随着城市化进程的加快，城市土壤中的多环芳烃（PAHs）污染日趋严重.本文从城市土壤中多环芳烃的分布和来源等方面综述了国内外取得的最新研究成果,对影响城市土壤多环芳烃分布的人为因素、自然因素，常见的多环芳烃源解析方法，以及城市土壤多环芳烃污染的风险评价进行了全面的阐述，尤其对地统计学在多环芳烃空间分析及风险评价上的应用进行了总结.最后，对未来城市土壤中多环芳烃研究的重点与发展趋势进行了展望.
With rapid urbanization, the contamination of polycyclic aromatic hydrocarbons (PAHs) has become one of the major factors threatening urban soil quality and human health. This paper summarized the current studies on the PAHs in urban soils, with the focus on the anthropogenic and natural factors affecting the distribution of PAHs in urban soils, analytical methods on the pollution sources of PAHs, risk assessment of urban soil contamination by PAHs, and especially, applications of geo-tatistics in the spatial analysis and risk assessment of PAHs. The potential issues and research trends about the PAHs contamination of urban soils were also discussed.
