Mercury Methylation and Sulfate Cycling in NE Minnesota Streams

This page contains links to studies conducted by (or for) the DNR - Division of Lands and Minerals, Reclamation Section. These reports relate to methyl mercury and sulfate cycling in NE Minnesota streams and in the St. Louis River estuary. Please also see reports on DNR studies of mercury in taconite stack emissions.
