CAS number: 12070-10-9
Several reliable and GLP-conform studies (Klimisch 1 and 2) are
available for the effect of V2O5 flakes, NaVO3 and (NH4)V3O8 on the
biomass and growth rate of several freshwater algae species, including
Ankistrodesmus falcatus, Desmodesmus subspicatus, Navicula pelliculosa,
Pseudokirchneriella subcapitata and Scenedesmus quadricauda. Studies
were performed according to standard test guidelines, OECD 201 or
Environment Canada EPS 1 RM/25. Results for growth rate are preferred
for the effects assessment, and EC10 values are preferred over NOECs in
accordance with ECHA Guidance on IR & CSA, R.10 (2008). The 72-h ErC50
values for growth rate range from 2,907 µg V/L for Desmodesmus
subspicatus (Mitterer, 1999; V2O5) to 8,000 µg V/L for Navicula
pelliculosa (Wenzel, 2017). Respective ErC10 values range from 270 µg
V/L (S. quadricauda; Schiffer and Liber, 2017) to 5,720 µg V/L(N.
pelliculosa; Wenzel, 2017).
The lowest 72-h ErC50 of 2907 µgV/L was observed for the growth rate of
green alga Desmodesmus subspicatus with V2O5 flakes (Mitterer,
1999; Klimisch 2) whereas the lowest 72-h ErC10 of 270 µg/L was
determined in a study with NaVO3 for the growth rate of Scenedesmus
quadricauda (Schiffer and Liber, 2017; Klimisch 2). All
results are based on total dissolved V concentrations.
Reliable data are not available for the toxicity of
vanadium substances to marine algae.
