A new article has been published in Environmental Pollution demonstrating the toxicity of silver nanoparticles to Lemna minor (or duckweed) which is a key component of the river ecosystem. An experimental approach was used to investigate the effect of both concentration and size of silver nanoparticles to the plant under test conditions. Growth measurements proved that the nps were toxic at low concentrations and that size of the np was important.
· Silver nanoparticles wer shown to pose a potential environmental risk based on modelled environmental concentrations.
