ambient air pollution on fetal development. Several review articles have been published on the adverse fetal outcomes including low birth weight, preterm birth, small-for-gestational age, and congenital anomalies. Recent studies have linked ambient air pollution to gestational hypertension, and preeclampsia which may be related to the detrimental effect of ambient air pollution on placental growth and function. Short-term and long-term exposure to particulate air pollution may cause systemic inflammatory response which may trigger preterm delivery in pregnant women. Environmental toxic chemicals that alter intrauterine environment disregulates fetal epigenome causing epigenetic-mediated changes in gene expression that may be linked to later childhood and adulthood diseases. Exposure to ambient air pollution during the whole pregnancy especially in third-trimester may cause intrauterine vitamin D deficiency which is critical for the normal development of the lung, and immune system in fetus. However, more research is needed to understand the cause and effect interaction between air pollution and fetal development. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Full Text Available In this study, adsorption-oriented processes for pollutant removal from metal polycontaminated surface-finishing discharge water were applied individually as well as in combination with ion-exchange treatment to remove the remaining metal ions and organic load. Several materials were compared using batch experiments, namely an activated carbon, three ion-exchange resins (IRA 402Cl, IR 120H and TP 207, and two non-conventional cross-linked polysaccharide-based biosorbents (starch and cyclodextrin. This article presents the abatements obtained in chemical pollution as monitored by complete chemical analysis. For the same experimental conditions (similar discharge water, pollutant concentrations, stirring rate, contact time, and initial pH, the highest levels of pollutant removal were attained with the combined use of two materials, an activated carbon and a mixture of two ion-exchange resins. This physicochemical treatment effectively lowered the main pollutants present in the discharge water such as Cu, Ni and COD, by more than 96%, 79% and 74% respectively (average values for three samples, while the treatment with carbon alone lowered them by 58%, 9% and 70%, and resins alone by 85%, 61% and 16%. Similar interesting results were obtained with the cyclodextrin-based adsorbent and its use alone was sufficient to obtain decreases in Cu, Ni and COD of more than 94%, 77% and 67% respectively. The adsorption-oriented process using cyclodextrin polymer could be an advantageous approach for removing organic and metallic pollutants from metal surface-finishing discharge water due to the non-toxic character of CD to humans and the environment.

    Although biofilm-based biotechnologies exhibit a large potential as solutions for off-gas treatment, the high water content of biofilms often causes pollutant mass transfer limitations, which ultimately limit their widespread application. The present study reports on the proof of concept of the applicability of bioactive latex coatings for air pollution control. Toluene vapors served as a model volatile organic compound (VOC). The results showed that Pseudomonas putida F1 cells could be successfully entrapped in nanoporous latex coatings while preserving their toluene degradation activity. Bioactive latex coatings exhibited toluene specific biodegradation rates 10 times higher than agarose-based biofilms, because the thin coatings were less subject to diffusional mass transfer limitations. Drying and pollutant starvation were identified as key factors inducing a gradual deterioration of the biodegradation capacity in these innovative coatings. This study constitutes the first application of bioactive latex coatings for VOC abatement. These coatings could become promising means for air pollution control. PMID:25115963

    Foliar damage to trees by air pollution in Central and Eastern Europe has been a major scientific and political issue. Emissions of toxic gases such as sulfur dioxide and nitrogen oxides can have wide-ranging effects on local and regional vegetation that can be compounded by other environmental stresses to plant growth. Since uptake and physiological effects of these gases on tree leaves we largely, mediated by stomata, surrogate methods for estimating pollutant conductances into leaves and forest canopies may lead to risk assessments for major vegetation types that can then be used in regional planning. Management options to ameliorate or mitigate air pollutant damage to forests and losses in productivity are likely to be more difficult to widely implement than on-the-stack emissions abatement. Informed management and policy decisions regarding Central and Eastern European forests are dependent on the development of quantitative tools and models for risk assessment of the effects of atmospheric pollutants on ecosystem health and productivity.

    Full Text Available Air pollution has significant influence on the concentration of constituents in the atmosphere leading to effects like global warming and acid rains. To avoid such adverse imbalances in the nature, an air pollution monitoring system is utmost important. This paper attempts to develop an effective solution for pollution monitoring using wireless sensor networks (WSN on a real time basis namely real time wireless air pollution monitoring system. Commercially available discrete gas sensors for sensing concentration of gases like CO2, NO2, CO and O2 are calibrated using appropriate calibration technologies. These pre-calibrated gas sensors are then integrated with the wireless sensor motes for field deployment at the campus and the Hyderabad city using multi hop data aggregation algorithm. A light weight middleware and a web interface to view the live pollution data in the form of numbers and charts from the test beds was developed and made available from anywhere on the internet. Other parameters like temperature and humidity were also sensed along with gas concentrations to enable data analysis through data fusion techniques. Experimentation carried out using the developed wireless air pollution monitoring system under different physical conditions show that the system collects reliable source of real time fine-grain pollution data.

    Growing scientific evidence has shown that because people generally spend the majority of their time indoors, indoor pollution plays a significant role in affecting health and is thus an important health issue. Common indoor pollutants are environmental tobacco smoke, particulate matter, nitrogen dioxide, carbon monoxide, volatile organic compounds and biological allergens. In developing countries, relevant sources of indoor pollution include biomass and coal burning for cooking and heating. Concentrations of these pollutants can be many times higher indoors than outdoors. Indoor air pollution may increase the risk of irritation phenomena, allergic sensitisation, acute and chronic respiratory disorders and lung function impairment. Recent conservative estimates have shown that 1.5-2 million deaths per year worldwide could be attributed to indoor air pollution. Approximately 1 million of these deaths occur in children aged under 5 years due to acute respiratory infections and significant proportions of deaths occur due to chronic obstructive pulmonary disease and lung cancer in women. Today, indoor air pollution ranks tenth among preventable risk factors contributing to the global burden of disease. Further research is necessary to better evaluate the respiratory health effects of indoor pollution and to implement protective programmes for public health.

    Aunan, K.

    1995-10-01

    The objective of this report is to provide exposure-response functions for health effects and air pollution, which can be used in cost-effectiveness analyses of abatement measures. When cost-effective abatement strategies for air pollution are analyzed, and when air quality standards are set, it is important to have quantitative knowledge about health damage. In spite of their shortcomings, epidemiological studies provide a sound basis for exposure-response functions because they involve a random cross section of the population. In this report the exposure-response functions apply to the relation between air pollutant concentrations and relative effect frequencies, and involve the following health effect end-points: acute and chronic respiratory symptoms in children and adults, asthma episodes in children and adults, eye irritations, headache, lung damage in children, excess mortality, lung cancer incidence. The effects are attributed to one indicator component, which in many cases is particles, but for some effects NO{sub 2}, SO{sub 2}, O{sub 3}, or CO. A calculation procedure is suggested which makes it possible to estimate excess annual symptom-days for short-term effects using the annual average concentration. 103 refs., 1 table

    Full Text Available Once considered a taboo topic or stigma, cancer is the number one public health enemy in the world. Once a product of an almost untouchable industry, tobacco is indisputably recognized as a major cause of cancer and a target for anticancer efforts. With the emergence of new economic powers in the world, especially in highly populated countries such as China, air pollution has rapidly emerged as a smoking gun for cancer and has become a hot topic for public health debate because of the complex political, economic, scientific, and technologic issues surrounding the air pollution problem. This editorial and the referred articles published in this special issue of the Chinese Journal of Cancer discuss these fundamental questions. Does air pollution cause a wide spectrum of cancers? Should air pollution be considered a necessary evil accompanying economic transformation in developing countries? Is an explosion of cancer incidence coming to China and how soon will it arrive? What must be done to prevent this possible human catastrophe? Finally, the approaches for air pollution control are also discussed

  4. Climatological variability in regional air pollution

    International Nuclear Information System (INIS)

    Although some air pollution modeling studies examine events that have already occurred (e.g., the Chernobyl plume) with relevant meteorological conditions largely known, most pollution modeling studies address expected or potential scenarios for the future. Future meteorological conditions, the major pollutant forcing function other than emissions, are inherently uncertain although much relevant information is contained in past observational data. For convenience in our discussions of regional pollutant variability unrelated to emission changes, we define meteorological variability as short-term (within-season) pollutant variability and climatological variability as year-to-year changes in seasonal averages and accumulations of pollutant variables. In observations and in some of our simulations the effects are confounded because for seasons of two different years both the mean and the within-season character of a pollutant variable may change. Effects of climatological and meteorological variability on means and distributions of air pollution parameters, particularly those related to regional visibility, are illustrated. Over periods of up to a decade climatological variability may mask or overstate improvements resulting from emission controls. The importance of including climatological uncertainties in assessing potential policies, particularly when based partly on calculated source-receptor relationships, is highlighted

    1995-12-31

    The legal basis of the Swiss air pollution control policy is set by the Federal Law on the Protection of the Environment, which came into force in 1985. It aims to protect human beings, animals and plants, their biological communities and habitats against harmful effects or nuisances and to maintain the fertility of the soil. The law is source-oriented (by emission standards) as well as effect-oriented (by ambient air quality standards). To link both elements a two-stage approach is applied. In the first stage preventive measures are taken at the emitting sources, irrespective of existing air pollution levels. Emissions have to be limited by early preventive measures as much as technical and operational conditions allow and as far as economically acceptable (prevention principle). By this, air pollution shall be kept as low as possible as a matter of principle, without the environment having to be in danger first. In a second stage the measures are strengthened or backed up by additional measures if ambient air quality standards laid down in the Ordinance on Air Pollution Control are exceeded. At this second stage, protection of man and his environment has priority over economic considerations. (author)

It is therefore specific in the exposure variable. Air pollution health effects became evident during high air pollution episodes which occurred in the first decades of our century. Since then, legal and other control measures have led to lower air pollution levels. However, recent results from several studies indicate that lower levels of air pollution than the previously considered safe have serious adverse health effects. Although, there is increasingly agreement that air pollution, at levels measured today, affects health, there is still a lot to be understood concerning specific causal pollutants, biologic mechanisms involved and sensitive groups of individuals. The extent of potential confounding, time-considerations in air pollution effects, individual variation in air pollution exposure and exposure misclassification are some factors which complicate the study of these issues.

  8. The economics of particulate pollution abatement technologies for wood-waste-fired combustors

    International Nuclear Information System (INIS)

    A study was conducted to quantify the impact of new and improved particulate abatement equipment (PAE) on the economics of new and existing wood waste combustion systems. The operating characteristics of current PAE technology are summarized and the basis for cost estimates is established. The technologies include multicyclone collectors, wet scrubbers, fabric filter baghouses, electrostatic precipitators, and new versus retrofit installations. Capital costs were determined for 4 generic types of PAE and 4 cases for each PAE type according to GJ/h in steam enthalpy. Cost information was developed for wood waste energy systems with and without PAE. In the cost analysis, a hypothetical steam selling price is determined which will give a 25% return on pretax cash flow over a 20-year period. Additional costs of the PAE are applied to the energy system cash flows and the impact on average annual return is calculated. Results indicate reductions in internal rate of return of 3-6% for most PAE systems. 54 refs., 2 figs., 12 tabs

  9. the role of industry in air pollution

    International Nuclear Information System (INIS)

    Industry is among the main sources of air pollution in Lebanon. Industrial plants emits dangerous effluents affecting on human health and on population living in industrial zones. Personnel within industries ignore the dangerous effect of substances they use in their work and the toxic effect of gaseous, liquid and solid wastes produced and their impact on health and on environment. A major attention should be paid by Lebanese government to avoid the increasing of atmospheric pollution and must encourage the monitoring of air pollution and its effect on human target organs in the influenced zones. Within industries air is contaminated by gases, vapor, dusts in high rates. Attention has to be focused to the diseases due to breathing diseases, Asbestos, arterial high blood pressure, stress, digestive diseases and other

    Ruiz-Suarez, L. G.

    2007-05-01

    Mexico City is a megacity whose metropolitan area includes the country federal district, 18 municipalities of the State of Mexico. In year 1992, only 16 municipalities of the State of Mexico were part of MCMA. In year 1940 the Mexico City population was 1.78 millions in an area of 118 km2, in year 2000 the population was 17.9 millions in an area of 1,500 km2. Population has grown a ten fold whereas population density has dropped 20%. Total number of private cars has grown from 2,341,731 in year 1998 to 2,967,893 in year 2004. Nowadays, people and goods travel longer at lower speed to reach school, work and selling points. In addition highly efficient public transport lost a significant share of transport demand from 19.1 in 1986 to 14.3 in 1998. Air pollution is a public concern since early eighties last century; systematic public efforts have been carried out since late eighties. Energy consumption has steadily increased in the MCMA whereas emissions have also decreased. From year 2000 to 2004, the private cars fleet increased 17% whereas CO, NOx and COV emissions decreased between 20-30%. Average concentrations of criteria pollutants have decreased The number of days that the one-hour national standard for bad air quality was exceeded in year 1990 was 160. In year 2005 was 70. Research efforts and public policies on air pollution have been focused on public health. We are now better able to estimate the cost in human lives due to air pollution, or the cost in labor lost due to illness. Little if none at all work has been carried out to look at the effect of air pollution on private and public property or onto the cultural heritage. Few reports have can be found on the impact of air pollution in rural areas, including forest and crops, around the mega city. Mexico City is in the south end of a Valley with mountain ranges higher than 1000 m above the average city altitude. In spite the heavy loss of forested areas to the city, the mountains still retain large

  17. Pollution prevention at ports: clearing the air

    International Nuclear Information System (INIS)

    Seaports are major hubs of economic activity and of environmental pollution in coastal urban areas. Due to increasing global trade, transport of goods through ports has been steadily increasing and will likely continue to increase in the future. Evaluating air pollution impacts of ports requires consideration of numerous sources, including marine vessels, trucks, locomotives, and off-road equipment used for moving cargo. The air quality impacts of ports are significant, with particularly large emissions of diesel exhaust, particulate matter, and nitrogen oxides. The health effects of these air pollutants to residents of local communities include asthma, other respiratory diseases, cardiovascular disease, lung cancer, and premature mortality. In children, there are links with asthma, bronchitis, missed school days, and emergency room visits. The significance of these environmental health impacts requires aggressive efforts to mitigate the problem. Approaches to mitigation encompass a range of possibilities from currently available, low-cost approaches, to more significant investments for cleaner air. Examples of the former include restrictions on truck idling and the use of low-sulfur diesel fuel; the latter includes shore-side power for docked ships, and alternative fuels. A precautionary approach to port-related air pollution would encourage local production of goods in order to reduce marine traffic, greener design for new terminals, and state-of-the art approaches to emissions-control that have been successfully demonstrated at ports throughout the world

    The addition of graphene nanoplatelets (GNP) to TiO2 nanoparticles (NPs) has been recently considered as a method to improve the photocatalytic efficiency of TiO2 by favoring charge carrier separation. Here, we show that it is possible to improve the efficiency of GNP-TiO2 composites by controlling the shape, stability, and facets of TiO2 NPs grown on GNP functionalized with either COOH or NH2 groups, while adding ethylendiamine (EDA) and oleic acid (OA) during a hydrothermal synthesis. We studied the photocatalytic activity of all synthesized materials under UV-A light using phenol as a target molecule. GNP-TiO2 composites synthesized on COOH-functionalized GNP, exposing {101} facets, were more efficient at abating phenol than those synthesized on NH2-functionalized GNP, exposing {101} and {100} facets. However, neither of these composites was stable under irradiation. The addition of both OA and EDA stabilized the materials under irradiation; however, only the composite prepared on COOH-functionalized GNP in the presence of EDA showed a significant increase in phenol degradation rate, leading to results that were better than those obtained with TiO2 alone. This result can be attributed to Ti-OH complexation by EDA, which protects GNP from oxidation. The orientation of the most reducing {101} facets toward GNP and the most oxidizing {100} facets toward the solution induces faster phenol degradation owing to a better separation of the charge carriers.The addition of graphene nanoplatelets (GNP) to TiO2 nanoparticles (NPs) has been recently considered as a method to improve the photocatalytic efficiency of TiO2 by favoring charge carrier separation.

  19. Air pollution monitoring in downtown Rome, Italy

    International Nuclear Information System (INIS)

    This paper tables air pollution data indicating concentrations of sulfur dioxide, nitrous oxides, carbon monoxide, ozone, non-methane hydrocarbons (NMTHC) and particulate matter measured in downtown Rome during the period, April 1990 - March 1991. These data are analyzed according to National Air Quality Standards. Correlations are developed for nitrous oxide, NMTHC and ozone concentration trends as a function of solar radiation intensity. Analysis of the data reveals that the concentrations of the primary pollutants, carbon monoxide and nitrogen oxide, were very high in the winter months when building heating systems were operating under stable weather conditions. In many cases, the concentrations of carbon monoxide exceeded ambient air quality standards. The paper also discusses the need for the development of limits for NMTHC concentrations and including these limits in the Air Quality Standards

  2. Regulations Concerning Agriculture and Air Pollution

    Directory of Open Access Journals (Sweden)

    Chiara Bertora

    2010-03-01

    Full Text Available The main issues related to the atmospheric pollution are the stratospheric ozone depletion, the transboundary air pollution, the troposphere air quality and the climate change. The three last decades have seen the birth of several measures for the atmosphere safeguard. Agricultural activities play a key role in determining, preventing and mitigating atmospheric pollution. The emission to atmosphere of different ozone-depleting substances is regulated by the Montreal Protocol. The role of agriculture activity in ozone depletion is linked to the utilization of methyl bromide as soil sterilant and to the emission of nitrogen oxides and nitrous oxide, from agricultural soils. The Convention on long-range transboundary air pollution regulates the emission of several pollutants, i.e. sulphur dioxide, nitrogen oxides, ammonia, non methane volatile organic compounds, carbon monoxide, heavy metals, persistent organic pollutants, and tropospheric ozone. The agriculture sector is responsible for a large part of the emissions of ammonia and nitrogen oxides, mainly through manure management and nitrogen fertilization, and of most persistent organic pollutants, largely used in the past as insecticides and fungicides. The increase of the greenhouse gases (GHGs concentration in the atmosphere is under the control of the Kyoto Protocol. Agriculture accounts for 59-63% of global non-CO2 GHGs emissions but at the same time it contributes to the atmospheric CO2 concentration stabilisation through the substitution of fossil fuels by biofuels and the sequestration of C in soil and vegetal biomass. In this paper we provide an outline of the numerous scientific and legislative initiatives aimed at protecting the atmosphere, and we analyse in detail the agriculture sector in order to highlight both its contribution to atmospheric pollution and the actions aimed at preventing and mitigating it.

