Studies by the US EPA show indoor air pollution to
be one of the top five environmental problems in
public health today. According to some studies, levels of
pollutants indoors can be 2-100 times higher than outdoors.
Since most people spend up to 90% of their time indoors, indoor
air quality is an important part of public health.
Indoor pollution sources that release gases or particles into
the air are the primary cause of indoor air quality problems in
homes. 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 home. High temperature and humidity levels
can also increase concentrations of some pollutants.
Pollutant sources can include combustion sources (i.e. gas,
kerosene, coal, wood or tobacco products), mold and moisture,
household cleaning products, and radon, amongst many others.
The relevance of these pollutants depends on the amount of the
pollutant emitted into the indoor environment.
Some pollutant sources continuously release pollutants (i.e. air
fresheners, building materials, etc.). Other sources,
related to daily activity, release pollutants intermittently in
the home. Intermittent sources include smoking, the use of
unvented or malfunctioning stoves, furnaces, or space heaters, and
the use of cleaning products and pesticides in housekeeping. For
