摘要(Abstract)：

研究使用大气干湿沉降自动采样仪于2013年8月至2014年10月采集了太原市30个大气干沉降样品，并对15种USEPA优控多环芳烃(PAHs)的污染特征和来源及生态风险进行了研究。结果表明太原市干沉降中∑15-PAHs的水平为(8.19～62.31)μg/g,均值为24.37μg/g,污染水平较高；PAHs主要组成成分为Phe、Fla、Pyr和chr,环数以3、4环为主。特征比值法和主成分分析结果显示太原市干沉降中PAHs的三大主要来源为燃煤、机动车和焦化产业。干沉降通量和∑15-PAHs的干沉降通量范围分别为(157.44～358.17)mg/(m~2·d)和(2 436.20～13 616.80)ng/(m~2·d),太原市全年颗粒物和∑15-PAHs沉降量为6.89×10~5 t和18.18 t.干沉降中PAHs的毒性当量浓度范围为(0.67～2.94)μg/g,均值为1.55μg/g.生态效应区间法评价结果显示82.76%的干沉降样品所含PAHs生态风险水平较高，应引起高度重视。
