Reference
Endpoint:
adsorption / desorption: screening
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method)
GLP compliance:
no
Type of method:
batch equilibrium method
Media:
soil
Radiolabelling:
no
Test temperature:
20 +/-1 °C
Analytical monitoring:
yes
Details on test conditions:
Soil: Brookston clay loam soil (type Argiaquoll, fine, loamy, mixed, mesic), collected from top 15 cm air-dried, 5.10% organic matter, pH 5.7, soil/solution ratio 1:10, TS concentrations 5, 10, 20, 30, 50 mg/l, deoxygenated by purging with a mixture of N2 and H2 (9:1 v/v)
Type:
Koc
Value:
34.58
Transformation products:
not measured
Conclusions:
The Koc of m-cresol was determined with a batch equilibrium method, similar to OECD Guideline 106. The low koc of 35 suggests a low potential for adsorption in soil.
Executive summary:

The Koc of m-cresol was determined with a batch equilibrium method, similar to OECD Guideline 106. The low koc of 35 suggests a low potential for adsorption in clay loam.

Description of key information

The experimentally determined Koc value  for m-cresol is 35 for a clay loam.

Key value for chemical safety assessment

Koc at 20 °C:
35

Additional information

The distribution between the organic phase of soil solids and water was determined in batch equilibrium experiments similar to the OECD guideline 106. For a clay loam soil a Koc of 35 was determined.
