The Nanotechnology Industries Association (NIA) is hosting a symposium on 'Grouping & Read-Across for Nanomaterials', to be held in Brussels (Belgium) on 26 Nov 2013. It will be followed by the Association's Annual General Meeting (attendance for NIA Members only).
Two years after the European Commission published its ‘Recommendation on the Definition of Nanomaterial’ (for regulatory and policy purposes), which deems an estimated 50% of all commercially-used materials to be ‘nanomaterials’, the stakeholder groups most responsible for the implementation of characterisation and testing are urging a move away from the currently recommended case-by-case analysis of individual nanomaterials to a more efficient and sustainable approach.
In order to facilitate this move, several questions are being addressed:
- How can nanomaterials be ‘grouped’ or ‘categorised’ so as to:
- reduce the number of measurements and tests that need to be performed;
- allow for a ‘safety-by-design’ approach; and
- identify the relevant Substance Identity (SID)?
- Which parameters play a role in the grouping of nanomaterials (i.e. physchem characteristics, hazard profiles, bioavailability, etc.)?
- How can ‘read-across’ from the bulk form of a material be applied to a nanomaterial of the same chemical composition (and vice versa)?
