[Rapid gas chromatographic method of determining organochlorine insecticides in human fatty tissue]

A prompt, readily executed method for chlororganic insecticides determination in human fatty tissue is developed. The analytical course includes sample extraction with hexane, liquid distributional extraction with acetonitrile, and purification through small aluminium dioxide column. Final determination is performed with gas-liquid chromatography using electron detector. The method is endowed with a very high sensibility ranging from 0.1 micron/kg for hexachlorcyclohexane to 0.8 micron/kg for methoxychlor. Attained is a mean analytical yield for heptachlorepoxide amounting to 94 per cent. Reproducibility is fully satisfactory at interval of dispersion of the single measurement 9 per cent; confidential interval of the mean - 3 per cent. The method is successfully applied in mass investigations of the general population for level of chlororganic insecticides' determination.
