Updated advice on testing nanomaterials
3 February 2023

European Chemicals Agency (ECHA) has released an updated appendix for nanomaterials, which provides guidance on how to obtain data under the new information requirements for nanoforms. This includes information on how to perform environmental testing and advice on preparation methods and testing strategies for physico-chemical testing of nanoforms.

Nanomaterials and health
