污水中新兴污染物的非靶向筛查研究进展

Research progress of identification of emerging contaminants in wastewater using non-target screening

大量的新兴污染物(ECs)随污水排放入自然环境中,对水生生物和水质安全造成了潜在的威胁。污水中新兴污染物的识别,是研究污染物迁移转化过程、毒性效应的前提。基于色谱-高分辨率质谱的非靶向筛查技术能够实现复杂水环境中新兴污染物的高通量测定。综述了现有非靶向筛查技术在识别污水中的新兴污染物的研究进展,主要包括样品的预处理方法,色谱-高分辨率质谱仪器测定方法与数据处理的过程及参数优化,非靶向识别新兴污染物的应用进展和发展趋势等,可为污水中新兴污染物的识别提供方法学参考。

A large quantitative of emerging contaminants(ECs)are discharged into natural water body with treated wastewater,which are posing a potential threat to the aquatic organisms and safety of water quality.The identification of ECs in sewage is the prerequisite for studying the migrationand transformation process and toxic effects of polluta-nts.High-throughput identification of ECs in complex water environment has been realized by nontarget screening ba-sed on chromatographic-high resolution mass spectrometry.The current research progress of nontarget screening in identifying ECs in wastewater were reviewed,which included the sample pretreatment method,the determination me-thods by chromatography-high resolution mass spectrometry,the data processing and parameter optimization,the exi-sting applications and future development directions of identification of ECs by non-target screening.The review could provide methodological reference for the identification of emerging pollutants in wastewater.
