    OverviewEpidemiologyIndustryHexavalent chromium [Cr(VI)] is one of the valence states (+6) of the element chromium. It is usually produced by an industrial process. Cr(VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. Chromium metal is added to alloy steel to increase hardenability and corrosion resistance. A major source of worker exposure to Cr(VI) occurs during \"hot work\" such as welding on stainless steel and other alloy steels containing chromium metal. Cr(VI) compounds may b
