    Full Text Available Abstract This paper aims to provide a critical and systematic review of the societal costs of air pollution-related ill health (CAP, to explore methodological issues that may be important when assessing or comparing CAP across countries and to suggest ways in which future CAP studies can be made more useful for policy analysis. The methodology includes a systematic search based on the major electronic databases and the websites of a number of major international organizations. Studies are categorized by origin – OECD countries or non-OECD countries – and by publication status. Seventeen studies are included, eight from OECD countries and nine from non-OECD countries. A number of studies based on the ExternE methodology and the USA studies conducted by the Institute of Transportation are also summarized and discussed separately. The present review shows that considerable societal costs are attributable to air pollution-related health hazards. Nevertheless, given the variations in the methodologies used to calculate the estimated costs (e.g. cost estimation methods and cost components included, and inter-country differences in demographic composition and health care systems, it is difficult to compare CAP estimates across studies and countries. To increase awareness concerning the air pollution-related burden of disease, and to build links to health policy analyses, future research efforts should be directed towards theoretically sound and comprehensive CAP estimates with use of rich data. In particular, a more explicit approach should be followed to deal with uncertainties in the estimations. Along with monetary estimates, future research should also report all physical impacts and source-specific cost estimates, and should attempt to estimate 'avoidable cost' using alternative counterfactual scenarios.

    The potential health impact of ambient ozone and PM2.5 concentrations modulated by climate change over the United States is investigated using combined atmospheric and health modeling. Regional air quality modeling for 2001 and 2050 was conducted using CMAQ Modeling System with meteorology from the GISS Global Climate Model, downscaled regionally using MM5,keeping boundary conditions of air pollutants, emission sources, population, activity levels, and pollution controls constant. BenMap was employed to estimate the air pollution health outcomes at the county, state, and national level for 2050 caused by the effect of meteorology on future ozone and PM2.5 concentrations. The changes in calculated annual mean PM2.5 concentrations show a relatively modest change with positive and negative responses (increasing PM2.5 levels across the northeastern U.S.) although average ozone levels slightly decrease across the northern sections of the U.S., and increase across the southern tier. Results suggest that climate change driven air quality-related health effects will be adversely affected in more then 2/3 of the continental U.S. Changes in health effects induced by PM2.5 dominate compared to those caused by ozone. PM2.5-induced premature mortality is about 15 times higher then that due to ozone. Nationally the analysis suggests approximately 4000 additional annual premature deaths due to climate change impacts on PM2.5 vs 300 due to climate change-induced ozone changes. However, the impacts vary spatially. Increased premature mortality due to elevated ozone concentrations will be offset by lower mortality from reductions in PM2.5 in 11 states. Uncertainties related to different emissions projections used to simulate future climate, and the uncertainties forecasting the meteorology, are large although there are potentially important unaddressed uncertainties (e.g., downscaling, speciation, interaction, exposure, and concentration-response function of the human health studies

    Climate change may affect exposures to air pollutants by affecting weather, anthropogenic emissions, and biogenic emissions and by changing the distribution and types of airborne allergens. Local temperature, precipitation, clouds, atmospheric water vapor, wind speed, and wind direction influence atmospheric chemical processes, and interactions occur between local and global-scale environments. If the climate becomes warmer and more variable, air quality is likely to be affected. However, the...

    A study was conducted to assess the air pollution burden of illness (BOI) related to air quality measurements in Toronto. BOI estimates can assess the human health risk of existing or expected levels of air pollution. New scientific literature, data and measuring methods allow for the quantification of adverse health effects associated with exposure to air pollution. The information provides numerical coefficients associating a broad range of health end points with air pollutants. The coefficients can be used to estimate the air pollution BOI in a community if the air pollution levels have been measured and if the disease specific overall BOI data from hospitals are also available. This report described the factors influencing the direction of scientific research in air pollution. It also provided a literature review of epidemiological studies. The risk coefficients for BOI estimation, air quality measurements, and health outcome data were also described. Air pollution-related BOI was discussed in terms of premature non-traumatic mortality and hospital admissions for respiratory and cardiovascular disease. The report reveals that Toronto has seen an increase in air pollution related to fossil-fuelled electrical generation, a decrease in transportation related primary pollutants, and a large increase in ozone. The dominant air problem in Toronto is the impact of transportation-related pollutants, particularly from diesel-powered heavy vehicles. In terms of policy implications, the literature suggests that focus should be placed on susceptible groups such as infants, children and the elderly. It was suggested that more studies should examine the role of the pollutant mix on susceptible groups instead of examining the effects of individual pollutants on the entire population. It was also suggested that air quality management strategies should be aimed at the sources of the most toxic components of the pollutant mix. 57 refs., 9 tabs., 2 figs., 3 appendices.

    Full Text Available Air pollution has been classified as Group 1 carcinogenic to humans, but the underlying tumorigenesis remains unclear. In Xuanwei City of Yunnan Province, the lung cancer incidence is among the highest in China attributed to severe air pollution generated by combustion of smoky coal, providing a unique opportunity to dissect lung carcinogenesis of air pollution. Here we analyzed the somatic mutations of 164 non-small cell lung cancers (NSCLCs from Xuanwei and control regions (CR where smoky coal was not used. Whole genome sequencing revealed a mean of 289 somatic exonic mutations per tumor and the frequent C:G → A:T nucleotide substitutions in Xuanwei NSCLCs. Exome sequencing of 2010 genes showed that Xuanwei and CR NSCLCs had a mean of 68 and 22 mutated genes per tumor, respectively (p < 0.0001. We found 167 genes (including TP53, RYR2, KRAS, CACNA1E which had significantly higher mutation frequencies in Xuanwei than CR patients, and mutations in most genes in Xuanwei NSCLCs differed from those in CR cases. The mutation rates of 70 genes (e.g., RYR2, MYH3, GPR144, CACNA1E were associated with patients' lifetime benzo(apyrene exposure. This study uncovers the mutation spectrum of air pollution-related lung cancers, and provides evidence for pollution exposure–genomic mutation relationship at a large scale.

    Full Text Available Background: Vehicular pollution is increasing in Indian cities, which may lead to increased number of patients with diseases related to air pollution. Present study was undertaken to assess the pattern of morbidity in two areas of Delhi, one highly polluted area (HPA and the other low polluted area (LPA. Materials and Methods: Subjects were interviewed regarding socioeconomic status and exposure history. Symptoms during the last month were recorded in a questionnaire and weight, height and peak expiratory flow rate (PEFR were measured. Air pollution data were obtained from the monitoring stations of Central Pollution Control Board (CPCB. Results: A total of 640 subjects participated in the study. Majority of the patients in both the areas were educated till primary but 24% in HPA and 13% in LPA were graduates. Current levels of all pollutants (except SO2 and NOx were above the safety levels prescribed by CPCB in both the areas, but the values were much higher in HPA. The values of PEFR amongst study population were more compromised in HPA. The difference in mean PEFR values among the populations in LPA and HPA were found to be statistically significant (P < 0.05. The mean number of symptoms experienced by subjects of HPA was more as compared to LPA (P < 0.05. Frequency of occurrence of symptoms varied with duration of stay in the study area. Children were affected more than the adults. Conclusion: Air pollution has a deleterious effect on various systems of the body.

    Full Text Available The chronic effects of air pollution in school children living near industrial sites were investigated. The respiratory symptoms of 806 school children aged 9-12 years were examined by the American Thoracic Society's Division of Lung Diseases (ATS-DLD-78-C questionnaire during February- August 2013. The selected elementary schools in this survey was based on the distance from Map Ta Phut Industrial Estate, area A within 1 km., area B 5 km. and area C 10 km. Logistic regression techniques were used to assess the association between prevalence of respiratory symptoms and independent variables. The average 24 hrs PM10 and VOCs concentrations from 2011-2014 in area A were significantly higher than in area C (p < 0.05. Relatively, the prevalence of respiratory symptoms in area A were high with odds ratios (OR = 3.41, (95% confidence intervals (CI = 1.70-6.85 and in area B with OR = 1.36, (95% CI = 0.54-3.45, in comparison to area C. The prevalent of non-specific respiratory diseases (NSRD and Persistent Cough and Phlegm (PCP in boy student were higher than girls students with OR=2.17, (95%CI=1.33-3.53, whereas those factors such as age, residential years, home size, parental smoking habits, use of air conditioners and domestic pets were not associated. Exposure to particulate matter and volatile organic compounds arising from Industrial sites was associated with worse respiratory impairments in children.

    This study evaluates the PM2.5 pollution-related health impacts on the national and provincial economy of China using a computable general equilibrium (CGE) model and the latest nonlinear exposure-response functions. Results show that the health and economic impacts may be substantial in provinces with a high PM2.5 concentration. In the WoPol scenario without PM2.5 pollution control policy, we estimate that China experiences a 2.00% GDP loss and 25.2 billion USD in health expenditure from PM2.5 pollution in 2030. In contrast, with control policy in the WPol scenario, a control investment of 101.8 billion USD (0.79% of GDP) and a gain of 1.17% of China's GDP from improving PM2.5 pollution are projected. At the provincial level, GDP loss in 2030 in the WoPol scenario is high in Tianjin (3.08%), Shanghai (2.98%), Henan (2.32%), Beijing (2.75%), and Hebei (2.60%) and the top five provinces with the highest additional health expenditure are Henan, Sichuan, Shandong, Hebei, and Jiangsu. Controlling PM2.5 pollution could bring positive benefits in two-thirds of provinces. Tianjin, Shanghai, Beijing, Henan, Jiangsu, and Hebei experience most benefits from PM2.5 pollution control as a result of a higher PM2.5 pollution and dense population distribution. Conversely, the control investment is higher than GDP gain in some underdeveloped provinces, such as Ningxia, Guizhou, Shanxi, Gansu, and Yunnan. PMID:27063584

  17. Air climate health

    International Nuclear Information System (INIS)

    'France Nature Environnement Ile de France' publishes, on occasion of the COP 21, a special paper about the air pollution in the Paris region, greenhouse gases and their influence on the environment. This document has been written in close cooperation with professionals and civil associations. Elected representatives from local and regional authorities also speak about their experiences. The first part emphasizes the urgency to accelerate preventive and corrective measures since the air pollution, after slightly decreasing in the 2000's, remains stable. Our work is a science based analysis of essential parameters and details the impact of local pollution and greenhouse gases on the climate. It is based on the GIEC 2013 and 2015 reports, as well as the work of National meteorology in association with the Climate agency of Paris. The threshold of not exceeding an average temperature of +2 deg. C in 2100 is almost reached. If consumption of fossil energies does not heavily decline in the next 10 years, the earth's thermal machine will enter, for several centuries, into an uncontrollable cycle which could endanger life on earth with average temperatures exceeding 4 to 6 deg. C above the current level. The second part reveals the impact of air pollution on the health of the Paris region's population, especially on women who are the most affected by respiratory diseases: obstructive pulmonary bronchitis and asthma. Four departments are particularly affected: Paris, Seine-et-Marne, Seine-Saint-Denis and Val-d'Oise. Even though we do not have the formal causal proof between gas concentration and disease, analysis of similar situations worldwide eliminate any doubts about the reality of the relationship. The third part proposes solutions which can be implemented by local government, companies, but also civil associations and citizens in order to quickly decrease greenhouse gas production. Solutions range from energy sobriety to change in travel

    Full Text Available OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers or office-workers were examined to determine carbon monoxide in exhaled breath and to measure the pH in nasal lavage fluid and exhaled breath condensate. Air pollution exposure was measured by particulate matter concentration, and data were obtained from fixed monitoring stations (8-h work intervals per day, during the 5 consecutive days prior to the study. RESULTS: Exhaled carbon monoxide was two-fold greater in traffic-controllers than in office-workers. The mean pH values were 8.12 in exhaled breath condensate and 7.99 in nasal lavage fluid in office-workers; these values were lower in traffic-controllers (7.80 and 7.30, respectively. Both groups presented similar cytokines concentrations in both substrates, however, IL-1β and IL-8 were elevated in nasal lavage fluid compared with exhaled breath condensate. The particulate matter concentration was greater at the workplace of traffic-controllers compared with that of office-workers. CONCLUSION: The pH values of nasal lavage fluid and exhaled breath condensate are important, robust, easy to measure and reproducible biomarkers that can be used to monitor occupational exposure to air pollution. Additionally, traffic-controllers are at an increased risk of airway and lung inflammation during their occupational activities compared with office-workers.

    Full Text Available This study assessed the public’s health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents’ demographics, perceived health risks from air pollution and sources of health-related knowledge on urban air pollution. Chi-square tests were used to examine if participants’ demographics were associated with participant’s general attitudes towards current air quality and the three perceived highest health risks due to urban air pollution. We found low rate of satisfaction of current urban air quality as well as poor knowledge of air pollution related indicator. Participants’ gender, age and travel experience were found to be associated with the satisfaction of current air quality. The knowledge of air pollution related indicator was significantly affected by respondents’ education, monthly income, health status, and sites of study. As many as 46.23% of the participants expressed their feelings of anxiety when exposed to polluted air, especially females, older adults and those with poor health conditions. Most participants believed that coughs/colds, eye problems and skin allergies were the three highest health risks due to urban air pollution based on public education through television/radio, internet and newspaper/magazine. Further public health education is needed to improve public awareness of air pollution and its effects.

    Rapid rural-urban migration has created overcrowded areas characterized by concentrated poverty and increases in indoor and outdoor air pollutants. These "hotspots" constitute an increased risk of violence and disease outbreaks. We hypothesize that the effects of poverty and associated air pollution-related stress on impaired cognitive skills are mediated by inflammatory cytokines. A research framework is proposed, encompassing (i) an epidemiological investigation of associations between poverty, high concentrations of air pollutants, violence and health, (ii) a longitudinal follow-up of working memory capacities and inflammatory markers, and (iii) intervention programs aiming to strengthen employability and decreased exposures to toxic air pollutants.

    There were 3.2 billion airline passengers in 2006, compared to only 30 million in 1950. Intercontinental health disparities create a risk of pandemics such as SARS and so-called bird flu. Precautions are now being implemented both in airports and in aircraft, in addition to measures intended to prevent the spread of malaria and arboviral diseases, such as vector eradication, elimination of stagnant water, malaria prophylaxis, vaccination, and use of repellents. These measures are dealt with in international health regulations, which have existed since 1851 and were last updated on 15 June 2007. Flying on an airliner also carries a risk of hypobaria (cabin pressure at 2000 m), which can aggravate respiratory problems. Other problems include relative hypoxia, gas expansion, air dryness, ozone, cosmic rays, airsickness, jet lag, the effects of alcohol and tobacco, and, more recently, deep vein thrombosis (DVT) and pulmonary embolism (PE), collectively known as "coach class syndrome". A new type of medicine has appeared, in the form of on-board medical assistance. The European Civil Aviation Committee has recommended first-aid training for cabin crews and onboard medical equipment such as first-aid kits and defibrillators. Airline statistics show that one in-flight medical incident occurs per 20 000 passengers, as well as one death per 5 million passengers and one medical reroute per 20 000 flights (40% of reroutes turn out to be unjustified). More than 80% of long-haul flights have a physician travelling on board. However, depending on his or her specialty, problems of competence and legal responsibility may arise. Ground-based medical centers can provide help via satellite telephone, but this implies the need for airline staff training. International cooperation is the only way to minimize the health risks associated with the growth in global air travel. PMID:20669640

  5. An Assessment of Air Pollution Exposure Information for Health Studies

    Directory of Open Access Journals (Sweden)

    Frederick W. Lipfert

    2015-11-01

    Full Text Available Most studies of air pollution health effects are based on outdoor ambient exposures, mainly because of the availability of population-based data and the need to support emission control programs. However, there is also a large body of literature on indoor air quality that is more relevant to personal exposures. This assessment attempts to merge these two aspects of pollution-related health effects, emphasizing fine particles. However, the basic concepts are applicable to any pollutant. The objectives are to examine sensitivities of epidemiological studies to the inclusion of personal exposure information and to assess the resulting data requirements. Indoor air pollution results from penetration of polluted outdoor air and from various indoor sources, among which environmental tobacco smoke (ETS is probably the most toxic and pervasive. Adequate data exist on infiltration of outdoor air but less so for indoor sources and effects, all of which have been based on surveys of small samples of individual buildings. Since epidemiology is based on populations, these data must be aggregated using probabilistic methods. Estimates of spatial variation and precision of ambient air quality are also needed. Hypothetical personal exposures in this paper are based on ranges in outdoor air quality, variable infiltration rates, and ranges of indoor source strength. These uncertainties are examined with respect to two types of mortality studies: time series analysis of daily deaths in a given location, and cross-sectional analysis of annual mortality rates among locations. Regressions of simulated mortality on personal exposures, as affected by all of these uncertainties, are used to examine effects on dose-response functions using quasi-Monte Carlo methods. The working hypothesis is that indoor sources are reasonably steady over time and thus applicable only to long-term cross-sectional studies. Uncertainties in exposure attenuate the simulated mortality

  6. 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

  7. Air Pollution and Climate Change Health Impact Assessment. The ACHIA Project

    International Nuclear Information System (INIS)

    Climate change may affect human health via interactions with air pollutants such as ozone and PM2.5. These air pollutants are linked to climate because they can be both affected by and have effects on climate. In coming decades, substantial, cost-effective improvements in public health may be achieved with well-planned strategies to mitigate climate impacts while also reducing health effects of ozone and PM2.5. Climate mitigation actions affect greenhouse pollutant emissions, including methane and black carbon, but also may affect other key air pollution precursors such as NOx, CO, and SOx. To better understand the potential of such strategies, studies are needed that assess possible future health impacts under alternative assumptions about future emissions and climate across multiple spatial scales. The overall objective of this project is to apply state of the art climate, air quality, and health modelling tools to assess future health impacts of ozone and PM2.5 under different IPCCs scenario of climate change, focusing specifically on pollution-related health co-benefits which could be achieved under alternative climate mitigation pathways in the period 2030-2050. This question will be explored at three spatial scales: global, regional (Europe), and urban (Paris). ACHIA is comprised of an integrated set of four work packages: WP1. Global Climate and Air Pollution Impacts of Alternative Emissions Pathways; WP2. Climate and Air Quality at Regional and Urban Scales: Results for Europe and Paris; WP3. Health Impact Assessment; WP4. Dissemination, Evaluation, Management. ACHIA is designed to create an interdisciplinary approach to the impacts of climate change on health through air quality changes, and to start longer-term collaborations between communities. We expect the project to advance state of art across all WPs, with important implications for research groups around the world. A particular innovation of the project is the multi-scale aspect, i.e., the analysis

    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.

  16. The Air Toxics Health Effects Database (ATHED)

    International Nuclear Information System (INIS)

    The Air Toxics Health Effects Database (ATHED) is currently used by the EPA's Office of Air Quality Planning and Standards (OAQPS) to support risk assessments for the Residual Risk Program. An assessment of the residual risk is required to be performed at a specified time (typically 8years) following the promulgation of a technology-based Maximum Achievable Control Technologies (MACT) standard. The goal of the Residual Risk Program is to assure that the risk that remains after MACT standards are implemented (i.e., the 'residual risk') is acceptable, and if not, to propose additional regulations to mitigate those risks. ATHED maintains all available reference values for each chemical as separate data records, and includes values for all exposure durations (acute, short-term, subchronic and chronic). These values are used as benchmarks to determine acceptable exposure levels to the hazardous air pollutants (HAPs) listed in Section 112 of the Clean Air Act. ATHED also provides useful background information on the uncertainty and/or modifying factors that were applied in the derivation of each reference value, as well as the point of departure and the critical study/studies. To facilitate comparisons across durations for a specific chemical, ATHED data can be graphically presented

    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.

    Nitrogen oxides (NOX) are important components of ambient and indoor air pollution and are emitted from a range of combustion sources, including on-road mobile sources, electric power generators, and non-road mobile sources. While anthropogenic sources dominate, NOX is also formed by lightning and wildland fires and is emitted by soil. Reduced nitrogen (e.g., ammonia, NH3) is also emitted by various sources, including fertilizer application and animal waste decomposition. NOX, ozone and PM2.5 pollution related to atmospheric emissions of nitrogen and other pollutants can cause premature death and a variety of serious health effects. Climate change is expected to impact how nitrogen-related pollutants affect human health. For example, changes in temperature and precipitation patterns are projected to both lengthen the ozone season and intensify high ozone episodes in some areas. Other climate-related changes may increase the atmospheric release of nitrogen compounds through impacts on wildfire regimes, soil emissions, and biogenic emissions from terrestrial ecosystems. This session will examine the potential human health implications of climate change and nitrogen cycle interactions related to ambient air pollution.

  19. Urban Air Environmental Health Indicators for Kuala Lumpur City

    International Nuclear Information System (INIS)

    Air environmental health indicators were defined operationally as a combination of air quality and air-related health indicators. Clean air is a basic precondition of human health. Air pollutants had been identified with potential negative impact on health especially on respiratory and cardiovascular diseases. Thus, studies are necessary to identify and understand the state of environmental health. This study was aimed to examine and analyses the air environmental health condition in city of Kuala Lumpur by using a set of indicators. House to house questionnaire survey was carried out to collect air-related health data, and air quality sampling was carried out to identify ambient air quality level of the city. In general, city of Kuala Lumpur was found to have a moderate level of air quality. Air-related illnesses indicated by acute respiratory infection and asthma were found to be higher in more developed or higher density zones, as compared to other zones. Besides, air-related illnesses were significantly correlated to respondents exposure to air pollution. The findings imply that human health can be improved by managing the urban development and its environmental quality properly. (author)

    1995-12-31

    Air pollution epidemiology is the study of the occurrence and distribution of health outcomes in association with community air pollution exposure. 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.

    Leading medical and public health organizations are deeply concerned about the proposed revisions to the National Ambient Air Quality Standard (NAAQS) that the US Environmental Protection Agency (EPA) announced in December 2005. Led by the American Lung Association (ALA), these groups are fighting to force EPA to finalize stricter standards for fine and coarse particles when the final decision is announced in September 2006. The ALA disagrees strongly with the proposal to exempt coarse particles from agriculture and mining sources, and to exclude communities with populations fewer than 100,000 from protection and monitoring requirements. ALA urges EPA to set the following health-based NAAQS for PM: Annual average PM2.5 standard of 12 {mu}mg/m{sup 3}; 24 hour average PM2.5 standard of 25 {mu}mg.m{sup 3} (99th percentile); 24-hour average PM10-2.5 standard of 25-30 {mu}g/m{sup 3} (99th percentile), applied equally to all areas of the country and to all types of particles. 72 refs., 2 figs., 1 tab.

    Environmental departments consider geographical maps with information on air quality as the final product of a complicated process of measuring, modelling and presentation. Municipal health departments consider such maps a useful starting point to solve the problem whether air pollution causes health risks for citizens. The answer to this question cannot be reduced to checking if threshold limit values are exceeded. Based on the results of measurements and modelling of concentrations of nitrogen dioxide in air, the health significance of air pollution caused by nitrogen dioxide is illuminated. A proposal is presented to map health risks of air pollution by using the results of measurements and modelling of air pollution. 7 refs

    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.

    2012-12-01

    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

    The "Provence Alpes Côte d'Azur" (PACA) region, in the South East of France, is one of Europe's regions most influenced by the atmospheric pollution. During the last 15 years, the industrial emissions decrease caused an evolution of the atmospheric pollution nature. Nowadays, atmospheric pollution is more and more influenced by the road traffic, the dominating pollution source in urban zones for the PACA region. Combined with this intense road traffic, the strong hot season of the Mediterranean climate contributes to the region bad air quality; it is known to be one of the worse in Europe. The recognized air pollution effects over public health include increased risk of hospital admissions and mortality by respiratory or cardiovascular diseases. The combination of these serious pollution related health hazards with senior and children vulnerabilities leads to serious sanitary concerns. Over the 1990-2005 period, we obtained, using the non-parametric Mann-Kendall test from annual mortality dataset (CépiDC), decreasing trends for Asthma (-5.00% year -1), Cardiovascular (-0.73% year -1), Ischemic (-0.69% year -1) and cerebrovascular diseases (-3.10% year -1). However, for "Other heart diseases" (+0.10% year -1) and "Respiratory" (+0.10% year -1) an increase was observed. The development of an adequate tool to understand impacts of pollution levels is of utmost importance. Different pollutants have different health endpoints, information may be lost through the use of a single index consequently, in this study we present the modified formula of air quality index, based on Cairncross's concept the Aggregate Risk Index (ARI). ARI is based on the relative risk of the well-established increased daily mortality, or morbidity, enabling an assessment of additive effects of short-term exposure to the main air pollutants: PM 2.5, PM 10, SO 2, O 3 and NO 2 in order to account for the reality of the multiple exposures impacts of chemical agents.

    This study provided estimates the health benefits and costs associated with specified changes in ambient air concentrations of particulate matter (PM) and ozone in the Lower Fraser Valley (LFV). Estimates were developed on a regional level. The study focused on PM and ozone, as current air quality monitoring data and scientific findings have indicated that these are the air contaminants of greatest concern in the region. Known air quality health outcome relationships were applied in a spreadsheet model to predict changes in health outcomes associated with 6 ambient air quality scenarios for 3 sub-regions within the LFV airshed. Concentration response functions based on epidemiological studies were used to estimate the number of health events associated with changes in air quality. For each scenario, the model calculated the expected number of the following health outcomes: mortality; chronic bronchitis; respiratory hospital admissions; cardiac hospital admissions; emergency room visits; child acute bronchitis; restricted activity days; asthma symptom days; minor restricted activity days and acute respiratory symptom days. The model also produced the dollar value of the health outcomes. A dollar metric was used so that the health outcomes could be aggregated and compared with other air quality management actions such the costs of improving ambient air quality. Results indicated that improving ambient air quality in the LFV will produce valued and socially desirable benefits, including reduced mortality and morbidity. The measures contemplated by decision-makers to maintain and improve air quality in the LFV will trigger benefits that are likely to be significant. 101 refs., 7 tabs., 7 figs.

    The new Air Quality Health Index (AQHI) is a tool aiming to present the health risks related to air pollution in Canada. This index can be used by individuals to help them reduce their health risk resulting from poor air quality. An assessment of the short term health risk induced by poor air quality is provided to Canadians through the AQHI. The AQHI is based on three factors: ambient concentrations of nitrogen dioxide, fine particulate matter and ozone, the local air quality information being presented on an hourly and daily basis and being calculated each hour for several locations across Canada. Pulmonary disorders and impacts on cardiac function are the more significant short term health risks. Longer term exposure to poor air quality is associated with increased rates of allergies and asthma, low birth weight, atherosclerosis, poorer lung development in children, lung cancer and ear infections. Information on the AQHI and on the variation across British Columbia of the health risk associated with this index are presented in this document. 19 refs., 5 tabs., 5 figs.

    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

    It is often argued that liquid biofuels are cleaner than fossil fuels, and therefore better for human health, however, the evidence on this issue is still unclear. Brazil’s high uptake of ethanol and role as a major producer makes it the most appropriate case study to assess the merits of different biofuel policies. Accordingly, we modeled the impact on air quality and health of two future fuel scenarios in São Paulo State: a business-as-usual scenario where ethanol production and use proceeds according to government predictions and a counterfactual scenario where ethanol is frozen at 2010 levels and future transport fuel demand is met with gasoline. The population-weighted exposure to fine particulate matter (PM2.5) and ozone was 3.0 μg/m3 and 0.3 ppb lower, respectively, in 2020 in the scenario emphasizing gasoline compared with the business-as-usual (ethanol) scenario. The lower exposure to both pollutants in the gasoline scenario would result in the population living 1100 additional life-years in the first year, and if sustained, would increase to 40,000 life-years in year 20 and continue to rise. Without additional measures to limit emissions, increasing the use of ethanol in Brazil could lead to higher air pollution-related population health burdens when compared to policy that prioritizes gasoline.

  5. 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

    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 New Mexico Air Quality Mapper (NMAQM) is a Web-based, open source GIS prototype application that Earth Data Analysis Center is developing under a NASA Cooperative Agreement. NMAQM enhances and extends existing data and imagery delivery systems with an existing Public Health system called the Rapid Syndrome Validation Project (RSVP). RSVP is a decision support system operating in several medical and public health arenas. It is evolving to ingest remote sensing data as input to provide early warning of human health threats, especially those related to anthropogenic atmospheric pollutants and airborne pathogens. The NMAQM project applies measurements of these atmospheric pollutants, derived from both remotely sensed data as well as from in-situ air quality networks, to both forecasting and retrospective analyses that influence human respiratory health. NMAQM provides a user-friendly interface for visualizing and interpreting environmentally-linked epidemiological phenomena. The results, and the systems made to provide the information, will be applicable not only to decision-makers in the public health realm, but also to air quality organizations, demographers, community planners, and other professionals in information technology, and social and engineering sciences. As an accessible and interactive mapping and analysis application, it allows environment and health personnel to study historic data for hypothesis generation and trend analysis, and then, potentially, to predict air quality conditions from daily data acquisitions. Additional spin off benefits to such users include the identification of gaps in the distribution of in-situ monitoring stations, the dissemination of air quality data to the public, and the discrimination of local vs. more regional sources of air pollutants that may bear on decisions relating to public health and public policy.

  8. Inside environment, air quality and health

    International Nuclear Information System (INIS)

    It is now obvious that there is a risk of lung cancer because of the radon exposure in houses. The domestic exposure is the second cause of the lung cancer after tobacco. It is possible to reduce the concentration in radon in houses. The domestic exposure to radon is a problem of public health that we have to manage. The question is to know to what point from a technical, economical and public health point of view. Studies about cost-efficiency should be made to better direct the political actions on radon. Two points are important to fight against bad effects of radon, the reduction of radon levels in houses and the fight against addiction to smoking. (N.C.)

    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.

    Situated in the central region of South Africa, the Vaal Triangle is an area which plays a vital role in driving the economic dynamo of South Africa. Also, because of the concentration of heavy industry, it is an area which provides a challenge in effective air pollution control. The Vaal Triangle lies within the Vaal River Basin, at an altitude of 1 500 m above sea level. Meteorological conditions in the area are highly conducive to the formation of surface temperature inversions, resulting in a poor dispersion potential. Because of multiple sources of air pollution in the area, poor dispersion conditions increase the risk pollution build-up and subsequent adverse impacts. The situation is further exacerbated by the continued combustion of coal in households, even after the electrification of residences. This is particularly chronic in the developing communities and during winter. Vaal Triangle Air Pollution Health Study (VAPS) was initiated in 1990 by the Department of Health, the Medical Research Council and major industries in the area to determine effects of air pollution on the health of the community. The final results of that study summarised in this article, and options to ameliorate problems are addressed. (author)

  19. Air pollution health effects of electric power generation

    International Nuclear Information System (INIS)

    stitutt for Atomenergi (IFA) and Norsk Institutt for Luftforskning (NILU) have undertaken a joint project with the ultimate purpose of comparing the relative air pollution health effects of gas-fired, oil-fired and uranium-fueled electric power generating plants. Phase I of the project includes a literature review on pollutant emissions and their health effects. The methods which have previouously been used to compare the relative health effects are also reviewed. The radioactive effluents from nuclear power plants are tabulated and the health effects discussed on the basis of data from Hiroshima and Nagasaki, medical irradiation therapy and studies of USAEC and UKAEA employees. It is pointed out that there is no indication that chronic low-level radiation has somatic effects, and the Japanese data gives no conclusive indication of genetic effects. Background irradiation in Kerala and Guarapari and in USA is also cited. Following a brief presentation of the principal air pollutants from fossil fuels a number of studies of 'smog' incidents in the UK and USA are discussed, and a prediction equation based on multiple regression analysis is presented. Finally the methods of comparing the health effects from nuclear and fossil-fuel plants are discussed. In an appendix Lave and Freeburg's study 'Health effects of electricity generation from coal, oil and nuclear fuel' is evaluated. (JIW)

  20. Categories of adverse health effects from indoor air pollution

    International Nuclear Information System (INIS)

    There is a lack of precision in the definition of health, which leads to confusion in the assessment of adverse effects arising from indoor air pollution. Adverse health effects range from annoyance to life-threatening conditions. Survey responses suggest that males and females differ in their perception of a healthy person, but both sexes envisage a male in terms of positive fitness, strength, energy and the possession of an athletic body, rather than how long one was likely to live. Psychological fitness was relatively unimportant in describing the health of others, but was rates as very important with respect to one's own health. Mortality statistics tend to obscure the proportion of the population who suffer chronic illness that is not life threatening. Although health is largely determined by genetic constitution, lifestyle and environmental factors, the morale of an individual is also important. A new classification of the adverse effects on health of indoor air pollution is proposed: this includes 'comfort' responses, such as sick building syndrome (category 1); acute chemical effects, the nature of which depends upon the specific intoxicant (category 2B), and perceived chronic grave risk, including cancer causation (category 3). The magnitude of risk in this latter category is imprecise, because its measurement involves the technique of quantitative risk assessment. (author) 1 fig., 2 tabs., 158 refs

    Since 2000, the government in Shanxi province has mounted several initiatives and mandated factory shutdowns with the goal of reducing coal burning emissions and the environmental impacts of industrialization. We estimated the health benefits associated with air quality improvement from 2001 to 2010 in Taiyuan, Shanxi Province, using disability-adjusted life years (DALYs) and monetized the health benefits using value of statistical life (VOSL). Data were collected on annual average concentrations of particulate matter less than 10 μm in aerodynamic diameter (PM10) and relevant health outcomes in Taiyuan from 2001 to 2010. Selected exposure-response functions were used to calculate the cases of death or disease attributable to PM10 annually over a 10-year period. These were summed to calculate the DALYs lost and their monetary value associated with PM10 each year between 2001 and 2010. Air quality improvement from 2001 to 2010 was estimated to have prevented 2810 premature deaths, 951 new cases of chronic bronchitis, 141,457 cases of outpatient visits, 969 cases of emergency-room visits and 31,810 cases of hospital admissions. The DALYs (VOSL) decreased by 56.92% (52.68%) from 52,937 (7274 million Yuan) in 2001 to 22,807 (3442 million Yuan) in 2010. Premature deaths accounted for almost 95% of the total DALYs. Our analysis demonstrates that air pollution abatement during the last decade in Taiyuan has generated substantial health benefits. PMID:25168129

  2. The impact of weather changes on air quality and health in the United States in 1994–2012

    International Nuclear Information System (INIS)

    Air quality is heavily influenced by weather conditions. In this study, we assessed the impact of long-term weather changes on air quality and health in the US during 1994–2012. We quantified past weather-related increases, or ‘weather penalty’, in ozone (O3) and fine particulate matter (PM2.5), and thereafter estimated the associated excess deaths. Using statistical regression methods, we derived the weather penalty as the additional increases in air pollution relative to trends assuming constant weather conditions (i.e., weather-adjusted trends). During our study period, temperature increased and wind speed decreased in most US regions. Nationally, weather-related 8 h max O3 increases were 0.18 ppb per year (95% CI: 0.06, 0.31) in the warm season (May–October) and 0.07 ppb per year (95% CI: 0.02, 0.13) in the cold season (November–April). The weather penalties on O3 were relatively larger than PM2.5 weather penalties, which were 0.056 μgm−3 per year (95% CI: 0.016, 0.096) in warm months and 0.027 μgm−3 per year (95% CI: 0.010, 0.043) in cold months. Weather penalties on O3 and PM2.5 were associated with 290 (95% CI: 80, 510) and 770 (95% CI: 190, 1350) excess annual deaths, respectively. Over a 19-year period, this amounts to 20 300 excess deaths (5600 from O3, 14 700 from PM2.5) attributable to the weather penalty on air quality. (letter)

    1997-06-16

    This report examines the potential health effects of non radiological emissions to the air resulting from operations at the Savannah River Site (SRS). The scope of this study was limited to the 55 air contaminants for which the US Environmental Protection Agency (EPA) has quantified risk by determining unit risk factors (excess cancer risks) and/or reference concentrations (deleterious non cancer risks). Potential health impacts have been assessed in relation to the maximally exposed individual. This is a hypothetical person who resides for a lifetime at the SRS boundary. The most recent (1994) quality assured SRS emissions data available were used. Estimated maximum site boundary concentrations of the air contaminants were calculated using air dispersion modeling and 24-hour and annual averaging times. For the emissions studied, the excess cancer risk was found to be less than the generally accepted risk level of 1 in 100,000 and, in most cases, was less than 1 in 1,000,000. Deleterious non cancer effects were also found to be very unlikely.

    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)

  9. Household energy, air pollution and health in Maputo

    Energy Technology Data Exchange (ETDEWEB)

    Ellegaard, A.

