Abstract: | Two 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. |
