摘　　要：利用模拟实验采集了民用燃煤污染源样品 ,在现场采集了焦化厂和石油沥青两类污染源样品 ,用GC MS联用技术测定了样品中 13种多环芳烃 .对分析结果进行归一化处理后确定以上 3类污染源多环芳烃源成分谱 .在此基础上 ,对民用燃煤、焦化厂和石油沥青污染源的排放水平、轮廓图特征。Samples were collected in lab for civil coal combustion and in field for coke plant and petroleum asphalt, 13 polycyclic aromatic hydrocarbons (PAHs) were determined by GC/MS. The PAHs fingerprints of the three sources were obtained by averaging the ratios of individual PAH concentration to the mass of the 13 PAHs measured. A comparison of the source profile, emissions and specific ratio between the three pollution sources was made.
