Nanoecotoxicology: The State of the Art

Manufactured nanomaterials are used in many commercially available consumer products, such as cosmetics, textiles, and paints. Due to the increasing production volumes, environmental exposure to these materials is evident. Here, we will discuss the toxicological impact of some nanomaterials, such as ZnO, TiO2, and BaTiO3 nanoparticles on aquatic microorganisms by giving some examples. It is clear that the physicochemical properties as well as the structure and morphology of nanomaterials have a high influence on toxicity. We will emphasize the importance of nanomaterial characterization before biological tests.
