A total of 10 surface soil samples representing the entire area of Linfen City were collected and analyzed for the presence of 16 polycyclic aromatic hydrocarbons. The total polycyclic aromatic hydrocarbon concentration ranged from 1.1 to 63.7 microg g(-1). Analysis of the sources of contamination revealed that polycyclic aromatic hydrocarbons in the soil were derived from combustion sources. Specifically, the primary source of polycyclic aromatic hydrocarbons was coal combustion, but the samples were also effected to varying degrees by traffic emissions. Furthermore, increased levels of contamination were observed in northeast Linfen due to the distribution of industrial plants.
共采集了代表临汾市整个区域的10个表层土壤样本，分析其中16种多环芳烃的存在情况。多环芳烃的总浓度范围为1.1至63.7微克/克。污染源分析表明，土壤中的多环芳烃来源于燃烧源。具体而言，多环芳烃的主要来源是煤炭燃烧，但样本也不同程度地受到交通排放的影响。此外，由于工业厂房的分布，临汾市东北部的污染水平有所增加。
