Influence of crossdrafts on the performance of a biological safety cabinet. (1/1638)

A biological safety cabinet was tested to determine the effect of crossdrafts (such as those created by normal laboratory activity or ventilation) upon the ability of the cabinet to protect both experiments and investigators. A simple crossdraft, controllable from 50 to 200 feet per min (fpm; 15.24 to 60.96 m/min), was created across the face of the unit. Modifications of standardized procedures involving controlled bacterial aerosol challenges provided stringent test conditions. Results indicated that, as the crossflow velocities exceeded 100 fpm, the ability of the cabinet to protect either experiments or investigators decreased logarithmically with increasing crossdraft speed. Because 100 fpm is an airspeed easily achieved by some air conditioning and heating vents (open windows and doorways may create velocities far in excess of 200 fpm), the proper placement of a biological safety cabinet within the laboratory--away from such disruptive air currents--is essential to satisfactory cabinet performance.  (+info)

A new model rat with acute bronchiolitis and its application to research on the toxicology of inhaled particulate matter. (2/1638)

The aim of the present study was to establish a useful animal model that simulates humans sensitive to inhaled particulate matter (PM). We have developed a new rat model of acute bronchiolitis (Br) by exposing animals to NiCl2 (Ni) aerosols for five days. Three days following the Ni exposure, the animals developed signs of tachypnea, mucous hypersecretion, and bronchiolar inflammation which seemed to progress quickly during the fourth to fifth day. They recovered from lesions after four weeks in clean air. To assess the sensitivity of the Br rats to inhaled particles, two kinds of PM of respirable size were tested with doses similar to or a little higher to the recommended threshold limit values (TLVs) for the working environment in Japan. Titanium dioxide (TiO2 = Ti) was chosen as an inert and insoluble particles and vanadium pentoxide (V2O5 = V), as a representative soluble and toxic airborne material. The Br rats exposed to either Ti or V were compared the pathological changes in the lungs and the clearance of particles to those in normal control or Br rats kept in clean air. The following significant differences were observed in Br rats: 1. delayed recovery from pre-existing lesions or exacerbated inflammation, 2. reductions in deposition and clearance rate of inhaled particles with the progress of lesions. The present results suggest that Br rats are more susceptible to inhaled particles than control rats. Therefore, concentrations of particulate matter lower than the TLVs for Japan, which have no harmful effects on normal lungs, may not always be safe in the case of pre-existing lung inflammation.  (+info)

A simulation study of confounding in generalized linear models for air pollution epidemiology. (3/1638)

Confounding between the model covariates and causal variables (which may or may not be included as model covariates) is a well-known problem in regression models used in air pollution epidemiology. This problem is usually acknowledged but hardly ever investigated, especially in the context of generalized linear models. Using synthetic data sets, the present study shows how model overfit, underfit, and misfit in the presence of correlated causal variables in a Poisson regression model affect the estimated coefficients of the covariates and their confidence levels. The study also shows how this effect changes with the ranges of the covariates and the sample size. There is qualitative agreement between these study results and the corresponding expressions in the large-sample limit for the ordinary linear models. Confounding of covariates in an overfitted model (with covariates encompassing more than just the causal variables) does not bias the estimated coefficients but reduces their significance. The effect of model underfit (with some causal variables excluded as covariates) or misfit (with covariates encompassing only noncausal variables), on the other hand, leads to not only erroneous estimated coefficients, but a misguided confidence, represented by large t-values, that the estimated coefficients are significant. The results of this study indicate that models which use only one or two air quality variables, such as particulate matter [less than and equal to] 10 microm and sulfur dioxide, are probably unreliable, and that models containing several correlated and toxic or potentially toxic air quality variables should also be investigated in order to minimize the situation of model underfit or misfit.  (+info)

Indoor, outdoor, and regional summer and winter concentrations of PM10, PM2.5, SO4(2)-, H+, NH4+, NO3-, NH3, and nitrous acid in homes with and without kerosene space heaters. (4/1638)

Twenty-four-hour samples of PM10 (mass of particles with aerodynamic diameter < or = 10 microm), PM2.5, (mass of particles with aerodynamic diameter < or = 2.5 microm), particle strong acidity (H+), sulfate (SO42-), nitrate (NO3-), ammonia (NH3), nitrous acid (HONO), and sulfur dioxide were collected inside and outside of 281 homes during winter and summer periods. Measurements were also conducted during summer periods at a regional site. A total of 58 homes of nonsmokers were sampled during the summer periods and 223 homes were sampled during the winter periods. Seventy-four of the homes sampled during the winter reported the use of a kerosene heater. All homes sampled in the summer were located in southwest Virginia. All but 20 homes sampled in the winter were also located in southwest Virginia; the remainder of the homes were located in Connecticut. For homes without tobacco combustion, the regional air monitoring site (Vinton, VA) appeared to provide a reasonable estimate of concentrations of PM2.5 and SO42- during summer months outside and inside homes within the region, even when a substantial number of the homes used air conditioning. Average indoor/outdoor ratios for PM2.5 and SO42- during the summer period were 1.03 +/- 0.71 and 0.74 +/- 0.53, respectively. The indoor/outdoor mean ratio for sulfate suggests that on average approximately 75% of the fine aerosol indoors during the summer is associated with outdoor sources. Kerosene heater use during the winter months, in the absence of tobacco combustion, results in substantial increases in indoor concentrations of PM2.5, SO42-, and possibly H+, as compared to homes without kerosene heaters. During their use, we estimated that kerosene heaters added, on average, approximately 40 microg/m3 of PM2.5 and 15 microg/m3 of SO42- to background residential levels of 18 and 2 microg/m3, respectively. Results from using sulfuric acid-doped Teflon (E.I. Du Pont de Nemours & Co., Wilmington, DE) filters in homes with kerosene heaters suggest that acid particle concentrations may be substantially higher than those measured because of acid neutralization by ammonia. During the summer and winter periods indoor concentrations of ammonia are an order of magnitude higher indoors than outdoors and appear to result in lower indoor acid particle concentrations. Nitrous acid levels are higher indoors than outdoors during both winter and summer and are substantially higher in homes with unvented combustion sources.  (+info)

Biomarkers for exposure to ambient air pollution--comparison of carcinogen-DNA adduct levels with other exposure markers and markers for oxidative stress. (5/1638)

Human exposure to genotoxic compounds present in ambient air has been studied using selected biomarkers in nonsmoking Danish bus drivers and postal workers. A large interindividual variation in biomarker levels was observed. Significantly higher levels of bulky carcinogen-DNA adducts (75.42 adducts/10(8) nucleotides) and of 2-amino-apidic semialdehyde (AAS) in plasma proteins (56.7 pmol/mg protein) were observed in bus drivers working in the central part of Copenhagen, Denmark. In contrast, significantly higher levels of AAS in hemoglobin (55.8 pmol/mg protein), malondialdehyde in plasma (0. 96 nmol/ml plasma), and polycyclic aromatic hydrocarbon (PAH)-albumin adduct (3.38 fmol/ microg albumin) were observed in the suburban group. The biomarker levels in postal workers were similar to the levels in suburban bus drivers. In the combined group of bus drivers and postal workers, negative correlations were observed between bulky carcinogen-DNA adduct and PAH-albumin levels (p = 0.005), and between DNA adduct and [gamma]-glutamyl semialdehyde (GGS) in hemoglobin (p = 0.11). Highly significant correlations were found between PAH-albumin adducts and AAS in plasma (p = 0.001) and GGS in hemoglobin (p = 0.001). Significant correlations were also observed between urinary 8-oxo-7, 8-dihydro-2'-deoxyguanosine and AAS in plasma (p = 0.001) and PAH-albumin adducts (p = 0.002). The influence of the glutatione S-transferase (GST) M1 deletion on the correlation between the biomarkers was studied in the combined group. A significant negative correlation was only observed between bulky carcinogen-DNA adducts and PAH-albumin adducts (p = 0.02) and between DNA adduct and urinary mutagenic activity (p = 0.02) in the GSTM1 null group, but not in the workers who were homozygotes or heterozygotes for GSTM1. Our results indicate that some of the selected biomarkers can be used to distinguish between high and low exposure to environmental genotoxins.  (+info)

