Soil is a primary sink and reservoir for pesticides pollution and one of the priority objects in terms of pesticides safety guidelines. Pesticides’ analysis in soil is a field of research which is in constant development facing numerous challenges such as the increasing amount and variety of analytes and their combinations, as well as the increasing demand for faster, simpler, more accurate and multiresidue analysis. This review provides the summary of studies on pesticides analysis in soil based on chromatography-coupled methods published between 2015 and 2022. We discuss the shift toward faster, greener, and simpler alternatives to conventional techniques, application of sample preparation and detection methods to targeted and untargeted pesticide analysis, as well as the developments in stereoselective determination of chiral pesticides. The sample preparation methods such as solid-phase extraction, dispersive solid-phase extraction, and derived methods, as well as the recent trends and developments in chromatographic separation of pesticides are covered in this review. For sample preparation, the QuEChERS method is replacing other techniques and has proved to be efficient in both screening and accurate quantification in multiresidue analysis. Shift towards minimal sample preparation is supported by a wider application of highly sensitive and selective separation and detection systems such as LC-MS/MS. The features of different methods of sample preparation and detection are discussed with focus on optimal parameters, advantages, and drawbacks. The optimal parameters of sample preparation methods were summarized based on respective publications, which makes the review a useful tool for method development and further investigations.

土壤中农药的色谱测定:分析和样品制备的当前趋势

土壤是农药污染的主要汇和库,是农药安全指南的重点对象之一。土壤中的农药分析是一个不断发展的研究领域,面临着许多挑战,例如分析物及其组合的数量和种类不断增加,以及对更快、更简单、更准确和多残留分析的需求不断增加。这篇综述总结了 2015 年至 2022 年间发表的基于色谱耦合方法的土壤农药分析研究。我们讨论了向更快、更环保、更简单的传统技术替代方案的转变,样品制备和检测方法在靶向和非靶向农药分析,以及手性农药立体选择性测定的发展。本综述介绍了固相萃取、分散固相萃取和衍生方法等样品制备方法,以及农药色谱分离的最新趋势和发展。对于样品制备,QuEChERS 方法正在取代其他技术,并已被证明在多残留分析中的筛选和准确定量方面都非常有效。高灵敏度和选择性分离和检测系统(如 LC-MS/MS)的更广泛应用支持向最少样品制备的转变。讨论了不同样品制备和检测方法的特点,重点讨论了最佳参数、优点和缺点。根据各自的出版物总结了样品制备方法的最佳参数,
