摘要：
With the rapid development and versatile applications of nanotechnology, a large quantity of nanoparticles (NPs) has been released into the environment. It has been one of the most popular studies that concerning the toxic effect of NPs to the algae in aquatic ecosystem. The membrane integrity of algal cells was assessed using different methods when algae were treated by CuO NPs in the absence and presence of Suwannee river fulvic acid (SRFA), one of DOM. We found SRFA could increase the toxicity of CuO NPs to cell membrane due to the more stable NPs suspension in the presence of SRFA. Results additionally indicate that maybe oxidative damage caused by CuO NPs was the primary reason that led to membrane structure and function failed.
