Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
In this 48 hours static acute toxicity test with Daphnia magna the 48 hours EC50, EC100 and LOEC was determined to be higher then 100 mg/L, while the NOEC is 100 mg/L (nominal). The results are based on the nominal concentration.
