摘　　要：对2008年05至11月淮南市5个采样点大气可吸入颗粒物（PM10）样品进行分析,总结了研究区内PM10及其中16种PAHs的浓度特征、季节变化规律和来源解析。研究区内16种PAHs浓度总和的范围在15.20-111.58ng.m^-3之间,平均值为40.40ng.m^-3,中位数为33.34ng.m^-3。PAHs总量的季节变化与采样时环境温度显示出较好的负相关性,即秋季〉春季〉夏季;运用多环芳烃比值综合判断,淮南市大气PM10中PAHs主要以燃煤和机动车尾气混合来源为主,石油源和木材燃烧来源的贡献较小。Inhalable particulates samples were collected at five different sampling sites in Huainan city from May to November,2008. The samples were analyzed for PM10 and 16 PAHs. Concentrations, seasonal changes and source identifications of PM10 and 16 PAHs were illustrated. Concentrations of 16PAHs are 15.20ng· m^- 3 · 111.58ng · m^- 3, average value 64.36ng· m^- 3 and medium 33.34ng· m^- 3 . Seasonal concentration of PAHs well displayed negative correlation with the surrounding temperatm＇e of sampling time, that is autumn 〉 spring 〉 summer. Several PAHs ratios judged complexly that PAHs in atmospheric PM10 in Huainan mainly came from the mixed source of coal combustion and vehicle emission. The contribution of petroleum and wood combustion sources was less.
