摘　　要：大气颗粒物的污染目前已经成为大气污染的首要问题。选择合肥市滨湖新区、董铺水库、琥珀山庄、高新区四个监测点PM2.5为研究对象,对重金属元素Cu、Ni、Zn、Pb、Mn、Cr、Co、Cd的含量、富集系数、可能来源展开研究。结果表明,合肥市初夏时节PM2.5中重金属元素质量浓度含量最高的是Zn。滨湖新区、琥珀山庄和高新区的Cu元素污染显著。根据SPSS软件分析推测滨湖新区Cu和Cd可能来自交通领域污染源,董铺水库的Fe和Mn可能来源于自然因素,琥珀山庄的Pb和Cd可能来自交通污染源,高新区的Ni和Cr可能来源于工厂的电镀操作。Pollution of particulate matter in air has become the most important issue of air pollution. Choose the Binhuxinqu, Dongpushuiku, Huposhanzhuang, Gaoxinqu four monitoring points in Hefei as the research object. The study mainly focused on the content of metal element, enrichment coefficient of heavy metals and possible sources of heavy metals of Cu, Ni, Zn, Pb, Mn, Cr, Co, Cd. The results shows that Zn has the highest concentration among heavy metals of PM 2.5 in early summer. The pollution of Cu element in Binhuxinqu, Huposhanzhuang and Gaoxinqu is severe. According to the results analyzed by SPSS, it can be predicted that the Cu and Cd in Binhuxinqu are likely derived from the transport sector, the Fe and Mn in Dongpushuiku are likely derived from nature, in Huposhanzhuang, the Pb and Cd are likely derived from the transport sector, Ni and Cr in Gaoxinqu may be derived from electroplating plant.
