Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Accepted calculation method
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Quantative Structure Activity Modeling Program, EpiSuite version 3.20; BCFWin version 2.17
- GLP compliance:
- no
- Key result
- Type:
- BCF
- Value:
- >= 160 - <= 263 dimensionless
- Remarks on result:
- other: The substance is not expected to bioaccumulate in the food chain because it does not exceed the US EPA BCF criteria.
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The substance is not expected to bioaccumulate in the food chain because it does not exceed the US EPA BCF criteria.
- Executive summary:
The structure of the substance was modeled for Bioaccumulation potential using BCFWIN version 2.17 of the US EPA EPISuite verion 3.20.
Using two experimentally derived octanol/water partition coefficient, the BCF was calculated to be 160 -263 (log 2.2 - 2.4).
The substance is not expected to bioaccumulate in the food chain because it does not exceed the US EPA BCF criteria.

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.
