Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Based on the conditions of the study, the EC50 for Daphnia was determined to be >22 mg/L and <46 mg/L.
- Executive summary:
The acute toxicity to D. magna of water accommodated fractions of VERSATIC 1019 was determined in a 48 h static toxicity test . The test was conducted in sealed test vessels. The findings of an GLP, O.E.C.D. 202 Testing Guideline study with Daphnia magna conducted under static conditons of exposure demonstrated that the 48 - hr EC50 value was >22 mg/L and <46 mg/L.
