　　报告摘要：Atmospheric mercury is operationally defined as gaseous elemental mercury (GEM), gaseous oxidized mercury or reactive gaseous mercury (GOM), and particulate-bound mercury (PBM). Monitored mercury speciation data (GEM, GOM and PBM) at multiple locations have only become available in recent several years. This talk includes two parts with the first part briefly summarizing recent studies making use of mercury speciation data and the second part discussing the mercury dry deposition project within the National Atmospheric Deposition Program (NADP) in North America. The first part covers measurement challenges and uncertainties, various data analysis and applications, and future research needs. The second part describes the approach used for estimating mercury dry deposition and major results generated from the first six-year data of the mercury speciation network.
