Description of key information

LogBCF = 0.55, BCF = 4 (CAESAR model)
LogBCF = 2.62, BCF = 414.2 (BCFBAF model)

Key value for chemical safety assessment

BCF (aquatic species):

Additional information

The BCF experimental value could not be selected, as the study was not available for evaluation.

Two different bioconcentration in fish (BCF) QSAR models were used to give a prediction for the LogBCF. The key BCF should be selected from CAESAR, as it is taken to be the generally more reliable model (see comparison Zhao, 2008) and a QMRF is available. Use of BCFBAF model for this substance presents a series of issues listed in the endpoint; however, it provides the most conservative result (worst case scenario) and it was considered for further assessments.
