Description of key information

Cyanuric acid (concantration: ca. 275 mg/L) was treated both with UV radiation and with UV-irradiated H2O2. After 30 minutes treatment the concentration of the the test item (cyanuric acid) that was treated with UV radiation and with UV-irradiated H2O2 was determined to be ca. 225 mg/L and ca. 275 mg/L, respectively. Since these concentrations do not differ strongly from the initial test item concentration, photodegradation of the test item is not considered.

Key value for chemical safety assessment
