Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is readily biodegradable
- Endpoint:
- biodegradation in water: sediment simulation testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is readily biodegradable

Description of key information
No surface water or sediment degradation studies were conducted, so first order rate constants and half-lives for biodegradation in surface water and sediment were derived based on ready biodegradability results, in accordance with ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.16.
Key value for chemical safety assessment
- Half-life in freshwater:
- 15 d
- at the temperature of:
- 12 °C
- Half-life in marine water:
- 15 d
- at the temperature of:
- 12 °C
- Half-life in freshwater sediment:
- 300 d
- at the temperature of:
- 12 °C
- Half-life in marine water sediment:
- 300 d
- at the temperature of:
- 12 °C
Additional information
As the substance is readily biodegradable, default half-lives for freshwater and sediment were concluded in accordance with ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.16.
