Abstract

More and more researches are devoted to nanoparticles (NP) of metals and the discovery of the mechanisms of their influence on aquatic plants, since many NPs tend to show more toxicity in the water phase. In our study, we used an aquatic plant of Lemna minor L. The introduction of NP CeO₂ (1, 10 and 100 mg/l) from 7 to 30 days in the aqueous medium promoted a slight inhibition of the growth of the Lemon relative to control. Analysis of reductase activity with the tetrazolium salt showed that 10 and 100 mg/l of NP CeO₂ proved to be the most toxic, causing a decrease in the yield of formazan after 14 days of exposure by 27% and after 30 days by 31% compared to the control, respectively. The current study confirmed that nano-CeO₂ does not lead to significant metabolic changes and toxic effects in the aquatic environment against duckweed plants.
