Characterization of fluvalinate residues in honey by gas chromatography–atomic emission detection and gas chromatography–mass spectrometry

Abstract

AbstractTwo hyphenated techniques, gas chromatography–mass spectrometry and gas chromatography–atomic emission detection, have been used to identify the degradation products of the acaricide fluvalinate in a methanol solution of the commercially available formulation Mavrick, as well as in honey from beehives treated with this product. The major degradation products were 2‐chloro‐4‐trifluoromethylaniline (I), methyl 2‐[2‐chloro‐4‐trifluoromethylaniline]‐3‐methylbutanoate (II), N‐(2‐chloro‐4‐trifluoromethyl‐phenyl)valine (III), and 3‐phenoxybenzaldehyde (IV). Fluvalinate in honey is gradually degraded, 3‐phenoxybenzaldehyde being the most abundant residue.
