WP 2: ENP environmental behaviour and fate modelling

WP Leader	Dr Martin Hassellöv (UGOT)
Participants	NERC, UOXF.DJ, F+B, IHPP, AXME, UGOT
Objectives	Identify required input parameters to support analysis of scenarios of current and future ENP release developed in WP6 to parameterise initial worst case exposure assessments and derive predicted environmental concentrations for receiving aquatic and soil ecosystems. (Main participants: NERC, F+B, UGOT) Develop experimental methods to study ENP-environment interactions and their consequences for ENPs fate and behaviour through wastewater and sewage treatment processes including in receiving natural waters and sludge. (Main participants: UGOT, NERC, UOXF.DJ, IHPP) Apply refined experimental approach to investigate the effects of particle properties on ENP fate and behaviour through wastewater treatment processes and associated effluents. (Main participants: UGOT, NERC, UOXF.DJ, IHPP) Track effects of particle properties and environmental physicochemical properties on the rates of dissolution of ENPs during wastewater treatment and in a range of natural soils and waters. (Main participants: UGOT, UOXF.DJ, IHPP) Iteratively incorporate available information on ENP-environment interactions and their consequence for ENPs fate into the developed exposure models allowing for a refined PEC for waters and soils. (Main participant: NERC)
Tasks	2.1) Development and refinement of Fate models. 2.2) Studies of ENP fate and behaviour through the wastewater treatment processes. 2.3) Building an understanding of how ENP properties and wastewater treatment processes and capability affect the final treatment success and fate of ENPs under current and predicted future loads.
