title: Levels of DDT and PCB compounds in North Atlantic fin-back whales.
abstract: DDT and polychlorinated biphenyl (PCB) compounds were found in blubber tissue samples of 12 North American fin-back whales collected in 1970 and 1971. Concentrations of DDT and metabolites ranged up to 2.557 ppm, while the highest PCB concentration was 0.185 ppm Gas chromatographic results were confirmed by chemical derivatization.
