中文摘要：为了筛选出一个敏感、简单、快速、有效、可靠的复杂农产品基质中农药残留的分析方法，本文提出了复杂农产品基质农残检测分析方法的评价策略并采用韭菜样本进行验证。本文中大多数农药残留基质效应在-50%到-90%范围内，采用简单薄层色谱法评价清洗效果，验证后，结果吻合。此外，超过91%的残留物回收率在70-120%范围，检测限和定量限分别在0.1-3.5 ng/g和0.4-11.5 ng/g。本文的评价策略可用于多种复杂基质的农药残留或相关化合物的检测方法的评估，并可为分析方法的选择提供技术指导。
外文摘要：In order to choose a sensitive, selective, simple, rapid, cost-effective and reliable analytical method for a given complex sample, a strategy was proposed for the evaluation of an analytical approach to determining multi-pesticide residue in complex agricultural product matrices, using leek as an example. In this work, the matrix effect of most of pesticides were in the range of -50% to -90%. A simple thin layer chromatography (TLC) was used to evaluate the effect of cleanup. The results agree well with that of matrix effect described above. More than 91% of the investigated compounds achieved recoveries were in the range of 70-120%. The limits of detection and limits of quantification were in the range of 0.1-3.5 ng/g and 0.4-11.5 ng/g, respectively. The strategy can be used to analyze multi-pesticide residue or related chemicals in diverse agricultural product matrices to provide technical guidance in choosing an analytical approach.