    1997-05-01

    A survey was carried out in 1188 low-income households in Maputo, Mocambique, in order to assess the degree of exposure to air pollution and health effects associated with this exposure. The hypothesis was that pollution from biomass fuels, especially wood, impairs the health of the women using them, and that it would be possible to discern this effect in a general population. Average exposure levels during cooking time were found to be high, with a level of respirable particulates at 1200, 540 and 380 {mu}g/m{sup 3} for wood, charcoal and electricity users respectively. Similarly carbon monoxide levels were 42, 37 and 5 ppm for the same groups. Wood users were found to have significantly more symptoms of respiratory problems than users of other fuels, but also significantly more symptoms that could not be immediately associated with household fuel pollution. Thus, wood users had lower literacy, poorer housing, and more primitive access to water and sanitation. There was little difference in health aspects between charcoal users and users of modern fuels, though exposure to air pollution was higher among charcoal users. In statistical analysis it was found that cough were significantly associated with the use of wood as a principal fuel, but not with the use of charcoal. Other variables that influenced the health outcome were the age when a woman started helping her mother to cook, daily cooking time and kitchen ventilation. Most of the variables associated to ill health were correlated to wood use. In contrast, charcoal use was associated with a better health status in many respects. From the point of pollution exposure and health, wood use should be limited, while charcoal appears to be a feasible intermediate substitute for wood in the short term in Maputo. 48 refs, 31 figs, 33 tabs

  10. Household energy, air pollution and health in Maputo

    International Nuclear Information System (INIS)

    A survey was carried out in 1188 low-income households in Maputo, Mocambique, in order to assess the degree of exposure to air pollution and health effects associated with this exposure. The hypothesis was that pollution from biomass fuels, especially wood, impairs the health of the women using them, and that it would be possible to discern this effect in a general population. Average exposure levels during cooking time were found to be high, with a level of respirable particulates at 1200, 540 and 380 μg/m3 for wood, charcoal and electricity users respectively. Similarly carbon monoxide levels were 42, 37 and 5 ppm for the same groups. Wood users were found to have significantly more symptoms of respiratory problems than users of other fuels, but also significantly more symptoms that could not be immediately associated with household fuel pollution. Thus, wood users had lower literacy, poorer housing, and more primitive access to water and sanitation. There was little difference in health aspects between charcoal users and users of modern fuels, though exposure to air pollution was higher among charcoal users. In statistical analysis it was found that cough were significantly associated with the use of wood as a principal fuel, but not with the use of charcoal. Other variables that influenced the health outcome were the age when a woman started helping her mother to cook, daily cooking time and kitchen ventilation. Most of the variables associated to ill health were correlated to wood use. In contrast, charcoal use was associated with a better health status in many respects.

    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

    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.

  15. Ambient air pollution exposure and the incidence of related health effects among racial/ethnic minorities

    Nieves, L.A.; Wernette, D.R.

    1997-02-01

    Differences among racial and ethnic groups in morbidity and mortality rates for diseases, including diseases with environmental causes, have been extensively documented. However, documenting the linkages between environmental contaminants, individual exposures, and disease incidence has been hindered by difficulties in measuring exposure for the population in general and for minority populations in particular. After briefly discussing research findings on associations of common air pollutants with disease incidence, the authors summarize recent studies of radial/ethnic subgroup differences in incidence of these diseases in the US. They then present evidence of both historic and current patterns of disproportionate minority group exposure to air pollution as measured by residence in areas where ambient air quality standards are violated. The current indications of disproportionate potential exposures of minority and low-income populations to air pollutants represent the continuation of a historical trend. The evidence of linkage between disproportionate exposure to air pollution of racial/ethnic minorities and low-income groups and their higher rates of some air pollution-related diseases is largely circumstantial. Differences in disease incidence and mortality rates among racial/ethnic groups are discussed for respiratory diseases, cancers, and lead poisoning. Pollutants of concern include CO, Pb, SO{sub 2}, O{sub 3}, and particulates.

  16. Valdez air health study - Exposure monitoring and risk assessment

    International Nuclear Information System (INIS)

    In Valdez, Alaska there is concern about exposure of the public to benzene and other light hydrocarbons emitted during the loading of tankers from the Trans-Alaska Pipeline. As part of an overall risk assessment, the Valdez Air Health Study, a personal, indoor and outdoor air sampling program patterned after EPA's TEMA Study was designed and carried out. A unique feature of the study is that, during sampling periods, SF6 tracer was released at the terminal site to represent terminal hydrocarbon emissions to provide a basis for directly quantitating any contribution of terminal emissions to personal exposure. Sixty citizens at Valdez were selected to wear vests containing sampling equipment for 24-hour periods summer and winter. At the homes of 30 of the participants simultaneous indoor and outdoor samples for hydrocarbons and tracer were collected during the period that each participant collected personal air samples. The paper reviews the design of the program, details of the procedures used, results of the August, 1990 program and preliminary results from the February-March, 1991 program

    2016-01-01

    The objective of this study was to briefly review air pollution and its effects on athletes' health and performance and to examine air quality (AQ) at specific Olympic Summer Games between 1964 and 2008. It will focus on any attempts made by the cities hosting these Olympics to improve AQ for the Games and if undertaken, how successful these were. The author had a medical role at five of the seven Olympic Games that will be examined and hence has personal experiences. Information was obtained from the readily accessible official reports of the Olympic Games, relevant published papers and books and the internet. For each of these seven Olympic Games, monitoring AQ was far below current acceptable standards and for the majority, minimal or no data on major pollutants was available. From what can be ascertained, at these Games, AQ varied but was less than optimal in most if not all. Nevertheless, there were few reported or known unfavorable effects on the health of Olympic athletes. To date, there have been few reported consequences of sub-optimal AQ at Olympic Games. The focus on AQ at Olympic Games has gradually increased over the past five decades and is expected to continue into the future. PMID:25786594

    The hallmarks of sickle cell disease are anemia and vasculopathy. The aim of this study was to assess the association between air pollution and children's emergency room visits of sickle cell patients. We adopted a case-crossover design. Daily counts of children's and adolescents' sickle cell disease emergency room visits from the pediatric emergency unit in São Paulo, Brazil, were evaluated from September 1999 to December 2004, matching by temperature, humidity and controlling for day of the week. Interquartile range increases of the four-day moving averages of PM10, NO2, SO2, CO, and O3 were associated with increases of 18.9% (95%CI: 11.2-26.5), 19% (95%CI: 8.3-29.6), 14.4% (95%CI: 6.5-22.4), 16,5% (95%CI: 8.9-24.0), and 9.8% (95%CI: 1.1-18.6) in total sickle cell emergency room visits, respectively. When the analyses were stratified by pain, PM10 was found to be 40.3% higher than in sickle cell patients without pain symptoms. Exposure to air pollution can affect the cardiovascular health of children and may promote a significant health burden in a sensitive group. PMID:25760161

  20. Air pollution and health risks due to vehicle traffic.

    2013-04-15

    Traffic congestion increases vehicle emissions and degrades ambient air quality, and recent studies have shown excess morbidity and mortality for drivers, commuters and individuals living near major roadways. Presently, our understanding of the air pollution impacts from congestion on roads is very limited. This study demonstrates an approach to characterize risks of traffic for on- and near-road populations. Simulation modeling was used to estimate on- and near-road NO2 concentrations and health risks for freeway and arterial scenarios attributable to traffic for different traffic volumes during rush hour periods. The modeling used emission factors from two different models (Comprehensive Modal Emissions Model and Motor Vehicle Emissions Factor Model version 6.2), an empirical traffic speed-volume relationship, the California Line Source Dispersion Model, an empirical NO2-NOx relationship, estimated travel time changes during congestion, and concentration-response relationships from the literature, which give emergency doctor visits, hospital admissions and mortality attributed to NO2 exposure. An incremental analysis, which expresses the change in health risks for small increases in traffic volume, showed non-linear effects. For a freeway, "U" shaped trends of incremental risks were predicted for on-road populations, and incremental risks are flat at low traffic volumes for near-road populations. For an arterial road, incremental risks increased sharply for both on- and near-road populations as traffic increased. These patterns result from changes in emission factors, the NO2-NOx relationship, the travel delay for the on-road population, and the extended duration of rush hour for the near-road population. This study suggests that health risks from congestion are potentially significant, and that additional traffic can significantly increase risks, depending on the type of road and other factors. Further, evaluations of risk associated with congestion must

    Population growth, rapid urbanization and economic development are contributing to increased energy consumption in China. One of the unintended consequences is poor air quality due to a lack of environmental controls. The coal dependent energy structure in China only worsens the situation. Quantification of the environmental costs resulting from air pollution is needed in order to provide a mechanism for making strategic energy policy that accounts for the life-cycle cost of energy use. However, few such studies have been conducted for China that examine the entire energy system. Here we examine the extent to which public health has been compromised due to elevated air pollution and how China could incorporate environmental costs into future energy and environmental policies. Taking the Shandong region in eastern China as a case study, we develop a high-resolution regional inventory for anthropogenic emissions of NOx, CO, PM2.5, PM10, VOCs, NH3 and SO2. SMOKE (Sparse Matrix Operator Kernel Emissions Modeling System) is used to process spatial and temporal distributions and chemical speciation of the regional emissions, MM5 (the Fifth-Generation NCAR/Penn State Meso-scale Model, Version 3) is used to generate meteorology and Models3/CMAQ (Community Multi-scale Air Quality Modeling System) is used to simulate ambient concentrations of particulates and other gaseous species in this region. We then estimate the mortality and morbidity in this region resulting from exposure to these air pollutants. We also estimate the monetary values associated with the resulting mortality and morbidity and quantify the contributions from various economic sectors (i.e. power generation, transportation, industry, residential and others). Finally, we examine the potential health benefits that adoption of best available or advanced energy (coal-based, in particular) and environmental technologies in different sectors could bring about. The results of these analyses are intended to provide

    Drug abuse assessment methods based on measuring illicit substances in waste waters are consolidated. The approach of ambient air monitoring looks questionable, nonetheless it can be explored if the variables determining the drug burdens are accounted for, or suitable co-contaminants are adopted to normalize concentrations to environmental and human contours. The general approach linking the airborne drug concentrations to consumption is presented and the case of cocaine is discussed according to measurements conducted in Italy. The cocaine/nicotine concentration ratio, identified as the most suitable tool, fitted well with anti-drug Police operations and people noticed for drug-related crimes, and with the abuse prevalence estimated in the cities investigated. According to that, the conversion factors of drug concentrations into prevalence estimates seem assessable, provided sufficient databases over space and time are collected. Further investigations are necessary to understand if airborne drugs cause adverse sanitary effects. -- Highlights: •The drug contents in the air were discussed to draw information about abuse prevalence. •The time and site drug modulations were compared to those of the airborne toxicants. •Nicotine looks suitable to normalize the cocaine concentrations to human and environmental contours. •The health impact of illicit and licit drugs onto non-abusers is still insufficiently understood. -- The airborne cocaine/nicotine concentration ratio looks a promising tool to estimate the cocaine abuse prevalence

    Our objective is to establish the link between energy consumption and technologies, air pollution concentrations, and resulting impacts on public health in eastern China. We use Zaozhuang, a city in eastern China heavily dependent on coal, as a case study to quantify the impacts that air pollution in eastern China had on public health in 2000 and the benefits in improved air quality and health that could be obtained by 2020, relative to business-as-usual (BAU), through the implementation of best available emission control technology (BACT) and advanced coal gasification technologies (ACGT). We use an integrated assessment approach, utilizing state-of-the-science air quality and meteorological models, engineering, epidemiology, and economics, to achieve this objective. We find that total health damages due to year 2000 anthropogenic emissions from Zaozhuang, using the 'willingness-to-pay' metric, was equivalent to 10% of Zaozhuang's GDP. If all health damages resulting from coal use were internalized in the market price of coal, the year 2000 price would have more than tripled. With no new air pollution controls implemented between 2000 and 2020 but with projected increases in energy use, we estimate health damages from air pollution exposure to be equivalent to 16% of Zaozhuang's projected 2020 GDP. BACT and ACGT (with only 24% penetration in Zaozhuang and providing 2% of energy needs in three surrounding municipalities) could reduce the potential health damage of air pollution in 2020 to 13% and 8% of projected GDP, respectively. Benefits to public health, of substantial monetary value, can be achieved through the use of BACT; health benefits from the use of ACGT could be even larger.

    In many areas of the world, concentrations of ambient air pollutants exceed levels associated with increased risk of acute and chronic health problems. While effective policies to reduce emissions at their sources are clearly preferable, some evidence supports the effectiveness of individual actions to reduce exposure and health risks. Personal exposure to ambient air pollution can be reduced on high air pollution days by staying indoors, reducing outdoor air infiltration to indoors, cleaning indoor air with air filters, and limiting physical exertion, especially outdoors and near air pollution sources. Limited evidence suggests that the use of respirators may be effective in some circumstances. Awareness of air pollution levels is facilitated by a growing number of public air quality alert systems. Avoiding exposure to air pollutants is especially important for susceptible individuals with chronic cardiovascular or pulmonary disease, children, and the elderly. Research on mechanisms underlying the adverse health effects of air pollution have suggested potential pharmaceutical or chemopreventive interventions, such as antioxidant or antithrombotic agents, but in the absence of data on health outcomes, no sound recommendations can be made for primary prevention. Health care providers and their patients should carefully consider individual circumstances related to outdoor and indoor air pollutant exposure levels and susceptibility to those air pollutants when deciding on a course of action to reduce personal exposure and health risks from ambient air pollutants. Careful consideration is especially warranted when interventions may have unintended negative consequences, such as when efforts to avoid exposure to air pollutants lead to reduced physical activity or when there is evidence that dietary supplements, such as antioxidants, have potential adverse health effects. These potential complications of partially effective personal interventions to reduce exposure or

    China is at its most critical stage of outdoor air quality management. In order to prevent further deterioration of air quality and to protect human health, the Chinese government has made a series of attempts to reduce ambient air pollution. Unlike previous literature reviews on the widespread hazards of air pollution on health, this review article firstly summarized the existing evidence of human health benefits from intermittently improved outdoor air quality and intervention in China. Contents of this paper provide concrete and direct clue that improvement in outdoor air quality generates various health benefits in China, and confirm from a new perspective that it is worthwhile for China to shift its development strategy from economic growth to environmental economic sustainability. Greater emphasis on sustainable environment design, consistently strict regulatory enforcement, and specific monitoring actions should be regarded in China to decrease the health risks and to avoid long-term environmental threats.

    2008-01-01

    The health burden of environmental exposures, including ambient air pollution and climate-change-related health impacts, is not equally distributed between or within regions and countries. These inequalities are currently receiving increased attention in environmental research as well as enhanced appreciation in environmental policy, where calls for environmental equity are more frequently heard. The World Health Organization (WHO) 2006 Global Update of the Air Quality Guidelines attempted to address the global-scale inequalities in exposures to air pollution and the burden of diseases due to air pollution. The guidelines stop short, however, of addressing explicitly the inequalities in exposure and adverse health effects within countries and urban areas due to differential distribution of sources of air pollution such as motor vehicles and local industry, and differences in susceptibility to the adverse health effects attributed to air pollution. These inequalities, may, however, be addressed in local air quality and land use management decisions. Locally, community-based participatory research can play an important role in documenting potential inequities and fostering corrective action. Research on environmental inequities will also benefit from current efforts to (1) better understand social determinants of health and (2) apply research evidence to reduce health disparities. Similarly, future research and policy action will benefit from stronger linkages between equity concerns related to health consequences of both air pollution exposure and climate change, since combustion products are important contributors to both of these environmental problems.

    Full Text Available Air pollution is the environmental factor with the greatest impact on health and is responsible for the largest burden of environmental related diseases. Pollutants in the air causing health risk to everyone particularly the children. Over a decade, a considerable number of research studies have reported adverse health effects associated with air pollution. The harm caused by air pollutants has been already recognized by medical practitioners, and researcher. There are basically two types of air pollutants, outdoor and indoor. Whatever may be the sources, the pollutant in the air can damage lungs at cellular levels, can reduce lung functions, increases the chances of respiratory illness and asthma ,increases sickness rates and may even increases the death rate. Children are the most vulnerable groups among us who are the worst sufferer of air pollution.

    Trees remove air pollutants through dry deposition processes depending upon forest structure, meteorology, and air quality that vary across space and time. Employing nationally available forest, weather, air pollution and human population data for 2010, computer simulations were performed for deciduous and evergreen trees with varying leaf area index for rural and urban areas in every county in the conterminous United States. The results populated a national database of annual air pollutant removal, concentration changes, and reductions in adverse health incidences and costs for NO2, O3, PM2.5 and SO2. The developed database enabled a first order approximation of air quality and associated human health benefits provided by trees with any forest configurations anywhere in the conterminous United States over time. Comprehensive national database of tree effects on air quality and human health in the United States was developed. PMID:27176764

  2. Health and air quality 2002 phase 1 : methods for estimating and applying relationships between air pollution and health effects : final report

    International Nuclear Information System (INIS)

    The British Columbia Lung Association recruited members of an expert panel to examine the relationships between exposure to air pollution and effects on human health, in particular human respiratory and cardio-vascular health. This report is intended for regulatory managers, planners, project proponents, researchers and physicians. It reports on the available literature on the subject and offers recommendations on how it can be interpreted in terms of application to problems in British Columbia and the Pacific Northwest. The common air contaminants that are associated with direct human health effects include nitrogen oxides, sulphur oxides, carbon monoxide, ozone, fine particles and inhalable particles (PM). The review did not include toxic or hazardous air pollutants that are considered to be cancer-causing agents, however, the association between air pollution and elevated rates of cancer in urban populations was considered. The panel considered: pollutant mix and exposure patterns; different types of studies such as epidemiology; sources of uncertainty; and, several criteria for judging the power of the relationships. It was concluded that some air pollutants, particularly PM 2.5 and its wood smoke component and ozone are at levels that may cause adverse health effects. It was noted that affected communities should be aware that risk increases with level of exposure and risk of health effects is very low at the lowest ambient concentrations in British Columbia and increases proportionally to ambient concentrations of PM and ozone. refs., tabs., figs

    Despite past improvements in air quality, very large parts of the population in urban areas breathe air that does not meet European standards let alone the health-based World Health Organisation Air Quality Guidelines. Over the last 10 years, there has been a substantial increase in findings that particulate matter (PM) air pollution is not only exerting a greater impact on established health endpoints, but is also associated with a broader number of disease outcomes. Data strongly suggest that effects have no threshold within the studied range of ambient concentrations, can occur at levels close to PM2.5 background concentrations and that they follow a mostly linear concentration-response function. Having firmly established this significant public health problem, there has been an enormous effort to identify what it is in ambient PM that affects health and to understand the underlying biological basis of toxicity by identifying mechanistic pathways-information that in turn will inform policy makers how best to legislate for cleaner air. Another intervention in moving towards a healthier environment depends upon the achieving the right public attitude and behaviour by the use of optimal air pollution monitoring, forecasting and reporting that exploits increasingly sophisticated information systems. Improving air quality is a considerable but not an intractable challenge. Translating the correct scientific evidence into bold, realistic and effective policies undisputedly has the potential to reduce air pollution so that it no longer poses a damaging and costly toll on public health.

    Good indoor air quality in schools is important to provide a safe, healthy, productive, and comfortable environment for students, teachers, and other school staff. However, existing studies demonstrated that various air pollutants are found in classrooms, sometimes at elevated concentrations. Data also indicated that poor air quality may impact children's health, in particular respiratory health, attendance, and academic performance. Nevertheless, it should be noted that there are other adverse health effects that are less documented. Few data exist for teachers and other adults that work in schools. Allergic individuals seem to be at a higher risk for adverse respiratory health consequences. Air quality improvement represents an important measure for prevention of adverse health consequences in children and adults in schools. PMID:24298914

    Redevelopment of landfill sites in the New Jersey-New York metropolitan area for recreational (golf courses), commercial, and even residential purposes seems to be gaining acceptance among municipal planners and developers. Landfill gas generation, which includes methane and potentially toxic nonmethane compounds usually continues long after closure of the landfill exercise phase. It is therefore prudent to evaluate potential health risks associated with exposure to gas emissions before redevelopment of the landfill sites as recreational, commercial, and, especially, residential properties. Unacceptably high health risks would call for risk management measures such as limiting the development to commercial/recreational rather than residential uses, stringent gas control mechanisms, interior air filtration, etc. A methodology is presented for applying existing models to estimate residual landfill hazardous compounds emissions and to quantify associated health risks. Besides the toxic gas constituents of landfill emissions, other risk-related issues concerning buried waste, landfill leachate, and explosive gases were qualitatively evaluated. Five contiguously located landfill sites in New Jersey intended for residential and recreational redevelopment were used to exemplify the approach. PMID:16869439

    This article examines the effects of children's subjective health status and exposure to residential environmental toxins on academic performance for the first time, while adjusting for school-level effects using generalized estimating equations. The analysis employs National Air Toxics Assessment risk estimates and individual-level data collected through a mail survey. Results indicate that poorer subjective health status and higher levels of residential air toxins are statistically significantly associated with lower grade point averages, meaning that there is an independent effect of air pollution on children's academic achievement that cannot be explained by poor health alone.

    When ambient air quality standards established in the EU Directive 2008/50/EC are exceeded, Member States are obliged to develop and implement Air Quality Plans (AQP) to improve air quality and health. Notwithstanding the achievements in emission reductions and air quality improvement, additional efforts need to be undertaken to improve air quality in a sustainable way - i.e. through a cost-efficiency approach. This work was developed in the scope of the recently concluded MAPLIA project "Moving from Air Pollution to Local Integrated Assessment", and focuses on the definition and assessment of emission abatement measures and their associated costs, air quality and health impacts and benefits by means of air quality modelling tools, health impact functions and cost-efficiency analysis. The MAPLIA system was applied to the Grande Porto urban area (Portugal), addressing PM10 and NOx as the most important pollutants in the region. Four different measures to reduce PM10 and NOx emissions were defined and characterized in terms of emissions and implementation costs, and combined into 15 emission scenarios, simulated by the TAPM air quality modelling tool. Air pollutant concentration fields were then used to estimate health benefits in terms of avoided costs (external costs), using dose-response health impact functions. Results revealed that, among the 15 scenarios analysed, the scenario including all 4 measures lead to a total net benefit of 0.3M€·y(-1). The largest net benefit is obtained for the scenario considering the conversion of 50% of open fire places into heat recovery wood stoves. Although the implementation costs of this measure are high, the benefits outweigh the costs. Research outcomes confirm that the MAPLIA system is useful for policy decision support on air quality improvement strategies, and could be applied to other urban areas where AQP need to be implemented and monitored.

  15. Exploration of health risks related to air pollution and temperature in three Latin American cities

    2013-12-01

    We explore whether the health risks related to air pollution and temperature extremes are spatially and socioeconomically differentiated within three Latin American cities: Bogota, Colombia, Mexico City, Mexico, and Santiago, Chile. Based on a theoretical review of three relevant approaches to risk analysis (risk society, environmental justice, and urban vulnerability as impact), we hypothesize that health risks from exposure to air pollution and temperature in these cities do not necessarily depend on socio-economic inequalities. To test this hypothesis, we gathered, validated, and analyzed temperature, air pollution, mortality and socioeconomic vulnerability data from the three study cities. Our results show the association between air pollution levels and socioeconomic vulnerabilities did not always correlate within the study cities. Furthermore, the spatial differences in socioeconomic vulnerabilities within cities do not necessarily correspond with the spatial distribution of health impacts. The present study improves our understanding of the multifaceted nature of health risks and vulnerabilities associated with global environmental change. The findings suggest that health risks from atmospheric conditions and pollutants exist without boundaries or social distinctions, even exhibiting characteristics of a boomerang effect (i.e., affecting rich and poor alike) on a smaller scale such as areas within urban regions. We used human mortality, a severe impact, to measure health risks from air pollution and extreme temperatures. Public health data of better quality (e.g., morbidity, hospital visits) are needed for future research to advance our understanding of the nature of health risks related to climate hazards.

  20. Urban land use, air toxics and public health: Assessing hazardous exposures at the neighborhood scale

    International Nuclear Information System (INIS)

    Land use data are increasingly understood as important indicators of potential environmental health risk in urban areas where micro-scale or neighborhood level hazard exposure data are not routinely collected. This paper aims to offer a method for estimating the distribution of air toxics in urban neighborhoods using land use information because actual air monitoring data rarely exist at this scale. Using Geographic Information System spatial modeling tools, we estimate air toxics concentrations across neighborhoods in New York City and statistically compare our model with the US Environmental Protection Agency's National Air Toxic Assessment and air monitoring data across three NYC neighborhoods. We conclude that land use data can act as a good proxy for estimating neighborhood scale air toxics, particularly in the absence of monitoring data. In addition, the paper suggests that land use data can expand the reach of environmental impact assessments that routinely exclude analyses of potential exposures to urban air toxics at the neighborhood scale

    Air pollution is among the leading global risks for mortality and responsible for increasing risk for chronic diseases. Community perceptions on exposure are critical in determining people's response and acceptance of related policies. Therefore, understanding people' perception is critical in informing the design of appropriate intervention measures. The aim of this paper was to establish levels and associations between perceived pollution and health risk perception among slum residents. A cross-sectional study of 5,317 individuals aged 35+ years was conducted in two slums of Nairobi. Association of perceived score and individual characteristics was assessed using linear regression. Spatial variation in the perceived levels was determined through hot spot analysis using ArcGIS. The average perceived air pollution level was higher among residents in Viwandani compared to those in Korogocho. Perceived air pollution level was positively associated with perceived health risks. The majority of respondents were exposed to air pollution in their place of work with 66% exposed to at least two sources of air pollution. Less than 20% of the respondents in both areas mentioned sources related to indoor pollution. The perceived air pollution level and related health risks in the study community were low among the residents indicating the need for promoting awareness on air pollution sources and related health risks.

  6. Flows of Air Pollution, Ill Health and Welfare

    International Nuclear Information System (INIS)

    We provide a theoretical framework for measuring welfare when pollution influences economic growth by impairing health and driving up defensive medical expenditures. We demonstrate the usefulness of our framework in practice by applying it to data from Swedish valuation studies designed according to the accounting principles suggested here. We estimate that the negative health effects of nitrogen dioxide emissions amount to 0.6% of GDP in Sweden. We also show that a corrective Pigouvian tax should internalize the direct disutility, reduced labor productivity, and increased healthcare expenditures caused by pollution. According to our calculations, harmful health impacts alone (excluding ecosystem effects) justify 65% of the current Swedish tax on nitrogen dioxide

  9. Health Effects of Indoor Air Pollutants and their Mitigation and Control (invited paper)

    International Nuclear Information System (INIS)

    The nature of chemical, biological and physical contaminants present in indoor air, their sources, and the health effects they cause are reviewed. Among the physical agents, the interaction between tobacco smoke and radon is discussed. Control and improvement of indoor air quality can be achieved combining the use of two main strategies: proper design and construction of buildings, and control of indoor air pollution through source control, ventilation, air cleaning, exposure control, or a combination of them. A number of control measures primarily targeted to pollutants other than radon can also be particularly effective for radon. On the other hand, measures primarily targeted to radon containment can also be beneficial for other pollutants. Effective programmes on indoor air improvement are urgently needed to benefit the health, comfort and productivity of our communities. (author)

  11. Air-conditioning and antibiotics: Demand management insights from problematic health and household cooling practices

    International Nuclear Information System (INIS)

    Air-conditioners and antibiotics are two technologies that have both been traditionally framed around individual health and comfort needs, despite aspects of their use contributing to social health problems. The imprudent use of antibiotics is threatening the capacity of the healthcare system internationally. Similarly, in Australia the increasing reliance on air-conditioning to maintain thermal comfort is contributing to rising peak demand and electricity prices, and is placing an inequitable health and financial burden on vulnerable heat-stressed households. This paper analyses policy responses to these problems through the lens of social practice theory. In the health sector, campaigns are attempting to emphasise the social health implications of antibiotic use. In considering this approach in relation to the problem of air-conditioned cooling and how to change the ways in which people keep cool during peak times, our analysis draws on interviews with 80 Australian households. We find that the problem of peak electricity demand may be reduced through attention to the social health implications of air-conditioned cooling on very hot days. We conclude that social practice theory offers a fruitful analytical route for identifying new avenues for research and informing policy responses to emerging health and environmental problems. - Highlights: • Over-use of antibiotics and air-conditioning has social health implications. • Focusing on financial incentives limits the potential of demand management programs. • Explaining peak demand to households shifts the meanings of cooling practices. • Emphasising the social health implications of antibiotics and air-conditioning may resurrect alternative practices. • Analysing policy with social practice theory offers insights into policy approaches

    The aim of the present study was to determine the effect of postprandial hypertriglyceridemia on the risk of decompression stress following hyperbaric air exposures. The study involved 55 male individuals aged 20-48 years (31.47 ± 5.49 years), body mass index 20.3-33.2 kg/m2 (25.5 ± 2.58 kg/m2). Blood was sampled two hours after a meal each participant had in accordance with individual dietary preferences to determine the following parameters: blood cell counts, activity of aspartate aminotransferase (AST) and alanine ammotransterase (ALT), concentrations of total cholesterol and triglycerides. After each hyperbaric exposure, the presence and intensity of decompression stress were assessed using the Doppler method. Decompression stress was found in 30 individuals. Postprandial hypertriglyceridemia and hypercholesterolemia increased the risk of decompression stress after hyperbaric air exposures. PMID:26742256

    Full Text Available For public health policy and planning it is important to understand the relative contribution of environmental noise on health compared to other environmental stressors. Air pollution is the primary environmental stressor in relation to cardiovascular morbidity and mortality. This paper reports a narrative review of studies in which the associations of both environmental noise and air pollution with health have been examined. Studies of hypertension, myocardial infarction, stroke, mortality and cognitive outcomes were included. Results suggest independent effects of environmental noise from road traffic, aircraft and, with fewer studies, railway noise on cardiovascular outcomes after adjustment for air pollution. Comparative burden of disease studies demonstrate that air pollution is the primary environmental cause of disability adjusted life years lost (DALYs. Environmental noise is ranked second in terms of DALYs in Europe and the DALYs attributed to noise were more than those attributed to lead, ozone and dioxins. In conclusion, in planning and health impact assessment environmental noise should be considered an independent contributor to health risk which has a separate and substantial role in ill-health separate to that of air pollution.

  16. The role of Health Impact Assessment in the setting of air quality standards: An Australian perspective

    International Nuclear Information System (INIS)

    The approaches used for setting or reviewing air quality standards vary from country to country. The purpose of this research was to consider the potential to improve decision-making through integration of HIA into the processes to review and set air quality standards used in Australia. To assess the value of HIA in this policy process, its strengths and weaknesses were evaluated aligned with review of international processes for setting air quality standards. Air quality standard setting programmes elsewhere have either used HIA or have amalgamated and incorporated factors normally found within HIA frameworks. They clearly demonstrate the value of a formalised HIA process for setting air quality standards in Australia. The following elements should be taken into consideration when using HIA in standard setting. (a) The adequacy of a mainly technical approach in current standard setting procedures to consider social determinants of health. (b) The importance of risk assessment criteria and information within the HIA process. The assessment of risk should consider equity, the distribution of variations in air quality in different locations and the potential impacts on health. (c) The uncertainties in extrapolating evidence from one population to another or to subpopulations, especially the more vulnerable, due to differing environmental factors and population variables. (d) The significance of communication with all potential stakeholders on issues associated with the management of air quality. In Australia there is also an opportunity for HIA to be used in conjunction with the NEPM to develop local air quality standard measures. The outcomes of this research indicated that the use of HIA for air quality standard setting at the national and local levels would prove advantageous. -- Highlights: • Health Impact Assessment framework has been applied to a policy development process. • HIA process was evaluated for application in air quality standard setting.

    The presence of polycyclic aromatic hydrocarbons (PAH), mutagens and other air pollutants was investigated in a busy street in central Copenhagen and in a park area adjacent to the street. The winter concentration of benzo(a)pyrene was 4.4+/-1.2 ng/m(3) in the street air and 1.4+/-0.6 ng/m(3) in...... the city park. The atmospheric concentrations of PAH decreased in the order of: street > city background air similar to suburbs > village > open land. The traffic contribution of PAH to street air was estimated to be 90% on working days and 60% during weekends and its contribution to city background...... air was estimated to be 40%. Four different approaches to evaluate the health effects are discussed. The direct effect of PAH air pollution, and other mutagens, is considered to be a maximum of five lung cancer cases each year out of one million people....

  1. Public views on the links between air pollution and health in Northeast England

    International Nuclear Information System (INIS)

    We investigated how public perceptions of the links between air pollution and health varied with contextual factors describing individuals and their locality. Information was collected via postal surveys on 2744 adults resident in five neighborhoods in Northeast England. Perceptions were compared by individual factors (health status, age, and gender) and locality actors (relative deprivation, proximity to industry and district--Teesside r Sunderland, with different amounts of heavy industry). There was relatively little variation in views about air pollution and health links between neighborhoods. The greatest contrasts were found when comparing those living near or further from industry and between the two districts. Any differences were related more to awareness of illness in the neighborhood thought to be affected by air pollution, rather than belief that a particular disease was linked to air pollution. Chronic illness status and age were sometimes found to be associated with perceptions of disease affected by air pollution, but gender and material deprivation were not central to differences in risk perceptions among the population studied. In understanding public perceptions about the links between air quality and health, research should focus on the characteristics of places as well as of people

    Although regular aerobic exercise improves overall health, increased physical activity can lead to heightened exposures to a variety of air pollutants. As such, the cardiovascular health benefits of exercise may be abrogated to some degree by the harmful actions of inhaled pollutants. This review aims to provide an up-to-date summary for health professionals of the cardiovascular responses as well as the risks of exercising in air pollution. Aerobic exercise augments the overall inhaled air pollution dose, potentiates the diffusion of pollutants into circulating blood, and augments oxidative stress and inflammation. The inhalation of particulate matter during exercise can raise blood pressure, impair vascular function, and unfavorably affect autonomic balance. Several studies suggest that air pollutants can increase ischemic symptoms and signs during exercise and can even be capable of impairing exercise performance in some scenarios. The overall evidence supports that the risk-to-benefit ratio generally favors that health care providers continue to strongly encourage their patients to perform regular aerobic exercise. Nevertheless, a greater effort should be made to educate patients about the risks of air pollutant exposures during exercise, particularly those at heightened cardiovascular risk. Although no strategy has been directly tested to reduce morbidity and mortality rate, several prudent actions can be taken to lessen the degree of exposures during exercise which may thereby help mitigate the adverse effects of air pollutants on exercise performance and cardiovascular risk.

    People spend a substantial proportion of their time in traffic. In Europe, the average daily time in traffic is one to one and a half hour. Because of high in-traffic exposures and because most of the journeys are made during rush hours, the one to one and a half hour in traffic contributes disproportionately to total daily exposure to traffic related air pollution. So far a limited number of studies compared particulate matter exposures of different groups of commuters. There is limited evid...

    Active travel (cycling, walking) is beneficial for the health due to increased physical activity (PA). However, active travel may increase the intake of air pollution, leading to negative health consequences. We examined the risk-benefit balance between active travel related PA and exposure to air pollution across a range of air pollution and PA scenarios. The health effects of active travel and air pollution were estimated through changes in all-cause mortality for different levels of active travel and air pollution. Air pollution exposure was estimated through changes in background concentrations of fine particulate matter (PM2.5), ranging from 5 to 200μg/m3. For active travel exposure, we estimated cycling and walking from 0 up to 16h per day, respectively. These refer to long-term average levels of active travel and PM2.5 exposure. For the global average urban background PM2.5 concentration (22μg/m3) benefits of PA by far outweigh risks from air pollution even under the most extreme levels of active travel. In areas with PM2.5 concentrations of 100μg/m3, harms would exceed benefits after 1h 30min of cycling per day or more than 10h of walking per day. If the counterfactual was driving, rather than staying at home, the benefits of PA would exceed harms from air pollution up to 3h 30min of cycling per day. The results were sensitive to dose-response function (DRF) assumptions for PM2.5 and PA. PA benefits of active travel outweighed the harm caused by air pollution in all but the most extreme air pollution concentrations. PMID:27156248

  6. Urban air carcinogens and their effects on health

    Airborne carcinogens may be relevant especially in metropolitan regions with extreme smog as a primary cause of lung cancer. Lung cancer is most common in urban environs and the incidence directly correlates with the size of the city. In addition, several, but not all formal epidemiological studies also suggest a positive correlation between lung cancer incidence and the intensity of air pollution exposure. There is further support for a role of air pollution; as of 1993, 4.4% of all of the bronchogenic adenocarcinoma cancer cases among Mexicans living in industrialized cities are under 40 years of age. It is plausible that chronic inhalation of automobile combustion products, factory emissions, and/or radon is at least partially responsible for the higher incidence of lung cancer exemplified by the never-smoking urban residents. The exceptionally high incidence of lung cancer cases among never-smokers living in highly industrialized Mexican cities offers a unique opportunity to use molecular epidemiology to test whether chronic inhalation of atmospheric pollutants increases the risk for this disease. Overall, the analysis of the genetic alterations in two cancer genes, and possibly the hprt locus should give new insight as to whether the urban never-smokers developed their cancers because of exposure to environmental pollutants.

    The aim of this project is to search for respiratory system particular aggressors to which workers are submitted in their labouring activity. The work plan under the current IAEA contract comprise a prospective study to identify particulate matter deposited in the human respiratory ducts and lung tissue and workers respiratory health status survey at a steel plant, Siderurgia Nacional (SN). So far, the selection of areas of interest at SN, workers exposed, airborne particulate monitoring sites according to the periodicity of labouring cycles, and the beginning of workers medical survey have been achieved and/or initiated. The SN selected area, where steel is processed and steel casting is achieved, involve approximately 80 workers, most of them working at that location for more than 15 years. Blood elemental content data determined by PIXE and INAA and a preliminary health status evaluation from 32 of the 80 workers included in this survey are presented and discussed. (author)

    Exposing children to environmental pollutants during important times of physiological development can lead to long-lasting health problems, dysfunction, and disease. The location of children's schools can increase their exposure. We examined the extent of air pollution from industrial sources around public schools in Michigan to find out whether air pollution jeopardizes children's health and academic success. We found that schools located in areas with the highest air pollution levels had the lowest attendance rates-a potential indicator of poor health-and the highest proportions of students who failed to meet state educational testing standards. Michigan and many other states currently do not require officials considering a site for a new school to analyze its environmental quality. Our results show that such requirements are needed. For schools already in existence, we recommend that their environmental quality should be investigated and improved if necessary. PMID:21543420

    Air quality is a major global concern. Tracking and monitoring air quality provides individuals with the knowledge to make personal decisions about their health and investigate the environment in which they live. Satellite remote sensing and ground-based observations (e.g. Environmental Protection Agency, NASA Aerosol Robotic Network) of air quality is spatially and temporarlly limited and often neglects to provide individuals with the freedom to understand their own personal environment using their personal observations. Given the ubiquitous nature of smartphones, individuals have access to powerful processing and sensing capabilities. When coupled with the appropriate sensor parameters, filters, and algorithms, smartphones can be used both for 'citizen science' air quality applications and 'professional' scientific atmospheric investigations, alike, simplifying data analysis, processing, and improving deployment efficiency. We evaluate the validity of smartphone technology for air quality investigations using standard Cimel CE 318 sun photometry and Fourier Transform Infrared Spectroradiometer (FTIR) observations at specific locations.

