Abstract | ||
Persistence of chlorpyrifos-methyl organophosphorous insecticide residues on cucumber fruits was studied. The effect of washing, peeling and pickling on chlorpyrifos-methyl residues were also studied. The residue half-life value of chlorpyrifos-methyl on cucumber fruits was 17 hours. The residues reached a safe level below the MRL three days after treatment. All the previously mentioned processing steps caused a significant reduction in the insecticide residues. Another part of this study was a survey carried out for detection of organophosphorous insecticide residues on cucumber fruits in some local markets (i.e. Benha, Kaha, El-Mansoura, Belkas, El-Mahalla). The results indicate that all detected organophosphorous residues were below the MRLs of Codex. | ||
