Abstract

The ser_l_OUS deficiencv in agricultural products that faces
most developing countries, made it invitable to use pesticides
in controlling different pests that cause great loss in these
products. However, it was proved that several pesticides were
dangerous pollutunts to humans and their environment. As a
matter of fact, most developing countries are consumers and
not producers of these toxicants. Therefore, they must have
their own measures of safety before permitting the introduction
of any pesticide. In other words, they must have their own
protocols to develop their National data base.
In the last two decades, several investigations indicated the high
correlation between the genotoxicity of chemicals and
their carcinogenic and teratogenic activities. The idea of
considering some simple and unexpensive test as short term assays
for evaluating the risk of exposure to such chemicals are generally
accepted now. Multistep International Programmes for
Chemical Safety are arranged to determine the best battery
system and the ideal protocols for conducting genotoxicity
tests, Brusik ( 1980).
In Egypt, several trials were carried out to study the
genetic activities of widely used pesticides. However, these
results were not taken in consideration in the evaluation of
