Bioaccumulation factor
- Type:
- BCF
- Value:
- 606.5 L/kg
- Basis:
- whole body w.w.
- Calculation basis:
- steady state
- Remarks on result:
- other: Estimate using BCFBAF v. 3.0
Any other information on results incl. tables
--------------------------------- BCFBAF v3.00 --------------------------------
Log Kow (experimental): not available from database Log Kow used by BCF estimates: 2.78
Equation Used to Make BCF estimate: Log BCF = - 0.49 log Kow + 7.554 + Correction
Correction(s): Value No Applicable Correction Factors
Applicant's summary and conclusion
- Conclusions:
- regression-based method.
- Executive summary:
BCF values vary from 88.29 L/kg (based on Arnot-Gobas method) to 1686 L/kg based on the BCFBAF v3.00 regression-based method. These estimates do not consider hydrolysis or biotranformation of the substance, both of which are expected to be high. Actual testing of this substance for BCF is not feasible given the rapid hydrolysis and very low water solubility. The BCF of phenol (the primary hydrolysis product) is 17.5 L/Kg (EU Phenol RAR 2006) and the BCF of isodecanol is 131 L/kg (EPISuite 4.0).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
