Use of wood stoves and risk of cancers of the upper aero-digestive tract: a case-control study. (1/1407)

BACKGROUND: Incidence rates for cancers of the upper aero-digestive tract in Southern Brazil are among the highest in the world. A case-control study was designed to identify the main risk factors for carcinomas of mouth, pharynx, and larynx in the region. We tested the hypothesis of whether use of wood stoves is associated with these cancers. METHODS: Information on known and potential risk factors was obtained from interviews with 784 cases and 1568 non-cancer controls. We estimated the effect of use of wood stove by conditional logistic regression, with adjustment for smoking, alcohol consumption and for other sociodemographic and dietary variables chosen as empirical confounders based on a change-in-estimate criterion. RESULTS: After extensive adjustment for all the empirical confounders the odds ratio (OR) for all upper aero-digestive tract cancers was 2.68 (95% confidence interval [CI] : 2.2-3.3). Increased risks were also seen in site-specific analyses for mouth (OR = 2.73; 95% CI: 1.8-4.2), pharyngeal (OR = 3.82; 95% CI: 2.0-7.4), and laryngeal carcinomas (OR = 2.34; 95% CI: 1.2-4.7). Significant risk elevations remained for each of the three anatomic sites and for all sites combined even after we purposefully biased the analyses towards the null hypothesis by adjusting the effect of wood stove use only for positive empirical confounders. CONCLUSIONS: The association of use of wood stoves with cancers of the upper aero-digestive tract is genuine and unlikely to result from insufficient control of confounding. Due to its high prevalence, use of wood stoves may be linked to as many as 30% of all cancers occurring in the region.  (+info)

Exposure to nitrogen dioxide and the occurrence of bronchial obstruction in children below 2 years. (2/1407)

BACKGROUND: The objective of the investigation was to test the hypothesis that exposure to nitrogen dioxide (NO2) has a causal influence on the occurrence of bronchial obstruction in children below 2 years of age. METHODS: A nested case-control study with 153 one-to-one matched pairs was conducted within a cohort of 3754 children born in Oslo in 1992/93. Cases were children who developed > or = 2 episodes of bronchial obstruction or one episode lasting >4 weeks. Controls were matched for date of birth. Exposure measurements were performed in the same 14-day period within matched pairs. The NO2 exposure was measured with personal samplers carried close to each child and by stationary samplers outdoors and indoors. RESULTS: Few children (4.6%) were exposed to levels of NO2 > or = 30 microg/m3 (average concentration during a 14-day period). In the 153 matched pairs, the mean level of NO2 was 15.65 microg/m3 (+/-0.60, SE) among cases and 15.37 (+/-0.54) among controls (paired t = 0.38, P = 0.71). CONCLUSIONS: The results suggest that NO2 exposure at levels observed in this study has no detectable effect on the risk of developing bronchial obstruction in children below 2 years of age.  (+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. (3/1407)

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)

Contributory and exacerbating roles of gaseous ammonia and organic dust in the etiology of atrophic rhinitis. (4/1407)

Pigs reared commercially indoors are exposed to air heavily contaminated with particulate and gaseous pollutants. Epidemiological surveys have shown an association between the levels of these pollutants and the severity of lesions associated with the upper respiratory tract disease of swine atrophic rhinitis. This study investigated the role of aerial pollutants in the etiology of atrophic rhinitis induced by Pasteurella multocida. Forty, 1-week-old Large White piglets were weaned and divided into eight groups designated A to H. The groups were housed in Rochester exposure chambers and continuously exposed to the following pollutants: ovalbumin (groups A and B), ammonia (groups C and D), ovalbumin plus ammonia (groups E and F), and unpolluted air (groups G and H). The concentrations of pollutants used were 20 mg m-3 total mass and 5 mg m-3 respirable mass for ovalbumin dust and 50 ppm for ammonia. One week after exposure commenced, the pigs in groups A, C, E, and G were infected with P. multocida type D by intranasal inoculation. After 4 weeks of exposure to pollutants, the pigs were killed and the extent of turbinate atrophy was assessed with a morphometric index (MI). Control pigs kept in clean air and not inoculated with P. multocida (group H) had normal turbinate morphology with a mean MI of 41.12% (standard deviation [SD], +/- 1. 59%). In contrast, exposure to pollutants in the absence of P. multocida (groups B, D, and F) induced mild turbinate atrophy with mean MIs of 49.65% (SD, +/-1.96%), 51.04% (SD, +/-2.06%), and 49.88% (SD, +/-3.51%), respectively. A similar level of atrophy was also evoked by inoculation with P. multocida in the absence of pollutants (group G), giving a mean MI of 50.77% (SD, +/-2.07%). However, when P. multocida inoculation was combined with pollutant exposure (groups A, C, and E) moderate to severe turbinate atrophy occurred with mean MIs of 64.93% (SD, +/-4.64%), 59.18% (SD, +/-2.79%), and 73.30% (SD, +/-3.19%), respectively. The severity of atrophy was greatest in pigs exposed simultaneously to dust and ammonia. At the end of the exposure period, higher numbers of P. multocida bacteria were isolated from the tonsils than from the nasal membrane, per gram of tissue. The severity of turbinate atrophy in inoculated pigs was proportional to the number of P. multocida bacteria isolated from tonsils (r2 = 0.909, P < 0.05) and nasal membrane (r2 = 0.628, P < 0.05). These findings indicate that aerial pollutants contribute to the severity of lesions associated with atrophic rhinitis by facilitating colonization of the pig's upper respiratory tract by P. multocida and also by directly evoking mild atrophy.  (+info)

