Congressional visit to discuss sources of mercury in the Great Lakes

By Upper Midwest Water Science Center February 2, 2016

WI WSC scientist Dave Krabbenhoft met with staff of the House Natural Resources Committee on Jan. 11, 2016, to discuss a new tool that can "fingerprint", or identify, Great Lakes mercury sources such as atmospheric, industrial, or watershed runoff. Determining where the mercury originates from helps inform management and mitigation planning.

Sources of mercury (Hg) in Great Lakes sediments were assessed with stable Hg isotope ratios using multicollector inductively coupled plasma mass spectrometry. An isotopic mixing model based on mass-dependent (MDF) and mass-independent fractionation (MIF) (δ202Hg and Δ199Hg) identified three primary Hg sources for sediments: atmospheric, industrial, and watershed-derived. Results...