  3. Air pollution forecast in cities by an air pollution index highly correlated with meteorological variables

    International Nuclear Information System (INIS)

    There are many different air pollution indexes which represent the global urban air pollution situation. The daily index studied here is also highly correlated with meteorological variables and this index is capable of identifying those variables that significantly affect the air pollution. The index is connected with attention levels of NO2, CO and O3 concentrations. The attention levels are fixed by a law proposed by the Italian Ministries of Health and Environment. The relation of that index with some meteorological variables is analysed by the linear multiple partial correlation statistical method. Florence, Milan and Vicence were selected to show the correlation among the air pollution index and the daily thermic excursion, the previous day's air pollution index and the wind speed. During the January-March period the correlation coefficient reaches 0.85 at Milan. The deterministic methods of forecasting air pollution concentrations show very high evaluation errors and are applied on limited areas around the observation stations, as opposed to the whole urban areas. The global air pollution, instead of the concentrations at specific observation stations, allows the evaluation of the level of the sanitary risk regarding the whole urban population. (Author)

  6. Long-Term Benthic Macroinvertebrate Community Monitoring to Assess Pollution Abatement Effectiveness

    Energy Technology Data Exchange (ETDEWEB)

    Smith, John G [ORNL; Brandt, Craig C [ORNL; Christensen, Sigurd W [ORNL

    2011-01-01

    The benthic macroinvertebrate community of East Fork Poplar Creek (EFPC) in East Tennessee was monitored for 18 years to evaluate the effectiveness of a water pollution control program implemented at a major United States (U.S.) Department of Energy facility. Several actions were implemented to reduce and control releases of pollutants into the headwaters of the stream. Four of the most significant actions were implemented during different time periods, which allowed assessment of each action. Macroinvertebrate samples were collected annually in April from three locations in EFPC (EFK24, EFK23, and EFK14) and two nearby reference streams from 1986 through 2003. Significant improvements occurred in the macroinvertebrate community at the headwater sites (EFK24 and EFK23) after implementation of each action, while changes detected 9 km further downstream (EFK14) could not be clearly attributed to any of the actions. Because the stream was impacted at its origin, invertebrate recolonization was primarily limited to aerial immigration, thus, recovery has been slow. As recovery progressed, abundances of small pollution-tolerant taxa (e.g., Orthocladiinae chironomids) decreased and longer lived taxa colonized (e.g., hydropsychid caddisflies, riffle beetles, Baetis). While assessments lasting three to four years may be long enough to detect a response to new pollution controls at highly impacted locations, more time may be needed to understand the full effects. Studies on the effectiveness of pollution controls can be improved if impacted and reference sites are selected to maximize spatial and temporal trending, and if a multidisciplinary approach is used to broadly assess environmental responses (e.g., water quality trends, invertebrate and fish community assessments, toxicity testing, etc.).

  7. Experience with urban air pollution in Paterson, New Jersey and implications for air pollution communication.

    2012-01-01

    Communication about air pollution can help reduce health risks, but a scattered, largely qualitative literature on air pollution beliefs, attitudes, and behaviors raises questions about its effectiveness. A telephone survey of Paterson, New Jersey (USA) residents tested four hypotheses aimed toward integrating these findings. Self-reported sheltering indoors during high pollution, the recommended strategy, was predicted by perceived air quality and self-reported "sensitivity" to air pollution. Nearly a quarter of the sample reported mandatory outdoor activity (e.g., work) that might increase their exposures, but this factor did not significantly affect self-reported sheltering. Perceptions of air quality did not correlate strongly with official monitoring data (U.S. Air Quality Index (AQI)); even people who regularly sought AQI data relied upon sensory cues to high pollution, and secondarily upon health cues. Use of sensory and health cues, definitions of what makes someone sensitive to air pollution, and (less strongly) definitions of vulnerability to air pollution varied widely. The minority aware of the AQI were more likely to seek it if they had illnesses or saw themselves in the targeted AQI audience, yet less likely if they believed themselves sensitive to pollution. However, their sense of the AQI's match to their own experience was driven by whether they used sensory (yes) or health (no) cues, not by illness status. Some urban residents might not have access to AQI data, but this barrier seems outweighed by need to bridge interpretive gaps over definitions of air pollution, sensory perception, vulnerability, and health consequences.

    2009-07-01

    The need for mutual recognition of accurate measurement results made by competent laboratories has been very widely accepted at the international level e.g., at the World Trade Organization. A partial solution to the problem was made by the International Committee for Weights and Measures (CIPM) in setting up the Mutual Recognition Arrangement (CIPM MRA), which was signed by National Metrology Institutes (NMI) around the world. The core idea of the CIPM MRA is to have global arrangements for the mutual acceptance of the calibration certificates of National Metrology Institutes. The CIPM MRA covers all the fields of science and technology for which NMIs have their national standards. The infrastructure for the metrology of the gaseous compounds carbon monoxide (CO), nitrogen monoxide (Norway), nitrogen dioxide (NO{sub 2}), sulphur dioxide (SO2) and ozone (O{sub 3}) has been constructed at the national level at the Finnish Meteorological Institute (FMI). The calibration laboratory at the FMI was constructed for providing calibration services for air quality measurements and to fulfil the requirements of a metrology laboratory. The laboratory successfully participated, with good results, in the first comparison project, which was aimed at defining the state of the art in the preparation and analysis of the gas standards used by European metrology institutes and calibration laboratories in the field of air quality. To confirm the competence of the laboratory, the international external surveillance study was conducted at the laboratory. Based on the evidence, the Centre for Metrology and Accreditation (MIKES) designated the calibration laboratory at the Finnish Meteorological Institute (FMI) as a National Standard Laboratory in the field of air quality. With this designation, the MIKES-FMI Standards Laboratory became a member of CIPM MRA, and Finland was brought into the internationally-accepted forum in the field of gas metrology.

    Health impact of air pollution to children was studied over the last twenty years in heavily polluted parts of the Czech Republic during. The research program (Teplice Program) analyzed these effects in the polluted district Teplice (North Bohemia) and control district Prachatice (Southern Bohemia). Study of pregnancy outcomes for newborns delivered between 1994 and 1998 demonstrated that increase in intrauterine growth retardation (IUGR) was associated with PM10 and c-PAHs exposure (carcinogenic polycyclic aromatic hydrocarbons) in the first month of gestation. Morbidity was followed in the cohort of newborns (N=1492) up to the age of 10years. Coal combustion in homes was associated with increased incidence of lower respiratory track illness and impaired early childhood skeletal growth up to the age of 3years. In preschool children, we observed the effect of increased concentrations of PM2.5 and PAHs on development of bronchitis. The Northern Moravia Region (Silesia) is characterized by high concentrations of c-PAHs due to industrial air pollution. Exposure to B[a]P (benzo[a]pyrene) in Ostrava-Radvanice is the highest in the EU. Children from this part of the city of Ostrava suffered higher incidence of acute respiratory diseases in the first year of life. Gene expression profiles in leukocytes of asthmatic children compared to children without asthma were evaluated in groups from Ostrava-Radvanice and Prachatice. The results suggest the distinct molecular phenotype of asthma bronchiale in children living in polluted Ostrava region compared to children living in Prachatice. The effect of exposure to air pollution to biomarkers in newborns was analyzed in Prague vs. Ceske Budejovice, two locations with different levels of pollution in winter season. B[a]P concentrations were higher in Ceske Budejovice. DNA adducts and micronuclei were also elevated in cord blood in Ceske Budejovice in comparison to Prague.

  13. Air pollution control at a DOE facility

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) plutonium production program Produced some of the greatest scientific and engineering accomplishments of all time. It is remarkable to consider the accomplishments of the Manhattan Project. The Reactor on the Hanford Site, the first production reactor in the world, began operation only 13 months after the start of construction. The DOE nuclear production program was also instrumental in pioneering other fields such as health physics an radiation monitoring. The safety record of these installations is remarkable considering that virtually every significant accomplishment was on the technological threshold of the time. One other area that the DOE Facilities pioneered was the control of radioactive particles and gases emitted to the atmosphere. The high efficiency particulate air filter (HEPA) was a development that provided high collection efficiencies of particulates to protect workers and the public. The halogen and noble gases also were of particular concern. Radioactive iodine is captured by adsorption on activated carbon or synthetic zeolites. Besides controlling radioncuclide air pollution, DOE facilities are concerned with other criteria pollutants and hazardous air pollutant emissions. The Hanford Site encompasses all those air pollution challenges

    Hazardous chemicals escape to the environment by a number of natural and/or anthropogenic activities and may cause adverse effects on human health and the environment. Increased combustion of fossil fuels in the last century is responsible for the progressive change in the atmospheric composition. Air pollutants, such as carbon monoxide (CO), sulfur dioxide (SO{sub 2}), nitrogen oxides (NOx), volatile organic compounds (VOCs), ozone (O{sub 3}), heavy metals, and respirable particulate matter (PM2.5 and PM10), differ in their chemical composition, reaction properties, emission, time of disintegration and ability to diffuse in long or short distances. Air pollution has both acute and chronic effects on human health, affecting a number of different systems and organs. It ranges from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults, aggravating pre-existing heart and lung disease, or asthmatic attacks. In addition, short- and long-term exposures have also been linked with premature mortality and reduced life expectancy. These effects of air pollutants on human health and their mechanism of action are briefly discussed. - The effect of air pollutants on human health and underlying mechanisms of cellular action are discussed.

    2011-06-01

    A globalizing world increases immigration between nations, raising the question of how acculturation (or its lack) of immigrants and their descendants to host societies affects risk perceptions. A survey of Paterson, New Jersey, residents tested acculturation's associations with attitudes to air pollution and its management, and knowledge of and self-reported behaviors concerning air pollution. Linguistic and temporal proxy measures for acculturation were independent variables along with ethnicity, plus controls for gender, age, education, and income in multivariate analyses. About one-fifth of contrasts between non-Hispanic whites, non-Hispanic blacks, English-interviewed Hispanics, and Spanish-interviewed Hispanics were statistically significant (Bonferroni-corrected) and of medium or higher affect size, with most featuring the Spanish-interviewed Hispanics. Knowledge variables featured the most significant differences. Specifically, Spanish-interviewed Hispanics reported less concern, familiarity with pollution, recognition of high pollution, and vigorous outdoor activity, and greater belief that government overregulates pollution than English-interviewed Hispanics (and than the other two groups on most of these variables too). English-interviewed Hispanics did not differ from non-Hispanic whites, but did on several variables from non-Hispanic blacks. Temporal proxies of acculturation among the foreign-born were far less significant, but concern and familiarity with air pollution increased with time spent in the United States, while belief in overregulation and a positive trend in New Jersey pollution increased with time in the nation of origin. Implications of these acculturation and ethnicity findings for risk perception/communication research and practice are discussed. PMID:21231941

  1. Efficient air pollution regulation of coal-fired power in China

    Science.gov (United States)

    Feng, Therese

    This dissertation evaluates monetary external costs of electricity generation in the People's Republic of China and implications for efficient pollution control policy. It presents an integrated assessment of environmental damages of air emissions of a representative new coal-fired plant in urban areas of north and south China. The simulation evaluates the nature and magnitude of damages in China, transboundary effects in Japan and Korea, and global greenhouse gas warming impacts. The valuation is used to identify efficient abatement policy for Chinese plants over time; evaluate benefits of differentiated policies; and consider the importance of dynamic policy. Potential annual damages of operating a 600-MW power plant without controls in China today would be 43-45 million (U.S. 1995). Annual local damages of 37-40 million far exceed transboundary or greenhouse gas damages (1.4 million and $4.6 million respectively). The largest component of damages is the risk of human mortality and chronic morbidity from long-term exposure to fine particles. Efficient pollution control minimizes the sum of abatement costs and residual unabated damages. Because monetary damages reflect sufferers' willingness to pay to avoid environmental risks, the choice of efficient controls is fundamentally tied to societal values and preferences. The optimal path for Chinese abatement moves from modest dispersion measures at present to combined dispersion and emission controls approaching those of current-day United States, by 2050. The inclusion of transboundary and greenhouse damages does not substantively alter local policies. Welfare benefits are gained by differentiating abatement policy by pollutant, meteorological parameters, and by population density. An analysis of optimal one-time investment in abatement for a plant in a growing economy suggests that some investment is optimal at all incomes but no single level of abatement is suitable for all economies.

  2. Land survey map of air pollutants

    International Nuclear Information System (INIS)

    The first step toward finding a solution to the problems with air pollution is the realization of a land survey map of polluters and a constant acquisition of data from periodical controls of emission of harmful materials, which will be carried out with a determined dynamic. Such a land survey map is not a project which should be finished within a strict time limit, but is intended to create all conditions for a periodical monitoring of emission of harmful materials from registered polluters in order to make a periodical, exact picture of the quantity of harmful materials, which are conveyed by polluters in certain city, a part of the state or the whole country.

    Traditional physicochemical and biological techniques, as well as advanced oxidation processes (AOPs), are often inadequate, ineffective, or expensive for industrial water reclamation. Within this context, the electrochemical technologies have found a niche where they can become dominant in the near future, especially for the abatement of biorefractory substances. In this critical review, some of the most promising electrochemical tools for the treatment of wastewater contaminated by organic pollutants are discussed in detail with the following goals: (1) to present the fundamental aspects of the selected processes; (2) to discuss the effect of both the main operating parameters and the reactor design on their performance; (3) to critically evaluate their advantages and disadvantages; and (4) to forecast the prospect of their utilization on an applicable scale by identifying the key points to be further investigated. The review is focused on the direct electrochemical oxidation, the indirect electrochemical oxidation mediated by electrogenerated active chlorine, and the coupling between anodic and cathodic processes. The last part of the review is devoted to the critical assessment of the reactors that can be used to put these technologies into practice. PMID:26654466

  4. Long-memory property in air pollutant concentrations

    Science.gov (United States)

    Chelani, Asha

    2016-05-01

    In the present paper, long-memory in air pollutant concentrations is reviewed and outcome of the past studies is analyzed to provide the possible mechanism behind temporal evolution of air pollutant concentrations. It is observed that almost all the studies show air pollutant concentrations over time possess persistence up to a certain limit. Self-organized criticality of air pollution, multiplicative process of pollutant concentrations, and uniformity in emission sources leading to self-organized criticality are few of the phenomena behind the persistent property of air pollutant concentrations. The self-organized criticality of air pollution is linked to atmosphere's self-cleansing mechanism. This demonstrates that inspite of increasing anthropogenic emissions, self-organized criticality of air pollution is sustained and has low influence of human interventions. In the future, this property may, however, be perturbed due to continuous air pollution emissions, which may influence the accuracy in predictions.

  5. Endothelial damage due to air pollution

    2010-05-01

    Full Text Available The first human deaths due to air pollution were recorded in the mid-20th century. There were 6,000 cases of illness recorded in Donora, Pennsylvania, in 1948 and 20,000 in London in 1952; 15 and 4,000 cases of death, respectively, were allegedly ascribed to air pollution. Since then, many countries have adopted standards of air quality in order to protect environmental and human health, although the quality of the air in some industrialized countries remains worrying. Emerging countries in the Far East and South America are also cause for concern because of the growth in the population, industrialization and transport. The WHO World Health Report 2002 estimated that air pollutants, particularly PM10, are associated with a mortality rate of 5% for cancer of the respiratory system, 2% for cardiovascular diseases and about 1% for respiratory tract infections. These estimates consider the mortality but not the morbidity rate, which would increase proportionally the number of cases of these pathologies, despite the difficulty in evaluation.

  6. Assessment of Air Pollution and GHG Mitigation Strategies in Malaysia using the GAINS Model

    International Nuclear Information System (INIS)

    Planning for future energy development, taking into account the national obligations to mitigate climate change and air quality pressures is a major challenge faced by Malaysia. This research facilitates the impact assessment of simultaneous control of air pollution and GHG abatement through a set of emission scenarios while considering current and future Malaysian policies. The IIASAs GAINS (Greenhouse Gas-Air Pollution Interactions and Synergies) model is used for the estimation of emissions and costs, and the outputs of the MESSAGE and MAED energy models provide the underlying energy projections by 2050. Results show that current air-quality policies are efficient in keeping emissions growth at moderate rate, however, significant reduction potential exists if best available control technologies are introduced. Malaysian climate policies - modeled here for power sector - aiming at the -40 % decrease in carbon-intensity, result in important reductions of air pollutants, while the overall co-benefits can be substantial if other sectors are tackled by climate strategies. Initial results indicate the reduction of air pollutant control cost due to climate measures is comparable to the invoked cost-increase in power sector by 2030. Thereby, these co-benefits help to moderate total expenditures for meeting national climate policy targets. (author)

  8. Coupling Noble Metals and Carbon Supports in the Development of Combustion Catalysts for the Abatement of BTX Compounds in Air Streams

    Directory of Open Access Journals (Sweden)

    Sergio Morales-Torres

    2015-04-01

    Full Text Available The catalytic combustion of volatile organic compounds (VOCs is one of the most important techniques to remove these pollutants from the air stream, but it should be carried out at the lowest possible temperature, saving energy and avoiding the simultaneous formation of nitrogen oxides (NOx. Under these experimental conditions, the chemisorption of water generated from VOCs combustion may inhibit hydrophilic catalysts. Nowadays, a wide variety of carbon materials is available to be used in catalysis. The behavior of these hydrophobic materials in the development of highly active and selective combustion catalysts is analyzed in this manuscript. The support characteristics (porosity, hydrophobicity, structure, surface chemistry, etc. and the active phase nature (noble metals: Pt, Pd and dispersion were analyzed by several techniques and the results correlated with the dual adsorptive and/or catalytic performance of the corresponding catalysts. The coupling of highly active phases and carbon materials (activated carbons, honeycomb coated monoliths, carbon aerogels, etc. with tuneable physicochemical properties leads to the complete abatement of benzene, toluene and xylenes (BTX from dilute air streams, being selectively oxidized to CO2 at low temperatures.

  9. Effect of substrate depth and rain-event history on the pollutant abatement of green roofs

    International Nuclear Information System (INIS)

    This study compares the effectiveness of two different thickness of green roof substrate with respect to nutrient and heavy metal retention and release. To understand and evaluate the long term behaviour of green roofs, substrate columns with the same structure and composition as the green roofs, were exposed in laboratory to artificial rain. The roofs act as a sink for C, N, P, zinc and copper for small rain events if the previous period was principally dry. Otherwise the roofs may behave as a source of pollutants, principally for carbon and phosphorus. Both field and column studies showed an important retention for Zn and Cu. The column showed, however, lower SS, DOC and metal concentrations in the percolate than could be observed in the field even if corrected for run-off. This is most probably due to the difference in exposition history and weathering processes. Highlights: • Extensive roof greening can lead to increased DOC and nutrients runoff. • Studied green roofs retained over 80% of atmospheric heavy metal loads (Zn, Cu, Pb). • Substrate layer thickness had no significant impact on metal retention. • Column experiments showed no decrease in the long term heavy metal retention. -- The green roofs tested, showed variable retention capacity for the common pollutants, but were especially efficient in heavy metals retention, which long-term evolution was evaluated in simultaneous column experiments

    Environmental factors such as ambient air pollution have been associated with congenital heart defects. The aim of this study was to investigate the association between gestational exposure to air pollution and the risk of congenital heart defects. We conducted a registry-based cohort study with a total of 135,527 live- and still-births in the Tel-Aviv region during 2000-2006. We used a Geographic Information System-based spatiotemporal approach with weekly inverse distance weighting modeling to evaluate associations between gestational exposure to ambient air pollution during weeks 3-8 of pregnancy and the risk for congenital heart defects. The following pollutants were studied: carbon monoxide, nitrogen-dioxide, ozone, sulfur-dioxide and particulate matter with aerodynamic diameter smaller than 10 μm and 2.5 μm (PM10, PM2.5 respectively). Logistic models, adjusted for socio-demographic covariates were used to evaluate the associations. We found that maternal exposure to increased concentrations of PM10 was associated with multiple congenital heart defects (adjusted OR 1.05, 95% CI: 1.01 to 1.10 for 10 μg/m(3) increment). An inverse association was observed between concentrations of PM2.5 and isolated patent ductus arteriosus (adjusted OR 0.78, 95% CI: 0.68 to 0.91 for 5 µg/m(3) increment). Sensitivity analyses showed that results were consistent. Generally there were no evidence for an association between gaseous air pollutants and congenital heart defects.Our results for PM10 and congenital heart defects confirm results from previous studies. The results for PM2.5 need further investigations. PMID:23623715

    Beryllium-7 and sulphurhexaflourid has been used as tracers in measurements designed to enable an estimate of the ratio of the outdoor to indoor time-integrated concentration for aerosols and non-reactive gasses of outdoor origin with a special reference to the reduction in inhalation dose that can be achieved by staying indoors during a pollution episode, especially a reactor accident. The effect of operating a vacuum cleaner during the pollution episode and airing shortly after is also investigated. Earlier relevant literature is reviewed and shows goos agreement with the results in this study. Protection factor from 1-12 has been found. (author)

    Full Text Available Air pollution from cement factory is classified as one of the sources of air pollution. The control of the air pollution by addressing the wind field dynamics was the main objective of the paper. The dynamics of dispersion showed a three way flow which was calculated and explained accordingly. The 3D model showed good level of accuracy by determining field values of air deposited pollutants. Mean concentration of diffusing pollutants was shown to be directly proportional to the plume angular displacement. The 2D model explained the details of the wind field dynamics and proffers a solution which may be relevant in controlling air pollution from anthropogenic sources.

