Аннотация: Broad application of CuO nanoparticles (CuO-NP) for industrial and household purposesleads to a continuous increase in their discharge to, and, hence, ever-increasing environmental hazards for aquatic ecosystems. Microalgae-based technologies hold promise for bioremediation of diverse hazardous micropollutants (HMP), including NP, from wastewater. In this study, we testedthe ability of the green microalga Desmodesmus sp. to accumulate CuO-NP or their components. Wealso assessed the tolerance of this microalga to the environmentally relevant concentrations of CuONP. Using scanning electron microscopy, we demonstrated that the average size of CuO-NP was50–100 nm, and their purity was confirmed with elemental composition analysis. Tests of the colloidal suspensions of CuO-NP showed that the hydrodynamic diameter of CuO-NP and their aggregates was below 100 nm. Flow cytometry analysis showed that CuO-NP at a concentration of100 µg L−1 slightly inhibited the viability of microalgae cells and led to an increase in their oxidativestress. The assessment of the condition of photosystem II showed that CuO-NP exert a multifacetedeffect on the photosynthetic apparatus of Desmodesmus sp., depending on the concentration of andthe exposure to the CuO-NP. Desmodesmus sp. turned to be relatively tolerant to CuO-NP. In addition, the ICP-MS method revealed increased bioaccumulation of copper by microalgae cells in theexperimental groups. The outcomes of this study indicate that the Desmodesmus sp. has a significantpotential for bioremoval of the copper-based nanostructured HMP from an aquatic environment.
