Abstract
The toxicity effects of nano-ZnO suspension on antioxidant enzyme system of zebrafish embryos were investigated for evaluating its potential ecotoxicity. Exposure to nano-ZnO suspension led to the decrease in glutathione (GSH) content, the inhibition in catalase (CAT) and superoxidase dismutase (SOD) activity, and the increase in MDA level of zebrafish embryo.The result demonstrates that oxidative stress was one of the mechanisms of nano-ZnO ecotoxicity.
