Isolation and determination of chlorinated organic pesticides by thin-layer chromatography and the application to toxicological analysis. 1977

S N Tewari, and I C Sharma

A sensitive method for the isolation and clean-up of chlorinated organic pesticides from tissues and biological materials is discussed. RF values of the pesticides in 26 solvent systems, and colours of the spots given with various chromogenic reagents, are reported. The limits of detection, and densitometric measurements, are also discussed. The average recovery has been found to be 94%. The distribution of endrin in different autopsy tissues from five different victims has been studied by the proposed technique.
