The analytes were extracted from five fruit and vegetable matrices using acetonitrile and subsequently cleaned up using primary secondary amine (PSA) or octadecylsilane (C18) as sorbent prior to GC analysis. The present methods provided sufficient sensitivity as reflected by the values of limit of detection (LOD) and limit of quantification (LOQ) of 0.4\u20137 and 1.2\u201320\u2009\u00b5g\/kg for GC\u2010IT\u2010MS\/MS and GC\u2010NPD. The recoveries were, on average, 68\u2013117 and 68\u2013121%, respectively, for three compounds by GC\u2010NPD and GC\u2010IT\u2010MS\/MS with intra\u2010day precision achieved with an RSD of 2.7\u201319.1%. The inter\u2010day precision was better than 15.1% as determined by GC\u2010NPD. The QuEChERS procedure, by using two sorbents (PSA and C18) and the matrix\u2010matched standards, gave satisfactory recoveries and RSD values in different matrices. IT\u2010MS acquisition provided higher specificity and selectivity for pesticides and better limit of detection and quantification. However, the repeatability and precision of NPD method were better compared with IT\u2010MS.
