Description of key information

p-Cresol degraded with half-live times of <1 d for the sandy loam (basic soil) and 0.5 d for the sandy silt loam (acidic soil).

Key value for chemical safety assessment

Half-life in soil:
0.5 d
at the temperature of:
20 °C

Additional information

The substance is readily biodegradable and no biodegradation simulation test has to be performed for soil according to REACH Annex IX column 2.

The degradation behaviour of p-cresol was investigated in two different soils. The first soil (acidic) was a sandy loam with an organic carbon content of 0.94%. The second was a sandy silt loam with an organic carbon content of 3.25%. The loadings of the soils and the degradation were monitored by an HPLC method. Maintained in the dark at 20°C, p-cresol degraded with half-live times of < 1d for the sandy loam and 0.5 d for the sandy silt loam.