Double exposure. Environmental tobacco smoke. (5/1407)

One study after another is finding strong associations between a variety of human illness and exposure to environmental tobacco smoke (ETS). A 1986 report by the U.S. Surgeon General concluded that ETS is a cause of disease, including lung cancer, in healthy nonsmokers. Other reports have documented causal associations between ETS and lower respiratory tract infections, middle ear disease and exacerbation of asthma in children, heart disease, retardation of fetal growth, sudden infant death syndrome, and nasal sinus cancer. However, the findings from many of these studies remain controversial. A number of scientists remain skeptical about the association between ETS and serious illness in nonsmokers, charging that scientific journals either fail to publish pro-tobacco findings and meta-analyses or disregard those that are published. They also claim that many epidemiological studies declare causal associations based on marginal odds ratios.  (+info)

Health impacts of domestic coal use in China. (6/1407)

Domestic coal combustion has had profound adverse effects on the health of millions of people worldwide. In China alone several hundred million people commonly burn raw coal in unvented stoves that permeate their homes with high levels of toxic metals and organic compounds. At least 3,000 people in Guizhou Province in southwest China are suffering from severe arsenic poisoning. The primary source of the arsenic appears to be consumption of chili peppers dried over fires fueled with high-arsenic coal. Coal samples in the region were found to contain up to 35,000 ppm arsenic. Chili peppers dried over high-arsenic coal fires adsorb 500 ppm arsenic on average. More than 10 million people in Guizhou Province and surrounding areas suffer from dental and skeletal fluorosis. The excess fluorine is caused by eating corn dried over burning briquettes made from high-fluorine coals and high-fluorine clay binders. Polycyclic aromatic hydrocarbons formed during coal combustion are believed to cause or contribute to the high incidence of esophageal and lung cancers in parts of China. Domestic coal combustion also has caused selenium poisoning and possibly mercury poisoning. Better knowledge of coal quality parameters may help to reduce some of these health problems. For example, information on concentrations and distributions of potentially toxic elements in coal may help delineate areas of a coal deposit to be avoided. Information on the modes of occurrence of these elements and the textural relations of the minerals and macerals in coal may help predict the behavior of the potentially toxic components during coal combustion.  (+info)

Tobacco smoke exposure at one month of age and subsequent risk of SIDS--a prospective study. (7/1407)

The aim of this investigation was to identify the sources of postnatal exposure to tobacco smoke at 1 month of age and to examine their relation to sudden infant death syndrome (SIDS). The Tasmanian Infant Health Survey was a prospective cohort study undertaken from 1988 to 1995. It involved 9,826 infants (89% of eligible infants) at higher risk of SIDS. Subsequently 53 eligible infants died of SIDS. Hospital interviews were available on 51 and home interviews on 35 SIDS infants. Urinary cotinine assays were conducted using gas-liquid chromatography (n = 100). Within a predictive model that explained 63% of urinary cotinine variance, the strongest predictor of cotinine and also of SIDS was maternal smoking, though the effects of prenatal and postnatal smoking could not be separated. However, for particular smoking-related behaviors, there was a discordance between prediction of cotinine concentration and prediction of risk of SIDS. If smoking mothers did not smoke in the room with the baby, the cotinine level in the infant's urine was reduced by a little more than a half (p = 0.009), but this was not associated with a reduction in SIDS risk (odds ratio = 1.09, 95% confidence interval 0.47-2.55). Similarly, the presence of other adult resident smokers was associated with a 63% increase in urinary cotinine (p = 0.047) but not with increased SIDS risk (odds ratio = 0.69, 95% confidence interval 0.34-1.40). However, the study lacked the power to detect modest effects, that is, those altering risk less than twofold.  (+info)

Role of the indoor environment in determining the severity of asthma. (8/1407)