    Full Text Available Background: Air pollution in Tehran, capital of Iran is responsible for several diverse negative effects. It has been estab­lished that air pollution can affect human health. These health effects include increased hospital admissions due to the ex­acerba­tion of cardiac and respiratory diseases, as well as symptoms such as headache, cough, eye irritation, nausea, sputum and even death in the most vulnerable individuals. In evaluating any policy that would reduce air pollution, it is useful to com­pare the policy's costs to its benefits expressed in monetary units.Methods: Since there is no market available that places value on the benefits of improved air quality, we must undertake non market valuation methods. In this paper we used direct medical cost (DMC, contingent valuation (CV and value of sta­tisti­cal life (VOSL approaches and household production model of health. According to this study marginal health dam­age costs for the following type of pollutants impacts: sulfur dioxide (SO2, nitrogen dioxide (NO2, particulate matter (PM10 and carbon monoxide (CO are quantified using exposure response functions(ERF which relate pollutant con­centra­tion to the resulting impact on a receptor(health. ERFs for health impacts are derived from epidemiological studies.Results: Health damage costs has been estimated at 16224 US$ per each unit increase of PM10, 28816 US$ per each unit in­crease of CO, 1927 US$ per each unit increase of NO2 and 7739 US$ per each unit increase of SO2.Conclusion: Substituting economic incentives for command and control approach to regulating air quality.

    European air quality legislation has reduced emissions of air pollutants across Europe since the 1970s, affecting air quality, human health and regional climate. We used a coupled composition-climate model to simulate the impacts of European air quality legislation and technology measures implemented between 1970 and 2010. We contrast simulations using two emission scenarios; one with actual emissions in 2010 and the other with emissions that would have occurred in 2010 in the absence of technological improvements and end-of-pipe treatment measures in the energy, industrial and road transport sectors. European emissions of sulphur dioxide, black carbon (BC) and organic carbon in 2010 are 53%, 59% and 32% lower respectively compared to emissions that would have occurred in 2010 in the absence of legislative and technology measures. These emission reductions decreased simulated European annual mean concentrations of fine particulate matter (PM2.5) by 35%, sulphate by 44%, BC by 56% and particulate organic matter by 23%. The reduction in PM2.5 concentrations is calculated to have prevented 80 000 (37 000-116 000, at 95% confidence intervals) premature deaths annually across the European Union, resulting in a perceived financial benefit to society of US232 billion annually (1.4% of 2010 EU GDP). The reduction in aerosol concentrations due to legislative and technology measures caused a positive change in the aerosol radiative effect at the top of atmosphere, reduced atmospheric absorption and also increased the amount of solar radiation incident at the surface over Europe. We used an energy budget approximation to estimate that these changes in the radiative balance have increased European annual mean surface temperatures and precipitation by 0.45 ± 0.11 °C and by 13 ± 0.8 mm yr-1 respectively. Our results show that the implementation of European legislation and technological improvements to reduce the emission of air pollutants has improved air quality and human

  1. Particulate matter and health - From air to human lungs

    International Nuclear Information System (INIS)

    This work reports on the environmental influence in the respiratory health of workers exposed to metal pollutants in their labour activities (metal processing industry). The clinical, respiratory functional and morphological changes were related with blood elemental concentrations in order to evaluate the influence of exposure to inhaled metal airborne particles. In addition, the deposition of particulate matter in the respiratory system was assessed in humans and in an animal model to infer possible mechanisms of interaction of metals with the respiratory tissue. The respiratory affections encountered for the exposure group through clinical, functional and morphological data are related with the number of years of exposure and with high levels of Zn in blood. Methodologies applied have into account the quality of results produced. Interlaboratory checks were carried out using certified reference materials and standard procedures were initiated to assure traceability in chemical analysis of biological matrices using analytical techniques based on X ray spectrometry.

    In both ambient air pollution epidemiology and health impact assessment an accurate assessment of the population exposure is crucial. Although considerable advances have been made in assessing human exposure outdoors, the assessments often do not consider the impact of individual travel behavior on such exposures. Population-based exposures to NO{sub 2} and O{sub 3} using only home addresses were compared with models that integrate all time-activity patterns-including time in commute-for Flanders and Brussels. The exposure estimates were used to estimate the air pollution impact on years of life lost due to respiratory mortality. Health impact of NO{sub 2} using an exposure that integrates time-activity information was on average 1.2% higher than when assuming that people are always at their home address. For ozone the overall estimated health impact was 0.8% lower. Local differences could be much larger, with estimates that differ up to 12% from the exposure using residential addresses only. Depending on age and gender, deviations from the population average were seen. Our results showed modest differences on a regional level. At the local level, however, time-activity patterns indicated larger differences in exposure and health impact estimates, mainly for people living in more rural areas. These results suggest that for local analyses the dynamic approach can contribute to an improved assessment of the health impact of various types of pollution and to the understanding of exposure differences between population groups. - Highlights: Black-Right-Pointing-Pointer Exposure to ambient air pollution was assessed integrating population mobility.

    In both ambient air pollution epidemiology and health impact assessment an accurate assessment of the population exposure is crucial. Although considerable advances have been made in assessing human exposure outdoors, the assessments often do not consider the impact of individual travel behavior on such exposures. Population-based exposures to NO2 and O3 using only home addresses were compared with models that integrate all time-activity patterns—including time in commute—for Flanders and Brussels.

    Brazil, as the largest ethanol exporter in the world, faces rapid expansion of ethanol production due to the increase of global biofuels demand. Current production of Brazilian sugarcane ethanol causes significant air emissions mainly from the open burning phase of agriculture wastes (i.e. sugarcane straws and leaves) resulting in potential health impacts. One possible measure to avoid undesired burning practices is to increase the utilization of unburned sugarcane residues as a feedstock for cellulosic ethanol. To explore the benefits of this substitution, here we first apply a bottom-up approach combining agronomic data and life-cycle models to investigate spatially and temporally explicit emissions from sugarcane waste burning. We further quantify the health benefits from preventing burning practices using the CMAQ regional air quality model and the BenMAP health benefit analysis tool adapted for Brazilian applications. Furthermore, the health impacts will be converted into monetary values which provide policymakers useful information for the development of cellulosic ethanol.

    Carbon dioxide emissions standards for US power plants will influence the fuels and technologies used to generate electricity, alter emissions of pollutants such as sulphur dioxide and nitrogen oxide, and influence ambient air quality and public health. We present an analysis of how three alternative scenarios for US power plant carbon standards could change fine particulate matter and ozone concentrations in ambient air, and the resulting public health co-benefits. The results underscore that carbon standards to curb global climate change can also provide immediate local and regional health co-benefits, but the magnitude depends on the design of the standards. A stringent but flexible policy that counts demand-side energy efficiency towards compliance yields the greatest health benefits of the three scenarios analysed.

  6. Valuing health effects from the industrial air pollution in rural Tianjin,China

    2004-01-01

    High concentrations of air pollutants such as total suspended particulates(TSP) and sulfur dioxide(SO2 ) have serious impacts on nearby populations. In this paper, a survey of rural Tianjin residents' willingness-to-pay for health improvement was reported on, and the MBDC( multiple bounded discrete choice) model was adopted to study the respondents' willingness-to-pay to prevent respiratory illnesses.The results showed that the willingness-to-pay for health improvement was affected by respondents' health condition, work situation and environmental awareness, but not by personal habits, such as smoking. If person's willingness-to-pay to avoid respiratory diseases can be considered equal to the cost to personal health caused by air pollution, the total cost will reach 538 x 106 RMB Yuan( RMB, equal to 65million USD) per year.

  7. Particulate matter and health - from air to human lungs

    International Nuclear Information System (INIS)

    Biological and environmental monitoring was carried out at a steel processing sector of a steel plant in Portugal. Approximately 70 workers were surveyed for their respiratory function and blood elemental contents as indicators for a long-term exposure. The characterisation of chemical elements in air at the workplace was also evaluated taking in account the separation of particles by their aerodynamic diameter. Two fractions were collected, a coarse fraction for particles below 10 μm and above 2 μm, and a fine fraction for particles below 2 μm. PIXE and INAA analytical techniques were used for the determination of blood and aerosol elemental concentrations. Up to 12 elements (Na, Cl, K, Ca, Fe, Cu, Zn, As, Se, Sb, Hg, and Pb) were determined in blood and so far, up to 18 elements for aerosols (e.g., Na, Al Si, S, Cl, K, Ca, Cr, Mn, Fe, Cu, Zn, As, Se, Cd, Sb, Hg, and Pb). The concentrations of the essential elements in blood (e.g., Fe, Zn and Se) were found to be altered relative to a reference Portuguese group constituted by non-exposed persons. Relative to the blood average elemental contents for As, Sb, Hg and Pb, the levels determined were below maximum permissible concentrations or reference values, except for Pb. Nevertheless, concentrations above maximum limit values were determined for some of the surveyed subjects. There are evidences that the levels of Se, Cu, and Sb in blood are influenced by exposure. Also, living habits (smoking and other activities) and pulmonary affections may modulate As, Pb and Zn concentrations in blood. For all the chemical elements identified in the particulate matter of the working atmosphere the limit values indicated in the Portuguese regulation were not exceeded, except for Fe. (author)

  8. Air pollution and its impact on human health in mega cities

    International Nuclear Information System (INIS)

    One of the major problems faced by the over crowded mega-cities of the world in general and that in third world is the alarming levels of air pollution causing damage to the health of its inhabitants. In Cairo estimated lives lost annually due to air pollution varies between 4000 to 16000 while Delhi has been rated as the most polluted city in the world. Karachi now a mega-city typically represents pollution status of the third world. Major cause of pollution is more than 0.62 millions vehicles on the roads. The pollution due to industries is localized and mainly affects the health of the workers. Measurement carried out for the selected areas along the roads carrying high density traffic show a very high pollution level (CO, 3 to 10 ppm; CO/sub 2/,170 to 350 ppm; HC 0.274 to 0.360 vol. %; particulate matter 67.0 to 565.5 ug/m/sup 3/. A parallel hospital survey to correlate air borne disease with air pollution indicates that over 16600 to 22977 patients suffered from air borne diseases while 6377 from bacterial infection. Analysis showed that 70% of the patients suffering from airborne disease come from the surveyed areas with high level pollution. Cancer is shifting from old age to middle age group indicating deteriorating air environment. Ratio of male to female patients is 2:1, which is indicative of hazardous ambient air quality outside to which men are exposed more than women. The paper discusses in depth the air pollution and its impact on human health in mega cities with Karachi as a case study. (author)

    Full Text Available Deteriorating air quality in China has created global public health concerns in regard to health and health-related behaviors. Although emerging environmental regulations address ambient air pollution in China, the level of enforcement and long-term impact of these measures remain unknown. Exposure to air pollution has been shown to lead to multiple adverse health outcomes, including increased rates of heart disease and mortality. However, a lesser-known but increasingly significant concern is the relationship between air pollution and its effects on outdoor exercise. This is especially important in China, which has a culturally rooted lifestyle that encourages participation in outdoor physical activity. This article evaluates the intersection of air pollution and outdoor exercise and provides a discussion of issues related to its public health impact in China, where efforts to promote a healthy lifestyle may be adversely affected by the ambient air pollution that has accompanied rapid economic development and urbanization.

    Indoor air quality effects on human health are of increasing concern to public health agencies and building owners. The prevention and treatment of 'sick building' syndrome and the spread of air-borne diseases in hospitals, for example, are well known priorities. However, increasing attention is being directed to the vulnerability of our public buildings/places, public security and national defense facilities to terrorist attack or the accidental release of air-borne biological pathogens, harmful chemicals, or radioactive contaminants. The Indoor Air Nuclear, Biological, and Chemical Health Modeling and Assessment System (IA-NBC-HMAS) was developed to serve as a health impact analysis tool for use in addressing these concerns. The overall goal was to develop a user-friendly fully functional prototype Health Modeling and Assessment system, which will operate under the PNNL FRAMES system for ease of use and to maximize its integration with other modeling and assessment capabilities accessible within the FRAMES system (e.g., ambient air fate and transport models, water borne fate and transport models, Physiologically Based Pharmacokinetic models, etc.). The prototype IA-NBC-HMAS is designed to serve as a functional Health Modeling and Assessment system that can be easily tailored to meet specific building analysis needs of a customer. The prototype system was developed and tested using an actual building (i.e., the Churchville Building located at the Aberdeen Proving Ground) and release scenario (i.e., the release and measurement of tracer materials within the building) to ensure realism and practicality in the design and development of the prototype system. A user-friendly "demo" accompanies this report to allow the reader the opportunity for a "hands on" review of the prototype system's capability.

    Studies have shown that reducing exposure to triggers such as air pollutants can reduce symptoms and the need for medication in asthma patients. However, systems that track asthma are generally not integrated with those that track environmental hazards related to asthma. Tlvs lack of integration hinders public health awareness and responsiveness to these environmental triggers. The current study is a collaboration between health and environmental professionals to utilize NASA-derived environmental data to develop a decision support system (DSS) for asthma prediction, surveillance, and intervention. The investigators link asthma morbidity data from the University of Mississippi Medical Center (UMMC) and Mississippi Department of Health (MDH) with air quality data from the Mississippi Department of Environmental Quality (MDEQ) and remote sensing data from NASA. Daily ambient environmental hazard data for PM2.5 and ozone are obtained from the MDEQ air quality monitoring locations and are combined with remotely sensed data from NASA to develop a state-wide spatial and time series profile of environmental air quality. These data are then used to study the correlation of these measures of air quality variation with the asthma exacerbation incidence throughout the state over time. The goal is to utilize these readily available measures to allow real-time risk assessment for asthma exacerbations. GeoMedStat, a DSS previously developed for biosurveillance, will integrate these measures to monitor, analyze and report the real-time risk assessment for asthma exacerbation throughout the state.

  17. Development of a health effects based priority ranking system for air emissions reductions from oil refineries in Canada

    International Nuclear Information System (INIS)

    This paper presents the concept and methodologies behind the development of a health effects priority ranking tool for the reduction of air emissions from oil refineries. The Health Effects Indicators Decision Index- Versions 2 (Heidi II) was designed to assist policy makers in prioritizing air emissions reductions on the basis of estimated risk to human health. Inputs include facility level rankings of potential health impacts associated with carcinogenic air toxics, non-carcinogenic air toxics and criteria air contaminants for each of the 20 refineries in Canada. Rankings of estimated health impacts are presented on predicted incidence of health effects. Heidi II considers site-specific annual pollutant emission data, ambient air concentrations associated with releases and concentration response functions for various types of health effects. Additional data includes location specific background air concentrations, site-specific population densities, and the baseline incidence of different health effects endpoints, such as cancer, non-cancer illnesses and cardiorespiratory illnesses and death. Air pollutants include the 29 air toxics reported annually in Environment Canada's National Pollutant Release Inventory. Three health impact ranking outputs are provided for each facility: ranking of pollutants based on predicted number of annual cases of health effects; ranking of pollutants based on simplified Disability Adjusted Life Years (DALYs); and ranking of pollutants based on more complex DALYs that consider types of cancer, systemic disease or types of cardiopulmonary health effects. Rankings rely on rough statistical estimates of predicted incidence rates for health endpoints. The models used to calculate rankings can provide useful guidance by comparing estimated health impacts. Heidi II has demonstrated that it is possible to develop a consistent and objective approach for ranking priority reductions of air emissions. Heidi II requires numerous types and

    Southwest Memphis is a residential region surrounded by fossil fuel burning, steel, refining, and food processing industries, and considerable mobile sources whose emissions may pose adverse health risks to local residents. This study characterizes cancer and non-cancer risks resulting from exposure to ambient air toxics in southwest Memphis. Air toxics samples were collected at a central location every 6 days from June 5, 2008 to January 8, 2010. Volatile organic compounds (VOCs) were collected in evacuated stainless-steel canisters and aldehydes by DNPH cartridges, and samples were analyzed for 73 target compounds. A total of 60 compounds were detected and 39 were found in over 86% of the samples. Mean concentrations of many compounds were higher than those measured in many industrial communities throughout the U.S. The cumulative cancer risk associated with exposure to 13 carcinogens found in southwest Memphis air was 2.3 × 10-4, four times higher than the national average of 5.0 × 10-5. Three risk drivers were identified: benzene, formaldehyde, and acrylonitrile, which contributed 43%, 19%, and 14% to the cumulative risk, respectively. This is the first field study to confirm acrylonitrile as a potential risk driver. Mobile, secondary, industrial, and background sources contributed 57%, 24%, 14%, and 5% of the risk, respectively. The results of this study indicate that southwest Memphis, a region of significant income, racial, and social disparities, is also a region under significant environmental stress compared with surrounding areas and communities.

    Full Text Available Abstract Background Socio-economic status, smoking, and exposure to increased levels of environmental air pollution are associated with adverse effects on respiratory health. We assessed the contribution of occupational exposures, smoking and outdoor air pollution as competing factors for the association between socio-economic status and respiratory health indicators in a cohort of women from the Ruhr area aged 55 at the time of investigation between 1985 and 1990. Methods Data of 1251 women with spirometry and complete questionnaire information about respiratory diseases, smoking and potential confounders were used in the analyses. Exposure to large-scale air pollution was assessed with data from monitoring stations. Exposure to small-scale air pollution was assessed as traffic-related exposure by distance to the nearest major road. Socio-economic status was defined by educational level. Multiple regression models were used to estimate the contribution of occupational exposures, smoking and outdoor air pollution to social differences in respiratory health. Results Women with less than 10 years of school education in comparison to more than 10 years of school education were more often occupationally exposed (16.4% vs. 10.1%, smoked more often (20.3% vs. 13.9%, and lived more often close to major roads (26.0% vs. 22.9%. Long-term exposure to increased levels of PM10 was significantly associated with lower school education. Women with low school education were more likely to suffer from respiratory symptoms and had reduced lung function. In the multivariate analysis the associations between education and respiratory health attenuated after adjusting for occupational exposure, smoking and outdoor air pollution. The crude odds ratio for the association between the lung function indicator FEV1 less than 80% of predicted value and educational level (10 years of school education was 1.83 (95% CI: 1.22–2.74. This changed to 1.56 (95% CI: 1.03–2

    2015-12-01

    Satellite remote sensing of the environment offers a unique vantage point that can fill in the gaps of environmental, spatial, and temporal data for tracking disease. Health and Air Quality providers and researchers are effective by the global environmental changes that are occurring and they need environmental data to study and understand the geographic, environmental, and meteorological differences in disease. This presentation maintains a diverse constellation of Earth observing research satellites and sponsors research in developing satellite data applications across a wide spectrum of areas including environmental health; infectious disease; air quality standards, policies, and regulations; and the impact of climate change on health and air quality. Successfully providing predictions with the accuracy and specificity required by decision makers will require advancements over current capabilities in a number of interrelated areas. These areas include observations, modeling systems, forecast development, application integration, and the research to operations transition process. This presentation will highlight many projects on which NASA satellites have been a primary partner with local, state, Federal, and international operational agencies over the past twelve years in these areas. Domestic and International officials have increasingly recognized links between environment and health. Health providers and researchers need environmental data to study and understand the geographic, environmental, and meteorological differences in disease. The presentation is directly related to Earth Observing systems and Global Health Surveillance and will present research results of the remote sensing environmental observations of earth and health applications, which can contribute to the health research. As part of NASA approach and methodology they have used Earth Observation Systems and Applications for Health Models to provide a method for bridging gaps of environmental

    Gruhl, J.; Schweppe, F.C.

    1980-01-01

    This project involves several tasks designed to take advantage of a very extensive air pollution monitoring system that is operating in the Chestnut Ridge region of Western Pennsylvania and the very well developed analytic dispersion models that have been previously fine-tuned to this particular area. The major task in this project is to establish, through several distinct epidemiologic approaches, health data to be used to test hypotheses about relations of air pollution exposures to morbidity and mortality rates in this region. This project affords a cost-effective opportunity for state-of-the-art techniques to be used in both costly areas of air pollution and health effects data collection. The closely spaced network of monitors, plus the dispersion modeling capabilities, allow for the investigation of health impacts of various pollutant gradients in neighboring geographic areas, thus minimizing the confounding effects of social, ethnic, and economic factors. The pollutants that are monitored in this network include total gaseous sulfur, sulfates, total suspended particulates, NOx, NO, ozone/oxidants, and coefficient of haze. In addition to enabling the simulation of exposure profiles between monitors, the air quality modeling, along with extensive source and background inventories, will allow for upgrading the quality of the monitored data as well as simulating the exposure levels for about 25 additional air pollutants. Another important goal of this project is to collect and test the many available models for associating health effects with air pollution, to determine their predictive validity and their usefulness in the choice and siting of future energy facilities.

    International Nuclear Information System (INIS)

    The total impact of air pollution on human health is not well understood. This workshop examined key policy issues concerning air quality, and the availability of models and analyses to inform decision-makers. Attendants included stakeholders from health and environment departments of municipal, provincial and federal governments, as well as academics, consulting firms, industry and non-governmental organizations. The complexity of computer-based models was identified as a significant barrier to the development of a better understanding of the impacts of air pollution on human health, and it was noted that most models are not equipped to deal with the various levels of policy and decision-making that occur across many jurisdictions. It was observed that there is also a lack of data. It was suggested that efficient and cost-effective models are needed to identify good policy options, as well as tools that maximize the integration of information in a comprehensive manner. Evaluations of the impacts of air pollution should occur within the broad context of public health and consider both social and interactive needs. Continuing stakeholder dialogue was recommended, as well as a more in-depth exploration of policy analysis tools. A national meeting was planned to build on conclusions from the workshop. A guidance document was proposed to provide best practices to guide non-experts on health impacts, the interpretation of monitoring results, and the selection of models and appropriate analyses. Case studies of issues facing municipalities concerning planning and land use decisions were recommended, as well as various actions to mitigate the effects of poor air quality and greenhouse gas (GHG) emissions. Five presentations were given, followed by breakout sessions and discussions. refs., tabs., figs

  9. Core public health functions for BC : evidence review : air quality-indoor

    International Nuclear Information System (INIS)

    Indoor sources of pollutants can have a major impact on the health of Canadians, as pollutant concentrations are often higher indoors than outdoors. This paper assessed data compiled by public health indoor air interventions. The aim of the study was to identify the current state of evidence on the impacts of indoor pollution in order to develop performance improvement plans for public health programs in British Columbia (BC). The literature review used several databases to review interventions involving humidity control; ventilation; particulate matter; indoor allergens; and environmental tobacco smoke. Results of the review showed that improving inadequate ventilation can significantly decrease the prevalence of sick building syndrome as well as other self-reported symptoms attributed to indoor air pollution. A review of the literature also demonstrated that many building ventilation systems are not functioning to design specifications. The poor quality of studies on the health impacts of particulate matter or dust made it difficult to fully assess the benefits of particle filtration on human health. Studies investigating the impacts of controlling indoor allergens suggested that the avoidance of dust mites may benefit people with allergies. Evidence gained from studies on environmental tobacco smoke showed that banning or restricting smoking will reduce the burden of illness from pollutants in indoor air. 20 refs., 3 tabs

    To investigate the effect of ambient air pollution on human health and the subsequent disability-adjusted life years (DALYs) lost in Shanghai. Methods We used epidemiology-based exposure-response functions to calculate the attributable number of cases due to air pollution in Shanghai in 2000, and then we estimated the corresponding DALYs lost in Shanghai based on unit DALYs values of the health consequences. Results Ambient air pollution caused 103 064 DALYs lost in Shanghai in 2000. Among all the health endpoints, premature deaths and chronic bronchitis predominated in the value of total DALYs lost. Conclusion The air pollution levels have an adverse effect on the general population health and strengthen the rationale for limiting the levels of air pollution in outdoor air in Shanghai.

  13. The health risks of incense use in the home: an underestimated source of indoor air pollution?

    Science.gov (United States)

    Roberts, Debbie; Pontin, David

    2016-03-01

    The health impact of indoor air pollution is a growing area of interest for public health professionals. People typically spend up to 90 per cent of their time indoors, particularly women, young children and elders. Although the adverse health effects of second-hand tobacco smoke are well recognised, the impact of burning incense in the home has received little attention in Western literature. Incense burning in the home is common in a number of cultures (particularly Asian, North African or Arabic). Many health visitors (HVs) work with communities who use incense regularly for religious/cultural reasons and it is a neglected area of study and research.The literature suggests that home incense use can have significant adverse health effects, particularly on cardiopulmonary morbidity and mortality. Further research is needed to identify which individuals are most susceptible, which types of incense are most harmful, and whether any actions can be taken to minimise exposure. PMID:27111977

  14. Fuel combustion, air pollution exposure, and health: The situation in developing countries

    International Nuclear Information System (INIS)

    There are a number of recent studies of air pollution in developing-country cities, each of necessity relying heavily on the one available source of comparative international ambient monitoring data, Global Environment Monitoring System (GEMS). In this review, therefore, rather than simply reproduce the GEMS data. The author chose to examine developing-country air pollution from the standpoint of a useful analysis technique that has been under development in recent years: Basically the review is composed of four parts: (1) a brief description of the historical and current relationship between energy use and air pollution; (2) an explanation of the idea of exposure assessment and the power that it can bring to analyses of the health impacts of air pollution; (3) focusing on developing countries, a global exposure assessment, combining demographic data with GEMS outdoor data and less-developed country (LDC) indoor air-monitoring studies; (4) a review of the health effects literature relevant to the micro-environments found to harbor the largest human exposures. 104 refs

    SAVIAH is an EC-funded methodological study coordinated by Dr. Paul Elliott at the LSHTM (London School of Hygiene and Tropical Medicine). The project aims to apply, test and evaluate new and emerging methodologies in the fields of epidemiology, geography, air pollution modelling and small area health statistics, and to bring the data together in a consistent geographic framework. The study was carried out in the U.K., The Netherlands, Poland and the Czech Republic, using the example of childhood wheeze and outdoor air pollution. Specific aims of the study were, in each centre, (1) to carry out a questionnaire survey among parents of guardians of around 4000 to 5000 children aged between 7 and 11, (2) to carry out a series of air pollution surveys for NO{sub 2} as a proxy for the complex of traffic-related pollutants, and SO{sub 2} (PL), using a dense network of passive samplers, (3) to build up a detailed Geographical Information System (GIS) for each of the study areas; (4) to construct an air pollution `map` based on the NO{sub 2} and SO{sub 2} measurements and a health `map` based on `map smoothing` techniques and (5) to explore methods to examine relationships between health, pollution, socio-economic and other data.

  16. Exposure-response functions for health effects of air pollutants based on epidemiological findings

    Energy Technology Data Exchange (ETDEWEB)

    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

    Aggravated air pollution in Beijing, China has caused serious health concern. This paper comprehensively evaluates the health losses from illness and premature death caused by air pollution in monetary terms. We use the concentration of PM10 as an indicator of the pollution since it constitutes the primary pollutant in Beijing. By our estimation, air pollution in Beijing caused a health loss equivalent to Ұ583.02 million or 0.03 % of its GDP. Most of the losses took the form of depreciation in human capital that resulted from premature death. The losses from premature deaths were most salient for people of either old or young ages, with the former group suffering from the highest mortality rates and the latter group the highest per capital losses of human capitals from premature death. Policies that target on PM10 emission reduction, urban vegetation expansion, and protection of vulnerable groups are all proposed as possible solutions to air pollution risks in Beijing.

    Most ice resurfacing machines used in indoor ice arenas have internal combustion engines. They use either propane or petrol as fuel. The main exhaust pollutants are carbon monoxide (CO), nitrogen oxides (NO{sub x}), volatile organic compounds (VOC) and fine particles. In general, propane engines emit more NO{sub x} than petrol engines, but their CO emissions are smaller. The levels of these pollutants in indoor air depend on total amount of emissions volume of arena and effectiveness of ventilation. However, due to large variations in engine emissions the air quality in any single arena cannot be estimated without direct measurements. High levels of CO and nitrogen dioxide (NO{sub 2}) have been measured in indoor ice arenas of North America since 1960`s, and it is only recently that high NO{sub 2} levels have been measured also in Sweden. In health studies, attention has been paid mostly to epidemic acute poisonings among ice hockey players and spectators caused by large concentrations of CO. However, some cases of acute NO{sub 2} poisonings have also been described. The aims of this project are: (1) to examine the air quality in Finnish indoor ice arenas, (2) to study associations between the air quality and the major technical features of the arenas, (3) to assess personal exposures of ice hockey players, spectators and maintenance personnel to CO and NO{sub 2}, (4) to investigate short-term and longer-term health effects of CO and NO{sub 2} exposures on ice hockey players and maintenance personnel, (5) to inform the managers of ice arenas and the health authorities on the current air quality problems and health risks in Finnish indoor ice arenas.

    Full Text Available Abstract Background Greenhouse gas (GHG mitigation policies can provide ancillary benefits in terms of short-term improvements in air quality and associated health benefits. Several studies have analyzed the ancillary impacts of GHG policies for a variety of locations, pollutants, and policies. In this paper we review the existing evidence on ancillary health benefits relating to air pollution from various GHG strategies and provide a framework for such analysis. Methods We evaluate techniques used in different stages of such research for estimation of: (1 changes in air pollutant concentrations; (2 avoided adverse health endpoints; and (3 economic valuation of health consequences. The limitations and merits of various methods are examined. Finally, we conclude with recommendations for ancillary benefits analysis and related research gaps in the relevant disciplines. Results We found that to date most assessments have focused their analysis more heavily on one aspect of the framework (e.g., economic analysis. While a wide range of methods was applied to various policies and regions, results from multiple studies provide strong evidence that the short-term public health and economic benefits of ancillary benefits related to GHG mitigation strategies are substantial. Further, results of these analyses are likely to be underestimates because there are a number of important unquantified health and economic endpoints. Conclusion Remaining challenges include integrating the understanding of the relative toxicity of particulate matter by components or sources, developing better estimates of public health and environmental impacts on selected sub-populations, and devising new methods for evaluating heretofore unquantified and non-monetized benefits.

    Full Text Available The increases in air pollution over the metropolitan cities are a threat to human health and environment. An attempt has been made to evaluate the health consequences of indoor air pollution induced by Beam Rolling Mills Factory at Ahwaz (Iran. A questionnaire was prepared to obtain information on health of 481 workers, out of which 200 each were selected from exposed and non-exposed category by stratified randomized method. Fisher exact test and chi-square test were used to calculate the values. The study concludes that more than 80% of the workers have high exposure risk to diseases. Analysis of the health impacts reveals that exposed workers are more prone to various diseases as compared to the non-exposed workers. It is also observed that exposure to air pollutants might be the causative factor for various diseases among the smokers but also nonsmoking workers. The analysis also reveals that there is higher relative risk in occupational fatigue and cardio-vascular disease. Further, the study found that percentage of workers having various diseases is much higher in the indoor environment as compared to the outdoor environment

    Full Text Available Objectives: The World Health Organization (WHO provides data on national indices of health, environment and economy. When we were asked, why air pollution is negatively correlated with cancer mortality, our first response (presumably the mortality data are not age-adjusted was not sufficient to explain the paradox. Material and Methods: A table including all-cause, cancer and childhood mortality, life expectancy, gross national product per person, smoking prevalence, physician density and particulate matter (PM10 per country (N = 193 was developed. For explorative purposes weighted cross-sectional multiple linear regressions models were built. Results: Air pollution is positively correlated with infant and overall mortality and negatively with life expectancy. This might not only depict a true causal effect of PM10 because air quality is also an indicator of a country’s prosperity and general state of environment. Cancer mortality is negatively correlated with PM10. However, this association turns positive when economic or health system indicators are controlled. Conclusions: The World Health Organization’s world-wide data sets demonstrate the large disparity of our world. A careful and professional approach is needed as interpretation is difficult, especially for lay persons. Therefore, with publicly available data WHO should also provide interpretation and guidance.

  3. Health and Cellular Impacts of Air Pollutants: From Cytoprotection to Cytotoxicity

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Air pollution as one of the ravages of our modern societies is primarily linked to urban centers, industrial activities, or road traffic. These atmospheric pollutants have been incriminated in deleterious health effects by numerous epidemiological and in vitro studies. Environmental air pollutants are a heterogeneous mixture of particles suspended into a liquid and gaseous phase which trigger the disruption of redox homeostasis—known under the term of cellular oxidative stress—in relation with the establishment of inflammation and cell death via necrosis, apoptosis, or autophagy. Activation or repression of the apoptotic process as an adaptative response to xenobiotics might lead to either acute or chronic toxicity. The purpose of this paper is to highlight the central role of oxidative stress induced by air pollutants and to focus on the subsequent cellular impacts ranging from cytoprotection to cytotoxicity by decreasing or stimulating apoptosis, respectively.

    Solid fuel cookstoves are used heavily in rural China for both residential cooking and heating purposes. Their use contributes significantly to regional emissions of several key pollutants, including carbon monoxide, volatile organic compounds, oxides of nitrogen, and aerosol particles. The residential sector was responsible for approximately 36%, 46% and 81% of China's total primary PM2.5, BC and OC emissions respectively in 2005 (Lei et al., 2011). These emissions have serious consequences for household air pollution, ambient air quality, tropospheric ozone formation, and the resulting population health and climate impacts. This paper presents initial findings from the modeling component of a multi-disciplinary energy intervention study currently being conducted in Sichuan, China. The purpose of this effort is to quantify the impact of residential cooking and heating emissions on regional air quality and human health. Simulations with varying levels of residential emissions have been carried out for the whole of 2014 using the Weather Research and Forecasting model with Chemistry (WRF-Chem), a fully-coupled, "online" regional chemical transport model. Model output is evaluated against surface air quality measurements across China and compared with seasonal (winter and summer) ambient air pollution measurements conducted at the Sichuan study site in 2014. The model output is applied to available exposure—response relationships between PM2.5 and cardiopulmonary health outcomes. The sensitivity in different regions across China to the different cookstove emission scenarios and seasonality of impacts are presented. By estimating the mortality and disease burden risk attributable to residential emissions we demonstrate the potential benefits from large-scale energy interventions.

    Full Text Available We carried out bibliographic searches in PubMed and Embase.com for the period from 1996 to 2008 with the aim of reviewing the scientific literature on the relationship between various sources of indoor air pollution and the respiratory health of children under the age of five. Those studies that included adjusted correlation measurements for the most important confounding variables and which had an adequate population size were considered to be more relevant. The results concerning the relationship between gas energy sources and children's respiratory health were heterogeneous. Indoor air pollution from biomass combustion in the poorest countries was found to be an important risk factor for lower respiratory tract infections. Solvents involved in redecorating, DYI work, painting, and so forth, were found to be related to an increased risk for general respiratory problems. The distribution of papers depending on the pollution source showed a clear relationship with life-style and the level of development.

    Rotating shiftwork is common for air traffic controllers and usually causes sleep deprivation, biological adaptations, and life changes for these workers. This study assessed quality of life, the sleep, and the health of 30 air traffic controllers employed at an international airport in Brazil. The objective was to identify health and quality of life concerns of these professionals. The results identified physical inactivity, overweight, excess body fat, low scores for physical and social relationships, and sleep deprivation for workers in all four workshifts. In conclusion, these workers are at risk for chronic non-transmittable diseases and compromised work performance, suggesting the need for more rest time before working nightshifts and work environments that stimulate physical activity and healthy diets.

    2014-12-01

    Full Text Available Expanding traditional time geography, this study examines personal exposure to air pollution and personal pollutant intake, and defines personal health danger zones by accounting for individual level space-time behavior. A 3D personal air pollution and health risk map is constructed to visualize individual space-time path, personal Air Quality Indexes (AQIs, and personal health danger zones. Personal air pollution exposure level and its variation through space and time is measured by a portable air pollutant sensor coupled with a portable GPS unit. Personal pollutant intake is estimated by accounting for air pollutant concentration in immediate surroundings, individual’s biophysical characteristics, and individual’s space-time activities. Personal air pollution danger zones are defined by comparing personal pollutant intake with air quality standard; these zones are particular space-time-activity segments along an individual’s space-time path. Being able to identify personal air pollution danger zones can help plan for proper actions aiming at controlling health impacts from air pollution. As a case study, this paper reports on an examination and visualization of an individual’s two-day ozone exposure, intake and danger zones in Houston, Texas.

    Significant areas of the Brazilian Amazon have been deforested over the past few decades, with fire being the dominant method through which forests and vegetation are cleared. Fires emit large quantities of particulate matter into the atmosphere, degrading air quality and negatively impacting human health. Since 2004, Brazil has achieved substantial reductions in deforestation rates and associated deforestation fires. Here we assess the impact of this reduction on air quality and human health. We show that dry season (August - October) aerosol optical depth (AOD) retrieved by satellite over southwest Brazil and Bolivia is positively related to Brazil's annual deforestation rate (r=0.96, Pdeforestation rates compared to years with low deforestation rates, suggesting regional air quality is degraded substantially by fire emissions associated with deforestation. This link is further demonstrated by the positive relationship between observed AOD and satellite-derived particulate emissions from deforestation fires (r=0.89, Pdeforestation have reduced regional dry season mean surface particulate matter concentrations by ~30%. Using concentration response functions we estimate that this reduction in particulate matter may be preventing 1060 (388-1721) premature adult mortalities annually across South America. Future increases in Brazil's deforestation rates and associated fires may threaten the improved air quality reported here.

    Nowadays the modelling of systems in high resolution is being used for air quality and other forecasting applications, where a spatial area is related with different interrelated variables that could be displayed on a map. This area is usually represented by global domains (hundred to thousand of square km); when smaller regions need to be represented, a high resolution modelling system can be used, these systems goes from one square km to dozen of square km, health is on...

