This method was on the base of the sample preparation in few steps and high speed. Measurement of pesticide residues was carried out by gas chromatograph with electron capture detector. In this study, most of the pesticides showed a recovery in the range of 70% – 120%. Limit of detection (LOD) and limit of quantification (LOQ) for all pesticides were lower than 0.50 and 1.90 μg/kg respectively. chlorpyrifos was detected in studied samples at average concentration 3.22 μg/kg, which was lower …
