Formaldehyde is a common indoor air pollutant found in virtually all homes and buildings. It is a colorless gas with a pungent odor, and at elevated levels is highly irritating to the eyes, nose, and lungs. Formaldehyde is released into the home from a variety of indoor sources, including plywood, particleboard, and other pressed wood products, and many consumer products. Several documents are available that summarize the health effects of formaldehyde and discuss ways to reduce your exposure to it.