    Many recent studies suggest that urban air pollution, especially thoracic particles (PM{sub 10}), are associated with increased respiratory, mortality and morbidity at lower levels than what has previously been known. During the Finnish winter, the dust formed from asphalt ware by studded auto tyres, street sanding and combustion processes is accumulated on the snow. In the spring, when the snow melts from the streets, part of this dust is resuspended by traffic and wind. This creates spring dust episodes, during which TSP and PM{sub 10} levels exceed air quality guidelines in most Finnish cities. The mechanisms through which PM{sub 10} produces its health effects are largely unknown. It has been suggested that the number of particles, especially that of very small particles in the nanometer range, would be as important as the mass or the chemical composition of the particles. In most previous studies, the particles measured have mostly composed of combustion products. There are only sparse data on the size distribution of particles in the Finnish spring dust episode and no studies on it`s possible health effects. The aim of the PEACE project was to develop a common protocol for research on the short-term relationship between respiratory health and changes in air pollution levels. The present report describes the design and preliminary results of Finnish field work of the PEACE study that was carried out in Kuopio, Eastern Finland. (author)

    Full Text Available Background: Air pollution is an important contributor to respiratory disease in children. Objective: To examine associations between household reporting of childhood respiratory conditions and household characteristics related to air pollution in Alaska Native communities. Design: In-home surveys were administered in 2 rural regions of Alaska. The 12-month prevalence of respiratory conditions was summarized by region and age. Odds ratios (ORs were calculated to describe associations between respiratory health and household and air quality characteristics. Results: Household-reported respiratory health data were collected for 561 children in 328 households. In 1 region, 33.6% of children aged <5 years had a recent history of pneumonia and/or bronchitis. Children with these conditions were 2 times more likely to live in a wood-heated home, but these findings were imprecise. Resident concern with mould was associated with elevated prevalence of respiratory infections in children (ORs 1.6–2.5, while reported wheezing was associated with 1 or more smokers living in the household. Reported asthma in 1 region (7.6% was lower than national prevalence estimates. Conclusions: Findings suggest that there may be preventable exposures, including wood smoke and mould that affect childhood respiratory disease in these rural areas. Additional research is needed to quantify particulate matter 2.5 microns in aerodynamic diameter or less and mould exposures in these communities, and to objectively evaluate childhood respiratory health.

    Air pollution worldwide has been associated with cardiovascular and respiratory morbidity and mortality, particularly in urban settings with elevated concentrations of primary pollutants. Air pollution is a very complex mixture of primary and secondary gases and particles, and its potential to cause harm can depend on multiple factors-including physical and chemical characteristics of pollutants, which varies with fine-scale location (e.g., by proximity to local emission sources)-as well as local meteorology, topography, and population susceptibility. It has been hypothesized that the intake of anti-oxidant and anti-inflammatory nutrients may ameliorate various respiratory and cardiovascular effects of air pollution through reductions in oxidative stress and inflammation. To date, several studies have suggested that some harmful effects of air pollution may be modified by intake of essential micronutrients (such as B vitamins, and vitamins C, D, and E) and long-chain polyunsaturated fatty acids. Here, we review the existing literature related to the potential for nutrition to modify the health impacts of air pollution, and offer a framework for examining these interactions. PMID:26690474

    Full Text Available This study aims to value air quality from the urban housing market in Yogyakarta City. It is also provides estimation of marginal willingness to pay for the air quality improvement and estimation of the consumer surplus due to reduce of air quality. The methodological framework for estimation is based on a hedonic price model. The result of hedonic price method concludes that by adopting a two-stage estimation procedure to estimate the relationship between air quality and property value, on the average, an increase in the level of O3 by one percent will increases the property price by 0.063 percent. By using a health production function and demand function mitigation can be seen that the medical history of the individual has effect on the number of working days lost. Meanwhile, O3 pollution has positive effect on the amount of medical expenses for mitigation. Decreasing in O3 pollution causes a decrease in the level of medical expenses to mitigate. Therefore, it is important to reduce the negative impacts of air pollution.

  7. Development of a health-based air quality index for Canada : public opinion research 2004-05 : final report

    International Nuclear Information System (INIS)

    Canadians rely on an air quality indexes (AQIs) to inform them about air pollution conditions in their communities. However, there is no AQI common to all of Canada, and there is a lack of consistency in the way in which air quality is calculated and reported, as well as in the use of health-based messages. This paper reported findings of a public opinion research survey conducted to gauge Canadians' awareness, perceptions and behavioural responses to air quality, air pollution and AQIs. The aim of the study was to guide the development of health messages to more effectively communicate the AQI to Canadians with respect to the health risks associated with poor air quality. Telephone surveys were conducted immediately following a poor air quality episode to measure the public's awareness and response to these events, as well as residents' general awareness and use of AQIs. A separate research project was then conducted which consisted of in-depth qualitative interviews with 28 individuals recruited from the general population. A comprehensive national telephone survey was then conducted following the summer 2004 'smog season', which focused on the public's awareness of air pollution and AQIs. Results from the first 2 phases of the research were then presented at a workshop comprised of health and environmental communities specializing in air issues in Canada. Focus groups were then held to test public reaction to new AQI communications concepts derived from the research. Results indicated that Canadians widely identify air pollution as a significant environmental problem. However, the information from AQIs had a limited impact in terms of prompting actions to reduce personal exposure. A new type of national AQI for Canada was developed that conveyed information on air quality conditions and their significance. Key features include a 0 to 10 point unbounded scale showing current air quality conditions; a forecast of future conditions; standardized information

    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

    In recent years several regulations and standards for air quality and limits for air pollution were issued or are in preparation by the European Union, which have severe influence on the environmental monitoring and legislation in Austria. This chapter of the environmental control report of Austria gives an overview about the legal situation of air pollution control in the European Union and in specific the legal situation in Austria. It gives a comprehensive inventory of air pollution measurements for the whole area of Austria of total suspended particulates, ozone, volatile organic compounds, nitrogen oxides, sulfur dioxide, carbon monoxide, heavy metals, benzene, dioxin, polycyclic aromatic hydrocarbons and eutrophication. For each of these pollutants the measured emission values throughout Austria are given in tables and geographical charts, the environmental impact is discussed, statistical data and time series of the emission sources are given and legal regulations and measures for an effective environmental pollution control are discussed. In particular the impact of fossil-fuel power plants on the air pollution is analyzed. (a.n.)

    Full Text Available Problem statement: Air pollution in Kazakhstan is significant environmental problem. The air pollution level of cities and industrial centers remains rather high. The highest level of air pollution is registered in Ridder, Ust-Kamenogorsk, Almaty, Zyryanovsk, Aktau, Atyrau, Shymkent, Taraz, Petropavlovsk and Temirtau. The enterprises of the Rudnyi Altay, Pavlodar Oblast and enterprises of oil and gas complex in West-Kazakhstan, Atyrau and Mangistau Oblasts play the negative role in air pollution. About one third of industrial enterprises have no sanitary protective zones of standard sizes. A considerable part of the population of industrial centers live in the zone of a direct impact of harmful industrial factors emissions of polluting substances into the air, noise, vibration, electrical magnet fields and other physical factors (Dahl et al., 2001; Kaiser and Pulsipher, 2007; Farmer and Farmer, 2000. Under the conditions of the air polluter impact there is high morbidity and mortality from cardio-vascular diseases, respiratory disease, nervous system and sensory organ disturbances, gastrointestinal disease and circulatory disease. Poor air quality has been cited as a factor in these conditions (Jensena et al., 1997; Namazbaeva et al., 2010. Then we provide details a correlation between the level of disease of malignant tumors and the emissions from stationary sources in Rudnyi Altay industrial area. To reveal the quantitative relationship between the disease of malignant tumors and the change in the quantity of emissions was carried out regression analysis and model. Regression analysis and model confirms a significant direct correlation between the incidence of malignant tumors and the amount of emissions from stationary sources (correlation coefficient R = 0,6. Analysis of vital statistics revealed the increased disease rate. Conclusion: Health status of the populations is negatively affected by the unfavorable environmental

    Air pollution originating from road traffic is a known risk factor of respiratory and cardiovascular disease (both in terms of chronic and acute effects). While adverse effects on cardiovascular health have also been linked with noise (after controlling for air pollution), noise exposure has been commonly linked to sleep impairment and negative emotional reactions. Health is multi-faceted, both conceptually and operationally; Health-Related Quality of Life (HRQOL) is one of many measures capable of probing health. In this study, we examine pre-collected data from postal surveys probing HRQOL obtained from a variety of urban, suburban, and rural contexts across the North Island of New Zealand. Analyses focus on the covariance between air pollution annoyance and noise annoyances, and their independent and combined effects on HRQOL. Results indicate that the highest ratings of air pollution annoyance and noise annoyances were for residents living close to the motorway, while the lowest were for rural residents. Most of the city samples indicated no significant difference between air pollution- and noise-annoyance ratings, and of all of the correlations between air pollution- and noise-annoyance, the highest were found in the city samples. These findings suggest that annoyance is driven by exposure to environmental factors and not personality characteristics. Analysis of HRQOL indicated that air pollution annoyance predicts greater variability in the physical HRQOL domain while noise annoyance predicts greater variability in the psychological, social and environmental domains. The lack of an interaction effect between air pollution annoyance and noise annoyance suggests that air pollution and noise impact on health independently. These results echo those obtained from objective measures of health and suggest that mitigation of traffic effects should address both air and noise pollution. PMID:27509512

    A key policy challenge in Indian megacities is to curb high concentrations of PM2.5 and mitigate associated adverse health impacts. Using the Greenhouse Gases and Air Pollution Interactions and Synergies (GAINS) model we carry out an integrated analysis of the air quality regulations across different sectors for the city of Delhi. Our findings show that PM2.5 concentrations for Delhi will not reach the recommended national ambient air quality standards (NAAQS) even by 2030 under the current policies scenario. Adopting advanced control technologies reduces PM2.5 concentrations by about 60% and all-cause mortality by half in 2030. Climate change mitigation policies significantly reduce greenhouse gases, but have a modest impact on reducing PM2.5 concentrations. Stringent policies to control the net flow of air pollution from trans-boundary sources will play a crucial role in reducing pollution levels in Delhi city. Achieving NAAQS requires a stringent policy portfolio that combines advanced control technologies with a switch to cleaner fuels and the control of trans-boundary pollution.

    Already in the 1960s a lot of cross-sectional studies were conducted to determine the effects of air-pollution on respiratory diseases or symptoms of children. According to the then dominating type of air-pollution, effects of SO{sub 2} and TSP were mainly studied. Usually SO{sub 2} and TSP were highly correlated and their effects could not be separated satisfactorily. Such a high correlation was not seen when comparing annual mean concentrations in different towns of East and West Germany in 1989. The range of SO{sub 2} values was from 20 to 310 g/m{sup 3} whereas the range of TSP was narrower, from 65 to 123 {mu}g/m{sup 3} In 1991 therefore a study was started to compare the effects of different types and amounts of air pollution on children`s health. The results of the first cross-sectional study, in 1991, were presented at the 9{sup th} World Clean Air Congress. It was found that airway diseases and respiratory symptoms were clearly related to the SO{sub 2} pollution load. This was not true for allergic manifestations. Since 1990 there is a considerable reduction of SO{sub 2} pollution in East Germany. The aim of this presentation is to show that the associations which had been found on an spatial scale can be seen on an temporal scale, too. (author)

    A variety of potential effects on human health resulting from climate change have been identified in several assessments. According to an international panel{sup 1} they include direct effects of extreme temperatures on cardiovascular deaths, secondary effects due to vector-borne diseases or crop yields, and tertiary effects such as those that might arise from conflicts over freshwater supplies. To this fist we add the secondary effects of increased air pollution, which may result either directly from climate change or indirectly from increased air conditioning loads and the corresponding pollutant emissions from electric utilities. Higher ozone concentrations have been linked to increased ambient temperatures by both theory and observations of monitoring data. A similar association with particulate matter has been limited to observations, thus far. The pollution-heat linkage has been recognized before` but health effects have not been evaluated in terms of predictions of the joint effects of both agents. This paper has been prepared in two sections. First, we discuss the ozone situation with special reference to the Northeast Corridor and New York. In the second section, we present estimates of the health effects of climate change on New York and discuss some mitigation options.

    Understanding and quantifying outdoor and indoor sources of human exposure are essential but often not adequately addressed in health-effects studies for air pollution. Air pollution epidemiology, risk assessment, health tracking and accountability assessments are examples of health-effects studies that require but often lack adequate exposure information. Recent advances in exposure modeling along with better information on time-activity and exposure factors data provide us with unique opportunities to improve the assignment of exposures for both future and ongoing studies linking air pollution to health impacts. In September 2006, scientists from the US Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) along with scientists from the academic community and state health departments convened a symposium on air pollution exposure and health in order to identify, evaluate, and improve current approaches for linking air pollution exposures to disease. This manuscript presents the key issues, challenges and recommendations identified by the exposure working group, who used cases studies of particulate matter, ozone, and toxic air pollutant exposure to evaluate health-effects for air pollution. One of the over-arching lessons of this workshop is that obtaining better exposure information for these different health-effects studies requires both goal-setting for what is needed and mapping out the transition pathway from current capabilities to meeting these goals. Meeting our long-term goals requires definition of incremental steps that provide useful information for the interim and move us toward our long-term goals. Another over-arching theme among the three different pollutants and the different health study approaches is the need for integration among alternate exposure assessment approaches. For example, different groups may advocate exposure indicators, biomonitoring, mapping methods (GIS), modeling, environmental media

    Full Text Available I participated in a NATO Advanced Research Workshop titled “Effects of Air Pollution on Forest Health and Biodiversity in Forests of the Carpathian Mountains,” in Stara Lesna, Slovakia from May 22–26, 2001. Researchers from Canada, Czech Republic, Poland, Romania, Slovakia, Ukraine, and the U.S. met to present their results from a three-year cooperative study of tree health and air quality monitoring in forests of the Carpathian Mountains in Central Europe. Much of the work reported related to assessing the crown condition of trees in permanent plots in natural or managed (planted forests in the mountains. The endpoint was tree condition, with results extrapolated to the forests in the Carpathian range. From this I learned that, of the 50,000 trees evaluated, European beech (Fagus sylvatica was the most healthy, while Norway spruce (Picea abies (the principal forest tree and white fir (Abies alba sustained crown defoliation of up to 12.8%. The cause of this crown defoliation and tree decline was usually attributed to “air pollution” as a generic term and an automatic assumption. It is well known that deposition of heavy metals and acidic sulfur and nitrogen compounds can cause tree decline and predispose affected trees to bark beetles and climatic damage. Chemical analyses can also be done to detect metals and sulfur compounds in trees and soils. Sometimes these analyses were done, but most often the assumption was that crown defoliation was caused by air pollution. The assumption was that given sufficient exposure to high enough concentrations of toxic elements, sooner or later there will be a visible adverse response.

    Full Text Available We use regional air quality modeling to evaluate the impact of model resolution on uncertainty associated with the human health benefits resulting from proposed air quality regulations. Using a regional photochemical model (CAMx, we ran a modeling episode with meteorological inputs simulating conditions as they occurred during August through September 2006 (a period representative of conditions leading to high ozone, and two emissions inventories (a 2006 base case and a 2018 proposed control scenario, both for Houston, Texas at 36, 12, 4 and 2 km resolution. The base case model performance was evaluated for each resolution against daily maximum 8-h averaged ozone measured at monitoring stations. Results from each resolution were more similar to each other than they were to measured values. Population-weighted ozone concentrations were calculated for each resolution and applied to concentration response functions (with 95% confidence intervals to estimate the health impacts of modeled ozone reduction from the base case to the control scenario. We found that estimated avoided mortalities were not significantly different between the 2, 4 and 12 km resolution runs, but the 36 km resolution may over-predict some potential health impacts. Given the cost/benefit analysis requirements motivated by Executive Order 12866 as it applies to the Clean Air Act, the uncertainty associated with human health impacts and therefore the results reported in this study, we conclude that health impacts calculated from population weighted ozone concentrations obtained using regional photochemical models at 36 km resolution fall within the range of values obtained using fine (12 km or finer resolution modeling. However, in some cases, 36 km resolution may not be fine enough to statistically replicate the results achieved using 2, 4 or 12 km resolution. On average, when modeling at 36 km resolution, an estimated 5 deaths per week during the May through September ozone

  5. Effects of NATO air-raids on human environment and health of the population of Serbia

    International Nuclear Information System (INIS)

    The bombing targets of NATO forces were almost all larger towns in Serbia, and particularly the facilities of chemical and oil industry. The most severely attacked cities were Pancevo, Novi Sad, Belgrade, Nis, Kragujevac, Sombor, Krusevac, Bogutovac, Kraljevo, Smederevo, Bor, Prahovo, etc. Constantly and repeatedly attacked chemical and oil plants, in addition to direct destruction of the plants, produced divergent effects, such as emission of a variety of primary and secondary pollutants into the living environment (air, water, soil). The majority of these pollutants are documented to have not only the toxicological but also the potential carcinogenic, teratogenic and/or mutagenic effects. The activities of health service (preventive before all) included qualitative and, to a permissible extent, the quantitative measurements of the mineral oils, polychlorobiphenyls, polycyclic aromatic carbons, total carbons, phenol, 3-chloroethylene and tetrachloroethylene, benzene, toluene, xylene, ethylbenzene, styrene, phosgene, vinyl chloride monomer, 1 ,2-dichlor-oethane, dioxin, furan, toxic metals (lead, chromium, cadmium, nickel, arsenic, mercury) -first in air, then in water currents, soil, plants and animals. The peacetime networks for monitoring environmental pollution (air, water, foodstuffs) were not capable to follow up all changes that occurred during aggression. During bombing of the chemical and oil plants the health service did not register any significant increase of individuals (dwellers) presenting with accident-related signs and symptoms. The results of environmental quality obtained so far, indicate a need to follow up the subclinical and clinical manifestations of a long-term exposure of the population. However, the majority of substances that we were able to identify indicate the presence of environmental pollution which will persist for a long time in the years ahead and in concentrations which may eventually have toxicological, carcinogenic, mutagenic

    Full Text Available Background: China has become an aging society, and the mental health problem of the elderly is increasingly becom-ing prominent. This paper aimed to analyze the effect of air pollution and rural-urban difference on mental health of the elderly in China.Methods: Using the data from the China Health and Retirement Longitudinal Survey (CHARLS, 2013, after control-ling the social demography variable via Tobit and Probit, a regression analysis of the effect of air pollution and rural-urban difference on mental health and psychological disorder was conducted on 6,630 old people (≧60 yr old of Chi-na from February to April 2015. Mental health and psychological disorder of the elderly were measured by the CES-D score of respondents. Air pollution degree of counties and cities (n=123 were measured by SO2 emission.Results: 27.8% of old people had psychological disorders. Air pollution significantly influenced the mental health of the elderly, showing a positive “U-shaped” curve (P<0.001. In China, the urban elderly had better psychological sta-tus than the rural elderly had. The female elderly had more serious mental health problems. Marriage, education, and social activities had positive effects on the mental health of the elderly.Conclusion: China’s local governments should consider the influence of air pollution on the mental health of the elderly during economic development. This paper recommends paying attention to the difference in mental health between the urban and rural elderly when making public health policies. Governments could improve the mental health of the elderly by enriching social activities and increasing employment opportunities of the elderly.

  8. Low-carbon energy policy and ambient air pollution in Shanghai, China: A health-based economic assessment

    International Nuclear Information System (INIS)

    Energy and related health issues are of growing concern worldwide today. To investigate the potential public health and economic impact of ambient air pollution under various low-carbon energy scenarios in Shanghai, we estimated the exposure level of Shanghai residents to air pollution under various planned scenarios, and assessed the public health impact using concentration-response functions derived from available epidemiologic studies. We then estimated the corresponding economic values of the health effects based on unit values for each health outcome. Our results show that ambient air pollution in relation to low-carbon energy scenarios could have a significant impact on the future health status of Shanghai residents, both in physical and monetary terms. Compared with the base case scenario, implementation of various low-carbon energy scenarios could prevent 2804-8249 and 9870-23,100 PM10-related avoidable deaths (mid-value) in 2010 and 2020, respectively. It could also decrease incidence of several relevant diseases. The corresponding economic benefits could reach 507.31-1492.33 and 2642.45-6192.11 million U.S. dollars (mid-value) in 2010 and 2020, respectively. These findings illustrate that a low-carbon energy policy will not only decrease the emission of greenhouse gases, but also play an active role in the reduction of air pollutant emissions, improvement of air quality, and promotion of public health. Our estimates can provide useful information to local decision-makers for further cost-benefit analysis

    This study adopted an integrated 'source-to-receptor' assessment paradigm in order to determine the effects of emissions from passenger transport on urban air quality and human health in the megacity, Delhi. The emission modeling was carried out for the base year 2007 and three alternate (ALT) policy scenarios along with a business as usual (BAU) scenario for the year 2021. An Activity-Structure-Emission Factor (ASF) framework was adapted for emission modeling, followed by a grid-wise air quality assessment using AERMOD and a health impact assessment using an epidemiological approach. It was observed that a 2021-ALT-III scenario resulted in a maximum concentration reduction of ~24%, ~42% and ~58% for carbon monoxide (CO), nitrogen dioxide (NO2) and particulate matter (PM), respectively, compared to a 2021-BAU scenario. Further, it results in significant reductions in respiratory and cardiovascular mortality, morbidity and Disability Adjusted Life Years (DALY) by 41% and 58% on exposure to PM2.5 and NO2 concentrations when compared to the 2021-BAU scenario, respectively. In other words, a mix of proposed policy interventions namely the full-phased introduction of the Integrated Mass Transit System, fixed bus speed, stringent vehicle emission norms and a hike in parking fees for private vehicles would help in strengthening the capability of passenger transport to cater to a growing transport demand with a minimum health burden in the Delhi region. Further, the study estimated that the transport of goods would be responsible for ~5.5% additional VKT in the 2021-BAU scenario; however, it will contribute ~49% and ~55% additional NO2 and PM2.5 concentrations, respectively, in the Delhi region. Implementation of diesel particulate filters for goods vehicles in the 2021-ALT-IV-O scenario would help in the reduction of ~87% of PM2.5 concentration, compared to the 2021-BAU scenario; translating into a gain of 1267 and 505 DALY per million people from exposure to PM2.5 and NO

    Central ventilation and air conditioner systems are widely utilized nowadays in public places for air exchange and temperature control,which significantly influences the transfer of pollutants between indoors and outdoors.To study the effect of central ventilation and air conditioner systems on the concentration and health risk from airborne pollutants,a spatial and temporal survey was carried out using polycyclic aromatic hydrocarbons (PAHs) as agent pollutants.During the period when the central ventilation system operated without air conditioning (AC-off period),concentrations of 2-4 ring PAHs in the model supermarket were dominated by outdoor levels,due to the good linearity between indoor air and outdoor air (rp > 0.769,p < 0.05),and the slopes (1.2-4.54) indicated that ventilating like the model supermarket increased the potential health risks from low molecular weight PAHs.During the period when the central ventilation and air conditioner systems were working simultaneously (AC-on period),although the total levels of PAHs were increased,the concentrations and percentage of the particulate PAHs indoors declined significantly.The BaP equivalency (BaPeq concentration indicated that utilization of air conditioning reduced the health risks from PAHs in the model supermarket.

    The objective of the study is to examine the impact of environmental indicators and air pollution on "health" and "wealth" for the low-income countries. The study used a number of promising variables including arable land, fossil fuel energy consumption, population density, and carbon dioxide emissions that simultaneously affect the health (i.e., health expenditures per capita) and wealth (i.e., GDP per capita) of the low-income countries. The general representation for low-income countries has shown by aggregate data that consist of 39 observations from the period of 1975-2013. The study decomposes the data set from different econometric tests for managing robust inferences. The study uses temporal forecasting for the health and wealth model by a vector error correction model (VECM) and an innovation accounting technique. The results show that environment and air pollution is the menace for low-income countries' health and wealth. Among environmental indicators, arable land has the largest variance to affect health and wealth for the next 10-year period, while air pollution exerts the least contribution to change health and wealth of low-income countries. These results indicate the prevalence of war situation, where environment and air pollution become visible like "gun" and "bullet" for low-income countries. There are required sound and effective macroeconomic policies to combat with the environmental evils that affect the health and wealth of the low-income countries. PMID:26493298

  14. Health risks from indoor air pollutants: public alarm and toxicological reality

    International Nuclear Information System (INIS)

    The air, particularly the indoor air, contains a considerable burden of unwanted pollution. Overall there may be thousands of pollutants. They are brought in with the outside air or are generated from or within buildings. Most will be present in minute amounts but several will be present in measurable quantities. The reaction of people to the components of this pollution has little to do with toxicological assessment but is more concerned with political responses and media scares. The health effects from exposure to the very low levels commonly found in the indoor environment of materials such as combustion products, whether from coal, petrol or tobacco or to lead or asbestos fibres, are probably negligible but we worry about them. On the other hand, gases such as carbon monoxide or nitrogen dioxide which are not infrequently present in dangerous concentrations, many solvents and dust-generating DIY projects cause little concern. The distinction between concern and indifference is made without reference to any toxicological knowledge. Although it is certainly prudent, through source control, design and ventilation of buildings, to reduce all pollutants to the lowest level, concentrating on media favourites rather than more important dangers, including disease transmission, may well be a poor use of resources.

    Full Text Available Indoor air quality (IAQ has been the object of several studies due to its adverse health effects on children. Methods. A cross-sectional comparative study was carried out among Malay children in Balakong (2 studied preschools and Bangi (2 comparative preschools, Selangor, with the aims of determining IAQ and its association with respiratory health. 61 and 50 children aged 5-6 years were selected as studied and comparative groups. A questionnaire was used to obtain an exposure history and respiratory symptoms. Lung function test was carried out. IAQ parameters obtained include indoor concentration of particulate matter (PM, volatile organic compounds (VOCs, carbon monoxide (CO, carbon dioxide (CO2, temperature, air velocity (AV, and relative humidity. Results. There was a significant difference between IAQ in studied and comparative preschools for all parameters measured (P<0.001 except for CO2 and AV. Studied preschools had higher PM and CO concentration. FVC, FEV1, FVC% and FEV1% predicted values were significantly lower among studied group. Exposures to PM, VOCs, and CO were associated with wheezing. Conclusion. The finding concluded that exposures to poor IAQ might increase the risk of getting lung function abnormality and respiratory problems among study respondents.

  16. Assessment of health benefits from controlling air pollution in Shanghai, China

    International Nuclear Information System (INIS)

    The large urban centers of the industrializing countries of the world are experiencing severe air quality problems as their demands for energy increase faster than their ability to afford strong environmental protection. This situation is particularly true in the fast-growing part of Asia, where coal often provides the fuel for power generation and industrial development and where the transportation sector grows unchecked. This paper describes the development of an integrated assessment of urban air quality and mitigation options for the city of Shanghai, China. First, a sector-specific, gridded inventory of emissions of SO(sub 2), NO(sub x), and particulate matter (PM) is developed. PM is divided into three size categories (TSP, PM(sub 10), and PM(sub 2.5)) and split into carbonaceous and mineral classes. The URBAT model, a non-steady-state Lagrangian puff model, and related techniques are used to determine the spatial distribution of ambient concentrations of primary and secondary pollutant species. Damage functions are developed to determine the effects of these levels on human health in the greater Shanghai area. Two control scenarios are developed (for power generation and industry), and their effects on emissions of each species are estimated. The health benefits of the control measures are determined, and their relative costs are calculated. The result is a rudimentary cost-benefit analysis that can be used by urban and environmental planners as a guide for determining the relative effectiveness of taking different courses of action

  17. Comments on the discussion of health effects, air pollution and emissions of diesel particulates

    International Nuclear Information System (INIS)

    Since many years diesel particulates are an important topic in public and political discussions on health effects of automotive emissions. Up to now lung cancer was the main issue but recently also toxicological impacts of environmental particles in general are gaining in importance. Some studies indicate that health could be especially affected by the very small particles and their number concentration. Mass related concentration is therefore scrutinized as responsible dose measure. All intensive toxicologic and epidemiologic scientific research activities in the past decades could not supply to date a reliable causative evidence of a hazardous potential of diesel particles for humans- neither inhalation experiments with rats nor epidemiologic studies. Also a quantitative risk assessment is not possible. The level of air pollution is determined by the emission of several sources, however emission from road traffic is generally not the main contributor for particles in the environment. The emission behaviour of advanced diesel technologies with high pressure injection is obviously improved concerning mass and number of particles when compared to conventional diesel engines. Increases of particle number emission or an unfavourable shift of the size distribution could not be realized. Considerations about suitable measures to improve air quality should take into account all main sources and should be guided by cost benefit viewpoints, too. (orig.)

    Roughly 15% of the Brazilian Amazon was deforested between 1976 and 2010. Fire is the dominant method through which forests and vegetation are cleared. Fires emit large quantities of particulate matter into the atmosphere, which degrades air quality and affects human health. Since 2004, Brazil has achieved substantial reductions in deforestation rates and associated deforestation fires. Here we assess the impact of this reduction on air quality and human health during non-drought years between 2001 and 2012. We analyse aerosol optical depth measurements obtained with satellite and ground-based sensors over southwest Brazil and Bolivia for the dry season, from August to October. We find that observed dry season aerosol optical depths are more than a factor of two lower in years with low deforestation rates in Brazil. We used a global aerosol model to show that reductions in fires associated with deforestation have caused mean surface particulate matter concentrations to decline by ~30% during the dry season in the region. Using particulate matter concentration response functions from the epidemiological literature, we estimate that this reduction in particulate matter may be preventing roughly 400 to 1,700 premature adult deaths annually across South America.

    Outdoor air quality and its associated impacts on respiratory problems in Florida are of public health significance. Air quality in Florida can be poor during the extended wildfire season, threatening persons with compromised respiratory systems each year. Studies have demonstrated that particulate matter, which is generally elevated in the vicinity of wildfires, is associated with increases in hospital admissions and occurrences of acute asthma exacerbations. However, few studies have examined the modifying effect of socio-demographic characteristics of cities or regional areas on the relationship between air quality and health outcomes. In an ongoing university/multi-agency project, asthma hospital/emergency room (patient) data are being used to create a health outcome indicator of human response to environmental air quality. Environmental data are derived from satellite measurements, with special attention being given to the effect of wildfires and prescribed burns on air quality. This presentation will focus on the environmental data sets particulate matter, location of fires, smoke plumes that are being collected and processed for linkage with health data. After this linkage has been performed, space-time models of asthma rates as a function of air quality data and socio-demographic variables will be developed and validated. The Florida Department of Health (FDOH) will work with county health department staff and representatives from the medical community to establish a protocol with triggers for issuing public health advisories/alerts based on the developed and validated health outcome indicators. From this effort, a science-based policy for issuing public health advisories/alerts for asthma relating to air quality will be developed, giving FDOH the ability to (1) predict, with stated levels of uncertainty, case load of hospital admissions based on air quality, (2) reduce asthma exacerbations by forewarning asthmatics to limit outside activities on poor air

    Fire is one of the most significant instruments of land use change; forests and grasslands are burned to create and maintain agricultural fields or other anthropogenic landscapes. Although fire emissions have been studied for their climatic and atmospheric effects, less is known about their impact on global public health. In this study, we combine satellite-derived fire emissions and atmospheric modeling to estimate exposure in Southeast Asia to particulate matter and ozone, which have a demonstrated detrimental health impact. Regional emissions can vary by a factor of twenty or more interannually due to the combined influence of prolonged drought conditions from El Nino, land use policies, and high fuel loads in tropical forests and peat. High fire years in the region, such as the 1997-1998 El Nino, can have a profound effect on global trace gas and aerosol loads. We conducted daily simulations of surface fine particulate matter and ozone concentrations for the 1997-2007 period using the Global Fire Emissions Database (GFEDv2) within two atmospheric models: Harvard’s GEOS-CHEM and the NASA GISS Global Climate Model. The results from each model are compared and validated by field-based and remote sensing datasets. The public health risk from each pollutant is assessed with current air quality regulations published by the World Health Organization (WHO). Our preliminary results demonstrate that regions experiencing substantial fire activity can increase the percentage of days per year exceeding WHO air quality guidelines by more than 20%. These anomalies are localized in regions close to burning centers, and more so for heavier pollutants like particulate matter. In addition, the population exposed to particulate matter and ozone above WHO guidelines can increase during high fire years by up to 70% and 50% over the decadal mean, respectively. Our results implicate fires as a serious public health risk to cardiovascular diseases, which the WHO estimates are a

    The quality of our environment and especially air quality is a hot topic in any urban environment. Hourly air quality data tend to be easily available to the populations either in the news or on mobile phones. Studies underlining the relationship between environment and health exist in developed countries, but the results cannot be used in such different environmental and sociological contexts as the ones we have in China. In collaboration with the CNRS, students from the Lycée Français de Shanghai (LFS- 5th and 2nd grade) undertake a study in order to obtain an empiric relationship between the atmospheric pollutants they are exposed to in and out the classrooms, and their own health. This study is a part of a scientific and educational project including Beijing, and possibly other foreign schools in Asia later on. The atmospheric pollution in China is essentially caused by particles from different sizes mainly coming from coal combustion. First, in order to quantify the pollution at Shanghai, the students are recording information regarding fine particles as PM2.5 and PM1.0, NO2, SO2, and O3 using active and passive sensors indoors and outdoors, within the school campus. CO2, temperature and relative humidity are used to qualify the confinement rate indoors. In parallel, approximately 100 students (chosen regarding their age, health records, residence time in China…) and some teachers are going to complete a monthly survey regarding their health. Moreover, they will perform some specific measurements to obtain their breathing performances by spirometry, and an indication of the inflammation of their lower airways by exhaled NO measurements. The protocol of these experimentations and the first results will be presented in the poster. At the end of the project, these results will allow us to get a better knowledge about the air pollution we are exposed to, within the school campus, which will help us to adopt an optimized risk management protocol when pollution

  3. 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 Exposure to air pollution, especially from particulate matter, is generally accepted to be one of the most important public health problems in Europe and worldwide. The effects caused in the general population are associated with relatively small relative risks, but if the ubiquity of exposure is considered, the attributable number of events is large. Furthermore, there is evidence that the effects in sensitive population subgroups (such as the elderly, those with chronic diseases and children are stronger. Within large European Union funded collaborative projects (such as the Air Pollution and Health: a European Approach-APHEA, effect modification by geographical characteristics has been investigated and it was found that in warmer countries, in locations where particles come from traffic and where the proportion of the elderly is greater, particle toxicity is increased. These characteristics are particularly relevant to Southern European locations. From other projects we know that meteorological, climatic, environmental and socioeconomic factors are effect modifiers of the effects of specific air pollutants. In this presentation we will show the evidence on the short-term health effects of particulate and gaseous air pollutants and emphasize particularly results concerning southern Europe and potential effect modifiers. The gaps in knowledge and the need to study air pollution in Southern European countries more extensively will be demonstrated. To conduct useful research, good quality air pollution and health data are needed.

