| 摘 要： | 采集南宁市郊4个传统蔬菜种植区内的耕作层土壤样品,利用超声波萃取结合高效液相色谱法对土壤样品中16种优先控制的多环芳烃进行检测和分析。结果表明:南宁市菜地土壤中总多环芳烃的含量范围为2632.00~5002.43μg·kg-1,平均为3351.30±1110.72μg·kg-1,处于严重污染水平;从多环芳烃的组成特征看,南宁市菜地土壤中低环(2~4环)多环芳烃含量占总含量的85.72%,其中3环的多环芳烃占比最大,达到54.62%;南宁市菜地土壤中的多环芳烃主要来源于机动车尾气的排放以及生物质和煤炭的燃烧。

| Abstract: | The contents and sources of 16 kinds of polycyclic aromatic hydrocarbons（PAHs），which are on
the list of priority control PAHs stated by USEPA，in soils from 4 traditional vegetable production bases of Nanning
City were analyzed by HPLC. The result showed that the content ranges of PAHs in soils of vegetable production
bases of Nanning City were 2 632.00～5 002.43 μg·kg-1 dry weight and the average value is 3 351.30±1 110.72
μg·kg-1. The PAHs pollution in soils was in severe polluted level. Most of PAHs in soil contained 2～4 aromatic
rings，and the content took 85.72% of the total PAHs content，among which PAHs of 3 aromatic rings occupied
the largest proportion 54.62%. The PAHs in vegetable production soil of Nanning City were mainly due to the
burning of biomass and fossil fuel and emission of motor vehicle exhaust. |
