Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
323.5 l/kg wet-wt (BCF regression-based method)
Key value for chemical safety assessment
- BCF (aquatic species):
- 323.5 L/kg ww
Additional information
The bioaccumulation of the substance was calculated by the use of BCFBAF program which estimates the BCF (Bioconcentration Factor) of an organic compound using the compound's log octanol-water partition coefficient (Kow).
Arnot-Gobas model was also used in order to estimate the steady-state bioconcentration factor (BCF; l/kg) and bioaccumulation factor (BAF;l/kg) values for non-ionic organic chemicals in three general trophic levels of fish. For the calculation the compound's log octanol-water partition coefficient (Kow) and the normalized whole-body metabolic biotransformation rate constant (kM, N; /day) were used.
The LogKow used for the calculation of BCF was 13.15 (calculated by KOWWIN v.1.68).
The BCF of the substance is 0.8949 l/kg wet-wt while the BAF is 1.358 l/kg (upper trophic, Arnot-Gobas).
The BCF of the substance calculated is 323.5 l/kg wet-wt, while the LogBCF is 2.510 (BCF regression-based method).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
