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.

Additional information

The biodegradation of o-, m-, and p-cresol was investigated in numerous studies. It was shown that cresols are biodegradable under different test conditions. Using adapted and non-adapted activated sludge as inoculum, inherent and ready biodegradation of all cresol isomers could be shown. Biodegradation of m-cresol and p-cresol also could be observed under anaerobic conditions using sludges from STPs as well as different sediment types as inoculum. Biodegradation of o-cresol under anaerobic conditions could not be observed. Tests in marine water showed degradation of p-cresol. Studies on biodegradation in sediment and soil showed that o-, m- and p-cresol can be biodegraded in both compartments.


Due to their ready biodegradability cresols are not expected to persist in the environment.
