Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
toxicity to aquatic algae and cyanobacteria
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
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
Danish QSAR database's EPI ECOSAR
2. MODEL (incl. version number)
v1.11
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
C(C)(C)(C)C1C(=O)C=C(C(C)(C)C)C(=O)C=1
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
[Explain how the model fulfils the OECD principles for (Q)SAR model validation. Consider attaching the QMRF or providing a link]
- Defined endpoint: Green alage 96 hour growth inhibition
Qualifier:
no guideline available
Principles of method if other than guideline:
- Software tool(s) used including version: Danish QSAR database's EPI ECOSAR
- Model(s) used: 1.11
- Model description: see field 'Justification for non-standard information'
- Justification of QSAR prediction: see field 'Justification for type of information', 'Attached justification' and/or 'Cross-reference'
GLP compliance:
not specified
Specific details on test material used for the study:
