Description of key information
Degradation by photolytic processes can be excluded.
Key value for chemical safety assessment
Additional information
There is no evidence for photodegradation of ammonium sulfate. However, ammonium sulfate may be formed in atmospheric aerosols (occurrence predominantly in the fraction < 2.5 µm) from reaction between ammonia and sulfuric acid (from SO2 emissions). SO2 concentrations control the ammonium sulfate formation (Scott and Cattell 1979; Gmur, Evans and Cunningham 1983).

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.
