Description of key information
Read-across from two 48h static toxicity studies were performed on daphnia magna. A study has also been performed with the marine aquatic invertebrate mysid shrimp.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates

Additional information
Read-across:
1 and 2. Based on the experimental results obtained in 2 tests with the analogue cyanuric acid (48 h-LC50 > 1000 mg/L) and the molecular weights, the read-across approach is applied and the LC50 for substance trisodium cyanurate is calculated to be higher than 1510 mg/L (in Daphnia magna).
3. Based on the experimental results obtained with the analogue cyanuric acid (96 h-LC50=4438 mg/L) and the molecular weights, the read-across approach is applied and the LC50 for substance trisodium cyanurate is calculated to be 6705.3 mg/L (in Mysidopsis bahia (new name: Americamysis bahia)).
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.
