【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2 179~11 933 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。更多还原

【Abstract】 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.更多还原
