Definition

Formaldehyde (HCHO), a colorless, pungent, carcinogenic, and toxic gas which can irritate membranes and may increase risk of developing brain cancer. It is used chiefly as a disinfectant and preservative.
Formaldehyde is an indicator of anthropogenic pollution and biomass burning. In the atmosphere Formaldehyde is produced when Methane reacts with atmospheric hydroxyl (OH) in the troposphere. Formaldehyde is removed from the atmosphere by its photolysis (a major source of free radicals in the atmosphere) or by reaction with atmospheric hydroxyl (OH).