    The InVS published its first results on the Nine-City Air and Health Surveillance Programme (PSAS-9) in March 1999. This phase I pointed out that it was possible for various specialists in the field of air pollution and health to gather around a common set of problems. They also found a link between the daily variations of all the urban air pollution indicators and the total, cardio-vascular and respiratory mortality which, based on French data, contributed to strengthen scientific knowledge in this field. Today's report presents the results of phase Il of the PSAS-9 programme which essentially aimed at assessing the short-term exposure-risk relationships between pollution indicators and hospital admission indicators. This second phase also allowed to confirm the results of phase I on the short-term effect of air pollution on mortality thanks to longer periods of study. Exploratory analysis using new indicators and sensitivity analysis on the pertinence of results were also conducted. Finally, methodological tools were developed in order to optimise data collection and statistical modelization. All these results enabled the quantification of the short-term health impact of air pollution on the PSAS-9 cities. PSAS-9 is now an ongoing epidemiological surveillance programme on the effects of urban air pollution on health, providing information tools to decision-makers and the general population. (author)

    After high-level disinfection of gastrointestinal endoscopes, they are hung to dry in order to prevent residual water droplets impact on patient health. To allow for quick drying and clinical reuse, some endoscopic units use a high pressure air jet (HPAJ) to remove the water droplets on the endoscopes. The purpose of this study was to evaluate the excessive noise exposure with the use of HPAJ in endoscopic preparation room and to investigate the risk to occupational health. Noise assessment was taken during 7 automatic endoscopic reprocessors (AERs) and combined with/without HPAJ use over an 8-hour time-weighted average (TWA). Analytical procedures of the NIOSH and the ISO for noise-induced hearing loss were estimated to develop analytic models. The peak of the noise spectrum of combined HPAJ and 7 AERs was significantly higher than that of the 7 AERs alone (108.3 ± 1.36 versus 69.3 ± 3.93 dBA, P  2.5 dB) was 2.15% at 90 dBA, 11.6% at 95 dBA, and 51.3% at 100 dBA. The odds ratio was 49.1 (95% CI: 11.9 to 203.6). The noise generated by the HPAJ to work over TWA seriously affected the occupational health and safety of those working in an endoscopic preparation room. PMID:25710009

    Full Text Available Abstract Background There is growing epidemiological evidence that short-term and long-term exposure to high levels of air pollution may increase cardiovascular morbidity and mortality. In addition, epidemiological studies have shown an association between air pollution exposure and respiratory health. To what extent the association between cardiovascular mortality and air pollution is driven by the impact of air pollution on respiratory health is unknown. The aim of this study was to investigate whether respiratory health at baseline contributes to the effects of long-term exposure to high levels of air pollution on cardiovascular mortality in a cohort of elderly women. Method We analyzed data from 4750 women, aged 55 at the baseline investigation in the years 1985–1994. 2593 of these women had their lung function tested by spirometry. Respiratory diseases and symptoms were asked by questionnaire. Ambient air pollution exposure was assessed by the concentrations of NO2 and total suspended particles at fixed monitoring sites and by the distance of residency to a major road. A mortality follow-up of these women was conducted between 2001 and 2003. For the statistical analysis, Cox' regression was used. Results Women with impaired lung function or pre-existing respiratory diseases had a higher risk of dying from cardiovascular causes. The impact of impaired lung function declined over time. The risk ratio (RR of women with forced expiratory volume in one second (FEV1 of less than 80% predicted to die from cardiovascular causes was RR = 3.79 (95%CI: 1.64–8.74 at 5 years survival time and RR = 1.35 (95%CI: 0.66–2.77 at 12 years. The association between air pollution levels and cardiovascular death rate was strong and statistically significant. However, this association did only change marginally when including indicators of respiratory health into the regression analysis. Furthermore, no interaction between air pollution and respiratory health

    Poor indoor air quality has been linked to the exacerbation of asthma symptoms in children. Because people spend most of their time indoors, improving indoor air quality may provide some relief to asthma sufferers. A study was conducted to assess whether operating an air cleaning/ventilating unit (HEPAiRx {sup registered}) in a child's bedroom can improve his/her respiratory health. Thirty children diagnosed with asthma were randomly split into two groups. For the first six weeks, group A had the air cleaning/ventilating unit (HEPAiRx {sup registered}) running in the bedrooms of the participants and group B did not; for the second six weeks, both groups had the cleaners running in the bedrooms; and, for the final six weeks, group A turned the cleaners off and group B kept theirs running. Indoor air quality parameters, including temperature, relative humidity, particulate matter (PM 0.5-10 {mu}m), carbon monoxide, carbon dioxide and total volatile organic compound (TVOC) concentrations, were monitored in each bedroom using an AirAdvice indoor air quality multi-meter. As a measure of pulmonary inflammation, exhaled breath condensate (EBC) was collected every sixth day and analyzed for nitrate and pH. Peak expiratory flow (PEF) was also measured. PM and TVOC concentrations decreased with operation of the HEPAiRx an average of 72% and 59%, respectively. The EBC nitrate concentrations decreased significantly and the EBC pH and PEF values increased significantly with operation of the unit (p < 0.001 when comparing on/off sample means). These results indicate that air cleaning in combination with ventilation can effectively reduce symptoms for asthma sufferers. (author)

    This was an empirically based assessment of non-prior service students' quality of life in the Air Force's School of Health Care Sciences. Analysis provided five results: (1) The overall quality of life at the school was good. (2) The variables accounting for student unhappiness were dormitory unsuitability and the students not being in their top-three career choices. (3) Structural changes were required at the dormitories. (4) The desire to succeed and how to achieve that success were the most important interests for students. (5) Loved ones and student independence were the greatest indicators of motivation. The findings resulted in three immediate corrections and two long-term recommendations to improve students' quality of life. The two long-term recommendations were to have an educational psychologist intervene when students are having significant learning problems, and to alter the selection process for recruiting. Both immediate corrections and long-term recommendations are useful for sister services. PMID:9465569

    In this paper, we like to discuss observational and modeling strategy for understanding the air pollution effects on climate and public health in Asia. Satellite remote sensing of aerosol signature and radiative forcing is important but still has a large uncertainties because of various bias in passive imaging and active sensing by, for example, MODIS and CALIPSO. We summarize the uncertainty in the total aerosol direct effect from satellite observation and modeling as about 4 Wm-2 (Schutgens et al., Remote Sens. 2012; Oikawa et al., JGR 2013). This situation suggests that important activities should be in development of good surface and satellite measurements of aerosols as well as establishing aerosol assimilation system. In this direction, we have developed a flexible aerosol assimilation system based on the NICAM non-hydrostatic finite grid atmospheric model (Tomita and Satoh, Fluid Dyn. Res. 2004) with flexible grid system and good mass conservation coupled with the SPRINTARS aerosol model (Takemura et al., JGR 2000). We like to present our assessment of aerosol fields in Asian continental scale as well as a mega-city basin scale around Tokyo. Health care effects are also evaluated to show that the mortality rate by air pollution will increase even with RCP4.5 scenario in which PM2.5 decreases in future (2030 horizon) in Tokyo mega-city region, because of the shifted age composition of population. We will extend our discussion to a strategy to utilize the next generation satellite systems, such as EarthCARE, Himawari-8 and 9, GCOM/C, and GOSAT-2 which are equipped with advanced functions of aerosol remote sensing.

    Clean air is one of the basic requirements of human health and well-being. However, almost nine out of 10 individuals living in urban areas are affected by air pollution. Populations living in Africa, South-East Asia, and in low- and middle-income countries across all regions are the most exposed. Exposure to outdoor air pollution ranks as the ninth leading risk factor for mortality, killing 3.2 million people each year, especially young children, the elderly, persons with lung or cardiovascular disease, those who work or exercise outdoors and low-income populations. In October 2013, the International Agency for Research on Cancer (IARC) classified outdoor air pollution as carcinogenic to humans, calling air pollution 'a major environmental health problem'. Human rights and environmental norms are powerful tools to combat air pollution and its impact on health. The dependence of human rights on environmental quality has been recognised in international texts and by human rights treaty bodies. The growing awareness of the environment has already yielded considerable legislative and regulatory output. However, the implementation of standards remains a pervasive problem. In the fight against violations of norms, citizens have a crucial role to play. We discuss the relevance of a yet to be proclaimed standalone right to a healthy environment. PMID:26162353

  14. The Economic Value of Air Quality Forecasting

    Science.gov (United States)

    Anderson-Sumo, Tasha

    Both long-term and daily air quality forecasts provide an essential component to human health and impact costs. According the American Lung Association, the estimated current annual cost of air pollution related illness in the United States, adjusted for inflation (3% per year), is approximately $152 billion. Many of the risks such as hospital visits and morality are associated with poor air quality days (where the Air Quality Index is greater than 100). Groups such as sensitive groups become more susceptible to the resulting conditions and more accurate forecasts would help to take more appropriate precautions. This research focuses on evaluating the utility of air quality forecasting in terms of its potential impacts by building on air quality forecasting and economical metrics. Our analysis includes data collected during the summertime ozone seasons between 2010 and 2012 from air quality models for the Washington, DC/Baltimore, MD region. The metrics that are relevant to our analysis include: (1) The number of times that a high ozone or particulate matter (PM) episode is correctly forecasted, (2) the number of times that high ozone or PM episode is forecasted when it does not occur and (3) the number of times when the air quality forecast predicts a cleaner air episode when the air was observed to have high ozone or PM. Our collection of data included available air quality model forecasts of ozone and particulate matter data from the U.S. Environmental Protection Agency (EPA)'s AIRNOW as well as observational data of ozone and particulate matter from Clean Air Partners. We evaluated the performance of the air quality forecasts with that of the observational data and found that the forecast models perform well for the Baltimore/Washington region and the time interval observed. We estimate the potential amount for the Baltimore/Washington region accrues to a savings of up to 5,905 lives and 5.9 billion dollars per year. This total assumes perfect compliance with

    Full Text Available Reducing the effects of climate change and air pollution is at present a global priority. Development and implementation of effective policies in order to achieve these  reductions is a challenge that requires a good understanding of the underlying phenomena  of climate change and air pollution. This paper aims to highlight the seasonal variation of PM10 concentration in Pitesti city depending on major meteorological factors (temperature, intensity of solar radiation, and relative humidity. The applied methodology consists in statistical processing, using specialized software, of a database containing historical records of concentration values of this pollutant and of meteorological parameters recorded concurrently. The results of processing a series of approximately 30000 values recorded from 2008 to 2011 indicate the fact that in every season (winter,spring, summer, and autumn the concentration of PM10 varies according to a sixth degree polynomial function, whose variable is one of the considered meteorological factors. The mathematical relationship that best approximates the variation of average PM10 concentration in relation with the three meteorological factors is by the form of a multiple linear regression equation.Keywords: air pollution and human health, particulate matters related with meteorological factors, statistical analysis

    In 1991 the Government of the Czech republic in Ruling No 369 approved a draft of a system for monitoring the health of the population in relation to the environment on the basis of a need to obtain purposefully targeted information for an appropriate policy for the protection of health and the environment. The aim of monitoring does not and cannot consist of determining the cause and effect relationship between the health status and pollutants. The system of monitoring is an open and comprehensive system of the continual collection, processing and evaluation of data concerned with the load on the organism and damage to human health in relation to environmental pollution. Air pollution and health are one of the six subsystems realised in the whole system (beside drinking water, noise, food, biomarkers, and demographic and health statistics). The aim of the monitoring is to obtain a data base that shall serve three main purposes: (1) Description of the status of health of the population and characteristics of the ambient air, (2) Evaluation of the trend of each index, (3) Assessment and evaluation of the risk to health of the parameters under study. Thirty cities and towns were selected in the Czech Republic for the realisation of the monitoring system. (author)

  19. Aerosol Health Impact Source Attribution Studies with the CMAQ Adjoint Air Quality Model

    Turner, M. D.

    Fine particulate matter (PM2.5) is an air pollutant consisting of a mixture of solid and liquid particles suspended in the atmosphere. Knowledge of the sources and distributions of PM2.5 is important for many reasons, two of which are that PM2.5 has an adverse effect on human health and also an effect on climate change. Recent studies have suggested that health benefits resulting from a unit decrease in black carbon (BC) are four to nine times larger than benefits resulting from an equivalent change in PM2.5 mass. The goal of this thesis is to quantify the role of emissions from different sectors and different locations in governing the total health impacts, risk, and maximum individual risk of exposure to BC both nationally and regionally in the US. We develop and use the CMAQ adjoint model to quantify the role of emissions from all modeled sectors, times, and locations on premature deaths attributed to exposure to BC. From a national analysis, we find that damages resulting from anthropogenic emissions of BC are strongly correlated with population and premature death. However, we find little correlation between damages and emission magnitude, suggesting that controls on the largest emissions may not be the most efficient means of reducing damages resulting from BC emissions. Rather, the best proxy for locations with damaging BC emissions is locations where premature deaths occur. Onroad diesel and nonroad vehicle emissions are the largest contributors to premature deaths attributed to exposure to BC, while onroad gasoline emissions cause the highest deaths per amount emitted. Additionally, emissions in fall and winter contribute to more premature deaths (and more per amount emitted) than emissions in spring and summer. From a regional analysis, we find that emissions from outside each of six urban areas account for 7% to 27% of the premature deaths attributed to exposure to BC within the region.

  20. Indoor metallic pollution related to mining activity in the Bolivian Altiplano

    International Nuclear Information System (INIS)

    The environmental pollution associated with mining and metallurgical activities reaches its greatest extent in several Andean cities and villages. Many locations in this area have accumulated through centuries a large amount of mining wastes, often disregarding the magnitude of this situation. However, in these naturally mineralized regions, there is little information available stating the exact role of mining and metallurgical industries in urban pollution. In this study, we demonstrated that the various metallic elements present in indoor dust (As, Cd, Cu, Pb, Sb, Sn, Zn) had a common origin and this contamination was increased by the proximity to the mines. Lead dust concentration was found at concerning levels for public health. In addition, wrong behaviors such as carrying mining workwear home contributed to this indoor dust pollution. Consequently, the constant exposure of the population could represent a potential health hazard for vulnerable groups, especially children. - Highlights: → We measured polymetallic pollution in household indoor dust from a mining town. → Toxic elements (Pb, As, Cd, Sb) in dust are correlated, suggesting a common origin. → The most polluted houses are within a 1 km radius around the mining center. → Carrying mining workwear home increases indoor pollution. → Lead concentrations in dust represent a serious concern for Public Health (600 μg/g). - In a typical Andean mining city, the urban indoor pollution with toxic metallic elements is directly related to the closeness of the mining activities.

    At the present time, ambient air pollution is a serious public health problem in China. Based on the concentration-response relationship provided by international and domestic epidemiologic studies, the authors estimated the mortality and morbidity induced by the ambient air pollution of 2000. To address the mechanism of the health impact on the national economy, the authors applied a computable general equilibrium (CGE) model, named AIM/Material China, containing 39 production sectors and 32 commodities. AIM/Material analyzes changes of the gross domestic product (GDP), final demand, and production activity originating from health damages. If ambient air quality met Grade II of China's air quality standard in 2000, then the avoidable GDP loss would be 0.38%o of the national total, of which 95% was led by labor loss. Comparatively, medical expenditure had less impact on national economy, which is explained from the aspect of the final demand by commodities and the production activities by sectors. The authors conclude that the CGE model is a suitable tool for assessing health impacts from a point of view of national economy through the discussion about its applicability. PMID:16121834

    The “Industrial Heartland” of Alberta is Canada's largest hydrocarbon processing center, with more than 40 major chemical, petrochemical, and oil and gas facilities. Emissions from these industries affect local air quality and human health. This paper characterizes ambient levels of 77 volatile organic compounds (VOCs) in the region using high-precision measurements collected in summer 2010. Remarkably strong enhancements of 43 VOCs were detected, and concentrations in the industrial plumes were often similar to or even higher than levels measured in some of the world's largest cities and industrial regions. For example maximum levels of propene and i-pentane exceeded 100 ppbv, and 1,3-butadiene, a known carcinogen, reached 27 ppbv. Major VOC sources included propene fractionation, diluent separation and bitumen processing. Emissions of the measured VOCs increased the hydroxyl radical reactivity (kOH), a measure of the potential to form downwind ozone, from 3.4 s-1 in background air to 62 s-1 in the most concentrated plumes. The plume value was comparable to polluted megacity values, and acetaldehyde, propene and 1,3-butadiene contributed over half of the plume kOH. Based on a 13-year record (1994-2006) at the county level, the incidence of male hematopoietic cancers (leukemia and non-Hodgkin lymphoma) was higher in communities closest to the Industrial Heartland compared to neighboring counties. While a causal association between these cancers and exposure to industrial emissions cannot be confirmed, this pattern and the elevated VOC levels warrant actions to reduce emissions of known carcinogens, including benzene and 1,3-butadiene.

Despite growing evidence, several controversies and disagreements exist among the studies that have analyzed the effects of prenatal pollutant exposure. This review article aims to analyze primary scientific evidence of the effects of air pollution during pregnancy and the impact of these effects on the fetus, infant health, and in particular, the respiratory system. We performed a review of articles from the PubMed and Web of Science databases that were published in English within the past 5 years, particularly those related to birth cohorts that began in pregnancy with follow-up until the first years of life. The largest reported effects are associated with prenatal exposure to particulate matter, nitrogen dioxide, and tobacco smoke. The primary effects affect birth weight and other parameters of fetal biometry. There is strong evidence regarding the impact of pollutants on morbidity secondary to respiratory problems. Growing evidence links maternal smoking to childhood asthma and wheezing. The role of passive maternal smoking is less clear. Great heterogeneity exists among studies. There is a need for additional studies on birth cohorts to monitor the relationship between the exposure of pregnant women to pollutants and their children’s progress during the first years of life.

    Full Text Available A consensus has been emerging among public health experts in developing countries that air pollution, even at current ambient levels, aggravates respiratory and cardiovascular diseases and leads to premature mortality. Recent studies have also presented well-founded theories concerning the biological mechanisms involved and the groups of people that are probably more susceptible to health effects caused or exacerbated by inhalation of ambient particulate matter (PM.. On the basis of prognostic studies carried out in Center for Environment, JNT University, Hyderabad “it has been estimated that in Hyderabad some 1,700 to 3,000 people per year die prematurely as a result of inhaling PM”. These figures reflect only the effects of acute exposure to air pollution. If the long-term effects of chronic exposure are taken into account, 10,000–15,000 people a year could die prematurely in Hyderabad. This estimate of the chronic effects is based on other studies, which are not completely comparable with the Hyderabad situation. While the study designs and analyses in these other studies may indeed be different or irrelevant to Hyderabad, the fact they were carried out in other countries is irrelevant. Taking into account these considerations, a model for total health risk assessment for the city of Hyderabad, and its state of Andhra Pradesh in India has been developed using a multi-objective air pollution monitoring network and online and real time air pollution monitoring stations. For the model studies a number of potential monitoring sites were screened for general and site-specific criteria in a geographic information system (GIS environment that may, on a local basis, affect the representativeness of the data collected. Local features that may affect either the chemical or meteorological parameters are evaluated to assure a minimum of interference. Finally, for monitoring air pollution, an online and real

    Urban traffic influences air quality in cities considerably. This is particularly true for the medieval parts of the big European cities, which have not been designed for today s heavy traffic. A problem closely associated with city traffic, is the lack of parking lots, particularly for residents. In Vienna, the parking problem is tackled by the building of underground car parks. In the next years more than 50 large garages (>100 sites) are being planned. The main goal is the clearing of the beautiful old places and streets of Vienna from the bulk of parking vehicles and supplying the citizens with parking spaces in the neighbourhood. According to a recent decision of the City Council of Vienna the construction of `large garages` (>100 parking spaces) requires an official approval by various local authorities. Among them are those responsible for town design and architecture, for fire precaution and fire fighting, for city traffic, for planning and building and for environmental health. In this context the Institute of Environmental Medicine of the City Council of Vienna faced the task of establishing criteria for a health risk assessment linked with `large garages`. Health-risks may be caused by air pollution and noise. This presentation deals with the air pollution problem. Air pollution problems may occur due to traffic in and out of the garage, by insufficient ventilation systems and by construction failures. In the garage programme the health officers have to bring evidence that residents of the houses with underground car parks and residents in the close neighbourhood are not exposed to any health risk due to air pollution

Growing evidence links maternal smoking to childhood asthma and wheezing. The role of passive maternal smoking is less clear. Great heterogeneity exists among studies. There is a need for additional studies on birth cohorts to monitor the relationship between the exposure of pregnant women to pollutants and their children's progress during the first years of life.

    A survey and critical review were undertaken of existing published literature and reports on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, including California schools. Over 450 relevant publications were obtained and reviewed, including papers published in the archival peer-reviewed scientific literature, proceedings of scientific meetings, government reports, 77 NIOSH Health Hazard Evaluation Reports (HHER) and 70 reports on investigations of problem schools in California. Most of the reviewed literature was for complaint or problem schools. The types of health symptoms reported in schools were very similar to those defined as sick building syndrome (SBS) symptoms, although this may be due, at least in part, to the type of health symptom questionnaires used. Some of the symptoms, e.g., wheezing, are indicative of asthma. In the studies in which complaint and noncomplaint buildings or areas were compared, complaint buildings generally had higher rates of health symptoms.

  12. Pollution level, phase distribution and health risk of polycyclic aromatic hydrocarbons in indoor air at public places of Hangzhou, China

    International Nuclear Information System (INIS)

    PAHs pollution survey in air of public places was conducted in Hangzhou, China. The most serious PAHs pollution was observed in indoor air of shopping centers and the slightest was in train stations. The molecular weight of chrysene (MW 228) appeared to be the dividing line for the PAHs with a larger or smaller distribution in the vapor or particulate phase. Concentrations of 15 PAHs on PM2.5 accounted for 71.3% of total particulate PAHs, and followed by PM2.5-10 fraction (17.6%) and >PM10 fraction (11.1%). In shopping centers and supermarkets, emission of 2-4 rings PAHs occurred from indoor sources, whereas 5-6 rings PAHs predominantly originated from transport of outdoor air. In temples, PAHs in indoor air mainly originated from incense burning. Health risks associated with the inhalation of PAHs were assessed, and naphthalene made the greatest contribution (62.4%) to the total health risks. - Concentrations of PAHs in the air of selected public places in Hangzhou correspond to 10-3 life-time lung cancer risk

    Full Text Available Within ACCENT, a European Network of Excellence, eighteen atmospheric models from the U.S., Europe, and Japan calculated present (2000 and future (2030 concentrations of ozone at the Earth's surface with hourly temporal resolution. Comparison of model results with surface ozone measurements in 14 world regions indicates that levels and seasonality of surface ozone in North America and Europe are characterized well by global models, with annual average biases typically within 5–10 nmol/mol. However, comparison with rather sparse observations over some regions suggest that most models overestimate annual ozone by 15–20 nmol/mol in some locations. Two scenarios from the International Institute for Applied Systems Analysis (IIASA and one from the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (IPCC SRES have been implemented in the models. This study focuses on changes in near-surface ozone and their effects on human health and vegetation. Different indices and air quality standards are used to characterise air quality. We show that often the calculated changes in the different indices are closely inter-related. Indices using lower thresholds are more consistent between the models, and are recommended for global model analysis. Our analysis indicates that currently about two-thirds of the regions considered do not meet health air quality standards, whereas only 2–4 regions remain below the threshold. Calculated air quality exceedances show moderate deterioration by 2030 if current emissions legislation is followed and slight improvements if current emissions reduction technology is used optimally. For the "business as usual" scenario severe air quality problems are predicted. We show that model simulations of air quality indices are particularly sensitive to how well ozone is represented, and improved accuracy is needed for future projections. Additional measurements are needed to allow a more quantitative

  18. Measurement and estimated health risks of volatile organic compounds and polychlorinated biphenyls in air at the Hanford Site

    International Nuclear Information System (INIS)

    A variety of radioactive and nonradioactive chemicals have been released in effluent streams and discharged to waste disposal facilities during the nuclear materials production period at the Hanford Site. Extensive environmental surveillance for radioactive materials has occurred at Hanford; however, only limited information is available on the types and concentrations of organic pollutants potentially present. This report describes work performed to provide the Hanford Site Surface Environmental Surveillance Project with representative air concentration data for volatile organic compounds and polychlorinated biphenyls (PCBs). US Environmental Protection Agency (USEPA) volatile organic compound sampling methods evaluated for Hanford Site use were carbon-based adsorbent traps (TO-2) and Summa air canisters (TO-14). Polychlorinated biphenyls were sampled using USEPA method (TO-4), which uses glass fiber filters and polyurethane foam adsorbent beds to collect the PCBS. This report also presents results for environmental surveillance samples collected for volatile organic compound and PCB analyses from 1990 to 1993. All measured air concentrations of volatile organic compounds and PCBs were well below applicable maximum allowable concentration standards for air contaminants. Because of the lack of ambient air concentration standards, a conservative estimate is provided of the potential human health impacts from exposure to the ambient air concentrations measured on the Hanford Site

  1. The assessment of health damage caused by air pollution and its implication for policy making in Taiyuan, Shanxi, China

    International Nuclear Information System (INIS)

    We establish the link between energy use, air pollution, and public health impacts in Taiyuan for 2000, and for 2010 and 2015 under alternative scenarios. We find that in year 2000 more than 2200 excess deaths may have been caused by particulate matter (PM) pollution. Using alternative methods for monetization of health impacts the total health damage amounts to 0.8-1.7 billion Yuan, which is 2.4-4.9% of the city's GDP in 2000. Compared to the business-as-usual scenario, scenarios assuming extensive fuel switch in low-and-medium-stack pollution sources and extension of the district heating system could prevent 200-1100 PM10-related premature deaths in 2010 and substantially reduce population morbidity. The actual PM pollution in 2007 was lower than modeled in these two scenarios. We also find that if air quality in urban Taiyuan were to reach the Chinese National Grade II Standard in 2015, the number of premature deaths would still be around 1330 and the economic cost about 1-2% of the city's GDP in 2015. Our results imply that there are large health benefits to be gained by setting stricter standards for the future in China, and that targeting low-and-medium-stack source effectively reduces health damage.

    To assess the status of, and factors associated with, residents' knowledge, attitudes, and practices (KAP) related to air pollution and respiratory health of children in Shanghai, we conducted a cross-sectional survey. Demographic factors associated with residents' knowledge were identified by multiple logistic regressions. The questionnaires were completed by 972 participants, half from the Shanghai Children Hospital and the other half from the Jiading communities. Half of the participants' scores of knowledge and attitudes were equal or greater than 8.0 on a 9-point scale, over 75% of respondents' practice scores were equal to or less than 4.0. Our studies demonstrated a significant difference of average knowledge scores between the two groups (t = 1.27, p air quality and their perception of the government's efforts to alleviate it. The hospital and community groups also showed significant differences in practices geared towards protecting their children's health. Nearly 90% of the respondents agreed that improving air quality is the responsibility of every citizen, and the joint action of governments and all citizens should be utilized for enhanced control. In addition, more resources should be allocated towards providing citizens with appropriate practices to help lessen the effects of poor air quality. PMID:25664694

    Choo, Chua Poh; Jalaludin, Juliana

    2015-01-01

    The indoor environment is a major source of human exposure to pollutants. Some pollutants can have concentrations that are several times higher indoors than outdoors. Prolonged exposure may lead to adverse biologic effects, even at low concentrations. Several studies done in Malaysia had underlined the role of indoor air pollution in affecting respiratory health, especially for school-aged children. A critical review was conducted on the quantitative literature linking indoor air pollution with respiratory illnesses among school-aged children. This paper reviews evidence of the association between indoor air quality (IAQ) and its implications on respiratory health among Malaysian school-aged children. This review summarizes six relevant studies conducted in Malaysia for the past 10 years. Previous epidemiologic studies relevant to indoor air pollutants and their implications on school-aged children's respiratory health were obtained from electronic database and included as a reference in this review. The existing reviewed data emphasize the impact of IAQ parameters, namely, indoor temperature, ventilation rates, indoor concentration of carbon dioxide (CO2), carbon monoxide (CO), particulate matters (PM), volatile organic compounds (VOCs), nitrogen dioxide (NO2) and airborne microbes, on children's respiratory health. The study found that most of the Malaysian school-aged children are exposed to the inadequate environment during their times spent either in their houses or in their classrooms, which is not in compliance with the established standards. Children living in households or studying in schools in urban areas are more likely to suffer from respiratory illnesses compared with children living in homes or studying in schools in rural areas.

    2016-07-15

    The volume and type of traffic and exposure to air pollution have been found to be associated with respiratory health, but few studies have considered the interaction with socioeconomic status at the household level. We investigated the relationships of respiratory health related to traffic type, traffic volume, and air pollution, stratifying by socioeconomic status, based on household income and education, in 3591 schoolchildren in Windsor, Canada. Interquartile range changes in traffic exposure and pollutant levels were linked to respiratory symptoms and objective measures of lung function using generalised linear models for three levels of income and education. In 95% of the relationships among all cases, the odds ratios for reported respiratory symptoms (a decrease in measured lung function), based on an interquartile range change in traffic exposure or pollutant, were greater in the lower income/education groups than the higher, although the odds ratios were in most cases not significant. However, in up to 62% of the cases, the differences between high and low socioeconomic groups were statistically significant, thus indicating socioeconomic status (SES) as a significant effect modifier. Our findings indicate that children from lower socioeconomic households have a higher risk of specific respiratory health problems (chest congestion, wheezing) due to traffic volume and air pollution exposure.

    2016-01-01

    The U.S. health care sector is highly interconnected with industrial activities that emit much of the nation’s pollution to air, water, and soils. We estimate emissions directly and indirectly attributable to the health care sector, and potential harmful effects on public health. Negative environmental and public health outcomes were estimated through economic input-output life cycle assessment (EIOLCA) modeling using National Health Expenditures (NHE) for the decade 2003–2013 and compared to national totals. In 2013, the health care sector was also responsible for significant fractions of national air pollution emissions and impacts, including acid rain (12%), greenhouse gas emissions (10%), smog formation (10%) criteria air pollutants (9%), stratospheric ozone depletion (1%), and carcinogenic and non-carcinogenic air toxics (1–2%). The largest contributors to impacts are discussed from both the supply side (EIOLCA economic sectors) and demand side (NHE categories), as are trends over the study period. Health damages from these pollutants are estimated at 470,000 DALYs lost from pollution-related disease, or 405,000 DALYs when adjusted for recent shifts in power generation sector emissions. These indirect health burdens are commensurate with the 44,000–98,000 people who die in hospitals each year in the U.S. as a result of preventable medical errors, but are currently not attributed to our health system. Concerted efforts to improve environmental performance of health care could reduce expenditures directly through waste reduction and energy savings, and indirectly through reducing pollution burden on public health, and ought to be included in efforts to improve health care quality and safety.

  14. Associations between Parents' Perceived Air Quality in Homes and Health among Children in Nanjing, China.

    Directory of Open Access Journals (Sweden)

    Hua Qian

    Full Text Available The increasing prevalence of respiratory diseases in Chinese children has focused attention on indoor environmental quality. We investigated associations between perceived air quality in domestic environments and children's allergic diseases with a questionnaire survey study. A total of 4017 children aged 1-8 years old from 23 kindergartens in urban, suburban and industrial areas in Nanjing were randomly recruited for this study. Parents' perceived odors, including stuffy odor, unpleasant odor, pungent odor, moldy odor, humid air and dry air were found to be associated with asthma, wheeze, dry cough and rhinitis (P < 0.05. Both perceived dry and humid air were found to be positively associated with dampness indices, and we present evidence that the sensation of dryness may not be due to the actual indoor relative humidity, but rather to indoor air irritants. Parents' perception of odors and relative humidity may be indicators of environment pollutants, which are likely the real factors associated with children's allergic diseases.

    A cohort study in West Germany investigates the effects of air pollutants in patients with chronic obstructive airway diseases, such as chronic bronchitis, asthma, and emphysema. Within the state of North-Rhine Westfalia, some parts of the Ruhr district are more heavily contaminated with air pollutants than others. Patients between the age of 50 and 70 y from ares with different levels of air pollutants are included in the study. The cohort will be followed for 3 y, from September through April, when the level of air pollutants is the highest in West Germany. After a complete physical examination each participant will be seen by a physician every two months during the observation period. The most important component of the study is the daily diaries. Each day, three peak-flow measurements are taken and recorded. Other parameters inquired about daily include the use of medication, smoking habits, time spent outside, and the participants' well-being. These parameters will be compared with daily measurements of air pollutants to see whether already small increases will result in acute health problems of this group. A pilot study, which started in September 1987 and ended in April 1988, showed a good compliance. Of 108 participants, only 8 withdrew from the study during that time. The second phase of the study lasted from September 1988 through April 1989, and the last phase began in September 1989 and finished in April 1990.

    The Pearl River Delta region (PRD) is the economic growth engine of China and also one of the most urbanized regions in the world. As a two-sided sword, rapid economic development causes air pollution and poses adverse health effects to the citizens in this area. This work estimated the negative health effects in the PRD caused by the four major ambient pollutants (SO2, NO2, O3 and PM10) from 2010 to 2013 by using a log linear exposure-response function and the WRF-CMAQ modeling system. Economic loss due to mortality and morbidity was evaluated by the value of statistical life (VSL) and cost of illness (COI) methods. The results show that the overall possible short-term all-cause mortality due to NO2, O3 and PM10 reached the highest in 2013 with the values being 13,217-22,800. The highest total economic loss, which ranged from 14,768 to 25,305million USD, occurred in 2013 and was equivalent to 1.4%-2.3% of the local gross domestic product. The monthly profile of cases of negative health effects varied by city and the types of ambient pollutants. The ratio of mortality attributed to air pollutants to total population was higher in urban areas than in rural areas. People living in the countryside should consider the possible adverse health effects of urban areas before they plan a move to the city. The results show that the health burden caused by the ambient pollutants over this region is serious and suggest that tighter control policies should be implemented in the future to reduce the level of air pollution.

    The InVS published its first results on the Nine-City Air and Health Surveillance Programme (PSAS-9) in March 1999. This phase I pointed out that it was possible for various specialists in the field of air pollution and health to gather around a common set of problems. They also found a link between the daily variations of all the urban air pollution indicators and the total, cardio-vascular and respiratory mortality which, based on French data, contributed to strengthen scientific knowledge in this field. Today's report presents the results of phase Il of the PSAS-9 programme which essentially aimed at assessing the short-term exposure-risk relationships between pollution indicators and hospital admission indicators. This second phase also allowed to confirm the results of phase I on the short-term effect of air pollution on mortality thanks to longer periods of study. Exploratory analysis using new indicators and sensitivity analysis on the pertinence of results were also conducted. Finally, methodological tools were developed in order to optimise data collection and statistical modelization. All these results enabled the quantification of the short-term health impact of air pollution on the PSAS-9 cities. PSAS-9 is now an ongoing epidemiological surveillance programme on the effects of urban air pollution on health, providing information tools to decision-makers and the general population. (author)

    Full Text Available Abstract Background Indoor air pollution (IAP from solid fuels is a serious health problem in low-income countries that can be alleviated using improved stoves. Although women are the principal users, few studies have investigated the self-assessed impact of the stoves on their health and lives. Methods This study was conducted in rural highland Guatemala, involving 89 intervention and 80 control Mayan Indian young women (mean 27.8 years, SD 7.2. Outcomes were assessed after approximately 18 months use of the new stove. Our objectives were to compare self-rated health and change in health among women participating in a randomised control trial comparing a chimney stove with an open fire, to describe impacts on women's daily lives and their perceptions of how reduced kitchen smoke affects their own and their children's health. Results On intention-to-treat analysis, 52.8% of intervention women reported improvement in health, compared to 23.8% of control women (p Conclusion Women's perception of their health was improved, but although smoke reduction was valued, this was linked mainly with alleviation of non-respiratory symptoms like eye discomfort and headache. More focus on such symptoms may help in promoting demand for improved stoves and cleaner fuels, but education about more severe consequences of IAP exposure is also required.

  19. Maquiladoras, Air Pollution, and Human Health in Ciudad Juarez and El Paso

    Ciudad Juárez, Chihuahua, is home to the U.S.–Mexico border’s largest maquiladora labor force, and also its worst air pollution. We marshal two types of evidence to examine the link between maquiladoras and air pollution in Ciudad Juárez, and in its sister city, El Paso, Texas. First, we use a publicly available sector-level emissions inventory for Ciudad Juárez to determine the importance of all industrial facilities (including maquiladoras) as a source of air pollution. Second, we use origi...

    Full Text Available Background. Epidemiological studies point out that air pollution in the cities was a major risk for health of the exposed population. In particular, the effects of air pollutants were adverse to the respiratory tract. In Niš and Niška Banja, the concentrations of pollutants were mainly below the threshold values. However, according to the literature, even these concentrations could exert negative effects, especially the health of the most sensitive group, such as the preschool children. The aim of our study was to evaluate the effects of the current levels of air pollutants in the city of Niš on respiratory symptoms and diseases. Methods. A pilot, cohort, retrospective study included 1 385 children of 1-5 years of age from the zones with statistically significant concentrations of air pollutants, in the period after the birth of the children. The prevalence of respiratory symptoms and diseases was determined on the basis of a modified WHO standard questionnaire completed by the parents. Results. It was revealed that in the more polluted of the studied zones, the prevalence of some respiratory symptoms (cough with cold and phlegm, and the lower respiratory tract diseases was significantly higher. Conclusion. The results of our study showed that the current concentrations of air pollutants in Niš and Niška Banja could represent the important etiological factor for the development of respiratory symptoms and diseases. Our study showed that in the children of up to 5 years of age, the frequency of respiratory symptoms and diseases was significantly higher in more polluted than in less polluted environments.

    From 2005 to 2009 there was a 40% decrease in the number of days on which the European daily limit value of PM10 was exceeded at traffic locations in European cities. Yet, in many of these cities, air quality is still not in compliance with the European Air Quality Directive and additional traffic measures are planned. Our study shows that elemental carbon (EC) is a more appropriate indicator than PM2.5 and PM10 for evaluating the impact of traffic measures on air quality and health. The modelled improvement in EC concentration was translated in life years gained as a result of a traffic measure. This was investigated for a speed management zone on a motorway in the city of Rotterdam. Eighty-five per cent of those living within 400 m of the motorway gained 0-1 months of life expectancy and another 15% gained 1-3 months, depending on their distance from the motorway. In addition, EC was used to evaluate a low emission zone in Amsterdam, specifically for those living along inner-urban roads with intense traffic levels. The zone only restricts heavy duty vehicles with Euro emission class 0 to 2, Euro 3 older than eight years or more recent Euro 3 without diesel particulate filter. The results indicate a population-weighted, average gain of 0.2 months in life expectancy as compared with a maximum potential gain of 2.9 months. It is concluded that on motorways speed management is an effective measure, while a low emission zone as implemented in our case study, is less effective to reduce health effects of road traffic emissions. For inner-urban roads reduction of traffic volume seems the most effective traffic measure for improving air quality and health.

    Objective Nearly all China’s rural residents and a shrinking fraction of urban residents use solid fuels (biomass and coal) for household cooking and/or heating. Consequently, global meta-analyses of epidemiologic studies indicate that indoor air pollution from solid fuel use in China is responsible for approximately 420,000 premature deaths annually, more than the approximately 300,000 attributed to urban outdoor air pollution in the country. Our objective in this review was to help elucidat...

    Air pollution worldwide has been associated with cardiovascular and respiratory morbidity and mortality, particularly in urban settings with elevated concentrations of primary pollutants. Air pollution is a very complex mixture of primary and secondary gases and particles, and its potential to cause harm can depend on multiple factors—including physical and chemical characteristics of pollutants, which varies with fine-scale location (e.g., by proximity to local emission sources)—as well as l...

    On normal days, the temperature decreases with altitude, allowing air pollutants to rise and disperse. During inversion episodes, a warmer air layer at higher altitude traps pollutants close to the ground. We show how readily available NASA satellite data on vertical temperature profiles can be used to measure inversion episodes on a global scale with high spatial and temporal resolution. Then, we link inversion episode data to ground level pollution monitors and to daily in- and outpatient r...