Allergen exposure can confound the management of asthma. To understand the potential mechanisms by which allergens increase the steroid requirements in atopic asthmatics, we examined the effects of allergens on glucocorticoid receptor (GCR) binding affinity and glucocorticoid (GC) responsiveness of peripheral blood mononuclear cells (PBMC) from atopic asthmatics. A significant reduction (p < 0.001) in the GCR binding affinity (Kd) was observed in ragweed-allergic asthmatics during ragweed pollen season compared with PBMC obtained before and after ragweed season. In vitro effects of allergen on PBMC GCR Kd were also examined by incubating PBMC from atopic asthmatics with allergen (ragweed and cat) versus Candida albicans. GCR binding affinity was significantly reduced after incubation with ragweed (p < 0.001) or cat allergen (p < 0.001) compared with baseline or C. albicans stimulation. This effect was limited to atopic asthmatics in that in vitro cat allergen incubation for 48 h failed to significantly alter GCR binding affinity in nonasthmatic, atopic individuals. These allergen-induced reductions in GCR binding affinity also rendered the PBMC less sensitive to the inhibitory effects of hydrocortisone and dexamethasone on allergen-induced proliferation (p < 0.01). To test the hypothesis that allergen-induced alterations in GCR binding affinity were cytokine-induced, we examined the effects of interleukin-2 (IL-2) and IL-4 neutralization using anticytokine antibodies. Addition of both anti-IL-2 and anti-IL-4 antibodies resulted in a significant (p < 0.001) inhibition of allergen-induced alterations in GCR binding affinity. Furthermore incubation with cat allergen induced significantly higher concentrations of IL-2 (p = 0.03) and IL-4 (p = 0.02) by PBMC from atopic as compared with nonatopic subjects. Our current observations suggest that allergen exposure may contribute to poor asthma control by reducing GCR binding affinity in mononuclear cells. This appears to be mediated through IL-2 and IL-4. These findings may have important implications for novel approaches to the treatment of poorly controlled asthma.  (+info)

Indoor air pollution caused by the indoor burning of solid biomass fuels has been associated with Acute Respiratory Infections such as pneumonia amongst children of less than five years of age. Behavioural change interventions have been identified as a potential strategy to reduce child indoor air pollution exposure, yet very little is known about the impact of behavioural change interventions to reduce indoor air pollution. Even less is known about how behaviour change theory has been incorporated into indoor air pollution behaviour change interventions. A review of published studies spanning 1983-2013 suggests that behavioural change strategies have the potential to reduce indoor air pollution exposure by 20%-98% in laboratory settings and 31%-94% in field settings. However, the evidence is: (1) based on studies that are methodologically weak; and (2) have little or no underlying theory. The paper concludes with a call for more rigorous studies to evaluate the role of behavioural change strategies
Hyderabad: Accounting for about 2 million premature deaths every year in the country, latest figures indicate that more people are dying due to poor indoor air quality as compared to outdoor air pollution1. Indoor air pollution can be up to 10 times worse than outdoor air pollution. However, despite such high risk, experts point out that even people with respiratory conditions are oblivious to the risks of indoor air pollution.. "In urban settings, it is poor ventilation, dust, mites, pollens and other trapped irritants that make the air quality extremely unhealthy for breathing. While children under the age of five are prone to developing respiratory conditions if exposed to indoor air pollution, people with existing condition report exacerbation, leading to increased mortality. One of the recent studies reports that poor indoor air quality is the second largest killer in India, claiming 1.3 million lives every year," says Dr. VV Ramana Prasad ,Sr.Consultant Pulmonologist, KIMS ...
A third of the worlds population uses solid fuel derived from plant material (biomass) or coal for cooking, heating, or lighting. These fuels are smoky, often used in an open fire or simple stove with incomplete combustion, and result in a large amount of household air pollution when smoke is poorly vented. Air pollution is the biggest environmental cause of death worldwide, with household air pollution accounting for about 3·5-4 million deaths every year. Women and children living in severe poverty have the greatest exposures to household air pollution. In this Commission, we review evidence for the association between household air pollution and respiratory infections, respiratory tract cancers, and chronic lung diseases. Respiratory infections (comprising both upper and lower respiratory tract infections with viruses, bacteria, and mycobacteria) have all been associated with exposure to household air pollution. Respiratory tract cancers, including both nasopharyngeal cancer and lung cancer, are
The Scientific Committee on Health and Environmental Risks (SCHER), one of the independent scientific committees managed by the Directorate-General for Health and Consumer Protection of the European Commission, reported that more than 900 different compounds have been detected in indoor air. Figure 1 shows the main indoor air pollutants and related sources. Most indoor pollutants derive from human activity (anthropogenic pollutants). Carbon dioxide (CO2) is a product of human respiration, and elevated levels may be reached in crowded indoor environments with inadequate air exchange, thus altering indoor air quality. Allergens - mainly related to the presence of dust, damp, pets or insects, but also penetrating from outdoors - and infectious agents play an important role in indoor pollution. Indoor air pollution is the eighth most important risk factor for disease, responsible for an estimated 2.7% of the global burden of disease (4% in low-income countries). Conservative estimates show that ...
... An indoor air pollutant is a substance that is present inside buildings that has a harmful health effect on the occupants of the building. Since most people spend more time indoors than outdoors, exposure to indoor air pollutants is an important environmental hazard.. Indoor air pollutants have become a serious problem in recent years due to efforts by builders to make homes and other buildings more energy efficient. Modern buildings are built to restrict the flow of air from the inside out and vice versa. These new building practices work well to save energy.

