Considered a good source of water soluble vanadium for aquatic testing. - Analytical monitoring:
- yes
- Details on sampling:
- Samples for vanadium analysis were also collected at the start and end of each test to quantify actual exposure concentrations.
- Vehicle:
- no
- Test organisms (species):
- Scenedesmus quadricauda
- Details on test organisms:
- Scenedesmus quadricauda was identified as a regionally-representative green algal species
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 72 h
- Hardness:
- ca 110 mg/l CaCO3
- Test temperature:
- ca 23 C
- pH:
- ca 8.6
- Details on test conditions:
- Reconstituted water in continuous lighting
- Reference substance (positive control):
- no
- Duration:
- 72 h
- Dose descriptor:
- IC50
- Effect conc.:
- ca. 4.12 mg/L
- Nominal / measured:
- meas. (arithm. mean)
- Conc. based on:
- element
- Remarks:
- Vanadium
- Basis for effect:
- growth rate
- Key result
- Duration:
- 72 h
- Dose descriptor:
- IC50
- Effect conc.:
- ca. 14 mg/L
- Nominal / measured:
- estimated
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Remarks on result:
- other: Starting with IC50 4.12 mg/l for V and using molecular weight of constituent with greatest proportion of vanadium
- Details on results:
- The reported IC50 (growth rate) was in the range of 3.06 - 4.85 mg/l, with an EC10 of 0.27 mg/l vanadium, suggesting a shallow dose response.
Vanadium is considered to be an essential element for plants. - Conclusions:
- Using a molecular weight of 173 for the registered substance, the IC50 has been estimated to be > 10 mg/l
