Abstract

The presence of degradation products of bromopropylate, trichlorphon, parathion-methyl and tebuconazole in white and red wines elaborated from musts spiked with commercial formulations of the pesticides was studied. Must and wine were subjected to solid-phase extraction followed by gas chromatography with electron ionization mass spectrometric detection. Alpha-bromophenylphenylmethanol, aminoparathion, acetylaminoparathion-oxon and dichlorvos have been identified as degradation products of bromopropylate, parathion-methyl and trichlorphon in wines, respectively. Moreover, the presence of additives and impurities of the formulations in elaborated wines has also been found.
