  The present study was undertaken to evaluate the effects of cadmium chloride and commercial formulation of glyphosate (Roundup®) on oxidative stress biomarkers in the Nile tilapia, Oreochromis niloticus through three exposure periods with different concentrations of LC50. The 96h-LC50 were determined for CdCl2 (132 mg/l), glyphosate (9.63 mg/l), CdCl2 in mixture (41.30 mg/l) and glyphosate in mixture (2.75 mg/l), respectively. The fish was exposed to these concentrations separately and mixed for 4 days as well as two sublethal concentrations (1/4 and 1/10 LC50) for 8 days and 45 days, respectively. Gills and liver cells of the exposed fish were taken after 4, 8 and 45 days to investigate the variation in activity of lipid peroxidation malonaldehyde (MDA) and antioxidant enzymes of catalase (CAT), superoxide dismutas..
