Chromium Environmental Risk Assessment

A review of chromium environmental criteria, supporting scientific studies and recent research activities was conducted to determine the implications of evolving observations on cancer risk to DoD environmental clean-up programs. Public concern over the occupational cancer risk of hexavalent chromium is influencing a new assessment of the risk data. Toxicology literature on the human health hazards, cancer and non-cancer, was reviewed. On-going epidemiology efforts were unavailable for a thorough assessment. Data gaps in the literature were noted as support for research recommendations- Alternatives to chromium speciation at environmental clean-up sites were recommended as an interim measure. An extensive bibliography is provided.
