Mercury in the ecosystem of Admiralty Bay, King George Island, Antarctica: Occurrence and trophic distribution
International audience Mercury (Hg) can reach the environment through natural and human-related sources, threatening ecosystems all over the planet due to its well-known deleterious effects. Therefore, Antarctic trophic webs, despite being relatively isolated, are not exempt of its influence. To eva...

International audience Mercury (Hg) can reach the environment through natural and human-related sources, threatening ecosystems all over the planet due to its well-known deleterious effects. Therefore, Antarctic trophic webs, despite being relatively isolated, are not exempt of its influence. To evaluate Hg concentrations in an Antarctic ecosystem, different tissues from 2 species of invertebrates, 2 of fish, 8 of birds, 4 of pinnipeds and at least 5 of vegetation were investigated (n=176). For animals, values ranged from 0.018 to 48.7 μg g−1 dw (whole Antarctic krill and Antarctic Fur Seal liver).
