摘要
分析并阐述了中国部分主要城市土壤重金属污染的来源、危害、污染现状及污染特征,以及随着中国城市化进程的加快,今后应对于城市土壤重金属污染的研究引起广泛的关注。城市土壤重金属的来源非常复杂,目前的研究主要局限于定性描述和相关分析,因此在治理方面应根据城市土壤污染的特点及所处环境进行对策研究,并应结合人体健康评估和土地利用方式而制定相应的法规和标准。此外,对重金属的来源进行定量分析,对于控制日益严重的城市土壤重金属污染具有重要意义,也是今后土壤重金属研究分析的重点。
This paper elaborated the origin, the harm, the present situation and the characteristics of heavy metal pollution of the urban soil in some areas of China. With the quickening pace of our country＇s urbanization course, widespread attention upon the urban soil heavy metal pollution＇s research should be aroused. Nowadays research mainly focuses on qualitative description and correlative analysis since the research on urban soil heavy metal pollution is very complex. Researchers should act according to the characteristic of the city soil pollution and the environment it locates to conduct the countermeasure research, and the government should unify the human body health appraisal and the land utilization way to make the corresponding laws, regulations and the standards. Besides, quantitative analysis of source of heavy metal pollution is essential to controlling the more and more serious situation of urban soil heavy metal pollution and is also the emphases of filture analysis of soil heavy metal pollution.
