    • Effect of Climate Change on Air Quality 

      Jacob, Daniel J.; Winner, Darrel A. (Elsevier, 2009)
      Air quality is strongly dependent on weather and is therefore sensitive to climate change. Recent studies have provided estimates of this climate effect through correlations of air quality with meteorological variables, ...

    • Factors Driving Mercury Variability in the Arctic Atmosphere and Ocean over the Past 30 Years 

      Fisher, Jenny A.; Jacob, Daniel James; Soerensen, Anne Laerke; Amos, Helen Marie; Corbitt, Elizabeth Sturges; Streets, David G.; Wang, Qiaoqiao; Yantosca, Robert M.; Sunderland, Elynor M (Wiley-Blackwell, 2013)
      [1] Long-term observations at Arctic sites (Alert and Zeppelin) show large interannual variability (IAV) in atmospheric mercury (Hg), implying a strong sensitivity of Hg to environmental factors and potentially to climate ...

    • Langmuir Films of Polycyclic Molecules on Mercury 

      Tamam, L.; Kraack, H.; Slotskin, E.; Ocko, B. M.; Pershan, Peter S.; Deutsch, M. (Elsevier, 2007)
      Langmuir films (LFs) of biphenyl and anthracene derivatives on the surface of liquid mercury were studied by surface-specific X-ray and surface tension measurements. Phases of lying-down, side-lying and standing-up molecules ...

    • Legacy Impacts of All-Time Anthropogenic Emissions on the Global Mercury Cycle 

      Amos, Helen Marie; Jacob, Daniel James; Streets, David G.; Sunderland, Elsie M. (Wiley-Blackwell, 2013)
      Elevated mercury (Hg) in marine and terrestrial ecosystems is a global health concern because of the formation of toxic methylmercury. Humans have emitted Hg to the atmosphere for millennia, and this Hg has deposited and ...

    • Multi-Decadal Decline of Mercury in the North Atlantic Atmosphere Explained by Changing Subsurface Seawater Concentrations 

      Soerensen, Anne Laerke; Jacob, Daniel J.; Streets, David G.; Witt, Melanie L. I.; Ebinghaus, Ralf; Mason, Robert P.; Andersson, Maria; Sunderland, Elsie M. (American Geophysical Union, 2012)
      [1] We analyze 1977–2010 trends in atmospheric mercury (Hg) from 21 ship cruises over the North Atlantic (NA) and 15 over the South Atlantic (SA). We find a steep 1990–2009 decline of −0.046 ± 0.010 ng m−3 a−1 (−2.5% a−1) ...

    • 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 ...

    • Seasonal and Spatial Patterns of Mercury Wet Deposition in the United States: Constraints on the Contribution from North American Anthropogenic Sources 

      Selin, Noelle E.; Jacob, Daniel J. (Elsevier, 2008)
      Observed wet deposition fluxes of mercury in the United States show a maximum in the Southeast, and a consistent seasonal variation (maximum in summer, minimum in winter) that increases in amplitude from north to south. ...
