Applicant's summary and conclusion

Validity criteria fulfilled:

not specified

Conclusions:

The test item did not cause any mortality at 10 mg/L (nominal) within 96 h. The 96-h LC50 was determined >10 mg/L for Leucisdus idus. The LC50 to fish is above the water solubility limit of the test item.
