A STUDY OF PCB BIOACCUMULATION FROM WAUKEGAN HARBOR, LAKE MICHIGAN, SEDIMENTS BY THE OLIGOCHAETE, LUMBRICULUS VARIEGATUS

Abstract

The Lake Superior Research Institute (LSRI) of the University of Wisconsin-Superior contracted with the Chicago District of the U.S. Army Corps of Engineers to perform a study of the bioaccumulation of PCBs from Waukegan Harbor sediment by the oligochaete, Lumbriculus variegatus. In addition to determining PCB concentrations on a congener-specific basis in the sediment and exposed organisms, measures of total organic carbon (TDC) in the sediment and percent total lipids in the organisms were obtained.
