Risk assessment of dietary exposure to chlorpyrifos residues on some fruits, vegetables and herbs in Egypt during 2002.
Abstract: The central laboratory for pesticide residue analysis and heavy metals in food have been set up by the Egyptian Ministry of Agriculture and finland conducts tests to evaluate the save usage of pesticides in Egypt. Chlorpyrifos is one of the most widely applied organophosphate insecticide, It is classified as a general use pesticide (GUP) and it is registered for agriculture uses with 64 crop in the Egypt. A total of 12919 samples of 57 different types of fruit vegetable and aromatic medicinal plants samples were examined for chlorpyrifos residues during 2002. It was found that fifteen commodities represent total 12193 samples of fruits (2634), vegetables (2494) and aromatic medicinal plants (7065) with percentage 94.38 % of total examined samples have chlorpyrifos residues (contaminated commodities). Only 10.16 % of the total contaminated commodities (12193 samples) were below limit of determination (LOD = 0.02 ppm), 9.62 % at LOD or more however 80.21 % of those samples are not contaminated with chlorpyrifos residues. Only 6.33 % of the samples exceeded MRL's of chlorpyrifos residues comparing with national, Codex And EU-MRL's. chlorpyrifos residue were the detected frequently in dry celery and cumin samples with percentages of 61.54 % and 40.91 % respectively and also showed higher violation rate for the same commodities 58.97 % and 40.91 %. The major contributors to total intake of chlorpyrifos residue is the root vegetables (81.89 %). Data showed that the total dietary intake of chlorpyrifos is to be 0.0045 mg/kg. body weight / day is lower than ADI (0.01 mg/kg body weight) and contributing only 45 % of ADI. Therefore dietary exposures to chlorpyrifos are still not a case for Egyptian consumer concern.
