  The appearance of pesticides in agricultural products is a serious concern for consumers. The purpose of this study was to evaluate the amount of pesticides in cucumber in Fars province. The process of work was that 64 samples of fresh cucumber were analyzed for the presence of 4 pesticides (diazinon, imidacloprid, primicarb and acetamiprid) using the quick, easy, cheap, effective, rugged and safe (QuEChERS) multi-residue extraction, followed by high performance liquid Chromatography-Diode array detector (HPLC-DAD). The residual behavior of diazinon (60%EC), primicarb (50% WP) imidacloprid (35% SC) and acetamiprid (20% SP) in cucumber under the greenhouse condition was studied. The cucumbers were randomly sampled after 2 (initial), 5, 10 and 14 days period after pesticides application. Both of acetamiprid and primicarb were found to be more persistent in cucumber compared with the other two tested pesticides; data also reported that the lowest residue (level 2.06 and 2.12 mg.kg-1)in cucumber was detected 14 days after application of acetamiprid and primicarb, while the lowest residue of diazinon and imidacloprid was 0.24 and 1.16 mg.kg-1 within 14 days. All tested residues dissipated 21 days after application in cucumber. Manuscript profile

  In this research to investigate the probable contamination of the apple tree to pesticides that is used by farmers in Miandoab, the residues of Diazinon and Chlorpirifos were investigated in this crop. First, the sampling is carried out by using the simple random sampling method and then, after Solid Phase Extraction (SPE) through High-Performance Liquid Chromatography (HPLC), the residues of Diazinon and chlorpirifos were measured. So that, the pesticides residues in apples that were washed with skin, without skin and, in peeled apples were measured 0.08, 0.31, 0.68 ppm for Diazinon and 0.24, 0.54, 0.98 ppm for Chlorpirifos, respectively. Comparison of the statistical results with global standards reveals that the residues of Diazinon in Apples with the skin, and the residues of Chlorpirifos in three modes: Unwashed with the skin, washed with the skin and peeled is more than global standards (Diazinon 0.5 ppm and Chlorpirifos 0.01 ppm) Therefore, it is required that the authorities and farmers of this region pay special attention to residues and the time of applying pesticides; thereby, they can prevent endangering health society.
