Abstract |
Mass balancing of all direct and indirect multiple sources, pathways, and sinks of toxic contaminants can provide a knowledge base for adequate control and management of the Great Lakes Basin. The Green Bay/Fox River Mass Balance Study is a major coordination of environmental research activities among some eleven State and Federal agencies to measure major loads and the fate and movements of PCBs, dieldrin, cadmium, and lead in and out of the Green Bay/Fox River ecosystem. In the period between August 1988 and September 1989, measurements of bottom sediments, Bay-Lake exchange, atmospheric deposition, tributary loads, biota, etc., will be made; analysis will be carried out through June 1990, with the final report scheduled of September 1991. |
