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

EC50/LC50 for freshwater invertebrates:
1 510 mg/L
EC50/LC50 for marine water invertebrates:
6 705.3 mg/L

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)).
