Description of key information

Divanadium pentaoxide was tested by Japanese Authorities under Japan Existing chemicals survey program in CSCL. The study followed the OECD 305 guideline with no deviation and was then judged acceptable to showed that V2O5 did not bioaccumulate in fish species. The BCF found with a concentration of 50 µg V2O5/ L in the environment was 13. This reliable value was kept as key value for chemical safety assessment.

The study from Holdway supports the Japanese value with a BCF varying from 27.9 to 11.6 for 0.041 mg/L to 0.48 mg/L concentrations of vanadium in water.

BCF of vanadium is thus at the low end of the range for metals, and the bioaccumulation danger from vanadium thus appears to be low.