Short-term associations between outdoor air pollution and visits to accident and emergency departments in London for respiratory complaints. (6/1638)

Many epidemiological studies have shown positive short-term associations between health and current levels of outdoor air pollution. The aim of this study was to investigate the association between air pollution and the number of visits to accident and emergency (A&E) departments in London for respiratory complaints. A&E visits include the less severe cases of acute respiratory disease and are unrestricted by bed availability. Daily counts of visits to 12 London A&E departments for asthma, other respiratory complaints, and both combined for a number of age groups were constructed from manual registers of visits for the period 1992-1994. A Poisson regression allowing for seasonal patterns, meteorological conditions and influenza epidemics was used to assess the associations between the number of visits and six pollutants: nitrogen dioxide, ozone, sulphur dioxide, carbon monoxide, and particles measured as black smoke (BS) and particles with a median aerodynamic diameter of <10 microm (PM10). After making an allowance for the multiplicity of tests, there remained strong associations between visits for all respiratory complaints and increases in SO2: a 2.8% (95% confidence interval (CI) 0.7-4.9) increase in the number of visits for a 18 microg x (-3) increase (10th-90th percentile range) and a 3.0% (95% CI 0.8-5.2) increase for a 31 microg x m(-3) increase in PM10. There were also significant associations between visits for asthma and SO2, NO2 and PM10. No significant associations between O3 and any of the respiratory complaints investigated were found. Because of the strong correlation between pollutants, it was difficult to identify a single pollutant responsible for the associations found in the analyses. This study suggests that the levels of air pollution currently experienced in London are linked to short-term increases in the number of people visiting accident and emergency departments with respiratory complaints.  (+info)

Increased exhaled nitric oxide on days with high outdoor air pollution is of endogenous origin. (7/1638)

The aim of this study was to assess the effect of outdoor air pollution on exhaled levels of endogenously released nitric oxide. To exclude bias from exogenous NO in the recovered exhaled air (residual NO or NO in dead volume) an experimental design was used that sampled NO of endogenous origin only. The validity of the presented experimental design was established in experiments where subjects were exposed to high levels of exogenous NO (cigarette smoke or 480 microg x m(-3) synthetic NO). Subsequent 1 min breathing and a final inhalation of NO-free air proved to be sufficient to attain pre-exposure values. Using the presented method detecting only endogenous NO in exhaled air, 18 subjects were sampled on 4 separate days with different levels of outdoor air pollution (read as an ambient NO level of 4, 30, 138 and 246 microg x m(-3)). On the 2 days with highest outdoor air pollution, exhaled NO was significantly (p<0.001) increased (67-78%) above the mean baseline value assessed on 4 days with virtually no outdoor air pollution. In conclusion, the level of endogenous nitric oxide in exhaled air is increased on days with high outdoor air pollution. The physiological implications of this findings need to be investigated further.  (+info)

Air pollution, pollens, and daily admissions for asthma in London 1987-92. (8/1638)

BACKGROUND: A study was undertaken to investigate the relationship between daily hospital admissions for asthma and air pollution in London in 1987-92 and the possible confounding and modifying effects of airborne pollen. METHODS: For all ages together and the age groups 0-14, 15-64 and 65+ years, Poisson regression was used to estimate the relative risk of daily asthma admissions associated with changes in ozone, sulphur dioxide, nitrogen dioxide and particles (black smoke), controlling for time trends, seasonal factors, calendar effects, influenza epidemics, temperature, humidity, and autocorrelation. Independent effects of individual pollutants and interactions with aeroallergens were explored using two pollutant models and models including pollen counts (grass, oak and birch). RESULTS: In all-year analyses ozone was significantly associated with admissions in the 15-64 age group (10 ppb eight hour ozone, 3.93% increase), nitrogen dioxide in the 0-14 and 65+ age groups (10 ppb 24 hour nitrogen dioxide, 1.25% and 2.96%, respectively), sulphur dioxide in the 0-14 age group (10 micrograms/m3 24 hour sulphur dioxide, 1.64%), and black smoke in the 65% age group (10 micrograms/m3 black smoke, 5.60%). Significant seasonal differences were observed for ozone in the 0-14 and 15-64 age groups, and in the 0-14 age group there were negative associations with ozone in the cool season. In general, cumulative lags of up to three days tended to show stronger and more significant effects than single day lags. In two-pollutant models these associations were most robust for ozone and least for nitrogen dioxide. There was no evidence that the associations with air pollutants were due to confounding by any of the pollens, and little evidence of an interaction between pollens and pollution except for synergism of sulphur dioxide and grass pollen in children (p < 0.01). CONCLUSIONS: Ozone, sulphur dioxide, nitrogen dioxide, and particles were all found to have significant associations with daily hospital admissions for asthma, but there was a lack of consistency across the age groups in the specific pollutant. These associations were not explained by confounding by airborne pollens nor was there convincing evidence that the effects of air pollutants and airborne pollens interact in causing hospital admissions for asthma.  (+info)

The Air Pollution Control Act of 1955 (Pub.L. 84-159, ch. 360, 69 Stat. 322) was the first Clean Air Act (United States) enacted by Congress to address the national environmental problem of air pollution on July 14, 1955. This was an act to provide research and technical assistance relating to air pollution control. The act left states principally in charge of prevention and control of air pollution at the source. The act declared that air pollution was a danger to public health and welfare, but preserved the primary responsibilities and rights of the states and local government in controlling air pollution. The act put the federal government in a purely informational role, authorizing the United States Surgeon General to conduct research, investigate, and pass out information relating to air pollution and the prevention and abatement thereof. Therefore, The Air Pollution Control Act contained no provisions for the federal government to actively combat air pollution by punishing ...
BACKGROUND: Exposure to ambient air pollution is suspected to cause cognitive effects, but a prospective cohort is needed to study exposure to air pollution at the home address and the incidence of dementia.. OBJECTIVES: We aimed to assess the association between long-term exposure to traffic-related air pollution and dementia incidence in a major city in northern Sweden.. METHODS: Data on dementia incidence over a 15-year period were obtained from the longitudinal Betula study. Traffic air pollution exposure was assessed with a Land Use Regression Model with a spatial resolution of 50 m x 50 m. Annual mean nitrogen oxide levels at the residential address of the participants at baseline (the start of follow-up) was used as a marker for long-term exposure to air pollution.. RESULTS: Out of 1806 participants at baseline, 191 were diagnosed with Alzheimers disease during follow-up, and 111 were diagnosed with vascular dementia. Participants in the highest exposure group were more likely to be ...

Our world is a pretty dirty place for most of us and it hurts health of many people. A new World Health Organization (WHO) air quality model confirms that 92% of the worlds population lives in places where air quality levels exceed WHO limits. 92% of the worlds population exposed to unsafe levels of air pollution article from Science Daily tells that some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air pollution can be just as deadly. In 2012, an estimated 6.5 million deaths (11.6% of all global deaths) were associated with indoor and outdoor air pollution together.. The new WHO model shows countries where the air pollution danger spots are: This WHO heat map shows the highest (red) and lowest (green) levels of air pollution worldwide.. ...
Background: Out-of-hospital cardiac arrest (OHCA) remains a major public health issue. Several studies have found that an increased level of ambient particulate matter (PM) smaller than 2.5 microns (PM2.5) is associated with an increased risk of OHCA. We investigated the relationship between air pollution levels and the incidence of OHCA in Perth, Western Australia.Methods: We linked St John Ambulance OHCA data of presumed cardiac aetiology with Perth air pollution data from seven monitors which recorded hourly levels of PM smaller than 2.5 and 10 microns (PM2.5/PM10), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O3). We used a case-crossover design to estimate the strength of association between ambient air pollution levels and risk of OHCA.Methods: We linked St John Ambulance OHCA data of presumed cardiac aetiology with Perth air pollution data from seven monitors which recorded hourly levels of PM smaller than 2.5 and 10 microns (PM2.5/PM10), carbon monoxide ...
According to a new research, air pollution has reached a critical level in India and has merged as the fifth largest cause of death in the country.. A study in the medical journal Lancet showed that 6.2 lakh million premature deaths, which is an increase of six times since 2000. The country specific data on Global Burden of Diseases (GBD) report showed that air pollution has emerged as one of the largest causes of for deaths in 2010 in the country. An analysis by Health Effects Institute, which is based in Washington, showed that indoor air pollution and direct and indirect tobacco smoking caused one million deaths each year while 620,000 people died because of outdoor air pollution in 2010.. Aaron Cohen, the head of the expert group on air pollution for the analysis also said that air pollution caused 20 per cent of lung cancer and 6 per cent of high blood pressure deaths in the country. The data pointed out that the India does not have any standard for indoor air pollution and policy makers ...

