Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In general, chemicals that have the potential to bioconcentrate also have the potential to bioaccumulate. Since a bioconcentration factor (BCF) in fish can be readily measured in the laboratory and bioaccumulation is much more complicated to determine, the BCF is frequently used to predict the importance of bioaccumulation. The estimated bioconcentration factor (BCF) for Acetic acid, difluoro-, 3.2, does not exceed the EPA bioconcentration criteria.

Thus, the model estimates that Acetic acid, difluoro- is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
