WP 6: Integrated environmental risk assessment

WP 6: Integrated environmental risk assessment

WP leaderDr Andrew Johnson (NERC)
ParticipantsNERC, VUA, UAVR, F+B, NT, UNIPMN, IHPP, CU, UGOT
Objectives
  • Conduct literature review and a stakeholder consultation to define current and potential future uses of ENPs and determine the driving parameters (including associated uncertainties) that define plausible future release scenarios. Collate consumption/discharge information and fate information (WP2) for use in exposure modelling. (Main participants: F+B, NERC, NT, AXME, SYMLOG)
  • Conduct initial estimates of the concentrations of nanoparticles in different environmental compartments (air, sludge/soil, water and sediments) using the standard EU EUSES modelling approach based on the scenarios developed in Objective 1. (Main participants: NERC, F+B, UGOT)
  • Generate robust Predicted No Effect Concentrations (PNECs) by integration of the experimental hazard data from WP3, the bioavailability data from WP4 and ecotoxicology data from the literature with the exposure assessments to develop a sound understanding of the environmental hazards of ENPs and how environmental media (water and soil) affect this. (Main participants: NERC, VUA, UGOT)
  • Incorporate information on PNECs into multi-media (EUSES) and in GIS based models for soil (using ADMS) and receiving waters (using LF2000-WQX) to allow risk visualisation analyses for using generic and taxa specific PNEC and other endpoint data as appropriate. (Main participants: F+B, NERC)
  • Undertake appraisal of the current and potential future environmental risks of CeO 2, ZnO and Ag ENPs, based on the work conducted in WPs 2, 3, 4, 5, including gap analysis relating to the uncertainties in hazard, fate and exposure assessment as well as the use and emission scenario definitions. (Main participants: NERC, VUA, F+B, UGOT, UAVR, CU)
  • Develop appropriate project material to disseminate results and applied methodologies to relevant stakeholders, in order to improve understanding of ENP risks. (Main participants: NERC, VUA, F+B, UGOT, UAVR, CU, SYMLOG)
