Highlight of two special activities The parallel activity The workshop for Member States Information on the parallel activity 5 Aims and scope of the parallel activity Reminder

While the eventual choice of tools for regulatory purposes will be made by Member states, it is important that all bioavailability tools meet a minimum standard of performance in terms of precision and applicability domain relative to the full BLMs that were used to derive the EQS (ToR of the parallel activity) to compare for Ni, Cu, Zn and Pb the outputs from the tools against each other and to the respective full BLM outputs to identify if there is any systematic difference between the predictions and the physic-chemical conditions under which these differences occur, find possible reasons for these differences to provide some recommendations on how to use the tools (based on the above considerations), and on how to further increase the

comparability of the tools in their future updates Who was involved? Developers of the simplified tools Jos Vink (Deltares) Anja Verschoor (RiVM) Adam Peters (WCA) Chris Schlekat (NiPERA) Frank Van Assche (IZA) Experts from Member states Henning Clausen (DK)

Matti Leppnen (FI) Anja Duffek (DE) Heinz Rdel (Fraunhofer Institute, DE) Additional experts Karel De Schamphelaere (U Gent) Frederik Verdonck (Arche consulting) Chairs Olivier Perceval (FR) Dorien ten Hulscher (NL)

What was compared? PNEC pro Bio-met The result of this activity: Guidance chapter RCO M
