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)

Abstract Background: Globally, indoor air pollution from various forms of pollutants is an increasing problem. The most common form of indoor air pollution is that caused by inefficient burning of solid and fossil fuels like wood, charcoal and kerosene in indoor environments. Indoor air pollution is therefore a significant problem particularly in sub-Saharan Africa (SSA) including Uganda where use of such solid fuels is most common. There is however little attention drawn to understanding the problem specifically in Uganda to come up with tailor-made solutions. Objectives: To assess risk factors for indoor air pollution exposure in households in Bulamu ward, Kasangati town council, Wakiso district so as to provide information that could be used to make proper decisions and design measures to reduce indoor air pollution. Methodology: A cross sectional study was carried out among 96 households in Bulamu ward, Kasangati town council, Wakiso district. From the 5 villages within the ward, 1 was ...
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 ...
Indoor Air Pollutants. 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. However, reduced airflow in a building can cause air quality problems in three ways.. ...

Solutions to Indoor Air Pollution - One of the best solutions to indoor air pollution is ventilation. Learn more solutions to indoor air pollution and to breathing more easily.
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 ...
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. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air conditioner with ...

Maintaining indoor air quality has become a complicated challenge in todays world. In fact, in most cases we are our own worst enemy because many of the products we use are actually introducing toxins into the air we breathe! Every year, more people reporting lung disease, heart disease and other serious diseases due to exposure to airborne carcinogens.. In past decades, you might have thought you could get away from the toxins by going inside and shutting the door. But recent reports indicate our indoor air is now up to five times more toxic than our outdoor air.. This means the real fight to purify your air is going to take place indoors. One of the best ways to maintain good indoor air quality is to install the latest technology AC units such as ducted air conditioning Sydney.. In this post, meet nine of the most concerning airborne toxins and learn how to remove them from your indoor air supply. Some of the indoor air pollutants are discussed below:. ...
Most people think of their homes as a safe haven, a place where they are protected from pollutants and toxins. Unfortunately, that may not be true. Our homes are a host of unseen, airborne pollutants that can be a health hazard. According to World Health Organization, almost 40% of homes pose a serious health danger to the dwellers. The EPA says that indoor air pollution is of or major problems in America when it comes to health.. So what are the common indoor air pollutants? Most of the pollutants come with modern living.

Indoor air quality in schools may have an impact on students health and concentration, and activities for maintenance and improvement should be carried out on the basis of an objective evaluation of the indoor air quality. The purpose of this study is to suggest a method for setting the absolute and relative reference values for an indoor air quality index in the classrooms of the school. The pollutant concentration criteria in domestic and foreign codes, guidelines, certification systems, and indoor environment indexes were investigated and analyzed, and the absolute references with three levels were established for five pollutants including PM10, PM2.5, CO2, formaldehyde, and total airborne bacteria. The distribution characteristics of each pollutant were analyzed using the public data from the Ministry of Education, and peer groups for appropriate comparison were suggested for setting relative references. ...
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., ...
While clean indoor air legislation at the state level is an evidence-based recommendation, only limited evidence exists regarding the impact of clean indoor air policies on state smoking prevalence. Using state smoking prevalence data from 1997 to 2010, a repeated measures observational analysis assessed the association between clean indoor air policies (i.e., workplace, restaurant, and bar) and state smoking prevalence while controlling for state cigarette taxes and year. The impacts from the number of previous years with any clean indoor air policy, the number of policies newly in effect during the current year, and the number of policies in effect the previous year were analyzed. Findings indicate a smoking prevalence predicted decrease of 0.13 percentage points (p = 0.03) for each additional year one or more clean indoor air policies were in effect, a predicted decrease of 0.12 percentage points (p = 0.09) for each policy newly in effect in the current year, and a predicted decrease of 0.22 ...
Indoor air quality 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.. ...
Did you know that the air you breathe inside your house can be polluted, too? Several things in your home contribute to indoor air pollution. This article tells you about the sources of indoor air pollution and gives you tips on how to eliminate them.
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 ...

Indoor Pollutants Linked to Asthma Symptoms in Children About one out of five Americans suffers from allergies. An allergy is an exaggerated response from the immune system to a substance such as dust, pollen, pet dander or mold.
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 ...

