Determination of organochlorine pesticide residues in honey, applying solid phase extraction with RP-C18 material

In this study, a new clean up method was developed for the routine multires idue determination of organochlorine pesticide residues in honey. The analy tical procedure requires sample extraction with methanol, followed by a cle an up step through a C18 Sep-Pak cartridge. Finally, pesticides are eluted with hexane. The determination of organochlorine pesticide residues was per formed by capillary gas chromatography with electron capture detection. The mean recoveries of 18 organochlorine pesticides were estimated at various concentrations and found very efficient in most cases. The detection limits were found to be between 0.05 and 0.20 mu g kg(-1).
