5200 |a"Great Lakes water quality reports indicate that sediment loadings of chromium exceed MOE guidelines for Lake Superior, Lake Ontario and Lake Huron. These findings confirm that chromium compounds are widespread, widely used and will continue to be a potential health problem of unknown magnitude. This study examined the toxicity and genotoxicity of four chromium compounds using the SOS Chromotest and ATP-TOX biomonitoring screening procedures. It was found that the compounds exhibit general toxicity at concentrations lower than those at which genetic damage occurs. Thus indicating that both toxicity and genotoxicity must be considered in the environmental assessment of chromium compounds"--Management perspective.
