NANOHETER
Fate of engineered nanoparticles in the water column under natural conditions.
Role of heteroaggregation with naturally occurring suspended matter.
Objectives of the NANOHETER Project: As part of the risk assessment of nanotechnology, this project deals with the exposure aspect of engineered nanoparticles (ENPs), focusing on their fate in surface water. Based on the trace concentrations expected to be present, the approach claims that the ENP homoaggregation in the water column is not a driving characteristic for their fate, but that the potential for interaction with mineral and organic suspended matter occurring in surface water will be the governing factor. The aim of this project is to identify the potential carriers for ENPs among these materials, with mechanistic, holistic and modelling approaches conducted concurrently. The interactions of ENPs with surrounding materials are investigated, and the potentially induced heteroaggregation and/or sedimentation mechanisms are studied. The goal is to deliver a probability ranking of these potential scenarios that can be used to model the fate of ENPs in natural aqueous systems at the river scale.
