Environmental Fate of ENMs: Biota Compartment
Biota are the final environmental receptors of ENMs that are released into the environment. As such they are considered by NanoFASE to be a compartment.
Different species may accumulate EMNs from soil, water and/or sediment. Furthermore, biota may act as a reactor by transforming the properties of the EMNs during their residence in the organisms, or by altering the environment by their activities (e.g bioturbation), or by excretion or bio-elimination of e.g. biomolecules (as in the case of plants).
Assessment of accumulation of ENMs in biota is essential for thorough assessment and management of risks that ENMs may pose to the environment.
