Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests:  

Chlorocresol was estimated to be 50% biodegradable in water in 38 days (half-life) indicating that chlorocresol is readily biodegradable in water since the half life is less than the threshold of 40 days (to qualify the chemical as persistent).

Biodegradation in water and sediment: simulation tests:

Based on level III fugacity model the half life period of chlorocresol was estimated

Half life period of chlorocresol in water was observed to be 38 days while in sediment it is 340 days. Based on these half life values of it is concluded that chlorocresol is readily biodegradable in water where as it is non biodegradable in sediment. However, since there is no diffusion of the substance in the sediment as evident from the reported data (1% in sediment) and hence persistence in the sediment compartment is not likely to be critical.

Biodegradation in soil:

Half life period of chlorocresol in Soil was observed to be 75 days which does noy exceeds the threshhold of >120 days. Based on these half life values it is concluded that chlorocresol is readily biodegradable (not persistent) in Soil
