Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The 48h-EC50 was 12mg/l ( 95% confidence interval between 11 and 14 mg/l)
Executive summary:

Under the conditions of the present study, the test substance did not induce acute immobilisation of Daphnia magna at or below 5.1 mg/l after 48 hours of exposure (NOEC).

The 48h-EC50was 12mg/l ( 95% confidence interval between 11 and 14 mg/l)
