NOTE: The IRIS Toxicological Review of Methanol (external review draft; December 2009) was released for public comment and external peer review in January 2010 (Federal Register Notice Jan 12, 2010). The draft assessment was placed on hold in June 2010 (Press Release Announcement Jun 15, 2010) pending a review of certain underlying cancer studies. The non-cancer portion of the draft assessment was not impacted by the review of the cancer studies and was subsequently re-released for public comment and external peer review (Press Release Announcement Apr 11, 2011). The non-cancer methanol assessment peer review panel met in July 2011 and that panel’s report is available. The original draft assessment (December 2009) has been archived but is available on this web page for the sake of transparency.
In March 2012 EPA announced that it would no longer rely on certain data (Ramazzini update) that were utilized in the December 2009 draft assessment to characterize the carcinogenic potential of methanol. The timeline for the development and completion of the revised methanol cancer assessment will be available on IRIS Track in the near future.
