Additional information

Conclusion on classification

The substance is not acutely toxic to aquatic organisms and has no significant bioaccumulation potential. Biodegadation is not applicable as the substance is inorganic and has an extremely low solubility. Thus the substance is not labelled as dangerous for the environment.

Furthermore, the maximum dissoluted/transformed vanadium concentration was 9 µg/L at a loading rate of 100 mg/L, at pH 8.5 and after 7 days. This concentration is far below the environmental refence values (ERV) for vanadium which are 693 µg V/L (acute ERV) and 120 µg V/L (chronic ERV). The ERVs were taken from the disseminated dossier for V2O5, CAS 1314 -62 -1, where all available studies with vanadium compounds are sumnmarized. The ERVs are based on the most sensitive acute and chronic endpoints derived by standard tests with standard species. Based on the transformed/dissoluted vanadium concentration from bismuth vanadium tetraoxide and compared with the ERVs for vanadium acute and chronic classification for the substance have not to be applied. Furthermore, due to the very low transformation/dissolution concentration of vanadium an environmental hazard to all environmetal compartments is very unlikely.
