The European Commission Joint Research Centre (JRC), supported by the Nanotechnology Industries Association (NIA) and its member company BASF, has published the second report in a series on the NM- Series of Representative Manufactured Nanomaterials. Entitled NM- Series of Representative Manufactured Nanomaterials: Zinc Oxide NM-110, NM-111, NM-112, NM-113 Characterisation and Test Item Preparation, the report is the second publication documenting results obtained under the OECD WPMN Sponsorship Programme on the Safety Testing of Manufactured Nanomaterials.
The report provides a general introduction to 'Zinc Oxide' nanomaterials (NMs), the 'NM-Series of Representative Manufactured Nanomaterials and the OECD Sponsorship Programme', including information on the 'OECD Working Party for Manufactured Nanomaterials' and the 'Characterisation of Representative Nanomaterials'. Further into the report are presented the results of detailed analyses of characterisation and test item preparation conducted on NM-110, NM-111, NM-112, and NM-113 for RMN Zinc Oxide, as adopted under the OECD Sponsorship Programme.
'The present report describes the characterisation of NM-110, NM-111, NM- 112, and NM-113, RMN Zinc Oxide substances, originating from defined batches of commercially manufactured material. The NM-Series materials were subsampled in collaboration with the Fraunhofer Institute for Molecular and Applied Ecology (Fh IME), in order to be made available for measurement and testing for hazard identification, risk and exposure assessment studies'.
'The results for more than 15 endpoints are addressed in the present report, including physical-chemical properties such as size and size distribution, crystallite size and electron microscopy images. Sample and test item preparation procedures are addressed. The RMNs are studied by a number of international laboratories'.
As stated in the introduction of the publication, '[t]he properties of the Zinc Oxide RMNs NM-110, NM-111, NM-112, and NM-113 described in this report demonstrate their relevance for use in measurement and testing studies of nanomaterials. The studies were performed in close collaboration between the PROSPECT consortium partners, the JRC, the Fraunhofer Institute for Molecular and Applied Ecology (Fh-IME), BASF AG Ludwigshafen, LGC standards, the UK National Physical Laboratory (NPL), the Danish National Research Centre for the Working Environment, the Austrialian Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the National Measurement Institute of Australia'.
