摘要: Abstract China is the largest atmospheric mercury (Hg) emitter in world. Its Hg emissions and environmental impacts need to be evaluated. In this study, China's emission inventory updated 2007 applied GEOS-Chem model simulate concentrations depositions China. Results indicate that simulations agree well with observed background concentrations. The anthropogenic sources contributed 35–50% of THg concentration 50–70% total deposition polluted regions. Sensitivity analysis was performed assess from power plants, non-ferrous metal smelters cement plants. It found plants are most important North China, Yangtze River Delta (YRD) Pearl (PRD) while contribution significant Southwest YRD, PRD Central
