- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC100
- Effect conc.:
- > 10 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC0
- Effect conc.:
- ca. 10 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Validity criteria fulfilled:
- yes
- Conclusions:
- Castor oil, hydrogenated (HCO) was not toxic to zebra fish as determined during a 96-h acute toxicity test using concentrations ranging from 1,000 mg/L to 10,000 mg/L. The LC50 and LC100 were both determined to be greater than 10,000 mg/L and the LC0 was 10,000 mg/L.
