Reference
Endpoint:
bioaccumulation in aquatic species, other
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Study period:
April 2018
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
results derived from a (Q)SAR model, with limited documentation / justification
Qualifier:
no guideline followed
Principles of method if other than guideline:
A bioconcentration factor (BCF) was estimated in BCFWIN v2.17 in EpiSuite™. The model uses a traditional regression method based on Log Kow and the Arnot-Gobas method to provide an estimate for BCF.
GLP compliance:
no
Key result
Type:
BCF
Value:
3.162
Basis:
other: (Q)SAR prediction
Remarks on result:
other: Log BCF = 0.500
Validity criteria fulfilled:
not applicable
Conclusions:
A bioconcentration factor (BCF) of 3.162 (Log BCF = 0.500) was predicted in the BCFWIN v2.17 model for 2-ethylbutyric acid.

Description of key information

The BCFWIN v2.17 model in Epi Suite obtained a bioconcentration factor (BCF) prediction for 2-ethylbutyric acid of 3.162 (Log BCF = 0.500).

Key value for chemical safety assessment

BCF (aquatic species):
3.162 dimensionless
