Abstract EN
This study examines the potential hazard of an individual nanomaterial on the Cu biotoxicity to aquatic organisms.
Daphnia magna in the absence or presence of nano-TiO2 was exposed to Cu.
Maintaining nano-TiO2 at a safe concentration cannot eliminate its potential hazard.
The biomarkers superoxide dismutase, catalase, and Na+/K+-ATPase in D.
magna were measured.
Cu in the presence of nano-TiO2 induced higher levels of oxidative stress and physiological damage because of the sorption of Cu.
Nano-TiO2 also caused Na+/K+-ATPase inhibition possibly by impeding the Na+/K+ transfer channel.
The correlations among the biomarkers, mortality, and accumulation further showed that the overloading reactive oxygen species generation caused by nano-TiO2 contributed to deeper oxidative stress and physiological regulation, thereby causing greater toxic injury.
