POLYCHLORINATED BIPHENYLS IN LAKE MICHIGAN TRIBUTARIES

Edwin A. Marti and David E. Armstrong, Water Chemistry Program, University of Wisconsin, 660 North Park Street, Madison, Wisconsin, 53706

ABSTRACT: PCB concentrations were measured in 14 major tributaries to Lake Michigan on samples collected in 1980-83. Mean total PCB concentrations ranged from 7 to 103 ng/L and were related to evidence of river or sediment contamination. Aroclor 1242/1248-like mixtures were dominant. Association of PCBs with suspended particulate matter averaged 53 to 83% and was influenced by suspended particulate matter concentration and PCB mixture composition.

KEYWORDS: Lake Michigan tributaries, polychlorinated biphenyls, toxic substances, pollution load.
