Dietary exposure assessment of chlorpyrifos methyl residue for some fruits, vegetables and herbs in Egypt during 2002
Abstract: The study of chlorpyrifos methyl was conducted in the central laboratory pesticide residues analysis and heavy metals in food have been set up by Egyptian Ministry of Agriculture and Finland conducts tests to evaluate the safe usage of pesticides in Egypt. Chlorpyrifos methyl one of the most widely applied organophosphate insecticide; It is classified as moderately acutely toxic by the oral route. A total of 12919 samples of 57 different types of fruits, vegetable, and aromatic medicinal plants samples were examined for chlorpyrifos methyl residues during 2002, thirty three commodities represent 36.44% were completely free of chlorpyrifos methyl residues. Twenty four commodities represent total 8211 vegetables (1592) and aromatic medicinal plants (6619) with percentages 63.56 % of total examined samples have chlorpyrifos methyl residues. All fruit samples were free from chlorpyrifos methyl residues. Only 1.57 % of total contaminated commodities (129 samples) were below limit of determination (LOD = 0.05 ppm ), 8.61 % at LOD or more However 91.39 % of those samples are not contaminated with chlorpyrifos methyl residues. Only 5.76 % of the samples exceeded MRL's of chlorpyrifos methyl residues comparing with national, codex and EU-MRL's. Chlorpyrifos methyl residues was the detected frequently in grapes leaf and cabbage samples with percentage of 2.9 % and 2.3 %, respectively also grapes leaf showed higher violation rate 1.45 % followed by dry molokhia 1.17 %, cabbage and water cress with percentages of 1.15 %. The contributors to total intake of chlorpyrifos methyl is the root vegetables 45.95 %. Data showed that the total dietary intake of chlorpyrifos methyl 0.00094 mg/kg. body weight/day is lower than ADI (0.01 mg/kg body weight) and contributing only 9.4 % of ADI. Therefore dietary exposures to chlorpyrifos methyl are still far and not a case for Egyptian consumer concern.
Key words: Chlorpyrifos methyl, Exposure assessment, Residue, Monitoring, Fruits and Vegetables, Herbs, Aromatic and medicinal plants.
