| Description
| - Road traffic pollutants and the residues of cytostatics that are widely used in anti-cancer therapy are a significant sources of platinum group elements (PGE; Pt, Pd and Rh) in environment. These metals can migrate into sewage and thus pollute surface waters. The purpose of our study was to evaluate the effect of PtCl4 on the antioxidant and enzymatic activity of duckweed (Lemna minor), a bioindicator of the aquatic environment. The study was performed using a 7-day conventional test based on the OECD 221 (CSN EN ISO 20079) - Lemna sp. Growth Inhibition Test. We also conducted a microbiotest to analyse the effects of PtCl4, PdCl2 and RhCl3 on the morphology and vegetative growth of colonies of this plant and compared their inhibitory effects during the microbiotest. We observed inhibition of colony growth and clear morphological changes. Antioxidant and enzymatic activities increased with platinum doses increased. The 168hEC50 of PtCl4 was 12.16 mýM (95% confidence interval = 9.88-14.44) and the 168hEC50 of PdCl2 was 50.39 mýM (95% confidence interval = 23.83-76.96). The greatest inhibition of growth by RhCl3 was observed at 25 mýM. The obtained results suggest that L. minor phytotoxicity tests should be widely used in the biomonitoring.
