OECD joint meeting: Sept 12-13

Scientific workshop on Grouping of Nanomaterials.  NanoReg2 and Gracious projects

September 12-13, 2018. Paris

NanoReg2 has joined forces with the OECD Working Party for Manufactured Nanomaterials and H2020 Gracious project to deliver a 2 day workshop.

Following a WPMN meeting on September 11, focussed on Physico-Chemical Parameters Framework for the Risk Assessment of Nanomaterials, NanoReg2 and Gracious will host a 2 day ‘Scientific workshop on Grouping of Nanomaterials’.  The workshop will feed in results from WPMN and bring together international experts to discuss and recommend how groups of nanomaterials can be developed around Pchem and hazard parameters.


Wednesday 12 September

1630 Breakout sessions - Grouping frameworks

Thursday 13 September


Breakout sessions (Hosted twice during 2 morning sessions)

  • Breakout 1: What they are.
  • Breakout 2: Where they go and what they do (human)
  • Breakout 3: Where they go and what they do (ecotox)

Session 4: Reporting from breakouts on day 1 and 2

Moderator: Mar Gonzalez, OECD

  • Where they go and what they do (ecotox)

Final panel discussion

Moderators: Andrea Haase, Wendel Wohlleben, Erik Bleeker, Nicholas Manier and Vicki Stone

The closing session generates discussion on the conference outcomes from breakout sessions, long term global objectives and the roadmap forwards for effective implementation through multiple routes.


Concluding comments and close

  • Peter Kearns, OECD (FR)


Meeting deliverables

The workshop will generate recommendations on nanomaterials grouping intended to support regulatory and standards development and implementation world-wide.  Outcomes will be published and promoted to all stakeholders involved in nanomaterials production and regulation.

Who should attend?

This meeting invites participation from stakeholders with experience in nanomaterials grouping and Pchem/hazard assessment.  Participants are expected to actively participate is discussion and recommendations and places are limited.  Participation is free of charge and delegates will be expected to cover their travel and accommodation costs.
