Characterization of Nanoparticles in Seawater for Toxicity Assessment Towards Aquatic Organisms

摘要

The fate and the behaviour of nanoparticles in seawater, which is the ultimate sink for any release of nanoparticles, is a very important issue for the assessment of their environmental impact. Despite this concern, only few studies regarding the ecotoxic effect of NPs upon marine organisms were conducted. In this work the dispersion behaviour of NPs in a seawater matrix has been investigated and their physicochemical properties characterized. The ecotoxico-logical impact towards marine organisms of several nanoparticles has been also examined.
