Bioaccumulation factoropen allclose all
- Type:
- BCF
- Value:
- >= 3.2 - <= 6.8 dimensionless
- Basis:
- not specified
- Time of plateau:
- 2 wk
- Calculation basis:
- steady state
- Remarks on result:
- other: Conc.in environment / dose:0.05 mg/L
- Type:
- BCF
- Value:
- <= 23 dimensionless
- Basis:

- Remarks on result:
- other: Concentration of test substance in test fish was below the minimum limit of detection.
- Remarks:
- Conc.in environment / dose:0.5 mg/L
Applicant's summary and conclusion
- Conclusions:
- The experimentally derived BCF values indicate that the substance has a relatively low bioaccumaltaion potential and does not meet the bioaccumalation criteria according to Annex XIII of the Reach regulation.
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.
