EC number: 939-727-1 | CAS number: -
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species, other
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Calculation with a QSAR method (BCFWin)
- Justification for type of information:
- QSAR prediction: migrated from IUCLID 5.6
- Qualifier:
- according to guideline
- Guideline:
- other: QSAR estimation method referenced in ECHA guidance R.6 on QSARs and grouping of chemicals (2008)
- Principles of method if other than guideline:
- A QSAR method for estimating the bioconcentration factor of organic chemicals is supplied in BCFWIN program. The estimation methodology is based on QSAR estimation equation for Log Kow specific range (in case of non-ionic structure).

- BASIS INFORMATION
- Calculated logPow: 5.55
BASIS FOR CALCULATION OF BCF
- Estimation software: BCFWIN - Type:
- BCF
- Value:
- 91 L/kg
- Basis:
- whole body w.w.
- Validity criteria fulfilled:
- not applicable
- Remarks:
- Calculations
- Conclusions:
- The calculated BCF is 91 L/kg wet/wet using BCFWIN program
- Executive summary:
The bioconcentration factor was estimated by calculation with the QSAR BCFWIN equation developped for substances with a log Kow between 1.0 and 7.0:
log BCFfish= 0.6598 x log Kow − 0.333 + Sum (correction factors)
The calculated BCF is 91 L/kg wet/wet
Reference
Description of key information
The substance exhibits an estimated fish BCF of 91 L/kg, using the BCFWIN Program.
Key value for chemical safety assessment
- BCF (aquatic species):
- 91 L/kg ww
