ABSTRACT
This chapter discusses and compares different approaches to evaluating the impact of engineered nanomaterials in different saltwater ecosystems and organisms. In comparison with freshwater ecosystems, the complexity of marine environment needs a deeper understanding. Its relationships with nanocolloids are still poorly defined. Only in recent years, in fact, has a search for valuable model organisms and more systematic in vivo and in vitro studies improved the knowledge. Unfortunately, the largest part of experimental research is done at the lab facilities, where the environmental simplification limits in part the significance of data. We simply do not have data nor suitable methods for a consistent approach and mapping of nanomaterials in natural marine environments. A newer way to fill the gap could be a more suitable use of mesocosms, until now limited to brackish, estuarine environment.
