Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The half-lives of biodegradation of cresols in soil range between 0.6 d (m-cresol) and 1.6 d (o-cresol) in acidic sandy loam and between 0.5 d (p-cresol) and 11.3 d (m-cresol) in basic sandy silt loam. 

Key value for chemical safety assessment

Additional information

The degradation behaviour of o-, m- and p-cresol was investigated by Loehr et al. (1992) in two different soils. The first soil (acidic) was a sandy loam with an organic carbon content of 0.94%. The second soil (basic) 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. The test was conducted in darkness at 20 °C. The test compounds degraded with the following half-lives:



acidic soil – sandy loam

half-life [days]

basic soil – sandy silt loam

half-life [days]
