The aim of this research was to observe the relationship between zeta potential, morphology, surface area, porosity, chemical composition, and ecotoxicity of nanocomposite powders such as Au/TiO 2 , Ag 2 O/TiO 2 , PdO/TiO 2 , Ag/TiO 2 /SiO 2 , Ag/N(C)TiO 2 , and SiO 2 /TiO 2 from which Ag 2 O/TiO 2 , Ag/N(C)/TiO 2, and Ag/TiO 2 /SiO 2 were exhibiting good antimicrobial properties. It was observed, that nanomaterials characterized by similar morphology and zeta potential revealed the similar toxic behavior. The samples of higher agglomeration and higher zeta potential, especially Ag/TiO 2 /SiO 2 xerogel and TiO 2 /SiO 2 aerogel were generally less ecotoxic to water organisms and plants. They were also not genotoxic in concentrations up to 500 and 250 mg/L, respectively.
