Abstract
为探究淡水中微塑料的研究现状、热点和趋势,以 Web of Science(WOS)核心数据库为数据源,采用Citespace、VOSviewer和Bibliometrix等文献计量软件及Scimago graphica可视化工具,对2007 年至2022 年期间发表的淡水中微塑料相关文献进行可视化分析.结果表明,自 2014 年起淡水中微塑料相关研究的发文量呈指数增长.中国在该领域具有较强的学术影响力,发文量、论文引用数、H指数等位居首位.发文量最高的作者来自于华东师范大学、中国科学院、中国科学院大学,华东师范大学是该领域主要的研究机构.高产期刊为Science of the Total Environment.热点高频关键词包括微塑料、污染、淡水、沉积物和污水处理厂等.关键词聚类表明,淡水中微塑料研究的热点主题包括"微塑料的吸附、来源和降解""微塑料鉴定""微塑料在淡水环境中的污染""微塑料在生物体内的累积"和"微塑料的毒性作用"5 个方面.关键词突现分析显示,偏远地区和特殊地理条件中微塑料污染及纺织品洗涤释放的纤维微塑料问题被视为该领域研究的新趋势.未来研究应关注偏远地区和特殊地理等更大范围内微塑料污染及减少来源于纺织品洗涤产生的微塑料.
In order to explore the current status,hotspots and trends of research on microplastics in freshwater.Using the core database of Web of Science(WOS)as data sources,and using the bib-liometric software such as Citespace,VOSviewer,Bibliometrix and visualization tools such as Scima-go graphica to conduct a visual analysis of microplastics-related literature published in freshwater from 2007 to 2022.The results showed that the number of publications related to microplastics in freshwater has increased exponentially since 2014.China has strong academic influence in this field,ranking first in terms of publications,paper citations,H-index,etc.The author with the highest publications came from East China Normal University,and the main research institutions in this field were the Chinese Academy of Sciences,University of the Chinese Academy of Sciences,and East China Normal University.The high-yield journal was Science of the Total Environment.The hot frequency keywords included microplastics,pollution,freshwater,sediments,and sewage treatment plants.Keyword clustering showed that the hot topics in microplastics research in freshwa-ter include"adsorption,sources,and degradation of microplastics""identification of microplastics""pollution of microplastics in freshwater environment""accumulation of microplastics in organisms",and"toxic effects of microplastics",etc.Keyword bursting analysis showed that microplastic pollu-tion in remote areas and under special geographic conditions,as well as the issue of fiber microplas-tics released from textile washing,are regarded as new trends in research in this field.Future re-search should focus on microplastic pollution in larger ranges,including remote areas and special ge-ographies,and reducing microplastics from textile washing.
