Pesticides are among the most important contaminants worldwide due to their wide use, persistence, and toxicity. Their presence in soils is not only important from an environmental point of view, but also for food safety issues, since such residues can migrate from soils to food. However, soils are extremely complex matrices, which present a challenge to any analytical chemist, since the extraction of a wide range of compounds with diverse physicochemical properties, such as pesticides, at trace levels is not an easy task. In this context, the QuEChERS method (standing for quick, easy, cheap, effective, rugged, and safe) has become one of the most green and sustainable alternatives in this field due to its inherent advantages, such as fast sample preparation, the minimal use of hazardous reagents and solvents, simplicity, and low cost. This review is aimed at providing a critical revision of the most relevant modifications of the QuEChERS method (including the extraction and clean-up steps of the method) for pesticide-residue analysis in soils.
由于其广泛的使用、持久性和毒性，农药是全球最重要的污染物之一。它们在土壤中的存在不仅从环境角度来看很重要，而且对于食品安全问题也很重要，因为这些残留可以从土壤迁移到食物中。然而，土壤是极其复杂的基质，这对任何分析化学家来说都是一个挑战，因为要从土壤中提取痕量水平的具有不同物理化学性质的广泛化合物，如农药，并不是一件容易的事。在这种情况下，QuEChERS 方法（代表快速、简单、廉价、有效、耐用和安全）因其固有优势，如快速样品制备、危险试剂和溶剂的最小使用、简单性和低成本，已成为该领域最绿色和可持续的替代方法之一。本文旨在对 QuEChERS 方法（包括方法的提取和净化步骤）在土壤中农药残留分析方面的最相关修改进行批判性综述。
