摘要
为深入了解水环境中邻苯二甲酸酯(PAEs)污染研究的发展现状,从Web of Science(WoS)核心合集中检索2000-2024年间所有相关研究文献,采用CiteSpace 6.2.R6(Advanced版本)软件进行可视化分析,对水环境中PAEs污染研究领域的国内外学者总发文量变化、主要发文机构和期刊、高共被引文献进行了分析和汇总,揭示了该领域知识基础特征以及研究热点和趋势。结果表明:该领域发文量呈上升趋势,2013年后发文量增长迅速。从研究实力上看,我国发表的论文数量最多(238篇,占总发文量的49.1%),具有明显优势,以中国科学院、南京大学为主的研究机构在该领域发文量最高。关键词分布中“PAEs”是最大的节点,“ecological risk assessment”“sediment”和“exposure”等高频词逐渐出现,突现强度最高的关键词为“degradation”。该领域的研究内容主要包括:区域范围内PAEs污染状况调查、PAEs的来源、降解机制以及生态风险评估。随着研究的深入,气候因素对PAEs空间分布的影响、PAEs与其他污染物在多介质的混合污染、迁移转化等环境归趋机理的揭示受到更多关注。
To comprehend the current state of phthalate esters(PAEs)pollution in aquatic environments,an exhaustive review of pertinent scholarly literature spanning from 2000 to 2024 was conducted utilizing the Web of Science Core Collection.Employing CiteSpace software 6.2.R6(Advanced Version),an in-depth analysis was performed to delineate the aggregate publication count from both global scholars,main institutions and journals,and highly cited literature in the field of PAEs pollution in water environment.This comprehensive analysis elucidated the intellectual foundation,research focal points and emerging trends within this domain.The volume of publications in this field existed an upward trajectory,particularly after the year of 2013.Notably,China contributed the highest number of published papers(238,accounting for 49.1%of the total),showing a significant research presence.Chinese research institutions,notably the Chinese Academy of Sciences and Nanjing University,led the field in terms of publication output.Keyword analysis revealed“PAEs”as the largest node,while terms such as“ecological risk assessment”,“sediment”and“exposure”gained prominence.Moreover,“degradation”emerged as the keyword with the strongest citation bursts.Research endeavors in this field mainly include investigation of PAEs contamination levels within the region,sources,degradation mechanisms,and ecological risk assessment.The future research will underscore the influence of climate factors on the spatial distribution of PAEs,elucidate environmental fate mechanisms such as mixed pollution,and scrutinize the migration and transformation of PAEs across various media,as well as the co-occurrence of PAEs with other pollutants.
