| Toxicity: |
Elemental chromium and certain chromium compounds
have been designated as carcinogens, hazardous substances,
hazardous waste constituents, and priority toxic
pollutants. Some of those compounds designated as hazardous
are chromic acetate, chromic acid, chromic sulfate, and chromous
chloride. Although chromium in
the 6+ state is regarded as being the most carcinogenic, there
are 6+ compounds that appear to be non-carcinogenic. In addition
to their possible carcinogenicity, chromium compounds
may have local allergic effects leading to dermatitis.
Systemically, 6+ chromium compounds are irritants to the
respiratory system and may give rise to pulmonary edema. |
