ECOSAR v1.11 Methodology Document.
ECOSAR v1.11 Operation Manual. - Specific details on test material used for the study:
- SMILES: CC1=CC=NC=C1
- Test organisms (species):
- Daphnia sp.
- Key result
- Duration:
- 48 h
- Dose descriptor:
- LC50
- Effect conc.:
- 156.33 mg/L
- Nominal / measured:
- estimated
- Remarks on result:
- other: QSAR predicted value
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The daphnia 48-h LC50 for the test substance was predicted to be 156.33 mg/l (EPI-Suite, ECOSAR v1.11, neutral organics).
- Executive summary:
The short-term toxicity to aquatic invertebrates of the test substance was determined by using EPI-Suite, ECOSAR v1.11 class-specific estimation (neutral organics). The daphnia 48-h LC50 for the test substance was predicted to be 156.33 mg/l.
Reference
ECOSAR v1.11 class-specific estimation (neutral organics) predicted that the test substance has a 48 h-LC50 to daphnia of 156.330 mg/L.
