Commission releases revised nanomaterial definition

The EU has published its updated nanomaterial definition, replacing the original 2011 text after a multi-year review process involving three JRC studies and a formal stakeholder consultation.Key changes address longstanding ambiguities around particle size boundaries, the particle number concentration threshold, and the treatment of materials like graphene and carbon nanotubes.A guidance document to support implementation is due before year end, and NIA members can access a dedicated factsheet breaking down what has changed and what it means in practice.

The assessment of the environmental behaviour of the registered zinc oxide nanoforms concluded by Germany

German regulators have concluded that zinc oxide nanoforms carry the same aquatic toxicity classification as other zinc compounds, but stopped short of ruling out particle-specific effects that could add to their overall hazard profile.The finding that toxicity varied between individual nanoforms points to the complexity of treating nanoforms as a single regulatory category, a question with broad implications for how nanomaterials are classified across the EU.