However, existing studies demonstrated that various air pollutants are found in classrooms, sometimes at elevated concentrations. Data also indicated that poor air quality may impact childrens health, in particular respiratory health, attendance, and academic performance. Nevertheless, it should be noted that there are other adverse health effects that are less documented. Few data exist for teachers and other adults that work in schools. Allergic individuals seem to be at a higher risk for adverse respiratory health consequences. Air quality improvement represents an important measure for prevention of ...
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 ...

March 2005. Abstract. In many rural areas of low-income countries, biomass fuel is the principal source of household energy, meaning that indoor air pollution (IAP) is a serious health problem. If exposure to IAP is greatest in areas where combustion occurs, primarily the kitchen, IAP will mostly affect the women who cook and the children whom they supervise. Using a 2000-2003 survey of 1638 rural households in Bangladesh, where biomass fuel provides more than 90 percent of household energy, we investigate (i) the extent to which the division of household responsibilities, household structure, and dimensions and location of kitchen facilities causally affect the health of women and children, taking into account optimizing behavior within households, and (ii) whether households act as if they are optimally sharing the burden of a disease. The results suggest that proximity to stoves adversely affects the respiratory health of women and the young children they supervise and that households appear ...

Exposure to air pollution has been linked to elevated blood pressure (BP) and hypertension, but most research has focused on short-term (hours, days, or months) exposures at relatively low concentrations. We examined the associations between long-term (3-year average) concentrations of outdoor PM and household air pollution (HAP) from cooking with solid fuels with BP and hypertension in the Prospective Urban and Rural Epidemiology (PURE) study. Outdoor PM exposures were estimated at year of enrollment for 137,809 adults aged 35-70 years from 640 urban and rural communities in 21 countries using satellite and ground-based methods. Primary use of solid fuel for cooking was used as an indicator of HAP exposure, with analyses restricted to rural participants (n = 43,313) in 27 study centers in 10 countries. BP was measured following a standardized procedure and associations with air pollution examined with mixed-effect regression models, after adjustment for a comprehensive set of potential ...

Indoor Air Quality (IAQ) problems are not limited to just homes. In fact, many office buildings have a wider variety of air pollution sources, such as office equipment, printing/copying, and industrial chemicals. Some of these buildings may be inadequately ventilated or mechanical ventilation systems may not be designed or operated to provide adequate amounts of outdoor air. In addition, sometimes external sources of pollutants like wildfires are beyond our control and systems are not adequately designed to handle these extreme cases. Finally, people generally have less control over the indoor environment in their offices than they do in their homes. As a result, there has been an increase in the incidence of reported health problems due to poor indoor air quality, which impacts employee productivity.. Examples of office air pollutants include gases and particles produced by tobacco smoking, those released by molds and bacteria that grow indoors on damp surfaces, and the volatile organic ...

AirRenew Essential Indoor Air Quality Drywall improves indoor air quality by capturing and converting formaldehyde into a safe, inert compound
Any type of building or home can have issues related to IAQ. New homes, offices, and schools are built to be tight and solid in order to conserve energy. This can lead to inadequate ventilation and less ventilation may lead to higher concentrations of indoor pollutants. Owners of existing buildings and homeowners are attempting to increase energy-saving and decrease heating and cooling costs by installing storm windows and insulation, caulking and weather stripping, and heating through natural resources. All buildings and homes need regular maintenance as they age. Paint and caulking deteriorate, pipes break, roofs leak, and so on, which can lead to problems with indoor air quality.. Indoor pollutants may cause discomfort and illness. People with lung problems, such as asthma or emphysema, are the most sensitive and may become affected before an otherwise healthy person would even notice there was a problem. At extreme levels, they can even be fatal. IAQ pollutants have many sources and may ...