  16. Climate Change and Air Pollution: Exploring the Synergies and Potential for Mitigation in Industrializing Countries

    Directory of Open Access Journals (Sweden)

    Frances C. Moore

    2009-03-01

    Full Text Available Air pollutants such as tropospheric ozone and black carbon (soot also contribute to the greenhouse effect. Black carbon is thought to be the second or third most important anthropogenic contributor to global warming, while troposheric ozone is the fourth most important. Both are also major components of indoor and outdoor air pollution. This paper reviews the existing literature of the health, economic, and climatic impacts of tropospheric ozone and black carbon emissions, together with mitigation options. The local nature of many of the impacts, combined with their short atmospheric lifetime and the existence of cost-effective abatement technologies that are already widely deployed in developed countries means reducing these emissions provides a highly climatically-effective mitigation option that is also appropriate to the development strategy of industrializing countries.

    All WtE (waste-to-energy) plants, based on combustion or other thermal processes, need an efficient gas cleaning for compliance with legislative air emission standards. The development of gas cleaning technologies started along with environment protection regulations in the late 1960s. Modern APC (air pollution control) systems comprise multiple stages for the removal of fly ashes, inorganic and organic gases, heavy metals, and dioxins from the flue gas. The main technologies and devices used for abatement of the various pollutants are described and their basic principles, their peculiarities, and their application are discussed. Few systems for cleaning of synthesis gas from waste gasification plants are included. Examples of APC designs in full scale plants are shown and cautious prospects for the future development of APC systems are made. PMID:25022549

    The technology of heavy water production uses huge water volumes. After the recovery of H2S, the exhaustion water is treated by acidulation, stripping and alkalinization to neutralize the noxious effect of H2S. In the paper we demonstrate that by shutting down the power, even for a short period of time, do to the big water volume, the H2S from the acid water could be very dangerous. In order to avoid the accidental pollution with H2S when the power is shut down we proposed a gravitational device. (authors)

    Full Text Available Air quality monitoring in most developing countries is not routinely conducted, and in some urban areas such information does not even exist, though signs of deteriorating air quality and health problems related to air pollution are visible. By measuring air pollutants (i.e., Nitrogen Oxides, ozone, suspended particulates matter (PM10, and trace elements e.g. lead, this study investigated air quality in Nairobi, one of the largest cities in eastern Africa and the capital of Kenya. Sampling was done once a week from February to April 2003. Hourly average concentrations of NOx and O3 were measured using a technique that is based on "chemilumiscent" reaction at a site connecting two main highways in Nairobi (University and Uhuru from 9:00 a.m. to 5:00 p.m. PM10 was collected using “Gent” Stacked Filter Unit (SFU air sampler fitted with nucleopore filters (0.4 and 8.0 mm pore size for fine and coarse filters, respectively that were analyzed for trace elements by Energy Dispersive X-ray Fluorescent (EDXRF technique. An automatic vehicle counter was used for determining the vehicle density at the sampling site. Results show that most pollutants, for example, lead (0.05 1 to 1.106 µg/m3, bromine (LLD to 0.43 µg/m3, NO2 (0.011-0.976 ppm, NO (0.001-0.2628 ppm and O3 (LLD-0.1258 ppm are within the WHO guidelines. PM10 levels (66.66 - 444.45 µg/m3 were above the WHO guidelines for most of the days, with coarse particulate accounting for more than 70%. Strong correlation (r = 0.966 between fine (0.4 µm particulates, NOx, and motor vehicle density, indicate the importance of traffic as a common source for both fine particulates and NOx.

    The Metropolitan Area of Mexico City (MAMC) is an outstanding case of a fast urban development with lagging, and thus insufficient, massive transportation facilities. This has given rise to a distorted transportation system that accounts for most of the air pollution problem of the city and constitutes a drag on economic development. In this paper, we first describe the MAMC geographical conditions, its growth in physical and economic terms, its transportation system, the ensuring air pollution problems together with some of the mitigation actions undertaken. Afterwards the results of a survey of the displacements of individuals within the city and the time spent on these are presented, to then draw some considerations on the negative economic impact it represents.

  5. Personal exposure of children to air pollution

    Science.gov (United States)

    Ashmore, M. R.; Dimitroulopoulou, C.

    Changes over recent decades in outdoor concentrations of air pollutants are well documented. However, the impacts of air pollution on an individual's health actually relate not to these outdoor concentrations but to their personal exposure in the different locations in which they spend time. Assessing how personal exposures differ from outdoor concentrations, and how they have changed over recent decades, is challenging. This review focuses on the exposure of children, since they are a particularly sensitive group. Much of children's time is spent indoors, and childhood exposure is closely related to concentrations in the home, at school, and in transport. For this reason, children's personal exposures to air pollutants differ significantly from both those of adults and from outdoor concentrations. They depend on a range of factors, including urbanisation, energy use, building design, travel patterns, and activity profiles; analysis of these factors can identify a wider range of policy measures to reduce children's exposure than direct emission control. There is a very large variation in personal exposure between individual children, caused by differences in building design, indoor and outdoor sources, and activity patterns. Identifying groups of children with high personal exposure, and their underlying causes, is particularly important in regions of the world where emissions are increasing, but there are limited resources for environmental and health protection. Although the science of personal exposure assessment, with the associated measurement and modelling techniques, has developed to maturity in North America and western Europe over the last 50 years, there is an urgent need to apply this science in other parts of the world where the effects of air pollution are now much more serious.

    International Nuclear Information System (INIS)

    During fiscal year 1994, this author used the Bernard J. Steigerwald Opportunity for Independent Study, sponsored by US Environmental Protection Agency's Office of Air Quality Planning and Standards (Research Triangle Park, N.C.), to develop a group of quarterly indexes for adjusting or escalating air pollution control costs from one period to another. In all, nine indexes were developed, one equipment cost index (ECI) for each of nine control device categories. For convenience to the reader, additional indexes for two other equipment categories--available as part of the Producer Price Indexes compiled by the US Bureau of Labor Statistics--are also presented here. These 11 indexes--collectively known as the Vatavuk Air Pollution Control Cost Indexes (VAPCCI)--can be used to escalate costs from the initial (base) period (first quarter 1994) forward to any quarter in the future. To date, final indexes have been calculated (and are presented at the end of this article) for the second, third, and fourth quarters of 1994, and first quarter 1995; preliminary indexes are provided for second quarter 1995. Quarterly updates of these cost indexes will be computed as soon as the required input data become available. To date, no other set of cost indexes has been developed for such a wide array of pollution-control devices

  8. The state of transboundary air pollution 1992 update. Report prepared within the framework of the Convention on Long-range Transboundary Air Pollution

    International Nuclear Information System (INIS)

    This ninth volume of the series of Air Pollution Studies, published under the auspices of the Executive Body for the Convention on Long-range Transboundary Air Pollution, contains documents reviewed and approved for publication at the tenth session of the Executive Body held at Geneva from 17 to 19 November 1992. Part One is the Annual Review of Strategies and Policies for Air Pollution Abatement. It is compiled on the basis of national data and reports received up to 31 December 1992. National emission data and forecasts for sulphur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ammonia (NH3), and carbon dioxide (CO2) from 1980 to the year 2005 is presented. Part Two contains results of scenario analysis for sulphur abatement strategies. It is concluded, inter alia, that strategies can be found which, by differentiating emission reductions, provide greater environmental benefit than a uniform reduction at the same cost. It is also shown that a small number of high-emitting countries in Central Europe have significant impact on deposition of sulphur throughout Europe, and that emission reduction in these countries proves to be a cost-effective way of moving towards critical loads in Europe as a whole. Most of the scenarios analysed are based on reductions of current deposition in relation to critical loads, i.e., a decrease in the exceedances of critical loads. Part Three is an executive summary of the 1992 Report on Forest Condition in Europe, carried out under the International Cooperative Programme for Assessment and Monitoring of Air Pollution Effects on Forests. The full report has been jointly published by ECE and the Commission of the European Communities. It summarizes the results of surveys carried out in 1991 in 28 European countries and in several additional regions, conducted in accordance with common guidelines. Of 214 million hectares of forest in Europe (including major parts of the forests in the western part of the Russian

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

    The validity of using the Air Pollution Index (API) to assess health impacts of air pollution and potential modification by individual characteristics on air pollution effects remain uncertain. We applied distributed lag non-linear models (DLNMs) to assess associations of daily API, specific pollution indices for PM10, SO2, NO2 and the weighted combined API (APIw) with mortality during 2003-2011 in Guangzhou, China. An increase of 10 in API was associated with a 0.88% (95% confidence interval (CI): 0.50, 1.27%) increase of non-accidental mortality at lag 0-2 days. Harvesting effects appeared after 2 days' exposure. The effect estimate of API over lag 0-15 days was statistically significant and similar with those of pollutant-specific indices and APIw. Stronger associations between API and mortality were observed in the elderly, females and residents with low educational attainment. In conclusion, the API can be used to communicate health risks of air pollution. PMID:26057478

    Epidemiological studies have linked daily concentrations of urban air pollution to mortality, but few have investigated specific traffic sources that can inform abatement policies. We assembled a database of >100 daily, measured and modelled pollutant concentrations characterizing air pollution in London between 2011 and 2012. Based on the analyses of temporal patterns and correlations between the metrics, knowledge of local emission sources and reference to the existing literature, we selected, a priori, markers of traffic pollution: oxides of nitrogen (general traffic); elemental and black carbon (EC/BC) (diesel exhaust); carbon monoxide (petrol exhaust); copper (tyre), zinc (brake) and aluminium (mineral dust). Poisson regression accounting for seasonality and meteorology was used to estimate the percentage change in risk of death associated with an interquartile increment of each pollutant. Associations were generally small with confidence intervals that spanned 0% and tended to be negative for cardiovascular mortality and positive for respiratory mortality. The strongest positive associations were for EC and BC adjusted for particle mass and respiratory mortality, 2.66% (95% confidence interval: 0.11, 5.28) and 2.72% (0.09, 5.42) per 0.8 and 1.0 μg/m(3), respectively. These associations were robust to adjustment for other traffic metrics and regional pollutants, suggesting a degree of specificity with respiratory mortality and diesel exhaust containing EC/BC.

  12. Multivariate analysis between air pollutants and meteorological variables in Seoul

    International Nuclear Information System (INIS)

    Multivariate analysis was conducted to analyze the relationship between air pollutants and meteorological variables measured in Seoul from January 1 to December 31, 1999. The first principal component showed the contrast effect between O3 and the other pollutants. The second principal component showed the contrast effect between CO, SO2, NO2, and O3, PM10, TSP. Based on the cluster analysis, three clusters represented different air pollution levels, seasonal characteristics of air pollutants, and meteorological conditions. Discriminant analysis with air environment index (AEI) was carried out to develop an air pollution index function. (orig.)

  13. An integrated assessment of acidification, eutrophication and ozone formation using regional scale air pollution models

    International Nuclear Information System (INIS)

    In order to achieve a cost-effective reduction of acidification, eutrophication and ozone formation in Europe, possible abatement strategies are discussed and optimised with respect to cost effectiveness using the RAINS and EMEP models, with a spatial resolution of 150 km x 150 km. For a detailed evaluation of the impact of the proposed abatement strategies on a smaller region, in case the Flanders region, more detailed computations have been carried out, using regional scale air pollution models with spatial resolutions varying from 5 km to 60 km. The results were used for an integrated assessment of acidification, eutrophication and ozone formation in Flanders for the period 1999-2010. The assessment includes a comparison with intermediate and long-term policy goals, an evaluation of the effects. The results show an increase of the dominant role of ammonia with respect to acidification and eutrophication in 2010. The AOT60 reductions aimed at in the proposed EU abatement strategy could be confirmed, but results for the AOT40 were found to be much more uncertain. (Author)

  14. Public Perception of Urban Air Pollution: An Exploratory Study

    International Nuclear Information System (INIS)

    This report presents the results of a qualitative study using focus groups aimed at understanding the beliefs and attitudes of the population towards air pollution, its levels, causes, health impacts and possible mitigation and protection actions. The study sample consisted of members of the general population, between 18 and 65 years living in Barcelona. The analysis of the group discussion indicates that there is little awareness among participants about air pollution risks. The causes of air pollution are relatively known but there is little knowledge about pollution levels and types of pollutants. We found a low level of perceived personal risk associated to air pollution that coexists with a general awareness of the health impacts of air pollution, a low level of concern about the problem and a low level of personal involvement in mitigation and self protection measures. Participants reported no use of existing information services about air pollution. (Author)

  15. Synergies in the Asian energy system: Climate change, energy security, energy access and air pollution

    International Nuclear Information System (INIS)

    We use the MESSAGE model to examine multiple dimensions of sustainable development for three Asian regions in a set of scenarios developed for the Asian Modelling Exercise. Using climate change mitigation as a starting point for the analysis, we focus on the interaction of climate and energy with technology choice, energy security, energy access, and air pollution, which often have higher policy priority than climate change. Stringent climate policies drive the future energy supply in Asia from being dominated by coal and oil to a more diversified system based mostly on natural gas, coal with CCS, nuclear and renewable energy. The increase in diversity helps to improve the energy security of individual countries and regions. Combining air pollution control policies and universal energy access policies with climate policy can further help to reduce both outdoor and indoor air pollution related health impacts. Investments into the energy system must double by 2030 to achieve stringent climate goals, but are largely offset by lower costs for O and M and air pollution abatement. Strong focus on end-use efficiency also helps lowering overall total costs and allows for limiting or excluding supply side technologies from the mitigation portfolio. Costs of additional energy access policies and measures are a small fraction of total energy system costs. - Highlights: ► Half of added investments in energy offset by lower costs for O and M and air pollution. ► Costs for achieving universal energy access much smaller than energy system costs. ► Combined emissions and access policies further reduce air pollution impacts on health. ► Strong focus on end-use efficiency allows for more flexibility on energy sources. ► Stringent climate policy can improve energy security of Asian regions.

  16. Protection of plants against air pollutants: Role of chemical protectants

    International Nuclear Information System (INIS)

    The protection of plants against air pollution damage can best be achieved either by developing pollution-tolerant cultivars or by using chemical protectants. Use of chemical protectants such as pesticides, growth regulators, anti-oxidants, fertilizers, etc. is a short-term solution to reduce the risk of air pollution damage. In addition, these protectants help in understanding the mechanism of air pollution toxicity and provide a scientific basis for assessing crop losses in field conditions. 95 refs

    3-D Differential Absorption Scanning Lidar (DIASL) system has been designed with small size, light weight, and suitable for installation in various vehicles and places for monitoring of air pollutants and displays a detailed real-time temporal and spatial variability of trace gases via the Google Earth. The fast scanning techniques and visual information can rapidly identify the locations and sources of the polluted gases and assess the most affected areas. It is helpful for Environmental Protection Agency (EPA) to protect the people's health and abate the air pollution as quickly as possible. The distributions of the atmospheric pollutants and their relationship with local metrological parameters measured with ground based instruments will also be discussed. Details will be presented in the upcoming symposium.

  18. Air pollution monitoring in Amman, Jordan

    International Nuclear Information System (INIS)

    In 1985, a collaborative research program was established between the Royal Scientific Society of Jordan and Environment Canada, Pollution Measurement Division, Ottawa, Canada, with the objective of developing an air pollution monitoring network for Amman and preparing recommendations for national air quality standards and national emission standards for Jordan. Four monitoring sites were established in residential and commercial areas of Amman. Carbon monoxide, nitrogen dioxide, sulphur dioxide and total suspended particle matter (TSP) were measured at the Downtown station. At the other sites only TSP was measured. A short-term monitoring program carried out with a mobile monitoring unit showed relatively low levels of sulfur dioxide, carbon monoxide and nitrogen dioxide at the RSS, Naser and Marka sites as compared to the Downtown site. Continuous analyzers purchased from Environment SA, France, were used to measure sulfur dioxide, carbon monoxide and nitrogen dioxide; Sierra-Anderson high volume samplers equipped with glass fiber filters were used to collect total suspended particulates samples. Gaseous pollutants were continuously measured at the Downtown site and TSP samplers were operated on a three day schedule at all sites. Sampling began in July 1986 and continues to the present

    Most major cities around the world experience periods of elevated air pollution levels, which exceed international health-based air quality standards (Kumar et al., 2013). Although it is a global problem, some of the highest air pollution levels are found in rapidly expanding cities in India and China. The sources, emissions, transformations and broad effects of meteorology on air pollution are reasonably well accounted in air quality control strategies in many developed cities; however these key factors remain poorly constrained in the growing cities of countries with emerging economies. We focus here on Delhi, one of the largest global population centres, which faces particular air pollution challenges, now and in the future.

  20. Air pollution and sick-leaves. A case study using air pollution data from Oslo

    International Nuclear Information System (INIS)

    During the last decade an increasing amount of studies have investigated the relationship between air pollution and human health effects. In this study we investigate how these effects in turn induce reduced labour productivity in terms of sick-leaves, which is an important factor in assessment of air pollution costs in urban areas. For this purpose we employ a logit model along with data on sick-leaves from a large office in Oslo and different air pollutants. Our results indicate that sick-leaves are significantly associated with particulate matter (PM10), while the associations with SO2 and NO2 are more ambiguous. We also try to estimate the induced social costs in terms of lost labour productivity and increased governmental expenditures, although these estimates are more uncertain. 17 refs

  1. Heterogeneous Photocatalysis: Fundamentals and Application for Treatment of Polluted Air

    Directory of Open Access Journals (Sweden)

    Tomašić, V.

