采用二次离子质谱 (SIMS)对大气单颗粒物 (2 0 μm以下 )中的有机成分进行分析研究 ,从分析结果可以看出大气颗粒物中含有多环芳烃系列 (PAHs) ,包括致癌类多环芳烃
The analysis of organic components in atmospheric single particles (below 20 μm) by secondary ion mass spectrometry (SIMS) shows that PAHs (PAHs) are included in atmospheric particulates, including carcinogenic polycyclic aromatic hydrocarbons
