Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A measured BCF is not available for any streams in this category but as the log Kow of some category members is >3, the bioaccumulation endpoint cannot be waived.Non-polar substances have been shown to have a linear relationship between log Kow and BCF in the log Kow range 1 to 6. Several QSAR have been developed that calculate the BCF of non-polar, hydrophobic compounds on the basis of their log Kow (e.g. Veith et al, 1979 and USEPA, 2008). The method of Veith et al (1979) was used to calculate the BCF for representative substances of the streams since most of the substances fall within the applicability domain of the model.

The calculated BCF for representative components of the streams in this category are in the range 25.9-235.6 l/kg.

The mean of the BCF for the category is 150.1 l/kg and this has been used to complete the 'key value for chemical safety assessment'.
