Abstract

In the present investigation dimethoate and phosphamidon pesticides presents on soil and paper material have been examined using Thin Layer Chromatography. Among the fifteen different solvent systems examined, it has been observed that dimethoate can be separated by using Benzene: Acetone (9 : 1) and phosphamidon by using cyclohexane . Acetone' chloroform (70 : 25 : 5) followed by iodine fuming as visualizing aid. The analysis of these two compounds could be successfully performed even up to 8 weeks times from soil and paper containing these pesticides in small amounts and it remains therein. The study will provide a useful information to the forensic toxicologists.
