| Abstract | ||||
| A total of 530 samples of different types of the fruits and vegetables collected from nine Egyptian local markets located in nine governorates throughout 2008. All samples were examined for residues of 80 pesticides. Overall, results showed that 84.5% of the samples had no detectable pesticide residues, however, 15.5% contained detectable residues, of which 4.5% contained residues that exceeded maximum residue limits (MRLs). Apricot, banana, green celery, lettuce, samples were free from pesticide residues. The fruits samples recorded the highest contamination percentage without exceeding of the levels of MRL’ (i.e. 20.8%), followed by vegetables (i.e.8.7%), and the leafy vegetables had the lowest percentage (i.e. 6.3%). Also, data showed that the leafy vegetables recorded the highest violation % (i.e. 7.2%), followed by fruits (i.e. 4.2%), and vegetables (i.e. 3.7%). The violated samples were guava, strawberry, orange, carrot, cauliflower, cucumber, eggplant, G. beans, G. peas, pepper, potatoes, tomatoes, watercress, G. coriander, and G. parsley. The violated compounds were cypermethrin, chlorpyrifos, diazinon, fenhexamide, profenofos, fenhaxamid , ethion, and chlorfenapyr .The highest frequently detected pesticide was profenofos, followed by lambada-cyhalothrin, fenhexamid , cypermethrin , ethion, chlorpyrifos , fenpropathrin , diazinon and imiazalil , carbendazin, dimethoate, and procymidone. However, the lowest frequently detected pesticides, which detected only one time, were boscalid, chlorfenapyr, flusilazole, iprodione, metalaxyl, pirimiphos, and pyraclostrobin. The results showed that 2.08% of all samples analyzed, contained residues of 9 pesticides, 1.13% contained residues of 8 pesticides, 0.94% contained residues of 6 pesticides, 2.26% contained residues of 5 pesticides, 0.38% contained residues of 4 pesticides, 3.21% contained residues of 3 pesticides, 3.4% contained residues of 2 pesticides, and 2.08% contained residues of 1 pesticide. The dietary exposures of the most frequently detected pesticides were theoretically calculated to evaluate the risk for Egyptian consumer. As shown by the results, the intake of pesticide residues does not exceed the ADI in any case. It is found to be below 10% of the ADI for all pesticides. The estimated exposure ranges from 0.00018% of the ADI for the malathion on each of molokia and spinach to 4.9% of the ADI for the ethion on tomato. | ||||
