Abstract
The application of a simultaneous water steam distillation-organic solvent extraction (SDE) method for the GC-electron-capture detection of hexachlorobenzene, α-hexachlorocyclohexane (α-HCH), γ-HCH, cis-heptachlorepoxide, 2,4′-DDE, 4,4′-DDE, dieldrin, 2,4′-DDT and 4,4′DDT in milk powder and other milk products is described. The SDE apparatus was a newly designed modification of the apparatus of Likens and Nickerson and Godefroot and co-workers and light petroleum was used as the extraction solvent. The method extracted the organochlorine pesticides selectively and with high recovery from interfering matrix compounds. Extraction and clean-up were performed in one step, followed by a simple concentration step. Quantification was performed using pentachlorobenzene and Mirex as internal standards. The limit of determination was between 0.5 and 2 ng/g, depending on the analyte.