BACKGROUND: Industrialization has been linked to the etiology of inflammatory bowel disease (IBD). AIM: We investigated the association between air pollution exposure and IBD. METHODS: The European Prospective Investigation into Cancer and Nutrition cohort was used to identify cases with Crohns disease (CD) (n = 38) and ulcerative colitis (UC) (n = 104) and controls (n = 568) from Denmark, France, the Netherlands, and the UK, matched for center, gender, age, and date of recruitment. Air pollution data were obtained from the European Study of Cohorts for Air Pollution Effects. Residential exposure was assessed with land-use regression models for particulate matter with diameters of |10 μm (PM10), |2.5 μm (PM2.5), and between 2.5 and 10 μm (PMcoarse), soot (PM2.5 absorbance), nitrogen oxides, and two traffic indicators. Conditional logistic regression analyses were performed to calculate odds ratios (ORs) with 95 % confidence intervals (CIs). RESULTS: Although air pollution was not significantly
Air pollution and tuberculosis (TB) are public health threats of global proportion, with one-third f people worldwide infected with TB and nearly 90% of the global population living in areas where pollution exceeds safe standards set by the World Health Organization. Children in Viet Nam are exposed to concerning levels of secondhand smoke, cooking smoke, and traffic emissions, yet little is known about the effects of these pollutants on childhood TB. We therefore propose to study the clinical and immunologic effects of air pollutants on childhood TB in Viet Nam. Our overall hypothesis is that air pollution exposures will be associated with increased risk for TB infection and altered immunologic responses to Mycobacterium tuberculosis (Mtb). To test this hypothesis, we will first develop and validate a questionnaire and air pollution models that accurately predict air pollution exposures in children at risk for TB living in Viet Nam (Aim 1). I Aim 2, to evaluate air pollution exposures as risk ...

Background and aims: Air pollution is one of the health problems worldwide. Previous epidemiological studies have investigated the impacts of air pollution on respiratory and cardiovascular diseases. The aim of this study was to determine the associations between air pollution levels and different health indicators among world countries. Methods: This ecological study was performed in 2013 by using dataset of World Health Organization (WHO). The main variable in our study was air pollution index. The data including Maternal Mortality Rate (MMR) (per 100000 live births), Life Expectancy at birth (LE), preterm birth rate (per 1000 live births) and Non-Communicable Diseases (NCD) death rate (per 100000 populations) from 91 countries were extracted. Pearson correlation coefficient was used to assess the linear correlation between air pollution and investigated indexes using Stata 11. Results: MMR (r=0.36, P=0.001) and NCD death rate (r=0.31, P=0.002) were positively associated with air pollution level. The
BACKGROUND: Long-term exposure to air pollution is hypothesized to elevate arterial blood pressure (BP). The existing evidence is scarce and country-specific. OBJECTIVES: We investigated the cross-sectional association of long-term traffic-related air pollution with BP and prevalent hypertension in European populations. METHODS: Fifteen population-based cohorts, participating in the European Study of Cohorts for Air Pollution Effects (ESCAPE), were analysed. Residential exposure to particulate matter and nitrogen oxides was modelled with land use regression using a uniform protocol. Traffic exposure was assessed with traffic indicator variables. We analysed systolic and diastolic BP in participants medicated and non-medicated with BP lowering medication (BPLM) separately, adjusting for personal and area-level risk factors and environmental noise. Prevalent hypertension was defined as ≥ 140 mmHg systolic, or ≥ 90 mmHg diastolic BP, or intake of BPLM. We combined cohort-specific results using ...
Health effects of ambient air pollution were studied in three groups of schoolchildren living in areas (suburban, urban and urban-traffic) with different air pollution levels in EskiAYehir, Turkey. This study involved 1,880 students aged between 9 and 13 years from 16 public primary schools. This two-season study was conducted from January 2008 through March 2009. Symptoms of asthma, rhinitis and eczema were determined by the International Study of Asthma and Allergies in Childhood questionnaire in 2008. Two lung function tests were performed by each child for summer and winter seasons with simultaneous ambient air measurements of ozone (O-3), nitrogen dioxide (NO2) and sulfur dioxide (SO2) by passive sampling. Effects of air pollution on impaired lung function and symptoms in schoolchildren were estimated by multivariate logistic regression analyses. Girls with impaired lung function (only for the summer season evaluation) were more observed in suburban and urban areas when compared to ...
Major cities in India are currently experiencing severe levels of air pollution. Some of the most common health effects of air pollution include irritation of eyes, throat and lungs. For people with existing respiratory conditions such as asthma or bronchitis, breathing in air pollution can make these conditions worse. New Zealanders in areas affected by the air pollution are advised to monitor pollution readings, such as those provided by the Air Quality Index website. If you have concerns about the level of pollution, we recommend remaining indoors as much as possible, with doors and windows closed, and refraining from strenuous activity when outdoors. We also recommend seeking medical advice about appropriate precautions. New Zealanders are advised to follow the advice of local authorities at all times.. The following sites may give further advice and data regarding pollution levels:. ...
Famously, the use of caged birds to alert miners to the invisible dangers of gases such as carbon monoxide gave rise to the cautionary metaphor canary in a coal mine.. But other than the fact that exposure to toxic gases in a confined space kills caged birds before affecting humans - providing a timely warning to miners - what do we know about the effects of air pollution on birds?. Not as much as youd think, according to researchers from the University of Wisconsin-Madison.. We know a lot about air pollutions effects on human health, and we know a lot about the impacts of air pollution across ecosystems, explains Tracey Holloway, a professor in UW-Madisons Nelson Institute for Environmental Studies. We were surprised to discover how little we know about how air pollution affects birds.. Writing Aug. 11 in the journal Environmental Research Letters, Holloway, an expert on air quality, and her former graduate student Olivia Sanderfoot, sort through nearly 70 years of the scientific ...
Concentrated animal feeding operations (CAFOs), also known as factory farms, emit large amounts of air pollution, including methane, ammonia, nitrous oxide, volatile organic compounds, and particulate matter. Yet Oregon has no air pollution control program to monitor and reduce factory farm pollution. While the U.S. Environmental Protection Agency (EPA) has long acknowledged the problem of factory farm air pollution, EPA fails to regulate the industry. In the face of federal inaction, states including Minnesota, California, and Idaho have adopted laws to reduce air pollution from factory farms. To date, Oregon has not adopted regulations to control air pollution from factory farms.. The Legislature Must Act - Pass SB 197 ...
With an increased awareness of health and economic costs associated with air pollution exposures - from direct health impacts (e.g. 3.1 million deaths per year worldwide), to repercussions on workforce productivity (e.g. projected 82 million lost workdays in Europe in 2025), and difficulties in attracting qualified workforce and tourists in highly polluted cities - there is a real need to tackle air pollution problems in cities more efficiently.. The AirMAP method combines big data from mobile phones and vehicle fleet GPS tracking with air pollution maps to estimate exposures to air pollution in the population. With the proposed approach, we are thus able to assess exposures accounting for peoples movement in space and time, rather than with the usual static approach whereby people are assumed to spend their whole lives at home. This novel approach can enable policy makers to target much more efficiently and cost-effectively air pollution reductions efforts to protect people from air ...
The effects of air pollution on the respiratory and cardiovascular systems, and the resulting impacts on public health, have been widely studied. However, little is known about the effect of air pollution on the occurrence of hemorrhagic fever with renal syndrome (HFRS), a rodent-borne infectious disease. In this study, we evaluated the correlation between air pollution and HFRS incidence from 2001 to 2010, and estimated the significance of the correlation under the effect of climate variables. We obtained data regarding HFRS, particulate matter smaller than 10 μm (PM10) as an index of air pollution, and climate variables including temperature, humidity, and precipitation from the national database of South Korea. Poisson regression models were established to predict the number of HFRS cases using air pollution and climate variables with different time lags. We then compared the ability of the climate model and the combined climate and air pollution model to predict the occurrence of HFRS. The
Air pollution, aside from cigarette smoke, may not be an obvious risk factor for birth defects particularly in developed countries.. However, according to the results of a large European study, exposure to air pollution throughout pregnancy significantly increases the risk of having a low birth weight baby.. Low birth weight (under 2.5 kg) in full term infants has been associated with increased risk of mortality and morbidity in comparison to healthy birthweight infants. It also increases the likelihood of experiencing respiratory problems during childhood and later in life.. With high prevalence rates of respiratory conditions such as asthma worldwide, exposure to air pollution appears to one of the most important heath factors to address throughout pregnancy.. How Air Pollution Affects the Health of a Pregnancy Researchers compiled data from the European Study of Cohorts for Air Pollution Effects (ESCAPE) to analyse 14 cohort studies conducted throughout Europe involving over 74,000 women who ...

