摘　　要：以某退役炭黑厂地块为例,研究了土壤和地下水中多环芳烃和石油烃的空间分布特征,并通过特征组分比值法对其进行了溯源分析。结果表明:土壤中苯并(a)芘超标,最大超标倍数为4.8倍,超标点位在炭黑车间和仓库。地下水中萘和石油烃超标,最大超标倍数分别为5.6倍和29.5倍,超标范围为整个厂区。从特征组分比值法分析可知,多环芳烃污染主要来源于燃烧。该研究结果对退役炭黑厂的开发利用具有借鉴意义。This paper studies the spatial distribution characteristics of polycyclic aromatic hydrocarbons(PAHs)and petroleum hydrocarbons in soil and groundwater by taking the decommissioned plot of a carbon black plant as an example.The results showed that benzo(a)pyrene in soil exceeded the standard.The maximum exceeding multiple was 4.8 times,and the exceeding points were in the carbon black workshop and warehouse.The naphthalene and petroleum hydrocarbon in groundwater exceed the standard,with the maximum exceeding multiple of 5.6 times and 29.5 times respectively,and the pollution range covers the whole plant area.According to the analysis of characteristic component ratio method,the pollution mainly comes from combustion.This study is of significance for the development and reuse of retired carbon black plants.
