Persistent and Mobile Organic Compounds (PMOCs) are emerging pollutants in the environment that have only been rarely detected in previous years due to the lack of analytical techniques available for their analysis. These compounds, being very polar, are able to spread through the surface waters, and reach groundwaters and drinking water sources. The challenges in the analysis of these compounds in water include their poor extraction efficiencies from environmental matrices and weak retention in conventional chromatographic columns. As a result, the toxicity and environmental fate of PMOCs are largely unknown. This review will examine recent developments in sorbent and chromatographic column technologies, and other sample preparation strategies that will enable analysis of PMOCs and advance our knowledge on their fate and transport in the environment. In addition, analysis of these compounds in water via liquid chromatography with tandem mass spectrometry (LC–MS/MS) are discussed in this review.

捕获难以捉摸的持久性和移动性有机化合物:新颖的样品制备和先进的分析技术

持久性和移动性有机化合物(PMOC)是环境中新兴的污染物,由于缺乏可用于其分析的分析技术,因此在前几年很少被检测到。这些化合物极具极性,能够在地表水中扩散,并到达地下水和饮用水源。分析水中的这些化合物所面临的挑战包括它们从环境基质中的萃取效率差以及在传统色谱柱中的保留能力弱。结果,人们对PMOC的毒性和环境命运知之甚少。这篇评论将探讨吸附剂和色谱柱技术的最新发展,以及其他样品制备策略,这些策略将有助于对PMOC进行分析,并增进我们对它们在环境中的命运和运输的了解。此外,本文还讨论了通过液相色谱-串联质谱法(LC-MS / MS)分析水中的这些化合物。