If youre planning to exercise, which is really important, maybe take into account what the air quality alert is for that day, and if its going to be a high pollution day, dont exercise outside, she says. Exercise inside or rearrange your schedule to exercise at the time of day when air pollution is lower or in a park thats not close to a busy roadway. If youre at home and its a hot day out, rather than opening the windows, turn on the air conditioning to keep pollution out ...
What do smog, acid rain, carbon monoxide, fossil fuel exhausts, and tropospheric ozone have in common? They are all examples of air pollution. Air pollution is not new. As far back as the 13 th century, people started complaining about coal dust and soot in the air over London, England. Since the beginning of the industrial revolution in the late 1700s, we have been changing the Earths atmosphere and its chemistry. As industry spread across the globe, so did air pollution. Air pollution has many effects. In addition to being ugly, it can cause illness and even death. It damages buildings, crops, and wildlife. The worst air pollution happened in London when dense smog (a mixture of smoke and fog) formed in December of 1952 and lasted until March of 1953. 4,000 people died in one week. 8,000 more died within six months.. Air pollution is made up of solid particles and chemicals. Natural processes impacting the atmosphere include volcanoes, biological decay, and dust storms. Plants, trees, and ...
This study was the largest human-controlled air pollution exposure protocol yet completed (274 total exposures).9,11 Our well-coordinated design and uniform methods between 2 sites provided us the unique ability to compare CV responses with air pollution from different locations.. It is unclear why we did not replicate previous findings of brachial artery vasoconstriction after CAP plus ozone exposures.9 We either failed to identify its occurrence, or this vascular territory behaved in a discordant manner between experiments. It is also uncertain why exposures elicited a greater effect on diastolic rather than systolic BP. Additional studies are required, but perhaps the underlying hemodynamic changes responsible reflected a predominant vasoconstriction without changes in cardiac output or arterial compliance (as suggested by the results in Table 6).. We also limited blood biomarker interpretation to the Toronto results because this was where we could account for any filtered air (placebo) ...
Public concern regarding air pollution has increased rapidly in recent years. Because air pollution may present special problems in the pediatric age group, available information on the effects of various air pollutants on children has been reviewed with the purpose of: (1) defining the potential ill effects of air pollution in this age group, (2) making information regarding these effects readily accessible to pediatricians, and (3) delineating further areas of study which may be necessary to safeguard child health from this environmental hazard.. Three general conclusions became apparent to the Committee after reviewing more than 100 publications from the world literature dealing specifically with the health effects of air pollution on children * The first is that children as a group may serve to delineate more clearly the effect of air pollution on health. They (1) spend most of their lives and attend school in limited geographical areas where air quality and meteorological effects can be ...
Reviews find a likely adverse effect of air pollution on perinatal outcomes, but variation of findings hinders the ability to incorporate the research into policy. The International Collaboration on Air Pollution and Pregnancy Outcomes (ICAPPO) was formed to better understand relationships between air pollution and adverse birth outcomes through standardized parallel analyses in datasets from different countries. A planning group with 10 members from 6 countries was formed to coordinate the project. Collaboration participants have datasets with air pollution values and birth outcomes. Eighteen research groups with data for approximately 20 locations in Asia, Australia, Europe, North America, and South America are participating, with most participating in an initial pilot study. Datasets generally cover the 1990s. Number of births is generally in the hundreds of thousands, but ranges from around 1,000 to about one million. Almost all participants have some measure of particulate matter, and most have
Allergic rhinitis (AR) is impacted by allergens and air pollution but interactions between air pollution, sleep and allergic diseases are insufficiently understood. POLLAR (Impact of air POLLution on sleep, Asthma and Rhinitis) is a project of the European Institute of Innovation and Technology (EIT Health). It will use a freely-existing application for AR monitoring that has been tested in 23 countries (the Allergy Diary, iOS and Android, 17,000 users, TLR8). The Allergy Diary will be combined with a new tool allowing queries on allergen, pollen (TLR2), sleep quality and disorders (TRL2) as well as existing longitudinal and geolocalized pollution data. Machine learning will be used to assess the relationship between air pollution, sleep and AR comparing polluted and non-polluted areas in 6 EU countries. Data generated in 2018 will be confirmed in 2019 and extended by the individual prospective assessment of pollution (portable sensor, TLR7) in AR. Sleep apnea patients will be used as a demonstrator of
Air pollution is not good for the health. Now there is more reason to be concerned, as air pollution can affect antibiotics effectiveness.
Asthma prevalence has steadily increased in the United States since the early 1980s; currently more than 20 million people are diagnosed with asthma, including 9 million children. Asthma can be caused by many factors, including pollen, dust, tobacco smoke, and other allergens. Research has shown that even short-term increases in daily levels of air pollution can trigger an increase in asthma symptoms in some individuals. More research is needed to determine how short-term increases in air pollution affect the severity of asthma later in life. The Environmental Protection Agency (EPA) has constructed research monitoring stations, known as Supersites, to advance the understanding of the effect of airborne pollutants on the health of individuals. Data collected from the Supersites provide important information regarding air pollution and air quality levels. This study will use air pollution measurements obtained from the Fresno, California Supersite to monitor participants exposure to air ...
The Phase I.B Report of the Particle Epidemiology Evaluation Project. The Health Effects Institute began the Particle Epidemiology Evaluation Project in 1994 to evaluate the emerging epidemiologic evidence of a relation between particulate air pollution and daily mortality. In Phase I.B, Drs. Jonathan M. Samet and Scott L. Zeger and their colleagues at the Johns Hopkins University School of Hygiene and Public Health (1) compared approaches for controlling the effects of weather variables when analyzing the connection between air pollution and daily mortality, primarily focusing on Synoptic Weather Categories, an approach newly proposed by Dr. Laurence S. Kalkstein of the University of Delaware; and (2) evaluated the association between particulate air pollution and daily mortality in the Philadelphia metropolitan area using statistical models that included data for five pollutants regulated under the Clean Air Act Amendments of 1990 (referred to as criteria pollutants).

