为评价纳米ZaO的水生态毒性,以斑马鱼胚胎为受试生物,研究了纳米ZnO对其抗氧化酶系统的影响.结果发现,纳米ZnO能够降低斑马鱼胚胎谷胱甘肽(GSH)含量,抑制过氧化氢酶(CAT)和超氧化物歧化酶(SOD)活性,引起胚胎脂质过氧化水平增大,证明氧化应激是纳米ZnO抑制斑马鱼胚胎孵化的作用机制之一.

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.