The impact of building and decoration materials on indoor air quality (IAQ) is now well known and recognized [1, 2]. For many Volatile Organic Compounds (VOCs) found in indoor environments (formaldehyde, α-pinene,…), the main sources are located inside the building [3]. Moreover, the development of low energy buildings which promotes more and more airtight constructions tends to raise indoor pollutant concentration levels. Therefore, indoor air quality became a major public health issue and, in France, a new legislation was implemented. The labeling of all building materials according to their emissions of VOCs is effective since 2013 (decree 2011-321, 23 March 2011), and the compulsory measurement of some pollutants in public buildings (formaldehyde and benzene) is being considered. In the near future, museum and libraries might be concerned.. The preservation of cultural heritage is also challenging as VOCs and carbonyl compounds may damage artwork exposed to the confined atmosphere of ...
Almost three billion people worldwide continue to depend on polluting fuels, including biomass fuels (wood, dung, agricultural residues), kerosene and coal, for their energy needs. Cooking and heating with polluting fuels on open fires or traditional stoves results in high levels of household air pollution. Indoor smoke contains a range of health-damaging pollutants, such as small particles and carbon monoxide, and particulate pollution levels may be 20 times higher than accepted guideline values. There is consistent evidence that exposure to household air pollution can lead to acute lower respiratory infections in children under five, and ischaemic heart disease, stroke, chronic obstructive pulmonary disease and lung cancer in adults. In 2012, household air pollution was responsible for 7.7% of the global mortality.. ...
Source Control. Usually the most effective way to improve indoor air quality is to eliminate individual sources of pollution or to reduce their emissions. Some sources, like those that contain asbestos, can be sealed or enclosed; others, like gas stoves, can be adjusted to decrease the amount of emissions. In many cases, source control is also a more cost-efficient approach to protecting indoor air quality than increasing ventilation because increasing ventilation can increase energy costs. Specific sources of indoor air pollution in your home are listed later in this section.. Ventilation Improvements. Another approach to lowering the concentrations of indoor air pollutants in your home is to increase the amount of outdoor air coming indoors. Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house.

Indoor air quality (IAQ) is a term which refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria), or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings. Residential units can further improve indoor air quality by routine cleaning of carpets and area rugs. Determination of IAQ involves the collection of air samples, monitoring human exposure to pollutants, collection of samples on building surfaces, and computer modelling of air flow inside buildings. IAQ is part of indoor environmental quality (IEQ), which includes IAQ as well as other physical and psychological aspects of life indoors (e.g., ...
Reduction of indoor air pollution (IAP) exposure from solid fuel use is a potentially important intervention for childhood pneumonia prevention. This review updates a prior meta-analysis and investigates whether risk varies by etiological agent and pneumonia severity among children aged less than 5 years who are exposed to unprocessed solid fuels. Searches were made of electronic databases (including Africa, China and Latin America) without language restriction. Search terms covered all sources of IAP and wide-ranging descriptions of acute lower respiratory infections, including viral and bacterial agents.. From 5317 studies in the main electronic databases (plus 307 African and Latin American, and 588 Chinese studies, in separate databases), 25 were included in the review and 24 were suitable for meta-analysis. Due to substantial statistical heterogeneity, random effects models were used. The overall pooled odds ratio was 1.78 (95% confidence interval, CI: 1.45-2.18), almost unchanged at 1.79 ...
... assessments usually begin by conducting a visual inspection to identify areas/equipment that may be sources of pollutants, then determine their correlation with existing ventilation systems. Areas of potentially high pollutant concentrations are identified and air sampler units are installed. Air samples are analyzed for quantitative results of pollutant concentrations and evaluated to determine if there is a potential threat to health or the environment. Although Ontario does not have legislation that deals with indoor air quality, there are guidelines published by Health Canada, the Occupational Safety and Health Act(OSHA) and by the National Institute for Occupational Safety and Health (NIOSH). Comco Canada Inc. uses the standards published in these guidelines as well as best practices when conducting indoor air quality assessments.. ...

