Our observations about the cytotoxic and cytogenetic effects of hexavalent and trivalent chromium compounds in mammalian cells cultured in vitro are reviewed. Additional data concerning the induction of chromosomal aberrations and sister chromatid exchanges, the inhibition of nucleic acid and protein synthesis, the interference with nucleotide metabolism, and the modification of membrane-linked enzyme activity are reported. A possible mechanism of chromium action is proposed.

Abstract
Our observations about the cytotoxic and cytogenetic effects of hexavalent and trivalent chromium compounds in mammalian cells cultured in vitro are reviewed. Additional data concerning the induction of chromosomal aberrations and sister chromatid exchanges, the inhibition of nucleic acid and protein synthesis, the interference with nucleotide metabolism, and the modification of membrane-linked enzyme activity are reported. A possible mechanism of chromium action is proposed.
