What did the EPA release in September 2010 about chromium?

On September 30, 2010, a draft human health assessment for chromium-6, was released by EPA's IRIS Program for independent expert peer review and public comment. This draft IRIS health assessment addresses both noncancer and cancer health effects associated with the ingestion of chromium-6 over a lifetime. This is the first EPA cancer assessment for hexavalent chromium (chromium-6) by ingestion. EPA worked in conjunction with the New Jersey Department of Environmental Protection, California Environmental Protection Agency, and Agency for Toxic Substances and Disease Registry on the development of this draft IRIS assessment and is using information from their recent draft assessments of hexavalent chromium (chromium-6) as the primary basis for the IRIS assessment. For a copy of the draft risk assessment and further information about its results, visit EPA?s Web site at: For more information on chromium, please visit our Web site at the following URL:
