Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
Description of key information
Half-life for primary biodegradation in two freshwater lakes ranged from 20 - 28 days. Incubations were not carried out for sufficient time to quantify kinetics of mineralization. However, evolution of 14CO2 indicates the potential for complete mineralization of the substance by non-adapted surface water microorganisms.
Additional simulation testing in sediment is waived based on the substance being readily biodegradable.
Key value for chemical safety assessment
- Half-life in freshwater:
- 28 d
- at the temperature of:
- 293 K
Additional information
Half-life for primary biodegradation in two freshwater lakes ranged from 20 - 28 days, as corrected for degradation in killed control experiments. Incubations were not carried out for sufficient time to quantify kinetics of mineralization. However, evolution of 14CO2 indicates the potential for complete mineralization of the substance by non-adapted surface water microorganisms.
