Concentration of atmospheric mercury: 2012 Northwestern Pacific Transect
Measuring atmospheric Hg in the marine boundary layer was monitored from September 12 to September 24 by the Hg GEM analyzer along the cruise track of R/V Araon from Nome(Alaska) to Incheon carrying out a series expeditions in the Northwestern Pacific Transect. Mercury (Hg) is a toxic pollutant. Its bioaccumulation causes serious health problem. In the atmosphere, mercury typically exists in gaseous elemental mercury (GEM), reactive gaseous species (RGM) and particulate bounded mercury (PBM). Since more than 95% of mercury exists in GEM, significant amount of Hg is transported long-range. In spite of the importance of mercury in the atmosphere, the role of ocean in the global budget of Hg has not been clearly studied yet and its measurement over the marine boundary layer will enhance the OH-related chemistry.