    2014-04-01

    Full Text Available Indoor air pollution caused by the indoor burning of solid biomass fuels has been associated with Acute Respiratory Infections such as pneumonia amongst children of less than five years of age. Behavioural change interventions have been identified as a potential strategy to reduce child indoor air pollution exposure, yet very little is known about the impact of behavioural change interventions to reduce indoor air pollution. Even less is known about how behaviour change theory has been incorporated into indoor air pollution behaviour change interventions. A review of published studies spanning 1983–2013 suggests that behavioural change strategies have the potential to reduce indoor air pollution exposure by 20%–98% in laboratory settings and 31%–94% in field settings. However, the evidence is: (1 based on studies that are methodologically weak; and (2 have little or no underlying theory. The paper concludes with a call for more rigorous studies to evaluate the role of behavioural change strategies (with or without improved technologies to reduce indoor air pollution exposure in developing countries as well as interventions that draw more strongly on existing behavioural change theory and practice.

    Building Health Sciences, Inc. (BHS), investigated environmental conditions by many modalities in 71 discreet areas of 12 buildings in a government building complex that had experienced persistent occupant complaints despite correction of deficiencies following a prior survey. An online health survey was completed by 7,637 building occupants (49% response rate), a subset of whom voluntarily wore personal sampling apparatus and underwent medical evaluation. Building environmental measures were within current standards and guidelines, with few outliers. Four environmental factors were consistently associated with group-level building-related health complaints: physical comfort/discomfort, odor, job stress, and glare. Several other factors were frequently commented on by participants, including cleanliness, renovation and construction activities, and noise. Low relative humidity was significantly associated with lower respiratory and "sick building syndrome"-type symptoms. No other environmental conditions (including formaldehyde, PM10 [particulate matter with an aerodynamic diameter conditions, or together, were hierarchically associated with the following: increased absence, increased presenteeism (presence at work but at reduced capacity), and increase in reported symptom-days, including symptoms not related to respiratory disease. We found that in buildings without unusual hazards and with environmental and air quality indicators within the range of acceptable indoor air quality standards, there is an identifiable population of occupants with a high prevalence of asthma and allergic disease who disproportionately report discomfort and lost productivity due to symptoms and that in "normal" buildings these outcome indicators are more closely associated with host factors than with environmental conditions. We concluded from the experience of this study that building-related health complaints should be investigated at the work-area level and not at a building

    Full Text Available Gwalior is a historical and major city in the Indian state of Madhya Pradesh. It is located south of Delhi the capital city of India, and 423 kilometers north of Bhopal, the state capital. Gwalior is being called as The Heart of Incredible India. Gwalior is surrounded by industrial and commercial zones of neighboring districts (Malanpur – Bhind, Banmor – Morena on all three main directions. Rapid increase in urbanization with vehicle congestion has increased enormously on the roads of Gwalior city. As a result of this, gaseous pollutants (SOx, NOx and Respirable and suspended particulate matter pollutants are continuously increasing in the ambient air of Gwalior city. Levels of SO2 were monitored at 4 locations of Gwalior city by using high volume air sampler (Envirotech APM 415 and 411. The average ambient air concentration of SO2 was found below the permissible limits of NAAQS of CPCB at all the sites. Comparatively somewhat higher concentration of SO2 was observed during these months. A health survey was also carried out which demonstrated that symptoms were developed such as sneezing, sore throat, shortness of breath, wheezing, chest tightness, skin irritation, nausea etc. In this study, an exposure–response assessment (aged 10 to 60 years was carried out related to health problems due to vehicular pollution between the months of November-2013 to May-2014 (winter. The main objectives of this study are to investigate the state of vehicular emission in Gwalior and to investigate the impact of vehicular emission on people.

    Full Text Available The Near-Road Exposures and Effects of Urban Air Pollutants Study (NEXUS investigated the impact of exposure to traffic-related air pollution on the respiratory health of asthmatic children in Detroit, Michigan. Since indoor mold exposure may also contribute to asthma, floor dust samples were collected in participants homes (n=112 to assess mold contamination using the Environmental Relative Moldiness Index (ERMI. The repeatability of the ERMI over time, as well as ERMI differences between rooms and dust collection methods, was evaluated for insights into the application of the ERMI metric. ERMI values for the standard settled floor dust samples had a mean ± standard deviation of 14.5±7.9, indicating high levels of mold contamination. ERMI values for samples collected from the same home 1 to 7 months apart (n=52 were consistent and without systematic bias. ERMI values for separate bedroom and living room samples were highly correlated (r=0.69, n=66. Vacuum bag dust ERMI values were lower than for floor dust but correlated (r=0.58, n=28. These results support the use of the ERMI to evaluate residential mold exposure as a confounder in air pollution health effects studies.

    We conducted a multi-country study to estimate the perceived economic values of traffic-related air pollution and noise health risks within the framework of a large European project. We used contingent valuation as a method to assess the willingness-to-pay (WTP) for both types of pollutants simultaneously. We asked respondents how much they would be willing to pay annually to avoid certain health risks from specific pollutants. Three sets of vignettes with different levels of information were provided prior to the WTP questions. These vignettes described qualitative general health risks, a quantitative single health risk related to a pollutant, and a quantitative scenario of combined health risks related to a pollutant. The mean WTP estimates to avoid road-traffic air pollution effects for the three vignettes were: €130 per person per year (pp/y) for general health risks, €80 pp/y for a half year shorter in life expectancy, and €330 pp/y to a 50% decrease in road-traffic air pollution. Their medians were €40 pp/y, €10 pp/y and €50 pp/y, respectively. The mean WTP estimates to avoid road-traffic noise effects for the three vignettes were: €90 pp/y for general health risks, €100 pp/y for a 13% increase in severe annoyance, and €320 pp/y for a combined-risk scenario related to an increase of a noise level from 50 dB to 65 dB. Their medians were €20 pp/y, €20 pp/y and €50 pp/y, respectively. Risk perceptions and attitudes as well as environmental and pollutant concerns significantly affected WTP estimates. The observed differences in crude WTP estimates between countries changed considerably when perception-related variables were included in the WTP regression models. For this reason, great care should be taken when performing benefit transfer from studies in one country to another. PMID:25146911

    Recently, China has frequently experienced large-scale, severe and persistent haze pollution due to surging urbanization and industrialization and a rapid growth in the number of motor vehicles and energy consumption. The vehicle emission due to the consumption of a large number of fossil fuels is no doubt a critical factor of the haze pollution. This work is focused on the causation mechanism of haze pollution related to the vehicle emission for Guangzhou city by employing the Fault Tree Analysis (FTA) method for the first time. With the establishment of the fault tree system of "Haze weather-Vehicle exhausts explosive emission", all of the important risk factors are discussed and identified by using this deductive FTA method. The qualitative and quantitative assessments of the fault tree system are carried out based on the structure, probability and critical importance degree analysis of the risk factors. The study may provide a new simple and effective tool/strategy for the causation mechanism analysis and risk management of haze pollution in China. PMID:26923237

    A survey of air pollution levels and the health of high school pupils and their parents was conducted in a heavily industrialized area of Kawasaki, Japan. The concentration of sulfur oxides in 1974 was about half of that in 1970 (0.029 ppM). The concentration of nitrogen oxides ranged from 0.030 to 0.040 ppM. There was a correlation between the concentrations of oxides of sulfur nitrogen. According to questionnaires, about 32 percent of the inhabitants showed concern about air pollution and photochemical smog. About 22 percent of the inhabitants complained of symptoms such as cold, rhinitis, and pharyngitis; and there was a correlation between total subjective symptoms and concentration of sulfur oxides. Near roadsides the concentration of nitrogen oxides was very high. Green plants are gradually disappearing from the heavily polluted area. Further industrialization in this area appears to be very dangerous for man and other living things.

    Recent studies suggest that stress can amplify the harm of air pollution. We examined whether experience of racism and exposure to particulate matter with an aerodynamic diameter of less than 2.5 µm and 10 µm (PM2.5 and PM10) had a synergistic influence on ethnic differences in asthma and lung function across adolescence. Analyses using multilevel models showed lower forced expiratory volume (FEV1), forced vital capacity (FVC) and lower rates of asthma among some ethnic minorities compared to Whites, but higher exposure to PM2.5, PM10 and racism. Racism appeared to amplify the relationship between asthma and air pollution for all ethnic groups, but did not explain ethnic differences in respiratory health. PMID:23933797

  16. Possible health effects of energy conservation: impairment of indoor air quality due to reduction of ventilation rate

    International Nuclear Information System (INIS)

    Efforts to reduce the energy needs to heat or cool dwellings have the potential to create new health hazards. Increases in indoor levels of radon and its progeny from the reduction in air exchange rates add a substantial radioactive burden to the general population. Other indoor pollutants reaching critical concentrations in homes with low air exchange rates are CO and NO2 from unvented combustion in gas stoves and heaters, tobacco smoke, and asbestos fibers. In addition, insulation materials and certain types of furniture may contribute the toxicant formaldehyde diffusing from foam injected walls or chipboard. Risk estimations using linear dose-response relationships show risk factors per kWh saved which are orders of magnitude greater than for a kWh produced by large power plants using coal, oil, gas, or uranium.

  17. A health-based assessment of particulate air pollution in urban areas of Beijing in 2000-2004

    International Nuclear Information System (INIS)

    Particulate air pollution is a serious problem in Beijing. The annual concentration of particulate matter with aerodynamic diameter less than 10 μm (PM10), ranging from 141 to 166 μg m-3 in 2000-2004, could be very harmful to human health. In this paper, we presented the mortality and morbidity effects of PM10 pollution based on statistical data and the epidemiological exposure-response function. The economic costs to health during the 5 years were estimated to lie between US$1670 and $3655 million annually, accounting for about 6.55% of Beijing's gross domestic product each year. The total costs were apportioned into two parts caused by: the local emissions and long-range transported pollution. The contribution from local emissions dominated the total costs, accounting on average for 3.60% of GDP. However, the contributions from transported pollution cannot be neglected, and the relative percentage to the total costs from the other regions could account for about 45%. An energy policy and effective measures should be proposed to reduce particulate matter, especially PM2.5 pollution in Beijing to protect public health. The Beijing government also needs to cooperate with the other local governments to reduce high background level of particulate air pollution

    There is an increasing body of evidence illustrating the negative health effects of air pollution including increased risk of respiratory, cardiac and other morbid conditions. During March and April 2014 there were two air pollution episodes in England that occurred in close succession. We used national real-time syndromic surveillance systems, including general practitioner (GP) consultations, emergency department attendances, telehealth calls and ambulance dispatch calls to further understand the impact of these short term acute air pollution periods on the health seeking behaviour of the general public. Each air pollution period was comparable with respect to particulate matter concentrations (PM10 and PM2.5), however, the second period was longer in duration (6 days vs 3 days) and meteorologically driven 'Sahara dust' contributed to the pollution. Health surveillance data revealed a greater impact during the second period, with GP consultations, emergency department attendances and telehealth (NHS 111) calls increasing for asthma, wheeze and difficulty breathing indicators, particularly in patients aged 15-64 years. Across regions of England there was good agreement between air quality levels and health care seeking behaviour. The results further demonstrate the acute impact of short term air pollution episodes on public health and also illustrate the potential role of mass media reporting in escalating health care seeking behaviour.

    Full Text Available To assess the status of, and factors associated with, residents’ knowledge, attitudes, and practices (KAP related to air pollution and respiratory health of children in Shanghai, we conducted a cross-sectional survey. Demographic factors associated with residents’ knowledge were identified by multiple logistic regressions. The questionnaires were completed by 972 participants, half from the Shanghai Children Hospital and the other half from the Jiading communities. Half of the participants’ scores of knowledge and attitudes were equal or greater than 8.0 on a 9-point scale, over 75% of respondents’ practice scores were equal to or less than 4.0. Our studies demonstrated a significant difference of average knowledge scores between the two groups (t = 1.27, p < 0.05. The parents’ educational level (OR = 1.89, 2.48 and average annual household income (AAHI (OR = 2.37, 2.40, 2.12 were the two strongest factors on knowledge awareness. In addition, statistical analysis revealed a significant difference between the two groups in their attitudes towards air quality and their perception of the government’s efforts to alleviate it. The hospital and community groups also showed significant differences in practices geared towards protecting their children’s health. Nearly 90% of the respondents agreed that improving air quality is the responsibility of every citizen, and the joint action of governments and all citizens should be utilized for enhanced control. In addition, more resources should be allocated towards providing citizens with appropriate practices to help lessen the effects of poor air quality.

    Risk assessment studies often ignore within-city variations of air pollutants. Our objective was to quantify the risk associated with fine particulate matter (PM2.5) exposure in 2 urban areas using fine-scale air pollution modeling and to characterize how this risk varied according to social deprivation. In Grenoble and Lyon areas (0.4 and 1.2 million inhabitants, respectively) in 2012, PM2.5 exposure was estimated on a 10×10m grid by coupling a dispersion model to population density. Outcomes were mortality, lung cancer and term low birth weight incidences. Cases attributable to air pollution were estimated overall and stratifying areas according to the European Deprivation Index (EDI), taking 10µg/m(3) yearly average as reference (counterfactual) level. Estimations were repeated assuming spatial homogeneity of air pollutants within urban area. Median PM2.5 levels were 18.1 and 19.6μg/m(3) in Grenoble and Lyon urban areas, respectively, corresponding to 114 (5.1% of total, 95% confidence interval, CI, 3.2-7.0%) and 491 non-accidental deaths (6.0% of total, 95% CI 3.7-8.3%) attributable to long-term exposure to PM2.5, respectively. Attributable term low birth weight cases represented 23.6% of total cases (9.0-37.1%) in Grenoble and 27.6% of cases (10.7-42.6%) in Lyon. In Grenoble, 6.8% of incident lung cancer cases were attributable to air pollution (95% CI 3.1-10.1%). Risk was lower by 8 to 20% when estimating exposure through background stations. Risk was highest in neighborhoods with intermediate to higher social deprivation. Risk assessment studies relying on background stations to estimate air pollution levels may underestimate the attributable risk. PMID:26852006

    The article analyzes actions for the prevention of cervical and breast cancer in public, private, and employment-based health services and in non-governmental organizations in the city of Buenos Aires. The article seeks to reflect on the reach and limitations of the approaches implemented in the three subsectors of the health care system and the community to prevent women from suffering or eventually dying as a consequence of these diseases, in the fragmented context of a health system with great heterogeneity in access and deep social inequalities in the use of preventive actions. The study utilizes a broad definition of prevention which integrates education, awareness-building and early detection of pre-carcinogenic and carcinogenic lesions, among other medical and non-medical components. The results were obtained using semi-structured interviews with subjects from public hospitals, employment-based health care services, private medical companies and non-governmental organizations with work in cancer prevention. These results show that contrary to a comprehensive approach, each institution limits its actions to only one aspect of prevention, implementing predominately isolated or disconnected actions inadequate to generate an autonomous and well-informed demand for treatment and health care among women.

This strategy changes the magnitude and distribution of air quality emissions and the total carbon dioxide (CO 2) emissions. We evaluate the social costs associated with these changes using a case study of 500 MW sodium-sulfur battery installations with 80% round-trip efficiency. The batteries displace peaking generators in New York City and charge using off-peak generation in the New York Independent System Operator (NYISO) electricity grid during the summer. We identify and map charging and displaced plant types to generators in the NYISO. We then convert the emissions into ambient concentrations with a chemical transport model, the Particulate Matter Comprehensive Air Quality Model with extensions (PMCAM x). Finally, we transform the concentrations into their equivalent human health effects and social benefits and costs. Reductions in premature mortality from fine particulate matter (PM 2.5) result in a benefit of 4.5 ¢ kWh -1 and 17 ¢ kWh -1 from displacing a natural gas and distillate fuel oil fueled peaking plant, respectively, in New York City. Ozone (O 3) concentrations increase due to decreases in nitrogen oxide (NO x) emissions, although the magnitude of the social cost is less certain. Adding the costs from charging, displacing a distillate fuel oil plant yields a net social benefit, while displacing the natural gas plant has a net social cost. With the existing base-load capacity, the upstate population experiences an increase in adverse health effects. If wind generation is charging the battery, both the upstate charging location and New York City benefit. At 20 per tonne of CO 2, the costs from CO 2 are small compared to those from air quality. We conclude that storage could be added to existing electricity grids as part of an integrated strategy from a

    Full Text Available The SRRMs (Steel Re-Rolling Mills are being releasing air pollutants in the environment. In order to evaluate their effect on the health of the workers, health and safety issues were analyzed by first measuring the concentrations of SO x (OIxides of Sulphur, NO x (Oxides of Nitrogen, CO (Carbon Monoxide and O2 (Oxygen produced in the three SRRMs located in SITE area Hyderabad. The mean concentration of SO x , NO x and CO were in the order of 0.35, 0.280, 6.333 ppm, respectively, whereas the mean concentration of O 2 was 203.53 thousand ppm. As per results, the concentration ofair pollutants, including SOx and NO x were significantly higher than to the NEQS (National Environmental Quality Standards and NAAQS (National Ambient Air Quality Standards. The concentration ofCO was lower than to the NAAQS, but higher than to the NEQs, while the concentration of O2 was slightly lower than to the standard value. The workers who were exposed to these air pollutants are being suffering from chronic diseases related to breathing and allergies. Moreover, labour staff was lifting heavy loads manually, which causes them to muscular and joint problems. In all the SRRMs under study, the electrical and mechanical equipments were used without any safety. The MSDS were not displayed on the workstations, the housekeeping was inadequate and most of the workers were performing their jobs without personal protective equipment. In addition to these, the other serious issues related to the occupational health and safety were an unhygienic supply of water, higher noise level, placement of explosive cylinders in the open atmosphere and unavailability of the first aid facilities in the Mill premises.

    This report describes the methodology and presents the summary results of the air pollutant monitoring program conducted by Lawrence Berkeley National Laboratory in support of the East Bay Children's Respiratory Health Study. The full study is examining the effects of chronic exposure to traffic-related pollutants on respiratory health among 3rd and 4th grade children attending ten neighborhood elementary schools in the San Francisco East Bay Area (Hayward, San Leandro and Oakland, CA). The demographically similar schools are located at varying distances from the I-880 and CA-92 freeways. Several schools were selected because they are located within 300 m in the predominant downwind direction (east) from either of the freeways. Measurements of multiple pollutants were made outdoors at the schools over 1-2 week intervals for 14 weeks in spring and eight weeks in fall 2001 using a custom-designed and validated package of commercially available monitoring equipment. Particulate matter was sampled over all hours (24 h per day) or during schools hours only with battery-operated programmable pumps and inlet devices for PM{sub 10} and PM{sub 2.5}. These pumps were modified to allow for up to 10 days of continuous operation. Fine particle mass and black carbon (BC) were determined from the collected filters. Nitrogen oxides (NO{sub x} and NO{sub 2}) were measured with passive samplers. Carbon monoxide (CO) was measured continuously with an electrochemical sensor. Gasoline-related volatile organic compounds (VOCs) were measured with passive samplers during three 4-week intervals in spring 2001 and two 4-week periods in early 2002. All samplers were deployed in a metal cabinet located outside at each school. Ranges of study average pollutant concentrations (all-hours) at the ten individual schools were: NO{sub x}, 33-68 ppb; NO{sub 2}, 19-31 ppb; PM{sub 10} mass, 27-32 {micro}g/m{sup 3}; PM{sub 2.5} mass, 12-15 {micro}g/m{sup 3}; and BC associated with PM{sub 2.5}, 0

    The objective of the study was to assess the actual ventilation and indoor air quality in the Finnish building stock (dwellings and day-care centers) with special reference to the existing guideline values. Furthermore, the objective was to evaluate the occurrence of symptoms and perceptions among occupants (adult residents, children, workers) in relation to ventilation system, ventilation rate and dampness. The measurements of ventilation and indoor air quality in the dwellings and day-care centers included ventilation rate, CO{sub 2} concentration, and temperature and humidity. Self- and parent-administered questionnaires were distributed to the occupants inquiring their personal characteristics, occurrence of symptoms of interest, perceived indoor air quality and details of their home and work environments. Airflows and air change rates varied remarkably both in the dwellings and day-care centers. In the majority of the dwellings and day-care centers, the Finnish guideline values of ventilation rates were not achieved. No consistent associations were observed between the magnitude of mechanical ventilation rates and the occurrence of eye, respiratory, skin and general symptoms, that is, symptoms of sick building syndrome (SBS) among the day-care workers. The results indicate that there is much room for improvement in the ventilation and indoor air quality of Finnish dwellings and day-care centers. The control of ventilation, temperature and humidity and the prevention of water damage are important issues on which to concentrate in the future. There is need to improve the quality in all phases of construction: design, installation, adjustment, operation, and maintenance

    Colombia has strict economic divisions, which may be represented by six strata assigned by the National Planning Department. These are assigned by housing conditions and are arranged such that the divisions with subpar living conditions (strata levels one through three) may receive support from those with better than acceptable living conditions (strata levels five and six). Notably, division three no longer receives aid, and division four neither contributes to this system nor receives support. About ten percent of the population is in the upper three strata, while the remaining populace experiences subpar living conditions. Bogotá, DC has poor air quality that sometimes puts sensitive populations at risk due to particulate matter (PM). The local environmental agency has developed seven strategies to reduce air pollution, predominantly by regulating fixed and mobile sources, for the promotion of public health. Preliminary mapping of results indicates there may be higher concentrations of pollutants in areas whose residents are of a lower socioeconomic status (SES). Because it's more difficult for impoverished people to miss work or afford healthcare, higher exposure could have more significance for the city's overall health burden. The aim of this project is to determine the effective impactful regulatory strategy for the benefit of public health as a result of emission reductions. This will be done by using CMAQ results and BenMAP with information for long-term relative risk estimates for PM to find premature mortality rates per source type and location, segregated by strata division. A statistical regression will define the correspondence between health impact and SES. The benefit per reduction will be given in premature mortalities avoided per ton of PM emissions reduced per source type. For each of seven proposed regulatory strategies, this project provides results in mortalities avoided per ton of emissions of PM reduced per source type. It also compares

    Background The Antwerp ring road has a traffic density of 300,000 vehicles per day and borders the city center. The ‘Ringland project’ aims to change the current ‘open air ring road’ into a ‘filtered tunneled ring road’, putting the entire urban ring road into a tunnel and thus filtering air pollution. We conducted a health impact assessment (HIA) to quantify the possible benefit of a ‘filtered tunneled ring road’, as compared to the ‘open air ring road’ scenario, on air quality and its long-...

  14. Health impacts of air pollution on morbidity and mortality among children of Ciudad Juarez, Chihuahua, Mexico : working paper

    International Nuclear Information System (INIS)

    This study evaluated the impact of air pollution on a group of children in Ciudad Juarez, Mexico where a large urban population of children live in poor conditions. In particular, the study examined the associations between ozone ambient levels and respiratory-related emergency visits to hospitals by children. The impact of PM10 on respiratory health was also examined. Upper respiratory infections and asthma were found to be associated with ozone ambient levels for all age groups. In children aged 5 or less, ozone exposure was related to lower respiratory infections as well. Ambient air pollutants were not related to respiratory deaths in the population of children involved in this study, but data suggests that that PM10 ambient levels might increase the risk of respiratory mortality in infants less than one year old. An increase in respiratory mortality was noted among infants from the lowest socio-economic status (SES) group. This report emphasizes the need for implementing cost effective interventions to control existing air pollution problems and to prevent the situation from worsening. 22 refs., 27 tabs., 5 figs

    Elimination of state laws that preempt local antismoking ordinances is a national health objective. However, the tobacco industry and its supporters have continued to pursue state-level preemption of local tobacco control ordinances as part of an apparent strategy to avoid the diffusion of grassroots antismoking initiatives. And, an increasing number of challenges to local ordinances by the tobacco industry and persons supported by the tobacco industry are being decided in state supreme courts and courts of appeals. The outcomes of seemingly similar cases about the validity of local smoke-free air ordinances vary significantly by state. This paper examines the common and unique aspects of the decisions and the potential implications of court rulings on preemption for future state tobacco control efforts and achievement of national health objectives around the elimination of preemption. Using a search strategy developed for the Centers for Disease Control and Prevention's State Tobacco Activities Tracking and Evaluation (STATE) System, cases where a state or federal appellate level court made a finding on the validity of a local smoke-free air ordinance or regulation were identified in 19 states. In contrast to previous studies, we found that cases in approximately half of states were decided for local governments. We also found that across the states, courts were considering similar factors in their decisions including the extent to which: (1) the local government possessed the authority to pass the ordinance, (2) the ordinance conflicted with the state constitution, and (3) state statutes preempt the ordinance.

    In China, combustion of fossil fuels and biomass has produced serious air pollution that does harm to human health. Based on dose-response relationships derived from epidemiological studies, the authors calculated the number of deaths and people with health problems which were thought to be attributable to China's air pollution in the year of 2000. In order to estimate the corresponding economic impacts from the national point of view, the general equilibrium approach was selected as an analysis tool for this study. A computable general equilibrium (CGE) model was constructed involving 39 sectors and 32 commodities.The human capital approach (HCA) was also used for comparison. The economic burden of disease for people estimated by HCA was equivalent to 1.26‰ (ranging from 0.44‰ to 1.84‰) of China's gross domestic product (GDP). China's GDP loss estimated by the general equilibrium approach reached 0.38‰ (ranging from 0.16‰ to 0.51‰). The difference between the two approaches and the implications of the results were discussed.

    Full Text Available Objective. The aim of this study was to identify household-specific factors associated with respiratory symptoms and to study the perceived impact of indoor air pollution (IAP as a health issue. Methods. An IRB-approved, voluntary, anonymous 23-item survey was conducted in Spanish at a medical outreach clinic in June 2012 and at the homes of survey respondents N=79. Comparative analyses were performed to investigate relationships between specific house characteristics and respiratory complaints. Results. Seventy-nine surveys were completed. Respiratory symptoms were frequently reported by survey respondents: 42% stated that smoke in their household caused them to have watery eyes, 42% reported household members with coughs within the past two weeks, and 25% stated that there were currently household members experiencing difficulty in breathing. Stove location and kitchen roof construction material were significantly associated with frequency of respiratory symptoms. The vast majority used firewood as their major fuel type. Most respondents indicated that neither indoor air quality was a problem nor did it affect their daily life. Conclusions. Respiratory complaints are common in Yoro, Honduras. Stove location and kitchen roof construction material were significantly associated with frequency of respiratory symptoms; this may have implications for efforts to improve respiratory health in the region.

    2008-05-01

    A robust methodology was developed to compute population-weighted daily measures of ambient air pollution for use in time-series studies of acute health effects. Ambient data, including criteria pollutants and four fine particulate matter (PM) components, from monitors located in the 20-county metropolitan Atlanta area over the time period of 1999-2004 were normalized, spatially resolved using inverse distance-square weighting to Census tracts, denormalized using descriptive spatial models, and population-weighted. Error associated with applying this procedure with fewer than the maximum number of observations was also calculated. In addition to providing more representative measures of ambient air pollution for the health study population than provided by a central monitor alone and dampening effects of measurement error and local source impacts, results were used to evaluate spatial variability and to identify air pollutants for which ambient concentrations are poorly characterized. The decrease in correlation of daily monitor observations with daily population-weighted average values with increasing distance of the monitor from the urban center was much greater for primary pollutants than for secondary pollutants. Of the criteria pollutant gases, sulfur dioxide observations were least representative because of the failure of ambient networks to capture the spatial variability of this pollutant for which concentrations are dominated by point source impacts. Daily fluctuations in PM of particles less than 10 microm in aerodynamic diameter (PM10) mass were less well characterized than PM of particles less than 2.5 microm in aerodynamic diameter (PM2.5) mass because of a smaller number of PM10 monitors with daily observations. Of the PM2.5 components, the carbon fractions were less well spatially characterized than sulfate and nitrate both because of primary emissions of elemental and organic carbon and because of differences in measurement techniques used to assess

    This study determined the health effects of ambient air pollutants in two grade school populations in Akron, Ohio. One school is adjacent to industry and has elevated levels of sulfur dioxide (SO/sub 2/) and moderate levels of nitrogen dioxide (NO/sub 2/), while the other school is 4 km east and unpolluted. This study was designed in this manner for two purposes: (1) to identify and monitor ambient levels of air pollutants in an area proximal to the grade school so that the levels could be accurately assessed, and (2) to determine baseline pulmonary function values and questionnaire responses from the parents indicating any acute and/or chronic respiratory problem in the child. Ninety-five percent of the children enrolled in this study lived within 2 km of the schools and aerometric stations, thus providing for careful control in the study design. The results of this study indicate that SO/sub 2/ and NO/sub 2/ levels are significantly higher in the school adjacent to industry. Although pulmonary function data were not significantly different between schools, the frequency of questionnaire responses to acute and chronic pulmonary problems was greater in the children at the school adjacent to industry. The data tend to indicate early pulmonary effects of air pollution in children living adjacent to industry and exposed to elevated levels of SO/sub 2/ and NO/sub 2/. We suggest that additional longitudinal work that carefully monitors total suspended particulates, NO/sub 2/, SO/sub 2/, and health data should be conducted to confirm these results.

    2014-05-01

    Since 2007, more than half of the world's population live in urban areas. Urban atmospheres are dominated by pollutants associated with vehicular emissions. Transport emissions are an important source of non-methane volatile organic compounds (NMVOCs) emissions, species of high interest because of their negative health effects and their contribution to the formation of secondary pollutants responsible for photochemical smog. NMVOCs emissions are generally not very well represented in emission inventories and their speciation presents a high level of uncertainty. In general, emissions from South American countries are still quite unknown for the international community, and usually present a high degree of uncertainty due to the lack of available data to compile emission inventories. Within the Inter-American Institute for Global Change Research (IAI, www.iai.int) projects, UMESAM (Urban Mobile Emissions in South American Megacities) and SAEMC (South American Emissions, Megacities and Climate, http://saemc.cmm.uchile.cl/), the effort was made to compute on-road transport emission inventories for South American megacities, namely Bogota, Buenos Aires, Lima, Sao Paulo and Santiago de Chile, considering megacities as urban agglomerations with more than 5 million inhabitants. The present work is a continuation of these projects, with the aim to extend the calculated NMVOCs emissions inventory into the individual species required by CTMs. The on-road mobile sector of the metropolitan area of Buenos Aires (MABA), Argentina, accounted for 70 Gg of NMVOCs emissions for 2006, without considering two-wheelers. Gasoline light-duty vehicles were responsible for 64% of NMVOCs emissions, followed by compressed natural gas (CNG) light-duty vehicles (22%), diesel heavy-duty vehicles (11%) and diesel light-duty vehicles (7%). NMVOCs emissions were speciated according to fuel and technology, employing the European COPERT (Ntziachristos & Samaras, 2000) VOCs speciation scheme for

  4. Quantification of years of life lost attributable to chronic air pollution exposure in a health impact assessment: the case of Nantes

    International Nuclear Information System (INIS)

    Background: When French regional planning for air quality first began, exposure-response functions from time-series studies were used to assess the short-term health impact of urban air pollution. The World Health Organisation also suggests that exposure-response functions from cohort studies be taken into account to evaluate the effects of chronic exposure and to quantify the prematurity of deaths related to chronic exposure to air pollution. This work characterizes the long term effects of air pollution in Nantes by considering years of life lost as well as the number of attributable deaths. methods: the study population is classified in birth cohorts. for each cohort, 2 survival curves are built based on current mortality conditions: the first is built for current exposure to air pollution and the second for exposure to a lower reference level of air pollution. The area between the 2 curves represents years of life lost attributable to urban air pollution. results: the estimated number of premature deaths due to air pollution is approximately 56, or about 2% of the deaths of those older than 30 years. The health impact on the Nantes population is estimated at 27.2 years of life lost attributable to urban air pollution in 1999 and 2388.1 years of life lost for the 1999-2008 period. This amounts to a decrease of roughly 4 months in the life expectancy of those aged 30 years. Conclusion: This study, which also identifies and discusses relevant errors and uncertainty, confirmed that air pollution in Nantes has significant health effects and that chronic exposure plays an essential role in this impact. the number of years of life lost and the reduction in life expectancy provide new reasons to reject the assumption that health effects are limited to the premature deaths of terminally-ill people. the expected health gains in Nantes associated with reduced although still moderate air pollution levels are on the same scale as, and possibly better than, those found in 9

Furthermore, effects in the lungs, e.g. inflammatory effects, have not been substantiated at indoor relevant concentrations. Some VOCs, including formaldehyde, in combination may under certain environmental and occupational conditions result in reported sensory irritation. The odour thresholds of several VOCs are low enough to influence the perceived air quality that result in a number of acute effects from reported sensory irritation in eyes and airways and deterioration of performance. The odour perception (air quality) depends on a number of factors that may influence the odour impact. There is neither clear indication that office dust particles may cause sensory effects, even not particles spiked with glucans, aldehydes or phthalates, nor lung effects; some inflammatory effects may be observed among asthmatics. Ozone-initiated terpene reaction products may be of concern in ozone-enriched environments (≥0.1mg/m(3)) and elevated limonene concentrations, partly due to the production of formaldehyde. Ambient particles may cause cardio-pulmonary effects, especially in susceptible people (e.g. elderly and sick people); even, short-term effects, e.g. from traffic emission and candle smoke may possibly have modulating and delayed effects on the heart, but otherwise adverse effects in the airways and lung functions have not been observed. Secondary organic aerosols generated in indoor ozone-initiated terpene reactions appear not to cause adverse effects in the airways; rather the gaseous products are relevant. Combined exposure to particles and ozone may evoke effects in subgroups of asthmatics. Based on an analysis of thresholds for odour and sensory irritation selected compounds are recommended for measurements to assess the indoor air quality and to minimize

    In most studies correlating health outcomes with air pollution, personal exposure assignments are based on measurements collected at air-quality monitoring stations not coinciding with health data locations. In such cases, interpolators are needed to predict air quality in unsampled locations and to assign personal exposures. Moreover, a measure of the spatial uncertainty of exposures should be incorporated, especially in urban areas where concentrations vary at short distances due to changes in land use and pollution intensity. These studies are limited by the lack of literature comparing exposure uncertainty derived from distinct spatial interpolators. Here, we addressed these issues with two interpolation methods: regression Kriging (RK) and ordinary Kriging (OK). These methods were used to generate air-quality simulations with a geostatistical algorithm. For each method, the geostatistical uncertainty was drawn from generalized linear model (GLM) analysis. We analyzed the association between air quality and birth weight. Personal health data (n=227) and exposure data were collected in Sines (Portugal) during 2007-2010. Because air-quality monitoring stations in the city do not offer high-spatial-resolution measurements (n=1), we used lichen data as an ecological indicator of air quality (n=83). We found no significant difference in the fit of GLMs with any of the geostatistical methods. With RK, however, the models tended to fit better more often and worse less often. Moreover, the geostatistical uncertainty results showed a marginally higher mean and precision with RK. Combined with lichen data and land-use data of high spatial resolution, RK is a more effective geostatistical method for relating health outcomes with air quality in urban areas. This is particularly important in small cities, which generally do not have expensive air-quality monitoring stations with high spatial resolution. Further, alternative ways of linking human activities with their

    Workplace bans on smoking are interventions to reduce exposure to secondhand smoke (SHS) to try to prevent harmful health effects. The Portuguese Government on January 1, 2008, introduced the first national law banning smoking in public workplaces, including restaurants. The main aim of this study was to examine the impact of this law on indoor air quality (IAQ) in restaurants and on the respiratory and sensory health of restaurant workers. Concentrations of respirable suspended particulate matter (RSP), total volatile organic compounds (TVOC), carbon monoxide (CO), and carbon dioxide (CO2) in 10 restaurants were measured and compared before and after the ban. Benzene (C6H6) concentrations were also measured in all restaurants. Fifty-two and twenty-eight restaurant workers, respectively, answered questionnaires on exposure to SHS, and respiratory and sensory symptoms in the pre- and post-ban phases. There was a statistically significant decrease in RSP, CO, TVOC, and C6H6 concentrations after the ban. Additionally, in both phases the monitored CO2 concentrations greatly exceeded 1800 mg x m(-3), suggesting inefficient ventilation of the indoor spaces. Between pre- and post-ban phases a significant reduction in self-reported workplace SHS exposure was also observed after the enforcement of the law, as well as a significant marked reduction in dry, itching, irritated, or watery eyes, nasal problems, sore or dry throat, cough, wheeze, and headache. This study provides, in a single investigation, comparison of IAQ and respiratory health in Portugal before and after the introduction of the smoke-free law, the first data reported in the literature to our knowledge. Our findings suggest that a total workplace smoking ban results in a significant reduction in indoor air pollution and an improvement in the respiratory health of restaurant workers. These observations may have implications for policymakers and legislators currently considering the nature and extent of their

  11. Work place air particulate monitoring of automobile workshops for public health and safety

    International Nuclear Information System (INIS)

    Twenty-eight pairs of coarse and fine air particulate samples were collected in front of an automotive workshop located at Tasmasipabad on Chaklala Road in Rawalpindi using a Gent sampler and polycarbonate filters. These samples were collected during the period; 7th to 27th of April 2009. The gravimetric data (PM2.5 and PM10) were obtained for these samples and were found to exceed the Pakistani standards. Black carbon (BC) was also determined using reflectance measurements and it was found that BC contributed significantly more to the fine mass than to the coarse fraction; i.e. ∼10 to ∼3 %, respectively. This is not surprising as soot is emitted by combustion processes and is usually found in the fine particulate mass. Using instrumental neutron activation analysis technique all 28 pairs of filters were analyzed for >30 elements. Major elements, in the coarse mass fraction, include Al, K, Fe, Sr, Na, and Zn implying soil as the major source while BC was found to be a higher contributor of PM2.5. An episode of high PM2.5 was observed on the 18th of April 2009. Back trajectory analysis showed that the air mass originated from the Middle East where a dust storm was in progress over Iraq.

