摘　　要：2008年4月—2008年6月对淮南市的5个采样点PM10连续采样,分析了其中多环芳烃(PAHs)。PAHs质量浓度的最大值和最小值分别为112 ng/m3和15.2 ng/m3,PAHs春季质量浓度均值为40.2 ng/m3;PAHs组成以4环和5环为主;春季不同采样点PAHs质量浓度与环境温度呈负相关关系,运用PAHs比值综合判断,淮南市春季大气PM10中PAHs主要来源于燃煤和机动车尾气。The inhalable particulates samples were collected from April to June in 2008 at Huainan, and 16 kinds of PAHs were analyzed. The maximum concentration of PAHs was 112 ng/m^3 , and minimum concentration 15.2 ng/m^3 , average concentrations 40.2 ng/m^3 in three months of the spring. The concentrations were different in different sampling sites. Four and five-rings were a large majority of PAHs. The negative correlation was found between PAHs concentrations and temperature at different sampling sites in the spring. Source identification and apportionment of PAHs were processed by ration method to show that coal burning and vehicle emissions were the major sources of Anhui Huainan.
