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
