Methylmercury production and export in permafrost peatland catchments of the Taiga Plains
OnlineLauren Thompson, University of Alberta Ongoing permafrost thaw in northern peatland catchments may increase the production and downstream delivery of neurotoxic methylmercury across the terrestrial-aquatic continuum. Peatlands in boreal-Arctic regions have large stocks of mercury in frozen soils, accumulated through atmospheric deposition of natural and human-emitted mercury over thousands of years. Permafrost thaw in peatlands […]
