土壤重金属污染是危害性极大的全球性环境问题,钝化修复是治理污染土壤较为实用的绿色经济策略之一.为分析土壤重金属污染钝化修复研究现状,基于Web of Science核心合集数据库,采用文献计量学方法对2000-2021年土壤重金属钝化研究论文相关数据进行可视化分析.结果表明,在2000-2021年全球土壤重金属钝化领域的发文数量整体呈上升趋势,Environmental Science and Pollution Research、Chemosphere、Journal of Hazadous Materials以及Science of the Total Environment等杂志刊发该领域的研究内容较多,国家级基金等是土壤重金属钝化研究领域的主要资助来源.关键词聚类分析显示,镉污染修复是重金属钝化修复领域较受重视的问题之一,中国科学院、中国农业科学院农业农村部环境保护科研监测所以及中国科学院大学等单位是土壤重金属钝化研究领域的代表性机构.未来的研究应着重于钝化材料修复污染土壤的机理,可同时修复多种重金属的新型钝化材料筛选,以及结合重金属低积累品种或栽培措施等方面,提高修复效果,降低修复成本.
Bibliometric analysis of research on passivation remediation of heavy metal contaminated soil based on Web of Science
Soil heavy metal pollution is a very harmful global environmental problem,passivation remediation is one of the more practical green economic strategies to control polluted soil.In order to analyzed the research status of the passivation remediation of soil heavy metal pollution,based on the Web of Science Core Collection database,literature metrology method was used to make a visual analysis of the data related to the research papers on soil heavy metal passivation from year 2000 to 2021.The results revealed that the number of publications in the field of soil heavy metal passivation in the world has been on the rise from year 2000 to 2021,and the relevant literature was found to be primarily published in quality journals,including Environmental Science and Pollution Research,Chemosphere,Journal of Hazadous Materials and Science of the Total Environment.In terms of funding,national funds appear to be the main source of financial support for research in this field.Keyword cluster analysis revealed that the research of heavy metal passivation in soil mainly focuses on the remediation of cadmium pollution.The remediation of contaminated soil can be achieved by using passivating agent to fix heavy metals in the soil.Then several research institutions,including Chinese Academy of Sciences,Agro-Environmental Protection Institute of Ministry of Agriculture and Rural Affairs,Ministry of Agriculture and Rural Affairs,and University of Chinese Academy of Sciences are committed to research in this field.Future research should be focus on deciphering the mechanism of passivation materials in remediating contaminated soils,selecting new materials that can passivate and repair multiple heavy metals contamination,and collaboratively using low accumulation of heavy metals varieties or with cultivation measures techniques to improve the repair effect and as well as reduce the cost.
