Abstract

The intensive use of engineered nanoparticles (NPs) in industrial, agricultural and household ap- plications will very likely lead to the release of such materials into the environment, especially water ecosystems. Water plantsare an integral part of ecosystems; hence their interaction with NPs is inevitable. It is important to understandthe consequences of this interaction and assess its potential effects. There are different types of approaches forinvestigating the toxic effects of NPs on plants. Chlorophyll fluorescence (ChlF) is one of interesting biophysicalmethods for testing the effects NPs on plants in vivo. ChlF is a suitable technique and a very powerful tool for the invivo studying of photochemical and non-photochemical processes within thylakoid membranes, chlo- roplasts,plant tissues, and whole plants. The present work reports the in vivo observation of chlorophyll a fluorescencequenching induced by the iron (Fe3O4, Fe2O3) and aluminum oxide (Al2O3) nanoparticles. Excitation andemission spectra of intact leaves of Elodea were acquired by fluorescence spectrophotometer (Cary Eclipse) atroom temperature. It was shown that the inten- sity of the ChlF decreased in the solution of Fe3O4 and Al2O3 nanoparticles on the light. Fe2O3 af- fected slightly and the toxicity of nanoparticles depended on dose andexposure period. It was clear from these experiments that the given nanoparticles penetrated into the cell and might de- crease the chlorophyll content of leaves.
