Description of key information

The lowest 48-h L(E)C50 for freshwater invertebrates (1520 µg V/L) was observed for the effect of V2O5 on mortality of Daphnia magna in hard water (Kimball, 1978; Klimisch 2).
For the marine environment, a 48-h LC50 value of 13300 µg V/L was reported for the acute effect of NaVO3 on the mysid shrimp Americamysis bahia in adjusted natural seawater (Woods et al., 1984; Klimisch 1).

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
1 520 µg/L
EC50/LC50 for marine water invertebrates:
13 300 µg/L

Additional information

Several reliable studies (Klimisch 1 or 2) are available on the acute toxicity of vanadium substances on Daphnia magna. Reliable 48-hour L(E)C50 values for mortality and immobilisation vary between 1520 and 4033 µg V/L across studies and substances tested (NaVO3, V2O5, and ammonium polyvanadate). No results are available for other freshwater invertebrates. Results were not averaged across substances and the lowest value was selected for the chemical safety assessment.

One reliable study reports the short-term toxicity of vanadium to marine invertebrates. Woods et al. (1984) report an 48-h LC50 value of 13300 µg V/L for the acute effect of NaVO3 on the mysid shrimp Americamysis bahia in adjusted natural seawater (Klimisch 1). All results are based on total dissolved V concentrations.
