Organochlorine Concentrations in Burbot (Lota lota) Livers from Fairbanks, Alaska, and Kanuti, Tetlin, and Yukon Flats National Wildlife Refuges, Alaska, 1998 EXECUTIVE SUMMARY This study was conducted by U.S. Fish and Wildlife Service biologists during 1998 and 1999. Burbot liver was the tissue of choice for this study because chlorinated hydrocarbons, or organochlorine compounds, are lipophilic and burbot use the liver as their main somatic fat reserve (Love 1980). In addition, burbot consume high on the aquatic food chain and, therefore, are subject to the effects of biomagnification. The objectives of this study were to: determine the concentrations of organochlorine compounds in burbot livers at four sample sites in Interior Alaska; determine the significance of these data by comparing organochlorine concentrations in burbot livers with regional data for organochlorines...
