Description of key information

Isocyanuric acid (CAS no.: 108-80-5) was tested for toxicity to fish in a prolonged 14 day test. The 14-day maximum no-observable effect concentration (NOEC), 7-day median lethal concentration (LC50) and the 14-day median lethal concentration (LC50) were determined to be > 100.0 mg/L (nominal concentration).

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater fish:
100 mg/L

Additional information

In the study (97-0708-FGO_en) isocyanuric acid (CAS no.: 108-80-5) was tested for toxicity to fish in a prolonged 14 day test according to OECD guideline 204. The 14-day maximum no-observable effect concentration (NOEC), 7-day median lethal concentration (LC50) and the 14-day median lethal concentration (LC50) were determined to be > 100.0 mg/L (nominal concentration).
