Description of key information

Key value for chemical safety assessment

BCF (aquatic species):
50.8 dimensionless

Additional information

According to methods given in the TGD a BCFfish has been estimated, based on a measured logKowof 2.83 ± 0.05.

BCFfish= 50.8 (range 46.0 – 56.0)

Toxicokinetic data in rats indicate that the material undergoes considerable metabolism in mammals. It is therefore likely that the BCF calculated on the basis of the logKow overestimates the bioaccumulation potential.
