Applicant's summary and conclusion

Validity criteria fulfilled:

yes

Executive summary:

No significant effects (≤10% immobilization out of a total of 40 Daphnia) were observed after 24 and 48 h of exposure. Based on these results, the 24 and 48 h EC50 values of DV1 were >100 mg/l loading rate. The no-observed-effect concentrations (NOEC) for 24 and 48 h of exposure were 100 mg/l loading rate. 100% immobilization was not detected within 48 h of exposure.