As cold season inversion has shrouded a number of Iranian cities in smog, President Hassan Rouhani unveiled plans on Wednesday. for urgent, short-term measures to tackle severe pollution.. Speaking at a weekly session of the Cabinet, President Rouhani said necessary decisions have been made to deal with the pressing problem of air pollution.. Public concern about the pollution is reasonable and just, the president contended, stressing the need for continuous efforts to allay concerns on the issue.. Although tackling the air pollution is not possible in a short-term period, the administration will make whatever decision necessary to combat the problem, Rouhani added.. In recent weeks, cold temperatures and stagnant air in a number of big Iranian cities, including capital Tehran, have put the air pollution index as much as 7 times the levels recommended by the World Health Organization.. Severe air pollution prompted authorities last week to shut down schools for three days in and around the ...
Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. Ever since the beginning of the Industrial Revolution in the United States, America has had much trouble with environmental issues, air pollution in particular. According to a 2009 report, around 60 percent of Americans live in areas where air pollution has reached unhealthy levels that can make people sick. Pollution in the United States has plummeted in the recent decade, with pollutants such as nitrogen dioxide decreasing despite the fact the number of vehicles on the road isnt. This is due to better regulations, economic shifts, and technological innovations. With respect to nitrogen dioxide, NASA reported a 32% decrease in New York City and a 42% decrease in Atlanta between the periods of 2005-2007 and 2009-2011. Air pollution can cause a variety of health problems including, ...
We simulated commuter routes and long-term exposure to traffic-related air pollution during commute in a representative population sample in Basel (Switzerland), and evaluated three air pollution models with different spatial resolution for estimating commute exposures to nitrogen dioxide (NO2) as a marker of long-term exposure to traffic-related air pollution. Our approach includes spatially and temporally resolved data on actual commuter routes, travel modes and three air pollution models. Annual mean NO2 commuter exposures were similar between models. However, we found more within-city and within-subject variability in annual mean (±SD) NO2 commuter exposure with a high resolution dispersion model (40 ± 7 µg m−3, range: 21-61) than with a dispersion model with a lower resolution (39 ± 5 µg m−3; range: 24-51), and a land use regression model (41 ± 5 µg m−3; range: 24-54). Highest median cumulative exposures were calculated along motorized transport and bicycle routes, and the lowest for
The human health effects of exposure to tropospheric outdoor air pollutants, which include both particulate matter and gaseous contaminants, have gained prominence as a global public health concern. Indeed, the most recent Global Burden of Disease (GBD) report lists outdoor air pollution as a leading cause of death and lost disability-adjusted life years, accounting for an estimated ,3 million premature deaths per year globally [1, 2], as well as similarly large numbers of deaths associated with indoor air pollution exposures (e.g. biomass and coal burning smoke). However, outdoor air pollution exposures and trends are quite disparate in different parts of the globe: the principal community air pollutants monitored for regulatory purposes, including carbon monoxide, nitrogen dioxide (NO2), sulfur dioxide, particulate matter (PM) and ozone, have generally (but not universally) shown declining concentrations in the developed nations in recent years, while in the low- and middle-income countries ...
Exposure to air pollution can worsen blood sugar levels, cholesterol and other risk factors for heart disease, particularly in people with diabetes, according to a new study, The Association between Air Pollution Exposure and Glucose and Lipid Levels, published in the Endocrine Societys Journal of Clinical Endocrinology & Metabolism. While air pollution is linked with relatively small changes in cardiometabolic risk factors, the continuous nature of exposure and the number of people affected gives us cause for concern, said the studys senior author, Victor Novack, MD, PhD, of BGU and Soroka University Medical Center. Even small changes in glucose levels and glycemic control can contribute to increased risk of cardiovascular disease.. The population-based retrospective cohort study examined the effects of air pollution exposure on 73,117 adults living in southern Israel, where levels of particulate matter can escalate due to its location in the global dust belt. To assess air pollution, ...
Heavy industry emits many potentially hazardous pollutants into the air which can affect health. However, the effects of air pollution from heavy industry on lung function and respiratory symptoms have been investigated scarcely. Our aim was to investigate the associations of long-term air pollution from heavy industry with lung function and respiratory symptoms in school children. A cross-sectional lung function study was conducted among school children (7-13 years) in the vicinity of an area with heavy industry. Lung function measurements were conducted during school hours. Parents of the children were asked to complete a questionnaire about the health of their children. A dispersion model was used to characterize the additional individual-level exposures to air pollutants from the industry in the area. Associations between PM2.5 and NOX exposure with lung function and presence of respiratory symptoms were investigated by linear and/or logistic regression analysis. Participation in the lung function
Long term exposure to low-level air pollution may increase the risk of severe chronic obstructive pulmonary disease, according to researcher s in Denmark. While acute exposure of several days to high level air pollution was known to be a risk factor for exacerbation in pre-existing COPD, until now there had been no studies linking long-term air pollution exposure to the development or progression of the disease.
The African Development Bank is focusing more strongly on air pollution. As part of the banks 10-year strategy to facilitate Africas gradual transition to green growth, the bank has awarded Ramboll a contract for transport emission mapping and monitoring as well as capacity building in five cities.. Although indoor air pollution is the greatest problem, vehicle emissions are also steadily climbing, driven by urban sprawl, rapid motorisation and low levels of institutional capacity to manage traffic and its impacts. The United Nations Environment Programme (UNEP) estimates that vehicle emissions account for 90% of urban air pollution in developing countries.. The main objective of the African Development Bank project is to advise city authorities and policy-makers on efficient and accurate methods for collecting, storing and analysing data as well as mapping air pollution levels in cities and, to identify options for financing low-emission transport technologies.

NGO News Desk :: Outdoor air pollution has become the fifth largest killer in India after high blood pressure, indoor air pollution, tobacco smoking, and poor nutrition - says a new set of findings of the Global Burden of Disease report. The India and South Asia-specific findings were officially released here today at a Dialogue Workshop jointly organised by Centre for Science and Environment (CSE), Indian Council of Medical Research and the US-based Health Effects Institute.. The Global Burden of Disease (GBD) report is a world-wide initiative involving the World Health Organization which tracks deaths and illnesses from all causes across the world every 10 years. The new findings were released by Aaron Cohen, principal epidemiologist of the Health Effects Institute and co-chair of the GBD Ambient Air Pollution Expert Group.. The report says that about 620,000 premature deaths occur in India from air pollution-related diseases. GBD has ranked air pollution as one of the top 10 killers in the ...

Air pollution health risks: A recent World Health Organization report showed that over 100,000 children under five in India died due to indoor and outdoor air pollution in 2016. One important threat to child health posed by household air pollution is pneumonia, which is the leading infectious cause of death among children under five in the country and the world.
A Unicef report states that toxic air severely affects childrens brain development and may cause a permanent damage to their brains. The report mentions that toxic air can also lead to anxiety disorder and may affect IQ level and memory pattern in kids. Severe air pollution can also lead to other neurological disorders like Attention Deficit Hyperactivity Disorder (ADHD). The findings come at a time when India, particularly in the north, is facing a serious crisis due to rising levels of pollution. Last month, Delhi schools had to be shut temporarily to reduce childrens exposure to pollutants that had enveloped the capital. The air pollution level has been consistently 10 points above the safe zone. The Unicef report also said that South Asia had the largest proportion of babies living in areas where air pollution is at least six times higher than international limits (10 micrograms per cubic metre).. ...
During the last week of September prominent figures from government, finance, business, and civil society came together in New York for the United Nations Climate Summit 2014 to catalyse meaningful action to address climate change. Many climate-related actions may bring co-benefits for the reduction of air pollution both locally and globally. However, this is not a given: it is crucial that such policies are carefully designed to ensure they do not shift the problem from climate change to air pollution. That could pose implementation problems for States wanting, on the one hand, to comply with their climate-related obligations and, on the other hand, to comply with their air pollution reduction obligations under the UNECE Convention on Long-range Transboundary Air Pollution (Air Convention) and its protocols. Earlier this year the World Health Organization (WHO) estimated that in 2012 almost 600,000 deaths in the European region were attributable to air pollution, with the vast majority ...

