Abstract

A total 45 fish samples(Tilapia , Claris )were collected from EL-Bagoria, EL-Menofi drainage and Bahr Shibin for detection and determination of organophosphorus pesticides (diazinon, Malathion and chlorpyrifos).

Organophosphorus  pesticides could not be detected in Bahr Shibin No diazinon in Tilapia from EL-Bagoria but mean value of of Malathion 5.50±2.0, chlorpyrifos 5.0±1.66but  from EL-Menofi drainage mean level of diazinon 3.33±0.65, Malathion 4.98±1.22 and chlorpyrifos3.0±0.71but in Claris samples , there were no diazinon, no Malathion, no chlorpyrifos from EL-Bagoria canal but from EL-Menofi drainage, mean value of diazinon 6.8±1.42, Malathion 4.64±0.81 and chlorpyrifos4.0±0.96.

Pesticides  are one the main contaminant of water sources which are considered the natural environment of fish . on the other hand , fish could be contaminated by pesticides either directly by gills breathing or indirectly through contamination of feeding items so it is very important to analyze  fish samples to detect to what extent the rate of accumulation of pesticides residues in fish flesh and organs.
