摘　　要：近年来,环境污染问题愈发严重,已引发全球广泛关注。为评估不断变化的污染情况和潜在的环境影响,亟需建立快速、精确和可靠的方法对污染物进行定性、定量分析。常压质谱(AMS)技术能够在敞开环境下,无需样品预处理即可对痕量环境污染物进行原位、实时、快速分析。本文主要基于不同离子化技术,从电喷雾离子源(ESI)、大气压化学电离源(APCI)以及相关联用技术的角度,重点总结常压质谱技术在环境水样污染物检测中的应用情况,并对其在污染物检测领域的发展前景进行展望。Along with the industrial development and human society progress,large number of pollutants have been discharged to induce the environmental pollution,which have attracted global attentions.To evaluate the environmental pollution and environmental effects,the fast,accurate,and reliable analytical methods are required for qualitative and quantitative analysis of pollutants.Ambient mass spectrometry(AMS)has the advantages of rapid,in-situ and real-time analysis of samples at ambient conditions,without any sample pretreatment.Herein,from the perspective of different ionization technologies,the applications of electrospray ionization mass spectrometry(ESI-MS),atmospheric pressure chemical ionization mass spectrometry(APCI-MS),as well as the corresponding coupling techniques for the detection of environmental water pollutants were reviewed.Finally,the development of ambient ionization mass spectrometry in the detection of environmental pollutants was summarized and prospected.
