Abstract

Nanomaterials of different chemical composition, physicochemical properties, and origins are emitted to the environment because of their wide use and incidental emission. Water suspended aggregates in the nanorange can be processed with conventional wastewater treatments, but their efficiency seems to vary according to the characteristics of the aggregates. Moreover, even in the best case scenario, certain amounts of nanomaterials are likely to be present in the effluent flows at trace concentrations. Sewage water disposal together with other processes, such as the atmospheric deposition and the direct spillage risk, make the water environment particularly susceptible to the introduction of these new compounds and carry ecological and health consequences that should be assessed.

Studying the behavior of nanoparticles in water environments of ecological relevance is a crucial step toward a proper assessment of the ecotoxicological effects, distribution patterns, and persistence of nanomaterials in the water environment.
