Ageing, dissolution and biogenic formation of nanoparticles: how do these factors affect the uptake kinetics of silver nanoparticles in earthworms?

Discrimination between nano (≥20 nm) and ionic Ag in earthworms exposed to Ag-NPs, Ag2S-NPs and AgNO3 reveals that accumulated silver is mainly present as ions.

Proposal for a tiered dietary bioaccumulation testing strategy for engineered nanomaterials using fish

The scientific community has invested effort into standardising methodologies for the regulatory ecotoxicity testing of engineered nanomaterials (ENMs), but the practical requirements for bioaccumulation testing of ENMs have been given less attention.
