摘要
在北京市区选择了有代表性的７个繁华路口，分冬（采暖期）、夏（非采暖期）两季，分别采集大气飘尘，用索氏提取法进行样品处理后，选用高效液相色谱──荧光检测方法对样品中的７种多环芳烃（ＰＡＨｓ）进行了分析测试。初步探索了交通要道口大气中ＰＡＨｓ的分布特征，并对ＰＡＨｓ间的相关性进行了研究。发现在北京交通类型的点污染源中，无论是采暖期还是非采暖期。ＰＡＨｓ与苯并［ａ］芘（ＢａＰ）均有密切的相关性。本研究弥补了北京市交通污染监测中缺少ＰＡＨｓ测试数据的不足。
In order to inspect the distribution characteristics and the concentration of polycyclic aromatic hydrocarbons (PAHs) along the traffic lines, a systematic analysis and monitoring measures of PAHs were adopted. The systematic sampling of atmospheric particle was taken at seven busiest traffic crosses in winter (season for beating supply) and summer (season without heating supply). By abstract and concentra tion, the samples were analyzed with HPLC-fluorescence detecter. Regardless the season with or without the heating supply, the concentration of PAHs shows close correlation with that of Benzo[a] pyrene.