We can add things to water that are good, but may be enhance the health benefits ... like sugar or carbonation. And, we can make tea, coffee, and additives our bodies might like.
Elevated indoor air pollution levels due to the burning of biomass in developing countries are well established. Few studies have quantitatively assessed air pollution levels of improved cookstoves and examined these measures in relation to health effects. We conducted a cross-sectional survey among 79 Honduran women cooking with traditional or improved cookstoves. Carbon monoxide and fine particulate matter (PM2.5) levels were assessed via indoor and personal monitoring. Pulmonary function and respiratory symptoms were ascertained. Finger-stick blood spot samples were collected to measure C-reactive protein (CRP) concentrations. The use of improved stoves was associated with 63% lower levels of personal PM2.5, 73% lower levels of indoor PM2.5, and 87% lower levels of indoor carbon monoxide as compared to traditional stoves. Women using traditional stoves reported symptoms more frequently than those using improved stoves. There was no evidence of associations between cookstove type or air ...
Pursuant to a congressional request, GAO provided information on the federal and state actions that have been taken to address indoor air quality concerns that have been raised by occupants of certain school, state, and federal buildings in Vermont, the District of Columbia, and Maryland, focusing on: (1) the extent to which the Environmental Protection Agency (EPA) and other federal agencies have been involved in investigating, evaluating, and mitigating the indoor air problems of 15 specified buildings in Vermont and, if there has been little or no direct federal involvement, identify the reasons and other forms of federal assistance, if any, that have been provided; (2) the role of the nonfederal organizations that have acted to address the indoor air quality problems of the buildings; (3) the indoor quality problems in these buildings and the steps that have been taken or that are needed to deal with them; and (4) the actions taken by federal agencies to address air quality problems in EPAs ...
Indoor air pollutants in homes, buildings, and schools can negatively impact the health of occupants. Some pollutants cause health problems such as eye irritation, burning in the nose and throat, headaches or fatigue. Others can worsen allergies, respiratory illnesses (such as asthma) or even cause cancer (from radon gas). Exposure to unhealthy indoor air pollutants in homes, buildings, and schools can be reduced through better design, construction, operational and maintenance practices; personal choices; and mitigation of indoor air quality problems. ...
A third of the worlds population use plant-based solid fuels such as wood or charcoal, or coal, to cook, heat, and light their homes, primarily in Asia and Africa. These smoky, dirty fuels are often used in an open fire or simple stove, resulting in high levels of household air pollution in poorly ventilated homes.. Studies in India have found that in some areas, household air pollution is so high that it actually increases outdoor (ambient) air pollution - leading to pollution levels more than three times higher than a typical London street, and well above WHO-recommended safety levels.. The Commission, which was led by Professor Stephen Gordon, from the Liverpool School of Tropical Medicine, UK, and Professor William Martin, from The Ohio State University, USA, examines evidence for the effects of household air pollution on health. They conclude that an estimated 600-800 million families worldwide are at increased risk of illnesses such as respiratory tract infections, pneumonia, COPD, ...
When people think about air pollution, they usually picture vehicle exhaust or factory emissions. But the air in your home can be up to three times more polluted than the air outside. Sometimes, people can smell something is off. The homes air is stuffy, stale or musty. Sometimes, people can see the problem, such as when mold is growing on a wall or ceiling.Other times, people suffer a range of health issues such as headaches, dizziness, nausea, fatigue and flu-like symptoms but are at a loss to explain why they feel so badly. They are simply desperate to make their symptoms stop. These people may be suffering from sick building syndrome caused by poor indoor air quality. They may suspect but havent been able to confirm that their home is making them sick.. Adverse health conditions caused by poor indoor air quality range from mild discomfort such as symptoms associated with the common cold to major illnesses such as cancer or respiratory disease. Symptoms may show up quickly or many years ...

FRIDAY, Dec. 13, 2019 (HealthDay News) -- Toddlers have an increased risk of allergies if they are exposed to multiple indoor pollutants in their first years of life, a new study finds.. It included 108 mother-child pairs. Researchers assessed exposures to various household pollutants such as pet dander and tobacco smoke while the women were pregnant, then when children were aged 6 months, 1 year and 2 years.. A skin prick test was performed on both the mothers and their children when they were 2 to measure allergic sensitivity. The study was published recently in the journal Annals of Allergy, Asthma and Immunology.. Because most children are exposed to more than one pollutant or allergen, we examined the relationship between multiple exposures and allergic sensitizations at 2 years of age, said study co-author Mallory Gallant, from the Department of Biomedical and Molecular Sciences at Queens University in Kingston, Ontario, Canada.. We examined exposure to dogs, cats, air fresheners, ...

