Description of key information

BCF in fish estimated by QSAR: 70.8  L/kg wet weight.

Key value for chemical safety assessment

BCF (aquatic species):
70.8 L/kg ww

Additional information

The bioaccumulation of the substance was assessed by using a validated QSAR model. No definite measured logPow is available for the substance (result >8.63). The BCF is 70.8 L/kg ww (based on logPow 8.63).

As the BCF is less than 500 the substance is not considered to significantly bioaccumulate in aquatic species.

The large molecular size (Dmax > 34 Angstroms) of the test substance also support its low bioaccumulation potential. Molecules of this size are generally considered to have low bioaccumulation potential due to their reduced uptake and low membrane permeability (Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment).
