Dissolved mercury from the southwestern region of Greenland accounts for an observed 10% increase in mercury in Arctic waterways. The mercury is believed to come from the bedrock on which the ice moves, so a \u201cnatural\u201d source that is increasing as glacier melt and runoff increases. Greenland\u2019s glacial catchments contain among the highest mercury levels recorded in natural waters; two orders of magnitude higher than from Arctic rivers. However, mercury from the Greenland Ice Sheet is not currently included in Arctic mercury budgets; despite its large and increasing annual runoff to the ocean, and the socio-economic concerns of high mercury levels in Arctic organisms. <\/p>\n<p><a href=\"https:\/\/www.nature.com\/articles\/s41561-021-00753-w\">https:\/\/www.nature.com\/articles\/s41561-021-00753-w <\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Nature Geoscience, May 24 The Greenland Ice Sheet releases relatively high concentrations of mercury in its runoff, sending large amounts of this heavy metal downstream into neighboring fjords.
