PESTAB. To provide more data relating to the widespread occurrence of chlorinated hydrocarbons and toxic metals which accumulate in the tissues of marine birds, samples were collected from five Meditteranean seagulls and analyzed to determine the levels of chlorinated insecticides, polychlorinated biphenyls, PCT's, PCN's and the heavy metals, mercury, lead and cadmium. Each analyzed sample showed residues of the DDT and PCB groups; p,p'-DDE was found in all samples at higher levels than DDT. Lindane, heptachlor epoxide, and dieldrin were found in many tissues, but no heptachlor, aldrin, or endrin was found. Four birds had PCT residues; these same birds also had high PCB residues. PCN's were present in two liver samples. Heavy metals were found in all samples; lead had the highest concentration, followed by mercury and cadmium.