    2011-07-01

    Full Text Available The use of heterogeneous photocatalysts for the abatement of environmental problems has received increased attention during the last three decades. The photocatalyst used in most of these studies was titanium dioxide. This fact relates to the unique physical and chemical properties of titanium dioxide and similar semiconductor materials, such as ZnO, MgO,WO3, Fe2Oa, CdS, etc. that may be utilized for a wide range of potential applications. Specifically, upon ultraviolet irradiation these materials exhibit photocatalytic activity that enables the oxidative destruction of a wide range of organic compounds and biological species on their surface. In addition, these materials may also exhibit photocatalytically induced superhydrophilicity that converts the hydrophobic character of the surface to hydrophilic when exposed to UV light. This causes the formation of uniform water films on the surface of these materials, which prevents the adhesion of inorganic or organic components and thus retains a clean surface on the photocatalyst. Photocatalytic materials may be deployed on surfaces of various substrates, such as glass, ceramics or metals to provide layers that exhibit photocatalytic activity when they are exposed to light. Excitation of a photocatalyst leads to the creation of electrons and holes in the semiconductor material. Furthermore, these electrons and holes interact with molecules adsorbed on the semiconductor and can induce charge transfer process that results in the degradation of the adsorbate. The commercial potentials of heterogeneous photocatalysis are huge, including medical applications, application in the field of architecture (particularly for the cultural heritage purposes, facade paints, etc., automotive and food industries (cleaner technologies, non-fogging glass and mirrors, product safety, textile and glass industry, as well as in environmental protection (water and air purification and disinfection.

  2. Bangkok and its air pollution problem

    Energy Technology Data Exchange (ETDEWEB)

    Bangkok is the city on a former river delta and is a very flat area. The topography is unremarkable but being only a few kilometers (about 20) from the sea in the Gulf of Bangkok, the City experiences the sea breeze every afternoon and evening. The natural phenomenon is caused by the uplifting of hot air from the sun-baked ground and heat generation in the city, to be replaced by the cooler air from the sea, which is to the south. During the nighttime the sea breeze ceases to operate as the ground temperature cools down. The late night and early morning is characterized by the calm or no wind. With 2.1 million vehicles, the city has a serious problem of carbon monoxide from the gasoline vehicles stuck in the traffic on start and stop cycles, while particulate matter is the result of diesel vehicles. Hydrocarbons mainly result from two-stroke motorcycles and tuk-tuk (three-wheeled) taxis. Air pollution in Bangkok and major cities of Thailand is the result of emissions from gasoline, diesel, and LPG fueled vehicles, which contribute to the observed levels of carbon monoxide, lead, particulate matter, sulfur dioxide, nitrogen dioxide, ozone and hydrocarbons. The industrial activities contribute smaller share due to tall stacks and more efficient combusting processes and pollution control.

  4. Air pollution prevention at the Hanford Site: Status and recommendations

    International Nuclear Information System (INIS)

    With the introduction of the Clean Air Act Amendments of 1990 and other air and pollution prevention regulations, there has been increased focus on both pollution prevention and air emissions at US DOE sites. The Pollution Prevention (P2) Group of WHC reviewed the status of air pollution prevention with the goal of making recommendations on how to address air emissions at Hanford through pollution prevention. Using the air emissions inventory from Hanford's Title V permit, the P2 Group was able to identify major and significant air sources. By reviewing the literature and benchmarking two other DOE Sites, two major activities were recommended to reduce air pollution and reduce costs at the Hanford Site. First, a pollution prevention opportunity assessment (P2OA) should be conducted on the significant painting sources in the Maintenance group and credit should be taken for reducing the burning of tumbleweeds, another significant source of air pollution. Since they are significant sources, reducing these emissions will reduce air emission fees, as well as have the potential to reduce material and labor costs, and increase worker safety. Second, a P2OA should be conducted on alternatives to the three coal-fired powerhouses (steam plants) on-site, including a significant costs analysis of alternatives. This analysis could be of significant value to other DOE sites. Overall, these two activities would reduce pollution, ease regulatory requirements and fees, save money, and help Hanford take a leadership role in air pollution prevention

    In the urban environment atmospheric pollution by PM10 (particulate matter with a diameter less than 10 x 10-6 m) is a problem that can have adverse effects on human health, particularly increasing rates of respiratory disease. The main contributors to atmospheric PM10 in the urban environment are road traffic, industry and power production. The urban tree canopy is a receptor for removing PM10s from the atmosphere due to the large surface areas generated by leaves and air turbulence creat...

    Feddema, J. J.; Meierding, T. C.

    Maps of damage to marble tombstones in the urban region of Philadelphia demonstrate a close spatial correspondence with airborne pollutant concentrations. Mean recession rates on upper tombstone faces are an order of magnitude greater (3.5 mm (100a) -1) in the center of the city than they are 20 km away in the suburbs and countryside (cause sufficient gypsum accumulation within the stones to exfoliate the durable surface layer. Old photos of tombstones in central Philadelphia cemeteries show that exfoliation greatly accelerated between 1930 and 1960, concurrent with increases in SO 2 levels. Recent improvements in air quality are likely to have slowed stone deterioration.

  8. Mortality and air pollution: lessons from statistics

    International Nuclear Information System (INIS)

    Cross sectional studies which attempt to link persistent geographic differences in mortality rates with air pollution are reviewed. Some early studies are mentioned and detailed results are given for seven major contemporary studies, two of which are still in the publication process. Differences among the studies are discussed with regard to statistical techniques, trends in the results over time (1959 to 1974), and interpretation and use of the results. The analysis concludes that there are far too many problems with this technique to allow causality to be firmly established, and thus the results should not be used for cost benefit or policy analysis

  11. Integrating environmental taxes on local air pollutants with fiscal reform in Hungary: simulations with a computable general equilibrium model

    International Nuclear Information System (INIS)

    This paper describes the Fiscal Environmental Integration Model (FEIM) and its use to examine the merits of introducing a set of air pollutant emission taxes and stringent abatement requirements based on best commonly available control technology. These environmental protection strategies are examined both independently and in combination. In addition, Hungary has very high VAT, employment, and income tax rates and therefore might receive more than the usual advantage from using environmental tax revenues to reduce other taxes. We therefore also examine the economic and environmental implications of different uses of the revenues generated by the air pollutant emissions taxes. FEIM is a CGE model of the Hungarian economy that includes sectoral air pollution control costs functions and execution options that allow examination of the key policy choices involved. We developed and ran a baseline and seven scenarios with FEIM. The scenarios centered on introduction of environmental load fees (ELF) on emissions of SO2, NOx, and particulates and emission abatement requirements (EAR) for these pollutants. (Author)

  12. Air pollution and economics: Alternate use of fuels in small scale industries

    International Nuclear Information System (INIS)

    In developing countries the problem of air pollution was recognized earlier, however, it has acquired a greater dimension due to the conventional use of low grade fuels like coal, baggase, rice husk, etc. having high sulphur and ash content. The industrial sources contribute about 30--40% of the total emissions. In India, the small scale industries (low investment group) contribute about 60--80% of the total industrial emissions. These industries are characterized with various environmental pollution problems due to cluster of small scale industries located in sensitive area; use of low grade fuel, primitive processing techniques without emission abatement facilities etc., thus leading to enormous pollution in an confined region. Acute need was felt to reduce the pollution problem associated with small scale industries by use of cleaner fuel so as to reduce the localized problem. The paper presents the emissions associated with use of coal/coke, natural gas, LPG, and propane along with the fuel cost for small scale industrial sector of Agra, Firozabad and Mathura region. The studies carried out would find applicability to meet the air pollution standards based on shift in fuel and associated cost

  13. EPA issues offshore air pollution regulations

    International Nuclear Information System (INIS)

    This paper reports that the Environmental Protection Agency has issued regulations equalizing offshore air pollution rules with onshore standards except in the Gulf of Mexico. The rules hold platforms and drilling rigs within 25 miles of states' seaward boundaries to the same state, local, and federal requirements as if they were located in the corresponding onshore areas. If EPA finds state regulations are adequate, it will delegate to the coastal state the implementation and enforcement authority for the OCS rules. Air emissions sources more than 25 miles offshore will be subject only to federal requirements. EPA said within 2 years the rules will result in significant benefits to certain onshore areas currently violating smog standards

In this work it is studied a biological treatment (bio filtration) for air polluted by xylene and styrene where the microorganisms are adhered at synthetic fiber, these degrade to the organic compounds that across in gaseous state and they are mineralized toward CO2 and H2O. The characteristics of temperature, p H, concentration of organic compound and mineral parameters, as well as, the biomass quantity have been optimized for that bio filters efficiency were greater than those reported in other works.

  15. Elemental bioaccumulators in air pollution studies

    International Nuclear Information System (INIS)

    K0-Based instrumental neutron activation analysis (k0 INAA) was used to determine the concentrations of Cr, Fe, Co, Zn, Se, Sb and Hg in the vascular plants Cistus salvifolius and Inula viscosa and in the lichen Parmelia sulcata. The samples were collected in the neighbourhood of industrial complexes. The elemental accumulation in the vascular plants and the lichen are compared to optimize the choice of the bioaccumulator. It is concluded that P.sulcata seems to be the best accumulator of the three species for the element studied; Cistus salvifolius is sensitive to the contents of Zn, Fe, Cr and Sb in the air; Inula viscosa seems to accumulate Fe, Sb, Co, Cr and Zn. Nevertheless, it is concluded that lichen is a good air pollution indicator, while the vascular plants are not due to the large seasonal variations found in the elemental concentrations.

  16. Does urban vegetation mitigate air pollution in northern conditions?

    International Nuclear Information System (INIS)

    It is generally accepted that urban vegetation improves air quality and thereby enhances the well-being of citizens. However, empirical evidence on the potential of urban trees to mitigate air pollution is meager, particularly in northern climates with a short growing season. We studied the ability of urban park/forest vegetation to remove air pollutants (NO2, anthropogenic VOCs and particle deposition) using passive samplers in two Finnish cities. Concentrations of each pollutant in August (summer; leaf-period) and March (winter, leaf-free period) were slightly but often insignificantly lower under tree canopies than in adjacent open areas, suggesting that the role of foliage in removing air pollutants is insignificant. Furthermore, vegetation-related environmental variables (canopy closure, number and size of trees, density of understorey vegetation) did not explain the variation in pollution concentrations. Our results suggest that the ability of urban vegetation to remove air pollutants is minor in northern climates. -- Highlights: ► The ability of northern urban vegetation to remove air pollutants is minor. ► Vegetation-related environmental variables had no effect on air pollution levels. ► The ability of vegetation to clean air did not differ between summer and winter. ► Dry deposition passive samplers proved applicable in urban air pollution study. -- The ability of urban vegetation to remove air pollutants seems to be minor in northern climates

    During the last years, specific air quality problems have been detected in the urban area of Porto (Portugal). Both PM10 and NO2 limit values have been surpassed in several air quality monitoring stations and, following the European legislation requirements, Air Quality Plans were designed and implemented to reduce those levels. In this sense, measures to decrease PM10 and NO2 emissions have been selected, these mainly related to the traffic sector, but also regarding the industrial and residential combustion sectors. The main objective of this study is to investigate the efficiency of these reduction measures with regard to the improvement of PM10 and NO2 concentration levels over the Porto urban region using a numerical modelling tool - The Air Pollution Model (TAPM). TAPM was applied over the study region, for a simulation domain of 80 × 80 km2 with a spatial resolution of 1 × 1 km2. The entire year of 2012 was simulated and set as the base year for the analysis of the impacts of the selected measures. Taking into account the main activity sectors, four main scenarios have been defined and simulated, with focus on: (1) hybrid cars; (2) a Low Emission Zone (LEZ); (3) fireplaces and (4) industry. The modelling results indicate that measures to reduce PM10 should be focused on residential combustion (fireplaces) and industrial activity and for NO2 the strategy should be based on the traffic sector. The implementation of all the defined scenarios will allow a total maximum reduction of 4.5% on the levels of both pollutants.

  18. Review of air pollution and health impacts in Malaysia

    International Nuclear Information System (INIS)

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

  19. Air pollution - Trends in Austria 1980 - 2002

    International Nuclear Information System (INIS)

    The Austrian federal environmental office (Umweltbundesamt) carries out an annual inventory of the air pollution to fulfill obligatory duties derived from national and international agreements (UNFCCC; United Nations Framework Convention on Climate Change, Kyoto-protocol, EU monitoring mechanism (Decision 93/389/EWG). This inventory includes the anthropogenic emissions for the period 1980 - 2002 and the steps followed to reduce them. It is divided into 11 parts as follows: 1. summary, 2. inventory basis, 3. greenhouse gases (emissions trends 1990-2002, actual development 2001-2, carbon dioxide, methane, nitrogen dioxide, F- gases (SF6, partial fluorinated hydrocarbons, total fluorinated hydrocarbons), 4. ozone promoters (nitrogen oxides, hydrocarbons, carbon monoxide, methane), 5. acidification and eutrophication (sulfur dioxide, ammonia, nitrogen oxides), 6. dust, 7. heavy metals (cadmium, lead, mercury), 8. persistent organic pollutants (polycyclic aromatic hydrocarbons, dioxine, hexachlorobenzene), 9. pollution trends by sectors (power generation, traffic, industry, agriculture), 10. international comparison of Austrian emissions (greenhouse gases, sulphur dioxide, nitrogen oxides, hydrocarbons without methane, ammonia, carbon monoxide), 11. bibliography and an appendix. Data were collected following the guidelines by the International panel on climate exchange and the EMEP/CORINAIR emission inventory guidebook. Those chapters which are in the INIS subject scope were treated individually. 36 ref., 30 tabls., 74 figs. (nevyjel)

    An investigation repeated for the third time on susceptibility for SO/sub 2/ of 7 varieties of lettuce resulted in a reliable difference between the most and least susceptible variety; the others produced differences between individual plants within the varieties. Ethylene fumigations of tomato plants during five to six hours at concentrations of 0.5 to 3 ppm caused no visible reaction. A fumigation with 3 ppm for 23 hours resulted in a strong epinastic reaction at the base of the leaf petioles and curling of the young growing leaves. An apparatus was constructed to fumigate herbaceous plants, shrubs and trees in their natural environment and under normal climatic conditions. With this apparatus daffodil, tulip and Ixia were fumigated for 3 hours with HF in a concentration of 0.030 ppm. The most susceptible varieties showed leaf tip damage to an extent of 2 to 4 cm. Some time after an aluminium factory came into operation, injury to trees and shrubs occurred in the neighborhood; farm crops were not affected. For some factories the opportunity was given to carry out measurements on the amount of air pollution in the neighborhood of these factories before production starts, to estimate how much extra air pollution may be caused by the new factory.

  1. Study of urban air pollution in Thailand

    International Nuclear Information System (INIS)

    The Office of Atoms for Peace has conducted a monitoring study of urban air pollution in Thailand for years. The primary objective of the project was to support the use of nuclear-related techniques for research and monitoring studies on air pollution. The databases obtained have been analyzed and interpreted by statistical methods including source identification using receptor model. This paper reports the work of 2002 at a heavy traffic area in Bangkok. A Gent sampler was set at the curbside of a major road in Bangkok to collect fine and coarse particles routinely on a weekday for 24 hours, once a week. The filter samples were analyzed for elemental concentrations by use of instrumental neutron activation analysis. Black carbon was separately determined by means of the reflectance measurement of the filter sample. In the report, the methodologies and the results of analyses of fine and coarse particles on filters collected in 2002 are presented. The study of the applicability of certified reference material was done by analyses of two standard reference materials provided by JAERI, i.e., NIST 1632c and NIES No.8. The comparisons of the measured and certified values are also given in the paper. (author)

    Emission sources as well as wind speed and direction and MLH are important factors which influence high air pollutant concentrations. This is generally known (Schäfer et al., 2006) but the detailed understanding of processes directing certain air pollutant concentrations like HCHO is not complete. To study these processes a long-term campaign in Augsburg, Germany, was performed since March 2012. The concentrations of NO, NO2, O3 and HCHO, which were measured with a DOAS from OPSIS across a main traffic road and a nearby park area, are analysed. A ceilometer CL31 from Vaisala which is an eye-safe commercial mini-lidar system is applied to detect layering of the lower atmosphere continuously. Special software for this ceilometer with MATLAB provides routine retrievals of lower atmosphere layering from vertical profiles of laser backscatter data. Meteorological data were measured by a ground-based weather station at the measurement site as well as taken from monitoring data archives of the German National Meteorological Service (DWD), which are measured by radiosondes (Oberschleißheim). Correlation analyses are applied to show the coupling of temporal variations of NO, NO2, O3 and HCHO concentrations with temperature, mixing layer height and wind speed. HCHO which is emitted from both anthropogenic and biogenic sources is studied especially.

  3. Monitoring of pyrocatechol indoor air pollution

    Eškinja, I.; Grabarić, Z.; Grabarić, B. S.

    Spectrophotometric and electrochemical methods for monitoring of pyrocatechol (PC) indoor air pollution have been investigated. Spectrophotometric determination was performed using Fe(III) and iodine methods. The adherence to Beer's law was found in the concentration range between 0 and 12 μg ml - for iodine method at pH = 5.7 measuring absorbance at 725 nm, and in the range 0-30 μg ml - for Fe(III) method at pH = 9.5 measuring absorbance at 510 nm. The former method showed greater sensitivity than the latter one. Differential pulse voltammetry (DPV) and chronoamperometric (CA) detection in flow injection analysis (FIA) using carbon paste electrode in phosphate buffer solution of pH = 6.5 was also used for pyrocatechol determination. The electrochemical methods allowed pyrocatechol quantitation in submicromolar concentration level with an overall reproducibility of ± 1%. The efficiency of pyrocatechol sampling collection was investigated at two temperatures (27 and 40°C) in water, 0.1 M NaOH and 0.1 M HCl solutions. Solution of 0.1 M HCl gave the best collection efficiency (95.5-98.5%). A chamber testing simulating the indoor pollution has been performed. In order to check the reliability of the proposed methods for monitoring of the indoor pyrocatechol pollution, the air in working premises with pyrocatechol released from meteorological charts during mapping and paper drying was analyzed using proposed methods. The concentration of pyrocatechol in the air during mapping was found to be 1.8 mg m -3 which is below the hygienic standard of permissible exposure of 20 mg m -3 (≈ 5 ppm). The release of pyrocatechol from the paper impregnated with pyrocatechol standing at room temperature during one year was also measured. The proposed methods can be used for indoor pyrocatechol pollution monitoring in working premises of photographic, rubber, oil and dye industries, fur and furniture dyeing and cosmetic or pharmaceutical premises where pyrocatechol and related

  11. An integrated assessment of climate change, air pollution, and energy security policy

    International Nuclear Information System (INIS)

    This article presents an integrated assessment of climate change, air pollution, and energy security policy. Basis of our analysis is the MERGE model, designed to study the interaction between the global economy, energy use, and the impacts of climate change. For our purposes we expanded MERGE with expressions that quantify damages incurred to regional economies as a result of air pollution and lack of energy security. One of the main findings of our cost-benefit analysis is that energy security policy alone does not decrease the use of oil: global oil consumption is only delayed by several decades and oil reserves are still practically depleted before the end of the 21st century. If, on the other hand, energy security policy is integrated with optimal climate change and air pollution policy, the world's oil reserves will not be depleted, at least not before our modeling horizon well into the 22nd century: total cumulative demand for oil decreases by about 24%. More generally, we demonstrate that there are multiple other benefits of combining climate change, air pollution, and energy security policies and exploiting the possible synergies between them. These benefits can be large: for Europe the achievable CO2 emission abatement and oil consumption reduction levels are significantly deeper for integrated policy than when a strategy is adopted in which one of the three policies is omitted. Integrated optimal energy policy can reduce the number of premature deaths from air pollution by about 14,000 annually in Europe and over 3 million per year globally, by lowering the chronic exposure to ambient particulate matter. Only the optimal strategy combining the three types of energy policy can constrain the global average atmospheric temperature increase to a limit of 3 oC with respect to the pre-industrial level.

