【摘要】 分析了国内外的资料,并结合几年来对北京地区的研究成果,讨论了饱和烃、多环芳烃等有机污染物在源解析方面的应用。利用饱和烃进行源解析主要依靠正构烷烃的分布特征和主峰碳、CPI、OEP等参数,以及姥鲛烷和植烷的Pr/Ph、Pr/C17、Ph/C18比值;甾烷及萜烷等环状化合物,性质非常稳定,可以作为化石燃料燃烧的有机示踪物。通常情况下,不同来源的多环芳烃,Ant/Phe、Flua/Pyr、BaA/Chr等比值有一定的差别;因此这些比值也可以作为重要的诊断参数。更多还原

【Abstract】 Analysing datas of domestic and oversea, this paper discusses the use of alkanes and PAHs in the source analysis. The distribution characters of alkanes, Cmax, CPI, OEP of alkanes, and Pr/Ph, Pr/C17, Ph/C18 of isoprenoid were often used. Besides, Steranes and terpanes are very stable, and maybe used as traces of the combustion of fossil fuel. To PAHs from different origins, the ratios of Ant/Phe, Flua/Pyr, BaA/Chr and so on are different. So, these ratios may become important diagnostic parameters.更多还原
