Indoor Air Quality

Contact Information: Deb Kilbarger, Food Safety Team Leader - 740.652.2800


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 more information about a smoke free home, please go to ODH's tobacco use prevention page: Tobacco Use Prevention
