Metabolites of sulfur‐containing derivatives of the fungicides pentachloronitrobenzene and hexachlorobenzene in mammals, separated by capillary gas chromatography and identified by negative and positive Cl mass spectrometry

Biotransformation products of sulfur‐containing derivatives of pentachloronitro‐benzene and hexachlorobenzene in mammals, such as thiophenols, thioanisoles, phenols, anisoles and chlorinated benzenes have been identified by mass spectrometry of negative and positive ions produced by chemical ionisation. The capillary gas chromatograms of extracts from excreta of rats after application of N‐acetyl‐S‐(pentachlorophenyI)‐D,L‐cysteine, as well as of rabbits after application of S,S'‐(tetrachloro‐p‐phenylene)‐L,L'‐dicysteine, are shown.

Key words:

• Fungicide metabolism
• thiophenol
• cysteine derivative
