采集了徐州市具有代表性的9个点位的春季环境空气样品，对不同功能区的监测点PM10及PM2.5污染水平及其来源进行了分析。结果表明，徐州市区代表不同功能的监测点污染特征明显，PM10与PM2.5污染主要来源于燃煤（包括电厂、其他工业）等固定源、机动车移动源，并受到工业废气、建筑施工扬尘等的影响。其水溶性离子、金属成分污染水平与其他城市相当，但由于受燃煤电厂的影响，Pb，Mn，As，Cr含量明显高于其它城市。

Typical ambient air samples were collected from 9 points of Xuzhou in spring and the pollution level and resources of PM10 & PM2.5 in different functional zones were analyzed. The result showed that, the pollution traits were obvious for different functional zones. The main sources of PM10 & PM2.5 pollution were stationary sources such as coal combustion industry (including power plant and other industry) and moving sources such as motor vehicles. They were also affected by industrial waste gas and construction dust. The pollution level of water-soluble ions and heavy metals were similar to other cities, but the content of Pb, Mn, As, Cr were obviously higher than other cities because of the effects of coal-fired power plants.
