Description of key information

Read-across from a sediment-water chironomid toxicity test according to OECD Guideline 218 with the monosodium salt of cyanuric acid. 

Key value for chemical safety assessment

EC50 or LC50 for freshwater sediment:
1 146.57 mg/kg sediment dw
EC10, LC10 or NOEC for freshwater sediment:
1 146.57 mg/kg sediment dw

Additional information


1. Based on the experimental results obtained with the analogue monosodium salt of cyanuric acid, monohydrate (28 d-EC50 > 1000 mg/kg sediment dw ; 28 d- NOEC = 1000 mg/kg sediment dw) and the molecular weights, the read-across approach is applied and the 28 d-EC50 and 28 d-NOEC for substance trisodium cyanurate are calculated to be higher than 1146.57 mg/L and 1146.57 mg/L, respectively.
