ORGANOCHLORINE CHEMICAL RESIDUES IN HERRING GULLS, RING-BILLED GULLS, AND COMMON TERNS OF WESTERN LAKE SUPERIOR

Residues of polychlorinated biphenyls (PCBs), DDE, DDT, and hexachlorobenzene (HCB) were analyzed for three age classes (e.g. pre-fledge muscle and blood, and post-fledge muscle) of the herring gull, ring-billed gull, and common tern for samples collected in the western end of Lake Superior in 1977....

Description
Summary:Residues of polychlorinated biphenyls (PCBs), DDE, DDT, and hexachlorobenzene (HCB) were analyzed for three age classes (e.g. pre-fledge muscle and blood, and post-fledge muscle) of the herring gull, ring-billed gull, and common tern for samples collected in the western end of Lake Superior in 1977. Concentrations of PCBs were highest and HCB concentrations were lowest of the chemicals analyzed in all four sample types and for all three species. Without exception, concentrations of all residues increased from the prefledge to the post-fledge stage despite this being a period of dilution. (Copyright (c) 1986 Springer-Verlag New York Inc.)
