The next step towards implementing the requirements for environmental risk assessment of nanomaterials: The new standard test method investigates the solubility and dissolution rate of nanomaterials under relevant environmental conditions. It therefore represents an important new building block for an appropriate environmental risk assessment within the framework of chemical safety regulations.

Together with the Federal Office for Chemicals and the Federal Institute for Risk Assessment, the German Environment Agency (UBA) has been carrying out a REACH substance evaluation on the registered nanoforms of zinc oxide since 2017. The assessment of the data on the environmental behaviour and effects of the registered zinc oxide nanoforms is now concluded.

Up to date overview of the application of nanocarriers: Research report shows the chemical and structural diversity as well as the wide range of applications of these advanced materials in medicine, plant protection, food and other areas.

On 30th June 2022, the OECD published the Test Guideline No. 125, which harmonises the determination of particle size distribution specifically for nanomaterials. It is an important building block for the implementation of nano-specific requirements within the framework of legislation on chemical safety, for example for the REACH Regulation.

The German Environment Agency is addressing the potential of advanced materials for environmental and climate protection and is participating in discussions on the open questions on advanced materials with regard to chemical safety and the sustainability over the whole life cycle of their applications.

The OECD Test Guideline No. 318 features the very first standardized test method particular for nanomaterials adopted by OECD. It is one important component needed for the adaptation of nanospecific requirements for environmental risk assessment applied within legislations on chemical safety.

On 10th and 11th of October 2017, the German Ministry for the Environment and UBA will host a Scientific Stakeholder Meeting on Nanomaterials in the Environment at the headquarters of UBA in Dessau-Roßlau, Germany.