Manindu Weerasinghe, a Kansas State University doctoral candidate in chemistry, Sri Lanka, is studying materials that use light or darkness to purify air filled with toxins that are harmful to human health and the environment. Her research could one day lead to filters, humidifiers and other devices that can detoxify air in windowless rooms, manufacturing facilities and other indoor areas.. "Indoor pollutants can come from things like asbestos, markers and new carpet, and are very harmful in just small amounts," Weerasinghe said. "A room like an office or a laboratory that may have few or no windows will have higher levels of indoor air pollutants than a room that has lots of windows. Also, if the room does not have good ventilation those levels would increase.". For her research, Weerasinghe is testing and analyzing photocatalysts and dark catalysts -- ...
By Nate Adams. Weve all seen the studies: Our Indoor Air Quality is terrible! Its KILLING MILLIONS!!. The problem with these studies is that if youre like me you thought; "great, another scare tactic." Or "its really only a problem in Asia." Or of course, "Indoor Air Quality (IAQ) may be a problem in someone elses house, but not mine." Even if youve read that poor IAQ is being found to be a cause of childhood asthma and mental illness, or that air pollution is the single largest environmental health risk according to the World Health Organization, it still feels too remote to worry about it.. To further enforce the disconnect, short of a government study, there has been no clear way for the average person could gain even the vaguest insight into their indoor air quality (but heres a hint, if you use air "fresheners," you have an IAQ problem.). Well, thats all changed, no more guessing. Average Joes like you and me can now get a pretty good picture of how good or bad the air in our homes ...
People are one of the sources for deterioration of the indoor air quality. They worsen indoor air quality by their presence (respiration, bio-effluents), activities and habits. Through respiration, people decrease the oxygen concentration in the air of the occupied space and increase carbon dioxide and water vapor concentration in the indoor air as well as its temperature. The goal of the AIRMEN project is to find out if the rate of consumption of oxygen and emission of carbon dioxide (and water vapor) by people depends on the indoor air temperature as well as carbon dioxide concentration in the inhaled air. In order to achieve this goal a small climate chamber must be designed and constructed which allows for controlling and measuring both inflow and exposure parameters as well as for measuring outflow parameters. The principal goal of this paper is to present some important details, obtained by CFD simulations, from the design process of the climate chamber which precondition the air ...
We made these videos as part of a technical communication exchange course, which was part of an NSF IGERT Program in Indoor Environmental Science and Engineering at UT (PIs included microBEnet affiliates Rich Corsi, Jeff Siegel, and Kerry Kinney). The goal was to make a 2-minute video about indoor air quality issues, but we also had to place logos in the background for ISIAQ (International Society of Indoor Air Quality and Climate) and Indoor Air 2011 (ISIAQs flagship conference, which was being held in Austin that year). Our class made several of these, which we then used to demonstrate to other students around the world how to (roughly) go about making their own similar videos for a student video competition at Indoor Air 2011. With our video we were trying to communicate a few basic ideas of IAQ in homes but in a humorous manner so maybe it was a little easier to digest. We crafted our Real World scenario around an inconsiderate roommate who wasnt aware of issues like smoking indoors (which ...
Air pollution is a problem present in the majority of the built environments. Ambient air pollution is consisted by many different pollutants which, depending on their concentration in the air, can have a severe impact on human health with long-term implications, and they can also deteriorate the surfaces of the buildings they come in contact with. Fine Particulate Matter (PM2.5) is amongst them. It is a pollutant that tends to exceed the allowable levels and that can have a severe impact on human health, as it is able to penetrate deep into the human respiratory system. Ambient air pollution is directly connected with Indoor Air Quality through infiltration and ventilation. In order to ensure good Indoor Air Quality and user comfort, the air introduced indoors needs to comply with specific standards. Air-pollution control doesnt address the issue of pollutants already in the atmosphere, and for reducing those other filtration methods need to be applied. These practices can be energy consuming, ...
Johns Hopkins University identified an association between increasing levels of indoor particulate matter pollution and the severity of asthma sympotms among children. The study is among the first to examine the effects of indoor particulate matter pollution.

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 ...
We spend more of our time indoors than we do outdoors. People spend as much as 90% of their lives inside. If you think about it, a majority of things that we do are inside - sleeping, eating, working, relaxing, etc. The quality of our indoor air is not as high as the quality of outdoor air, which can lead to many health related risks and issues for everyone.. When most people think about air that can be damaging to their health they think about contaminants in an outdoor environment, but these people should be considering the damaging effects that indoor air can have on ones health. Inside air can be polluted from any number of sources. Some sources of interior pollution can be paints, tobacco smoke, cooking, cleaning products, heating the home, and fumes from building materials, just to name a few.. There have been studies that have shown that the levels of indoor pollutants can be 25% - 62% higher than the levels of outdoor toxins. These interior impurity levels can even get up to one hundred ...

