EC number: 202-589-1 | CAS number: 97-53-0
Long-term toxicity to fish
Administrative data
Link to relevant study record(s)
- Endpoint:
- fish early-life stage toxicity
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 07-2022
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- 1. SOFTWARE
ECOSAR
2. MODEL (incl. version number)
v2.2
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
COc1cc(CC=C)ccc1O
See other input values in the QPRF attached.
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
See detailed information in QPRF/QMRF attached.
5. APPLICABILITY DOMAIN
See detailed information in QPRF/QMRF attached.
6. ADEQUACY OF THE RESULT
See detailed information in QPRF/QMRF attached. - Qualifier:
- no guideline required
- Principles of method if other than guideline:
- see field 'Justification for type of information'
- Analytical monitoring:
- yes
- Remarks:
- Data included in ECOSAR are based on measured test concentrations maintained at greater than 80% of nominal concentrations.
- Test organisms (species):
- other: Fish (Ecosar includes data from various species)
- Test type:
- other: Semi-static or flow-through
- Water media type:
- freshwater
- Total exposure duration:
- 33 d
- Hardness:
- < 150 mgCaCO3/L
- pH:
- 6-8
- Key result
- Duration:
- 33 d
- Dose descriptor:
- NOEC
- Effect conc.:
- 2.015 mg/L
- Nominal / measured:
- meas. (not specified)
- Conc. based on:
- act. ingr.
- Validity criteria fulfilled:
- yes
- Remarks:
- Applicability domain of the QSAR model respected.
- Conclusions:
- The fish 32/33d-NOEC is predicted to be 2.015 mg/L.
- Executive summary:
The fish 32/33d-NOEC was predicted using the software ECOSAR v2.2 and the equation for phenols. The results indicate that the NOEC is 2.015 mg/L. The calculation is reliable, validated and the substance properties fall within the applicability domain of the QSAR.

Additional information
One QSAR is avaible to assess the chronic toxicty of the registered substance to fish.
The fish 32/33d-NOEC was predicted using the software ECOSAR v2.2 and the equation for phenols. The results indicate that the NOEC is 2.015 mg/L. The calculation is reliable, validated and the substance properties fall within the applicability domain of the QSAR.
