城市土壤重金属分布特征和健康风险评价研究进展

Review on distribution characteristics and health risk assessment of heavy metals in urban soils

作为城市生产活动的载体,伴随城市化的快速发展,城市土壤的重金属污染问题日益严重,不断威胁着城市生态环境和人群健康,土壤重金属研究对城市的健康发展有着重要意义。文章归纳了国内外城市土壤重金属分布特征和污染来源的最新研究进展,从定性和定量角度评述了城市土壤重金属来源解析研究方法,全面阐述了城市土壤重金属健康风险评价方法,并总结了健康风险评价中的不确定性。在此基础上就城市土壤重金属来源解析和健康风险评价未来的研究趋势提出展望,以期为城市土壤重金属风险管理提供科学依据。

As the carrier of the city＇s production, the city＇s heavy metal pollution has become increasingly serious with the rapid development of urbanization, and constantly threaten the urban ecological environment and population health, therefore, the study of heavy metals in soils has great significance to the healthy development of the city. In this paper, the latest research progress on the distribution characteristics and pollution sources of heavy metals in urban soils at home and abroad was summarized, and the analysis study way of sources of heavy metals in urban soils was qualitatively and quantitatively remarked respectively. Then, the method of health risk assessment of heavy metals in urban soils was also expounded, and the uncertainty of health risk assessment was summarized in this paper. On the basis of that, the future research trend is put forward in terms of the analysis of the sources and the health risk assessment of heavy metals in urban soils, so as to provide a scientific basis for the risk management of heavy metals in urban soils.
