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)

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 ...
Based on air pollution levels at 5 a.m on Sept. 4, a Stage 1 Air Pollution Health Advisory has been issued for Mono County communities by the local air pollution control district. Due to elevated particulate pollution levels, children, the elderly, people with heart or lung problems, or people with current illnesses such as the flu, are advised to stay indoors and avoid strenuous outdoor activities in the impacted areas.. Smoke conditions may change quickly. Both Mono County and Owens Valley communities may have impacts throughout the holiday weekend.

If youre at home and its a hot day out, rather than opening the windows, turn on the air conditioning to keep pollution out ...
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 ...

The Aerosol and Air Pollution Group is a multidisciplinary team at CityU focusing on the investigating the sources, characteristics, impacts and control of urban air pollution. Our mission is to contribute to the development of systematic and fundamental knowledge on air pollution to inform effective air quality management and to develop break-through technologies and control strategies to protect public health and mitigate climate change. Our research activities include the physicochemical and toxicological characterization of aerosol and air pollution from traffic sources and in urban atmospheric environment, and the characterization of personal exposure in complex and heterogeneous microenvironments. We also devise and develop new and aerosol related measurement and control technologies to meet the emerging environmental challenges. ...
A study published in Environment International has demonstrated that exposure to air pollution on the way to school can have damaging effects on childrens cognitive development. The study, led by the Barcelona Institute for Global Health, found an association between a reduction in working memory and exposure to fine particulate matter (PM2.5) and black carbon during the walking commute to and from school.
HEI funded the National Morbidity, Mortality, and Air Pollution Study (NMMAPS) to characterize the effects of airborne particles less than 10 ?m in aerodynamic diameter (PM10) alone and in combination with gaseous air pollutants in a consistent way in a large number of cities. The study was designed to select multiple locations based on the specific criteria of population size and availability of PM10 data from the US Environmental Protection Agency?s Aerometric Information Retrieval System (AIRS) database, and to apply the same statistical procedures to all locations. Dr Jonathan Samet and his colleagues at Johns Hopkins University conducted a time-series study of mortality effects in large US cities representing various levels of PM10 and gaseous pollutants. In their analysis, the investigators first estimated risk in each city using the same method and then combined these results systematically to draw more information than any single city could provide. The 20 and 90 largest cities were ...
The Washington Clean Air Act, Ch. 70.94 RCW, sets forth the state law regarding outdoor air pollution and establishes a system of regional air pollution control authorities, Local Clean Air Agencies (DOE), to implement federal and state air pollution control regulations.. Air pollution control regulations cover the emission of air contaminants that are injurious to health or that unreasonably interfere with the enjoyment of life and property. Pursuant to RCW 70.94.230, the rules and regulations adopted by an air pollution control authority, pursuant to the Washington Clean Air Act, preempt local ordinances for the regulation of air pollution. RCW 70.94.230 does, however, authorize cities and towns to enact and enforce local nuisance provisions and performance standards incorporated in zoning ordinances, so long as such standards relating to air pollution control or air quality are not less stringent than those of the authority. Many local governments have enacted general nuisance ordinances, ...
Accurate and reliable exposure estimates are crucial to the success of any environmental health study. The overarching goal of this project is to develop and apply statistical methods to improve exposure assessment and exposure uncertainty quantification for spatio-temporal environmental pollution fields. This is accomplished by statistically integrating observations with additional data sources, including state-of-the-art computer model simulations and satellite imagery. We will develop methods motivated by three current research priorities in air pollution epidemiology: a) identifying susceptible sub-populations most at risk to air pollution exposures; (b) quantifying health impacts of air pollution under a changing climate; and (c) understanding sources of air pollution to develop control strategies. In Aim 1, we will develop multi-resolutional and multivariate data integration methods for ambient air pollution concentrations. We will supplement sparse observations from monitoring networks ...
