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. However, reduced airflow in a building can cause air quality problems in three ways.. ...

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:. ...

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., ...
... 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.. ...
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 ...
How to improve indoor air quality? Indoor air quality can be worse than outdoor and the pollutants can be grouped into three categories: gaseous, particulate, and biological. Here are some tips on improving indoor air quality where you live and work.

... 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 ...

N2 - Good indoor air quality in schools is important to provide a safe, healthy, productive, and comfortable environment for students, teachers, and other school staff. However, existing studies demonstrated that various air pollutants are found in classrooms, sometimes at elevated concentrations. Data also indicated that poor air quality may impact 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 ...
In October 2012, the National Institutes of Health (NIH) convened a Research Training Institute on Household Air Pollution on the NIH campus in Bethesda, Maryland. The three-day training workshop aimed to develop expertise in indoor air pollution research.

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 ...

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 ...
Indoor air pollution poses many challenges to the health professional. When you just ended your home decoration, there are a large number of toxic gases in your home. Formaldehyde is the most dangerous one. Formaldehyde is a very common chemical and can be found in everywhere.

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 ...
Human health has been identified to be affected more significantly by indoor air quality. Among numerous pollutants present in indoor air, formaldehyde (FA) is of great concern because of its highly hazardous nature. The concentrations of FA were determined from 20 newly decorated homes in the city of Gonabad, Iran during 2015. It was found that the indoor air levels of FA in all the sampled houses were exceptionally high in the range of 21 to 360 µg/m3 (mean of 149.3 µg/m3). If the 24-h average concentrations of FA measured from those sites were concerned, nearly 40% of them were seen to exceed the WHO guideline values (i.e., 100 µg/m3). One of the important reasons for the high concentrations could be low air exchange rates in those houses (e.g., from 0.18 to 0.37 h−1), high levels of humidity in the newly decorating houses and stronger sources in the indoor environment. Furthermore, its pollution in homes with natural ventilation was seen to be much higher than those of mechanical ...
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
