Keywords CuO nanoparticles Spirodela polyrrhiza Toxicity Antioxidant enzymes Introduction Nanotechnology has been a great ﬁeld of discovery in recent decades . Nanomaterials are a diverse class of material in tiny scale, and nanoparticles are a subset of nanomaterials with 1–100 nm size in two dimensions . Nanomaterial surface characteristics such as surface area, surface charge, and surface reactivity are noted causes of nanoparticle toxicity . This toxicity has attracted the attention of researchers as they are generated in lofty amounts due to their use in biomedical, pharmaceutical, and industrial applications and their subsequent release into the environment . These nanoparticle surface features are important for their collective behavior that cause their motion in aquatic environment and for their interaction with aquatic organisms . Thus, it is important to know about the risks of nanoparticles in aquatic ecosystems as they effect on health of ecosystems . Among the types of nanoparticles, metal oxide nanoparticles are most commonly used and have many applications in cosmetics and sunscreen , gene therapy , electrospray disinfectants , textiles , and many other ﬁelds. In recent decades, several studies have reported the potential toxicity of metal oxide nanoparticles ; however, little investigation
