摘　　要：为了解鞍山市秋季大气细颗粒(PM2.5)中污染元素的污染特征和来源,于2014年10月在鞍山市6个监测点位采集PM_(2.5)样品,运用富集因子和相关分析法对元素的污染特征和来源开展研究.结果表明,Fe、Ca、Zn、Mg、Na、Pb元素浓度含量之和占所有检测的12种元素浓度的98.13%,是主要的污染元素;鞍山市秋季大气细颗粒物中污染元素主要来源于钢铁冶炼、机动车尾气与燃煤的混合型污染源.In order to understand the sources and characteristic of the polluted elements in PM2. 5during autumn of Anshan,PM2.5samples were collected in October 2014 and then enrichment factor and correlation analysis were used to identify the main sources of these elements. The results showed that the total concentration of the 6 elements（ Fe,Ca,Zn,Mg,Na,Pb） accounted for 98. 13% of the concentration of 12 detected elements. The results also indicated that the main sources of the elements in PM2. 5were the traffic exhaust,coal burning,Iron and steel smelting.
