Lethal impacts of selenium counterbalance the potential reduction in mercury bioaccumulation for freshwater organisms☆
Jacqueline R. Gerson, Rebecca A. Consbrock, Collin A. Eagles-Smith, Emily S. Bernhardt, David Walters
2021, Environmental Pollution (287)
Mercury (Hg), a potent neurotoxic element, can biomagnify through food webs once converted into methylmercury (MeHg). Some studies have found that selenium (Se) exposure may reduce MeHg bioaccumulation and toxicity, though this pattern is not universal. Se itself can also be toxic at elevated levels. We experimentally manipulated the relative...

Dong Feng, John Pohlman, Jorn Peckmann, Yuedong Sun, Yu Hu, Harry Roberts, Duofu Chen
2021, Chemical Geology (585)
Sulfate-driven anaerobic oxidation of methane (AOM) limits the release of methane from marine sediments and promotes the formation of carbonates close to the seafloor in seepage areas along continental margins. It has been established that hydrocarbon seeps are a source of methane, dissolved inorganic carbon, and dissolved organic carbon to marine environments. However, questions remain about the contribution of deep-sourced...
