Methylmercury production and export in permafrost peatland catchments of the Taiga Plains

February 15 @ 12:00 pm - 1:00 pm


Lauren 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 may shift environmental conditions to facilitate microbial production of methylmercury (methylation). However, the degree to which mercury is methylated post-thaw and exported downstream remains uncertain in northwestern Canada and poses a potential hazard for uptake by aquatic food webs.