Berkeley Air researchers conducted a study in Ciudadela de San Martin, Nicaragua, to evaluate the efficacy and effectiveness of two models of the EcoStove (or Ecofogon) - one fully open and one semi-closed - in reducing indoor air pollution (IAP). Using a randomized stove intervention trial, we evaluated the influence of stove type on kitchen air pollution levels and womens exposures to fine particulate matter.. Adjusting for the effects of study group, duration of cooking, burning trash, and average daily temperature, introduction of the closed EcoStove was associated with an 86% reduction in PM2.5 exposure, while the introduction of the semi-open model was associated with an 80% reduction (the difference was not significant). The two EcoStove models did have significantly different effects on kitchen levels of PM2.5 (p-value = 0.028), with the closed EcoStove reducing kitchen PM2.5 levels by 94% and the semi-open EcoStove reducing kitchen PM2.5 levels by 87%.. The magnitude of the exposure ...
Just like outdoor air pollution, indoor air pollution can pose a risk to health. As we spend much time in our homes, it is important that the air is as clean as possible.

Do you work in office building? Chances are that you do, and chances are that you suffer from poor indoor air quality. With allergens, pollen and mold spores making their way into your office building, it is important to learn the easy ways you can improve the air that you breathe for most of the day.. Indoor air quality has a significant effect on your ability to breathe clearly at work. Poor indoor air quality can increase your risk of illness and lead to serious health problems. Fixing and maintaining good office indoor air quality involves many factors, including, Maintaining good indoor air quality requires attention to the buildings heating, ventilation, and air conditioning (HVAC) system; as the EPA outlined, it also includes, the design and layout of the space; and pollutant source management. (EPA.gov). Here are easy steps you and your office can take, to improve your office air quality:. 1) Do not block air vents: Make sure that your HVAC systems vents are clear from boxes or ...
Contaminants in indoor air resulting from vapor intrusion are often estimated using the concentrations in a sub-slab sample multiplied by an attenuation factor (AF). An AF accounts for the reduction in concentration that occurs when vapors enter a building and mix with indoor air. The Minnesota Pollution Control Agency (MPCA) is using a very protective AF of 0.1, (or 10% of the soil vapor found in the sub-slab will be in indoor air). The amount of soil vapor that enters a building is different for every building, but this AF overestimates indoor air concentrations in most homes.. EPA recently recommended an AF of 0.03 for screening sub-slab soil vapor at vapor intrusion sites throughout the U.S. (USEPA, 2015). EPA derived the AF of 0.03 after looking at data from numerous homes across the country. 95 percent of the homes studied had (basement) indoor air concentrations less than or equal to 0.03 times the sub-slab concentration, and 50 percent of the homes had (basement) indoor air ...
The review focuses on strategies for assessing the toxicology of indoor air pollutant mixtures. These strategies are illustrated by reviewing the current problems and approaches to the toxicology of indoor air pollutants from three indoor source categories which make a major contribution to human exposure: environmental tobacco smoke, combustion emissions, and volatile organic compound (VOC) mixtures from materials and products. The strategies include assessment of: exposure and dosimetry, toxic effects of mixtures, causative agents in mixtures, and the predictability of toxicology from one mixture to another. Case studies from indoor air pollution are used to illustrate these strategies. Environmental tobacco smoke research on exposure and dosimetry illustrates new methods using biological markers. Unvented combustion sources such as kerosene heaters emit genotoxic incomplete combustion products and recent research is focused on identifying the genotoxic (causative) agents in these mixtures ...
A study of air pollution levels in Kenyan slum households show that levels are especially high in homes using wood and kerosene as cooking fuels. But despite the high levels of harmful fine particles within their houses, residents perceive indoor air quality to be better than that found outdoors, and say that they are used to the situation. Imperfect knowledge among study participants about the adverse health effects of air pollution contribute to practices that worsen air quality, according to a doctoral thesis from Umeå University.
Portable air cleaners generally contain a fan to circulate the air and use one or more of the air cleaning devices discussed above. Portable air cleaners may be moved from room to room and used when continuous and localized air cleaning is needed. They may be an option if a home is not equipped with a central HVAC system or forced air heating system.. Portable air cleaners can be evaluated by their effectiveness in reducing airborne pollutants. This effectiveness is measured by the clean air delivery rate, or CADR, developed by the Association of Home Appliance Manufacturers, or AHAM. The CADR is a measure of a portable air cleaners delivery of contaminant-free air, expressed in cubic feet per minute. For example, if an air cleaner has a CADR of 250 for dust particles, it may reduce dust particle levels to the same concentration as would be achieved by adding 250 cubic feet of clean air each minute. While a portable air cleaner may not achieve its rated CADR under all circumstances, the CADR ...
BACKGROUND: Exhaled carbon monoxide (COex) level is positively associated with tobacco smoking and exposure to smoke from biomass/coal burning. Relatively little is known about its determinants in China despite the population having a high prevalence of smoking and use of biomass/coal. METHODS: The China Kadoorie Biobank includes 512,000 participants aged 30-79 years recruited from 10 diverse regions. We used linear regression and logistic regression methods to assess the associations of COex level with smoking, exposures to indoor household air pollution and prevalent chronic respiratory conditions among never smokers, both overall and by seasons, regions and smoking status. RESULTS: The overall COex level (ppm) was much higher in current smokers than in never smokers (men: 11.5 vs 3.7; women: 9.3 vs 3.2). Among current smokers, it was higher among those who smoked more and inhaled more deeply. Among never smokers, mean COex was positively associated with levels of exposures to passive smoking and to
According to the US Environmental Protection Agency, most Americans spend as much as 90% of their time indoors. However, the air indoors can have up to five times more pollutants in comparison to the air outdoors. Of course, the former can be a great health hazard. The good news is it is not exactly difficult to improve indoor air quality. Here are some simple ways to achieve that goal. Clean Dehumidifiers and Air Conditioners. Most houses in the US have air conditioners and dehumidifies. Over time, dust particles and other air contaminants will clog them and consequently compromise the quality of air you breathe. For adults and children allergic to dust, fresh air indoors can make a huge difference. Hire a professional HVAC technician to clean your air conditioners and humidifiers regularly. Ventilate. During the summer, it is wise to open the windows to let fresh air circulate in your home. This will also help control humidity. Take note high levels of humidity tend to encourage mold growth as ...
Hazards in our indoor environments have been recognized since biblical times. The advice in Leviticus 14:33-48 for treating mold infested houses has contemporary meaning in the recent World Health Organization (WHO) document on damp and moldy indoor spaces [1]. In the developed world, faulty combustion, carbon monoxide from coal gas, lead paint, poor ventilation of tenement housing and hospitals have been recognized for decades as unhealthy. Indoor air quality, however, was not appreciated as an important component of public health until the proliferation of sealed buildings, energy conservation programs (urea formaldehyde foam insulation), new products, and the recognition of the health effects of radon, asbestos and latex.