  13. Air pollution burden of illness from traffic in Toronto

    International Nuclear Information System (INIS)

    This paper examined the health impacts of air pollution from traffic in Toronto. The paper provided a review of scientific studies on the health effects of vehicle pollution as well as a quantitative assessment of the economic costs and the burden of illness attributed to traffic pollution in Toronto. The report also assessed air pollution and traffic trends in the city, and outlined initiatives being conducted to reduce vehicle-related pollution. The study used the new air quality benefits tool (AQBAT) which determines the burden of illness and the economic impacts of traffic-related air pollution. Air modelling specialists were consulted in order to determine the contribution of traffic-related pollutants to overall pollution levels using data on traffic counts and vehicle emissions factors. The air model also considered dispersion, transport and and the transformation of compounds emitted from vehicles. Results of the study showed that traffic pollution caused approximately 440 premature deaths and 1700 hospitalizations per year. Children in the city experienced more than 1200 acute bronchitis episodes per year as a result of air pollution from traffic. Mortality-related costs associated with traffic pollution in Toronto were estimated at $2.2 billion. It was concluded that the city must pursue the implementation of sustainable transportation policies and programs which foster and enable the expansion and use of public transport. 47 refs., 8 tabs., 9 figs

    International Nuclear Information System (INIS)

    With this project, a biomonitoring survey will be carried out with epiphytic lichens. The lichens Parmelia sulcata (or caperata) will be collected from olive trees about 1-2 m above the ground, using a 10x10 km grid or 50x50 km gird. In total, about 300 sampling sites will be set up. Within one sampling site, variations in elemental concentrations of lichen material taken from several trees of the same species will be analyzed to obtained the local variation for each element (made in 10% of the grid). In addition some typical soil samples will be collected so that the contribution of soil suspended in air particulate matter can be recognized. The samples will be analyzed for ∼50 elements by NAA and PIXE. The expected results will be integrated data sets, which will be used in the next step for application of a statistical procedure to identify particular pollution sources. The project also consists of exposure experiments with lichen transplant samples at several sampling sites, which are representative for the regions under study. In addition at each sampling site air particular matter and total deposition will be collected monthly, during 1 year. The aim is to establish a quantitative relationship between results obtained with the lichen transplant samples and with air particulate matter and total deposition.

    Most air pollution monitoring technologies accompany a time-consuming sample treatment and provide pollution information only for a local area. Thus, they have a critical restriction in monitoring time-dependent pollution variation effectively over the wide range of area both in height and in width. LIDAR(Light Detection And Ranging) is a new technology to overcome such drawbacks of the existing pollution monitoring technologies and has long been investigated in the advanced countries. The coal of this project is to develop the mobile air pollution monitoring system and to apply the system to the detection of various pollutants, such as ozone, nitrogen dioxide, sulfur dioxide and aerosols.

  19. Research into forest decline and air pollution in France: major findings and relevance for policy applications

    International Nuclear Information System (INIS)

    The DEFORPA Programme (Forest Decline and Air Pollution) (1984-1991) aimed at identifying the causes of decline in conifers in the French mountains. The yellowing Norway spruce (Picea abies K), which reveals a Mg deficiency, results primarily from the long-term acidification and cation depletion of originally poor soils under the influence of acid deposition and harvest. Other air pollution effects include stream acidification in the Vosges area and eutrophication of forest ground vegetation. Ozone effects remain uncertain. Climatic anomalies affecting vulnerable standards in relation with their history were found to be the main causes of silver fir (Abies alba Mill.) dieback. Despite these air pollution effects and visible damage, the productivity of the studied species has increased over the past century; the causes (climate change, increased N deposition and CO2 levels, silviculture) are not yet identified. Critical loads are thought to be a valuable tool for defining further emissions abatements to protect the sensitive parts of the forest ecosystem (flora, soils, surface waters). 45 refs., 1 fig., 3 tabs

    International Nuclear Information System (INIS)

    Bioindication using epiphytic lichens has developed rapidly in the last decades. Both mapping of lichen vegetation and multielement analysis of Hypogymnia physodes collected on a national scale were used. A simple method based on the assessment of the cover and frequency of crustose, foliose and fruticose lichens on different tree species was performed in 1991 and 1995 and the so-called Index of Atmospheric Purity (IAP) was calculated, providing a picture of the general air quality in the country. However, by analysis of lichen material using k0-instrumental neutron activation analysis detailed information about its composition and levels of pollutants was obtained. In the present work an attempt to combine the IAP results with the quantitative levels of certain trace elements together with available results for SO2 in the atmosphere using multivariate statistical methods is presented and discussed.

    The current objective of the project Analysis of Air Pollution and Greenhouse Gases'' is to develop a study of emissions and emission sources that could easily be linked to models of economic activity. Initial studies were conducted to evaluate data currently available linking activity rates and emissions estimates. The emissions inventory developed for the National Acid Precipitation Assessment Program (NAPAP) presents one of the most comprehensive data sets, and was chosen for our initial studies, which are described in this report. Over 99% of the SO{sub 2} emissions, 98% of the NO{sub x} emission and 57% of the VOC emissions from area sources are related to fuel combustion. The majority of emission from these sources are generated by the transportation sector. Activity rates for area sources are not archived with the NAPAP inventory; alternative derivations of these data will be part of the future activities of this project. The availability and completeness of the fuel heat content data in the NAPAP inventory were also studied. Approximately 10% of the SO{sub 2} emissions, 13% of the NO{sub x} emissions and 46% of the VOC emissions are generated by sources with unavailable data for fuel heat content. Initial estimates of pollutant emission rate per unit fuel heat content. Initial estimates of pollutant emission rate per unit fuel heat content were generated. Future studies for this project include the derivation of activity rates for area sources, improved explanations for the default fuel parameters defined in the NAPAP inventory and the development of links to data bases of economic activity.

  2. Traffic air pollution and oxidized LDL.

    Directory of Open Access Journals (Sweden)

    Lotte Jacobs

    Full Text Available BACKGROUND: Epidemiologic studies indirectly suggest that air pollution accelerates atherosclerosis. We hypothesized that individual exposure to particulate matter (PM derived from fossil fuel would correlate with plasma concentrations of oxidized low-density lipoprotein (LDL, taken as a marker of atherosclerosis. We tested this hypothesis in patients with diabetes, who are at high risk for atherosclerosis. METHODOLOGY/PRINCIPAL FINDINGS: In a cross-sectional study of non-smoking adult outpatients with diabetes we assessed individual chronic exposure to PM by measuring the area occupied by carbon in airway macrophages, collected by sputum induction and by determining the distance from the patient's residence to a major road, through geocoding. These exposure indices were regressed against plasma concentrations of oxidized LDL, von Willebrand factor and plasminogen activator inhibitor 1 (PAI-1. We could assess the carbon load of airway macrophages in 79 subjects (58 percent. Each doubling in the distance of residence from major roads was associated with a 0.027 µm(2 decrease (95% confidence interval (CI: -0.048 to -0.0051 in the carbon load of airway macrophages. Independently from other covariates, we found that each increase of 0.25 µm(2 [interquartile range (IQR] in carbon load was associated with an increase of 7.3 U/L (95% CI: 1.3 to 13.3 in plasma oxidized LDL. Each doubling in distance of residence from major roads was associated with a decrease of -2.9 U/L (95% CI: -5.2 to -0.72 in oxidized LDL. Neither the carbon load of macrophages nor the distance from residence to major roads, were associated with plasma von Willebrand factor or PAI-1. CONCLUSIONS: The observed positive association, in a susceptible group of the general population, between plasma oxidized LDL levels and either the carbon load of airway macrophages or the proximity of the subject's residence to busy roads suggests a proatherogenic effect of traffic air pollution.

  3. Air pollution and risk of lung cancer

    International Nuclear Information System (INIS)

    The pilot study among other things was intended to establish and to test a suitable sampling instrument, to develop quantification concepts in order to derive from the large amount of detailed sets of data the appropriate exposure measures, and to determine the distribution pattern of the main risk factors. The approach chosen for epidemiological screening was a case-control study covering a total each of 194 lung cancer cases, hospital controls, and population controls drawn in the Lands of North Rhine-Westfalia and northern Germany. This case-control approach proved to be feasible in principle. In particular, the sampling instrument for description of the risk factors 'occupation', 'smoker', and 'air pollution' proved to be suitable in combination with data in other potential influencing factors. The concepts chosen for a quantification of these factors yielded exposure measures appropriately reducing the large dimension of data of the questionnaire, without however completely exploiting it. The data ascertained within the framework of the pilot study allow to make a risk assessment for only two factors, namely 'smoker' and 'occupation'. For the index of the overall occupational exposure, covering contributions from exposure to asbestos, arsenic, nickel, chronium, PAH, and radionuclides, a relative risk of 1.8 was determined. The study indicated that there is a link between occupational exposure to asbestos or PAH, and the occurence of bronchial carcinoma. The pilot study did not give an answer to the question of whether air pollution contributes to the formation of bronchial carcinoma. This question will have to be solved by a more extensive study.

    Fumigation of tomato plants during the complete growth period with 0.1 ppm NO2 resulted in a gradually increasing discoloration of the plants starting from the lowest leaves on upwards. The yield of the plants was less by 8%. In a similar fumigation experiment with a concentration of 0.9 ppb HF carried out with eight varieties of freesia, the plants with the heaviest injury had almost no flowers and a much lower yield of corns. Potatoes, variety Bintje, fumigated during some hours with 0.1 ppm ethylene, showed curling up of the margins of the young leaves. In the urbanized area west of Rotterdam, epinastic symptoms on potato and carrot leaves appearing during some hours, pointed to air pollution with ethylene. In the first half of October lettuce in glasshouses was damaged; with the aid of the characteristic symptoms on Poa annua and Urtica urens it could be demonstrated that PAN (peroxyacetylnitrate) was the cause of the trouble. With regard to the second aluminum factory in the south-west of The Netherlands, starting production in 1971, preliminary measurements of HF pollution have been carried out. The other aluminium factory in the northeastern part of The Netherlands, caused no damage to the agricultural crops in the surroundings of the plant. From the flower bulbs cultivated in the environment of the steel factory, west of Amsterdam the gladiolus plants showed increased HF injury on the leaves, probably as a consequence of application of a new method in steel production.

    Fast-track programs to plant millions of trees in cities around the world aim at the reduction of summer temperatures, increase carbon storage, storm water control, provision of space for recreation, as well as poverty alleviation. Although these multiple benefits speak positively for urban greening programs, the programs do not take into account how close human and natural systems are coupled in urban areas. Elevated temperatures together with anthropogenic emissions of air and water pollutants distinguish the urban system. Urban and sub-urban vegetation responds to ambient changes and reacts with pollutants. Neglecting the existence of this coupling may lead to unforeseen drawbacks of urban greening programs. The potential for emissions from urban vegetation combined with anthropogenic emissions to produce ozone has long been recognized. This potential increases under rising temperatures. Here we investigate how global change induced heat waves affect emissions of volatile organic compounds (VOC) from urban vegetation and corresponding ground-level ozone levels. We also quantify other ecosystem services provided by urban vegetation (e.g., cooling and carbon storage) and their sensitivity to climate change. In this study we use Weather Research and Forecasting Model with coupled atmospheric chemistry (WRF-CHEM) to quantify these feedbacks in Berlin, Germany during the heat waves in 2003 and 2006. We highlight the importance of the vegetation for urban areas under changing climate and discuss associated tradeoffs.

    Individual air pollutants cause acute and chronic plant injury, act on stomata and affect carbon dioxide exchange as well as plant growth and development. Inhibition of photosynthesis by several air pollutants has been reported repeatedly. Besides, structural modifications of cell organelles have been reported after fumigation by SO/sub 2/. Although chlorosis and subsequent necrosis are common phenomena caused by artificial treatment with pollutants, fine structural leaf characteristics of plants exposed to long-term air pollution in natural conditions are little explored. Light microscope examination of air pollution affected leaves of plants common in natural ecosystems of Athens' metropolitan area revealed chlorosis phenomena. Electron microscope examination of the leaves of a common subshrub of greek phryganic formations grown in a heavily air polluted natural ecosystem of Athens metropolitan area revealed pronounced ultrastructural anomalies of chloroplasts, mitochondria and microbodies of the mesophyll cells. This organelle destruction of the photosynthesizing tissue as well as the minimization of the ecosystem primary productivity are attributed to the compound action of several toxic air pollutants of the photochemical smog of Athens. This work describes the long-term air pollution effects on the structural features of the leaves of Citrus aurantium, a decorative species planted throughout the heavily air polluted city of Athens.

    Indoor air concentrations of volatile organic compounds often exceed outdoor levels by a factor of 5. There is much interest in developing new technologies in order to improve indoor air quality. In this work non-thermal plasma (DC positive corona discharge) is explored as an innovative technology for indoor air purification. An inlet gas stream of 10 l min(-1) containing 0.50+/-0.02 ppm toluene was treated by the plasma reactor in atmospheric conditions. Toluene removal proved to be achievable with a characteristic energy density epsilon(0) of 50 J l(-1). Removal efficiencies were higher for 26% relative humidity (epsilon(0)=35 J l(-1)), compared with those at increased humidities (50% relative humidity, epsilon(0)=49 J l(-1)). Reaction products such as formic acid, benzaldehyde, benzyl alcohol, 3-methyl-4-nitrophenol, 4-methyl-2-nitrophenol, 4-methyl-2-propyl furan, 5-methyl-2-nitrophenol, 4-nitrophenol, 2-methyl-4,6-dinitrophenol are identified by means of mass spectrometry. Based on these by-products a toluene degradation mechanism is proposed. PMID:17490711

  10. Can the Air Pollution Index be used to communicate the health risks of air pollution?

    International Nuclear Information System (INIS)

    The validity of using the Air Pollution Index (API) to assess health impacts of air pollution and potential modification by individual characteristics on air pollution effects remain uncertain. We applied distributed lag non-linear models (DLNMs) to assess associations of daily API, specific pollution indices for PM10, SO2, NO2 and the weighted combined API (APIw) with mortality during 2003–2011 in Guangzhou, China. An increase of 10 in API was associated with a 0.88% (95% confidence interval (CI): 0.50, 1.27%) increase of non-accidental mortality at lag 0–2 days. Harvesting effects appeared after 2 days’ exposure. The effect estimate of API over lag 0–15 days was statistically significant and similar with those of pollutant-specific indices and APIw. Stronger associations between API and mortality were observed in the elderly, females and residents with low educational attainment. In conclusion, the API can be used to communicate health risks of air pollution. - Highlights: • The cumulative effects of API on mortality over lag 0–15 days remained significant. • The indices for three specific pollutants had similar associations with mortality. • The effects of API were modified by age, gender and educational attainment. • Our findings can help to communicate health risks of air pollution to the public. - The Air Pollution Index communicates health risks of air pollution

    In response to growing environmental concerns reflected in the 1990 Clean Air Act Amendment (CAAA), the United States Department of Energy (DOE) sponsored several research and development projects in late 1995 as part of an initiative entitled Advanced Environmental Control Technologies for Coal-Based Power Systems. The program provided cost-shared support for research and development projects that could accelerate the commercialization of affordable, high-efficiency, low-emission, coal-fueled electric generating technologies. Clean coal technologies developed under this program would serve as prototypes for later generations of technologies to be implemented in the industrial sector. In order to identify technologies with the greatest potential for commercial implementation, projects funded under Phase I of this program were subject to competitive review by DOE before being considered for continuation funding under Phase II. One of the primary topical areas identified under the DOE initiative relates to the development of improved technologies for reducing the emissions of air toxics. Previous studies have suggested that many of the potentially hazardous air pollutant precursors (HAPPs) occur as trace elements in the mineral matter of run-of-mine coals. As a result, these elements have the potential to be removed prior to combustion at the mine site by physical coal cleaning processes (i.e., coal preparation). Unfortunately, existing coal preparation plants are generally limited in their ability to remove HAPPs due to incomplete liberation of the mineral matter and high organic associations of some trace elements. In addition, existing physical coal cleaning plants are not specifically designed or optimized to ensure that high trace element rejections may be achieved.

    The European Concerted Action on Air Pollution Epidemiology was started in 1990 with the aim of bringing together European researchers in the field and improving research through collaboration and by preparing documents which would help to this end and by organizing workshops. A further aim was to stimulate cooperative research. Air pollution epidemiology investigates human effects of community air pollution by epidemiological methods. Epidemiology in general investigates the distribution and determinants of health-related states and events in populations. Diseases in which air pollution may play a significant role are mainly diseases of the respiratory system, for example chronic non-specific lung disease and lung cancer. Most diseases caused by air pollution can also be caused by other factors. Air pollution epidemiology is therefore specific in the expo variable (community air pollution) rather than in the type of health effects being studied. Air pollution epidemiology is beset with some specially challenging difficulties: ubiquitous exposure and as a consequence limited heterogeneity in exposure, low relative risks, few or specific health end points, and strong confounding. Further on the exposure-effect relationship is complicated by assumptions inherent to different study designs which relate to the exposure duration necessary to produce a certain health effect. In reports and workshops the concerted action tries to propose strategies to deal with these problems. (author)

    This paper examines the significant differences in seasonal variations of criteria pollutant concentrations in various parts of a large urban area. These differences are caused by the microclimatic heterogeneity of the city and show the influence of breeze and orographic-type circulations on urban air pollution. The temperature heterogeneity of Krasnoyarsk territory during the winter leads to an increase of 150% in CO air pollution levels in the central part of city. During the summer the orographical heterogeneity of Krasnoyarsk City leads to increases of up to 400% in air pollution for different areas. PMID:18330715

    2014-02-01

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

    2010-03-01

    Full Text Available The association between ambient air pollution exposure and hospitalization for cardiovascular events has been reported in several studies with conflicting results. A case-crossover design was used to investigate the effects of air pollution in 660 first-time myocardial infarction cases in Stockholm in 1993–1994, interviewed shortly after diagnosis using a standard protocol. Air pollution data came from central urban background monitors. No associations were observed between the risk for onset of myocardial infarction and two-hour or 24-hour air pollution exposure. No evidence of susceptible subgroups was found. This study provides no support that moderately elevated air pollution levels trigger first-time myocardial infarction.

