Hazards of trivalent chromium and hexavalent chromium I am examining a material safety data sheet that reports on trivalent and hexavalent chromium in chemical films. It covers each type where it is used in a product individually.

Is there a practical difference in safety between the two, such that they should be reported separately?
Hexavalent chromium is a genotoxic carcinogen. Due to the similarity of the chromate(VI) and sulfate ions, it is transported around the body via the sulfate channels. Due to this it is a major health hazard. Trivalent chromium on the other hand is not generally regarded as a health hazard due to its poor solubility in water. With this information you should report both separately.
