Quantification of organophosphate insecticides and herbicides in vegetable samples using the “Quick Easy Cheap Effective Rugged and Safe” (QuEChERS) method and a high-performance liquid chromatography-electrospray ionisation-mass spectrometry (LC-MS/MS) t

► QuEChERS and LC-MS/MS were used for analysis of 18 pesticides in vegetable samples. ► This method was accurate (⩾99.5%), and it exhibited LOD in the ranged of 0.006-0.091. ► The R2 (⩾0.9999) were less than 1% at the low μg kg−1 end of the method. ► Mean recoveries ranged between 94% and 102%, and RSD were below 10%. ► The presence of target pesticides was found in the range of 0.016 and 50.85 μg kg−1.
