Erythrocytes are excellent models for the study of interactions of xenobiotics with biomembranes. Present work is designed to study the in vitro effects of some organophosphates (ethion, chlorpyrifos, dimethoate and monocrotophos) on rat erythrocytes. Treatment of erythrocytes with organophosphates resulted in decreased erythrocyte glucose-6-phosphate dehydrogenase (G-6-PD) activity, whereas ac...

Farmed and wild samples of two weight Cirrhinus viz., 501-900 g and 901-1300 g of Cirrhinus mrigala were collected from a Commercial Fish Farm and from river Chenab at Trimu Head Jhang, respectively. The extracted residues were pesticides analyzed through reverse phase high performance liquid chromatography (HPLC) technique. Endosulfan α, p, p’-DDT, methamidophos, carbofuran, diazinon, parathio...

A simple and rapid method is described for the estimation of some organophosphorus insecticides in the serum of occupationally exposed persons. The compounds are extracted with a mixture of acetone and diethyl ether (1:1 v/v) in acidic medium and the extraction residue is analyzed by gas chromatography with nitrogen phosphorus detection method. Linearity was acceptable over concentrations from ...
