Link to relevant study record(s)

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.
