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. © 1997 John Wiley & Sons, Ltd.
