Mercury in the Water and Phytoplankton of Western Lake Erie

Objectives:  To determine the season concentration of mercury (Hg) in water and plankton in western Lake Erie, to assess the flux of Hg into the lake and to determine Hg bioaccumulation up the food chain.  Rationale:  The data from the samples collected will give a more comprehensive understanding of the distribution, dynamics and bioacculation of Hg through-out Lake Erie and the entire Great Lakes system. Managers and policy makers can then use this information to help estimate anthropogenic impact, ensure water quality and public health, and economic interests within the Lake Erie basin.   Methodology:  Will use ultra clean sampling and analytical techniques according to Gill and Fitzgerald (1985) and Bloom and Fitzgerald (1985) which are similar to EPA methods 163  and 1631 for Hg and methyl-Hg determination.
