Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
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.
Key value for chemical safety assessment
- Half-life in freshwater:
- 38 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 340 d
- at the temperature of:
- 25 °C
Additional information
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.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
