Residues of Polychlorinated Biphenyls (PCB) and Organochlorine Insecticides in Liver Tissue from Terrestrial Danish Predatory Birds

Abstract
Several observations of the occurrence of PCB in marine organisms have been published since Jensen (1966) proved the presence of these compounds as pollutants in the environment. In the last years the occurrence in terrestrial animals, especially birds have been reported a.o. by Prestt & Moore (1970).
