Sources: Pressed wood products (hardwood plywood wall paneling, particleboard, fiberboard) and furniture made with pressed wood products, urea-formaldehyde foam insulation, combustion sources and environmental tobacco smoke, durable press drapes, some textiles, and glues.

Health Effects: Eye, nose, and throat irritation; wheezing and coughing; fatigue, skin rash and severe allergic reactions. May cause cancer. May also cause other effects listed under "organic gases."

Steps to Reduce Exposure:

• Use "exterior grade" pressed wood products (lower-emitting because they contain phenol resins, not urea resins).
• Use air conditioning and dehumidifiers to maintain moderate temperature and reduce humidity levels.
• Increase ventilation, particularly after bringing new sources of formaldehyde into the home.
• Insist on a carpet or carpet pad with little or no formaldehyde content.
