It is generally assumed that the use of nanomaterials will further increase which will result in an increase in emissions of nanomaterials into the environment and concerns are being expressed whether nanomaterials wouldn?t pose a serious environmental threat. Up to now, little is known about the potential effect of nanomaterials on the environment. Ecotoxicological data concerning nanomaterials are also generally lacking at present but already published researches concerning mainly aquatic organisms have shown that in many cases nanomaterials may pose an increased health and environmental risk if compared to bulk forms of the same substances. However, the fate and behavior of nanomaterials in the environment is a very complex issue and is influenced by many factors. An evaluation of acute toxicity of four oxides (CuO, MgO, TiO2 and ZnO) was made, each substance in nano and bulk form. Two different organisms were used, freshwater crustacean Daphn" .
