中文摘要:根据国际标准,本文采用改良QuEChERS法与液相和气相色谱-三重四极杆质谱仪(LC-MS/MS和GC-MS/MS)对棉纤维中412农药残留进行定性和定量的分析,412种农药包括43种氨基甲酸酯类、16氯菊酯、27有机氯(OCS)、54种有机磷(OPS)、31种尿素衍生物、7多氯联苯(PCBs)、6新烟碱类农药和228种其他农药。本文根据欧盟标准进行优化和验证,证明了该方法的可靠性,平均回收率在70-120 %的可接受范围内,相对标准偏差均小于20%,除了3种气相色谱仪检测化合物和17种相色谱仪检测化合物的定量限为0.05mg/kg外,其他所有农药残留的定量限均为0.01mg/kg。
外文摘要:The new global concept is to care about textiles and clothes safety to improve the protection of the human health and the environment from the harmful pesticide residues. Very few articles have been published for determination of several pesticide classes in cotton fibers in one multi-residue method. A simple, efficient, sensitive, accurate, and reliable multi-residue method was developed for the determination of 412 residual pesticides in cotton fibers using modified QuEChERS method with Liquid and Gas Chromatography coupled to Triple Quadrupole Mass Spectrometer (LC-MS/MS & GC-MS/MS) for qualitative and quantitative analysis according to the international standards concepts. The developed method covered several pesticide classes, including 43 carbamates, 16 pyrethroids, 27 organochlorines (OCs), 54 organophosphorus (Ops), 31 urea derivatives, 7 Polychlorinated biphenyl (PCBs), 6 Neonicotinoid, and 228 other pesticides. Most of the target pesticides were listed in Oeko-Tex Standards, the EU Ecolabel for textile products, and the Egyptian recommendations of the Agricultural Pesticide Committee (APC-Egypt). The method optimization and validation were carried out according to the EU guidelines. The results were shown to be reliable where the corresponding average recoveries within the acceptable range of 70-120%; the relative standard deviations were less than 20%. The limit of quantitation (LOQ) of this method is 0.01mgkg(-1) all pesticides except for 3 GC-compounds and 19 LC-compounds which have LOQ of 0.05mgkg(-1).
