Administrative data

Endpoint:
adsorption / desorption
Remarks:
adsorption
Type of information:
(Q)SAR
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Validated QSAR model. These models have no universally accepted definition of model domain, but since the substance is outside the Kow range of the training set, the results should be taken with caution. The definite values may not be fully reliable, but indicate a high adsorption potential, which can be taken into account for further assessments. Therefore, it can be assumed that the adsorption potential of the substance is high.
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6
