汞因大气迁移和健康风险而备受关注，大气汞沉降的来源分析对于汞污染控制工作十分关键，而现有研究更多关注大气汞沉降来源的生产者责任，缺少对消费者的责任识别与探讨。本项目将以中国大陆为研究区域，开展基于消费侧的大气汞沉降模拟与来源分析的研究，具体包括：基于消费侧，对中国大气汞沉降进行模拟，识别并分析各省沉降的来源地区及特点；在来源地区识别的基础之上，进一步识别并分析各省沉降的来源行业及特点；依据各省沉降的来源特点，设定初步削减方案并评价模拟效果，确立具有区域差异化及地区间合作特点的削减方向。本研究成果将为大气汞沉降及来源的研究提供新的研究角度，对现有分析方法进行有力补充，同时也为我国在消费侧的汞污染控制工作提供参考。

Mercury (Hg) has received much attention due to its atmospheric transport and health risks. Source apportionment of atmospheric Hg deposition is very critical for Hg controls. The responsibilities of producer on atmospheric Hg deposition have drawn much attention, but few studies have identified and discussed the responsibilities of consumer. With mainland China as the research area, this research will conduct simulation and source apportionment of atmospheric Hg deposition in China based on consumption side. The research contents are as follows. Based on consumption side, the distribution of atmospheric Hg deposition in China will be simulated, and the source area of deposition over each province will be identified. Furthermore, based on the results of the identification of source area, the source economic sectors of deposition over each province will also be identified. According to the features of source for each province, preliminary reduction plans will be made and their associated efficiency will be evaluated. Thus, the reduction orientation of interregional differences and cooperation will be established. The results of this research will provide a new perspective for the study of atmospheric Hg deposition, and a powerful complement for existing methods. Meanwhile, the results will also provide information for the consumption-side Hg controls in China.
