Characterization of Chemical Composition of Polycyclic Aromatic Hydrocarbons (PAHs) Emitted from Indoor Sources

  • 摘要: 运用环境舱模拟源排放的方法采集了烹调油烟与环境烟草烟雾的样本,对18种PAHs进行了定量分析.比较了不同食用油与不同品牌香烟产生PAHs组成特征的差异,初步建立了2类室内PAHs来源的化学成分谱.结果表明:烹调油烟中3环以下的PAHs为主体,Fluo,Pyr和Flu相对含量较为稳定;香烟烟雾以3~4环组分为主体,Flu,Phe,InP和BaA较为稳定,Cor含量较烹调油烟而言显著增加.2类源的ρ(BaA)/ρ(Chy),ρ(BeP)/ρ(BaP)与ρ(InP)/ρ(BghiP)稳定且存在显著差异,可以用来解析室内PAHs以及PAHs暴露的来源.运用等效毒理学因子估算了其危害程度,结果表明:每100 g食用油在烹调过程(60 min)中释放产生PAHs的毒理学效应仅为吸烟过程中每g烟草所产生PAHs毒理效应的一半.
