This study investigated the influence of bedrock lithology on MeHg concentrations in wetlands. Twenty\u2010five different wetland field sites were sampled over four different bedrock lithologies; Kejimkujik monzogranite, black sulfidic slate, gray slate, and greywacke. Soil samples were analyzed for ethylmercury (EtHg), MeHg, total Hg, acid\u2010volatile sulfides (AVS), organic matter, and water content as well as the biological parameters, mercury methyltransferase (HgMT) activity, sulfate reduction rates, fatty acid methyl ester (FAME) composition, and acidity. Methylmercury concentrations in the wetlands were highly dependent (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.08) on lithology with no significant difference between bogs, fens, and swamps.

Fatty acid methyl ester composition was also lithologically dependent (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.001) with biomarkers for\n                    <jats:italic>Desulfobulbus<\/jats:italic>\n                    spp. discriminating between sites containing high and low MeHg concentrations. Levels of MeHg in wetlands were predicted mainly (41% of the sum of squares) by HgMT activity that differed (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.009) between wetlands, with activity in bogs almost three times that present in swamps.
