摘要：

采用1个样/km2的密度,1个分析组合样/25 km2的方法,对太原市区土壤中多环芳烃进行了调查。结果表明,太原市区土壤中多环芳烃的平均含量为865 μg/g;空间分布上北高南低,高值点主要位于工业区及交通要道地段;组成上以四环及四环以上的多环芳烃为主。通过与国内外城市土壤的对比可知,太原市土壤PAHs污染已相当严重，其来源主要是煤炭的燃烧。太原市工业布局、能耗类型和地理位置是造成土壤PAHs污染的主要原因。

Abstract:

Polycyclic aromatic hydrocarbons (PAHs) were quantified in 15 topsoils from Taiyuan CityConcentrations of ∑PAHs in topsoils ranged from 098 to 2623 μg/g with an average of 865 μg/g, and the spatial distribution of ∑PAHs declined from north to southThe abundance of the heavier PAHs was more than that of the low molecular weight PAHsBy contrasting Taiyuan with other cities, the pollution of PAHs in Taiyuan City was extremely serious and the primary source of soil PAHs was the coal combustionThe industry distribution, the energy structure and the location of Taiyuan City were the reasons of heavily pollution of PAHs
