Hexavalent chromium (chromium(VI), Cr(VI), chromium 6) is any chemical compound that contains the element in the +6 oxidation state (thus hexavalent).[1] It has been identified as carcinogenic, which is of concern since approximately 136,000 tonnes (150,000 tons) of hexavalent chromium were produced in 1985.[2] Hexavalent chromium compounds can be carcinogens (IARC Group 1), especially if airborne and inhaled where they can cause lung cancer.
