Abstract
Over time, thousands of kilograms of contaminants have accumulated in the sediments of the Great Lakes. This study examines the release of PCBs and DDT compounds from sediments as a result of large scale storms and sediment resuspension in the southern basin of Lake Michigan. This study was part of a large field effort called Episodic Events - Great Lakes Experiment (EEGLE) conducted in 1998 - 2000. The work described here concerns event-coordinated sampling of suspended and settling sediments conducted in 1998 - 1999 compared with surficial bottom sediments collected for the Lake Michigan Mass Balance Study in 1994 - 1995. All samples were analyzed for PCB and DDT compounds. Chemical profiles or signatures were examined by reviewing p,p-DDT/ p,p-DDE ratios, PCB chlorine number, and PCB congener distribution profiles in the samples. For the complex PCB congener signals, principal component analysis was used link regions of bottom sediment (sources) to settling sediments resuspended after storms, and to sediment suspended in the water.
