- 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、排放特征和特征比值进行了比较.
- Abstract：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.
- Key words：civil coal combustion coke plant petroleum asphalt polycyclic aromatic hydrocarbons (PAHs) source profiles
