Specific Advice on Exposure Assessment & Hazard/Risk Characterisation for Nanomaterials under REACH


REACH-NanoHazEx (RIP-oN3) was a project funded between 2010-2011 by the Institute for Health and Consumer Protection (IHCP) of the European Commission’s Directorate General Joint Research Centre (JRC), led by SAFENANO.

The project consortium, which was a partnership between SAFENANO, the Nanotechnology Industries Association, Cefic, and Soluzioni Informatiche, brought together internationally renowned experts from disciplines including physical sciences, life sciences, occupational hygiene, and risk assessment.
REACH-NanoHazEx concerned exposure assessment and hazard/risk characterisation for nanomaterials within REACH.
The objectives of this project were to:
  • Develop advice on how to do exposure assessment for nanomaterials within the REACH context. This was the main focus of project and covered:
    • development of exposure scenarios,
    • evaluation of operational conditions and risk management/mitigation measures and
    • exposure estimation;
  • Develop ideas for how to conduct hazard and risk characterisation for nanomaterials. The latter involved both threshold and non-threshold considerations.

The final project report is available to download here.

Based on the scientific and technical state of the art recommendations made in the final reports of the RIP-oN 2 & RIP-oN 3 projects, on the 30th April 2012 the European Chemicals Agency (ECHA) published three new appendices, updating Chapters R.7a, R.7b and R.7c of the Guidance on Information Requirements and Chemical Safety Assessment (IR & CSA) with recommendations for registering nanomaterials under REACH.
