Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- Under the conditions of this test, the test material was determined to show no effects to Daphnia Magna and therefore the NOEC concentration has been set at 1000 mg/L which was the maximum concentration that was tested.
- Executive summary:
The study has been conducted according to OECD guideline No. 201. Under the conditions of this test, the test material was determined to show no effects to the Selenastrum capricornutum and therefore the NOEC concentration has been set to 1000 mg/L, which was the maximum concentration used in this study.
