Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Low bioconcentration factors have been measured in aquatic species. On freshwater fish, BCF has been measured and documented on rainbow trout (40) and bluegill sunfish (30)

Key value for chemical safety assessment

BCF (aquatic species):
40 dimensionless

Additional information

Several experimental determinations of BCF have been carried out on freshwater fish species. Of them 2 studies are reported in substantiated enough in their reporting to be used in this assessment. Brosier et al. reported a study in 1972 on rainbow trout (Oncorhynchus mykiss). BCF was calculated according to the kinetic model (ratio of uptake and clearance kinetics) as being 40 (dimensionless). In a study on bluegill sunfish (Lepomis macrochirus) Barrows et al. (1980) register a BCF of 30. In both studies, a rapid clearance is observed (half-life < 1 day). Other data exist on fish or algae but too few experimental information is available to use these studies in the present assessment.
