Biodegradation in water and sediment: simulation tests

Description of key information
In accordance with column 2 of Annex IX, this study was waived as benzyl propionate is readily biodegradable.
Key value for chemical safety assessment
- Half-life in freshwater:
- 15 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 140 d
- at the temperature of:
- 25 °C
Additional information
Based on the Level III Fugacity Model, the half life period of the substance benzyl propionate was estimated. The half life period of benzyl propionate in water is 15 days , therfore it is considered that the substance will qualify as not persistent as the half life does not exceed the threshold of 60 days. So, it can be confirmed that the substance is readily biodegradable in water medium whereas in sediment the half life is 140 days and based on this value, it can be inferred that the substance is persistent in sediment medium and is not readily biodegradable. However, it can be observed that benzyl propionate does not diffuse in the sediment medium since it's percentage in the sediment medium is reported to be 0% and hence persistence in the sediment compartment is not likely to be critical.
