Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to fish
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 96 hours (but extended to 7 Day exposure)
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Justification for type of information:
- Publication describing methods and results in detail.
Chronic toxicity also described in the same report - Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 203 (Fish, Acute Toxicity Test)
- Version / remarks:
- Extnded period to 7 days
- Principles of method if other than guideline:
- Source of vanadium is described as predominantly sulphate, but oxy-sulphates and other salts will exist in the water column tested.
Results are expressed as vanadium.
Different valencies will also exist depending on pH
The report makes it clear that the vanadium form will be difficult to monitor and will change under conditions of analysis.
It is assumed that the vanadium under the test conditions would be penta-valent at the pH of the assessment - GLP compliance:
- no
- Specific details on test material used for the study:
- Not described, but taken from mine workings
- Analytical monitoring:
- yes
- Details on sampling:
- Analysis for vanadium
- Vehicle:
- no
- Details on test solutions:
- Source of vanadium is described as predominantly sulphate, but oxy-sulphates and other salts will exist in the water column tested.

The report makes it clear that the vanadium form will be difficult to monitor and will change under conditions of analysis.
It is assumed that the vanadium under the test conditions would be penta-valent at the pH of the assessment - Test organisms (species):
- Oncorhynchus mykiss (previous name: Salmo gairdneri)
- Details on test organisms:
- Described as Canadian salmonid fish (Salmo gairdneri)
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 7 d
- Remarks on exposure duration:
- Report includes extended toxicity work in Section 6.1.2
- Hardness:
- Range of hardness from 30, 100, and 360 mg/l as CaC03
- Test temperature:
- 15 C
- pH:
- pH 5.5, 6.6, 7.7, and 8.8, with the highest pH associated with the hardest water
- Reference substance (positive control):
- no
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- ca. 6 mg/L
- Nominal / measured:
- meas. (initial)
- Conc. based on:
- element
- Remarks:
- Vanadium
- Basis for effect:
- mortality (fish)
- Remarks on result:
- other: pH 7.7, hardness ca 100 mg CaCO3
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- > 10 mg/L
- Nominal / measured:
- meas. (initial)
- Conc. based on:
- element
- Remarks:
- Vanadium
- Basis for effect:
- mortality (fish)
- Remarks on result:
- other: For low or high hardness, or low or high pH
- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- ca. 17.3 mg/L
- Nominal / measured:
- estimated
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Remarks on result:
- other: Starting with LC50 of 5.1 for V and using molecular weight of constituent with greatest proportion ov vanadium
- Details on results:
- Due to the variance in hardness and pH for this research, a number of LC50s are cited. Typically, for ca pH 7 the toxicity seemed greater with an LC50 of 5.1 mg/l - 7.7 mg/l. At higher or lower pH, the toxicity appeared less severe, with solublity perhaps influencing the effects at higher pH.
- Conclusions:
- Due to the variance in hardness and pH for this research, a number of LC50s are cited. Typically, for ca pH 7 the toxicity seemd greater with an LC50 of 5.1 mg/l - 7.7 mg/l). At higher or lower pH, the toxicity appeared less severe, with solublity perhaps influencing the effects at higher pH.
A headline figure of 5.1 mg/l V is used for the CSR.
This equates to ca 17.3 mg/l of VO(SO4) which is considered to be the lowest molecular weight fraction with the highest ratio of vanadium.
