    • A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow 

      Steffen, A; Douglas, T; Amyot, M; Ariya, P; Aspmo, K; Berg, Torunn; Bottenheim, J; Brooks, S; Cobbett, F; Dastoor, A; Dommergue, A; Ebinghaus, R; Ferrari, C; Gardfeldt, K; Goodsite, ME; Lean, D; Poulain, AJ; Scherz, C; Skov, H; Sommar, J; Temme, C (Journal article; Peer reviewed, 2008)
      It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to have a long residence time ...

    • Carbonaceous aerosols in Norwegian urban areas 

      Yttri, Karl Espen; Dye, C; Braathen, OA; Simpson, D; Steinnes, Eiliv (Journal article; Peer reviewed, 2009)
      Little is known regarding levels and source strength of carbonaceous aerosols in Scandinavia. In the present study, ambient aerosol (PM10 and PM2.5) concentrations of elemental carbon (EC), organic carbon (OC), ...

    • How relevant is the deposition of mercury onto snowpacks? - Part 1: A statistical study on the impact of environmental factors 

      Durnford, D.A.; Dastoor, Ashu P.; Steen, Anne Orderdalen; Ryzhkov, A; Figueras-Nieto, D; Hole, Lars R; Aspmo, Katrine; Hung, Hayley; Berg, Torunn (Journal article; Peer reviewed, 2012)
      A portion of the highly toxic methylmercury that bioaccumulates in aquatic life is created from mercury entering bodies of water with snowpack meltwater. To determine the importance of meltwater as a source of aquatic ...

    • Natural and anthropogenic atmospheric mercury in the European Arctic: a fractionation study 

      Steen, Anne Orderdalen; Berg, Torunn; Dastoor, Ashu P.; Durnford, Dorothy, A.; Engelsen, Ola; Hole, Lars Robert; Aspmo, Katrine (Journal article; Peer reviewed, 2011)
      This study reports the longest time series of GEM, RGM and particle-bound mercury (PHg) concentrations from a European Arctic site. From 27 April 2007 until 31 December 2008 composite GEM, RGM and PHg measurements were ...

    • Ten-year trends in atmospheric mercury concentrations, meteorological effects and climate variables at Zeppelin, Ny-Ålesund 

      Berg, Torunn; Cole, AS; Engelsen, Ola; Steffen, A; Pfaffhuber, Katrine Aspmo (Journal article; Peer reviewed, 2013)
      Results from ten years of gaseous elemental mercury (GEM) measurements at Zeppelin station, Ny-A° lesund, Svalbard, show no overall annual trend between 2000 and 2009. Seasonal trend analysis showed significantly ...

    • Ten-year trends of atmospheric mercury in the high Arctic compared to Canadian sub-Arctic and mid-latitude sites 

      Cole, AS; Steffen, A; Aspmo, Katrine; Berg, Torunn; Pilote, Martin; Poissant, Laurelier; Tordon, R; Hung, Hayley (Journal article; Peer reviewed, 2013)
      Global emissions of mercury continue to change at the same time as the Arctic is experiencing ongoing climatic changes. Continuous monitoring of atmospheric mercury provides important information about long-term trends in ...
