Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

The poorly soluble substance Vanadium zirconium yellow baddeleyite is evaluated by comparing the dissolved metal ion levels resulting from the transformation/dissolution test after 7 d (acute) and 28 d (chronic) at a loading rate of 1 mg/L with the lowest acute and chronic ecotoxicity reference values (ERVs) as determined for the (soluble) metal ions, respectively. The ERVs are based on the lowest EC50/LC50 (acute) or NOEC/EC10 (chronic) values for algae, invertebrates and fish. Since zirconium ion concentrations remained below the LOD during the T/D test and are well below respective ecotoxicity ERVs, only vanadium concentrations are taken into account. The dissolved vanadium concentration of 3.1 microg/L in the T/D test after 7 days at pH 8 (i.e. the pH that maximizes the dissolution) is significantly lower than the short-term ERV of 693 microg/L (Vanadium Consortium, 2020). Hence, the substance Vanadium zirconium yellow baddeleyite is not sufficiently soluble to cause short-term toxicity at the level of the acute ERVs (expressed as EC50/LC50).


The dissolved vanadium concentration of 2.8 microg/L in the T/D test after 28 days at pH 8 (i.e. the pH that maximizes the dissolution) is significantly lower than the long-term ERV of 203 microg/L (Vanadium Consortium, 2020). Hence, the substance Vanadium zirconium yellow baddeleyite is not sufficiently soluble to cause long-term toxicity at the level of the chronic ERVs (expressed as NOEC/EC10).


In accordance with Figure IV.4 “Classification strategy for determining acute aquatic hazard for metal compounds” of ECHA Guidance on the Application of the CLP Criteria (Version 5.0, July 2017) and section 4.1.2.10.2. of Regulation (EC) No 1272/2008, the substance Vanadium zirconium yellow baddeleyite is poorly soluble and does not meet classification criteria for acute (short-term) aquatic hazard. In accordance with Figure IV.5 „Classification strategy for determining long-term aquatic hazard for metal compounds “of ECHA Guidance on the Application of the CLP Criteria (Version 5.0, July 2017) and section 4.1.2.10.2. of Regulation (EC) No 1272/2008, the substance Vanadium zirconium yellow baddeleyite is poorly soluble and does also not meet classification criteria for chronic (long-term) aquatic hazard.
