Sample preparation in analytical chemistry can have considerable environmental impacts. This article highlights sampling and sample preparation methods relating to organic pollutants in water, which have been published over the last 2 years (2019 to present) and aim to address green chemistry concerns, such as solvent and reagent use and energy consumption. Samplers that combine analyte preconcentration with sampling are advantageous, whilst microextraction techniques continue to receive extensive research interest. These include solid-phase microextraction, microsolid-phase extraction, dispersive liquid–liquid microextraction, single-drop extraction, stir bar sorptive extraction, and QuEChERS. Developments have focused on the synthesis of novel sorptive materials for extraction applications and on alternative extraction setups. The provision of analytical methods, which are facile, effective, and green, continues to pose challenges and will require future innovations to be fully realized.

分析化学中的样品制备会对环境产生重大影响。本文重点介绍了与水中有机污染物有关的采样和样品制备方法，这些方法已在过去两年（2019年至今）中发布，旨在解决绿色化学问题，例如溶剂和试剂的使用以及能源消耗。将分析物预浓缩与采样相结合的采样器是有利的，而微萃取技术继续受到广泛的研究兴趣。这些方法包括固相微萃取，微固相萃取，液-液分散微萃取，单滴萃取，搅拌棒吸附萃取和QuEChERS。开发集中在用于萃取应用的新型吸附材料的合成以及替代的萃取装置上。
