✦ Synopsis

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.

Photoproducts resulting from illumination of a pyrene-chloroform solution using several light sources (sunlight, lamp, a pulsed laser) were analyzed by using gas chromatography (GC) and GC-mass spectrometry. The main photoproducts in chloroform were chloropyrene and pyrenecarboxaldehydes, and their
