72 h
Key result
Duration:
72 h
Dose descriptor:
EC50
Effect conc.:
> 36 600 mg/L
Remarks on result:
other: QSAR predicted value
Validity criteria fulfilled:
yes
Conclusions:
72-hour EC50 (green algae): >36600 mg/L
Executive summary:

The Neutral Organic Baseline Toxicity for Green Algae 72-h EC50 model was used to predict the acute toxicity to green algae. The 72-hour EC50 in green algae was predicted to be >36600 mg/L. Additional supporting documentation is provided in the prediction report attached in IUCLID.
