Industry Says Pending Study Shows No Need To Strengthen EPA's Cr6 Limits

摘要

Industry-funded researchers say their soon-to-be published risk research shows that EPA's current drinking water limit for hexavalent chromium (Cr6) is adequately protective, bolstering chemical industry efforts to push EPA to soften its controversial 2010 draft assessment that labeled the metal a human carcinogen and was expected to drive stricter regulatory standards. The finding is likely to draw criticism from environmentalists, who have admonished EPA for delaying its assessment to allow industry time to complete its study.
