Description of key information

In a reliable GLP- and guideline-conform study of cesium fluoroaluminate according to OECD 202 (2004), the 48h-EC50 for the immobilisation of daphnia magna amounts to 41.30 mg cesium fluoroaluminate/L (based on measured Cs concentrations) (Brüggemann, 2018). Thus, cesium fluoroaluminate seems to have some potential for toxicity to aquatic invertebrates.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
50 mg/L
