Abstract:

通过采集典型矿区城市——黄石市新老城区大气颗粒物PM10和PM2.5的样品,并采用热解吸气质联用法对黄石市夏季大气颗粒物中多环芳烃(PAHs)的污染特征和来源进行了研究。结果表明黄石市老城区大气颗粒物中PAHs的浓度均明显高于新城区;在新、老城区大气PM10和PM2.5中PAHs的浓度变化范围分别为6.037~10.691ng/m3、12.132~18.440ng/m3和5.685~10.145ng/m3、9.314~15.998ng/m3;新、老城区大气颗粒物中低分子量PAHs含量较低,3环化合物呈相对优势分布,表明以石油源输入为主的来源特征,对比4环及其以上高分子量PAHs含量发现,老城区有明显的化石燃料不完全燃烧来源特征。
