Effect of Benzophenone-3 to Acetylcholinesterase and Antioxidant System in Zebrafish (Danio Rerio) Embryos 

Abstract Benzophenone-3 (BP-3) is one of the most used UV filters. This study aimed to evaluate the toxic effects of BP-3 during embryo stages of zebrafish, four hours post-fertilization (4hpf). Embryos were exposed to 0, 1, and 10 µg L-1 of BP-3, for 72 hours. We investigated biochemical and molecular biomarkers of neurotoxicity (AChE) and the antioxidant system (gene expression of catalase, CAT, superoxide dismutase, SOD, glutathione peroxidase, GPX, the concentration of total glutathione, GSH, and lipid hydroperoxides, LPO). Results indicated that the acute exposure to BP-3 in zebrafish embryos did not show significant differences in survival, hatching rate, or in the biomarkers of antioxidant system. In contrast, there were significant differences associated with AChE gene expression and activity.
