Description of key information

3 -oxoglutaric acid is 50% biodegradable in water and sediment in 8.7 days and in 78 days respectively. This values indicates that 3 -oxoglutaric acid is readily biodegradable in water and not readily biodegradable in sediment according to the EPA criteria of >= 60 days (to qualify the chemical as persistent).

Key value for chemical safety assessment

Half-life in freshwater:
8.7 d
Half-life in freshwater sediment:
78 d

Additional information

3 -oxoglutaric acid is 50% biodegradable in water and sediment in 8.7 days and in 78 days respectively. This values indicates that 3 -oxoglutaric acid is readily biodegradable in water and not readily biodegradable in sediment according to the EPA criteria of >= 60 days (to qualify the chemical as persistent).

Hence, it can be concluded that the substance 3 -oxoglutaric acid is not persistent in water but persistent in sediment sediment.
