WP 3: ENP Ecotoxicology

WP LeaderDr Susana Loureiro (UAVR)
ParticipantsNERC, VUA, UOXF.DJ, UAVR, UNIPMN, IHPP, CU, AXME, UGOT
Objectives
  • Collate information on the suitability of existing ecotoxicological tests systems for ENP testing and subsequent optimisation of the NANOFATE biotest systems. (Main participants: NERC, VUA, UOXF.DJ, UAVR, UNIPMN, CU, UGOT)
  • Ecotoxicological hazard characterisation of pure ENPs using the optimised media to establish chronic thresholds of concern (no observed effect concentrations, benchmark concentrations) for population relevant endpoints (e.g. reproduction) for selected aquatic and terrestrial test species. (Main participants: NERC, VUA, UOXF.DJ, UAVR, UNIPMN, CU, UGOT) 
  • Determination of the ecotoxicology of the selected ENP types in environmentally realistic situations for aquatic and terrestrial systems, including the assessment of interactive effects with physiochemical components of different exposure media and interactions with UV and organic chemicals as potential co-stressors. (Main participants: NERC, VUA, UOXF.DJ, UAVR, UNIPMN, UGOT) 
  • Identification of the major drivers for the ecotoxicological effects of ENPs, such as the contribution of the ENP itself and the metal ions they liberate, the coating of the ENPs after passage through STPs, the dependence on the exposed species and considered exposure route. Compilation of the experimental information and existing information from the literature and other R&D projects. Knowledge transfer to WP 4 (bioavailability studies) and WP 6 (risk assessment).

Tasks3.1) Establishment of exposure systems.

3.2) Ecotoxicological hazard characterisation of pure ENPs.

3.3) Advanced hazard characterisation of ENPs under environmentally realistic conditions, especially taking into account major confounding factors (natural media, UV and PAHs from combustion processes).

3.4) Synopsis: Identification of critical drivers for the ecotoxicology of ENPs.
