- Key result
- Duration:
- 96 h
- Dose descriptor:
- EC50
- Effect conc.:
- 0.895 mg/L
- Nominal / measured:
- estimated

Applicant's summary and conclusion
- Validity criteria fulfilled:
- no
- Conclusions:
- ECOSAR Version 1.11 predicts EC50 (96h) (Green Algae) = 0.895 mg/L .
But the water solubility predicted is 0.3419 mg/L, which is < 0.895 mg/L. So normally, none toxic effects should be observed to Green Algae.
In addition, the chemical is predicted to be ready biodegradable.
