Abstract :

Considering the abundant application of pesticides, the subject of pesticides and their exceeded residues on harvested crops is important issue in agriculture. For this purpose, comprehensive and several studies on agricultural products should be done to prevent of entering of contaminated samples in using cycle. In this study, among 29 fruits and vegetable markets in Karaj, 10 of them in different parts of the city were considered, and 25 samples were randomly prepared for each specimen, weighing 2 kg. Samples in laboratory were extracted by using Solid Phase Extraction (SPE) and with the help of N method were concentrated and extracts were injected into High Performance Liquid Chromatograph (HPLC), Gas Chromatograph (GC/NPD), GC/Mass Spectrometer (GC/MS) devices for measuring the residue. Obtained data were compared with WHO/FAO and national Maximum Residue Limit (MRL) codex by T-test.The results showed that for chlorpyrifor 6 and 20 numbers (24 and 80%) of samples based on WHO/FAO and MRL codex respective, and for deltamethrin 14 numbers (56%) of samples based on WHO/FAO codex have had exceeded contamination of insectides.
