根据重庆市主城区地形、气象特征并结合能源消费的结构特点，识别主城区主要PM2.5污染源。采用了SEMTECH—DS机动车尾气分析系统采集机动车尾气样品，在采集燃煤尘、道路尘、土壤尘、冶金尘和建筑尘的典型末端排放样品的基础上，进行再悬浮采样。分析了各种污染源样品中的碳组分、水溶性组分以及无机元素组分的含量，建立重庆市主城区PM2.5的污染源样品成份谱。研究显示各成份谱都有明显的标识元素，源成份谱较为真实的反应了主城区PM2.5的污染源特征。

Sources of PM2.5 had been identified and apportioned in the Chongqing urban areas based on the combined characteristics for the geographic terrains, meteorology and energy consumption structure. The automobile tail gas samples were collected and analyzed by the SEMTECH-DS mobile analyzer system. The coal dust, road dust, soil dust, metallurgy dust and the construction dust samples were processed further by resuspension sampling system when initial samples were collected from the dust catcher, in-organization source and open conditions. Carbon com position, water-solubility component and inorganic component were obtained from samples test results, PM2.5 source profile were established subsequently. The results indicate that, representative element appear to dominate each source profile besides, literatures confirms the source profile approximate real conditions for PM2.5 in the urban areas.