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 ...
Until rather recently, the emphasis on air quality evaluation has been centred upon the outdoor environment, namely on studies regarding behaviour, effects and outdoor air pollutants prediction [1-5] and it has been reported that outdoor pollution, specifically nitrogen dioxide (NO2), particulate matter with an aerodynamic diameter equal or smaller than 10 μm (PM10) and ozone (O3), causes an increase on asthma prevalence and also on its severity, having worst effects on children [6-11]. It is now known that IAP likely has equal or even greater impact on childrens health when compared to that of outdoor pollutants. This occurs because time spent indoor is usually higher than time spent outdoor; also, there is a great variety of indoor sources, that include outdoor and specific indoor sources associated with formaldehyde and volatile organic compounds (VOC) emissions, leading frequently to higher concentration than outdoor [12-14]. The World Health Organization (WHO) has assessed the ...

Forced air furnaces and central air conditioning systems share the annual temperature control workload. Both the heating and cooling units rely on the ductwork to carry conditioned air to the various rooms. The ducts are the lungs of the HVAC system. They directly impact comfort, energy efficiency and indoor air quality. If you consider the dust that builds up on surfaces in the home and contaminants that become trapped in the HVAC air filter, it stands to reason that the duct system is also at risk of an accumulation of debris. Things like dust, pollen, pet dander, construction debris, bugs, webs and even decomposing rodents are some of the unpleasant surprises found inside the average duct system. Theres also the possibility of mold and mildew growth. Every time the furnace or air conditioner starts up, air passes through this network of pipes. Any harmful spores, bacteria or toxins are then picked up, spread throughout the home and breathed by occupants. A long list of severe health concerns ...

