Abstract:

The available data regarding the environmental fate, aquatic toxicity, and mammalian toxicity of hexachloroethane, which is used in military screening smokes, were reviewed. the USEPA guidelines were used to generate water quality criteria for the protection of aquatic life and its uses and of human health. Hexachloroethane is thermodynamically stable when released into the atmosphere, with the main sinks being the stratosphere and the oceans. Hexachloroethane does not persist in surface water and groundwater however, the residence time in groundwater 330 days is substantially longer than in surface water. Hexachloroethane is slightly more toxic to freshwater fishes than to freshwater invertebrates. In general, saltwater species appear to be more sensitive to hexachloroethane than freshwater species. Hexachloroethane is not mutagenic in bacteria or in yeast, but it is carcinogenic in B6C3F1 mice.
