Applicant's summary and conclusion

Validity criteria fulfilled:

yes

Conclusions:

The EC50/48 hours of Tamip monoamid (ZK 39.211) to Daphnia magna is higher than 10 g/L.

Executive summary:

20 Daphnia were exposed to the test substance and a dilution water control for a period of 48h. The test concentration in the limit test was 10 g/L. No abnormalities related to the exposure to the test compound were observed. The EC50/48 hours was higher than 10 g/L.
