摘　　要：采集济南市环境空气样品和污染源样品,分析其化学成分。采用化学质量平衡(Chemical Mass Balance,CMB)源解析技术,研究探讨济南市环境空气中PM2.5的来源。结果表明:对济南市有明显贡献的颗粒物源类是煤烟尘、机动车尾气尘、土壤尘、扬尘、建筑尘、钢铁尘、硫酸盐和硝酸盐等,并且城市区域尘大于外来尘的贡献,各源类PM2.5贡献值和分担率的季节变化较明显。The chemical constituents of air and pollution sources of Jinan were tested and analyzed. Source apportionment technology -CMB model is adopted and the sources of PM2.5 in Jinan were studied. It is showed that the coal dust, vehicle exhausted dust, soil dust,ground dust, construction dust, steel dust, sulfate and nitrate are the main particulate matter sources, and that dust in urban environment contributes more than imported dust and the PM2.5 contribution value and the ratio of sources obviously change with season.

关 键 词：PM2.5 CMB模型 贡献值 分担率