    2014-01-01

    The general aim of this study was to assess the possibility of including elements of environmental health education within the curriculum of a school located in a shantytown of Buenos Aires city, Argentina. An environmental health education campaign was designed to introduce school-aged children to the problems posed by the lack of environmental sanitation, by using rodents as indicators of environmental disorder. The methodology implemented consisted of a lecture and two practical activities where the participating children were the evaluators of their neighborhood environment, recording the environmental factors that indicate direct or indirect presence of rodents and carrying out a survey about rodents among their neighbors. To assess the impact of the activities, an anonymous questionnaire was performed with the students before and after the campaign. The results showed that students were able to identify the man-made factors which favor the presence of rodents and were encouraged to propose strategies related to environmental sanitation to reduce rodent proliferation and the transmission of their parasites. This study demonstrated the feasibility of performing environmental health education campaigns in school-aged children by using practical activities to stimulate observation, participation, and comprehensive understanding of the problems posed by urban pests.

    We developed regionalized characterization factors (CFs) for human health damage from particulate matter (PM2.5) and ozone, and for damage to vegetation from ozone, at the global scale. These factors can be used in the impact assessment phase of an environmental life cycle assessment. CFs express the overall damage of a certain pollutant per unit of emission of a precursor, i.e. primary PM2.5, nitrogen oxides (NOx), ammonia (NH3), sulfur dioxide (SO2) and non-methane volatile organic compounds (NMVOCs). The global chemical transport model TM5 was used to calculate intake fractions of PM2.5 and ozone for 56 world regions covering the whole globe. Furthermore, region-specific effect and damage factors were derived, using mortality rates, background concentrations and years of life lost. The emission-weighted world average CF for primary PM2.5 emissions is 629 yr kton-1, varying up to 3 orders of magnitude over the regions. Larger CFs were obtained for emissions in central Asia and Europe, and smaller factors in Australia and South America. The world average CFs for PM2.5 from secondary aerosols, i.e. NOx, NH3, and SO2, is 67.2 to 183.4 yr kton-1. We found that the CFs for ozone human health damage are 2-4 orders of magnitude lower compared to the CFs for damage due to primary PM2.5 and PM2.5 precursor emissions. Human health damage due to the priority air pollutants considered in this study was 1.7·10-2 yr capita-1 worldwide in year 2010, with primary PM2.5 emissions as the main contributor (62%). The emission-weighted world average CF for ecosystem damage due to ozone was 2.5 km2 yr kton-1 for NMVOCs and 8.7 m2 yr kg-1 for NOx emissions, varying 2-3 orders of magnitude over the regions. Ecosystem damage due to the priority air pollutants considered in this study was 1.6·10-4 km2 capita-1 worldwide in 2010, with NOx as the main contributor (72%). The spatial range in CFs stresses the importance of including spatial variation in life cycle impact

  16. Waterpipes and e-cigarettes: Impact of alternative smoking techniques on indoor air quality and health

    Fromme, Hermann; Schober, Wolfgang

    2015-04-01

    Waterpipe (WP) smoking is growing as an alternative to cigarette smoking, especially in younger age groups. E-cigarette use has also increased in recent years. A majority of smokers mistakenly believe that WP smoking is a social entertainment practice that leads to more social behavior and relaxation and that this type of smoking is safe or less harmful and less addictive than cigarette smoking. In reality, WP smokers are exposed to hundreds of toxic substances that include known carcinogens. High exposures to carbon monoxide and nicotine are major health threats. Persons exposed to secondhand WP smoke are also at risk. There is growing evidence that WP smoke causes adverse effects on the pulmonary and cardiovascular systems and is responsible for cancer. E-cigarettes are marketed as a smokeless and safe way to inhale nicotine without being exposed to the many toxic components of tobacco cigarettes, and as an aid to smoking cessation. In fact, consumers (vapers) and secondhand vapers can be exposed to substantial amounts of VOC, PAH or other potentially harmful substances. Of major health concern is the inhalation of fine and ultrafine particles formed from supersaturated 1,2-propanediol vapor. Such particles can be deposited in the deeper parts of the lung and may harm the respiratory system or increase the risk of acquiring asthma. More research on the safety of e-cigarettes needs to be conducted to ensure a high level of public health protection in the long-term.

    The early twentieth century saw the rise of vacation camps for frail children as educational and health-giving experiences provided by medical and philanthropic organizations. This article analyzes some of these early experiences, seen here as the predecessors of social tourism, in the Province of Buenos Aires. A combination of written sources are examined, mainly institutional reports, periodicals such as the Monitor de la Educación Común - published by the Consejo Nacional de Educación (National Board of Education) - or laws, with photographs and plans for different examples. I argue that these buildings were both physical and cultural "brands" in the places where they were located, and that their architectural structure encapsulated ideas about leisure space and cures in unique natural environments.

    The mass concentrations of airborne particles in the atmospheric, indoor, and industrial environments are regulated by air quality standards. Epidemiological studies show that there are significant positive correlations between particle mass concentrations and adverse health effects. In this context nanoparticles in the air, which are defined as particles with a diameter (Dp) of less than 50 nm or 100 nm for engineered ones, are gaining increasing attention despite a small contribution to the mass of total airborn particles. Contrary to the mass concentration the number concentrations of atmospheric nanoparticles are quite high in most cases. Moreover there is limited toxicological information on nanoparticles, although the deposition rate of nanoparticles in the respiratory region is known to be relatively high. Accordingly there are a lot of debates about what metric is best to depict the size distribution of nanoparticles, number, surface area, or mass. In this paper, we report methods for measurement of nanoparticles on the basis of those metrics. We also report sources of nanoparticle in the environment and occupational settings. The high number concentration of nanoparticles of 20-30 nm modal diameters have been documented at roadsides. Diesel-powered vehicles are major sources of those nanoparticles in the urban atmosphere. Engineered nanoparticles generate in some occupational settings in the handling processes such as bagging and cleaning with vacuum cleaners. PMID:18567372

  20. Evaluation of dust-related health hazards associated with air coring at G-Tunnel, Nevada Test Site

    International Nuclear Information System (INIS)

    The Yucca Mountain Project was established to evaluate the potential for storing high-level radioactive wastes in geologic formations. Hydrologists recommended that drilling or coring in support of characterization tests be performed dry. Dry drilling, or air coring, presents a concern about health protection for the drilling personnel. The rock generally has a high silica content, and natural zeolites are abundant. Some zeolites are fibrous, leading to concerns that inhalation may result in asbestos-like lung diseases. An industrial hygiene study (IH) was conducted as part of an air coring technical feasibility test. The IH study found the potential for exposures to airborne silica and nuisance dusts to be within regulatory requirements and determined the commercial dust control equipment monitored to be effective when used in conjunction with a good area ventilation system and sound IH practices. Fibrous zeolites were not detected. Recommendations for the Yucca Mountain studies are (1) dust collection and control equipment equivalent or superior to that monitored must be used for any dry drilling activity and must be used with good general dilution ventilation and local exhaust ventilation provided on major emission sources; (2) good industrial hygiene work practices must be implemented, including monitoring any area where zeolitic fibers are suspect; and (3) a study should be conducted to determine the biological effects of the fibrous zeolite, mordenite. 25 refs., 17 figs., 14 tabs

    Full Text Available Background: Industrial air pollution is a growing challenge to humane health, especially in developing countries, where there is no systematic monitoring of air pollution. Given the importance of the availabil­ity of valid information on population exposure to air pollutants, it is important to design an optimal Air Quality Monitoring Network (AQMN for assessing population exposure to air pollution and predicting the magnitude of the health risks to the population. Methods: A multi-pollutant method (implemented as a MATLAB program was explored for configur­ing an AQMN to detect the highest level of pollution around an oil refinery plant. The method ranks potential monitoring sites (grids according to their ability to represent the ambient concentra­tion. The term of cluster of contiguous grids that exceed a threshold value was used to calculate the Station Dosage. Selection of the best configuration of AQMN was done based on the ratio of a sta­tion’s dosage to the total dosage in the network. Results: Six monitoring stations were needed to detect the pollutants concentrations around the study area for estimating the level and distribution of exposure in the population with total network effi­ciency of about 99%. An analysis of the design procedure showed that wind regimes have greatest effect on the location of monitoring stations. Conclusion: The optimal AQMN enables authorities to implement an effective program of air quality management for protecting human health.

    Satellite remote sensing (RS) has emerged as a cutting edge approach for estimating ground level ambient air pollution. Previous studies have reported a high correlation between ground level PM2.5 and NO2 estimated by RS and measurements collected at regulatory monitoring sites. The current study examined associations between air pollution and adverse respiratory and allergic health outcomes using multi-year averages of NO2 and PM2.5 from RS and from regulatory monitoring. RS estimates were derived using satellite measurements from OMI, MODIS, and MISR instruments. Regulatory monitoring data were obtained from Canada's National Air Pollution Surveillance Network. Self-reported prevalence of doctor-diagnosed asthma, current asthma, allergies, and chronic bronchitis were obtained from the Canadian Community Health Survey (a national sample of individuals 12 years of age and older). Multi-year ambient pollutant averages were assigned to each study participant based on their six digit postal code at the time of health survey, and were used as a marker for long-term exposure to air pollution. RS derived estimates of NO2 and PM2.5 were associated with 6e10% increases in respiratory and allergic health outcomes per interquartile range (3.97 mg m3 for PM2.5 and 1.03 ppb for NO2) among adults (aged 20e64) in the national study population. Risk estimates for air pollution and respiratory/ allergic health outcomes based on RS were similar to risk estimates based on regulatory monitoring for areas where regulatory monitoring data were available (within 40 km of a regulatory monitoring station). RS derived estimates of air pollution were also associated with adverse health outcomes among participants residing outside the catchment area of the regulatory monitoring network (p < 0.05).

  7. Trading our health: Ontario Power Generation's plan to violate its air pollution reduction commitment

    International Nuclear Information System (INIS)

    Amid growing concerns about nitrogen oxide (Nox) emissions, the Ontario Clean Air Alliance is recommending in this report that the Ontario government restrict Nox emissions from Ontario Power Generation (OPG) in the year 2000 and not let the corporation meet its emissions cap by on a net basis by retiring Pilot Emission Reduction Trading (PERT) Nox emission reduction credits. Instead the alliance believes the Ontario government should require OPG to achieve emissions compliance by curtailing coal-fired electricity exports, purchasing renewable and natural-gas electricity and promoting energy efficiency. OPG's inventory of PERT Nox reduction credits are assessed against whether they will cause an increase in the year 2000 as a result of trading. Ontario Power Generation's Nox emissions are a central chemical component of acid rain and smog and are produced from its coal-fired electricity generators. The utility would like to achieve Nox reductions by establishing demand management programs which would reduce the demand for electricity by 5200 megawatts (MW), by purchasing 3100 MW of non-utility generation and by undertaking combustion process modifications at its Lambton and Nanticoke coal-fired generating stations. It has not met its 2000 demand management and non-utility generation targets, and specifically, as of December 31, 1998, Ontario Hydro's successor companies demand management programs have only reduced electricity demand by approximately 1300 MW. Furthermore, the successor companies will have only approximately 1700 MW of non-utility generation capacity under contract by December 31, 1999. The report describes the criteria for ensuring that Nox emissions trading will not lead to a net increase in Ontario's emissions in any given year, and a description is included of why the 'Draft Rules for Emission Trading in Ontario' rules do not meet these criteria. Permitting OPG to use its PERT credits to meet its Nox cap, will allow them to increase coal

    A high-resolution assessment of health impacts from air pollution and related external cost has been conducted for Denmark using the integrated EVA model system. The EVA system is based on the impact-pathway methodology, where the site-specific emissions will result, via atmospheric transport and chemistry, in a concentration distribution, which together with detailed population data, is used to estimate the population-level exposure. Using exposure-response functions and economic valuations, the exposure is transformed into impacts on human health and related external costs. In this study we have used a coupling of two chemistry transport models to calculate the air pollution concentration at different domain and scales; the Danish Eulerian Hemispheric Model (DEHM) to calculate the air pollution levels in the Northern Hemisphere with a resolution down to 5.6 km x 5.6 km and the Urban Background Model (UBM) to further calculate the air pollution in Denmark at 1 km x 1 km resolution using results from DEHM as boundary conditions. Both the emission data as well as the population density has been represented in the model system with the same high resolution. Previous health impact assessments related to air pollution have been made on a lower resolution. In this study, the integrated model system, EVA, has been used to estimate the health impacts and related external cost for Denmark at a 1 km x 1 km resolution. New developments of the integrated model system will be presented as well as the development of health impacts and related external costs in Europe and Denmark over a period of 36 years (1979-2014).

    Full Text Available Air pollution still exceeds safe limits worldwide, particularly in big metropolitans, despite regular monitoring facilities and measures taken. It is usually originated from industrial activities, fossil fuel use in domestic settings and vehicle exhaust emission. Although there is a decrease in air pollution in big cities of Turkey due to use of natural gas, it is still a serious health concern. In Diyarbakır, because of a rapid increase in its population recently, wrong urbanisation and a relative increase in industrialisation, air pollution leads to dangerous levels, particularly in the winter. Epidemiological studies from all over the world, and Turkey have reported a close relation between air pollution and respiratory morbidity and mortality. Studies investigating the mechanisms underlying respiratory effects of air pollution demonstrated that pollutants lead to increased respiratory symptoms, decreased respiratory function and induce inflammatory changes in airways. In vitro studies have shown that air pollutants exert their effects by causing cellular injury directly, and by activating intracellular oxidative pathways indirectly. The attempts to reduce air pollution levels have been implemented in Turkey and worldwide. In order to solve the problem in Diyarbakır, several measures such as prevention the use of out standardized fuel, use of reliable burning techniques, and a close car emission monitoring system need to be implemented.

    Veles with its geographic position, atmospheric specifics, urban and industrial concentration with wrong location of the Lead and Zink Smelter-opposite to the Wind Rose, multiplied by inconvenient power plants is analysedhydro-topographic factors has all predispositions for huge and continuous air pollution (3 decades) with specific agent-lead. There is statistically high significant difference by Student t-test (t = 15.14; p 3), related to the control area-v.lvankovci (x = 0.03 μg/m3) . Registered average annual concentration of lead in the ambient air is 89% higher than the recommended value from WHO and EU (0.5 μg/m3). Increased concentration of lead in the ambient air, represent high risk factor for the health of the exposed children population in the city of Veles. There has been registered statistically significant difference (t = 3.96; p 20 μg/dl). Pearson test of correlation between registered values of EEG and the intelligence quotient, has shown negative moderate correlation (r = -0.31; p < 0.05). With Pearson test of correlation between registered values of EEG and blood-lead levels, has been got low correlation (r = 0.12; p < 0.05). It can be concluded that all registered outputs in the examined children can be reversible, and still they are in compensatory phase without clear clinical sign of disease. Electromyography has not shown any disorder in neuromuscular conductivity in selected children. Pearson test of correlation between registered values of SEMG and blood-lead levels, has shown negative correlation (r = -0.07; p < 0.05). Results shows that selected children are with normal activity of the autonomous nervous system and they adequately respond to the stress situation. It can be concluded that there is an obvious environmental-health risk in Veles, with enough evidences for the pollution of the environment in Veles, as well the impact of higher blood-lead levels to NAG, IQ, graphomotoric ability in the examined children, as well to EEG in

    The basic aim of research focusing on the accounting of external effects is to provide estimates for the possible benefits of environmental policy projects. There is a demand within the field of environmental economic analysis for evaluations and estimates of the economic benefits arising from pollution reductions. Where benefits arising out of reduced emissions of harmful substances are concerned, these can be estimated according to the avoided damage costs associated with negative pollution impacts. A scientifically based method designed for this purpose has been developed in the pan-European ExternE project via the EU research programmes. The ExternE project has been implemented with the aim of estimating monetary values for externalities attached to air pollution accruing from energy production and transport. For this purpose, complex model-based environmental impact estimations have been coupled with corresponding monetary valuations via the modelling tool, Ecosense. A problem arising in relation to Ecosense methodology has been that externalities are often of local nature - pollution impact depending on the particular locality of the emission and dispersal characteristics in the surrounding environment. Therefore, the economic estimation of the impacts of pollution is based on a location-specific modelling system. (BA)

  12. Fine particulate matter in the indoor air of barbeque restaurants: Elemental compositions, sources and health risks

    International Nuclear Information System (INIS)

    Cooking is a significant source of indoor particulate matter that can cause adverse health effects. In this study, a 5-stage cascade impactor was used to collect particulate matter from 14 restaurants that cooked with charcoal in Kocaeli, the second largest city in Turkey. A total of 24 elements were quantified using ICP-MS. All of the element contents except for Mn were higher for fine particles (PM2.5) than coarse particles (PM>2.5), and the major trace elements identified in the PM2.5 included V, Se, Zn, Cr, As, Cu, Ni, and Pb. Principle component analysis (PCA) and enrichment factor (EF) calculations were used to determine the sources of PM2.5. Four factors that explained over 77% of the total variance were identified by the PCA. These factors included charcoal combustion, indoor activities, crustal components, and road dust. The Se, As, Cd, and V contents in the PM2.5 were highly enriched (EF > 100). The health risks posed by the individual metals were calculated to assess the potential health risks associated with inhaling the fine particles released during charcoal cooking. The total hazard quotient (total HQ) for a PM2.5 of 4.09 was four times greater than the acceptable limit (i.e., 1.0). In addition, the excess lifetime cancer risk (total ELCR) for PM2.5 was 1.57 × 10−4, which is higher than the acceptable limit of 1.0 × 10−6. Among all of the carcinogenic elements present in the PM2.5, the cancer risks resulting from Cr(VI) and As exposure were the highest (i.e., 1.16 × 10−4 and 3.89 × 10−5, respectively). Overall, these results indicate that the lifetime cancer risk associated with As and Cr(VI) exposure is significant at selected restaurants, which is of concern for restaurant workers. - Highlights: • Particulate emissions from charcoal combustion in the BBQ restaurants were studied. • Vanadium, Se, Zn, Cr and As were found as high concentrations in PM2.5. • Charcoal combustion and indoor activities were the primary sources of the

    Nitrogen (N) and sulfur oxides (SOx) in air, land and water media are parts of tightly coupled geophysical systems resulting in multiple routes for human and ecosystem exposure. For instance, excess forms of total reactive N in water can lead to harmful algal blooms, with the depletion of oxygen and adverse impacts to aquatic ecosystem productivity in coastal estuaries. Acidic deposition can result in lost forest productivity for terrestrial ecosystem and impacts to trout and other fishery resources in inland waters. Human pulmonary health can be impaired when N and SOx in the atmosphere lead to the generation of ozone and particulate matter (PM). Atmospheric N deposition can also contribute to eutrophication of drinking water sources. The U.S. Environmental Protection Agency (USEPA) Office of Research and Development (ORD) has embarked on the development of a multi-media 'one environment' systems approach to these issues to help develop management decisions that create win-win policies. The purpose of this project is to develop a 'one environment' set of models that can inform protection of ecosystems and human health in both the current state and under future climate scenarios. The research framework focuses on three interrelated themes; coupling air quality with land use and agricultural land management, connecting the hydrosphere (i.e., coupling meteorology and hydrology) and linking the air/land/hydrosphere with ecosystem models and benefits models. We will present an overall modeling framework and then move to the presentation of on-going research results related to direct linkage of air quality with land use and agricultural land management. A modeling interface system has been developed that facilitates the simulation of field-scale agricultural land management decisions over a gridded domain at multiple grid resolutions for the Contiguous United States (CONUS) using a modified version of the USDA EPIC (Environmental Policy Integrated Climate) model.

    The neglected tropical diseases (NTDs), a group of chronic, debilitating, and poverty-promoting parasitic, bacterial, and some viral and fungal infections, are among the most common causes of illness of the poorest people living in developing countries. Abiotic environmental factors are important in determining the distribution of disease-causing vectors and their life-cycles. HyspIRI observations can be merged through a Land Data Assimilation System (LDAS) be used to drive spatially-explicit ecological models of NTD vectors distribution & life cycles. Assimilations will be driven by observational data LDAS and satellite-derived meteorological forcing data, parameter datasets, and assimilation observations. HyspIRI hyperspectral measurements would provide global measurements of surface mineralogy and biotic crusts important in accessing the impact of dust in human health. HyspIRI surface thermal measurements would also help identify the variability of dust sources due to surface moisture conditions and map mineralogy.

  16. Review of the health risks associated with nitrogen dioxide and sulfur dioxide in indoor air

    International Nuclear Information System (INIS)

    The scientific literature on the health effects of nitrogen dioxide (NO2) and sulfur dioxide (SO2) were reviewed with particular focus on the chemical and physical properties of the 2 gases and the toxicological characteristics identified in animal studies at exposure concentrations near the rate of ambient human exposures. The study also examined the expected levels of non-industrial indoor exposure of Canadians compared to other regions with similar climates. The sources of indoor pollution were also reviewed, along with the contribution of outdoor pollution to indoor levels. Results from epidemiological studies of indoor exposures in homes, offices and schools were also presented. For each pollutant, the study identified anthropogenic sources, indoor sources, toxicological characteristics, biochemistry, pulmonary effects, immune response, and other effects. Indoor sources of NO2 include gas-fired appliances, pilot lights, hot water heaters, kerosene heaters, and tobacco smoke. The impact of ventilation on both NO2 and SO2 levels was also examined. Outdoor sources such as traffic can also contribute to indoor levels, particularly in urban areas. In the case of SO2, coal heating and cooling appear to be associated in increased indoor levels. The epidemiological studies that were reviewed failed in general to indicate an association between NO2 exposure and a wide range of health impacts. The studies, however, indicate that asthmatics are more susceptible to the effects of NO2 exposure. In the case of SO2, evidence suggests that it has a chronic effect on lung function and respiratory symptoms and disease. 243 refs., 13 tabs

    Most countries in Sub-Saharan Africa including Ghana still depend extensively on unprocessed solid cooking fuels with many people exposed on a daily basis to harmful emissions and other health risks. In this study, using complementary log-log multivariate models, we estimated the health effects of exposure to smoke from unprocessed wood in four regions of Ghana while controlling for socio-environmental and socio-demographic factors. The results show that the distribution of self-reported exposure to smoke was highest among participants in the Northern region, rural dwellers, the 25-49 age groups, individuals with no education, and married women. As expected, exposure to smoke was higher in crowded households and in communities without basic social amenities. Region, residential locality, housing quality (type of roofing, floor and exterior materials), self-reported housing condition, and access to toilet facilities were associated with self-reported exposure to solid fuel smoke. Participants living in urban areas were less likely (OR = 0.82, ρ ≤ 0.01) to be exposed to solid fuel smoke compared to their rural counterparts. An inverse relationship between self-reported housing condition and exposure to solid fuel smoke was observed and persisted even after adjustments were made for confounding variables in the demographic model. In Ghana, the cost and intermittent shortages of liquefied petroleum gas and other alternative fuel sources hold implications for the willingness of the poor to shift to their use. Thus, the poorest rural populations with nearly no cash income and electricity, but with access to wood and/or agricultural waste, are unlikely to move to clean fuels or use significantly improved stoves without large subsidies, which are usually not sustainable. However, there appears to be large populations between these extremes that can be targeted by efforts to introduce improved stoves. PMID:24136388

    ABSTRACT OBJECTIVE To analyze the impact of air pollution on respiratory and cardiovascular morbidity of children and adults in the city of Vitoria, state of Espirito Santo. METHODS A study was carried out using time-series models via Poisson regression from hospitalization and pollutant data in Vitoria, ES, Southeastern Brazil, from 2001 to 2006. Fine particulate matter (PM10), sulfur dioxide (SO2), and ozone (O3) were tested as independent variables in simple and cumulative lags of up to five days. Temperature, humidity and variables indicating weekdays and city holidays were added as control variables in the models. RESULTS For each increment of 10 µg/m3 of the pollutants PM10, SO2, and O3, the percentage of relative risk (%RR) for hospitalizations due to total respiratory diseases increased 9.67 (95%CI 11.84-7.54), 6.98 (95%CI 9.98-4.17) and 1.93 (95%CI 2.95-0.93), respectively. We found %RR = 6.60 (95%CI 9.53-3.75), %RR = 5.19 (95%CI 9.01-1.5), and %RR = 3.68 (95%CI 5.07-2.31) for respiratory diseases in children under the age of five years for PM10, SO2, and O3, respectively. Cardiovascular diseases showed a significant relationship with O3, with %RR = 2.11 (95%CI 3.18-1.06). CONCLUSIONS Respiratory diseases presented a stronger and more consistent relationship with the pollutants researched in Vitoria. A better dose-response relationship was observed when using cumulative lags in polynomial distributed lag models. PMID:26982960

    The present discussion on the health effects associated with airborne fine particulate matter has lead to an increased public interest in the general framework of compilation and evaluation of clean air plans and actions plans. While the surveys of the ''old'' clean air plans of the 80ies and 90ies of the last century relied on assessment of direct and indirect effects of air pollution on human health (and ecology), theses surveys are not part of the ''new'' clean air plans according to European law. This reduction of surveys and actions directed at threshold compliance only, abandons assessing, i.e., documentation and evaluation the health status and quality of life of populations. Assessment of individual and focus group specific sensibility and vulnerability becomes possible once health related, sociodemographic and environmental data are combined. By this, unequal life chance, i.e., unimpaired health as well as reasonable strategies towards minimizing environmental injustice can be identified. As of yet it is unclear, to what extend quality of life and quality of environment of populations living in air polluted areas are attributable to socioeconomic factors. Likewise, it is not known to which degree the environmental quality of individuals and families is self determined. This has to be considered especially for children, immigrants and women. These issues i.e., environmental justice/injustice should be considered in future projects on the development of clean air plans and especially actions plans derived thereof. Scientists, government officials and physicians working in field of preventive or environmental medicine cannot agree to a limitation of the cautionary principle to the bare compliance with thresholds.

  20. Risk tradeoffs and public health protection

    International Nuclear Information System (INIS)

    Full text of publication follows: over the last 25 years, the traditional command-and-control, chemical-by-chemical environmental medium-by-environmental medium, risk-by-risk approach to protecting public health from environmental risks has worked well to greatly improve the quality of our food, air, water, and workplaces, but we are now left with the more complex problems, like urban air pollution or personal dietary behavior, that a chemical-by-chemical approach is not going to solve. Because current environmental regulatory programs have curbed the 'low-hanging fruit' and because of today's emphasis on achieving risk reductions cost-effectively, new and creative public health-based approaches to risk management are needed. Since public concern about pollution-related disease become serious in the 1960's and 1970's and regulatory agencies and laws began to proliferate, the public health goals of environmental protection have been obscured. As a society, we have made a tradeoff between environmental health and public health. The public health foundation of environmental health protection has been obscured by legalistic, technical, centralized decision-making processes that have often mistaken hazard for risk. A greater focus on public health would help us to assess aggregate risks and to target risk management resources by focusing on a problem and then identifying what is causing the problem as a guide to determining how best to solve it. Most of our current approaches start with a cause and then try to eliminate it without determining the extent to which it actually may contribute to a problem, making it difficult to set priorities among risks or to evaluate the impact of risk management actions on public health.

    Volatile organic compounds (VOCs) are common ingredients in cosmetic products which can impact human health. This study monitored 12 hairdressing salons in order to assess the individual exposure of the people working in or frequenting these environments as well as identify the main products or activities responsible for the presence of these compounds. In each site halogenated, oxygenated, aliphatic and aromatic compounds were monitored during the work week with diffusive samplers suitable for thermal desorption and analysed using GC-MS. The study of indoor-outdoor concentration ratios and a knowledge of the composition of most of the products, whether ecological or traditional, used in the hair salons verified the presence of compounds linked to hairdressing activities. In particular, compounds widely used in products for hair care as spray lacquer and foam (butane), shampoo, balms, hair masks and oils (camphene, camphor, limonene, eucalyptol, alpha pinene, 1-methoxy-2-propanol, n-butanol and menthol), and hair dye (benzyl alcohol, isopropanol, limonene, hexane and methyl ethyl ketone) were found at much higher levels inside rather than outside the salons (mean I/O > 10). The importance of this finding is linked to the potential health hazards of some of the VOCs detected. Integrated indicators of health risk were proposed in this study to assess the criticality level and rank the investigated environments accordingly. The results of this study indicate that the level of VOC concentrations was most affected by the type of products used while the size of the environment, the efficiency of air exchange and the number of customers had less impact on those levels.

  2. To what extent can China’s near-term air pollution control policy protect air quality and human health? A case study of the Pearl River Delta region

    International Nuclear Information System (INIS)

    Following a series of extreme air pollution events, the Chinese government released the Air Pollution Prevention and Control Action Plan in 2013 (China’s State Council 2013). The Action Plan sets clear goals for key regions (i.e. cities above the prefecture level, Beijing-Tianjin-Hebei Province, the Yangtze River Delta and the Pearl River Delta) and establishes near-term control efforts for the next five years. However, the extent to which the Action Plan can direct local governments’ activities on air pollution control remains unknown. Here we seek to evaluate the air quality improvement and associated health benefits achievable under the Action Plan in the Pearl River Delta (PRD) area from 2012 to 2017. Measure-by-measure quantification results show that the Action Plan would promise effective emissions reductions of 34% of SO2, 28% of NOx, 26% of PM2.5 (particulate matter less than 2.5 μm in diameter), and 10% of VOCs (volatile organic compounds). These emissions abatements would lower the PM2.5 concentration by 17%, surpassing the 15% target established in the Action Plan, thereby avoiding more than 2900 deaths and 4300 hospital admissions annually. We expect the implementation of the Action Plan in the PRD would be productive; the anticipated impacts, however, fall short of the goal of protecting the health of local residents, as there are still more than 33 million people living in places where the annual mean ambient PM2.5 concentrations are greater than 35 μg m−3, the interim target-3 of the World Health Organization (WHO). We therefore propose the next steps for air pollution control that are important not only for the PRD but also for all other regions of China as they develop and implement effective air pollution control policies.

    This paper describes results of applying the palynological and carbon isotopic analysis of the organic fraction of Total Suspended Particles (TSP) to discriminate distinct pollution sources and assess the anthropogenic impact for the investigated areas. The samples of atmospheric particles were collected in Czerniawa and Cieplice (two health resorts in Lower Silesia, SW Poland) twice a year in summer and winter season (from July 2006 to February 2008). The palynological spectra represent in the vast majority local plant communities without a noticeable contribution of long-transported plant particles. Palynological analysis revealed also differences in the specificity of the two sampling areas, i.e. the higher contribution of identified organic material in Czerniawa stands for more natural character of this site, but is also responsible for the higher allergic pressure when compared to Cieplice. The carbon isotopic composition of TSP varied seasonally ({delta}{sup 13}C value from -27.09 parts per thousand in summer to -25.47 parts per thousand in winter). The increased {delta} {sup 13}C value in winter (heating period) is most probably caused by uncontrolled contribution of coal soot. On the basis of isotopic mass balance the calculated contribution of anthropogenic organic particles in the atmosphere reached in winter season 72% in Czerniawa and 79% in Cieplice.

  5. Indoor air quality and health does fungal contamination play a significant role?

    Science.gov (United States)

    Bardana, Emil J

    2003-05-01

    Fungal contamination in buildings can vary greatly, and their presence in a dwelling does not necessarily constitute exposure. Measurement of mold spores and fragments varies depending on the methodology and instruments used. Meaningful comparison of data is rarely possible. The presence of a specific immune response to a fungal antigen only connotes that exposure to one or more related species has occurred, but not that there is a symptomatic clinical state. The response of individuals to indoor bioaerosols is complex and depends on age, gender, state of health, genetic makeup, and degree and time of bioaerosol exposure. In general, mold contamination in buildings is associated with incursion of water or moisture, which should be remedied as efficiently as possible. When disease occurs, it more likely is related to transient annoyance or irritational reactions. Allergic symptoms may be related to mold proliferation in the home environment. Because molds are encountered both indoors and outdoors, it is difficult to determine where the sensitivity initially arose and if the response is solely provoked by either an indoor or outdoor source. As an indoor allergen, mold is considered to be an infrequent participant in the induction of allergic disease when compared with housedust mites, animal dander, and cockroach allergens. Infection in healthy individuals is rare and usually is caused by an outdoor source. Building-related disease caused by mycotoxicosis has not been proved in the medical literature. PMID:12803364

    Full Text Available The indoor environment in four beauty salons located in Athens (Greece was examined in order to investigate the occupational health exposure of cosmetologists to various chemical products typically used in their work. Chemical substances chosen for investigation were volatile organic compounds (VOCs, formaldehyde, ozone and carbon dioxide. Total VOCs levels measured showed significant variation (100–1,450 μg m-3 depending on the products used and the number of treatments carried out, as well as ventilation. The main VOCs found in the salons were aromatics (toluene, xylene, esters and ketones (ethyl acetate, acetone, etc. which are used as solvents in various beauty products; terpenes (pinene, limonene, camphor, menthenol which have a particular odor and others like camphor which have specific properties. Ozone concentrations measured in all salons were quite low (0.1 and 13.3 μg m-3 and formaldehyde concentrations detected were lower than the detection limit of the method in all salons (<0.05 ppm. Carbon dioxide levels ranged between 402 and 1,268 ppm, depending on the number of people present in the salons during measurements and ventilation. Cosmetologists may be exposed to high concentrations of a mixture of volatile organic compounds although these levels could be decreased significantly by following certain practices such as good ventilation of the areas, closing the packages of the beauty products when not in use and finally selecting safer beauty products without strong odor.

    Research on air pollutant emissions associated with unconventional oil and gas (UOG) development has grown significantly in recent years. Empirical investigations have focused on the identification and measurement of oil and gas air pollutants [e.g. volatile organic compounds (VOCs), particulate matter (PM), methane] and the influence of UOG on local and regional ambient air quality (e.g. tropospheric ozone). While more studies to better characterize spatial and temporal trends in exposure among children and newborns near UOG sites are needed, existing research suggests that exposure to air pollutants emitted during lifecycle operations can potentially lead to adverse respiratory outcomes in this population. Children are known to be at a greater risk from exposure to air pollutants, which can impair lung function and neurodevelopment, or exacerbate existing conditions, such as asthma, because the respiratory system is particularly vulnerable during development in-utero, the postnatal period, and early childhood. In this article, we review the literature relevant to respiratory risks of UOG on infants and children. Existing epidemiology studies document the impact of air pollutant exposure on children in other contexts and suggest impacts near UOG. Research is sparse on long-term health risks associated with frequent acute exposures - especially in children - hence our interpretation of these findings may be conservative. Many data gaps remain, but existing data support precautionary measures to protect the health of infants and children. PMID:27171386

    The CA Department of Pesticide Regulation (CDPR) and the CA Air Resources Board monitored 40 pesticides, including five degradation products, in Parlier, CA, to determine if its residents were exposed to any of these pesticides and, if so, in what amounts. They included 1,3-dichloropropene, acrolein, arsenic, azinphos-methyl, carbon disulfide, chlorpyrifos and its degradation product, chlorthalonil, copper, cypermethrin, diazinon and its degradation product, dichlorvos, dicofol, dimethoate and its degradation product, diuron, endosulfan and its degradation product, S-ethyl dipropylcarbamothioate (EPTC), formaldehyde, malathion and its degradation product, methyl isothiocyanate (MITC), methyl bromide, metolachlor, molinate, norflurazon, oryzalin, oxyfluorfen, permethrin, phosmet, propanil, propargite, simazine, SSS-tributylphosphorotrithioate, sulfur, thiobencarb, trifluralin, and xylene. Monitoring was conducted 3 days per week for a year. Twenty-three pesticides and degradation products were detected. Acrolein, arsenic, carbon disulfide, chlorpyrifos, copper, formaldehyde, methyl bromide, MITC, and sulfur were detected in more than half the samples. Since no regulatory ambient air standards exist for these pesticides, CDPR developed advisory, health-based non-cancer screening levels (SLs) to assess acute, subchronic, and chronic exposures. For carcinogenic pesticides, CDPR assessed risk using cancer potency values. Amongst non-carcinogenic agricultural use pesticides, only diazinon exceeded its SL. For carcinogens, 1,3-dichloropropene concentrations exceeded its cancer potency value. Based on these findings, CDPR has undertaken a more comprehensive evaluation of 1,3-dichloropropene, diazinon, and the closely related chlorpyrifos that was frequently detected. Four chemicals-acrolein, arsenic, carbon disulfide, and formaldehyde-sometimes used as pesticides were detected, although no pesticidal use was reported in the area during this study.

