The European Commission’s (EC) Joint Research Centre (JRC) has published a report, entitled Towards a review of the EC Recommendation for a definition of the term ‘nanomaterial’ – Part 2: Assessment of collected information concerning the experience with the definition. It builds on the first report in the series, which presented a compilation of information received on how stakeholders found using the EC recommended definition.
The authors note that ‘it became obvious from the feedback collected by the JRC that there is a need to clarify a number of issues around and inside the definition’; the report therefore looks to address these areas. They also look at the ‘possible reasons for, and consequences of, expanding the current definition – which covers only particulate matter – towards inclusion of other types of nanostructured materials’.
‘This second report puts the EC nanomaterial definition in[to] perspective by comparing it with other existing nanomaterial definitions’, with the authors determining that ‘probably the most distinguishing aspect of the EC definition is the use of particle size distributions based on the numbers of particles, and not on the mass or volume of the particles, as the main classification feature’. The main challenges facing the implementation of the definition are also analysed.
According to the report, ‘the JRC is now working on a set of indications on how the definition could be modified to improve its clarity, effectiveness and implementability’. These are set to be included in the final report in the series, due to be published later this year.
