Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- (Q)SAR
- Adequacy of study:
- other information
- 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:
- Documentation about the justification is provided in attachment (See Supporting information). The reliability assessment of the prediction is shown in the attached document as well (QPRF). QSAR model reporting format is shown in the QMRF file attached.
