Top of Page Primary Causes of Indoor Air Problems Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems.
Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened.
EPA provides guidance as to risks associated with different levels of exposure and when the public should consider corrective action. Such immediate effects are usually short-term and treatable. While weatherization is underway, however, steps should also be taken to minimize pollution from sources inside the home.
People also react very differently to exposure to indoor air pollutants. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.
Inexpensive devices are available for measuring radon. If the symptoms fade or go away when a person is away from the area, for example, an effort should be made to identify indoor air sources that may be possible causes.
Weatherization generally does not cause indoor air problems by adding new pollutants to the air. These factors include poor ventilation lack of outside airproblems controlling temperature, high or low humidity, recent remodeling, and other activities in or near a building that can affect the fresh air coming into the building.
The right ventilation and building care can prevent and fix IAQ problems. You may also want to consult a board-certified allergist or an occupational medicine specialist for answers to your questions.
If you think that you have symptoms that may be related to your home environment, discuss them with your doctor or your local health department to see if they could be caused by indoor air pollution.
Certain immediate effects are similar to those from colds or other viral diseases, so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue.
Although the presence of such sources does not necessarily mean that you have an indoor air quality problem, being aware of the type and number of potential sources is an important step toward assessing the air quality in your home. Further research is needed to better understand which health effects occur after exposure to the average pollutant concentrations found in homes and which occurs from the higher concentrations that occur for short periods of time.
The General Duty Clause of the OSH Act the law that created OSHA requires employers to provide workers with a safe workplace that does not have any known hazards that cause or are likely to cause death or serious injury.
For this reason, it is important to pay attention to the time and place symptoms occur. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.
Also, some specific diseases have been linked to specific air contaminants or indoor environments, like asthma with damp indoor environments. However, measures such as installing storm windows, weather stripping, caulking, and blown-in wall insulation can reduce the amount of outdoor air infiltrating into a home.
A third way to decide whether your home may have poor indoor air quality is to look at your lifestyle and activities. Poor indoor air quality IAQ has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs.
Weatherizing Your Home Some health effects can be useful indicators of an indoor air quality problem, especially if they appear after a person moves to a new residence, remodels or refurnishes a home, or treats a home with pesticides. Additional weatherization measures should not be undertaken until these problems have been corrected.
Identifying Problems in the Indoor Environments Long-Term Effects Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. Consequently, after weatherization, concentrations of indoor air pollutants from sources inside the home can increase.
Deteriorated asbestos-containing insulation Newly installed flooring, upholstery or carpet Cabinetry or furniture made of certain pressed wood products Products for household cleaning and maintenance, personal care, or hobbies Central heating and cooling systems and humidification devices Excess moisture.
Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later. The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and preexisting medical conditions.
In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Without measurements there is no way to tell whether radon is present because it is a colorless, odorless, radioactive gas.
Testing for many pollutants can be expensive. Glossary Indoor Air Pollution and Health Indoor Air Quality IAQ refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.
Many factors affect IAQ. High temperature and humidity levels can also increase concentrations of some pollutants.1 Na Li Indoor Air Quality (IAQ) Using Temporal Data and GIS to Visualize IAQ in Campus Buildings Bachelor’s Thesis Environmental Engineering.
