Define Chromium Toxicity?
Trivalent chromium, the form of chromium found in foods and supplements, is least toxic. Oral supplements upto 800 to 1000 mcg per day appear to be safe. However, hexavalent chromium often found in paints, welding fumes and other industrial settings is very toxic. Inhalation of Cr6+ may result in respiratory disease while direct contact results in dermatitis and skin ulceration. Liver damage can also occur.
