  • 摘要: 为了解农药企业搬迁遗留场地土壤中多环芳烃(PAHs)的分布特征,在某农药企业搬迁遗留场地的不同功能区设置采样点,分层采集土壤样品并分析其污染物的垂向分布特征.结果表明,在表层、亚表层土壤样品中PAHs含量较高,随着深度的增加土壤中PAHs含量逐渐下降,但下降幅度呈现出一定的波动性.通过研究污染物的组成以及土壤理化性质与污染物含量间的相关性分析发现,厂区土壤中PAHs含量与土壤有机质相关性显著,说明该场地土壤中的有机质是影响PAHs分布的重要因素之一.污染标志物参数分析表明,厂区PAHs主要来源于石油源.
    Abstract: In this study, the concentrations of PAHs from soil samples collected from different functional areas of a factory that previously manufactured pesticides in Changzhou were analyzed. Then the origination and distribution characteristics of PAHs in the brownfield were investigated. The results showed that the concentrations of PAHs in surface and subsurface soil samples were higher than that in deeper soil. PAHs content decreased gradually as soil depth increased. The downtrend appeared to have some fluctuation. PAHs contents in the soil were significantly correlated to soil properties such as soil organic matter, indicating that soil organic matter is an important factor for the distribution of PAHs. Molecular marker index analysis showed that PAHs mainly came from oil source.
