Description of key information

No significant biodegradation in water and sediment is expected.

Key value for chemical safety assessment

Additional information

Considering the molecular structure and intrinsic properties of UMA 121 constituents as well as the low biodegradation obtained in the available study on inherent biodegradability, no biodegradation is expected in water and sediment. The substance is therefore assumed to be persistent and no simulation tests are proposed.
