Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation in water:-
The half-life period of 3'-chloropropiophenone in water is 38 d and based on this value it can concluded that the substance is not persistent in water medium since the half-life is less than the threshold of 60 days (to qualify the chemical as persistent). Also the diffusion percentage of 3'-chloropropiophenone in water medium is 22%. This coupled with the dilution of water shall result in ready biodegradability of the chemical.

Biodegradation in water and sediment:
Half life period of 3'-chloropropiophenone in water is observed to be 38 d (912 h) while in sediment it is 340 d (8160 h).Based on these half life values of 3'-chloropropiophenone, it is concluded that the chemical 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 (0% in sediment) and hence persistence in the sediment compartment is not likely to be critical.

Biodegradation in soil:
Based on the Level III Fugacity Model the half life period of the 3'-chloropropiophenone was estimated. As per the values it was observed that in general 3'-chloropropiophenone persistence time is 1800 hr. The half life period of 3'-chloropropiophenonein soil is 1800 hrs and based on this value it is indicated that the chemical is persistent in soil medium.
