There are many sources of indoor air pollution. High temperature and humidity levels can also increase concentrations of some 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. Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. 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. People also react very differently to exposure to indoor air pollutants. While pollutants commonly found in indoor air can cause many harmful effects, there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. Some effects may be made worse by an inadequate supply of outdoor air coming indoors or from the heating, cooling or humidity conditions prevalent indoors. 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. For this reason, it is important to pay attention to the time and place symptoms occur. Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures.Ĭertain 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. In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and preexisting medical conditions. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened. Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. Such immediate effects are usually short-term and treatable. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. 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.
