化工厂周边土壤和大气沉降中多环芳烃组成分布特征及源解析

摘要
文章在研究16种不同类型的优控多环芳烃((PAHs)的主要含量以及其分布特征之时,以石化工业区附近20个表层土壤中的样品为基础,通过分析它被污染的程度以及污染物的来源,我们可知,不同采样点土样里面的16种PAHs质量浓度处于268.16-3304.60ug/kg范围之内,除去芴、苊,剩下的14种都被检出含有PAHs,由此可推断出此化工厂附近土壤几乎都被PAHs所干扰,并且污染较为严重,为中重度污染。
In this paper,the main contents and distribution characteristics of 16 different types of excellent polycyclic aromatic hydrocarbons PAHs were studied. Based on 20 surface soil samples near the petrochemical industrial zone,by analyzing the degree of pollution and the source of pollutants,we can see that 16 kinds of PAHs in soil samples from different sampling sites are is within the range of 268.16 to 3304.60 ug/kg, except fluorene and acenaphthene,the remaining 14 species were detected to contain PAHs. It can be inferred that the soil near the chemical plant was almost disturbed by PAHs,and the pollution was serious,which was moderately and severely polluted.
