Abstract
PCBs and DDT compounds are introduced and reintroduced into the waters of the Great Lakes as a result of atmospheric depositio and sediment resuspension. Atmospheric deposition of PCBs has previously been quantified by Steve Eisenreich and colleagues and appears to be the largest source. In fact, the atmosphere is probably responsible for buffering the lakes and preventing a more rapid cleansing of these compounds from the water. However, recent data indicates that resuspension of these compounds from open waters and from river deposits are also a major sources. We have recently quantified the inputs of PCBs and DDT from sediment resuspension as a result of large scale storms in Lake Michigan. Analysis of contaminant fluxes on settling particles show that approximately 370 kg of PCBs and 110 kg of DDT compounds are resuspended in southern Lake Michigan during a single basin-wide event. In this paper, the magnitude of these sources of PCBs and DDT is compared using a summary of field data and chemical distributions.
