Abstract
As industries began to proliferate around the Great Lakes and its tributaries, contamination also began to accumulate in its waters. PCBs, which do not biodegrade, were routinely discharged into the environment before scientific evidence revealed the consequences of their presence. Once in the water system, PCBs settle into the sediment and are introduced into the food web through microorganisms that live in the mud; they are biocumulative as they work their way up the food chain. By the time it reaches a fish you might put on your dinner plate, the concentration of PCBs has increased thousands of times.
