The acute toxicity on Daphnia was estimated by using ACD/Percepta Aquatic toxicity module (LC50
Daphnia magna QSAR model). ACD/Percepta model for aquatic toxicity calculates acute toxicity expressed
as LC50 value for water fleas (Daphnia magna), based on the GALAS methodology. The reliability of
prediction is assessed in terms of reliability index (RI).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- no
- Conclusions:
- Prediction 48-h LC50 (Daphnia magna) equal to 420 mg/l. It has not met GHS criteria. The target compound 4-nitrobenzoic acid is included in the model applicability domain
since the RI is greater than 0.3 (RI equal to 0.7). - Executive summary:
Prediction 48-h LC50 (Daphnia magna) equal to 420 mg/l. It has not met GHS criteria.
