溶解性有机质(Dissolved organic matter,DOM)是广泛分布于各类环境介质中的复杂有机混合物,对污染物和营养元素的环境行为以及全球碳循环具有深远影响.傅里叶变换离子回旋共振质谱(Fourier transform ion cyclotron resonance mass spectrometry,FT-ICR MS)是当今研究有机混合物分子组成最为先进的质谱技术,对DOM的生态环境效应研究具有重要意义.为了解FT-ICR MS在环境科学、地球科学领域的研究现状、热点、趋势以及典型应用,基于Web of Science数据库并结合VOSviewer软件进行文献计量学可视化分析.结果表明:中国大陆在该研究领域的发文量最多,其次是美国.在学科上是以环境科学为发文量最多;在期刊上是以Environmental Science & Technology期刊发文量最多.国内高产作者为史权教授与何晨博士,国外高产作者为Thorsten Dittmar教授;相关研究热点关键词涉及空气、地下水、生物群落、饮用水消毒、水处理等为主.此外,相关典型应用旨在帮助人们提高对DOM高通量、非靶向定性分析的认识.首次报道了 FT-ICR MS在环境地球科学中的文献计量学研究,指出了当前的研究现状与热点,彰显了 FT-ICR MS在环境地球科学研究方面的巨大潜力.
Application of Fourier Transform Ion Cyclotron Resonance Mass Spectrometry in Molecular Characterization of Dissolved Organic Matter:A Bibliometrics-Based Visual Study
Dissolved organic matter(DOM)is composed of complex organic mixtures in diverse environments and plays critical roles in governing the environmental fate and transport of pollutants and nutritious elements and the global carbon cycle.Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS)is the most advanced mass technique for the molecular composition of organic matter,with great importance in elucidating the ecological and environmental significance of DOM.This bibliometrics study based on Web of Science database was performed to visually analyze the current status,hot spots,trends and typical applications of FT-ICR MS in environmental earth science research.The results show that Mainland China has the largest number of publications in this field,followed by the United States.Environmental science is the most published among all disciplines with the most prolific journal,Environmental Science& Technology.The most productive domestic and foreign authors are Prof.Shi Quan,Dr.He Cen and Prof.Thorsten Dittmar in this field,respectively.The relevant research is mainly focused on air,groundwater,biological community,drinking water disinfection and water treatment.In addition,typical applications are reviewed to facilitate our understanding in the high-throughput and non-targeted qualitative analysis of DOM.For the first time,this bibliometrics study reports the current research status and hot spots of FT-ICR MS in the molecular characterization of DOM from diverse environments,highlighting its great potential in environmental earth science research.
