Determination of Pesticide Residues in Some Vegetable Species by LC-MS/MS and GC-MS

In this research, 203 different pesticides’ residue levels were investigated in tomatoes, pepers and eggplants vegetable samples which taken from local markets and wholesale markets in Konya City. Vegetable sample extractions were performed in Selcuk University Agricultural Faculty laboratories of both departments of Horticulture and Crop sciences, while LC-MS/MS and GC-MS analysis were conducted in the Organic Agricultural Products and Residue Analysis Laboratory of Republic of Turkey Ministry of Agriculture and Rural Affairs Izmir Province Control Laboratory. According to conducted results, Oxamyl which is completely prohibited was found in a sample of tomato that this value exceeds about 7 times the limit value given (10.0 μg/kg) in Turkish Food Codex; two different pesticides was found in a sample of pepper (112.0 μg/kg Ethion ve 75.0 μg/kg Triazophos); Benomyl-carbendazim (TFC tolerance value 100.0 μg/kg) was found to be 120.0 μg/kg in another sample of pepper. Ten eggplant samples which are taken to the experiment, Oxamyl which is completely prohibited, was determined as 107.0 μg/kg in a sample of eggplant that this value exceeds about 11 times the limit value. Hovewer, imidiacloprid (TFC tolerance value 20.0 μg/kg) values were found to be 49.0, 190.0 ve 64.0 μg/kg in three eggplant samples respectively.