A study suggested that air pollution can increase mortality from coronavirus and add to the ever-increasing number of deaths during this pandemic.
A third of the worlds population use plant-based solid fuels such as wood or charcoal, or coal, to cook, heat, and light their homes, primarily in Asia and Africa. These smoky, dirty fuels are often used in an open fire or simple stove, resulting in high levels of household air pollution in poorly ventilated homes.. Studies in India have found that in some areas, household air pollution is so high that it actually increases outdoor (ambient) air pollution - leading to pollution levels more than three times higher than a typical London street, and well above WHO-recommended safety levels.. The Commission, which was led by Professor Stephen Gordon, from the Liverpool School of Tropical Medicine, UK, and Professor William Martin, from The Ohio State University, USA, examines evidence for the effects of household air pollution on health. They conclude that an estimated 600-800 million families worldwide are at increased risk of illnesses such as respiratory tract infections, pneumonia, COPD, ...
Cant Do A Surgical Strike On Air Pollution, Says Minister Harsh Vardhan | Video | Union environment minister Harsh Vardhan today rebutted the allegations of the Delhi government that the Centre had been aloof about the smog that has been choking the national capital, saying one cannot launch surgical strikes against pollution. Prime Minister Narendra Modi, he said, has been monitoring the situation but insisted that a solution has to be found by the states.
Over half the worlds population lives without the protection of proper air quality standards Millions of people die prematurely every year from diseases and cancer caused by air pollution. The first line of defence against this carnage is ambient air quality standards. Yet, according to researchers from McGill University, over half of the worlds population lives without the protection of adequate air quality standards. Air pollution varies greatly in different parts of the world. But what about the primary weapons against it? To find answers, researchers from McGill University set out to investigate global air quality standards in a study published in the Bulletin of the World Health Organization. The researchers focused on air pollution called PM2.5 - responsible for an estimated 4.2 million premature deaths every year globally. This includes over a million deaths in China, over half a million in India, almost 200,000 in Europe, and over 50,000 in the United States.
Background: Urban air pollution can trigger asthma exacerbations, but the effects of long-term exposure to traffic-related air pollution on lung function, or onset of airway disease and allergic sensitization in children is less clear. Methods: All 2107 children aged 9-14 from 40 schools in Rome in 2000-2001 were included in a cross-sectional survey. Respiratory symptoms were assessed on 1760 children by parental questionnaires (response rate=83.5%). Allergic sensitization was measured by skin prick tests and lung function was measured by spirometry on 1359 children (77.2%). Three indicators of traffic-related air pollution exposure were assessed, i.e. self-reported traffic outside the childs home, the measured distance between the childs home and busy roads, and the residential nitrogen dioxide (NO2) levels estimated by a land-use regression model (R2=0.69). Results: We found a strong association between estimated NO2 exposure per 10 μg/m3 and lung function, especially expiratory flows, in ...
Smog damages international executive recruitment. Back to China… according to the American Chamber of Commerce in Beijing, Chinas infamous smog is putting top foreign executives off working in the country, highlighting how air pollution is damaging international recruitment. And in the EU, the European Environment Bureau claims air pollution reductions proposed by member states are regrettably low, and that member states have been given too long to meet them.. Some London air pollution levels are double the legal limit. London Liberal Democrat politicians claim existing measures to protect school children from air pollution are not working, after surveying the capitals 935 schools that sit within 150m of a busy road. Another piece of research reveals air pollution levels are reaching almost double the legal limit in some areas of Highgate, London. And it appears the weirdly warm spring weather might trigger smog alerts in our biggest cities.. Bringing more fresh air indoors. Poor air ...
Abstract Background: Globally, indoor air pollution from various forms of pollutants is an increasing problem. The most common form of indoor air pollution is that caused by inefficient burning of solid and fossil fuels like wood, charcoal and kerosene in indoor environments. Indoor air pollution is therefore a significant problem particularly in sub-Saharan Africa (SSA) including Uganda where use of such solid fuels is most common. There is however little attention drawn to understanding the problem specifically in Uganda to come up with tailor-made solutions. Objectives: To assess risk factors for indoor air pollution exposure in households in Bulamu ward, Kasangati town council, Wakiso district so as to provide information that could be used to make proper decisions and design measures to reduce indoor air pollution. Methodology: A cross sectional study was carried out among 96 households in Bulamu ward, Kasangati town council, Wakiso district. From the 5 villages within the ward, 1 was ...
Health impact assessments usually apply air pollution effect estimates derived from a study in one population (the evidentiary population), to estimate impacts in another (the target population). Such assessments assume that the effect estimates in the evidentiary population are transferable, or generalisable, to the target population. The validity of this assumption implicitly requires that the two populations be similar with regard to factors that influence the magnitude of the effect estimates, such as structure of the morbidity, basic health status, or composition of the air pollution mix. Recent analyses have begun to explore how such factors may explain the variation in air pollution effect estimates observed among locations in Europe and the United States.2,18-20 They suggest the presence of significant and real heterogeneity in location specific estimates that may need to be taken into account in health impact assessments. However, at present knowledge about effect modifiers is quite ...

Woolcock Institute of Medical Research, Centre for Air Quality and Health Research and Evaluation (CAR) Review of the health impacts of emission sources, types and levels of particulate matter air pollution
Clean air is considered as one of the basic requirements for human being. Pollution-related diseases due to air pollution continue to rise at an alarming rate and affect peoples quality of life. Air pollution also adversely affects welfare inequality. Air pollution as a significant risk factor affects health and sense of subjective well-being (SWB). In this study, the effect of air pollution on subjective well-being (life satisfaction, happiness, and optimism) is investigated. Relationship between well-being and air quality is a fundamental issue to design public policies. Hence, the studies about the link are of grooving interest in the literature. The results show that air pollutants have an effect on subjective well-being. The link between life satisfaction and happiness is very strong. Optimism is also positively correlated with life satisfaction and happiness. Good air quality and optimism make people happier. Air quality is likely to have an effect on peoples sense of life satisfaction,
German researchers report more evidence of another risk factor for developing type II diabetes: traffic related air pollution. After following a group of middle-aged women for 16 years, the authors find that exposure to high levels of air pollution is associated with an increased risk of type II diabetes in later years.... The study is one of the first to follow participants over many years in order to look at whether traffic-related air pollution might be linked to the risk of developing diabetes later in life. It agrees with a handful of prior human and animal studies that have suggested a link between the two. As the world becomes increasingly urban and megacities emerge, traffic-related air pollution is an increasingly serious problem. It poses environmental, ecological and human health risks, including well-documented respiratory illnesses such as asthma and lung cancer ...
Home National Climate Change, Unplanned Urbanization And Air Pollution Can Fail Us In Beating NCDs SocialPost Bureau Non-communicable diseases (NCDs), mostly cardiovascular diseases, cancers, diabetes, and lung diseases, account for over two-thirds of world's deaths each year. Of these, the lung diseases are the least recognized, said Dr Dean Schraufnagel, Executive Director, Forum of International Respiratory Societies (FIRS), who was among the key experts at the 2nd Global NCD Alliance Forum in Sharjah, United Arab Emirates (UAE).
From January to March, ambient air pollution in the capital exceeded the World Health Organizations standards on 78 days, the study by the Hanoi-based Green Innovation and Development Center (GreenID) at the Vietnam Union of Science and Technology Associations found.. Ambient air pollution is measured by the concentration of particulate matter 2.5 (PM2.5), a fraction of the width of a human hair which is released from vehicles, industry and natural sources like dust.. The PM2.5 concentration in Hanoi on February 15 was 234 μg/m3, the study found. The WHO limit is 25 μg/m3.. Nguy Thi Khanh, director of the center, told a conference on Wednesday that pollution had hit levels that were very harmful to health on multiple occasions.. The study said air quality in Ho Chi Minh City was better than in Hanoi, but the ambient air pollution also exceeded the WHO limit on 78 days.. The Real-Time Air Quality Index on forecasts that pollution levels in Hanoi will hit very unhealthy levels ...
SEOUL, March 23 (Korea Bizwire) - Air pollution costs South Korea more than 10 trillion won (US$8.9 billion) a year in lost production and other damages, with the figure feared to nearly double in about 40 years, data showed Thursday. Air pollution causes direct and indirect damage across the board by not only harming peoples health, but also affecting their leisure activity and industrial production. According to the data by local environmental authorities, scholars and the Organization for Economic Cooperation and Development (OECD), the yearly cost of South Koreas air pollution is estimated to hover above the 10 trillion won mark. Prof. Bae Jeong-hwan of Chonnam National University in Gwangju, about 330 kilometers south of Seoul, even put the figure at 11.8 trillion won. The estimates measured the harmful effects of such air pollutants as particulates, volatile organic compounds, nitrogen oxides and sulfur oxides. According to conservative estimates, the damage from air pollution in South ...

