title: Identification of metabolites of malathion in plant, water and soil by GC-MS.
abstract: Metabolism of malathion (O,O,-dimethyl S-[1,2-bis(ethoxy carbonyl)-ethyl]phosphorodithioate) has been studied in plants, water and soil. A number of products identified by gas chromatography-mass spectrometry (GC-MS), have been formed by de-esterification, oxidation and hydrolysis of malathion. Hydrolysis of the P-S and C-S bonds occur in alkaline pH 8.0 and acidic pH 5.5, respectively.
