Chromatography coupled to mass spectrometry has become an important tool for determining emerging organic contaminants (EOCs) in environmental samples such as aquatic organisms. Sample treatment, which includes extraction and clean-up, continues to play an important role in the analysis of complex matrices. Indeed it often becomes a bottleneck in the compromise between time and efficiency when obtaining suitable extracts for analysis. This article focuses on the state of the art in the treatment of aquatic organism samples for determining EOCs. A review is carried out of the most recent relevant publications from 2011 up to the present, in which new methods for determining EOCs in aquatic organisms were developed. The most common extraction techniques employed in these studies, like pressurised liquid extraction, solid-liquid extraction, QuEChERS, microwave-assisted extraction and matrix solid-phase extraction along with the subsequent clean-up steps, are also examined. The most important parameters involving extraction and clean-up are discussed.

用于确定水生生物中新兴有机污染物的样品处理

色谱与质谱联用已成为确定环境样品(例如水生生物)中新出现的有机污染物(EOC)的重要工具。样品处理(包括提取和净化)在复杂基质的分析中继续发挥重要作用。实际上,当获得合适的提取物进行分析时,它常常成为时间和效率之间折衷的瓶颈。本文重点介绍处理水生生物样品以确定EOC的最新技术。回顾了从2011年至今的最新相关出版物,其中开发了确定水生生物中EOC的新方法。这些研究中采用的最常用的提取技术,例如加压液体提取,固液提取,QuEChERS,还研究了微波辅助萃取和基质固相萃取以及随后的净化步骤。讨论了涉及提取和净化的最重要参数。
