Description of key information

Read-across from an activated Sludge, Respiration Inhibition study  with monosodium salt of cyanuric acid. 

Key value for chemical safety assessment

EC50 or LC50 for microorganisms:
5 773 mg/L

Additional information

Read-across:

1. Based on the experimental results obtained with the analogue monosodium salt of cyanuric acid (3h-NOEC = 2700 mg/L and 3h-EC50 > 4500 mg/L) and the molecular weights, the read-across approach is applied and the 3h-NOEC and 3h-EC50 for substance trisodium cyanurate are calculated to be 3464 mg/L and higher than 5773 mg/L, respectively.
