Description of key information

The experimentally determined Koc values for o-cresol are: 22 for a clay loam, 50 for coal and 56 for river sediment.
As a worst-case assumption, the lowest experimentally determined Koc value of 22 is taken into account for further assessment.

Key value for chemical safety assessment

Koc at 20 °C:
22

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 22 was determined.

In an experiment the sorption properties of o-cresol in sediments using the batch equilibrium method was determined. A Koc of 50 and 56 was found for coal and river sediment, respectively.

The Koc values suggest a low potential for adsorption for o-cresol in soil and sediment.
