摘要
抗生素与内分泌干扰物是近些年全球广泛关注的新污染物。基于中国知网和Web of Science数据库检索河流中抗生素与内分泌干扰物环境行为的研究动态,使用CiteSpace和VOSviewer软件进行文献计量学分析。结果表明:2000—2022年共发表该研究领域相关文献2085篇,包括399篇中文和1686篇英文文献,年发文量呈上升趋势且在过去5年迅速增长。英文文献涉及全球96个国家和2022所研究机构,中国和美国的国际表现力较为突出,发文量分别为773和251篇,其中中国科学院大学发文量位居第一且与国内外机构合作紧密。发文的期刊以环境科学类为主,多学科交叉融合,其中中英文期刊分别以《环境科学》和Science of the Total Environment发文量最多。关键词聚类与时区图谱表明,该领域当前以区域性研究为主,双酚A、壬基酚、有机氯农药等内分泌干扰物与四环素类、磺胺类、喹诺酮类等抗生素在河流中的污染特征研究较为广泛,而针对激素类内分泌干扰物的研究仍不充分,污染物在河流中的迁移、转化、去除等机理研究是当前主要方向。突现词结果表明,过去20年该领域研究可分为3个阶段,早期研究以分析方法和河流中赋存特征等污染调查为主,中期研究以探究污染物的运移归趋为主,近年来研究由生态风险评估转向河流水生态健康管理服务,发展符合区域特征的污染物管控策略与去除技术是当前热点和未来趋势。此外,由抗生素污染衍生的耐药性问题引起全球关注,抗生素抗性基因的产生和传播机制及生态与健康风险也是当前热点和未来关注的重点。
Antibiotics and endocrine disruptors are emerging contaminants that have attracted global attention in recent years.Based on the databases of China National Knowledge Infrastructure(CNKI)and Web of Science(WoS),relevant literature on the environmental behavior of antibiotics and endocrine disruptors in rivers was retrieved.CiteSpace and VOSviewer software were used for bibliometric analysis and visualization display.The results showed that a total of 2085 relevant papers were searched in CNKI and WoS from 2000 to 2022,including 399 Chinese articles and 1686 English articles.The research in this field showed an upward trend and increased rapidly in the past five years.The English literature involved 96 countries and 2022 institutions,and the international performance of China and the United States was the most prominent,with 773 and 251 articles published respectively.The University of Chinese Academy of Sciences ranked first in publications and cooperated closely with institutions at home and abroad.The journals published were mainly in the field of environmental science with interdisciplinary integration,with Environmental Science(Chinese)and Science of the Total Environment topping the publications.The keywords clustering and time zone maps showed that regional research was mainly focused at present.The pollution characteristics of endocrine disruptors including bisphenol A,nonylphenol and organochlorine pesticides,and antibiotics including sulfonamides,tetracyclines and quinolones in rivers were most widely studied,while research on hormonal endocrine disruptors was still insufficient.Study on the migration,transformation and removal mechanisms of the pollutants in rivers was the main trend.The results of keywords of strongest citation bursts indicated that the research in this field over the past 20 years could be divided into three stages.In the early stage,research mainly focused on analysis methods and investigation on the occurrence and characteristics of the contaminants in rivers.In the mid-term,studies
