Abstract

ABSTRACT The aim of this study was to develop a convenient, fast, effective and safe analytical method (QuEChERS) to determine 198 pesticide residues in multi-source date palm fruits using gas chromatography-tandem mass spectrometry (GC-MS/MS). The calibration curves for most pesticides were linear in the range of 15–150 µg/kg, with r2 values higher than 0.9934 and the relative standard deviation for all pesticides was ≤20%. The mean recovery rate of pesticides was 70–120% and limits of detection (LODs) and limits of quantification (LOQs) were in the range of 5–14 µg/kg and 14–40 µg/kg, respectively. The validated procedure was used to monitor pesticide residues in 30 fresh date samples. It could be concluded that the modified QuEChERS extraction method was efficient in analysing pesticide residues in dates palm and none of the samples contained residues above the MRLs.

采用改进的QuEChERS法和GC-MS/MS法测定枣中农药残留

摘要建立一种简便、快速、有效、安全的气相色谱-串联质谱联用技术(GC-MS/MS)测定多源枣椰果中198种农药残留的方法。在15 ~ 150µg/kg范围内，大多数农药的校准曲线呈线性，r2值均大于0.9934，所有农药的相对标准偏差均≤20%。平均回收率为70 ~ 120%，检出限为5 ~ 14µg/kg，定量限为14 ~ 40µg/kg。采用该方法对30份新鲜枣样品进行农药残留监测。结果表明，改进的QuEChERS提取方法对红枣中农药残留量的分析是有效的，所有样品的农药残留量均不超过最大残留限量。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
