Abstract

Zinc oxide nanoparticles (ZnO NPs) and titanium dioxide nanoparticles (TiO₂ NPs) are well known as photoreactive nanoparticles (NPs). Various phototoxicities of ZnO NPs and TiO₂ NPs were reported on several organisms. It was still necessary to evaluate the toxicity of photoreactive ZnO NPs and TiO₂ NPs due to species-specific effects under various irradiation conditions. We compared the acute toxicity of Moina macrocopa under visible, ultraviolet (UV) A, and B irradiations, according to the Organization for Economic Cooperation and Development guidelines for the testing of chemicals (Test No. 202). The sensitivity of ZnO NPs for M. macrocopa was UVB>UVA>visible light irradiation. There were no significant lethal and immobile effects of TiO₂ NPs on juveniles under all irradiations and in the tested concentrations of TiO₂ NPs. Photoreactive NPs have a potential and accelerated toxicity on organisms in the ambient environments.

光反应纳米颗粒对大月牙蛾的加速生态毒性研究。

氧化锌纳米粒子(ZnO NPs)和二氧化钛纳米粒子(TiO2 NPs)是众所周知的光反应性纳米粒子(NPs)。报道了ZnO NPs和TiO2 NPs对几种生物的不同光毒性。在不同的辐照条件下，光反应性ZnO NPs和TiO2 NPs的毒性由于存在物种特异性效应，仍有必要进行评估。根据经济合作与发展组织化学品测试指南(测试号202)，我们比较了大红豆在可见光、紫外线(UV) A和B照射下的急性毒性。氧化锌NPs对巨藻的敏感性为UVB>UVA>可见光。在不同浓度的TiO2 NPs下，TiO2 NPs对幼鱼均无明显的致死性和不动性影响。光反应性NPs对环境中的生物具有潜在的和加速的毒性。