In many parts of the world, a picture of a woman sitting in front of a smoky cookstove preparing a family meal remains an iconic picture of life today. For many families, the three- stone fire or a traditional stove as a cooking device has not changed over centuries. This need not be the case, and in a growing number of nations, that traditional pattern is changing.. Serious research on improved cookstoves dates back to the 1950s. However, large-scale field programs focused largely on the inefficiency of designs. While the stoves may appear simple, the socio-cultural systems in which they operate, and their impacts on so many aspects of household and regional health and economics, is far from simple. Many approaches have been tried, with some successes and many failures.. Over the last few years, a more complete view of the full human and environmental health impacts of indoor air pollution and the global impact of the fuel and stove cycle has emerged. Poorly managed fuel systems encourage use ...

Acute respiratory infections (ARI), specifically Severe Pneumonia, are the leading cause of death in children under 5 years of age. Of the nearly 10 million children under 5 who die each year, 1.9 million die from ARI, almost all of which occur in developing countries [1, 2]. Over the years, various studies have identified many risk factors associated with ARI, including malnutrition, zinc deficiency, indoor air pollution (IAP) from solid fuels and tobacco. Proven efficacious interventions have been developed and studied to address risk factors related to nutrition and zinc deficiency but still little is known about IAP and proven effective interventions. Furthermore, little is known about the quantifiable relationship between IAP exposure and disease, specifically ARI.. IAP from cooking with biomass is one of the top ten global health risks [3]. 1.6 million people are estimated to die every year from IAP exposure, of which half of them are children under 5 years of age [4].

An improved understanding of indoor air chemistry would significantly benefit human health. It is estimated that at least 15% of new-onset asthma cases can be attributed to workplace exposures. The 2011 American Thoracic Society report on work exacerbated asthma identified 1) better exposure assessment methods to identify and characterize the complex exposures in workplaces and 2) investigating pathophysiological mechanisms such as neurogenic inflammation and epithelial response to oxidant stress as two of the major research gaps for addressing work exacerbated asthma reduction. Unfortunately even though indoor air is identified as a significant link between occupational lung disease and its prevention/reduction, it has been poorly understood or characterized. Research in gas-phase and surface-phase chemistries, improved field and analytical sampling methods and mechanism-based toxicology may all be used to improve indoor air quality ...

So what exactly is indoor air pollution? We all know what pollution is? More often than not, we all must have heard and associated pollution to be an external problem. Air pollution in your city, water pollution of the rivers and so on. Coming to our homes, pollution that is within the confines of our homes is what indoor pollution is. I was shocked to learn that as early as in the year 1992, the World Bank identified indoor air pollution as one of the four most critical environmental problems being faced globally. One of the articles I read about this stated that this problem affects both rural and urban areas. While rural areas have a variety of different causes of air pollution, that include use of traditional sources of fuel including wood, charcoal and cow dung cakes. Other sources that contribute to indoor air pollution include agricultural activities, including storage of grains and livestock feed. Also, a shocking revelation that came up was the soil too was an important source of air ...

