Administrative data
- Endpoint:
- other distribution data
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- not reported.
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The model is scientifically validated by the publisher (U.S. EPA) and is appropriate to the substance type (organics). The model is relevant for the regulatory purpose and isconsidered to adequately fulfil the requirement.
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6
