我国大气细颗粒物中金属污染特征及来源解析研究进展

A review of atmospheric fine particulate matter associated trace metal pollutants in China

以PM2.5中金属元素为研究对象,综述了2000—2012年我国在PM2.5中金属的污染水平、时空分布特征、污染来源解析方法及应用等领域的研究进展.目前我国普遍面临严重的PM2.5污染,作者提出应系统开展我国PM2.5中金属污染研究,特别要加强针对农村及背景地区的研究;开展PM2.5中金属的迁移转化机理研究;加快建立污染源排放清单;加强区域污染传输特征研究,以便更好地开展PM2.5的来源解析,为环境管理部门制定大气重金属污染控制目标提供参考.

This paper which focused on the metal elements pollution of PM2. 5has summed up the progress in the studies of pollution level,spatial variations and applications of pollution sources analysis in china between 2000 and 2012. Currently,we are facing severe pollution of atmospheric fine particles（ PM2. 5） in our country. The researches on temporal and spatial distribution characteristic and source apportionment,especially in rural and background areas,should be strengthened.
