摘要
通过收集江苏省徐州市区25个路面尘的样品,用GC-MS方法分析多环芳烃含量。结果表明,16种优先控制的多环芳烃在各采样点的总含量为2179~11933 ng/g,其中萘和菲的含量较高。比值法分析结果表明,燃烧和交通是徐州市二环路上多环芳烃的主要来源。
Road dust samples from 25 sites in Xuzhou city were collected and 16 EPA priority polycyclic aromatic hydrocarbons were analyzed via gas chromatograph/ mass spectrometry (GC-MS). The results showed that total PAHs concentrations (i.e. 16 EPA PAHs) ranged from 2 179 ng/g to 11 933 ng/g. Naphthalene and phenanthrene with relatively high concentrations were detected. The values of PAHs isomer showed that vehicular emission might contribute to the PAHs of road dust in Xuzhou city.
