An Evaluation of the Possible Detrimental Effects by the Introduction of Organic and Second-Order Organics on Commercial and Sport Fishing in Lake Superior

摘要

The improvement of sports fishing in the St. Louis River, the largest river system flowing into Lake Superior, is consistent with a decreased level of solubilized chlororganics in the spawning regions of the river owing to the diversion of the Potlatch Paper Mill effluent to the new Western Lake Superior Sanitary District treatment plant located at the mouth of the estuary. The study developed two approaches to the analysis of a complex matrix of chlororganics such as that associated with the St. Louis River's regional sewage treatment plant handling industrial paper mill wastes.
