✦ Synopsis

A simple analytical method for determining Fluvalinate residues in honey is described. Analyses were carried out by gas chromatographyÈelectron capture detector (ECD), using a borosilicate glass column packed with 3% SP-2100. Fluvalinate residues were extracted from honey samples with n-hexane and acetic acid. Mean recoveries ranged from 98É1 ^6É9 to 101É9^7É6% with SD \ 10 after standard addition of 20, 50 and 500 lg. No interferences of other pesticides were detected. ECD responses were linear within the range studied of 10È50 pg of Fluvalinate with a coefficient of determination 0É994, and a detection limit of 3 mg kg~1 was established. The use of a packed column allowed the exclusion of an expensive clean-up step. This fast, low-cost analytical method is adequate for monitoring studies of honey samples.
