为了解土壤胶体影响重金属行为领域的研究现状和前沿动态,基于Web of Science(WoS)核心合集数据库,利用WoS自带分析工具、HistCite引文图谱分析软件、VOSviewer和Citespace可视化分析软件对1990~2021年之间土壤胶体影响重金属行为领域发表的文献进行了计量分析。结果表明,全世界在该领域的发文量逐年升高。我国相关研究起步较晚,但近些年呈现迅猛发展的势头。中国科学院是发文量最高的研究机构,在该领域具有较高的学术活跃度。发文量最高的期刊为Environmental Science Technology。主要研究学科为环境科学与生态学和环境科学。通过关键词聚类分析发现,该领域主要的研究主题为“土壤胶体颗粒粒径分级与重金属的形态分布”和“土壤胶体颗粒的迁移机制与迁移模型研究”。该领域现阶段的研究热点是研究工程纳米颗粒在土壤中的行为、迁移转化以及生物有效性。该研究结果对该领域研究方向、发展趋势和研究热点具有指导意义。未来有望利用场流分离技术结合单粒子ICP-MS等技术对土壤胶体与工程纳米颗粒之间发生的复杂的相互作用以及对工程纳米颗粒迁移归趋与环境命运的影响进行深入研究。
Abstract: 【Objective】With the rapid development of industrialization and urbanization, heavy metal pollution in soil has attracted worldwide attention. Natural soil colloids, as well as engineered nanoparticles introduced into soil by direct or indirect pathways, play an important role in the migration and bioavailability of heavy metals. However, there is a lack of research on the current status and frontier trends of soil colloids' effect on the behavior of heavy metals. 【Method】Based on the Web of Science (WoS) core collection database, a bibliometric study on the effect of soil colloids on the behavior of heavy metals during 1990~2021 was carried out using analysis tools self-provided by WoS, HisCite citation analysis software, VOSviewer and Citespace visual analysis software. 【Result】Results indicated that the number of publications increased steadily year by year worldwide, with an average increase of two publications per year. The research in this field started late in China but it showed a momentum of rapid development in recent years which may be due to a series of important measures for soil pollution control implemented in China. The countries and research institutions with the most publications in this field were the United States and the Chinese Academy of Sciences, respectively. Environmental Science & Technology was the most published journal. The major subjects involved in this field were the intersection of environmental sciences and ecology. The results of keywords cluster analysis indicated that “particle size fractionation and heavy metal speciation distribution of soil colloids”, “release, deposition of soil colloids and adsorption of heavy metals” and “migration mechanism and migration model of soil colloids” were the dominating research topics. Also, the first dominating research topic tended to describe the state of distribution and morphology of heavy metals in soil with different particle sizes. Furthermore, the second and third dominating research topics tended to focus on the dynamic process of release, migration and deposition of soil colloids, the binding effect of soil colloids on heavy metals and their cooperative transport behavior. The current research hotspot involves the study of the behavior, migration, transformation and bioavailability of engineered nanoparticles in soil using advanced characterization techniques such as field flow-fractionation technology. 【Conclusion】These results provide important insights into the research direction, growing trend and research hotspots in the field of soil colloids affecting the behavior of heavy metals. In the future, the application of field-flow fractionation technology combined with single particle inductively coupled plasma mass spectrometry or other technologies to further study the complex interaction between soil colloids and engineering nanoparticles should be prioritized. Also, the influence on the migration and environmental fate of engineered nanoparticles is expected to be a future research direction.
