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.

INTRODUCTION
Copper is one of the key heavy metals that pollute
the environment and constitute a serious threat to the
health of humans and ecosystems [1–3]. Copper may
enter the aquatic environment in both soluble and nanoparticle
form.
It was found in a series of studies that nanoparticles
including those of several metal oxides, exercise both
negative and positive effects on higher plants [4–7]
which makes necessary further research on the interactions
between metal oxide nanoparticles (NP) and
plants. Binding of several types of NPs to terrestrial
plants has already been found [5]. By contrast, no binding
of Fe oxide NPs to some species of higher plants
(Phaseolus limensis) has been detected [8].
Studies of interaction of pollutants with aquatic
plants are of signifi cant importance to both fundamental
ecology and applications [9–11]. The applications
include environmental monitoring and remediation of
polluted freshwater ecosystems. Among various types
of aquatic pollution, metal pollution is one of the most
important [12–17], which makes it urgent to continue
very active studies of various forms of metal aquatic
pollution (including pollution from NPs that contain
heavy metals) and its interaction with freshwater macrophytes.
Interactions between freshwater plants and copper–
containing NPs have not been studied suffi ciently. The
goal of this study was to contribute to the investigation
of the interactions between CuO NPs and the aquatic
plant Elodea canadensis (below E. canadensis) under
conditions of experimental microcosms.
