The up to date increasing number of nanotechnology applications is linked with a serious danger of environmental pollution by nanomaterials. Consequently, the ecotoxicity testing of nanomaterials becomes an essential part of nanotechnology development. Classical ecotoxicity tests suffer with a number of complications when used for nanomaterials. In the case of aquatic toxicity tests, the nanoparticle agglomeration in the liquid media is a fundamental problem. The aim of this work is to evaluate the influence of important physico-chemical parameters (nanoparticle concentration and illumination conditions) on an agglomeration of 40 nm silver nanoparticles (AgNPs) in a liquid media prescribed for fish eco-toxicity test by the OECD 203 guideline (Medium 203).
