Additional information

Limited data are available for the substance calcium fluoride due to its low water solubility. Testing was preformed using more water-soluble fluoride compounds such as sodium fluoride. The PNEC derivation presented is based on this extensive dataset. The aquatic PNEC was derived from a NOEC of 8.9 mg/L (F-) in long-term Daphnia studies. Based on fluoride concentration, this is equivalent to 18.2 mg/L calcium fluoride, a concentration which exceeds the limit of solubility of this susbtance. It is therefore concluded that calcium fluoride will not have any adverse effects due to its low water solubility.

Conclusion on classification

No classification is proposed. It can be concluded that calcium fluoride will not have any adverse effects in the environment due to its low water solubility.
