Constituent 1
Results and discussion
Effect concentrations
- Key result
- Duration:
- 72 h
- Dose descriptor:
- EC50
- Effect conc.:
- >= 100 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat. (dissolved fraction)
- Basis for effect:
- growth rate
- Remarks on result:
- other: * It was not possible to calculate an ErC50 value as no concentration tested resulted in 50% inhibition of growth rate.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The effect of the test item on the growth of Pseudokirchneriella subcapitata has been investigated and gave EC50 values of greater than 100 mg/L. The No Observed Effect Concentration was 10 mg/L.
