| Abstract: | A simple analytical method for determining Fluvalinate residues in honey is described. Analyses were carried out by gas chromatography–electron 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 98·1±6·9 to 101·9±7·6% with SD<10 after standard addition of 20, 50 and 500 μg. No interferences of other pesticides were detected. ECD responses were linear within the range studied of 10–50 pg of Fluvalinate with a coefficient of determination 0·994, 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. © 1998 SCI. |
