摘要
本文报告了重庆大气可吸入颗粒物(IP)中多环芳烃(PAH)的分析测定方法和结果.用GC-MS定性和定量分析了重庆IP中的PAH;研究了IP中PAH的种类和分布情况;确认重庆IP中存在甲基多环芳烃(MePAH)、约占33%;颗粒大小分布表明,约有98%PAH存在于小于3μm的颗粒中.
This paper reports determination method and results of Polycyclic aromatic Hydrodcarben (PAH) at Inhalable Particles (IP) in Chongqing Atomorsphere. The PAH in Chongqing IP is analysed qualitatively and quatitatively by GC-MS. Kind and distrubition of PAH in IP is studied. It is determined that Methyl polycyclics
aromatic Hydrocarbon (MePAH) is in IP and MePAH is 33% of all PAH. Size distribution shows that about 98% of PAH is present in < 3 μm particles.
