Air pollutants come from many sources. The most common indoor pollutants include radon, pet dander, mold, lead, asbestos, and ozone. (1) In addition, many standard cleaning products and building materials have the potential to release chemicals or other pollutants into the air around us. Without adequate airflow, the concentration of these pollutants can be high enough to affect health.
Allergies, headaches, nose and throat irritation, and the triggering of asthma attacks are a few known health effects related to indoor air pollution. Long-term consequences such as respiratory disease, heart disease, and cancer are also possible. (1)
As air pollution has increased, researchers have begun to look at impacts on brain function when exposed to polluted air, specifically in schools and workplaces. (2) The link between decreased performance at school and exposure to poor air quality is leading many schools to take steps to better manage indoor pollutants.
