EC number: 235-122-5
CAS number: 12070-10-9
Available reliable ecotoxicity results
selected for the assessment of vanadium toxicity to aquatic organisms
based on pentavalent V substances (NaVO3, Na3VO4, NH4VO3, NH4V3O8, V2O5)
and dissolved elemental V concentrations were grouped together.
Reliable short-term toxicity data for
freshwater organisms are available for three trophic levels: aquatic
invertebrates, fish and algae. The lowest acute effect value is the 96-h
LC50 of 693 µg V/L observed for the effect of V2O5 flakes on mortality
of the fish Leuciscus idus.
Acute toxicity data are also available for
marine fish and invertebrates, with the lowest acute effect 48-h LC50
value of 13,300 µg V/L for the mysid shrimp Americamysis bahia.
Reliable long-term toxicity data are
available for 17 freshwater organisms covering three trophic levels. The
lowest chronic NOEC/EC10 value of 50 µg V/L was observed for the effect
of NaVO3 in a 21-day reproduction test with neonates of the aquatic
invertebrate Daphnia dentifera. Regarding the minimum requirement of 10
chronic NOEC values (preferably more than 15) and the representation of
taxonomic groups, the data are sufficient for the derivation of the
PNECfreshwater using the statistical extrapolation approach (species
sensitivity distribution, SSD) in accordance with ECHA’s Guidance on IR
& CSA, R.10.3.1.3 (2008).
Regarding marine toxicity, reliable long-term
toxicity data are also available for the effect of V2O5 on the
development of eggs from two organisms (mollusc Crassostrea gigas and
echinoderm Paracentrotus lividus). The NOEC values range from 25 to 50
µg V/L with the lowest value of 25 µg V/L observed for the 48-h
development test of Crassostrea gigas eggs.
The lowest reliable effect concentrations for
short- and long-term toxicity of vanadium for each trophic level are