In 2002, Narayan Sastry, currently a professor of demography at the University of Michigan, published a paper entitled Forest Fires, Air Pollution, and mortality in SE Asia in the February 2002 issue of the journal Demography. The smog of 1997 coincided with an El Niño year which had intensified the seasonal mid-year drought. The land clearing and forest fires in that year burnt an estimated 2-3 percent of Indonesian land area, mostly in Sumatra and Kalimantan but also affecting sizeable tracts in Irian Jaya, Sulawesi, Java, Sumbawa, Komodo, Flores, Sumba, Timor, Wetar as well as areas in Sarawak and Brunei. Sastry obtained daily mortality statistics from the Department of Statistics in Malaysia and correlated these with the daily Air Pollution Index (API) readings from the Malaysian Meteorological Department , in order to analyze the acute mortality in Kuching and Kuala Lumpur following upon days of high air pollution (defined as days when PM 10 , 210 ug/m 3. The Air Pollution Index is ...
Despite improvements in air quality since the 1970s, air pollution remains an important environmental risk to human health. A national health objective for the year 2000 is to reduce exposure to air pollutants so that at least 85% of persons live in counties that meet U.S. Environmental Protection Agency (EPA) standards (objective 11.5) (1). This report provides estimates from the American Lung Association (ALA) of populations potentially at risk from exposure to particulate air pollution in the United States during 1992. The National Ambient Air Quality Standard for particulate matter less than 10 um in diameter (PM10) is 150 ug/m(3), averaged over 24 hours (2). The federal standard is met if this value is not exceeded more than once per calendar year, and the annual arithmetic mean is less than or equal to 50 ug/m(3). Information in this report is based on the second highest maximum 24-hour PM10 concentrations recorded by at least one monitor in 1992 (EPA, unpublished data, 1993). Both the ...

The U.S. Environmental Protection Agency (EPA) approved the state of Oklahomas clean-air plan related to transporting air pollution from fine particulate matter across state lines, known as interstate transport. EPA determined that emissions from pollution sources in Oklahoma do not contribute significantly to diminished air quality in other states.. Controlling particulate matter pollution is important for public health and for maintaining air quality, said Regional Administrator Anne Idsal. Oklahoma has shown its a good neighbor by keeping this pollution from affecting other states.. Because air pollution does not stay within political boundaries, the Clean Air Act requires that state clean-air plans prohibit emissions that will significantly harm air quality in other states. This is commonly called transport or the Good Neighbor requirement. Based on submitted technical information, EPA found that emissions in Oklahoma comply with those requirements. EPAs finding approves state law ...
BACKGROUND: There is increasing concern about the potential effects of traffic-related air pollution (TRAP) on the developing brain. The impact of TRAP exposure on childhood behavior is not fully understood because of limited epidemiologic studies. OBJECTIVE: We explored the association between early-life exposure to TRAP using a surrogate, elemental carbon attributed to traffic (ECAT), and attent

Pregnancy-induced hypertensive disorders can lead to maternal and perinatal morbidity and mortality, but the cause of these conditions is not well understood. We have systematically reviewed and performed a meta-analysis of epidemiological studies investigating the association between exposure to ambient air pollution and pregnancy-induced hypertensive disorders including gestational hypertension and preeclampsia. We searched electronic databases for English language studies reporting associations between ambient air pollution and pregnancy-induced hypertensive disorders published between December 2009 and December 2013. Combined risk estimates were calculated using random-effect models for each exposure that had been examined in ≥4 studies. Heterogeneity and publication bias were evaluated. A total of 17 articles evaluating the impact of nitrogen oxides (NO2, NOX), particulate matter (PM10, PM2.5), carbon monoxide (CO), ozone (O3), proximity to major roads, and traffic density met our ...
This article was originally published at and has been reposted here with permission.. While smog is yet one of the many problems afflicting Los Angeles, this blog entry points out that some of LAs famous air pollution comes all the way from China. According to this report, some days have a third of the air over San Francisco and Los Angeles coming from Asia, and along with it, up to three fourths of black carbon particulate air pollution, among other pollutants. Just how does Chinese pollution get to the US? Is it just the fault of the Chinese?. Some of this pollution begins as naturally occurring dust plumes from the Gobi desert, whipped up by storms every spring and summer. As the dust travels west, it picks ups pollutants as it travels through heavily industrialized parts of China. Those pollutants include the end products of coal burning, a common source of power in China.. While the US may complain about the pollution, it does contribute to the problem. Various loopholes and ...
Introduction. A vast area under discussion, mostly in this day and age, pollution is a poisonous or harmful contamination of the biosphere. There are many different forms of pollution including litter, industrial effluent, domestic waste, nuclear waste, toxic waste, water pollution, agricultural pollution, noise pollution and air pollution. Air pollution, being the main area of concern due to its threatening symptoms, comes from a range of various sources such as factories, power plants, dry cleaners, motor vehicles and even windblown dust and wildfires. It can be divided into particulate and gaseous pollutants. Particulate pollutants consist largely of dust and smoke. Gaseous pollutants are caused by the burning of fuels (wood, oil, coal) and consist mostly of sulphur oxides, nitrogen oxides and carbon monoxide etc. Ever since the passenger vehicle was invented, air pollution has been an escalating worry. In the U.S. there is approximately 770 cars per 1000 people. In many urban areas, motor ...
It is obvious that all humans desire to breathe clean air. In a progressively urbanized world, pollution and air quality are essential and hotly debated issues. More often than not, we tend to assume that air pollution is something that we face while outdoors in the form of that yellow haze in the air, smog, or ozone depletion. We tend to concentrate more on the outside and ignore the problem inside. Yet, indoor air quality is critical as it concerns all of us.. We spend around 90% of our time indoors, without the knowledge that the air inside our offices, homes, and buildings could be more polluted compared to outside air. For most of us, health risks indoors might be greater than outside. This is due to exposure to allergens, chemicals, particles, and pollutants. The elderly and children are more susceptible to indoor air pollution as they are the most exposed. However, since we all spend a lot of time indoors and that present-day buildings are constructed in such a way that they lock ...

Exposure to air pollution has been linked to elevated blood pressure (BP) and hypertension, but most research has focused on short-term (hours, days, or months) exposures at relatively low concentrations. We examined the associations between long-term (3-year average) concentrations of outdoor PM and household air pollution (HAP) from cooking with solid fuels with BP and hypertension in the Prospective Urban and Rural Epidemiology (PURE) study. Outdoor PM exposures were estimated at year of enrollment for 137,809 adults aged 35-70 years from 640 urban and rural communities in 21 countries using satellite and ground-based methods. Primary use of solid fuel for cooking was used as an indicator of HAP exposure, with analyses restricted to rural participants (n = 43,313) in 27 study centers in 10 countries. BP was measured following a standardized procedure and associations with air pollution examined with mixed-effect regression models, after adjustment for a comprehensive set of potential ...
The Air Pollution and Control Laboratory houses the Air Quality Measurement Laboratory, which determines the quality of the ambient air, and the Emission Measurement Laboratory, which measures flue gas emissions. In addition, the measurement of noise levels for noise mapping studies are underway.. In our country in recent years, a new form of pollution called odor pollution has arisen. Our laboratories have the necessary competence and accreditation to measure and evaluate odor pollution. The Air Pollution and Control Laboratory was first given accreditation in 2002 by DAP/DAR of the German Accreditation Agency. This accreditation lasted until 2010. Ever since 2010, accreditation has been given from the Turkish Accreditation Agency. More details can be found in the Industrial Service Catalog.. Our laboratory has been given the TS ISO/IEC 17025 accreditation by the Turkish Accreditation Agency in sampling, measurement, and analysis of quite a few parameters. Flue gas measurement and analysis has ...
Street canyons are ubiquitous in urban areas. Traffic-related air pollutants in street canyons can adversely affect human health. In this study, an urban-scale traffic pollution dispersion model is developed considering street distribution, canyon geometry, background meteorology, traffic assignment, traffic emissions and air pollutant dispersion. In the model, vehicle exhausts generated from traffic flows first disperse inside street canyons along the micro-scale wind field generated by computational fluid dynamics (CFD) model. Then, pollutants leave the street canyon and further disperse over the urban area. On the basis of this model, the effects of canyon geometry on the distribution of NOx and CO from traffic emissions were studied over the center of Beijing. We found that an increase in building height leads to heavier pollution inside canyons and lower pollution outside canyons at pedestrian level, resulting in higher domain-averaged concentrations over the area. In addition, canyons with ...

