Abstract

This biodegradation study of alachlor in water was designed to assess the presence and the identity of metabolites. Alachlor was incubated in river water for 28 days. The pesticide and its transformation products were extracted by solid phase extraction and analyzed by gas chromatography/mass spectrometry. Selected samples were also analyzed by liquid chromatography/mass spectrometry. The disappearance of the pesticide was not significative, but several compounds were identified as alachlor metabolites. Nine compounds were confirmed by comparison with synthetic standards. One metabolite has never been reported. For seven molecules, formulae were presumed on the basis of spectrum interpretation and literature data.
