摘要: Benzophenone (BP) type UV filters are widely used in many personal care products to protect human from irradiation. Despite the estrogenic potencies fish and environmental occurrences of BP derivatives aquatic systems, little information is available regarding their effects on antioxidant defense system fish. In this work, oxidative stress induced livers Carassius auratus was assessed using four biomarkers. The integrated biomarker response (IBR) applied assess overall status Moreover, liver tissues were also studied histologically. changes activities enzymes glutathione levels suggested that BPs generates IBR index revealed hepatic toxicity followed order BP-1>BP-2>BP-4>BP-3. histopathological analysis lesions caused by BPs. This investigation provides essential for assessing potential ecological risk BP-type filters.
