Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 bioconcentration factor in fish was determined using the ASTM E-35.21 guideline.  The BCF was 35.

Key value for chemical safety assessment

BCF (aquatic species):
35 dimensionless

Additional information

In cases where no data were available on the target substance, Benzene, C15-16-alkyl derivs., data were read-across from a structurally related material (the test substance).

The study examined the bioaccumulation of a read-across source substance for Benzene, C15-16-alkyl derivs. in fish. A total of 150 bluegill sunfish were exposed to 0.092 mg/L of the test substance for 96 hours in a flow through apparatus. Three fish were sampled at several points during the study and analyzed for the test substance in the tissues. A steady state concentration was reached at 48 hours and additional fish were sampled during a depuration period. The resultant bioconcentration factor was 35.
