Enhanced methylmercury formation in thawing permafrost peatlands of northwestern Canada

Tracing links between DOM quantity and composition, TEAs, and microbial communities can provide valuable information on the trajectory of MeHg production in rapidly thawing northern peatlands. Here, we investigated MeHg production in thawing peatlands by analyzing the chemistry of soil and porewater, hgcAB gene abundance, and potential HgII methylation rates.
