Abstract

Cytotoxic threshold dose of three commonly used pesticides (Malathion, Metacid and Lindane) was determined using relative division and abnormality rates in meristematic cells of Allium cepa root tip by using dose-dependent curves populated with varied number of smaller doses. The results obtained show such dose to be 25, 20 and 50 ppm for Malathion, Metacid and Lindane respectively.
