Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- toxicity range available
- Conclusions:
- In a acute fish test with rainbow trout no mortality was observed at the limit test concentration of 0.1 mg/L. In a range finding test also at 0.1 mg/L no mortality was observed but at 1 mg/L 100% mortality occured.This means the LC50 (96h) is in the range of 0.1 and 1 mg/L. This result is regarded as sufficent as a chronic fish test result with a NOEC of 0.1 mg/L is available (see IUCLID Chapter 6.1.2).
