| Abstract: | The effects of terbutryn at concentrations of 0.02 (reported concentration in Czech rivers), 0.2, and 2.0 μg l?1 were assessed in one-year-old common carp (Cyprinus carpio L.) exposed for 90 days. Influence on biometric parameters, hematology, biochemistry, histology, and oxidative stress was investigated. Exposure to 0.02, 0.2 and 2.0 μg l?1 showed significant differences oxidative stress biomarkers compared to controls but exposure to 0.2 and 2.0 μg l?1 significantly affected biochemical and hematological profiles. Long-term exposure of terbutryn in carp resulted in slight alterations in internal organs and increased reactive oxygen species formation, resulting in oxidative damage to lipids and proteins and inhibition of antioxidant capacities. |
