Description of key information

The key value selected is the BCF in fish of 1584 L/kg ww.

Key value for chemical safety assessment

BCF (aquatic species):
1 584 L/kg ww

Additional information

The available results were reviewed in the EU Risk Assessment Report for HHCB (2008). It was concluded that the key study was the one reported in Balk and Ford (1999), performed by Van Dijk (1996), resulting in BCF = 1584. The BCF from this laboratory study is higher than the BCFs obtained in other laboratory studies. The results obtained from field studies show a lower bioaccumulation. Thus the BCF of 1584 is a conservative value for the risk assessment.
