Understanding Indoor Air Quality Issues

According the EPA, 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. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.

the primary causes of indoor air quality problems stem from indoor pollution sources that emit gases or particles into the air. Inadequate ventilation can exacerbate indoor pollutant levels by not introducing enough outdoor air to dilute emissions from indoor sources and failing to remove indoor air pollutants effectively. Additionally, elevated temperature and humidity levels can lead to higher concentrations of certain pollutants.

Identifying Sources of Pollutants

Numerous sources contribute to indoor air pollution, including:

The significance of each source depends on the amount and toxicity of pollutants emitted. Factors like the age and maintenance of a source can also be influential. For instance, a gas stove that is improperly adjusted can release substantially more carbon monoxide than a properly adjusted one.

Certain sources, such as building materials, furnishings, and air fresheners, can continuously release pollutants, while activities like smoking, cleaning, redecorating, or engaging in hobbies release pollutants intermittently. Improperly used or malfunctioning appliances can release high and potentially hazardous levels of pollutants indoors.

After certain activities, pollutant concentrations can linger in the air for extended periods.
