摘要
针对城市土壤特性,对土壤中多环芳烃(polycyclic aromatic hydrocarbons,PAHs)污染方面的研究进行了分析与综述,归纳总结了城市土壤PAHs的含量、分布、来源、影响因子及污染评价。结果表明城市土壤PAHs含量在地区、时间上存在较大差异,其来源主要是人为源,同时还受到气候、土壤理化性质、土壤微生物作用及地表植物种类的影响,目前许多城市土壤PAHs存在一定程度的污染,需要尽快建立PAHs数据库,为城市土壤PAHs的污染预警及防治提供数据支持。
This paper summarized the concentration, distribution, source, influence factors and pollution assessment of polycyclic aromatic hydrocarbons （PAHs） in urban soil. The results showed that the concentration of PAHs in urban soil varied greatly in spatial and temporal scale, which was influenced by climate, soil physical and chemical properties, soil microbial activities and surface plant species. At present, a lot of urban soils were polluted by PAHs, so it is necessary to establish PAHs database as soon as possible in order toto provide data support for pollution prevention and control of PAHs in urban soil.
