| 摘 要： | 采用玻璃纤维滤膜(GF)和聚氨基甲酸乙酯泡膜(PUF)同时采集南京大气中颗粒态和气态上的多环芳烃(PAHs),用气质联用仪分析了16种优先控制的PAHs,研究了PAHs在南京大气中的相分布,研究结果表明,颗粒态和气态样品中16种PAHs的平均浓度值分别为20.49ng/m3和182.45ng/m3,2～3环的PAHs主要分布在气态中,而>4环的PAHs主要分布在颗粒态中。

| Abstract: | Polycyclic aromatic hydrocarbons(PAHs)in the atmosphere of Nanjing were collected simultaneously through GF film and PUF.Sixteen precedence-controlled PAHs of EPA were determined using gas chromatography with mass spectrometry detection(GC/MS).The phase-distribution of PAHs in the atmosphere of Nanjing was investigated,and results showed that the average total particulate and gas concentrations were 20.49ng/m3 and 182.45ng/m3 respectively.PAHs with two or three aromatic rings were mainly presented in the gas phase while PAHs with more than four rings were found mainly in particle phase. |
