In this research, 66 samples of tomatoes were collected from vegetables central market in Darr´aa city during the period extended between 20 October/2009 - 4 October/2010) to investigate the presence of 26 pesticide residues which belong to different chemical classes using Gas Chromatography instruments equipped with μECD, FPD, MSD detectors. QuEChERS extraction method was used for residue extraction from tomato samples. The detectors linearity and pesticide detection limits were determined for every pesticide studied, and the recovery for all pesticides ranged from 90.6 for fenvalerate to 105.5% for propargite. Results showed that 56.1% of tomato samples contained detectable residues and Chlorpyrifos and cypermethrin were the most detected pesticides, while amounts of propargite, methamidofos, cypermethrin, chlorpyrifos were the largest detected and mounted to 0.99, 0.15, 0.015, 0.012 mg/kg respectively as a median values. Residues of methamidofos in only 2 samples were above the European MRLs.,
