Formaldehyde has been classified as a probable human carcinogen. Indoor air quality measurements carried out worldwide in schools indicate that levels may be of concern. This paper provides an overview of emission sources, properties and methods for quantification of formaldehyde. Quantitative information from studies performed in school environments was compiled and a comprehensive picture of the causal relationships between pollutant exposures and children's health given. Mitigation actions to reduce formaldehyde levels and its adverse impacts in school buildings are recommended.
