Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In a BCF study from 1978, published in 1992 (MITI), bioaccumulation factors ranging from 260 to 2150 have been determined for DPPD. Furthermore, there QSAR predictions have been performed to further assess the potential for bioaccumulation of the registration item. The BCF base-line model (v.02.09 - July, 2017; available in OASIS Catalogic v5.12.1) predicted a log BCF (log(L/kg) wet weight) 2 39 ± 0.187, corresponding to a BCF of 245.5 ± 1.5 for DPPD. Additionally, the BCFBAF Program (v3.01, part of EPI Suite v4.10) estimates the Log BCF = 2.332 (corresponding to BCF = 214.9 L/kg wet-wt).
Considering the available information in a weight-of-evidence approach, the screeining criterion for B (BCF > 2000) appears not fulfilled.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
