Includes bibliographical references. "Elevated levels of mercury in sediments of Thunder Bay North Harbour, Lake Superior, have led to several investigations by Environment Canada. The impact on invertebrate communities, sediment toxicity, and the bioavailability of this mercury and its potential for effects on fish and wildlife through biomagnification was assessed in 2002. The purpose of this study was to fill data gaps in two critical areas of the harbour that were determined from the 2002 study: (a) in the vicinity adjacent to the paper mill where toxicity and potential for biomagnification were observed, and (b) in the vicinity of the Current River mouth, where potential for biornagnification was observed"--Abstract.
