Fluorescent nanoplastics increase the toxic effects of Graphene oxide nanoparticles in freshwater algae <i>Scenedesmus obliquus</i>.

ABSTRACT: The increased usage of Graphene oxide (GO) in various industrial applications led to their entry into freshwater systems. Other secondary contaminants like nanoplastics (NPs) often co-exist with GO in the environment. This study examines the possible role of fluorescent nanoplastics (FNPs) in modifying the toxic effects of GO on freshwater algae Scenedesmus obliquus. Selected concentrations of GO (0.1, 1, and 10 mg L^-1) were combined with a fixed concentration of FNPs (1 mg L^-1) to perform combinational toxicity tests on algae. FNPs significantly enhanced the toxic effects of GO in the mixtures in comparison with the pristine GO. In addition to the cytotoxic effects, oxidative stress parameters like total ROS generation and malondialdehyde (MDA) production also
