1999-2020年核心期刊三卤甲烷与卤乙酸文献计量学统计

Bibliometrics analysis of trihalomethane and haloacetic acid in core journals from 1999 to 2020

采用文献统计学的方法对1999-2020年中国核心期刊中分别以三卤甲烷(Trihalomethanes,THMs)和卤乙酸(Haloacetic acids,HAAs)为主题词的文献进行统计分析,分别从期刊、关键词、研究方向、前体物种类、研究水体、发文机构、基金等角度进行了探讨。结果表明:我国消毒副产物(Disinfection by-products,DBPs)领域的文献发文量总体呈上升趋势,国家自然科学基金为THMs和HAAs研究的主要资助者,大分子天然有机物(Natural organic matter,NOM)中腐殖酸是研究最频繁的THMs和HAAs前体物质,饮用水水厂水为主要研究水体。氯消毒技术研究热度逐年升高;THMs和HAAs研究热点集中在影响因素、控制措施、生成特性、变化规律、分析测定和健康风险等方面。揭示近20几年DBPs研究热点和趋势,为今后环境科学领域中DBPs深入研究工作提供一定参考和依据。

This paper used the method of bibliometrics analysis to analyze the literatures with main titles of trihalomethane(THMs)and haloacetic acid(HAAs)in Chinese core journals from1999 to 2020,and discussed from the perspectives of journals,key words,research directions,precursors species,research water bodies,publishing institutions and funds,etc.Results showed that the number of literatures published in the field of disinfection by-products(DBPs)in our country was generally on the rise.The THMs and HAAs research was primarily funded by the National Natural Science Foundation of China.Among the macromolecule natural organic matter(NOM),humic acid was the most frequently studied THMs and HAAs precursors.The drinking water of water plant was the main research water.Chlorine disinfection methods have increased year by year.The research hotspots of THMs and HAAs focus on influencing factors,control measures,generation characteristics,variation rules,analysis and measurement,and health risks.This study revealed the research hotspots and trends of DBPs in the past 20 years,and provided a certain reference and basis for further DBPs research in the field of environmental science in the future.
