Abstract
Sediment burial provides a pathway by which persistent organic pollutants (POPs) may be removed from the Great Lakes, acting as a sink. However, surficial sediments resuspended because of intense, large-scale storms during the late winter in southern Lake Michigan may be a source of POPs to the water column. Spatially coordinated air, water, and settling sediment samples were collected to examine the impacts of large-scale sediment resuspension in southern Lake Michigan. Field sampling was conducted during the late winter and spring of 1998, 1999, and 2000 when the lake was unstratified and Samples were collected during three years in which the intensity, spatial extent, and duration of sediment resuspension differed. This resulted in nearly 400 samples that were analyzed for polychlorinated biphenyl congeners (PCBs), polycyclic aromatic hydrocarbons (PAHs), and chlorinated pesticides such as DDT and its daughter compounds. Data resulting from field sampling and process modeling is being used to evaluate these event-related effects on (a) the concentration of POPs in air, water, and settling sediment; (b) the short-term fate using the unique chemical characteristics and patterns of POPs to trace the sources of resuspended sediment; and (c) the long-term fate and bioavailability by using changes in partitioning of POPs.
