Simultaneous multiresidue analysis of 41 pesticide residues in cooked foodstuff using QuEChERS: Comparison with classical method.

摘要: The principal objective of this study was to develop a simple multiresidue method involving quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction for the identification quantification 41 pesticide residues in cooked foodstuffs including potatoes, radishes, rice using GC-μECD. analytes were subsequently confirmed via GC-MS. results then compared classical established by KFDA. quantitation individual pesticides based on matrix-matched calibration curves with correlation coefficient excess 0.993 selected herein. Using QuEChERS, mean recoveries ranged between 68.6 130.0% majority tested pesticides; however, exhibited low dichlofluanid, tetraconazole, oxadixyl, fenbuconazloe, paclobutrazol. After LODs LOQs 0.004 0.3μg/kg 0.0125 1.0μg/kg, respectively. proposed applied successfully determine residue levels foodstuffs, none samples contained detectable amounts residues.
