CHARACTERIZATION OF FLUVALINATE RESIDUES IN HONEY BY GAS-CHROMATOGRAPHY ATOMIC-EMISSION DETECTION AND GAS-CHROMATOGRAPHY MASS-SPECTROMETRY

Two hyphenated techniques, gas chromatography-mass spectrometry and ga s chromatography-atomic emission detection, have been used to identify the degradation products of the acaricide fluvalinate in a methanol s olution of the commercially available formulation Mavrick, as well as in honey from beehives treated with this product, The major degradatio n products were 2-chloro-4-trifluoromethylaniline (I), methyl chloro-4 -trifluoromethylaniline]-3-methylbutanoate (II), N-(2-chloro-4-trifluo romethylphenyl)valine (III), and 3-phenoxybenzaldehyde (IV). Fluvalina te in honey is gradually degraded, 3-phenoxybenzaldehyde being the mos t abundant residue.
