The impact of selected platinum group elements on antioxidant activity of duckweed (Lemna minor)
Original language description
An actual problem in the environmental burden begins to be platinum group elements (PGEs), which come from automobile traffic. Increasing use of PGEs in exhaust catalysts and the runoff from surroundings of busy highways, lead to increased spread and accumulation of these metals in water ecosystem. To determine how these metals may affect the antioxidant activity of aquatic plants we chose duckweed (Lemna minor L.) as a bioindicator. In this experiment we used spectrophotometric methods for determination of the antioxidant activity. Plants were exposed by the solutions of SIS and selected metals from PGEs: platinum (PtCl4) and rhodium (RhCl3). Lemna minor was cultivated in various concentrations of platinum and rhodium (1, 10 and 100 mýmol.l-1), respectively. The experiment lasted for seven days and sampling days were 2nd, 4th and 6th day. We chose two methods for this determination - FRAP and ABTS radical method. The influence of selected PGEs on Lemna minor was observed as a change o
