EmilyLearning how to take pore water samples from a bog! In addition to our surface water samples, we're interested in elemental and methyl-mercury concentrations in the subsurface. <a href="https://pixelfed.social/discover/tags/mercury?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#mercury</a> <a href="https://pixelfed.social/discover/tags/methylmercury?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#methylmercury</a> <a href="https://pixelfed.social/discover/tags/umn?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#umn</a> <a href="https://pixelfed.social/discover/tags/research?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#research</a> <a href="https://pixelfed.social/discover/tags/bog?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#bog</a> <a href="https://pixelfed.social/discover/tags/peatland?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#peatland</a> <a href="https://pixelfed.social/discover/tags/waterquality?src=hash" class="u-url hashtag" rel="nofollow noopener noreferrer" target="_blank">#waterquality</a>

The research team was led by Jacqueline R. Gerson, as a Ph.D. student at Duke University.“What this study found was that the wildest forests left on earth are capturing mercury released by artisanal mining, and at superfund-site levels,” said Miles Silman, Andrew Sabin Presidential Chair of Conservation Biology and Director of Wake Forest’s Center for Energy, Environment and Sustainability. 'The wildlife and humans that live within these wild forests are poisoned as well, with effects that we are just beginning to understand.'"''This study reveals, for the first time, the mechanism of how mercury released into the air by gold mining contaminates <a href="https://kolektiva.social/tags/TropicalForests" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TropicalForests</a> and forest <a href="https://kolektiva.social/tags/soils" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#soils</a>,' Fernandez said. “This atmospheric mercury, which is either deposited on to leaves or absorbed by leaves, eventually falls to the ground and gets incorporated into forest soils.'"The region of <a href="https://kolektiva.social/tags/MadreDeDios" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MadreDeDios</a> is considered a global <a href="https://kolektiva.social/tags/biodiversity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#biodiversity</a> hotspot, but in recent decades has suffered an unprecedented <a href="https://kolektiva.social/tags/GoldRush" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldRush</a>. mining is doing irreversible damage to one of the world’s largest remaining pieces of <a href="https://kolektiva.social/tags/TropicalRainforest" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#TropicalRainforest</a> and threatening its survival. In the Madre de Dios region of Peru, east of the Andes Mountains, nearly 250,000 acres of rainforest, roughly the size of Dallas, Texas, have been razed and transformed into somewhere that looks like a desert pockmarked by tens of thousands of mercury contaminated mining ponds by illegal <a href="https://kolektiva.social/tags/GoldMining" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldMining</a>."Gold miners use toxic mercury to pull flakes of gold out of the river sediment. Then, they separate the gold from the mercury using open fire ovens. The heat melts the gold and turns the mercury to a toxic vapor."'People had a lot of ideas about where mercury might be going in these tropical landscapes, and they turned out to be wrong,' Silman said. 'The paper shows that mercury isn’t staying in the mining zone, but rather that trees are scrubbing mercury from the air and transferring it into forest <a href="https://kolektiva.social/tags/ecosystems" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ecosystems</a>, and into forest wildlife and peoples, where it moves up the food chain with unknown effects.'"The study also reveals how these contaminated soils serve as a repository for this deposited mercury, preventing. or at least slowing, its transfer into rivers and lakes where it is transformed into a more toxic form of mercury, <a href="https://kolektiva.social/tags/Methylmercury" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Methylmercury</a>, and contaminate aquatic food webs."<a href="https://news.wfu.edu/2022/01/28/amazon-forests-poisoned-by-mercury-from-gold-mining/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://news.wfu.edu/2022/01/28/amazon-forests-poisoned-by-mercury-from-gold-mining/</a><a href="https://kolektiva.social/tags/WaterIsLife" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WaterIsLife</a> <a href="https://kolektiva.social/tags/GoldMine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldMine</a> <a href="https://kolektiva.social/tags/GoldMining" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GoldMining</a> <a href="https://kolektiva.social/tags/Cyanide" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Cyanide</a>