  13. Ambient air pollution and allergic diseases in children

    Directory of Open Access Journals (Sweden)

    Byoung-Ju Kim

    2012-06-01

    Full Text Available The prevalence of allergic diseases has increased worldwide, a phenomenon that can be largely attributed to environmental effects. Among environmental factors, air pollution due to traffic is thought to be a major threat to childhood health. Residing near busy roadways is associated with increased asthma hospitalization, decreased lung function, and increased prevalence and severity of wheezing and allergic rhinitis. Recently, prospective cohort studies using more accurate measurements of individual exposure to air pollution have been conducted and have provided definitive evidence of the impact of air pollution on allergic diseases. Particulate matter and groundlevel ozone are the most frequent air pollutants that cause harmful effects, and the mechanisms underlying these effects may be related to oxidative stress. The reactive oxidative species produced in response to air pollutants can overwhelm the redox system and damage the cell wall, lipids, proteins, and DNA, leading to airway inflammation and hyper-reactivity. Pollutants may also cause harmful effects via epigenetic mechanisms, which control the expression of genes without changing the DNA sequence itself. These mechanisms are likely to be a target for the prevention of allergies. Further studies are necessary to identify children at risk and understand how these mechanisms regulate gene-environment interactions. This review provides an update of the current understanding on the impact of air pollution on allergic diseases in children and facilitates the integration of issues regarding air pollution and allergies into pediatric practices, with the goal of improving pediatric health.

    ObjectivesTo describe the degree of annoyance caused by air pollution and noise in pregnant women in a birth cohort; to determine the modifying factors and their relation with exposure to ambient nitrogen dioxide (NO 2). MethodsThe study population was 855 pregnant women in Valencia, Spain. Annoyance caused by air pollution and noise, and explanatory factors were obtained from 786 pregnant women through a questionnaire. NO 2 levels were determined combining measurements at 93 points within the area of study and using geostatistical techniques (kriging). ResultsIn all 7.9% of the women reported high annoyance caused by air pollution and 13.1% high annoyance caused by noise. There was a significant difference in the degree of annoyance due to both air pollution and noise depending on the area where the women lived and their working status. The degree of annoyance correlated better with measured NO 2 at the municipality level (air pollution: r=0.53; noise: r=0.44) than at the individual level (air pollution and noise: r=0.21). On multivariate analysis, being a housewife, higher NO 2 levels and high traffic density were associated with higher degrees of annoyance. ConclusionsThere was a high percentage of women who perceived medium-high annoyance due to noise and air pollution. Annoyance caused by environmental pollutants could lead to some psychological effects, which impair the quality of life, or even physiological ones, which affect prenatal development.

  18. Assessment of the Atmospheric Suspended Particles Pollution in the Madrid Air Quality Networks

    International Nuclear Information System (INIS)

    Suspended particles are a very complex type of atmospheric pollution because of their chemical composition and size. In fact, there are a quite high number of particles sources which are linked to different physicochemical processes that determine their size. At present particles smaller than 10 μm are considered the most dangerous, as has been recently pointed out by numerous epidemiologic studies. In this way, more restrictive concentration limit values have been approved in the EU countries, so an assessment of present airborne concentration values and the sources apportionment in their most representative areas is needed. In the Madrid Community a first approaching of these and other aims, has been carried out from an analysis of the Madrid Air Quality networks data. This will contribute to the establishment of concentration levels abatement strategies. (Author) 111 refs

  19. A technical overview of air pollution problems and its control

    International Nuclear Information System (INIS)

    Air pollution is a well known phenomenon experienced in every day life. The air we breathe consist of gases and aerosol particles on which pollutants such as toxic elements and bacteria reside. These microscopic particles are transported to long distances from the source of origin the direction and magnitude of which depends upon the prevailing meteorological conditions. In order to assess the impact of air pollution, systematic studies are carried out which consist of: 1) sampling of air, 2) measurement of pollutants, 3) identification of pollutant source and 4) adoption of control methods. Each of these topics are fairly exhaustive and their understanding requires accurate scientific approach. An overview of these topic has been presented in this talk. Air samples are best collected by filtering air through suitable medium and analyses are carried out by diverse analytical techniques. Source identifications is a very important step which is done either by emission modeling or receptor modeling techniques. A general survey of these techniques, especially receptor modeling is presented in this talk. The control of air pollution is carried out by using carried devices and the processes especially developed for this purpose. Air pollution has given rise to a number of global problems such as depletion of stratospheric ozone, acid rain and greenhouse effect, which are being tackled on international scale. These problems have been discussed very briefly and a summary of international efforts has been presented. (author)

    This paper examines the effect of emission taxes on pollution abatement and social welfare, when abatement goods and services are provided by a Cournot oligopoly with free-entry. We point out initially that a higher tax not only increases demand for abatement; it also makes polluters less sensitive to price. This attracts a larger number of abatement suppliers while possibly inducing each one of them to produce less. Total abatement always goes up, however, when the delivery of abatement goods and services exhibits decreasing returns to scale. We then calculate the welfare-maximizing emission tax and compare it to the Pigouvian tax. (author)

  4. The nitrogen abatement cost in wetlands

    International Nuclear Information System (INIS)

    The costs of abating agricultural nitrogen pollution in wetlands are estimated. By linking costs for construction of wetlands to the denitrification capacity of wetlands, an abatement cost function can be formed. A construction-cost function and a denitrification function for wetlands is estimated empirically. This paper establishes a link between abatement costs and the nitrogen load on wetlands. Since abatement costs fluctuate with nitrogen load, ignoring this link results in incorrect estimates of abatement costs. The results demonstrate that wetlands have the capacity to provide low cost abatement of nitrogen compounds in runoff. For the Kattegatt region in Sweden, marginal abatement costs for wetlands are shown to be lower than costs of land use changing measures, such as extended land under fallow or cultivation of fuel woods, but higher than the marginal costs of reducing nitrogen fertilizer

    To investigate damage to irises in the field resembling injury by HF, fumigations with HF were carried out. Four varieties were compared. It appeared that iris was very sensitive for HF. Differences in sensitivity between the varieties were found. To find differences in SO/sub 2/-sensitivity between varieties of lettuce several SO/sub 2/-fumigations have been carried out. More attention has to be paid to growth and fumigation conditions of the plants, because both influence the sensitivity of the varieties to SO/sub 2/. SO/sub 2/-fumigation of tomato plants grown in an atmosphere with a high humidity resulted in injuries to the leaves. Plants fumigated in the same manner and grown under restricted water supply did not show any damage. Symptoms of ozone damage to tobacco plants used as indicator plants for air pollution on trial plots occurred in July in a highly industrialized area. In the same area smog injury to several crops appeared in the open as well as in glasshouses in October. Damage to plants occurred in the vicinity of several factories. In these cases chlorine, zinc oxide, sulphur dioxide or hydrogen fluoride appeared to be the agents causing damage.

  6. A Novel Approach for Indoor Outdoor Air Pollution Monitoring

    2012-07-01

    Full Text Available Current increase of atmospheric air pollution rates in developing and developed countries requires efforts to design more cost effective and affordable devices. In developed countries pollution monitoring chambers are available to aid the monitoring process. The culture and the society are aware of the polluted environment side effects and measures have been taken to reduce pollution amounts. Most developing countries lack these chambers and they do not have cost effective tools for measuring pollution amounts for indoor and outdoor environments. Here, an effort has been made to modify low cost available pollution devices to work for indoor and outdoor pollution monitoring and a simple cost effective approach has been carried out. Indoor carbon monoxide gas level monitoring using cheap alarms sensor, supported by a car oxygen sensor for oxygen gas level monitoring. The same approach is used for outdoor gas pollution monitoring. A computer program has been designed to facilitate computer based monitoring process and logging of pollution data.

  7. Mixed deterministic statistical modelling of regional ozone air pollution

    KAUST Repository

    Kalenderski, Stoitchko Dimitrov

    2011-03-17

    We develop a physically motivated statistical model for regional ozone air pollution by separating the ground-level pollutant concentration field into three components, namely: transport, local production and large-scale mean trend mostly dominated by emission rates. The model is novel in the field of environmental spatial statistics in that it is a combined deterministic-statistical model, which gives a new perspective to the modelling of air pollution. The model is presented in a Bayesian hierarchical formalism, and explicitly accounts for advection of pollutants, using the advection equation. We apply the model to a specific case of regional ozone pollution-the Lower Fraser valley of British Columbia, Canada. As a predictive tool, we demonstrate that the model vastly outperforms existing, simpler modelling approaches. Our study highlights the importance of simultaneously considering different aspects of an air pollution problem as well as taking into account the physical bases that govern the processes of interest. © 2011 John Wiley & Sons, Ltd..

    1995-12-31

    The Hong Kong Environmental Protection Department (EPD) is currently operating an air quality monitoring network in the territory. There are nine monitoring stations, each with air quality monitoring equipment, meteorological instruments and a data logger. Five minute averaged data are transmitted through telephone lines to the central computer at the EPD Air Laboratory and are also stored in the data logger on site, as backup. At present, the EPD releases its air quality measurements to the public via monthly and special press releases, and annual reports. However, as public awareness of air pollution problems has increased, there has been an urgent need for timely and simpler information about air pollution levels. The development and operation of an Air Pollution Index (API) system has addressed that need. This presentation discusses the API computation, the information and advice released to the general public and how they can access the API information. Some API results are also presented. (author)

  11. Long-term Changes in Extreme Air Pollution Meteorology and the Implications for Air Quality

    2016-03-01

    Extreme air pollution meteorological events, such as heat waves, temperature inversions and atmospheric stagnation episodes, can significantly affect air quality. Based on observational data, we have analyzed the long-term evolution of extreme air pollution meteorology on the global scale and their potential impacts on air quality, especially the high pollution episodes. We have identified significant increasing trends for the occurrences of extreme air pollution meteorological events in the past six decades, especially over the continental regions. Statistical analysis combining air quality data and meteorological data further indicates strong sensitivities of air quality (including both average air pollutant concentrations and high pollution episodes) to extreme meteorological events. For example, we find that in the United States the probability of severe ozone pollution when there are heat waves could be up to seven times of the average probability during summertime, while temperature inversions in wintertime could enhance the probability of severe particulate matter pollution by more than a factor of two. We have also identified significant seasonal and spatial variations in the sensitivity of air quality to extreme air pollution meteorology.

    2010-01-01

    Sensor networks are currently an active research area mainly due to the potential of their applications. In this paper we investigate the use of Wireless Sensor Networks (WSN) for air pollution monitoring in Mauritius. With the fast growing industrial activities on the island, the problem of air pollution is becoming a major concern for the health of the population. We proposed an innovative system named Wireless Sensor Network Air Pollution Monitoring System (WAPMS) to monitor air pollution in Mauritius through the use of wireless sensors deployed in huge numbers around the island. The proposed system makes use of an Air Quality Index (AQI) which is presently not available in Mauritius. In order to improve the efficiency of WAPMS, we have designed and implemented a new data aggregation algorithm named Recursive Converging Quartiles (RCQ). The algorithm is used to merge data to eliminate duplicates, filter out invalid readings and summarise them into a simpler form which significantly reduce the amount of dat...

    Full Text Available This paper presents a new method for realistic real-time rendering of air pollutants based on image processing. The air pollutants’ variable density can create many shapes of mist what can add a realistic environment to virtual scene. In order to achieve a realistic effect, we further enhance thus obtained air pollution data getting from monitor in spatial domain. In the proposed method we map the densities of air pollutants to different gray levels, and visualize them by blending those gray levels with background images. The proposed method can also visualize large-scale air pollution data from different viewpoints in real-time and provide the resulting image with any resolution theoretically, which is very important and favorable for the Internet transmission.

    I study the advantages of pollution permit markets over traditional standard regulations when the regulator has incomplete information on firms? emissions and costs of production and abatement (e.g., air pollution in large cities). Because the regulator only observes each firm?s abatement technology but neither its emissions nor its output, there are cases in which standards can lead to lower emissions and, hence, welfare dominate permits. If permits are optimally combined with standards, in ...

  1. Estimating the influence of different urban canopy cover types on atmospheric particulate matter (PM10) pollution abatement in London UK.

    2010-05-01

    In the urban environment atmospheric pollution by PM10 (particulate matter with a diameter less than 10 x 10-6 m) is a problem that can have adverse effects on human health, particularly increasing rates of respiratory disease. The main contributors to atmospheric PM10 in the urban environment are road traffic, industry and power production. The urban tree canopy is a receptor for removing PM10s from the atmosphere due to the large surface areas generated by leaves and air turbulence created by the structure of the urban forest. In this context urban greening has long been known as a mechanism to contribute towards PM10 removal from the air, furthermore, tree canopy cover has a role in contributing towards a more sustainable urban environment. The work reported here has been carried out within the BRIDGE project (SustainaBle uRban plannIng Decision support accountinG for urban mEtabolism). The aim of this project is to assess the fluxes of energy, water, carbon dioxide and particulates within the urban environment and develope a DSS (Decision Support System) to aid urban planners in sustainable development. A combination of published urban canopy cover data from ground, airborne and satellite based surveys was used. For each of the 33 London boroughs the urban canopy was classified to three groups, urban woodland, street trees and garden trees and each group quantified in terms of ground cover. The total [PM10] for each borough was taken from the LAEI (London Atmospheric Emissions Inventory 2006) and the contribution to reducing [PM10] was assessed for each canopy type. Deposition to the urban canopy was assessed using the UFORE (Urban Forest Effects Model) approach. Deposition to the canopy, boundary layer height and percentage reduction of the [PM10] in the atmosphere was assessed using both hourly meterological data and [PM10] and seasonal data derived from annual models. Results from hourly and annual data were compared with measured values. The model was then

    Ambient air pollution is a known public health hazard that negatively impacts non-cutaneous organs; however, our knowledge regarding the effects on skin remains limited. Current scientific evidence suggests there are four mechanisms by which ambient air pollutants cause adverse effects on skin health: (i) generation of free radicals, (ii) induction of inflammatory cascade and subsequent impairment of skin barrier, (iii) activation of the aryl hydrocarbon receptor (AhR) and (iv) alterations to skin microflora. In this review, we provide a comprehensive overview on ambient air pollutants and their relevant sources, and highlight current evidence of the effects on skin. PMID:26289769

    These studies are conducted to compare the effects of air pollution on horse chestnut (Aesculus hippocastanum L.), London plane (Platanus acerifolia Milld.) ash-leaved maple (Acer negundo L.) and European birch (Betula alba L.). With increasing concentrations of air pollution these species react by increasing the intensity of respiration, as in separate cases the increase reaches up to 40%. Most sensitive to air pollution is the horse chestnut, followed by birch and ash-leaved maple; least sensitive is London plane. With respect to gas resistance birch and ash-leaved maple rank close to the horse chestnut but are more resistant than the horse chestnut and less sensitive than London plane.

    1976-03-01

    It is well known that the growth of buckwheat (Fagopyrum esculentum Moench) is resistant to inferior environmental conditions, but very sensitive to a polluted atmosphere. It is possible that buckwheat has favorable characteristics as phytometer for measuring air pollution. Young plants of buckwheat were grown in small cups in a water culture. Plants having three leaves were transferred to different places, both in an air polluted area and in an un-polluted area, for a period of 7 days, in order to compare the Relative Growth Rate (RGR) at their setting places. The buckwheat phytometer for measuring air pollution, utilized the following samples for statistical significance: 20 plants with 4 cups per one place according to their coefficient of variance of dry matter weight per pot. It was observed that the RGR showed the values of 20-27% per day in an un-polluted place and of 12-18% per day in a polluted place. The results of growth analysis based on dry matter increment after placement showed that the RGR depression was mainly owing to a decrease in the Net Assimilation Rate and the Leaf Area Ratio was not sensitive for a polluted atmosphere. The Net Assimilation rate depends on photosynthetic activity of leaves, therefore, the NAR depression may be due to an inhibition of photosynthesis by polluted air. 5 references, 11 figures, 8 tables.

    Under the National Ambient Air Quality Standard released in 2012 (NAAQS-2012), Beijing began to publicize hourly Air Quality Index as well as real time concentrations of 6 pollutants in its web platform to provide detailed information for air quality assessment from 2013. In this study, hourly air quality monitoring data from May 2014 to April 2015 were collected for all 35 monitoring stations in Beijing to analyze the temporal and spatial variations of air pollutants and air quality. It is found that in spatial pattern, the air qualities in southern and northern Beijing are totally different. The association between heavy pollution concentrations and wind situations suggested that neighboring area's air quality has an important role in the air quality of Beijing combining with air quality attainment rates in all 35 monitoring stations and northern China. For temporal variations, late night and early morning are the most polluted time while afternoon is the least polluted time for all pollutants except O3 with most polluted time in afternoon. Summer time in Beijing has the best air quality while winter time has the worst air quality coinciding with the heating season in the winter.

  14. The environmental policy of the EC. An analysis exemplified by air pollution abatement policy

    International Nuclear Information System (INIS)

    Since the early seventies the European Community has reacted to increasing ecological damage with complex and comprehensive common environmental policies. In this study, the author analyzes and evaluates the theoretical conception and the instrumental application of the EC Environmental Policy using four criteria: (1) Ecological effectiveness, (2) economic efficiency, (3) conformity with a market order - viewpoint of 'Ordnungspolitik', (4) 'sustainability'. The study shows that there is a large discrepancy between the demands and the reality of the EC Environmental Policy. In addition to grave ecological deficiencies it reveals an increse in rent-seeking activities and an interventionist trend which have resulted in the erosion of the competitive incentive system of the market order in the Community. In view of various deficits the author perceives a basic 'regulation paradox' and a 'policy failure'. Based on a diagnosis of the causes of these deficiencies, he outlines some proposals for a reform of the EC Environmental Policy, indicating that a central prerequisite for a more effective and efficient environmental protection is a reorientation in the system ('Ordnungspolitik') which determines the common Environmental Policy. In addition, he maintains that in view of the clear asymmetry in the representation of interests in favour of particularist interests it is necessary to strengthen public interest in order to enable a more effective protection of the options future generations will have regarding their lives and their behaviour.

    Exposure to air pollution has been linked to cardiovascular and respiratory disorders. However, the effect of air pollution on venous thrombotic disorders is uncertain. We performed a meta-analysis to assess the association between air pollution and venous thrombosis. PubMed, Embase, EBM Reviews, Healthstar, Global Health, Nursing Database, and Web of Science were searched for citations on air pollutants (carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone, and particulate matters) and venous thrombosis. Using a random-effects model, overall risk estimates were derived for each increment of 10 μg/m3 of pollutant concentration. Of the 485 in-depth reviewed studies, 8 citations, involving approximately 700,000 events, fulfilled the inclusion criteria. All the main air pollutants analyzed were not associated with an increased risk of venous thrombosis (OR = 1.005, 95% CI = 0.998–1.012 for PM2.5; OR = 0.995, 95% CI = 0.984–1.007 for PM10; OR = 1.006, 95% CI = 0.994–1.019 for NO2). Based on exposure period and thrombosis location, additional subgroup analyses provided results comparable with those of the overall analyses. There was no evidence of publication bias. Therefore, this meta analysis does not suggest the possible role of air pollution as risk factor for venous thrombosis in general population. PMID:27600652

  18. Anisotropic diffusion of volatile pollutants at air-water interface

    Li-ping CHEN

    2013-04-01

    Full Text Available The volatile pollutants that spill into natural waters cause water pollution. Air pollution arises from the water pollution because of volatilization. Mass exchange caused by turbulent fluctuation is stronger in the direction normal to the air-water interface than in other directions due to the large density difference between water and air. In order to explore the characteristics of anisotropic diffusion of the volatile pollutants at the air-water interface, the relationship between velocity gradient and mass transfer rate was established to calculate the turbulent mass diffusivity. A second-order accurate smooth transition differencing scheme (STDS was proposed to guarantee the boundedness for the flow and mass transfer at the air-water interface. Simulations and experiments were performed to study the trichloroethylene (C2HCl3 release. By comparing the anisotropic coupling diffusion model, isotropic coupling diffusion model, and non-coupling diffusion model, the features of the transport of volatile pollutants at the air-water interface were determined. The results show that the anisotropic coupling diffusion model is more accurate than the isotropic coupling diffusion model and non-coupling diffusion model. Mass transfer significantly increases with the increase of the air-water relative velocity at a low relative velocity. However, at a higher relative velocity, an increase in the relative velocity has no effect on mass transfer.

