Plasma and RBCs antioxidant status in occupational male pesticide sprayers

A total of forty-one (n=41) male, healthy agricultural sprayers, exposed to pesticides for 5 years, were compared with twenty one (n=21) controls matched for age and economic status with respect to free radical generation, lipid peroxidation, antioxidant status and concentration of cellular enzymes were determined. Significantly increased TBARS (thiobarbituric acid reactive substances) were observed (P<0.001) in sprayer populations when compared to controls. The concentration of antioxidants such as glutathione (GSH), alpha-tocopherol, ascorbic acid and ceruloplasmin were significantly altered when compared to controls, and the activities of antioxidant enzymes were remarkably elevated (P<0.001) in sprayer populations, when compared to controls.
