title: Nonoccupational exposure to polychlorinated biphenyls.
abstract: Polychlorinated biphenyls became worldwide environmental contaminants during five decades of industrial use. They cause cancer in some animals and are suspected of causing birth defects and elevated triglycerides in humans. The risk to humans from low-level exposure is unclear. No clinical symptoms have yet been identified in people who eat contaminated fish, a major source of low-level exposure.
