General population exposure to environmental concentrations of halogenated biphenyls.
Halogenated biphenyls, terphenyls, naphthalenes, dibenzodioxins and related products. Kimbrough RD, ed. New York: Elsevier/North-Holland Biomedical Press, 1980 Jan; :267-286
Available data on the exposure of the human population to halogenated aromatic hydrocarbons is reviewed. The world production of polychlorinated biphenyls (PCBs) is estimated to have exceeded 1 million tons since 1930. Population surveys of groups in developed countries without occupational exposure to PCBs indicate that PCB residues are detectable in tissues. Human milk surveys indicate that PCB concentrations range from 0 to 960 parts per billion. The problem of PCBs in Lake Michigan fish is discussed. Surveys show that most specimens from Lake Michigan contain detectable PCBs. One survey reports that the mean whole fish concentration in 30 lake trout was 22.91 parts per million. Contamination in Bloomington, Indiana due to sewage sludge and in the midwest due to contaminated silage is also discussed. The industrial application and residue survey of human population exposure to polychlorinated terphenyls (PCTs) are considered. Background concentrations of PCTs in the population studied tend to resemble those of PCBs. The pathways of human exposure to PCTs also appear to resemble those of PCBs. Polybrominated biphenyls have been introduced into cattle feed as the result of a labeling accident in Michigan. Results of the accident are examined. The author concludes that human surveys of PCBs and PCTs show that residues of these compounds occur commonly in human populations.
