Description of key information
The main mode of urea degradation is enzymatic mineralization.
Key value for chemical safety assessment
Additional information
The main mode of urea degradation is enzymatic mineralization. In soil and water, urea is expected to biodegrade fairly rapidly to ammonia and bicarbonate if the temperature is not too low. The main factors affecting the rates of nitrogen metabolism are the initial concentration of the ureolytic bacteria, the physical state of the nitrifying micro-organisms and the concentration of toxic organics.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
