Endpoint:
adsorption / desorption, 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:
PCKOCWIN v1.66 (or KOCWIN) is a model in Epi Suite™ that uses a traditional method based on Log Kow and the Sabljic molecular connectivity method to predict the soil adsorption coefficient (Koc) of organic substances in soil and sediment.

Value:
0.85 dimensionless
Validity criteria fulfilled:
not applicable
Conclusions:
The soil adsorption coefficient of 2-ethylbutyric acid was predicted to be Koc = 7.074 (Log Koc = 0.850) by KOCWIN v1.66 in Epi Suite™.
