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 quothot workquot such as welding on stainless steel and other alloy steels containing chromium metal. Cr VI compounds may b
