A method for the determination of chlordanes (total of 19 compounds: heptachlor, compound C, compound K, α-chlordene, β-chlordene, γ-chlordene, traps-chlordane, cis-chlordane, trans-nonachlor, cis-nonachlor, oxychlordane, heptachlor epoxide, compounds 1, 2, 3, 5, 6, 7 and 8) by mass spectrometry with selected ion monitoring (SIM) was developed. Chlordanes were extracted from samples with organic solvents (e. g. hexane-acetone), partitioned with hexane-acetonitrile, cleaned-up by Florisil column chromatography with a hexane-dichloromethane-ethyl ether solvent system, and determined by SIM. The determination of chlordanes by SIM was carrided out under the following conditions: 1% OV-210+1% OV-275 and 2% OV-210 columns; column temperature, 175-220°C; He, 40ml/min; mainly M-Cl ions; ionization voltage of 27 or 30eV. Recoveries of chlordanes added to samples (water, fish and shellfish, beef and cow's milk) were in the range of 76-102%.
