Presented by Carl Brown and Don Essig, Idaho Department of Environmental Quality

There are a number of Idaho water bodies that have fish advisories for mercury. While contamination concerns for mercury focus primarily on fish and water, air deposition of mercury is the predominant source of the mercury found in water. A general discussion of mercury air sources, transport, and deposition will be presented. Specific studies concerning deposition of mercury in Idaho will be summarized. Next the fate of mercury once it has fallen on the landscape will be described, i.e. how it goes from the watershed to fish. Studies of mercury in fish tissue in Idaho water bodies will also be summarized.
