Abstract
Copper is one of the key heavy metals that pollute environment and constitute a serious threat to the
health of humans and ecosystems. Copper may enter the aquatic environment in both soluble and nanoparticle
form. It was previously found in a series of studies that nanoparticles, including those of several metal oxides,
exercise both negative and positive effects on the higher plants which makes necessary further research on the
interaction between metal oxide nanoparticles and plants. Interactions between aquatic plants and copper–containing
nanoparticles were not suffi ciently studied. The goal of this study was to contribute to the investigation of the
interactions between CuO nanoparticles and the aquatic plant Elodea canadensis under the conditions of experimental
microcosms. It was found that CuO nanoparticles demonstrated some phytotoxicity to Elodea canadensis.
After the incubation of Elodea canadensis in the aquatic medium contaminated with CuO nanoparticles there was
a signifi cant increase (by two orders of magnitude) of the concentration of copper in the biomass of the plants.
