Comments

CrVI compounds are irritants, sensitizers, and may be corrosive to the skin. CrVI compounds are respiratory tract irritants and may cause pulmonary sensitization. CrVI may cause acute tubular necrosis and liver injury. [ATSDR Case Studies] Calcium chromate is approximately 10 times more potent than zinc chromate as an animal carcinogen by intrabronchial implantation. [ACGIH] Skin contact may cause dermatitis and ulcers; [CHRIS] Very toxic by ingestion; Not soluble in water; [CAMEO] See "Chromium" and linked occupational diseases.
