  Unequivocal Identification of Compounds Formed in the Photodegradation of Fenitrothion in Water/Methanol and Proposal of Selected Transformation Pathways

  摘要：

  The photodegradation of fenitrothion was examined in a mixture of distilled water/methanol (5:1), The UV irradiation was carried out with a high-pressure Hg lamp during 7 h. For the identification of further breakdown products, fenitrooxon and carboxyfenitrothion were also irradiated under experimental conditions identical to those for fenitrothion. The identification of the breakdown products formed was carried out by gas chromatography-mass spectrometry (GC-MS) with electron impact (EI) and comparison with authentic standards synthesized in the laboratory. A total of 21 photoproducts of oxidation, isomerization, denitration, and solvolysis that may be of concern in environmental studies were unequivocally identified. Among them were formyldenitrofenitrothion, carbomethoxydenitro-fenitrooxon, and hydroxymethyldenitrofenitrooxon. A proposed mechanism of the process is presented. Selected pathways for the photodegradation of fenitrothion were examined: (i) degradation through hydrolysis, with eventual remethylation; (ii) P=S to P=O oxidation; (iii) denitration; and (iv) oxidation of the methyl substituent through hydroxymethyl and formyl to give the corresponding carboxy derivatives.

  ultraviolet light was investigated, Its stability to sunlight on leaf surfaces of bean plants and on different surfaces (such as glass, quartz and plastic) was also determined. The main photoproducts were identified as carboxyfenitrothion, fenitrooxon, carboxyfenitrooxon and 3-methyl-4-nitrophenol and a small amount 3-caboxy-4-nitrophenol and methyl parathion. The addition of carbaryl and deltamethrin
