DETECTION OF PESTICIDES IN VISCERA SAMPLES BY THIN LAYER CHROMATOGRAPHY

Shailesh Kumar Rai, Ramkrishna Mishra, Manoj Kumar Pathak

Abstract :

Pesticides of various categories viz. organophosphates, organochlorines and carbamates are used as suicidal and homicidal poisons across the country. They are isolated from postmortem viscera samples by direct extraction and steam distillation. The detection and identification of 11 pesticide residues from 70 postmortem viscera samples was done by thin layer chromatography using different solvent systems and spraying by appropriate chromogenic reagents. Malathion, Methyl Parathion and Phorate were detected in maximum samples indicating their extensive use as suicidal and homicidal poison by people of eastern Uttar Pradesh.
