Available in PDF, EPUB and Kindle. Book excerpt: Concern about pesticide accumulation in the Upper Great Lakes prompted studies along Lake Superior's North Shore to provide current information on pesticide levels and contamination. Water samples were analyzed from the Grand Marais, the Duluth Pumping Stations, and the Duluth sewage treatment plant. Clams were exposed for bioassay purposes in 22 streams because they are concentrators of toxic substances, including chlorinated hydrocarbons, and reveal DDT and related compounds present in amounts below detection by ordinary analytical procedures. Under normal flow conditions, very little insecticide contamination was being contributed to Lake Superior from the drainage basin. Highest values occurred in the Lester and Lower St. Louis Rivers and in sewage effluent.
