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):
414

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.
