Results and discussion
Effect concentrations
- Key result
- Duration:
- 48 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat. (dissolved fraction)
- Basis for effect:
- mobility
- Remarks on result:
- other: Analysis of the test preparations at 0 and 48 hours showed measured test concentrations to range from 99% to 101% of nominal and so the results are based on nominal test concentrations only.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Analysis of the test preparations at 0 and 48 hours showed measured test concentrations to range from 99% to 101% of nominal and so the results are based on nominal test concentrations only.
Exposure of Daphnia magna to the test item gave EC50 values based on the nominal test concentration of greater than 100 mg/L. The No Observed Effect Concentration was 100 mg/L.
