Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- 24-hour EC50 = 20.5 mg/L
24-hour NOEC = 10 mg/L - Executive summary:
An acute, static 24-hour test was conducted at nominal concentrations of 0, 10, 18, 32, 56 and 100 mg/L on Daphnia magna. Exposure after 24 hours resulted in 100% immobility at 32 mg/L. Based on nominal concentration , the EC50 was 20.5 mg/L and the NOEC was 10 mg/L.
