The findings from a binational scientific study indicate that efforts to control mercury pollution in the Great Lakes region have resulted in substantial and measurable improvements and that additional emissions controls will have multiple benefits for fish, wildlife, and people who consume fish from the Great Lakes region. However, mercury pollution remains a major concern in this region and the scope and intensity of the problem is greater than had been previously recognized. Biodiversity Research Institute and its collaborating research partners are actively addressing the need to continue mercury studies in areas most at risk and to convey this information to policy makers and regulators who are charged with the stewardship of our natural resources.
Great Lakes Mercury Connections distills key results from 35 new peer-reviewed papers accepted in special issues of two scientific journals:
The report represents the work of more than 170 scientists, researchers, and resource managers who used more than 300,000 mercury measurements to document the impact and trends of mercury pollution on the Great Lakes region.
Great Lakes Mercury Connections is a collaboration of Biodiversity Research Institute, the Great Lakes Commission based in Ann Arbor, Michigan, and the University of Wisconsin-La Crosse.
In 2008, the Great Lakes Commission, funded by the U.S. EPA, sponsored a scientific synthesis of information on mercury in air, water, fish, and wildlife through its Great Lakes Air Deposition (GLAD) program. BRI’s executive director, David C. Evers, Ph.D., was the principal investigator on the project. James G. Wiener, Ph.D., of the University of Wisconsin-La Crosse, and Charles T. Driscoll, Ph.D., of Syracuse University, were co-principal investigators on this project.
Mercury pollution is a local, regional, and global environmental problem that adversely affects human and wildlife health worldwide. As the world’s largest freshwater system, the Great Lakes are a unique and extraordinary natural resource providing drinking water, food, recreation, employment, and transportation to more than 35 million people.

The widespread loading of mercury into the Great Lakes environment is responsible for mercury-related fish consumption advisories in the eight U.S. states and the province of Ontario that border the lakes. Visit the U.S. EPA website and Ontario province’s Guide for more information.
For nearly 200 years, mercury has been released into the air and waterways of the Great Lakes region from human activities such as fossil fuel combustion, waste incineration, metal smelting, chlorine production, mining, and discharges of mercury in wastewater.
With funding from the U.S. EPA, the Great Lakes Commission sponsored a binational scientific synthesis effort through its Great Lakes Air Deposition program. The purpose of the synthesis project was to foster binational collaboration among mercury researchers and resource managers from government, academic, and nonprofit institutions to compile a wide variety of mercury data for the Great Lakes region, and to address key questions concerning mercury contamination, the bioaccumulation of methylmercury in food webs, and the resulting exposures and risks.
The synthesis effort began in November of 2008 and has involved more than 170 scientists and managers working to compile and evaluate more than 300,000 mercury measurements and to conduct new modeling and analyses.
