The Netherlands National Institute for Public Health and the Environment (RIVM) published on June 29, 2012, a report entitled Interpretation and implications of the European Commission Recommendation on the definition of nanomaterial. The Dutch ministries requested RIVM to interpret the meaning and implications of the European Commission’s (EC) recommendation from a scientific perspective and to consider the implications for use in legislation. RIVM intends the report to provide the basis for discussions by policy makers and stakeholders on the use and further implementation of the recommended definition in national and international legal frameworks. RIVM concludes that, while the EC’s recommendation contains the relevant aspects, further guidance is necessary to ensure the definition is interpreted consistently. According to RIVM, the next step is to incorporate the definition into legal frameworks regarding the interpretation of the term nanomaterial. RIVM states that this will lead to the collection of “nano-specific” data, contributing to further insight into the “nano-specific” properties and the fate, kinetics, and effects of nanomaterials. This will help focus on the specific needs for risk assessment and risk management of nanomaterials.
