Formaldehyde Poisoning is a disorder brought about by breathing the fumes of formaldehyde. This can occur while working directly with formaldehyde, or using equipment cleaned with formaldehyde. Major symptoms may include eye, nose, and throat irritation; headaches; and/or skin rashes.
Formaldehyde is considered a toxic compound because of its ability to react with proteins, nucleic acids, and lipids. The World Health Organization has established an air quality guideline of 100 Î¼g m -3 for formaldehyde (European Commission, 1994).