While many of the sources on this topic cover a good deal of information, they neglect to point out that it can also affect our pets health if we have any, not to mention the fact that they themselves (pets) can cause indoor air quality problems. While we want our pets to be happy and healthy, we also want the same for ourselves, so to reduce the pets influence on our indoor environment, you should clean your pet cages, litter boxes, bedding and other areas they frequently rest often. The areas where your pets sleep and rest will need frequent cleaning to avoid creating large deposits of pet hair and pet dander, prevent the pet hair and pet dander from being re-released into the air, and to reduce pet odors. Pet cages and their bedding can hold large accumulations of hair and dander, so they should be cleaned frequently to remove as much hair and dander as possible. It is important to choose bedding items for the pet that can be washed in a washing machine to make cleaning these items as simple ...
Because people in industrialized countries spend as much of 80% to 90% of their time indoors, indoor air pollution has been ranked as one of the worlds greatest public health risks. The United Nations Development Program estimated (1998) that more than two million people die each year due to the presence of toxic indoor air, while other studies estimate that 14 times as many deaths occur globally from poor indoor air quality compared with outdoor air pollution. The economic consequences of polluted indoor air cant be ignored either; one Australian study estimated that the cost of unhealthy indoor air in that country exceeds $12 billion annually, measured in losses of worker productivity, higher medical costs, and increased absenteeism.. As indoor air pollution poses new concerns worldwide, cost effective and easy-to-implement methods are needed to eliminate or reduce ozone concentrations. Activated charcoal filters reduce air pollutants, but installation and maintenance costs can be high. Now, ...
Today we review research into the need for and specifications for monitors to measure indoor air quality which accounts for more deaths globally (4.8 M deaths) than outdoor air quality (3.7 M) and is much less understood by people. People tend to use a number of products such as fragrances, cleaning products etc without being aware of the health risks. Electronic monitors are now available at low economic costs which allow for real-time monitoring at short intervals in ore to detect short spikes and at several locations within a house or building. Another related finding is that outdoor air pollution is highest near the intersection of major roads and as a result, buildings near this location also have higher levels of indoor air pollution- which has implications for the siting of schools, hospitals and offices ...
Household air pollution (HAP) contributes to the global burden of disease. Our primary purpose was to determine whether HAP exposure was associated with reduced lung function and respiratory and non-respiratory symptoms in Belizean adults and children. Our secondary purpose was to investigate whether lifestyle (physical activity (PA) and fruit and vegetable consumption (FV)) is associated with reported symptoms. Belizean adults (n = 67, 19 Male) and children (n = 23, 6 Male) from San Ignacio Belize and surrounding areas participated in this cross-sectional study. Data collection took place at free walk-in clinics. Investigators performed initial screenings and administered questionnaires on (1) sources of HAP exposure; (2) reported respiratory and non-respiratory symptoms and (3) validated lifestyle questionnaires. Participants then performed pulmonary function tests (PFTs) and exhaled breath carbon monoxide (CO). There were no significant associations between HAP exposure and pulmonary function in
Environmental air pollution from factories, power plants and chemical plants gets a lot of press coverage these days, but some of the most offensive sources of indoor air pollution can be right in your own home in Coeur D Alene. This time of year, when most homeowners in cold climates keep windows and doors shut tight, there are even higher concentrations of indoor air pollutants that can affect the health of homeowners and their families.
by hbirch , Dec 16, 2013 , Health. Indoor air pollution, in homes as well as commercial buildings, is being recognized as a serious health problem. Because most people in the United States spend an estimated 90 percent of their time indoors, the health risks of poor indoor air quality can significantly increase the risk of health problems. You may think indoor air pollution wont affect you, but chances are it already has. Have you ever felt nauseated after painting or cleaning? Well, thats a neurotoxin for you. The problem is, these toxins affect you all the time. You might not feel downright sick, but maybe youll feel run down and headachy as the day wears on. And it gets worse. Many of these toxins have a cumulative effect. You never get rid of them. They collect until you reach your threshold. Every year thousands of men, women and children will suffer illnesses from indoor air pollution. (more…). ...
Even at the risk of repeating ourselves (see posts below), we cant stress the importance of good indoor air quality in schools enough.. Children are more vulnerable to environmental pollutants, and schools are often built in areas where outdoor air pollution may be a factor, or they may suffer from poor building maientenance leading to such problems like mold or a high count of allergens.. Like clockwork, experts see an increased number of asthma attacks and diagnoses when the school year begins, and they often blame poor indoor air quality in the buildings.. Industrial pollution and soil vapor intrusion can become even bigger problems, because the indoor air pollutants in these circumstances are often difficult to pinpoint.. Administration officials and parents should request regular indoor air quality tests conducted by professionals, which can provide the most accurate picture of the IAQ at certain times.. Arlington high school fears vapor intrusion. A high school in Arlington, ...
Just because you cant see indoor air pollutants doesnt mean they aren t there. This is the message Sam Gault, president of Gault Energy in Westport, hopes to spread during a month-long campaign called
There are many types and sizes of air cleaners on the market, ranging from relatively inexpensive table-top models to sophisticated and expensive whole-house systems. Some air cleaners are highly effective at particle removal, while others, including most table-top models, are much less so. Air cleaners are generally not designed to remove gaseous pollutants.. The effectiveness of an air cleaner depends on how well it collects pollutants from indoor air (expressed as a percentage efficiency rate) and how much air it draws through the cleaning or filtering element (expressed in cubic feet per minute). A very efficient collector with a low air-circulation rate will not be effective, nor will a cleaner with a high air-circulation rate but a less efficient collector. The long-term performance of any air cleaner depends on maintaining it according to the manufacturers directions.. Another important factor in determining the effectiveness of an air cleaner is the strength of the pollutant source. ...

We recently held a workshop that brought together, perhaps for the first time, researchers in the fields of atmospheric and indoor air chemistry, infection control engineering, building physics, and environmental microbiology. As separate groups of scientists, we tend to focus on discipline-specific problems. Indoor air chemists are largely concerned with chemical reactions indoors and the resulting products and then trying to identify those that may be harmful to health. Members of the indoor biological community, on the other hand, are interested in airborne microorganisms and often work at the frontline of pathogen control. For instance, they may be trying to eliminate infectious agents from a hospital environment, where compromised immunities make some occupants much more susceptible to infection.. Both communities advocate for good ventilation. The expanding desire to make buildings more energy efficient, combined with greater knowledge of the composition of our indoor air, has, in recent ...
New motor vehicles cabins may be critical when considering the indoor air quality, because concentrations of volatile organic compounds are at levels higher than the outdoors. Certain substances present in the cabin air can be harmful to humans according to their toxicity. Assessment of the cabin air becomes necessary. In this study, cabin air quality was assessed and 7 standard popular new vehicles containing same interior trim materials were evaluated. A total of 46 volatile organic compounds were identified, with 14 carbonylic compounds and 32 with aliphatic and aromatic hydrocarbons, halogenated compounds and a nitrogenated compound. The carbonylic compounds were identified and quantified by the liquid chromatography and other VOCs only identified by gas chromatography coupled with mass spectrometry ...

