Trends of legacy and emerging-issue contaminants in Lake Simcoe fishes
published August 2010 http://jackson.eeb.utoronto.ca/files/2012/10/Journal-of-Great-Lakes-Research_7_148-159.pdf
Conclusions
In conclusion, concentrations of total-PCB and total-DDT have generally declined in Lake Simcoe sport fishes (lake trout and whitefish) between the 1970s and 2007......
Contaminant concentrations were, for the most part, below the “complete restriction” consumption guidelines for the general population. The only exception was for the largest (N60 cm) lake trout, where concentrations of PCBs either approached or exceeded this most restrictive guideline. The risk to the sensitive population was of more concern for the larger, predatory fishes (lake trout, largemouth bass, northern pike, smallmouth bass, and walleye for mercury, and whitefish for PCBs). PCNs and PBDEs were below the consumption guidelines for the measured species. Overall, contaminant related issues appear to be of less or similar concern than in the Great Lakes.
