- 72 h
- Dose descriptor:
- EC50
- Effect conc.:
- 249.335 mg/L
Applicant's summary and conclusion
- Conclusions:
- According to the Danish (Q)SAR Database predicted report, the predicted result is: 72h - EC50 (algae) = 249.3349 mg/L, based on the EC50 value, the target chemical is considered to be nontoxic and not classified as per the CLP classification criteria.