  10. Health effects of air pollution in Japan and comparison of hazard indices of effluents from fossil fuel and nuclear plants

    International Nuclear Information System (INIS)

    The dose-response relationship between prevalence rates of chronic bronchitis and sulphur dioxide are introduced. Based on the Air Quality Standards, various efforts have been made to reduce the concentrations of sulphur dioxide in the atmosphere. Consequently, the sulphur dioxide concentrations decreased. However, the atmospheric concentrations of nitrogen dioxide tended to increase gradually. It was therefore considered important to study the health effects of nitrogen dioxide. In six different areas in Japan with varying atmospheric concentrations of nitrogen dioxide, an extensive epidemiological survey was conducted with over 10.000 schoolchildren 6 to 15 years old during the period 1979 to 1981. The prevalence rate of asthma was estimated to be 4.7 % for males and 2.1 % for females in the high NO2 concentration area, and 1.9 % for males and 0.9% for females in the low NO2 concentration area. For asthma-like symptoms, 12.2 % for males and 11.9 % for females was observed at the high NO2 concentration area, and 7.1 % for males and 5.9 % for females in the low NO2 concentration area. The natural radioactivity from fossil-fuel power plants is also discussed. From the comparison of hazard indices of effluents from fossil-fuel and nuclear power plants, the hazard indices of air pollution by SO2 and NO2 may be considered most significant. In decision-making on environmental protection and safety, it should be carefully considered whether a reduction of one type of risk might increase another type of risk. In order to ensure clean environment and to prevent acid rain disaster on forest it may be important to encourage development of cleaner nuclear power plants with smaller hazard indices. (Author)

  12. Exposure-response functions for health effects of ambient air pollution applicable for China. A meta-analysis

    International Nuclear Information System (INIS)

    Assessing the benefits of projects and policies to reduce air pollution requires quantitative knowledge about the relationship between exposure to air pollution and public health. This article proposes exposure-response functions for health effects of PM10 and SO2 pollution in China. The functions are based on Chinese epidemiological studies, and cover mortality, hospital admissions, and chronic respiratory symptoms and diseases. We derive the following coefficients for acute effects: a 0.03% (S.E. 0.01) and a 0.04% (S.E. 0.01) increase in all-cause mortality per μg/m3 PM10 and SO2, respectively, a 0.04% (S.E. 0.01) increase in cardiovascular deaths per μg/m3 for both PM10 and SO2, and a 0.06% (S.E. 0.02) and a 0.10% (S.E. 0.02) increase in respiratory deaths per μg/m3 PM10 and SO2, respectively. For hospital admissions due to cardiovascular diseases the obtained coefficients are 0.07% (S.E. 0.02) and 0.19% (S.E. 0.03) for PM10 and SO2, respectively, whereas the coefficients for hospital admissions due to respiratory diseases are 0.12% (S.E. 0.02) and 0.15% (S.E. 0.03) for PM10 and SO2, respectively. Exposure-response functions for the impact of long-term PM10 levels on the prevalence of chronic respiratory symptoms and diseases are derived from the results of cross-sectional questionnaire surveys, and indicate a 0.31% (S.E. 0.01) increase per μg/m3 in adults and 0.44% (S.E. 0.02) per μg/m3 in children. With some exceptions, Chinese studies report somewhat lower exposure-response coefficients as compared to studies in Europe and USA

    The 14th International Congress on Combustion By-Products and Their Health Effects was held in Umeå, Sweden from June 14th to 17th, 2015. The Congress, mainly sponsored by the National Institute of Environmental Health Sciences Superfund Research Program and the Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning, focused on the "Origin, fate and health effects of combustion-related air pollutants in the coming era of bio-based energy sources". The international delegates included academic and government researchers, engineers, scientists, policymakers and representatives of industrial partners. The Congress provided a unique forum for the discussion of scientific advances in this research area since it addressed in combination the health-related issues and the environmental implications of combustion by-products. The scientific outcomes of the Congress included the consensus opinions that: (a) there is a correlation between human exposure to particulate matter and increased cardiac and respiratory morbidity and mortality; (b) because currently available data does not support the assessment of differences in health outcomes between biomass smoke and other particulates in outdoor air, the potential human health and environmental impacts of emerging air-pollution sources must be addressed. Assessment will require the development of new approaches to characterize combustion emissions through advanced sampling and analytical methods. The Congress also concluded the need for better and more sustainable e-waste management and improved policies, usage and disposal methods for materials containing flame retardants. PMID:26906006

  14. Impact of heavy traffic on the local air quality and public health. The (im)possibility to define a safe distance to a highway

    International Nuclear Information System (INIS)

    An overview is provided of the results of measuring campaigns and model calculations near Dutch highways and roads. It is demonstrated that the contribution of the highways to traffic related air pollution depends on the type of component that is measured. The contribution of particulate matter measured as PM10 or PM2.5 is relatively limited, whereas the contribution of components such as soot, elementary carbon, nitrogen dioxide and very small matter is significantly larger. Insight is also given with regard to scientific literature focusing on the relation between health and traffic-related air pollution. It shows that there is enough ground for assuming a connection between exposure to traffic emissions and adverse health effects. Based on these studies a range cannot be provided within and outside which health effects were or were not found. [mk

    2015-08-18

    Marginal analysis is the usual approach to environmental economic assessment, for instance, of health-related external costs due to energy-associated air pollutant emissions. However, nonlinearity exists in all steps of their assessment, i.e., atmospheric dispersion, impact assessment, and monetary valuation. Dedicated assessments thus appear necessary when evaluating large systems or their changes such as in green accounting or the implications of economy-wide energy transitions. Corresponding approaches are reviewed. Tools already exist that allow assessing a marginal change (e.g., one power plant's emissions) for different background emission scenarios that merely need to be defined and implemented. When assessing nonmarginal changes, the top-down approach is considered obsolete, and four variants of the bottom-up approach with different application domains were identified. Variants 1 and 2 use precalculated external cost factors with different levels of sophistication, suitable for energy systems modeling, optimizing for social (i.e., private and external) costs. Providing more reliable results due to more detailed modeling, emission sources are assessed individually or jointly in variants 3 and 4, respectively. Aiming at considering nonlinearity more fully and simultaneously following marginal analysis principles, I propose a variant 3-based approach, subdividing an aggregate (i.e., a nonmarginal change) into several smaller changes. Its strengths and drawbacks, notably the associated effort, are discussed. PMID:26237285

    Remotely piloted aircraft (RPA), also known as drones, have been used extensively in the recent conflicts in Iraq and Afghanistan. Although RPA pilots in the U.S. Air Force (USAF) have reported high levels of stress and fatigue, rates of mental health (MH) diagnoses and counseling in this population are unknown. We calculated incidence rates of 12 specific MH outcomes among all active component USAF RPA pilots between 1 October 2003 and 31 December 2011, and by various demographic and military variables. We compared these rates to those among all active component USAF manned aircraft (MA) pilots deployed to Iraq/Afghanistan during the same period. The unadjusted incidence rates of all MH outcomes among RPA pilots (n=709) and MA pilots (n=5,256) were 25.0 per 1,000 person-years and 15.9 per 1,000 person-years, respectively (adjusted incidence rate ratio=1.1, 95% confidence interval=0.9-1.5; adjusted for age, number of deployments, time in service, and history of any MH outcome). Th ere was no significant difference in the rates of MH diagnoses, including post-traumatic stress disorder, depressive disorders, and anxiety disorders between RPA and MA pilots. Military policymakers and clinicians should recognize that RPA and MA pilots have similar MH risk profiles. PMID:23550927

  17. Towards a multidisciplinary and integrated strategy in the assessment of adverse health effects related to air pollution: The case study of Cracow (Poland) and asthma

    International Nuclear Information System (INIS)

    Complex interaction between anthropogenic activities, air quality and human health in urban areas, such as in Cracow sustains the need for the development of an interdisciplinary and integrated risk-assessment methodology. In such purpose, we propose a pilot study performed on asthmatics and based on a combined use of a biomarker, such as metallothionein 2A (MT-2A) in the characterization of human exposure to one or a mixture of pollutants and of Geographical Information Systems (G.I.S.) which integrates climatic and urban anthropogenic parameters in the assessment of spatio-temporal dispersion of air pollutants. Considering global incidence of air pollution on asthma and on peripheral blood lymphocytes MT-2A expression should provide a complementary information on biological risks linked to urban anthropogenic activities. Such study would help for the establishment of a sustainable development in urban areas that can maintain the integrity of air quality and preserve human health. - An integrative risk methodology based on both geographic and molecular biological approaches is proposed for the assessment of asthmatics exposure to urban air pollution

    Full Text Available Background: Air pollutants of iron- and steel-making operations have historically been an environmental and health hazard. These pollutants include gaseous substances such as sulfur oxide, nitrogen dioxide, and carbon monoxide. The Iran National Steel Industrial Group beam rolling mills factory has two production lines viz. line 630 and line 650, with different beam production capabilities and is capable of producing different types of beams. Materials and Methods: A retrospective cross-sectional study on 400 workers in different exposure levels to environmental pollution was performed during 2005 to determine the mean value of respirable particulate matter (RPM concentrations and its effects on the health status of workers. To elicit information regarding the health status of the worker, the National Institute for Occupational Safety and Health standard questionnaire was used. Fisher′s exact test was performed to assess the relative risk (RR of exposure to air pollution on cardiovascular diseases, chest tightness, cough, difficulty in retention, i.e. loss of memory, tension, occupational fatigue, and occupational stress in exposed workers. Results: There was significant difference in RPM pollution level between two product lines. The RR of exposure to air pollution on cardiovascular diseases, chest tightness, cough, difficulty in retention, i.e. loss of memory, tension, occupational fatigue, and occupational stress in exposed workers were 2.78, 2.44, 2.15, 1.92, 1.57, 3.90, and 2.09, respectively.

  3. Assessment of past, present and future health-cost externalities of air pollution in Europe and the contribution from international ship traffic using the EVA model system

    2013-03-01

    Full Text Available An integrated model system, EVA (Economic Valuation of Air pollution, based on the impact-pathway chain has been developed, to assess the health-related economic externalities of air pollution resulting from specific emission sources or sectors. The model system can be used to support policy-making with respect to emission control. In this study, we apply the EVA system to Europe, and perform a more detailed assessment of past, present, and future health-cost externalities of the total air pollution levels in Europe (including both natural and anthropogenic sources, represented by the years 2000, 2007, 2011, and 2020. We also assess the contribution to the health-related external costs from international ship traffic with special attention to the international ship traffic in the Baltic and North Seas, since special regulatory actions on sulphur emissions, called SECA (sulphur emission control area, have been introduced in these areas,. We conclude that despite efficient regulatory actions in Europe in recent decades, air pollution still constitutes a serious problem to human health, hence the related external costs are considerable. The total health-related external costs for the whole of Europe is estimated at 803 bn Euro yr−1 for the year 2000, decreasing to 537 bn Euro yr−1 in the year 2020. We estimate the total number of premature deaths in Europe in the year 2000 due to air pollution to be around 680 000 yr−1, decreasing to approximately 450 000 in the year 2020. The contribution from international ship traffic in the Northern Hemisphere was estimated to 7% of the total health-related external costs in Europe in the year 2000, increasing to 12% in the year 2020. In contrast, the contribution from international ship traffic in the Baltic Sea and the North Sea decreases 36% due to the regulatory efforts of reducing sulphur emissions from ship traffic in SECA.

    Guang-Hui Dong

    Full Text Available BACKGROUND: Males and females exhibit different health responses to air pollution, but little is known about how exposure to air pollution affects juvenile respiratory health after analysis stratified by allergic predisposition. The aim of the present study was to assess the relationship between air pollutants and asthmatic symptoms in Chinese children selected from multiple sites in a heavily industrialized province of China, and investigate whether allergic predisposition modifies this relationship. METHODOLOGY/PRINCIPAL FINDINGS: 30139 Chinese children aged 3-to-12 years were selected from 25 districts of seven cities in northeast China in 2009. Information on respiratory health was obtained using a standard questionnaire from the American Thoracic Society. Routine air-pollution monitoring data was used for particles with an aerodynamic diameter ≤10 µm (PM(10, sulfur dioxide (SO(2, nitrogen dioxides (NO(2, ozone (O(3 and carbon monoxide (CO. A two-stage regression approach was applied in data analyses. The effect estimates were presented as odds ratios (ORs per interquartile changes for PM(10, SO(2, NO(2, O(3, and CO. The results showed that children with allergic predisposition were more susceptible to air pollutants than children without allergic predisposition. Amongst children without an allergic predisposition, air pollution effects on asthma were stronger in males compared to females; Current asthma prevalence was related to PM(10 (ORs = 1.36 per 31 µg/m(3; 95% CI, 1.08-1.72, SO(2 (ORs = 1.38 per 21 µg/m(3; 95%CI, 1.12-1.69 only among males. However, among children with allergic predisposition, more positively associations between air pollutants and respiratory symptoms and diseases were detected in females; An increased prevalence of doctor-diagnosed asthma was significantly associated with SO(2 (ORs = 1.48 per 21 µg/m(3; 95%CI, 1.21-1.80, NO(2 (ORs = 1.26 per 10 µg/m(3; 95%CI, 1.01-1.56, and current asthma with

    The epidemiological surveillance of sanitary effects linked to the air pollution seems to be the best tool to estimate their impact and to keep a close eye on the short term effects of the ambient pollution on the populations health. In any case, the potential sanitary impact of pollution peaks does not conceal the importance of sanitary effects linked to the background pollution. These peaks constitute sanitary alert signals but are not inevitably the predominant risk for public health. A targeting on these peaks can lead to neglect actions of prevention and to induce these policies towards strategies that will not be the most efficient in term of reduction of mortality attributable to air pollution.

    This paper describes the effect of airborne dust on health. Among fiber dusts in usual houses, cotton-derived dust occupies 71%, paper-derived 11%, chemical fiber-derived 10%, hair-derived 5%, and others occupy the rest. Cotton, silk and hair can be allergens which are antigens causing allergy. Cigarette smoke composes of various gaseous substances, and by-flow smoke from the ignition part is hazardous. The dust generation by smoking provides ten times of standard concentration in a Japanese 6 rush-mat room per one cigarette. Asbestos can be a carcinogen due to their accumulation. They do not have an allowable standard for absolute safety, and they should be removed by manual method under an obligation. This paper also describes the effect of ticks and mold particles as allergen dusts on health, and the measures for them. Pollens and their measures are described. Air cleaners are usually used for removing airborne dusts in the houses with high air-tightness. Nearly 100% of particles with a diameter more than several {mu}m can be collected with a fan filter-type air cleaner. However, the collecting performance is decreased to 70 to 80% for submicron particles such as cigarette smoke. An ion-type air cleaner can not be so promising. 24 refs., 5 figs., 5 tabs.

    The prevalence of asthma and allergic diseases has increased dramatically during the past few decades not only in industrialized countries. Urban air pollution from motor vehicles has been indicated as one of the major risk factors responsible for this increase.Although genetic factors are important in the development of asthma and allergic diseases, the rising trend can be explained only in changes occurred in the environment. Despite some differences in the air pollution profile and decreasing trends of some key air pollutants, air quality is an important concern for public health in the cities throughout the world.Due to climate change, air pollution patterns are changing in several urbanized areas of the world, with a significant effect on respiratory health.The observational evidence indicates that recent regional changes in climate, particularly temperature increases, have already affected a diverse set of physical and biological systems in many parts of the world. Associations between thunderstorms and asthma morbidity in pollinosis subjects have been also identified in multiple locations around the world.Allergens patterns are also changing in response to climate change and air pollution can modify the allergenic potential of pollens especially in presence of specific weather conditions.The underlying mechanisms of all these interactions are not well known yet. The consequences on health vary from decreases in lung function to allergic diseases, new onset of diseases, and exacerbation of chronic respiratory diseases.Factor clouding the issue is that laboratory evaluations do not reflect what happens during natural exposition, when atmospheric pollution mixtures in polluted cities are inhaled. In addition, it is important to recall that an individual's response to pollution exposure depends on the source and components of air pollution, as well as meteorological conditions. Indeed, some air pollution-related incidents with asthma aggravation do not depend

    Full Text Available In recent years, an important number of studies, carried out in different cities, have found that, even bellow air quality levels considered as safe, increases in the levels of air pollution are associated with harmful effects on health. Epidemiology has played a major role in the evaluation of the impact of air pollution on health, since it provides proofs of the association among human populations within natural conditions. Also, toxicology and clinical sciences provide convincing proofs on the etiopathogenic mechanisms of such associations.The purpose of the evaluation of impact on health is to quantify the expected number of people whose health is affected due to a specific exposure situation. In Europe, since three years ago, the APHEIS project, with 26 participating cities, has established an environmental health surveillance system which includes a database of air pollution and health. This is aimed at quantifying the effects of air pollution on public health at local, national and European levels, as well as distributing standardised reports about air pollution impact on public health.En los últimos años un número importante de estudios realizados en distintas ciudades han encontrado que, aún por debajo de los niveles de calidad del aire considerados como seguros, los incrementos de los niveles de la contaminación atmosférica se asocian con efectos nocivos sobre la salud. La epidemiología ha jugado un papel crucial en la evaluación de impacto en salud de la contaminación atmosférica al proporcionar pruebas de la asociación en poblaciones humanas en condiciones naturales. Por su parte la toxicología y las ciencias clínicas aportan pruebas convincentes acerca de los mecanismos etiopatogénicos de dichas asociaciones.El propósito de la evaluación de impacto en salud es cuantificar el número esperado de personas con un efecto en salud que puede ser atribuido a una situación específica de exposición.

  18. 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.

    Exposure studies rely on detailed characterization of air quality, either from sparsely located routine ambient monitors or from central monitoring sites that may lack spatial representativeness. Alternatively, some studies use models of various complexities to characterize local-scale air quality, but often with poor representation of background concentrations. A hybrid approach that addresses this drawback combines a regional-scale model to provide background concentrations and a local-scal...

Este artículo intenta realizar una revisión crítica de los efectos de la contaminación intra y extradomiciliaria sobre la salud humana, poniendo especial énfasis en la situación de los habitantes de ciudades chilenas con niveles críticamente altos de contaminación atmosférica. Los contaminantes atmosféricos riesgosos para la salud humana son el material particulado inhalable (PM10; PM2,5 y PM0,1 y compuestos químicos gaseosos tales como dióxido de nitrógeno, ozono, dióxido de azufre y monóxido de carbono. El aire intradomiciliario contiene una variedad de compuestos nocivos que derivan de múltiples fuentes. Las más importantes son el humo de cigarrillo, artefactos de calefacción y para cocción de alimentos y los agentes biológicos y sus sub-productos. La exposición a contaminantes del aire no solo puede aumentar la tasa de morbilidad sino la tasa de mortalidad como también puede aumentar el número de ingresos hospitalarios de pacientes con síntomas respiratorios y cardiovasculares. La contaminación del aire es importante en la determinación de la calidad de vida de niños menores, ancianos y en pacientes con enfermedades respiratorias y cardiovasculares.

    This study examines short-term relationships between doctors' house calls and urban air pollution in Greater Paris for the period 1991-1995. Poisson regressions using nonparametric smoothing functions controlled for time trend, seasonal patterns, pollen counts, influenza epidemics, and weather. The relationship between asthma visits and air pollution was stronger for children. A relative risk (RRP95/P5) of 1.32 [95% confidence interval (CI) = 1.17-1.47)] was observed for an increase from the 5th to the 95th percentile (7-51 micrograms/m3) in daily concentrations of black smoke (BS). The risks for 24-hr sulfur dioxide and nitrogen dioxide levels were in the same range. Cardiovascular conditions, considered globally, showed weaker associations than angina pectoris/myocardial infarction, for which RRP95/P5 was 1.63 (95% CI = 1.10-2.41) in relation to ozone ambient levels. Eye conditions were exclusively related to ozone (RRP95/P5 = 1.17, 95% CI 1.02-1.33). Asthma visits and ozone showed an interaction with minimum temperature: an effect was observed only at 10 degrees C or higher. In two-pollutant models including BS with, successively, SO2, NO2, and O3, only BS and O3 effects remained stable. Along with mortality and hospital admissions, house call activity data, available on a regular basis, may be a sensitive indicator for monitoring health effects related to air pollution.

    International Nuclear Information System (INIS)

    This study was designed to accomplish two objectives. The first was to provide to the US Air Force and the regulatory community quantitative procedures that they might want to consider using for addressing uncertainty and variability in exposure to better characterize potential health risk. Such methods could be used at sites where populations may now or in the future be faced with using groundwater contaminated with low concentrations of the chemical trichloroethylene (TCE). The second was to illustrate and explain the application of these procedures with respect to available data for TCE in ground water beneath an inactive landfill site that is undergoing remediation at Beale Air Force Base in California. The results from this illustration provide more detail than the more traditional conservative deterministic, screening-level calculations of risk, also computed for purposes of comparison. Application of the procedures described in this report can lead to more reasonable and equitable risk-acceptability criteria for potentially exposed populations at specific sites

  6. Trade-offs between energy cost and health impact in a regional coupled energy-air quality model: the LEAQ model

    International Nuclear Information System (INIS)

    This letter presents a methodology for an integrated energy-air quality model in a cost and impact trade-off framework, applicable at the regional scale. ETEM (the Energy Technology Environmental Model) minimizes the energy cost at a given level of sectoral emissions. An efficient, reduced-order Eulerian air quality model (TAPOM-Lite) simulates some consecutive days where the meteorological conditions are favorable to the occurrence of an ozone episode. A health impact function has been developed to perform the feedback from ozone concentrations to the energy cost. The decomposition optimization problem is solved using an Oracle-based technique. We report on an implementation for the Grand Duchy of Luxembourg, varying the parameters of the impact function.

  8. Implications of different approaches for characterizing ambient air pollutant concentrations within the urban airshed for time-series studies and health benefits analyses

    Full Text Available Abstract Background In time-series studies of the health effects of urban air pollutants, decisions must be made about how to characterize pollutant levels within the airshed. Methods Emergency department visits for pediatric asthma exacerbations were collected from Atlanta hospitals. Concentrations of carbon monoxide, nitrogen dioxide, ozone, sulfur dioxide, particulate matter less than 10 microns in diameter (PM10, particulate matter less than 2.5 microns in diameter (PM2.5, and the PM2.5 components elemental carbon, organic carbon, and sulfate were obtained from networks of ambient air quality monitors. For each pollutant we created three different daily metrics. For one metric we used the measurements from a centrally-located monitor; for the second we averaged measurements across the network of monitors; and for the third we estimated the population-weighted average concentration using an isotropic spatial model. Rate ratios for each of the metrics were estimated from time-series models. Results For pollutants with relatively homogeneous spatial distributions we observed only small differences in the rate ratio across the three metrics. Conversely, for spatially heterogeneous pollutants we observed larger differences in the rate ratios. For a given pollutant, the strength of evidence for an association (i.e., chi-square statistics tended to be similar across metrics. Conclusions Given that the chi-square statistics were similar across the metrics, the differences in the rate ratios for the spatially heterogeneous pollutants may seem like a relatively small issue. However, these differences are important for health benefits analyses, where results from epidemiological studies on the health effects of pollutants (per unit change in concentration are used to predict the health impacts of a reduction in pollutant concentrations. We discuss the relative merits of the different metrics as they pertain to time-series studies and health benefits

    Health impacts of air pollution may differ depending on sex, education, socioeconomic status (SES), location at time of death, and other factors. In São Paulo, Brazil, questions remain regarding roles of individual and community characteristics. We estimate susceptibility to air pollution based on individual characteristics, residential SES, and location at time of death (May 1996-December 2010). Exposures for particulate matter with an aerodynamic diameter ≤ 10 μm (PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3) were estimated using ambient monitors. Time-stratified case-crossover analysis was used with individual-level health data. Increased risk of non-accidental, cardiovascular, and respiratory mortality were associated with all pollutants (P 11 years education were lower than estimates for those with 0 years education for NO2, SO2, and CO (1.66% (95% confidence interval: 0.23%, 3.08%); 1.51% (0.51%, 2.51%); and 2.82% (0.23%, 5.35%), respectively). PM10 cardiovascular mortality effects were (3.74% (0.044%, 7.30%)) lower for the high education group (> 11 years) compared with the no education group. Positive, significant associations between pollutants and mortality were observed for in-hospital deaths, but evidence of differences in air pollution-related mortality risk by location at time of death was not strong.

  12. Overview of ozone human exposure and health risk analyses used in the U.S. EPA's review of the ozone air quality standard.

    1999-03-04

    This paper presents an overview of the ozone human exposure and health risk analyses developed under sponsorship of the U.S. Environmental Protection Agency (EPA). These analyses are being used in the current review of the national ambient air quality standards (NAAQS) for ozone. The analyses consist of three principal steps: (1) estimating short-term ozone exposure for particular populations (exposure model); (2) estimating population response to exposures or concentrations (exposure-response or concentration-response models); and (3) integrating concentrations or exposure with concentration-response or exposure-response models to produce overall risk estimates (risk model). The exposure model, called the probabilistic NAAQS exposure model for ozone (pNEM/03), incorporates the following factors: hourly ambient ozone concentrations; spatial distribution of concentrations; ventilation state of individuals at time of exposure; and movement of people through various microenvironments (e.g., outdoors, indoors, inside a vehicle) of varying air quality. Exposure estimates are represented by probability distributions. Exposure-response relationships have been developed for several respiratory symptom and lung function health effects, based on the results of controlled human exposure studies. These relationships also are probabilistic and reflect uncertainties associated with sample size and variability of response among subjects. The analyses also provide estimates of excess hospital admissions in the New York City area based on results from an epidemiology study. Overall risk results for selected health endpoints and recently analyzed air quality scenarios associated with alternative 8-hour NAAQS and the current 1-hour standard for outdoor children are used to illustrate application of the methodology.

    Non-CO2 air pollutants from motor vehicles have traditionally been controlled to protect air quality and health, but also affect climate. We use global composition climate modelling to examine the integrated impacts of adopting stringent European on-road vehicle-emission standards for these pollutants in 2015 in many developing countries. Relative to no extra controls, the tight standards lead to annual benefits in 2030 and beyond of 120,000-280,000 avoided premature air pollution-related deaths, 6.1-19.7 million metric tons of avoided ozone-related yield losses of major food crops, $US0.6-2.4 trillion avoided health damage and $US1.1-4.3 billion avoided agricultural damage, and mitigation of 0.20 (+0.14/-0.17) C of Northern Hemisphere extratropical warming during 2040-2070. Tighter vehicle-emission standards are thus extremely likely to mitigate short-term climate change in most cases, in addition to providing large improvements in human health and food security. These standards will not reduce CO2 emissions, however, which is required to mitigate long-term climate change.

    Full Text Available Ambient air pollution causes a considerable disease burden, particularly in South Asia. The objective of the study is to test the feasibility of applying the environmental burden of disease method at state level in India and to quantify a first set of disease burden estimates due to ambient air pollution in Kerala. Particulate Matter (PM was used as an indicator for ambient air pollution. The disease burden was quantified in Years of Life Lost (YLL for the population (30 + years living in urban areas of Kerala. Scenario analyses were performed to account for uncertainties in the input parameters. 6108 (confidence interval (95% CI: 4150–7791 of 81,636 total natural deaths can be attributed to PM, resulting in 96,359 (95% CI: 65,479–122,917 YLLs due to premature mortality (base case scenario, average for 2008–2011. Depending on the underlying assumptions the results vary between 69,582 and 377,195 YLLs. Around half of the total burden is related to cardiovascular deaths. Scenario analyses show that a decrease of 10% in PM concentrations would save 15,904 (95% CI: 11,090–19,806 life years. The results can be used to raise awareness about air quality standards at a local level and to support decision-making processes aiming at cleaner and healthier environments.

    Health inequities are a common problem for all countries and are the result of not only adverse social conditions but also poor public policies. Today chronic diseases represent the most relevant threats and are a current challenge. Parasitic infections, a leading cause of child morbidity affecting low-income populations, can be transmitted because of an unhealthy environment. Notwithstanding, scarce data have been published on the epidemiological profile of intestinal parasitoses in asymptomatic children living in shantytowns. Vulnerable populations settled in slums are growing in Argentina, particularly in Buenos Aires city. Consequently, this work intended to screen healthy carriers of enteric parasites and determine the epidemiologic profile in asymptomatic children residing in one of those communities, to explore risk factors associated with the transmission of parasites, and to initiate a basic health education campaign to promote healthy behavior in the community. Fecal samples (n = 138) were analyzed by conventional parasitological methods and a survey gathered data on symptoms, family composition, and environmental and hygiene-related variables. High prevalence of feco-orally-transmitted parasitoses (83.3%) and polyparasitism were remarkable findings. The main environmental health determinants were those related to excreta disposal and water provision. Health promotion actions were performed through the diffusion of a set of posters with iconic images and brief messages for health education. Results suggest the need for an environmental sanitation policy to complement health promotion actions. It is essential to spread the results of investigations that address inequities and social determinants of health in order to integrate data with local political processes and alert on acceptable actions for developing appropriate interventions.

    We have developed and successfully tested two prototypes of detectors of dangerous gases based on wire-type counters operating in air in avalanche mode: one is for radon (Rn) detection whereas the other one is for the detection of gases with an ionization potential less than the air components. Due to the operation in pulse counting mode these prototypes have sensitivities comparable to (in the case of the Rn detector) or much higher than (in the case of the detector for low ionization gases) the best commercial devices currently available on the market. We believe that due to their high sensitivity, simplicity and low cost such new detectors will find massive applications. One of them, discussed in this paper, could be the on-line monitoring of Rn for the prediction of earthquakes. (C) 2010 Elsevier B.V. All rights reserved.

    "Getting the prices right" through internalizing external costs is a guiding principle of environmental policy making, one recent example being the EU Clean Air Policy Package released at the end of 2013. It is supported by impact assessments, including monetary valuation of environmental and health damages. For over 20 years, related methodologies have been developed in Europe in the Externalities of Energy (ExternE) project series and follow-up activities. In this study, we aim at analyzing the main methodological developments over time from the 1990s until today with a focus on classical air pollution-induced human health damage costs. An up-to-date assessment including the latest European recommendations is also applied. Using a case from the energy sector, we identify major influencing parameters: differences in exposure modeling and related data lead to variations in damage costs of up to 21%; concerning risk assessment and monetary valuation, differences in assessing long-term exposure mortality risks together with assumptions on particle toxicity explain most of the observed changes in damage costs. These still debated influencing parameters deserve particular attention when damage costs are used to support environmental policy making. PMID:25664763

    In a study of 'pseudocroup' (acute stenosing laryngotracheitis) carried out by the Institute for Water, Soil and Air Hygiene of the Federal Health Office, 2356 pseudocroup attacks (July 1982 to September 1984) with stationary treatment in one of the 5 children's hospitals in Berlin (West) were analysed in a retrospective part as well as 537 attacks (October 1984 to March 1985) in a prospective part. The study was supplemented by an 'observational part' with indoor measurements of NO/sub 2/, relative humidity, temperature and diary records of the health status of 40 children (in 30 homes) suffering from repeated pseudocroup attacks. Stationary treatment due to pseudocroup has been more frequent than expected in the central districts of Berlin, where children are exposed to higher mean SO/sub 2/ concentrations. In winter 1984/85 with smog alarms in January 1985, SO/sub 2/ concentrations during the days directly preceding pseudocroup attacks were higher than in the following few days. In the observational part, we found a higher frequency of respiratory diseases in periods with higher indoor NO/sub 2/ concentrations. Virus infections, as has been supposed before, stand out as the main factor inducing pseudocroup attacks. Air quality plays a role as a partial cause.

Original articles relating to atmospheric pollution and human health published between 1995 and 2009 were retrieved from the PubMed database and analyzed. This study included only articles dealing with atmospheric pollutants resulting primarily from vehicle emissions. Three researchers were involved in the final selection of the studies, and the chosen articles were approved by at least two of the three researchers. Of the 84 non-Brazilian studies analyzed, 80 showed an association between atmospheric pollution and adverse effects on human health. Moreover, 66 showed evidence of adverse effects on human health, even at levels below the permitted emission standards. Three studies mentioned public policies aimed at changing emission standards. Similarly, the 29 selected Brazilian studies reported adverse associations with human health, and 27 showed evidence of adverse effects even at levels below the legally permitted emission standards. Of these studies, 16 mentioned public policies aimed at changing emission standards. Based on the Brazilian and non-Brazilian scientific studies that have been conducted, it can be concluded that, even under conditions that are compliant with Brazilian air quality standards, the concentration of atmospheric pollutants in Brazil can negatively affect human health. However, as little discussion of this topic has been generated, this finding demonstrates the need to incorporate epidemiological evidence into decisions regarding legal regulations and to discuss the public policy implications in epidemiological studies.

    Understanding how historical climate and land cover changes have affected tropospheric ozone in East Asia would help constrain the large uncertainties associated with future East Asian air quality projections. We perform a series of simulations using a global chemical transport model driven by assimilated meteorological data and a suite of land cover and land use data to examine the public health effects associated with changes in climate, land cover, land use, and anthropogenic emissions between the 5-year periods 1981-1985 and 2007-2011 in East Asia. We find that between these two periods land cover change alone could lead to a decrease in summertime surface ozone by up to 4 ppbv in East Asia and ~ 2000 fewer ozone-related premature deaths per year, driven mostly by enhanced dry deposition resulting from climate- and CO2-induced increase in vegetation density, which more than offsets the effect of reduced isoprene emission arising from cropland expansion. Climate change alone could lead to an increase in summertime ozone by 2-10 ppbv in most regions of East Asia and ~ 6000 more premature deaths annually, mostly attributable to warming. The combined impacts (-2 to +12 ppbv) show that while the effect of climate change is more pronounced, land cover change could offset part of the climate effect and lead to a previously unknown public health benefit. While the changes in anthropogenic emissions remain the largest contributor to deteriorating ozone air quality in East Asia over the past 30 years, we show that climate change and land cover changes could lead to a substantial modification of ozone levels, and thus should come into consideration when formulating future air quality management strategies. We also show that the sensitivity of surface ozone to land cover change is more dependent on dry deposition than on isoprene emission in most of East Asia, leading to ozone responses that are quite distinct from that in North America, where most ozone

    UV radiation is an essential driver for the formation of photochemical smog, which includes ground-level ozone and particulate matter (PM). Recent analyses support earlier work showing that poor outdoor air quality is a major environmental hazard as well as quantifying health effects on regional and global scales more accurately. Greater exposure to these pollutants has been linked to increased risks of cardiovascular and respiratory diseases in humans and is associated globally with several million premature deaths per year. Ozone also has adverse effects on yields of crops, leading to loss of billions of US dollars each year. These detrimental effects also may alter biological diversity and affect the function of natural ecosystems. Future air quality will depend mostly on changes in emission of pollutants and their precursors, but changes in UV radiation and climate will contribute as well. Significant reductions in emissions, mainly from the energy and transportation sectors, have already led to improved air quality in many locations. Air quality will continue to improve in those cities/states that can afford controls, and worsen where the regulatory infrastructure is not available. Future changes in UV radiation and climate will alter the rates of formation of ground-level ozone and photochemically-generated particulate matter and must be considered in predictions of air quality. The decrease in UV radiation associated with recovery of stratospheric ozone will, according to recent global atmospheric model simulations, lead to increases in ground-level ozone at most locations. If correct, this will add significantly to future ground-level ozone trends. However, the spatial resolution of these global models is insufficient to inform policy at this time, especially for urban areas. UV radiation affects the atmospheric concentration of hydroxyl radicals, ˙OH, which are responsible for the self-cleaning of the atmosphere. Recent measurements confirm that, on a

    Full Text Available This paper throws light on household cooking related exposures and level of indoor air pollutants (particulate matter and gaseous pollutants CO, CO2, SO2, NO, NO2 in different exposure area from the different types of cooking fuels used. Still the prevalence of biomass fuels exists in Indian households, combustion of which releases higher levels of solid and gaseous pollutants during the cooking hours. The indoor air pollutants (SPM, CO, CO2, SO2, NO, NO2 were measured with handy samplers with different types of cooking fuels (biomass and LPG. For this purpose 50 randomly selected sampled of the indoor air quality were monitored. The results suggests that average concentration of PM10 (394.07 μg/m3 and gaseous pollutants (CO-3.15 ppm, CO2- 492.63 ppm, SO2-0.56 ppm, NO-0.58 ppm, NO2-0.52 ppm were highest during cooking hours with biofuels cooking places. Thus, not only the women who are involved in cooking suffer from the various ill effects, but also other family members who are inside the house during cooking hours also face exposures. The recorded SPM (114.73 μg/m3 for PM10 and gaseous pollutants (CO-1.34 ppm, CO2-379.83 ppm, SO2-0.52 ppm, NO-0.54 ppm, NO2-0.52 ppm in LPG using households were lower as compared to biomass fuel using households. Due to the LPG efficiency the time involved in cooking is also low leading to less exposure to the pollutants released.

    Full Text Available Abstract Background Traffic-related air pollution is a potential risk factor for human respiratory health. A Geographical Information System (GIS approach was used to examine whether distance from a main road (the Tosco-Romagnola road affected respiratory health status. Methods We used data collected during an epidemiological survey performed in the Pisa-Cascina area (central Italy in the period 1991-93. A total of 2841 subjects participated in the survey and filled out a standardized questionnaire on health status, socio-demographic information, and personal habits. A variable proportion of subjects performed lung function and allergy tests. Highly exposed subjects were defined as those living within 100 m of the main road, moderately exposed as those living between 100 and 250 m from the road, and unexposed as those living between 250 and 800 m from the road. Statistical analyses were conducted to compare the risks for respiratory symptoms and diseases between exposed and unexposed. All analyses were stratified by gender. Results The study comprised 2062 subjects: mean age was 45.9 years for men and 48.9 years for women. Compared to subjects living between 250 m and 800 m from the main road, subjects living within 100 m of the main road had increased adjusted risks for persistent wheeze (OR = 1.76, 95% CI = 1.08-2.87, COPD diagnosis (OR = 1.80, 95% CI = 1.03-3.08, and reduced FEV1/FVC ratio (OR = 2.07, 95% CI = 1.11-3.87 among males, and for dyspnea (OR = 1.61, 95% CI = 1.13-2.27, positivity to skin prick test (OR = 1.83, 95% CI = 1.11-3.00, asthma diagnosis (OR = 1.68, 95% CI = 0.97-2.88 and attacks of shortness of breath with wheeze (OR = 1.67, 95% CI = 0.98-2.84 among females. Conclusion This study points out the potential effects of traffic-related air pollution on respiratory health status, including lung function impairment. It also highlights the added value of GIS in environmental health research.

  14. Indoor air pollution

    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

    Preparing data for medical research can be challenging, detail oriented, and time consuming. Transcription errors, missing or nonsensical data, and records not applicable to the study population may hamper progress and, if unaddressed, can lead to erroneous conclusions. In addition, study data may be housed in multiple disparate databases and complex formats. Merging methods may be incomplete to obtain temporally synchronized data elements. We created a comprehensive database to explore the general hypothesis that environmental and occupational factors influence health outcomes and risk-taking behavior among active duty Air Force personnel. Several databases containing demographics, medical records, health survey responses, and safety incident reports were cleaned, validated, and linked to form a comprehensive, relational database. The final step involved removing and transforming personally identifiable information to form a Health Insurance Portability and Accountability Act compliant limited database. Initial data consisted of over 62.8 million records containing 221 variables. When completed, approximately 23.9 million clean and valid records with 214 variables remained. With a clean, robust database, future analysis aims to identify high-risk career fields for targeted interventions or uncover potential protective factors in low-risk career fields. PMID:27483519
