Canada is worried about possible lead poisoning of the lakes

Canadian Foreign Affairs Minister Peter MacKay said Monday that Canada is worried about possible lead poisoning of the lakes, noting that the use of lead shot and sinkers in fishing gear is already banned.
Canada "has made its views known to the United States, and clearly, we will follow these consultations in the United States to make sure those views are further known, on the environmental side, the security side, to see that we get a proper resolution," MacKay told Canadian Press.
According to U.S. government data, the Coast Guard would become one of the largest sources of the toxic metal lead entering the Great Lakes if it goes through with the plan.
Coast Guard personnel would fire up to 430,000 bullets each year in the training zones, which are to be scattered across all five Great Lakes, according to The Muskegon Chronicle.
