摘要:

为深入了解淡水生态环境中微塑料污染的研究现状，利用VOSviewer和CiteSpace软件整理了Web of Science核心合集数据库中2010年1月至2024年3月在淡水生态环境领域已发表的微塑料污染研究成果，从年发文量、来源期刊、作者/研究机构/国家的分布与合作关系、关键词聚类、关键词突现和时区视图等方面进行分析。结果表明:(1)年发文量自2018年以来呈爆发性增长，文章多为高质量产出，中国在该领域的研究成果居世界第一，其次是美国；研究机构方面，中国科学院发文量第一，中国科学院大学同各机构之间有着紧密合作关系，高校是高产出机构；研究学者中，华南农业大学的王俊发文量最多，其科研团队与新南威尔士大学以倪丙杰为中心的科研团队有着较为广泛的合作交流。(2)研究内容聚焦典型淡水生态环境中微塑料的来源分析、丰富度、空间分布、聚合物检测技术、治理工艺等方面，探究暴露在淡水生态环境中的微塑料与其他污染物的相互作用，以及其在淡水水生生物体内富集的毒性效应，甚至进入食物链、生态系统对人类的危害。(3)当前该领域研究处于快速发展阶段，前沿研究热点仍聚焦在微塑料的污染来源、分布特征及其与其他污染物的复合污染等方面，未来将深入开展微塑料的监测、检测、治理技术以及生态风险评估方向的研究。综上所述，本研究为深入了解淡水生态环境微塑料污染研究热点演变提供了客观、较为全面的见解，可为未来的研究方向提供参考思路。

Abstract:

To gain an in-depth understanding of the research status of microplastic pollution in freshwater environment,VOSviewer and CiteSpace were used to sort out the research results in this field that were published from January 2010 to March 2024 in the Web of Science Core Collection.The annual number of publications,journals,distribution and cooperation of authors/research institutions/countries,keyword clustering,bursts and time distribution were analyzed.The results were yielded as follows.(1)The annual number of publications had surged since 2018,most of which were high-quality outputs.China's research results in this field ranked first in the world,followed by the United States.Among the research institutions,the Chinese Academy of Sciences had the largest number of publications,and the University of Chinese Academy of Sciences had a close cooperation relationship with various institutions.Universities were high-output institutions.Among the researchers,Wang Jun at the South China Agricultural University published the most papers,and his research team had extensive cooperation and exchanges with the research team led by Ni Bingjie at the University of New South Wales.(2) The research contents focused on the source analysis,richness,spatial distribution,polymer detection technology and treatment process of microplastics in typical freshwater ecological environment,the interactions between microplastics and other pollutants in freshwater ecological environment,the toxic effects of enrichment in freshwater aquatic organisms,and even the harm to humans caused by entering the food chain and ecosystems.(3)At present,the research in this field experienced rapid development,and the cutting-edge research hotspots still focused on the source,distribution characteristics and compound pollution with other pollutants.The research on the monitoring,detection,treatment technology and ecological risk assessment of microplastics would be carried out in the future.In summary,this study provides an objective and comprehensive insight into the evolution of microplastic pollution in freshwater ecological environment and can provide reference for future research directions.
