title: [The detection of beta-cypermethrin during forensic chemical expertise of biological materials].
abstract: The optimal conditions for the isolation of beta-cypermethrin from biological materials by means of dioxane extraction have been developed. The possibility to purify beta-cypermethrin from endogenous impurities is demonstrated by combination of liquid-liquid extraction and chromatography through a silica gel column (L 40/100 mcm). It is shown that identification and quantitative determination of beta-cypermethrin extracted from the cadaveric liver tissues are possible using such techniques as thin-layer chromatography, electron spectrometry, and chromato-mass spectrometry. A method for forensic chemical expertise of the presence of beta-cypermethrin in biological materials is described.
