Indoor Air Quality

People spend much of their time indoors, with much of this being in the home. However the air in your home can contain a variety of pollutants such as chemicals. In some cases levels in the home can become high enough to increase your family's risk of health effects. Common indoor air pollutants include:
  • Pesticides
  • Mold
  • Lead
  • Deteriorated Asbestos-Containing Insulation
  • Tobacco Smoke
Remember! The relative importance of any single source depends on how much of a given pollutant it emits and how hazardous those emissions are. For more information about indoor air quality issues, visit the EPA website at
