German EPA publishes Report on Nanomaterial Phys-Chem Properties and Aquatic Toxicity for Grouping

The German Umweltbudesamt (Environment Protection Agency) has published a report on Considerations about the relationship of nanomaterial’s physical-chemical properties and aquatic toxicity for the purpose of grouping. The publication presents an analysis of the physical-chemical properties of fourteen different subtypes of nanoscale silver, zinc oxide, titanium dioxide, cerium oxide and copper, the properties of these materials have been measured and they have been tested for ecotoxicity in aquatic media using OECD guidelines.

From this 'comprehensive and systematic testing of ecotoxicity and PC-parameters', Umweltbundesamt has identified relationships and limitations to support further regulatory grouping of nanomaterials. The report also lists recommendations to support further correlations between physical-chemical properties and ecotoxicity of nanomaterials.
