Additional information
Short-term aquatic toxicity data for three trophic levels (fish, invertebrates and alga) are available for cesium potassium fluoroaluminate. The tests were conducted under GLP and followed OECD TG 201, 202 and 203, respectively. Algae were most sensitive with an ErC50 (72h) of 13.5 mg/L. The EC50 (48h) in Daphnia was 60 mg/L, the LC50 (96h) in fish was >120 mg/L.
The effect of the test item on the respiration of activated sewage sludge was assessed in a valid GLP study performed according to OECD TG 209. The EC50 value observed after 30 minutes and 3 hours exposure was greater than 100 mg/L.
Reliable studies on chronic toxicity of cesium potassium fluoroaluminate to the aquatic environment are available for three trophic levels: algae, invertebrates and fish.
- In the study of growth inhibition of the algae speciesPseudokirchneriella subcapitata performed according to OECD TG 201, a 72 -h NOErC of 2.3 mg/L was observed.
- A NOEC of 1.0 mg/L was observed for cesium potassium fluoroaluminate in a 21-day reproduction study with Daphnia magna according to OECD TG 211.
- A GLP-compliant short-term fish test on embryo and sac-fry stages was conducted according to OECD 212 with Gobiocypris rarus under semi-static conditions as part of a new chemical substance notification in China.
Based on nominal concentrations, the 8d-LC10 was 15.4 mg/L. According to the ECHA guidance on information requirements and chemical safety assessment - Chapter R.7b (ECHA, version 4.0, June 2017), the short
-term fish test on embryo and sac-fry stages is considered as a chronic test because the sensitive life-stages (juveniles, eggs, larvae) are exposed.
No information on sediment toxicity and terrestrial toxicity is available.
Conclusion on classification
For inorganic compounds, biotic degradation in the environment is an irrelevant process but abiotic dissociation and subsequent interactions occur instead. Nonetheless, for classification purposes, inorganic substances are to be considered as non-rapidly degradable.
Short-term toxicity EC/LC50 values of cesium potassium fluoroaluminate for 3 trophic levels are situated between 13.5 and >120 mg/L. In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (a), classification for acute aquatic hazard is not required for cesium potassium fluoroaluminate as all EC50/LC50 values are above the classification criterion of 1 mg/L.
Long-term toxicity data are available for three trophic levels and the criticial effect values range from 1.0 mg/L to 15.4 mg/L. In accordance with Regulation (EC) No 1272/2008, Table 4.1.0 (b) (i), cesium potassium fluoroaluminate is to be classified as hazardous to the aquatic environment category chronic 2; H411 (Toxic to aquatic life with long lasting effects) since the chronic NOEC value for daphnia is equal to the classification criterion of 1.0 mg/L.
