Toxicol. 6, No. 6: 532-34 (Nov.-Dec. 1971) f 0650^) Seventy-nine lactatlng women from New Guinea and Texas had their breast milk assayed for the presence of polychlorinated biphenyls, a widespread ind. pollutant of the ecosystem. Twenty-eight of these women had serum samples assayed for polychlorinated biphenyls also. No polychlorinated biphenyls were detected in any of the samples. Samples of blood serum and milk were extd. with hexane. The blood ext. was coned, and analyzed by GC. A MicroTek 220 GC wit tritium foil det. was used.
