Risk Assessment Process

The study demonstrated the ecotoxic potential of lanthanum oxide nanoparticles on fresh-water aquatic microalgae Chlorella sp. and the crustacean Daphnia magna. Lanthanum oxide nanoparticles showed no toxic effects on algae and severe toxic effects on the crustacean. Results may play a vital role in the risk assessment process for exposure of lanthanum oxide nanoparticles in aquatic environments.

The use of different nanoparticles (NPs) is growing every year since discoveries of their unique properties. The wide use of nanomaterials has raised concerns about their safety and possible accumulation in the aquatic environment. Mussels are being considered as one of the most suitable organisms for bioaccumulation monitoring. Within our study, we focused on developing the method that can be applied in field studies of ecotoxicity and can be nondestructive and informative at early times of exposure, while at the same time being based on changes of physiological parameters of fresh water mussels. The changes in the cardiovascular and neural systems of mollusks (Anodonta anatina and Unio tumidus) were measured as biomarkers of toxic effects. Different monometallic and bimetallic NPs, silicon NPs with various ligands were applied as test substances. Changes in cardiovascular and neural functions were in good correlation with accumulation tests for all tested NPs.
