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:
- 10-24 July 1992
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 203 (Fish, Acute Toxicity Test)
- GLP compliance:
- yes
- Analytical monitoring:
- no
- Details on sampling:
- The substance is readily soluble and stable in water. Analytical monitoring was therefore considered unnecessary.
- Vehicle:
- no
- Test organisms (species):
- Danio rerio (previous name: Brachydanio rerio)
- Test type:
- semi-static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 96 h
- Reference substance (positive control):
- no
- Key result
- Duration:
- 96 h
- Dose descriptor:
- LC50
- Effect conc.:
- > 1 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- mortality (fish)
- Validity criteria fulfilled:
- yes
- Conclusions:
- No mortality was observed at 1000 mg/l. The LC50 is >1000 mg/l
- Executive summary:
The toxicity to fish was determined acording to the OECD 203 test guideline in accordance with GLP, with exposure to Brachydanio rerio (new name: Danio rerio) at a test concentration of 1000 mg/l. As the substance is highly water soluble and hydrolytically stable no analytical monitoring was conducted. Following a 96 hour exposure, no mortality occured. The LC50 is >1000 mg/l.
