摘要
氯化石蜡(CPs)是一类新型持久性有机污染物,也是我国环境介质和生物体污染最严重的卤代有机污染物(OHPs)之一,近年来引起研究者高度关注。由于环境样品基质较为复杂,且其中CPs的含量水平相对较低,CPs需经提取与净化后才能进行仪器检测。CPs的同系物和异构体多达数千种,消除CPs单体以及其它OHPs的质量干扰是仪器检测CPs的关键。高分辨质谱(HRMS)具有相对较高的分辨率,能够解决这一关键问题。本文介绍了环境样品中CPs的提取与净化方法,主要从气相色谱-高分辨质谱(GC-HRMS)和液相色谱-高分辨质谱(LC-HRMS)两个方面阐述HRMS在CPs分析中应用的研究进展,总结了目前CPs分析方法中存在的问题,并对未来的发展趋势进行了展望。
Chlorinated paraffins(CPs)are a new class of persistent organic pollutants and have aroused great concern of many environmental scientists due to their ubiquity in various environmental media and biotas.Given their relative low levels in environmental samples,CPs need to be enriched and cleaned up before instrumental analysis.CPs consist of thousands of congeners and isomers,thus posing grand challenges to eliminate the mass interference by homologues and other organohalogen compounds during instrumental examination.Fortunately,high-resolution mass spectrometry(HRMS)owns the powerful ability to solve this key problem owing to its high mass resolution.This review introduced the methods of pretreatment and instrumental analysis of CPs-containing samples in the environment,mainly illustrating the application of gas chromatography and liquid chromatography coupled with HRMS(i.e.GC-HRMS and LC-HRMS).The existing issues and prospects of future study were also discussed.