    The volatile pollutants that spill into natural waters cause water pollution. Air pollution arises from the water pollution because of volatilization. Mass exchange caused by turbulent fluctuation is stronger in the direction normal to the air-water interface than in other directions due to the large density difference between water and air. In order to explore the characteristics of anisotropic diffusion of the volatile pollutants at the air-water interface, the relationship between velocity gradient and mass transfer rate was established to calculate the turbulent mass diffusivity. A second-order accurate smooth transition differencing scheme (STDS) was proposed to guarantee the boundedness for the flow and mass transfer at the air-water interface. Simulations and experiments were performed to study the trichloroethylene (C2HCl3) release. By comparing the anisotropic coupling diffusion model, isotropic coupling diffusion model, and non-coupling diffusion model, the features of the transport of volatile pollutants at the air-water interface were determined. The results show that the anisotropic coupling diffusion model is more accurate than the isotropic coupling diffusion model and non-coupling diffusion model. Mass transfer significantly increases with the increase of the air-water relative velocity at a low relative velocity. However, at a higher relative velocity, an increase in the relative velocity has no effect on mass transfer.

  20. Effects of air pollutants on epicuticular wax chemical composition

    International Nuclear Information System (INIS)

    There are numerous reports in the literature of modifications to epicuticular wax structure as a consequence of exposure to air pollutants. Most authors have used scanning electron microscopy (SEM) to describe changes in wax crystallite morphology or distribution. ''Erosion'' or ''weathering'' of crystalline structure into an amorphous state is the most common observation, particularly in the case of conifer needles having the characteristic tube crystallites comprised of nonacosan-10-ol. Wax structure is largely determined by its chemical composition. Therefore, many of the reported changes in wax structure due to air pollutants probably arise from direct interactions between pollutants such as ozone and wax biosynthesis. The literature describing changes in wax composition due to pollutants is briefly reviewed. New evidence is introduced in support of the hypothesis for a direct interaction between air pollutants and epicuticular wax Biosynthesis. (orig.)

    This research is an analysis of various measures of ambient air pollution useful in cross-sectional epidemiological investigations and rick assessments. The Chestnut Ridge area health effects investigation, which includes a cross-sectional study of respiratory symptoms in young children, is used as a case study. Four large coal-fired electric generating power plants are the dominant pollution sources in this area of western Pennsylvania. The air pollution data base includes four years of sulfur dioxide and five years of total suspended particulate concentrations at seventeen monitors. Some 70 different characterizations of pollution are constructed and tested. These include pollutant concentrations at various percentiles and averaging times, exceedence measures which show the amount of time a specified threshold concentration is exceeded, and several dosage measures which transform non-linear dose-response relationships onto pollutant concentrations.

    Despite improvements in air quality in developed countries, air pollution remains a major public health issue. To fully assess the health impact, we must consider that air pollution exposure has both physical and psychological effects; this latter dimension, less documented, is more difficult to measure and subjective indicators constitute an appropriate alternative. In this context, this work presents the methodological development of a new scale to measure the perception of air quality, useful as an exposure or risk appraisal metric in public health contexts. On the basis of the responses from 2,522 subjects in eight French cities, psychometric methods are used to construct the scale from 22 items that assess risk perception (anxiety about health and quality of life) and the extent to which air pollution is a nuisance (sensorial perception and symptoms). The scale is robust, reproducible, and discriminates between subpopulations more susceptible to poor air pollution perception. The individual risk factors of poor air pollution perception are coherent with those findings in the risk perception literature. Perception of air pollution by the general public is a key issue in the development of comprehensive risk assessment studies as well as in air pollution risk management and policy. This study offers a useful new tool to measure such efforts and to help set priorities for air quality improvements in combination with air quality measurements. PMID:22852801

  5. Characterization of the particulate air pollution in contrasted mega cities

    International Nuclear Information System (INIS)

    This work aims at characterizing the physics and the chemistry that govern particulate air pollution in two mega cities (Paris and Cairo) for which the size distribution and the chemical composition of airborne particles were poorly documented. Seasonal variations of the main aerosol sources and transformation processes are investigated in these two urban centres, with a particular attention to semi-volatile material and secondary organic aerosols. Short-term health effects of Paris size-segregated aerosols, as well as particulate pollution during the Cairo 'Black Cloud' season, are also emphasized here. Finally, the comparison of results obtained for the two mega cities and for another one (Beijing) allows investigating main factors responsible for particulate air pollution in urban centres with contrasted climatic conditions and development levels. Notably, this work also allows the build-up of an experimental dataset which is now available for the modelling of urban air quality and of environmental impacts of mega city air pollution. (author)

  7. Public health implications of urban air pollution in developing countries

    Energy Technology Data Exchange (ETDEWEB)

    Schwela, D.H. [World Health Organisation, Geneva (Switzerland)

    1995-12-31

    Exposure to air pollution is an almost inescapable part of urban life throughout the world. Ambient air pollutant levels in urban areas are generally a reflection of emissions. For sulphur dioxide, total suspended particulate matter and lead, ambient concentrations are declining in the industrialized western countries. For nitrogen dioxide, ambient levels in cities are generally constant, or slightly increasing. For carbon dioxide, they are variable, declining where controls are being applied. In a substantial number of cities, particularly in developing countries, WHO guidelines are being often exceeded for the compounds mentioned. Given the rate at which these cities are growing, the air pollution situation will probably worsen if environmental control measures are not implemented. As a consequence, the health and well-being of urban residents will further deteriorate with high ambient air pollutant concentrations causing increased mortality, morbidity, deficits on pulmonary functions and cardiovascular and neurobehavioural effects.

  12. Evaluation of some air pollution indicators in Turkey

    International Nuclear Information System (INIS)

    This article intends to shed a light on air quality in Turkey and compare air pollutant emissions on a national scale with that of the European countries. In order to estimate the quantities of Turkish emissions in the past and their future predictions, a national emission inventory was prepared with respect to five major pollutants consisting of particulate matter(PM), SOx, NOx, non-methane volatile organic compounds, and CO with 5-year intervals between 1985 and 2005. The results suggest that Turkey is a rather large emission source at the European scale, although emission indicators on unit area and per capita were shown to be somewhat smaller in magnitude. Levels of air pollution in some of the big cities in Turkey were also evaluated from available national monitoring data. These evaluations for the urban air qualities covered SO2 and PM parameters between 1986 and 1996, and results were compared with the present Turkish air quality limits, their probable revisions, WHO (Europe) guidelines and related EC directives. Results showed that the air quality limits were not met, especially during the winter periods in Turkish cities. Urban air pollutants characterizing the air in Turkish cities other than SO2 and PM, however, could not have been evaluated as these pollutants were not systematically monitored in these cities.

  13. Air pollution episodes associated with East Asian winter monsoons

    International Nuclear Information System (INIS)

    A dozen multi-day pollution episodes occur from October to February in Hanoi, Vietnam due to prolonged anticyclonic conditions established after the northeast monsoon surges (cold surges). These winter pollution episodes (WPEs) account for most of the 24-h PM10 exceedances and the highest concentrations of gaseous pollutants in Hanoi. In this study, WPEs were investigated using continuous air quality monitoring data and information on upper-air soundings and air mass trajectories. The 24-h pollutant concentrations are lowest during cold surges; concurrently rise thereafter reaching the highest levels toward the middle of a monsoon cycle, then decline ahead of the next cold surge. Each monsoon cycle usually proceeds through a dry phase and a humid phase as Asiatic continental cold air arrives in Hanoi through inland China then via the East China Sea. WPEs are associated with nighttime radiation temperature inversions (NRTIs) in the dry phase and subsidence temperature inversions (STIs) in the humid phase. In NRTI periods, the rush hour pollution peak is more pronounced in the evening than in the morning and the pollution level is about two times higher at night than in daytime. In STI periods, broad morning and evening traffic peaks are observed and pollution is as high at night as in daytime. The close association between pollution and winter monsoon meteorology found in this study for the winter 2003-04 may serve as a basis for advance warning of WPEs and for forecasting the 24-h pollutant concentrations. - Highlights: → Dozen pollution episodes from Oct. to Feb in Hanoi associated with anticyclones after monsoon surges. → 24-h concentrations of PM10, SO2, NO2, CO rise after surge and decline ahead of the next. → Episodes caused by nighttime radiation and subsidence inversions in dry and humid monsoon phases. → Distinct diurnal variations of pollutant concentrations observed in the two periods. → Close pollution-meteorology association serve as a basis

    An air pollution model is generally described by a system of PDEs on unbounded domain. Transformation of the independent variable is used to convert the problem for nonlinear air pollution on finite computational domain. We investigate the new, degenerated parabolic problem in Sobolev spaces with weights for well-posedness and positivity of the solution. Then we construct a fitted finite volume difference scheme. Some results from computations are presented.

  12. Australians are not equally protected from industrial air pollution

    International Nuclear Information System (INIS)

    Australian air pollution standards are set at national and state levels for a number of chemicals harmful to human health. However, these standards do not need to be met when ad hoc pollution licences are issued by state environment agencies. This situation results in a highly unequal distribution of air pollution between towns and cities, and across the country. This paper examines these pollution regulations through two case studies, specifically considering the ability of the regulatory regime to protect human health from lead and sulphur dioxide pollution in the communities located around smelters. It also considers how the proposed National Clean Air Agreement, once enacted, might serve to reduce this pollution equity problem. Through the case studies we show that there are at least three discrete concerns relating to the current licencing system. They are: non-onerous emission thresholds for polluting industry; temporal averaging thresholds masking emission spikes; and ineffective penalties for breaching licence agreements. In conclusion, we propose a set of new, legally-binding national minimum standards for industrial air pollutants must be developed and enforced, which can only be modified by more (not less) stringent state licence arrangements.

  13. Low-level coal combustion as an important problem related to air pollution in Silesia

    International Nuclear Information System (INIS)

    Statistical analyses of pollutants from the Katowice District for many years have attributed to the poor air quality to industrial emission sources. Among the source categories for which pollutant emissions into the atmosphere have not been recognized in detail so far, municipal heat sources are worth mentioning. These sources include local boiler houses, residual space heating plants, and individual ceramic furnaces. The problem was investigated by the Institute of Environmental Protection in cooperation with the Regional Design Office at Zabrze. The inventory covered three heat sources: (1) local boiler houses, (2) individual furnaces in multiple-family houses, and (3) individual ceramic furnaces in private houses. For each administrative unit within the district, concentration levels for boiler house and individual household furnaces have been calculated for both local sources and external sources. the calculations have shown that more than 80% of the local concentration levels come from individual furnaces. It also has been found that emissions within a given administrative unit are considerably affected by similar source types in the neighboring units. This relationship has been used to evaluate the administrative units in the Katowice District. In light of the analyses performed, the general conclusion can be drawn the improvement in the sanitary quality of the air depends not only on local emission abatement, but also on integrated activity within the heat and gas supply for old flats and individual private house in the Katowice District

  14. Air pollution and forest ecosystems: a regional to global perspective

    International Nuclear Information System (INIS)

    Changes in the atmospheric concentrations of a number of air pollutants over the last century are hallmarks of the magnitude and extent of human impact on the environment. Some of these changes are important to ecologists because many pollutants, acting singly or in combination, affect ecological systems in general and forests in particular. The greatest concern lies with chronic levels of tropospheric ozone, cumulative deposition of hydrogen ion, nitrogen, and sulfur via wet and dry processes, a select number of airborne chemicals (e.g., mercury) that tend to bio accumulate in continental landscapes, and ultraviolet—B radiation through the loss of stratospheric ozone. Because the atmospheric residence time of most pollutants of concern to ecologists is measured on time frames extending from a few weeks to decades, pollutant distribution and effects are regional to global in dimension. We present evidence that ambient levels of some air pollutants in North America are affecting managed and unmanaged forests, and that the two most important pollutants are tropospheric ozone and chronic nitrogen loading. Further evidence indicates that while concentrations of some air pollutants have been declining over the last decade in North America, others are expected to remain unchanged or increase, including tropospheric ozone. We conclude that air pollution is affecting many North American forests and some remote forests around the globe. In the immediate future, the concern for air pollution effects on forests and associated natural resources will broaden to include interactions with changes in climate and pollution effects in the world's developing countries. There has been a rapid evolution in air pollution studies in ecology, shifting away from the agricultural paradigm of single—factor experimentation toward new methodologies that are ecologically and multidisciplinarily based. This shift has been promoted by the recognition that air pollution is one of several

    2014-12-01

    Air pollution not only has long term health impact, but can affect health through acute exposure. This paper, using air pollution index (API) as overall evaluation of air quality, blood pressure and vital capacity as health outcomes, focuses on the acute health impact of air pollution in China. Current result suggests that after controlling smoking history, occupational exposure, income and education, API is positively associated with blood pressure and negatively associated with vital capacity. The associations became stronger for people with hypertension or pulmonary functional diseases, which indicates that these people are more sensitive to air pollution. Among three pollutants which API measures, that is inhalable particles (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NO2), PM10 is most statistically associated with blood pressure increase and vital capacity decrease. Further study will focusing on the following two questions. The first question is how various time lags affect the associations among API, blood pressure and vital capacity. The second question is how differently people in various cohorts reacts to acute exposure to air pollution. The differences in reactions of blood pressure and vital capacity between people in urban and rural areas, genders, various age cohorts, distinct income and education groups will be further studied.

The study is based on primary sources of data collected with the help of questionnaire interviews from a sample of 2,101 women respondents belonging from different income groups, from Aligarh city. Information regarding their cooking conditions (4 factors, cooking related exposures (4 factors, housing (3 factors and health conditions (3 factors were collected. Total 14 factors linked with women vulnerability to indoor air pollution were identified. Indoor air pollutants were monitored in the cooking area and with different fuel usages to assess the indoor air quality. The results show that women are vulnerable to indoor air pollution but there was difference in the levels of vulnerability among the women belonging to different income groups. It was the lower income women who were most vulnerable because they were using biomass fuels/chulhas, cooking in a multipurpose room, spending long hours in kitchen, they were more exposed to smoke, heat, pollutants and the conditions were exacerbated because they were living in sub-standard housing, in one room leading to congestion/crowding and with no ventilation. They were suffering most from various problems and specific diseases like respiratory infections (ALRI, AURI, COPD, asthma, pulmonary tuberculosis, perinatal mortality, low birth weight, cataract and eye irritation associated with indoor air pollution.

    2015-06-01

    Full Text Available The issue of air quality conditions and atmospheric pollution in the Arab Region has been addressed through consideration of the energy production and energy consumption pattern. Global, regional and local sources of air pollution in the study have been considered. Emission scenarios of many Arab countries of the region have been outli ned. It has been realized that air pollution constitutes one of the major sources of loss on GNP of many Arab countries in the region due to weak institutional capabilities for air pollution management and control. Major types of air pollution sources in t he region such as greenhouse gas emissions and other gases from various industries are considered. Local sources of air pollution are found due to urban growth, transportation systems, industrialization and lack of awareness and shortage of institutional c apabilities all contributed to the relatively low air quality and weak control in the Arab Region. The purpose of this paper is to review all available literature on the issue of air pollution in Arab countries due to combustion of fossil fuel coming from mobile sources and petroleum gas flaring in order to present the dire situation of the air quality in Arab countries. The report is organized based on certain factors which make the transport sector , power plants and associated gas flaring are significan t polluters of the air in the Arab region. We present a brief introduction to the composition of the transport sector in most of Arab countries and the forms of emissions resulting from it, then the report continues with the explanation of the major impact s that old - aged machines like automobiles, old petroleum production technology and old electrical energy plants technology have in terms of causing air pollution in these countries and thus; making them very inefficient and also very harmful towards the en vironment in most of Arab countries. In this paper also we have used the statistical data during

  3. Good manufacturing practice for modelling air pollution: Quality criteria for computer models to calculate air pollution

    Science.gov (United States)

    Dekker, C. M.; Sliggers, C. J.

    To spur on quality assurance for models that calculate air pollution, quality criteria for such models have been formulated. By satisfying these criteria the developers of these models and producers of the software packages in this field can assure and account for the quality of their products. In this way critics and users of such (computer) models can gain a clear understanding of the quality of the model. Quality criteria have been formulated for the development of mathematical models, for their programming—including user-friendliness, and for the after-sales service, which is part of the distribution of such software packages. The criteria have been introduced into national and international frameworks to obtain standardization.

  4. Photochemical and other air pollutants in the Netherlands

    1976-01-01

    In 1975, together with the State Institute of Public Health and the Royal Dutch Meteorological Institute, The Institute of Phytopathological Research continued investigations on incidence of air pollution throughout the Netherlands. Culture vessels with indicator plants were placed on 31 test plots of the National Air Pollution Monitoring Network. During the growing season from May until October, the indicator plants were inspected weekly for typical symptoms of air pollution. Until July, photochemical air pollution by ozone caused less injury to Spinacia oleracea than in the preceding year. On Nicotiana tabacum there was as much injury as in 1974, especially in the 33rd, 36th and 37th week, all over the country. An increasing number of injurious effects by peroxyacetyl nitrate was observed on Petunia nyctaginiflora, Poa annua and Urtica urens. Medicago sativa, Fagopyrum esculentuma nd Petunia nyctaginiflora, indicator plants for the pollutants SO2, NO/sub x/ and ethylene, showed little and Solanum tuberosum, possible indicator plant for ethylene and ozone, no injury in 1975. Finally air pollution by HG occurred on the same scale as in 1974, as shown by Tulipa gesneriana in spring and Gladiolus gandavensis in summer. These results corresponded with the figures for F from the limed paper method. As in 1974, data on injury to the plants and from the limed paper method showed a decline from south to north.

  6. A mathematical formulation for optimal control of air pollution

    Institute of Scientific and Technical Information of China (English)

    朱江; 曾庆存

    2003-01-01

    The problem of optimal control of air pollution using weather forecastresults and numerical air pollution models is discussed. A mathematical formulation of the problem is presented. The control is an act on pollution sources with feasible constraints. Based on forecasted weather conditions, the objective ofthe optimal control is to minimize total cost caused by control under the constraint that the pollution concentrations over a certain period and a certain spatial domain are less than some specified values. Using the adjoint method, an effective algorithm is given. Since the optimal solutions are based on weather forecasts, the errors in weather forecasts will cause uncertainties in the optimal solutions. Estimation of impacts of weather forecast errors on the optimal solutions is discussed using the adjoint sensitivity analysis technique that is an approximated, however very effective method. The adjoint sensitivity analysis technique can be used to calculate the impacts of errors in wind, temperature and initial pollutant concentration fields on performances of the optimal control.

