Status update transformation/dissolution testing

As previously communicated on August 27, 2020 via REC website, a compliance check decision was received for dierbium trioxide (EC 235-045-7, CAS 12061-16-4, final decision dd 21 January 2019;). As a result of this decision – among others – a Transformation/Dissolution study (T/D, OECD 29) had to be performed, to cover the endpoint ‘water solubility’ as well as to determine the environmental classification of the substance.
