鞍山市总悬浮颗粒物中多环芳烃分布特征

通过对鞍山市典型区域（6个污染源、4个居住区、一个对照点）大气中总悬浮颗粒物（TSP）的监测，采用GC／MS法分析了总悬浮颗粒物中16种PAHs的含量，探讨了鞍山市总悬浮颗粒物浓度及16种多环芳烃的分布特征及来源。研究结果表明，鞍山市大气中总悬浮颗粒物采暖期普遍比非采暖期高1．1～2．5倍，总悬浮颗粒物中PAHs总量采暖期也远远高于非采暖期；鞍钢6个点位在非采暖期的PAHs总量均远远高于其他五个点位，表明了工业污染导致的环境空气质量下降是不容忽视的。

Distribution of PAH in TSP in Anshan

This study analyses 16 kinds of polycyclic aromatic hydrocarbons（PAHs） in total suspended particulates（TSPs） across the typical areas of Anshan（6 pollution sources ,4 residential areas and 1 control point）with GC/MS method. The distribu- tions and sources of 16 PAHs in TSP were investigated. Results show that the atmospheric TSP was higher by 1.1 to 2. 5 times in heating season than in non - heating season. The total concentration of PAHs was also much higher in heating period than in non - heating period. The total concentration of PAHs in six sites in Anshan Iron and Steel Group Corporation was much high than the other five sites even during the non - heating period, mirroring the significant impacts of industrial pollution on atmospheric envi- ronment.
