The major sources of indoor air pollution include:
- Environmental Tobacco Smoke (ETS)
- Carbon Monoxide (CO)
- Nitrogen Dioxide
- Organic Gases
- Respirable Particles
The relative importance of any single source depends on how much of a given pollutant it emits and how hazardous those emissions are. In some cases, factors such as how old the source is and whether it is properly maintained are significant. For example, an improperly adjusted gas stove can emit significantly more carbon monoxide than one that is properly adjusted.
The Environmental Protection Agency publishes a booklet that outlines the sources, health effects, levels in homes and steps to reduce exposure for each of the major causes of indoor air pollution.”The Inside Story: A Guide to Indoor Air Quality” is online at http://www.epa.gov/iaq/pubs/insidest.html
