Most low molecular weight chlorinated hydrocarbons such as chloroform, dichloromethane, dichloroethene, and trichloroethane are useful solvents. These solvents tend to be relatively non-polar ; they are therefore immiscible with water and effective in cleaning applications such as degreasing .

    We assessed chlorinated hydrocarbon contamination of mink and river otters on the Columbia and Fraser River systems of northwestern North America, in relation to morphological measures of condi-tion. We obtained carcasses of mink and river otters from commercial trappers during the winters and SUMMARY AND RECOMMENDATIONS: The oceans are an ultimate accumulation site for the persistent chlorinated hydrocarbons. As much as 25 percent of the DDT compounds produced to date may have been transferred to the sea. The amount of DDT compounds in the marine biota is estimated to be less than percent of total production, yet this amount has produced a demonstrable impact .

Between August and Septemberfish, crabs, and shellfish were collected from the lower Fraser River, its estuary, and selected areas of Georgia Strait in British Columbia.

Samples were analyzed for aldrin, dieldrin, alpha- and gamma-chlordane, p,p'-DDT, p,p'-DDE, p,p'-DDD, heptachlor, heptachlor epoxide, lindane, and polychlorinated biphenyls (PCB's).Cited by: 6. aI., ), fishes from areas ofunusual PCB pollution, such as the Duwamish River in Seattle, Wash.,~ juvenile es­ tuarine fishes (Butler and Schutzmann, ), and fish livers.5 Most previously published data deal­ ing with chlorinated hydrocarbons in marine life of the northeastern Pacific have come from southern California.

Hydrocarbons (chlorinated). -The book Silent Spring by Rachel Carson alerted the public to the dangers of chlorinated hydrocarbon pesticides.

The global spread of DDT and its unsuspected and dramatic impacts on nontarget organisms in distant areas. Water quality studies conducted in the recent past in the Lower Fraser River Basin indicated that locally some high pollution levels exist.

With further urbanization and industrialization of the Vancouver region an increase in waste loadings and a degradation of water quality can be expected if no strict pollution control is applied. Of particular concern are biologically undegradable.
