摘要
综述了城市土壤中重金属污染的来源、含量分布、化学形态、积累的生物效应及污染修复等近几年来的研究进展,以期为相关研究、环境决策和环境管理提供参考。
Urban soils are an important part of the urban eco-environment. With the development of urbanization, more and more attention has been given to the influence of heavy metal pollution of urban soils on urban eco-environment and human health. Soils in urban areas are deeply contaminated by urban sewages, garbages, waste gases from automobiles and industry. It is therefore an urgent need to study the heavy metal pollution of soils in urban areas and its impacts on eco-environment on the basis of introducing the definition and basic characteristics of urban soils, the progress of the study on pollutant source, content distribution, chemical configuration and biological accumulation effects of heavy metal pollution in urban soils in recent years is reviewed, and the perspective of the research on heavy metal pollution of urban soils is discussed.
