PCBs and the Family Physician.
Pcbs are widespread environmental contaminants present in virtually every mammal on earth. Great controversy and debate has been evoked over the past two decades concerning their potential toxicity. They, along with other organochlorine compounds such as DDT, have been reasonably well studied in field and experimental situations.In general, PCBs are not very toxic, especially in concentrations to which most people are exposed, even those who work in the industrial setting or who eat contaminated fish. In terms of environmental hazards to health, PCBs should be considered as relatively low on the list. The public cannot depend on media information as a source of objective knowledge on controversial compounds like PCBs. The family physician should be able to provide to concerned individuals objective information on the definition, sources and relative toxicity of PCBs.