Almost everyone is familiar with this side of the air pollution story: outdoor pollution can have a bad impact on our health. But have you thought about how pollution indoors can affect your health and well-being? Just like outdoor air pollution, indoor air pollution has a high cost. For example, in France the health costs of indoor air pollution is approximately 19 billion euros per year, according to a recent study.. How much time do you spend indoors? Do you think it is about half your day, or a little less or a little more?. Many of us spend about 90% of our time indoors: at our home, office, school, shops and restaurants. While indoor air quality at home is often entirely in our own hands, at work it is in the hands of our employers.. Factors like mould and bacteria, volatile organic compounds, and gases such as carbon monoxide and radon can affect indoor air quality at work. Tobacco smoke is another major source of air pollution in the workplace; it alone can involve about 4 000 different, ...
INCINERATOR AIR POLLUTION CONTROL (APC) CAPACITY SIMULATION PROJECT The client operates a hazardous waste incineration facility. The incineration process has an air pollution control system (APC) to remove contaminants from the combustion gases generated during the incineration process. The APC consists of three (3) wet scrubbing steps - saturator, condenser, and high energy (venturi) scrubber, followed by a baghouse filtration system. Draft for the combustion and APC processes is provided by an induced draft fan. Solids in the combustion gas accumulate and plug the process side of the plate-and-frame heat exchangers utilized in the condensing step. Plugged heat exchangers lead to poor heat transfer and higher condenser outlet temperatures, which in turn lead to reduced system capacity.. Process Engineering Associates, LLC (PROCESS) was contracted by the client to assist the clients process engineer in modeling the overall APC process utilizing PROCESS (and the clients) licensed commercial ...
Politi-cians and bu-reau-crats across the world - at lo-cal, re-gional and na-tional lev-els - have been com-ing up with new ideas to re-duce air pollution. More re-cently, some have pointed the fin-ger at ru-ral con-tri-bu-tions to air pollution in the de-vel-op-ing world, es-pe-cially in In-dia and China.. Dur-ing Di-wali cel-e-bra-tions at the end of Oc-to-ber, New Delhis pollution level was off the charts, ce-ment-ing the In-dian cap-i-tals sta-tus as the worlds most pol-luted megac-ity and rekin-dling a na-tion-wide de-bate on In-dias killing smog.

Using the most comprehensive data file ever compiled on air pollution, water pollution, environmental regulations, and infant mortality from a developing country, the paper examines the effectiveness of Indias environmental regulations. The air pollution regulations were effective at reducing ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide. The most successful air pollution regulation is associated with a modest and statistically insignificant decline in infant mortality. However, the water pollution regulations had no observable effect. Overall, these results contradict the conventional wisdom that environmental quality is a deterministic function of income and underscore the role of institutions and politics. ...
Background: Secondhand smoke (SHS) and ambient air pollution (AAP) exposures have been associated with increased prevalence and severity of asthma and DNA modifications of immune cells. In the current study, we examined the association between SHS and AAP with DNA methylation and expression of interferon-gamma (IFN-γ) and forkhead box protein 3 (Foxp3) in T cell populations. Methods: Subjects 7-18 years old were recruited from Fresno (high AAP; n = 62) and Stanford, CA (low AAP; n = 40) and divided into SHS-exposed (Fresno: n = 31, Stanford: n = 6) and non-SHS-exposed (nSHS; Fresno: n = 31, Stanford: n = 34) groups. T cells purified from peripheral blood were assessed for levels of DNA methylation and expression of IFN-γ (in effector T cells) or Foxp3 (in regulatory T cells). Results: Analysis showed a significant increase in mean % CpG methylation of IFN-γ and Foxp3 associated with SHS exposure (IFN-γ: FSHS 62.10%, FnSHS 41.29%, p | 0.05; SSHS 46.67%, SnSHS 24.85%, p | 0.05; Foxp3: FSHS 74.60%,
Downloadable (with restrictions)! Intuitively, the concept of an Environmental Kuznets Curve (EKC) is relatively easy to understand: pollution will initially increase with economic development but then decrease again as incomes attain a certain level. The overall concept of pollution, however, actually consists of various components which may behave differently and are not easily combined into a single measure. As a result, the measurement or tracking of an EKC becomes more difficult as one tries to develop a tractable measure of pollution for modeling or policy purposes. For example, in China levels of sulfur dioxide and particulate pollution show some signs of diminishing while nitrogen dioxide levels have increased as Chinas auto fleet has grown. Consequently, different studies estimating an EKC often generate different results depending upon which pollutant is used and how it is measured. This paper generates composite measures of Chinese air pollution using Nemerow methodology as well as a new
The study used cardiac magnetic resonance imaging (MRI) to look at the hearts of 3,896 subjects that had no cardiovascular diseases at the beginning of the study. Researchers also determined the levels of nitrous dioxide surrounding each subjects home. Researchers found that there was an association between higher nitrous oxide levels and changes in the right ventricul of the heart.. Dr. Peter Leary, lead author of the study, said in a new release that, Although the link between traffic-related air pollution and left ventricular hypertrophy, heart failure, and cardiovascular death is established, the effects of the traffic-related air pollution on the right ventricle have not been well studied.. The Environmental Protection Agency began investigating pollution resulting from fossil fuels back in the 1970s, and found in 2010 that by decreasing sulfur dioxides, nitrous oxides and other particulate matter, environmental regulations were able to effectively prevent 130,000 heart attacks, 86,000 ...
‘Hawa Badlo’ allows people in NCR to report on incidences of air pollution such as garbage burning and sends these to officials who will then take action. This is in compliance with directions of the Hon’ble Supreme Court on air pollution control 
A version of this post was originally published by Maria Fernanda Cavalcanti in Portuguese on TheCityFix Brasil on June 27, 2011.. Air pollution in the capital of Chile has reached alarming rates, forcing the city to declare a Level 2, pre-emergency, environmental alert on Monday, June 27, 2011. Previously, the government of Santiago had declared a second pre-emergency environmental alert in early June. Air monitoring stations recorded pollution levels at 300 to 500 micrograms per cubic meter of particles hazardous to health, exceeding the World Health Organization (WHO)s acceptable levels of 50 micrograms per cubic meter by a factor of ten.. In response to the current levels of air pollution, officials have been enforcing vehicle use restrictions. The decision restricts the movement of 20 percent of vehicles around the perimeter of Santiago, which corresponds to about 310,000 fewer cars on the streets.

New Delhi : The International Energy Agency in its recent report World Energy Outlook Special Report on Energy and Air Pollution has reaffirmed Greenpeace Indias previously-stated position on thermal power plants contributing significantly to high levels of air pollution. The IEA report released today suggests that 85 percent of particulate matter and almost all of the sulphur oxides and nitrogen oxides result from fuel combustion. According to the report around 60 percent of global combustion-related sulphur dioxide emissions originate from coal. The same was also highlighted through Greenpeace Indias latest report Out of Sight which depicted presence of SO2 hotspots at the coal consuming hotspots in the country using analysis done on satellite data from NASA. According to the IEA report: Global fuel combustion increases steadily in our main scenario, to help meet a one-third rise in global energy demand. But global emissions of particulate matter are projected to fall by 7 percent, ...

Your chosen mask should be airtight and form a tight seal around your face. However, some experts warn that wearing surgical style or basic cotton masks can be more detrimental than wearing nothing at all. These types of mask are rarely effective against significant air pollution levels, yet they can create a false sense of security, leading more people to increase their exposure as they linger outdoors. While President Xi Jinping may feel comfortable breathing in 500 AQI polluted air, most of us would feel a little more confident wearing the adequate protection. The most important consideration when choosing an air pollution mask is how it fits against your face. An air gap will allow air particulate to be breathed in, basically rendering your mask useless. Many masks may advertise that they are 99% effective, but you need to use your own judgment. If you are wearing glasses and a mask, and your lenses steam up, your mask is not airtight. You also need to consider the material used to ...

After five months of negotiations behind closed doors, China has finally announced a detailed air pollution action plan to cut fine particle PM2.5 pollution and clear the skies above the country. The plan, for the first time, sets out to cut coal consumption in a way which could significantly affect Chinas upward coal-use trend, and even the future of our climate.. In Greenpeaces Beijing coal team we have campaigned for years to achieve this. After hearing about the negotiations we have been holding our collective breath while intensifying campaigning to increase public momentum of the air pollution debate. Even the negotiation process has been an unprecedented move in Chinese energy policy, juxtaposing the growing public demand for clean environment against the old policy of maximising the GDP.. Two years ago, when our coal campaign started, something like this would have been called, well, Greenpeace dreaming the impossible. But it has not come from nothing. It has taken unparalleled levels ...
