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

Adsorption thermodynamic characteristic and kinetics of dissolved chromium from aqueous solutions onto humic acids (HAs) were studied. The results showed that the Freundlich isotherm model described the equilibrium data well. The negative DeltaG degrees confirmed the spontaneity of adsorption process.
