Louis River estuary have much higher mercury than those in nearby lakes, salmon mercury even the same river upstream, or than Lake Superior just downstream. UMD researchers gather a sample of St. Louis River estuary sediment to be tested for mercury. Scientists from multiple universities and agencies gathered data for years to determine why so much mercury was showing up in walleyes in the estuary.

The study concluded that much of the mercury has been in the sediment for decades.

Mercury was ubiquitous in both household and industrial uses in the s and s, said Joel Hoffman, a research biologist and co-author of the study who is chief of the Ecosystems Services Branch of the EPA's Duluth laboratory. Those sources likely included paper mills, lumber mills, steel mills, shipbuilding sites, manufacturing facilities and other sources that once dominated the river and Twin Ports harbor shoreline. Much if it was probably dumped into the river. Salmon mercury with the unique nature of the estuary, where so-called seiche currents can push water upstream as well as the usual downstream movement, more old mercury became trapped in wetlands and bays throughout the estuary, not just near heavy industrial sites. The research helped rule out other potential sources of mercury, like higher local doses falling from the salmon mercury.

Louis River estuary sediment was on average 10 times higher than sediment from the Bad River, which scientists used for comparison in the study. Less than miles away and subject to the same airborne mercury deposition patterns for new mercury, but salmon mercury affected by historic onsite industrial or urban mercury sources, the Bad River served as the heights lifetime for the research.

Scientists also found mercury levels in the walleye from the St. Louis River estuary were on average twice as high as those in Bad River fish. Louis River had levels of mercury higher than federal guidelines for human consumption. A big St. Salmon mercury River walleye, considered unsafe for women and children to eat. A new study salmon mercury found that the primary reason St. Louis River estuary walleyes carry so much toxic mercury is because of decades-old legacy mercury in the sediment.

Efforts to clean up that sediment may help salmon mercury the mercury levels in fish. According to a study by the Minnesota Department of Health released inone of every 10 babies born in the Lake Superior region of Minnesota had unsafe levels of toxic mercury in his or her bloodstream, likely because their mothers ate too much contaminated fish while pregnant. No matter what the source of the original mercury, the water in the St. Louis River is especially good at converting it to the toxic form, called methylation, because it has so much dissolved oxygen.

Tea-colored waters and those with ample salmon mercury have been known for years to allow more mercury to be converted to the toxic form and build up in fish. Read more the new study confirmed that fish that spend more time in the river had more mercury while salmon mercury that migrated out of the estuary, spending more time in Lake Superior where far less legacy mercury exists, had much less mercury in their tissue.

Globally, mercury pollution has been declining in recent decades, thanks in large part to less mercury going up smokestacks at coal-burning power plants. Some states, like Minnesota, also have gone to great lengths to reduce mercury in the waste stream, including catching mercury leaving dental offices and banning mercury in batteries, switches and other household items. But all those efforts were not reducing the mercury levels in St. Louis River fish because so much old mercury was still available in the ecosystem, sitting in the sediment waiting to be moved up the food chain from invertebrates to small fish, to big fish and then people.

A new study has found that unusually high levels of mercury in St. Louis River estuary walleyes, twice as high as in a nearby river, are due to decades-old legacy pollution still in the sediment.]
