Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Principles of method if other than guideline:
Formerly called BCFWIN, the BCFBAF program estimates fish bioconcentration factor (BCF) and its logarithm using two different methods. The first is the traditional regression based on log KOW plus any applicable correction factors. The second is the Arnot-Gobas method, which calculates BCF from mechanistic first principles. BCFBAF also incorporates prediction of apparent metabolism half-life in fish, and estimates BCF and BAF for three trophic levels. The program is based on methodologies developed by Arnot-Gobas et al. (2003, 2006, 2008). A 5% lipid normalisation has been used for the Arnot-Gobas method BCF values, as recommended in OECD TG 305.

Applicant's summary and conclusion

Conclusions:
The predicted BCF values of the constituents of these streams range from 3.2 to 12882.5 L/kg ww. Of the 48 constituents, 10 have a BCF value of greater than 2000 L/kg ww. Details of the constituents and how their BCF predictions relate to their bioaccumulation assessment are found in the PBT report attached to Section 13 (see cross-reference).
Executive summary:

The bioconcentration factor (BCF) values of the measured constituents (at equal or above 0.1% w/w) of this category has been predicted using the EPISUITE v4.11 BCFBAF (2017) model, which uses methodology descrived by Arnot-Gobas et al. (2003, 2006, 2008). The predicted BCF values of the constituents of these streams range from 3.2  to 12882.5 L/kg ww. Of the 48 constituents, 10 have a BCF value of greater than 2000 L/kg ww
