摘要

An epidemiologic investigation of possible exposure to polychlorinated biphenyls (PCBs) was conducted following the discovery of widespread soil PCB contamination in Paoli, Pennsylvania. Concentration of PCBs in yard and street soil ranged from less than 1 ppm to more than 6,400 ppm. From several neighborhoods adjacent to the source of contamination, 66 persons were selected to represent the entire population of the neighborhoods (396 persons). The geometric mean and distribution of serum PCB concentrations in this group did not differ from the means and distribution of a large sample of persons selected from across the United States having no known environmental exposure. Thus, the population near the site in Paoli did not show exposure different from other U.S. populations having no known unusual source of exposure.
