Formaldehyde is a colorless gas used as a preservative and disinfectant in the building industry, and in the manufacture of polymers. Formaldehyde is carcinogenic, irritates the eyes, nose, and lungs, and is known to react with other atmospheric chemicals to produce the deadly toxin carbon monoxide. Formaldehyde is used in some paints and adhesives, in some fabric treatments, and, significantly, in the manufacture of polymeric binding resins used in a wide variety of building products.
