Recent studies of Arctic and Subarctic environments have detected rising levels of natural and anthropogenic mercury (Hg), putting northern residents at risk for Hg exposure. Within lake sediments, Hg can be methylated by certain species of Sulfate-Reducing Bacteria (SRB), a subset of Sulfur-Metabol...
