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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 203-450-8 | CAS number: 106-99-0
Bioaccumulation: aquatic / sediment

Description of key information
A calculated BCF of 9.8 was determined for butadiene on the basis of a log Kow of 1.99.
Key value for chemical safety assessment
- BCF (aquatic species):
- 9.8 dimensionless
Additional information
The bioaccumulation in aquatic species study has not been conducted as 1,3 -butadiene has a low potential for bioaccumulation, with a log octanol water partition coefficient less than 3. On the basis of its log Kow of 1.99, a BCF of 9.8 has been calculated. As 1,3 -butadiene is a gas that will rapidly volatilize from the aquatic environment, direct and indirect exposure in the aquatic environment is unlikely.
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.
