Investigation of Changes in Malondialdehyde Level, Superoxide Dismutase and Catalase Activity in Liver Tissue of Capoeta umbla exposed to 2,4-Dichlorophenoxyacetic Acid

In this study, changes in malondialdehyde level (MDA), superoxide dismutase (SOD) and catalase (CAT) activity fish liver tissue were investigated by applying two doses of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide to Capoeta umbla for 72 hours. Changes MDA level, CAT SOD determined spectrophotometric methods. As a result the it was that there statistically significant increase C. exposed different (p < 0.05). It observed 2,4-D disrupted oxidant/antioxidant balance tissue. However, these antioxidant enzymes, which are primary defense mechanism, appear be resistant toxic effect 2,4-D.
