Abstract

Food-derived agricultural chemical residues (FACRs) accumulate gradually in organisms and can damage their nervous system, endocrine system and reproductive system, posing significant harm. Currently, there is little literature on the detection of FACRs in waste wool fibers. In this paper, an ultrasound-assisted extraction-QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) cleanup-UPLC-Ms/Ms method was applied for the qualitative analysis and quantitative determination of trace FACRs in waste wool fibers with 0.2% formic acid-methanol as extraction solvent and multi-selective ion scanning. Using the external standard method, it was shown that the 13 target FACRs showed good linearity in the mass concentration range of 0.1-50 μg/kg. The limits of detection were 1.0- 10.0 μg/kg and the limits of quantification were 4.0-40.0 μg/kg. The recoveries of the 13 target FACRs ranged from 78 to 112.6% at the 5-, 10- and 20-fold detection limit spiked levels, and the intra- or inter-day relative standard deviations were 2.05-6.98% or 1.98-6.99%, respectively. This method satisfied the detection requirements and can be used in applications.

利用超声辅助萃取-QuEChERS净化-UPLC-MS/MS首次检测废羊毛纤维中的食品衍生农用化学品残留。

从食物中提取的农用化学品残留物（FACRs）会在生物体内逐渐积累，损害生物的神经系统、内分泌系统和生殖系统，造成重大危害。目前，有关废羊毛纤维中 FACRs 检测的文献很少。本文采用超声辅助萃取-QuEChERS（Quick, Easy, Cheap, Effective, Rugged, Safe）净化-UPLC-Ms/Ms方法，以0.2%甲酸-甲醇为萃取溶剂，多选择离子扫描，对废羊毛纤维中的痕量FACRs进行了定性和定量分析。结果表明，13 种目标 FACRs 在 0.1-50 μg/kg 质量浓度范围内线性关系良好。检测限为 1.0-10.0 μg/kg，定量限为 4.0-40.0 μg/kg。13种目标化合物在5倍、10倍和20倍检出限添加水平下的回收率为78%～112.6%，日内或日间相对标准偏差分别为2.05%～6.98%或1.98%～6.99%。该方法符合检测要求，可在应用中使用。

期刊介绍： The Journal of Chromatographic Science is devoted to the dissemination of information concerning all methods of chromatographic analysis. The standard manuscript is a description of recent original research that covers any or all phases of a specific separation problem, principle, or method. Manuscripts which have a high degree of novelty and fundamental significance to the field of separation science are particularly encouraged. It is expected the authors will clearly state in the Introduction how their method compares in some markedly new and improved way to previous published related methods. Analytical performance characteristics of new methods including sensitivity, tested limits of detection or quantification, accuracy, precision, and specificity should be provided. Manuscripts which describe a straightforward extension of a known analytical method or an application to a previously analyzed and/or uncomplicated sample matrix will not normally be reviewed favorably. Manuscripts in which mass spectrometry is the dominant analytical method and chromatography is of marked secondary importance may be declined.
