Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Bioaccumulation: aquatic / sediment:
From BCFBAF Program (v3.00) model of EPI suite the estimated bio concentration factor (BCF) for 1H-dibenzo[a,d][7]annulen-1-one is 85.28 L/kg wet-wt which does not exceed the bioconcentration threshold of 2000.Thus it is concluded that 1H-dibenzo[a,d][7]annulen-1-one is not expected to bio accumulate in the food chain.
Additional information
Bioaccumulation: aquatic / sediment:
Four different validated predicted models estimate the bioaccumulation in aquatic endpoint for target chemical 1H-dibenzo[a,d][7]annulen-1-one (Cas no. 2222-33-5) which are summarized as followed:
First data from BCFBAF (v3.00) model of EPI suite estimated bio concentration factor (BCF) for 1H-dibenzo[a,d][7]annulen-1-one as 85.28 L/kg wet-wt which does not exceed the bioconcentration threshold of 2000.Thus it is concluded that 1H-dibenzo[a,d][7]annulen-1-one is not expected to bio accumulate in the food chain.
Another prediction done by PBT profiler which indicate the Bioaccumulation factor (BCF) was predicted to be 85 L/kg wet-wt at 25 deg.C. Based on the BCF concentration it is concluded that the test chemical 1H-dibenzo[a,d][7]annulen-1-one is non bioaccumulative in nature as it does not exceed the BCF criteria of 2000.
Also Scifinder database suggest the Bioconcentration factor (BCF) for target chemical 1H-dibenzo[a,d][7]annulen-1-one was predicted to be 261 at pH 1-10 and temperature 25 deg.C.
And Chemspider - ACD/PhysChem Suite predicted model indicate Bioconcentration factor (BCF) for target chemical 1H-dibenzo[a,d][7]annulen-1-one was predicted to be 110.21 at pH 5.5 and 7.4 at temperature 25 deg.C.
All predicted values for bioaccumulation is in the range of 85-261(L/kg or dimensionless) conclude the target chemical 1H-dibenzo[a,d][7]annulen-1-one (Cas no. 2222-33-5) is non bioaccumulative in aquatic environment as it does not exceed the BCF criteria of 2000 as per the CLP regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
