Oxidative stress response in Nile tilapia (Oreochromis niloticus) exposed to textile mill effluent.
Textile mill effluent is an important pollution factor because of its organic and inorganic substances content. In this study, toxic effects of textile mill effluent on fish Oreochromis niloticus were investigated by using antioxidant enzymes and lipid peroxidation (LPO) responses. Superoxide dismutase (SOD), catalase (CAT) enzyme activities and lipid peroxidation by means of thiobarbituric reactive substances (TBARS) level were measured in liver and gill tissues of fish. The fish were exposed to non-lethal concentrations (0.1%, 1% and 10%) of textile mill effluent for 15, 30 and 45 days. In control group, fish were left in aquariums containing tap water without chlorine. As a result, the activities of SOD, CAT enzymes and level of TBARS in the liver and gill increased in 15, 30 and 45 days after 1% and 10% doses application.
