Environmental significance Zinc oxide nanoparticles (ZnO NPs) undergo transformations in wastewater treatment plants and water environments, resulting in changes in physicochemical properties. Thus, to accurately evaluate the ecological toxicity of ZnO NPs, the effects of transformations and underlying mechanisms of toxicity must be considered.