ABSTRACT Mobile air cleaners have been gaining popularity as potentially effective tools for improving indoor air quality. Usually, the efficacy of an air cleaner is quantified by determination of the clean air delivery rate (CADR) under strictly defined conditions within test chambers lacking furniture and featuring adequate and homogeneous mixing of the test aerosol. By contrast, real-world scenarios may considerably differ from these conditions, resulting in adverse consequences, as a less homogeneous distribution of the cleaned air may produce spatial differences in the CADR and lead to lower overall efficacy for the air cleaner. Therefore, in this study, the spatial variance of a mobile air purifiers cleaning efficacy across several positions in a furnished and in-use office room was investigated for four different scenarios, in each of which the air cleaner was placed in a different position inside the room. Ambient outdoor air was supplied as target aerosol by opening a window prior to the
Those who usually undergo the most from the effects of poor air quality are the ones who remain indoors the most. This consists of the very young, individuals who are chronically ill, and people in the elderly population. Most of the time, removing the person from the area or getting rid of the cause of the air pollution can turnaround for the discomfort that the person is feeling, but in other cases contact with contaminated air can result in devastating illnesses. Poor quality air can be particularly hazardous to the people struggling with respiratory illnesses or cardiovascular disease.. There are many factors which affect the quality of indoor air. These could include uneven temperatures, poor ventilation and air flow, mold and fungi, a high level of pollutants as well as other suspended particulate contaminants. Thus, fresh air, adequate sunlight, good ventilation systems, and controlled humidity may dramatically bring about a healthy working place at any workplace. Oftentimes, odor control ...
There is no standard measurement for the effectiveness of UVGI cleaners. Typical UVGI cleaners used in homes have limited effectiveness in killing bacteria and molds. Effective destruction of some viruses and most mold and bacterial spores usually requires much higher UV exposure than is provided in a typical home unit. Furthermore, dead mold spores can still produce allergic reactions, so UVGI cleaners may not be effective in reducing allergy and asthma symptoms.. There is no standard measurement for the effectiveness of PCO cleaners. The use of PCO cleaners in homes is limited because currently available catalysts are ineffective in destroying gaseous pollutants from indoor air. Some PCO cleaners fail to destroy pollutants completely and instead produce new indoor pollutants that may cause irritation of the eyes, throat, and nose.. Portable Air Cleaners. Portable air cleaners generally contain a fan to circulate the air and use one or more of the air cleaning devices discussed above. Portable ...

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..

Most of us tend to think of air pollution as something that occurs outdoors where car exhaust and factory fumes proliferate, but theres such a thing as indoor air pollution, too. Since the 1950s, the number of synthetic chemicals used in home products have increased drastically, while homes have become much tighter and better insulated. As a result, the EPA estimates that Americans, on average, spend approximately 90 percent of their time indoors, where the concentrations of some pollutants are often two to five times higher than typical outdoor concentrations. Luckily, there are many ways to reduce indoor air pollution. We all know that buying organic and natural home materials and cleaning supplies can improve the air quality in our homes, but there are several other measures you can take as well. How pollutants get into our homes Potentially toxic ingredients are found in many materials throughout the home, and they leach out into the air as Volatile Organic Compounds, or VOCs. If you open a ...

Volatile organic compounds are chemicals used to manufacture and maintain building materials, interior furnishing, cleaning products and personal care products. Volatile means that these chemicals evaporate or can easily get into the air at room temperature. Organic means these chemicals are carbon based. The term chemical emissions refers to VOCs as they evaporate into the air from products.. Studies by the EPA and other researchers from the New York Department of Health, have found that VOCs are common in indoor environments and that their levels may be two to a thousand times higher than outdoors. There may be anywhere from 50 to hundreds of individual VOCs in the indoor air at any one time. Some may produce objectionable odors at very low levels, but many have no noticeable smell.. ...
