Abstract |
This report reviews and evaluates previously reported PCB levels in a variety of fish sampled from various locations in the Great Lakes. Higher concentrations in fish appear to be related to near-shore sampling where higher exposure to bottom sediments occurs to the flora and fauna comprising the food chains for the specific fish collected. Highest concentrations of PCBs were found in lake trout and fat trout taken from Lake Superior and in fish collected from the lower end of Lake Michigan. There is a need to identify past and/or present sources contributing PCB contaminants to the off-shore areas as well as to identify major sources of runoff contributing PCBs to the waters of the Great Lakes system. Additional information as to food-chain constituents is needed to more readily assess prey-predator relationships in the various regions of the system. |
