Description of key information

Reliable data (all Klimisch 2) are available for three freshwater species: Pimephales promelas, Jordanella floridae and Oncorhynchus mykiss and different vanadium substances (NaVO3 or V2O5). Chronic NOEC or EC10 values range from 76 µg V/L to 1850 µg V/L. The lowest chronic NOEC/EC10 value for fish of 76 µg V/L was observed for the effect of V2O5 in a 30-day growth test with second generation flagfish larvae (Jordanella floridae) originating from exposed fish (Holdway and Sprague, 1979).

All results are based on total dissolved V concentrations.

Reliable data are not available for the long-term toxicity of vanadium substances to marine fish.
