以河南省3类典型工业区域为例，分析研究其土壤中多环芳烃类化合物的种类组成及含量分布特征，结果表明：3类典型工业区域周边土壤中均检出14种 PAHs，其中萘、芘、艹屈、苯并[a]蒽具有较高的检出水平；大型化工企业周边土壤中 PAHs的检出率高于油田和工业园区；检出的14种 PAHs的总质量比均值，大型化工企业明显高于油田和工业园区；3类典型工业区域土壤中 PAHs测定值明显高于背景值，表明土壤已受到 PAHs 的影响；来源分析表明，PAHs 的污染主要源自石油和燃料的燃烧。
以河南省3類典型工業區域為例，分析研究其土壤中多環芳烴類化閤物的種類組成及含量分佈特徵，結果錶明：3類典型工業區域週邊土壤中均檢齣14種 PAHs，其中萘、芘、艸屈、苯併[a]蒽具有較高的檢齣水平；大型化工企業週邊土壤中 PAHs的檢齣率高于油田和工業園區；檢齣的14種 PAHs的總質量比均值，大型化工企業明顯高于油田和工業園區；3類典型工業區域土壤中 PAHs測定值明顯高于揹景值，錶明土壤已受到 PAHs 的影響；來源分析錶明，PAHs 的汙染主要源自石油和燃料的燃燒。

Taken three classic industrial estate in Henan province for example,the specific composition and content distribution of the PAHs in soil were studied.The results showed that:14 kinds of PAHs were detected in soil of three classic industrial estate.Naphthalene,Pyrene,Chrysene and Benzo [a]anthracene were detected at high levels in 14 kinds of PAHs.The average mass ratios and the detection rates of PAHs in soil of large chemical enterprises were obviously higher than that of oil fields and industrial estates.The contents of PAHs in soil of typical industrial estates were obviously higher than that of backgrounds,which shows that the soil is al-ready contaminated by PAHs.
