Abstract

CuO nanoparticles (NPs) are widely used in commercial applications. With increasing CuO NPs production, CuO NPs are likely to present in the environment and pose a potential threaten to ecosystem. In this work, 20 and 50 mg/L CuO NPs and 0.15 mg/L Cu2+ were used to test the toxicity to Arabidopsis thaliana roots. Results showed that CuO NPs can inhibit the root dry weight and root water content at 96 h. ROS and MDA content were increased after exposure to CuO NPs for 96 h. Cu2+ released from CuO NPs exhibited no toxicity on the Arabidopsis thaliana roots.
