In April 2022, EPA publicly released the draft formaldehyde assessment for review and comment. The Toxicological Review and charge were reviewed internally by EPA and by other federal agencies and White House Offices before public release. Through the IRIS process, all written comments on IRIS assessments submitted by other federal agencies and White House Offices will be made publicly available. Accordingly, interagency comments and the interagency science consultation draft of the IRIS Toxicological Review of Formaldehyde-Inhalation are posted on this site.
