Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance exhibits an estimated fish BCF of 855.7 L/kg (geometric mean of three QSAR results)

Key value for chemical safety assessment

BCF (aquatic species):
855.7 L/kg ww

Additional information

Three QSAR estimations were performed :

- Regression-based estimate, BCFBAF v3.01

- Arnot-Gobas lower trophic level (including biotransformation), BCFBAF v3.01

- TGD (2003) part. II, eq. (74)

The output of calculations are shown here below:

-Regression-based estimate (BCF-BAF v3.01): BCF = 407.1 L/kg

-Arnot-Gobas lower trophic level (BCF-BAF v3.01): BCF = 1248.0L/kg

-TGD (2003): BCF = 1233.1 L/kg

For the purposes of defining a key value for chemical safety assessment, it is proposed to give an equivalent weight for each BCF estimation and to use the geometric mean to determine a representative BCF value:

-BCFgeom.mean = 855.7 L/kg ww
