    • Global Biogeochemical Implications of Mercury Discharges from Rivers and Sediment Burial 

      Amos, Helen Marie; Jacob, Daniel James; Kocman, David; Horowitz, Hannah Marie; Zhang, Yanxu; Dutkiewicz, Stephanie; Horvat, Milena; Corbitt, Elizabeth Sturges; Krabbenhoft, David P.; Sunderland, Elynor M (American Chemical Society (ACS), 2014)
      Rivers are an important source of mercury (Hg) to marine ecosystems. Based on an analysis of compiled observations, we estimate global present-day Hg discharges from rivers to ocean margins are 27 plus or minus 13 Mmol a ...

    • Historical Mercury Releases from Commercial Products: Global Environmental Implications 

      Horowitz, Hannah Marie; Jacob, Daniel James; Amos, Helen Marie; Streets, David G.; Sunderland, Elynor M (American Chemical Society (ACS), 2014)
      The intentional use of mercury (Hg) in products and processes (“commercial Hg”) has contributed a large and previously unquantified anthropogenic source of Hg to the global environment over the industrial era, with major ...

    • Observed decrease in atmospheric mercury explained by global decline in anthropogenic emissions 

      Zhang, Yanxu; Jacob, Daniel James; Horowitz, Hannah Marie; Chen, Long; Amos, Helen Marie; Krabbenhoft, David P.; Slemr, Franz; St. Louis, Vincent L.; Sunderland, Elynor M (Proceedings of the National Academy of Sciences, 2016)
      Anthropogenic mercury poses risks to humans and ecosystems when converted to methylmercury. A longstanding conundrum has been the apparent disconnect between increasing global emissions trends and measured declines in ...
