Levels of PCBs, methyl mercury and dioxins in many Great Lakes fish Getting Worse

TOxins in many Great Lakes fish, such as salmon, rainbow trout, walleye, pike and lake trout are too high for human consumption, according to a new report called Up to the Gills: Pollution in Great Lakes Fish, by Environmental Defence, a Canadian conservation group. Despite some falls in contamination levels in certain parts of the Great Lakes, the report states that serious problems still exist and seems to be getting worse.
