Evaluation of methyl parathion residues in apple samples obtained from different regions of Turkey [Torkiyenin farkli bolgelerinden saglanan elma orneklerinde metil paratiyon kalintilarinin degerlendirmesi]

In this study, the levels of methyl parathion (MP) residue in apples collected by Market-Basket method were evaluated. A multiresidual analysis method recommended by AOAC for organophosphorus insecticides has been applied for MP analysis. A Hewlett-Packard 5890-II gas-chromatograph equipped with nitrogen-phosphor detector and SE-30 column was used. MP residues in 18 samples were found at levels below the maximum residue limits registered both in Turkey (0.1 ppm) and by Codex Alimentarius Commission (0.2 ppm) while no detectable levels were found in the rest
