On May 3, 2013, the Toxicological Review of Methanol (noncancer) (Revised External Review Draft) was posted for public review and comment. Subsequently, the draft Toxicological Review, Appendices, and draft IRIS Summary were reviewed internally by EPA and by other federal agencies and the Executive Office of the President prior to final posting of the assessment on the IRIS database. Based on the 2009 IRIS assessment development process, all written comments on IRIS assessments submitted by other federal agencies and the Executive Office of the President will be made publicly available. Accordingly, interagency comments with EPA's response and the interagency science discussion draft of the IRIS Toxicological Review of Methanol (noncancer) and the draft IRIS Summary are posted on this site.

Methanol is a high production volume chemical with many commercial uses. It is a basic building block for numerous chemicals. Many of its derivatives are used in the construction, housing or automotive industries. Consumer products that contain methanol include varnishes, shellacs, paints, windshield washer fluid, antifreeze, adhesives, and deicers. This draft IRIS health assessment addresses non-cancer human health effects that may result from chronic exposure to this chemical. This draft assessment provides an inhalation reference concentration (RfC) for chronic non-cancer health effects and a reassessment of the oral reference dose (RfD).
