In response to concern over elevated levels of methylmercury in fish tissue from catches in the state’s fresh water rivers and streams, a monitoring and assessment program has been developed to understand the sources, transport, transformation, deposition, biogeochemistry and assimilation of mercury.

The poster will describe the components of the overall program: caracterization of the major atmospheric emissions sources; studies of atmospheric processes – modeling and measurement; on-going ambient air and deposition studies; research on the biogeochemistry of mercury in a landscape setting; fish tissue monitoring, and socioeconomic implications of consumption advisories.

The study results will be briefly summarized with links to reports and principal investigators