  11. Hold your breath: A new index of air pollution

    International Nuclear Information System (INIS)

    Environmental quality and climate change have been discussed prominently as urgent problems that – due to air pollution – produce severe consequences affecting the everyday life of millions of people. Using a Multiple Indicators Multiple Causes (MIMIC) model, we calculate a new index of air pollution and provide a ranking for 122 countries for every fifth year between 1985 and 2005. The empirical analysis supports the Environmental Kuznets Curve (EKC) hypothesis and shows a significant influence of determinants such as energy efficiency, industrial production, the electricity produced from coal sources, and demographic transition on air pollution. According to the index, Norway, Switzerland, Japan, Luxembourg, and Iceland are among the top 5 countries in terms of air quality performance. Eritrea, Mozambique, Tajikistan, the Democratic Republic of Congo, and Ethiopia performed worst in 2005. - Highlights: ► We calculate a new index of air pollution and provide a ranking for 122 countries. ► The empirical analysis supports the EKC hypothesis. ► Country ranking of this air pollution index is comparable across the period 1985 to 2005. ► Definition of the underlying variables does not change and the methodology is consistent

  12. Air Pollution and Autism Spectrum Disorders: Causal or Confounded?

    2015-12-01

    In the last decade, several studies have examined the association between perinatal exposure to ambient air pollution and risk of autism spectrum disorder (ASD). These studies have largely been consistent, with associations seen with different aspects of air pollution, including hazardous air toxics, ozone, particulate, and traffic-related pollution. Confounding by socioeconomic status (SES) and place of residence are of particular concern, as these can be related to ASD case ascertainment and other potential causal risk factors for ASD. While all studies take steps to address this concern, residual confounding is difficult to rule out. Two recent studies of air pollution and ASD, however, present findings that strongly argue against residual confounding, especially for factors that do not vary over relatively short time intervals. These two studies, conducted in communities around the USA, found a specific association with air pollution exposure during the 3rd, but not the 1st, trimester, when both trimesters were modeled simultaneously. In this review, we discuss confounding possibilities and then explain-with the aid of directed acyclic graphs (DAGs)-why an association that is specific to a particular time window, when multiple exposure windows are simultaneously assessed, argues against residual confounding by (even unmeasured) non-time-varying factors. In addition, we discuss why examining ambient air pollution concentration as a proxy for personal exposure helps avoid confounding by personal behavior differences, and the implications of measurement error in using ambient concentrations as a proxy for personal exposures. Given the general consistency of findings across studies and the exposure-window-specific associations recently reported, the overall evidence for a causal association between air pollution and ASD is increasingly compelling.

    This report comprises two separate complementary parts that address the links between CCS implementation and its subsequent impacts on GHG and air pollutant emissions on a life-cycle basis: Part A discusses and presents key findings from the latest literature, focusing upon the potential air pollution impacts across the CCS life-cycle arising from the implementation of the main foreseen technologies. Both negative and positive impacts on air quality are presently suggested in the literature - the basis of scientific knowledge on these issues is rapidly advancing. Part B comprises a case study that quantifies and highlights the range of GHG and air pollutant life-cycle emissions that could occur by 2050 under a low-carbon pathway should CCS be implemented in power plants across the European Union under various hypothetical scenarios. A particular focus of the study was to quantify the main life-cycle emissions of the air pollutants taking into account the latest knowledge on air pollutant emission factors and life-cycle aspects of the CCS life-cycle as described in Part A of the report. Pollutants considered in the report were the main GHGs CO{sub 2}, methane (CH{sub 4}) and nitrous oxide (N{sub 2}O) and the main air pollutants with potential to harm human health and/or the environment - nitrogen oxides (NO{sub X}), sulphur dioxide (SO{sub 2}), ammonia (NH{sub 3}), non-methane volatile organic compounds (NMVOCs) and particulate matter (PM{sub 10}).

  14. Air pollution impacts from demand-side management

    International Nuclear Information System (INIS)

    Air-polluting emission rates and energy-efficiency ratings vary widely among power plants, depending on location, age and whether the power plant is repowered. Traditional regulations require installation of specified emission control equipment that varies among power plants. These regulations do not specify that utilities first dispatch the cleanest power plants as demand varies from peak to off-peak periods. This empirical analysis shows, for 2 years out of 20, that demand-side management (DSM) programs increase air pollution. One reason for this result is that regulations require installation of specific emission-control technology but do not provide the incentive to take actual emissions or their air quality impacts into account when operating the system. For certain types of air pollutants and in some regions, regulatory programs now include markets for tradable emission credits. Such programs may alter this incentive. (author)

    2004-01-01

    To determine the best statistical distribution of concentration data of major air pollutants in Shanghai. Methods Four types of theoretic distributions (lognormal, gamma, Pearson V and extreme value) were chosen to fit daily average concentration data of PM10, SO2 and NO2 from June 1, 2000 to May 31, 2003 in Shanghai by using the maximum likelihood method. The fit results were evaluated by Chi-square test. Results The best-fit distributions for PM10, SO2 and NO2 concentrations in Shanghai were lognormal, Pearson V, and extreme value distributions, respectively. Conclusion The results can be further applied to local air pollution prediction and control, e.g., the probabilities exceeding the air quality standard and emission source reduction of air pollutant concentration to meet the standard.

  2. Air pollutant penetration through airflow leaks into buildings

    Energy Technology Data Exchange (ETDEWEB)

    Liu, De-Ling

    2002-09-01

    The penetration of ambient air pollutants into the indoor environment is of concern owing to several factors: (1) epidemiological studies have shown a strong association between ambient fine particulate pollution and elevated risk of human mortality; (2) people spend most of their time in indoor environments; and (3) most information about air pollutant concentration is only available from ambient routine monitoring networks. A good understanding of ambient air pollutant transport from source to receptor requires knowledge about pollutant penetration across building envelopes. Therefore, it is essential to gain insight into particle penetration in infiltrating air and the factors that affect it in order to assess human exposure more accurately, and to further prevent adverse human health effects from ambient particulate pollution. In this dissertation, the understanding of air pollutant infiltration across leaks in the building envelope was advanced by performing modeling predictions as well as experimental investigations. The modeling analyses quantified the extent of airborne particle and reactive gas (e.g., ozone) penetration through building cracks and wall cavities using engineering analysis that incorporates existing information on building leakage characteristics, knowledge of pollutant transport processes, as well as pollutant-surface interactions. Particle penetration is primarily governed by particle diameter and by the smallest dimension of the building cracks. Particles of 0.1-1 {micro}m are predicted to have the highest penetration efficiency, nearly unity for crack heights of 0.25 mm or higher, assuming a pressure differential of 4 Pa or greater and a flow path length of 3 cm or less. Supermicron and ultrafine particles (less than 0.1 {micro}m) are readily deposited on crack surfaces by means of gravitational settling and Brownian diffusion, respectively. The fraction of ozone penetration through building leaks could vary widely, depending

    1989-08-01

    Rats were used as biological indicators of air quality in two heavily polluted Brazilian towns: Sao Paulo and Cubatao. They were exposed for 6 months to ambient air in areas where the pollution was known to be severe. The following parameters were studied and compared to those of control animals: respiratory mechanics, mucociliary transport, morphometry of respiratory epithelium and distal air spaces, and general morphological alterations. The results showed lesions of the distal and upper airways in rats exposed in Cubatao, whereas the animals from Sao Paulo showed only alterations of the upper airways but of greater intensity than those observed in the Cubatao group. There are both qualitative and quantitative differences in the pollutants of these places: in Sao Paulo automobile exhaust gases dominate and in Cubatao the pollution is due mainly to particulates of industrial sources. The correlation of the pathological findings with the pollutants is discussed and it is concluded that biological indicators are useful to monitor air pollutions which reached dangerous levels in Sao Paulo and Cubatao.

  4. Crop loss due to air pollution in The Netherlands.

    1988-01-01

    The extent of yield reduction and economic loss caused by air pollution has been estimated for The Netherlands. Based on available data on direct effects only, each species was designated as sensitive, moderately sensitive or tolerant. On a nationwide scale, only ozone (O3), sulphur dioxide (SO2), and hydrogen fluoride (HF) exceeded effect thresholds. Effects from pollutant combinations were assumed to be additive. Yield reductions were calculated, using 10 exposure-response relationships and concentration data from the Dutch air pollution monitoring network. Changes in air pollution levels result in changes in supply. By multiplying the supply with the current price, the so-called crop volume was calculated. Subsequently, changes in crop volume were converted into economic terms, taking into account demand elasticity. On the basis of these calculations, air pollution in The Netherlands reduces total crop volume by 5%:3.4% by O3, 1.2% by SO2, and 0.4% by HF. The slope of the nonlinear relationship between crop volume reduction and exposure level increases at higher concentrations. In general, air pollution causes relatively little loss to producers, since yield reductions are largely compensated by higher prices. If air pollution in The Netherlands would be reduced to background concentrations, consumers would experience a net gain of Dfl 640 million (US 320 million dollars). Although large amounts of data were attained through literature and our own experience for this study, many assumptions still had to be made to arrive at these conclusions. With the current available knowledge, validation of our results in the field is not yet possible. PMID:15092562

  6. Air Pollution Stress and the Aging Phenotype: The Telomere Connection.

    2016-09-01

    Aging is a complex physiological phenomenon. The question why some subjects grow old while remaining free from disease whereas others prematurely die remains largely unanswered. We focus here on the role of air pollution in biological aging. Hallmarks of aging can be grouped into three main categories: genomic instability, telomere attrition, and epigenetic alterations leading to altered mitochondrial function and cellular senescence. At birth, the initial telomere length of a person is largely determined by environmental factors. Telomere length shortens with each cell division and exposure to air pollution as well as low residential greens space exposure is associated with shorter telomere length. Recent studies show that the estimated effects of particulate air pollution exposure on the telomere mitochondrial axis of aging may play an important role in chronic health effects of air pollution. The exposome encompasses all exposures over an entire life. As telomeres can be considered as the cellular memories of exposure to oxidative stress and inflammation, telomere maintenance may be a proxy for assessing the "exposome". If telomeres are causally related to the aging phenotype and environmental air pollution is an important determinant of telomere length, this might provide new avenues for future preventive strategies.

    Full Text Available Abstract The Arctic is a sentinel of global change. This region is influenced by multiple physical and socio-economic drivers and feedbacks, impacting both the natural and human environment. Air pollution is one such driver that impacts Arctic climate change, ecosystems and health but significant uncertainties still surround quantification of these effects. Arctic air pollution includes harmful trace gases (e.g. tropospheric ozone and particles (e.g. black carbon, sulphate and toxic substances (e.g. polycyclic aromatic hydrocarbons that can be transported to the Arctic from emission sources located far outside the region, or emitted within the Arctic from activities including shipping, power production, and other industrial activities. This paper qualitatively summarizes the complex science issues motivating the creation of a new international initiative, PACES (air Pollution in the Arctic: Climate, Environment and Societies. Approaches for coordinated, international and interdisciplinary research on this topic are described with the goal to improve predictive capability via new understanding about sources, processes, feedbacks and impacts of Arctic air pollution. Overarching research actions are outlined, in which we describe our recommendations for 1 the development of trans-disciplinary approaches combining social and economic research with investigation of the chemical and physical aspects of Arctic air pollution; 2 increasing the quality and quantity of observations in the Arctic using long-term monitoring and intensive field studies, both at the surface and throughout the troposphere; and 3 developing improved predictive capability across a range of spatial and temporal scales.

  8. The Effects of Air Pollution and Temperature on COPD.

    Hansel, Nadia N; McCormack, Meredith C; Kim, Victor

    2016-06-01

    Chronic Obstructive Pulmonary Disease (COPD) affects 12-16 million people in the United States and is the third-leading cause of death. In developed countries, smoking is the greatest risk factor for the development of COPD, but other exposures also contribute to the development and progression of the disease. Several studies suggest, though are not definitive, that outdoor air pollution exposure is linked to the prevalence and incidence of COPD. Among individuals with COPD, outdoor air pollutants are associated with loss of lung function and increased respiratory symptoms. In addition, outdoor air pollutants are also associated with COPD exacerbations and mortality. There is much less evidence for the impact of indoor air on COPD, especially in developed countries in residences without biomass exposure. The limited existing data suggests that indoor particulate matter and nitrogen dioxide concentrations are linked to increased respiratory symptoms among patients with COPD. In addition, with the projected increases in temperature and extreme weather events in the context of climate change there has been increased attention to the effects of heat exposure. Extremes of temperature-both heat and cold-have been associated with increased respiratory morbidity in COPD. Some studies also suggest that temperature may modify the effect of pollution exposure and though results are not conclusive, understanding factors that may modify susceptibility to air pollution in patients with COPD is of utmost importance.

    China is the world's largest emitter of anthropogenic air pollutants, and measurable amounts of Chinese pollution are transported via the atmosphere to other countries, including the United States. However, a large fraction of Chinese emissions is due to manufacture of goods for foreign consumption. Here, we analyze the impacts of trade-related Chinese air pollutant emissions on the global atmospheric environment, linking an economic-emission analysis and atmospheric chemical transport modeling. We find that in 2006, 36% of anthropogenic sulfur dioxide, 27% of nitrogen oxides, 22% of carbon monoxide, and 17% of black carbon emitted in China were associated with production of goods for export. For each of these pollutants, about 21% of export-related Chinese emissions were attributed to China-to-US export. Atmospheric modeling shows that transport of the export-related Chinese pollution contributed 3-10% of annual mean surface sulfate concentrations and 0.5-1.5% of ozone over the western United States in 2006. This Chinese pollution also resulted in one extra day or more of noncompliance with the US ozone standard in 2006 over the Los Angeles area and many regions in the eastern United States. On a daily basis, the export-related Chinese pollution contributed, at a maximum, 12-24% of sulfate concentrations over the western United States. As the United States outsourced manufacturing to China, sulfate pollution in 2006 increased in the western United States but decreased in the eastern United States, reflecting the competing effect between enhanced transport of Chinese pollution and reduced US emissions. Our findings are relevant to international efforts to reduce transboundary air pollution. PMID:24449863

Hydrogen sulfide is a colorless gas that has an obnoxious odor at low concentrations. The odor threshold is in the g/cu m range. In higher concentrations, the gas is toxic to humans and animals and corrosive to many metals. It will tarnish silver and react with heavy metals in points to discolor the paint. In humans, it will cause headache, conjunctivitis, sleeplessness, pain in the eyes, and similar symptoms at low air concentrations and death at high air concentrations. However, the majority of the complaints arising from hydrogen sulfide air pollution are due to its obnoxious odor in extremely low air concentrations. Air pollution by hydrogen sulfide is not a widespread urban problem but is generally localized in the vicinity of an emitter such as kraft paper mills, industrial waste disposal ponds, sewage plants, refineries, and coke oven plants.

  12. Pollution. Warning on the future of air quality

    International Nuclear Information System (INIS)

    This article comments the results published by INERIS (the French national institute of the industrial environment and risks) and based on the use of its model Chimere which aims at measuring and foreseeing the evolution of air quality. This model simulates the concentrations of pollutants in the air. It is integrated into the national tool of prediction of air quality, PREV'AIR, which studies prospective scenarios of reduction of emissions, and is also part of the SALUT'AIR project which assesses the evolution of atmospheric concentrations of pollutants by 2050 while taking climate change into account. These models notably show the importance of atmospheric circulation over continents. The author also recalls and comments the objectives of the UN Goteborg protocol for 2020

    Shani, Gad; Haccoun, A.; Kushelevsky, A.

    The size distribution of aerosols was measured in a moderately industrial city, in a semi-arid zone on the Negev desert border. The aerosols in the city of Beer Sheva are from two sources: the dust coming from the desert and urban pollution. The size measurements were done with a cascade impactor. The elemental content of the aerosols was investigated by neutron activation analysis and X-ray fluorescence. The main elements of the dust are: Ca, Si, Fe, Na and the trace elements are: Sc, Se, La, Sm, Hf and others. The main elements of the urban pollution are S, Br, Pb, Cl, Hg and others. It was found that the elements belonging to each group can easily be classified by the size distribution. The analytical consideration of the aerosol size distribution of each group are discussed and two corresponding analytical expressions are suggested. It is shown that aerosols originating in the dust have a hump shape distribution around ~ 4μm, and those originating in urban pollution have a distribution decreasing with increasing aerosol diameter. Many examples are given to prove the conclusions.

    Objective: To study the mechanism of formation of air quality and to determine the impact of the studied factors on asthma morbidity in Vladivostok. Methods: The evaluation of air pollution in Vladivostok was done using long-term (2008–2012) monitoring data (temperature, humidity, atmospheric pressure, wind speed, etc.). The levels of suspended particulate matter, nitrogen and sulfur dioxide, carbon monoxide, ammonia, formaldehyde (mg/m3) in six stationary observation posts were assessed. We studied the aerosol suspensions of solid particles, which were collected during snowfall from precipitation (snow) and air in 14 districts with different levels of anthropogenic impact. Melted snow was analyzed on laser granulometry. The impact of air pollution on the distribution of asthma morbidity was evaluated in various age groups by data of federal statistical observation obtained from 8 adults and 7 children municipal clinics in Vladivostok (2008–2012). Results: The content of suspended particulate components of pollution remained more stable, due to the features of atmospheric circulation, rugged terrain and residential development. The nano- and micro-sized particles (0–50 mm), which can absorb highly toxic metals, prevail in dust aerosols. These respirable fractions of particles, even in small doses, can contribute to the increase in asthma morbidity in the city. Conclusions: We determined that asthma morbidity depends from general air pollution (in the range of 18.3%). It was detected that the highest age-specific dependence is associated with the content of particulate matter, carbon monoxide and nitrogen dioxide in air.

    Full Text Available Motor vehicles release carbon monoxide, nitrogen dioxide, sulphur dioxide, and particulate matters to the air as pollutants. Vegetation can absorb these pollutants through gas exchange processes. The objective of this study was to examine the combination of the relative growth rate (RGR and physiological responses in determining tolerance levels of plant species to air pollutants. Physiological responses were calculated as air pollution tolerance index (APTI. Eight roadside tree species were placed at polluted (Jagorawi highway and unpolluted (Sindangbarang field area. Growth and physiological parameters of the trees were recorded, including plant height, leaf area, total ascorbate, total chlorophyll, leaf-extract pH, and relative water content. Scoring criteria for the combination of RGR and APTI method was given based on means of the two areas based on two-sample t test. Based on the total score of RGR and APTI, Lagerstroemia speciosa was categorized as a tolerant species; and Pterocarpus indicus, Delonix regia, Swietenia macrophylla were categorized as moderately tolerant species. Gmelina arborea, Cinnamomum burmanii, and Mimusops elengi were categorized as intermediate tolerant species. Lagerstroemia speciosa could be potentially used as roadside tree. The combination of RGR and APTI value was better to determinate tolerance level of plant to air pollutant than merely APTI method.

    Economic growth and increased urbanization pose a new risk for cancer development: the exposure of high numbers of people to ambient air pollution. Epidemiological evidence that links air pollution to mortality from lung cancer is robust. An ability to produce high-quality scientific research that addresses these risks and the ability of local health authorities to understand and respond to these risks are basic requirements to solve the conflict between economic development and the preservation of human health. However, this is currently far from being achieved. Thus, this Science and Society article addresses the possibilities of expanding scientific networking to increase awareness of the risk of lung cancer that is promoted by air pollution. PMID:23924644
