Short-term toxicity to fish
Administrative data
Link to relevant study record(s)
- Endpoint:
- short-term toxicity to fish
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- REPORTING FORMAT FOR THE ANALOGUE APPROACH
Refer to attached document - Reason / purpose for cross-reference:
- read-across source
- Key result
- Duration:
- 96 h
- Dose descriptor:
- NOEC
- Effect conc.:
- >= 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- other: water-accommodated fraction (WAF)
- Basis for effect:
- behaviour
- Key result
- Duration:
- 96 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- other: water-accommodated fraction (WAF)
- Basis for effect:
- mortality (fish)
- Validity criteria fulfilled:
- yes
- Conclusions:
- Available data from 1-Octadecanol, phosphate, potassium salt were used to evaluate the acute toxicity on fish for Phosphoric acid, C12-18-alkyl esters, potassium salts.
In a 96-h acute toxicity study, Danio rerio were exposed to the read-across substance 1-Octadecanol, phosphate, potassium salt at concentrations of 0 and 100.0 mg/L nominal (WAF of 100 mg/L) under static conditions.
The 96h-LC50 was determined to be > 100 mg/L (WAF based on nominal concentration).
The 96h-NOEC was determined to be ≥ 100 mg/L (WAF based on nominal concentration).
