Toxic Contaminants and Ecosystem Health A Great Lakes Focus

About this book

Papers from a symposium sponsored by the American Society of Limnology and Oceanography examine the scientific, economic and political factors which affect pollution of the Lakes. Three questions are addressed: What changes have occurred in the Great Lakes community? What role have toxic substances had in effecting such changes? How can researchers better investigate these effects?
