基于CiteSpace的PPCPs研究现状及热点可视化分析

Research Status and Hotspot Visualization Analysis of PPCPs Based on CiteSpace

摘要: 目的：利用可视化软件CiteSpace分析药物及个人护理品(pharmaceuticals and personal care products, PPCPs)领域最近十年间的发展历程、研究现状和研究热点，为后续对该类新兴污染物的深入研究提供参考。方法：数据来源为Web of Science (WOS)数据库中的核心文集，检索时间为2011~2021年，检索词为PPCPs，共得到有效文献1668篇，利用CiteSpace软件进行国家、机构和作者的合作分析、关键词聚类和突发性分析。结果：PPCPs领域发文量最多的国家是中国，研究机构主要是中国科学院和清华大学，核心学者52人；关键词聚类分析显示PPCPs领域的主要研究热点为其在自然环境中主要的赋存形式和对生态的影响、进入环境的归宿以及环境中典型的抗生素类药物。关键词爆发性检测显示，目前主要研究的是具有代表性的抗生素类药物在环境中的降解情况以及是否对人体产生影响。

Abstract: Objective: To analyze the development history, research status and research hotspots in the field of pharmaceuticals and personal care products (PPCPs) in the last decade by using the visualization software CiteSpace, and to provide a reference for the subsequent in-depth research on this type of emerging contaminants. Methods: The data source was the core collection in the Web of Science (WOS) database, searched from 2011~2021, with the search term PPCPs, and a total of 1668 valid documents were obtained. Use CiteSpace software for collaborative analysis, keyword clustering, and burst analysis by countries, institutions, and authors. Results: The country with the largest number of publications in the field of PPCPs is China, and the research institutions are mainly the Chinese Academy of Sciences and Tsinghua University, with 52 core scholars; keyword clustering analysis shows that the main research hotspots in the field of PPCPs are their main fugitive forms in the natural environment and their impact on ecology, the fate of entering the environment, and the typical antibiotic drugs in the environment. The keyword burst detection shows that the main research is currently focused on the degradation of representative antibiotics in the environment and whether they have any effect on humans.
