ENVIRONMENTAL CONTAMINANTS IN FISH DIETS OF LAKE SUPERIOR CHIPPEWA

Abstract

Walleye, lake trout, siscowet trout, and whitefish were obtained in two collections from Apostle Islands National Lakeshore (AINL) as a representative sample of fish consumed by the Red Cliff Band of Lake Superior Chippewa people and subsequently fed to laboratory rats in a neurotoxicity bioassay. Carp were collected from Little Lake Butte des Martes, Green Bay, Wisconsin, to be used as a PCB positive control; and Pacific Salmon were analyzed for future use a a negative control species. All fish were prepared as fillets, ground into composite samples by species, analyzed for PCBs, mercury (Hg), and several other organochlorines.
