Toxic pollution in Lake Superior is low compared to the other Great Lakes; however, mercury, dioxin, and PCBs can harm lake wildlife because they don't easily break down, lasting a long time in the lake. In 1991, an agreement to reduce toxins was made between the United States and Canada, including the governments of Michigan, Minnesota, Wisconsin, and the province of Ontario. Read about current fish advisories (leaves EEK!) that will tell you about limiting the amount of fish you eat from this lake. | Toxic pollution in Lake Superior is low compared to the other Great Lakes; however, mercury, dioxin, and PCBs can harm lake wildlife because they don't easily break down, lasting a long time in the lake.
