Hexavalent chromium [Cr(VI)] compounds are Group-I human carcinogens. Cr(VI)-induced DNA-protein crosslinks (DPCs) have been implicated in the mutagenic and carcinogenic effects of Cr(VI). Although multiple mechanisms have been suggested for Cr(VI)-induced DNA-protein crosslinking, the mechanism of formation of DNA-protein crosslinks
