The contact between metal oxide nanoparticles (NPs) and human is more and more close with their wide applications. The inputs of metal oxide NPs to the environment are also growing every year, which causes potential environmental and human health risks. They are toxic to animals, microorganisms and plants at high concentrations, and they show different mechanisms of toxicity to different species. In addition, under complex environmental conditions, their toxic effects are often unpredictable. We have integrated the recent studies on the biotoxicity of metal oxide NPs from 2015-present, and clarified their toxic mechanism, as well as the toxic harm. It lays a foundation for further studying the toxicity and ecological risk of metal oxide NPs.
金属氧化物纳米粒子（NPs）的广泛应用使得其与人类的接触越来越紧密。与此同时，金属氧化物 NPs 每年也在以越来越多的形式输入到环境中，这给环境和人类健康带来了潜在风险。在高浓度下，它们对动物、微生物和植物都具有毒性，并且对不同物种表现出不同的毒性机制。此外，在复杂的环境条件下，它们的毒性作用往往是不可预测的。我们综合了 2015 年至今有关金属氧化物 NPs 生物毒性的最新研究，阐明了它们的毒性机制和毒性危害，为进一步研究金属氧化物 NPs 的毒性和生态风险奠定了基础。
