Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The LC50 in juvenile rainbow trout following exposure for 96hrs to 1272W94 was >180mg/L
- Executive summary:
1272W94 was tested for its acute toxicity to juvenile rainbow trout using OECD Guideline 203. Following 96hr exposure the LC50 was determined to be >100mg/L and a NOEC estimated as <10mg/L
