Worried about the safety of your drinking water? Here's another reason to worry: A new report shows high levels of the cancer-causing chemical hexavalent chromium (chromium-6) in 89 percent of cities sampled. The toxin has been linked to stomach cancer and other gastrointestinal tumors.
Hexavalent chromium (chromium VI) refers to chemical compounds that contain the element chromium in the +6 oxidation state. Virtually all chromium ore is processed via hexavalent chromium, specifically the salt sodium dichromate. Approximately 136,000,000 kilograms (300,000,000 lb) of hexavalent chromium were produced in 1985. Other hexavalent chromium compounds are chromium trioxide and various salts of chromate and dichromate. Hexavalent chromium is used for the production of stainless steel, textile dyes, wood preservation, leather tanning, and as anti-corrosion and conversion coatings as well as a variety of niche uses.
