High resolution mass spectrometry(HRMS) has been widely applied in the field of water quality detection and analysis. This paper summarized the classification and characteristics of HRMS, and described the technical advantages of HRMS. The procedure of target, suspected and non-target HRMS high-throughput screening directed at improving the efficiency of pollutant screening in water environment was introduced, which included a database of target compounds based on different categories and a database of particular pollutants with local watershed characteristics. The limitations of high resolution pre-processing technology and the lag of screening software standardization were analyzed,and the application of HRMS screening technology in ensuring urban water supply and drainage safety was prospected.
