Work carried out by the NIA-led PROSPECT project has been cited in a report recently published by the European Commission's (EC) Joint Research Centre (JRC). The publication, entitled Requirements on measurements for the implementation of the European Commission definition of the term 'nanomaterial', found that 'no currently available measurement method for nanomaterials can be universally used for determining whether the Commission's recommended definition can be fulfilled'.
Along with the Institute for Health and Consumer Protection of the JRC (JRC-IHCP) and other European research partners, the PROSPECT project studied 'several zinc oxide (ZnO) materials' for the report. These materials had been selected by the Organisation for Economic Cooperation and Development's (OECD) Working Party on Manufactured Nanomaterials (WPMN) steering group 3, 'Safety Testing of a Representative Set of Manufactured Nanomaterials'.
The ZnO materials that were studied had been produced as powders. According to the report, the results of the study 'show the difficulties in measuring agglomerated and aggregated materials', and as such are indicative of the wider issues regarding the proper implementation of the EC's recommended definition.