Outdoor air pollution in cities is a major health problem. Much effort and money continue to be spent cleaning up pollution in the outdoor air. But air pollution can be a problem where you least expect it, in the place you may have thought was safest -- your home. Many ordinary activities, such as cooking, heating, cooling, cleaning and redecorating, can cause the release and spread of indoor pollutants at home. Studies have shown that the air in our homes can be even more polluted than outdoor air. Many Americans spend up to 90% of their time indoors, often at home. Therefore, breathing clean indoor air can have an important impact on health. People who are inside a great deal may be at greater risk of developing health problems, or having problems made worse by indoor air pollutants. These people include infants, young children, the elderly and those with chronic illnesses. Many factors determine whether pollutants in your home will affect your health. They include the presence, use and ...

Indoor air quality complaints in institutional buildings (i.e., hospitals and schools) are investigated to a limited degree. Owners are often referred to other resources for more complex investigations or solutions. Individuals complaining about residential indoor air quality problems are also referred to other resources for additional information. The Air Pollution Control Program has no regulations or enforcement policies regarding indoor air quality at this time. Complainants may be referred to other agencies like the Occupational Health and Safety Administration, if appropriate ...

Common cleaning products, disinfectants and air fresheners are creating a toxic environment at home. Try natural alternatives and live longer.. Toxic chemicals in the home impact our health, causing ailments that range from respiratory ailments to cancer. A US EPA study on indoor air quality found that the use of common cleaning products result in levels of several Volatile Organic Compounds (VOCs) that are on average two to five times higher indoors than outdoors. During (and for several hours immediately after) certain activities such as paint stripping, levels may be at 1,000 times the background outdoor levels. Natural non-polluting alternatives are available to replace many common cleaners and some products such as paints, paint strippers, and other solvent-based products. Solvents should be used with extreme caution and with adequate time and ventilation for the toxic chemicals to leave the indoor space before you go back into it.. ...

Humans spend most of their lives in indoor environments; hence, indoor exposure to air pollution may constitute a large part of the total exposure to air pollution. Polycyclic aromatic hydrocarbons are well known for their mutagenicity and carcinogenicity and are ubiquitous in urban environments as a result of combustion from e.g. vehicular traffic. Polycyclic aromatic hydrocarbons associated to air particulate matter in indoor environments originates from several sources including: cooking and heating, outdoor sources, smoking, candle and incense burning. Infiltration has been suspected to be one major source of indoor polycyclic aromatic hydrocarbons. In this study, four different air filter materials intended for mechanical ventilation were tested for their capability to remove particle bound polycyclic aromatic hydrocarbons and other genotoxic compounds from a real urban aerosol. Particles were sampled at two highly trafficked locations in Stockholm using a sampling system capable of sample ...

Abstract This study investigated the possible relationships between exposures to mite allergen and airborne fungi with sick building syndrome (SBS) symptoms for residents living in newly built dwellings. We randomly sampled 5709 newly built dwellings in six prefectures from northern to southern Japan. A total of 1479 residents in 425 households participated in the study by completing questionnaire surveys and agreeing to environmental monitoring for mite allergen (Der 1), airborne fungi, aldehydes, and volatile organic compounds. Stepwise logistic regression analyses adjusted for confounders were used to obtain odds ratios (OR) of mite allergen and fungi for SBS symptoms. Der 1 had a significantly high OR for nose symptoms. Rhodotorula had a significantly high OR for any symptoms, and Aspergillus had significantly high OR for eye symptoms. However, the total colony-forming units had a significantly low OR for throat and respiratory symptoms. Eurotium had a significantly low OR for skin symptoms. ...
Exposure to radon gas is the second most common cause of lung cancer after smoking. A large number of studies have reported that exposure to indoor radon, even at low concentrations, is associated with lung cancer in the general population. This paper reviewed studies from several countries to assess the attributable risk (AR) of lung cancer death due to indoor radon exposure and the effect of radon mitigation thereon. Worldwide, 3-20 % of all lung cancer deaths are likely caused by indoor radon exposure. These values tend to be higher in countries reporting high radon concentrations, which can depend on the estimation method. The estimated number of lung cancer deaths due to radon exposure in several countries varied from 150 to 40,477 annually. In general, the percent ARs were higher among never-smokers than among ever-smokers, whereas much more lung cancer deaths attributable to radon occurred among ever-smokers because of the higher rate of lung cancers among smokers. Regardless of smoking status,
