Toxicity evaluation of silver nanoparticles on aquatic and soil organisms

Popis výsledku v původním jazyce

The aim of this paper is to assess the ecotoxicity of silver nanoparticles and silver nitrate on aquatic and terrestrial organism as well as compare the sensitivity of selected organisms to the test substance. We also aimed to find out the toxic effect of AgNPs in terms of particle size. Silver nanoparticles (AgNPs) are nowadays used in a wide range of products for its antimicrobial activity. The increasing production and use of nanoparticles results in their higher concentrations in the environment. Therefore, investigating the potential aquatic and terrestrial toxicity of nanomaterials has become an important issue. In this study we investigated the toxicity of two nanosilver suspensions of varying particle sizes (2.7?6.5 d.nm) and silver nitrate on organism representing the aquatic (Daphnia magna) and soil (Folsomia candida) ecosystem. Experiments were carried out methodologically in accordance with the following standards: OECD 201 (Inhibition of the mobility of Daphnia magna) and OECD 232 (Inhibition of reproduction of Collembola Folsomia candida). Daphnia magna was much more sensitive to AgNPs and silver ions than springtail. The low EC50 (?g.L-1) values show high toxicity to Daphnids.
