Description of key information
Calcium fluoride is a simple inorganic salt and (due to its low water solubility) will slowly dissociate in water at environmentally relevant pH to form calcium and fluoride ions. Subsequently, the Ca2+ ions will remain in the aqueous solution, whereas a (small) part of the F- ions will form HF due to the fact that the latter is a weak acid. This is the theoretical hydrolysis of the inorganic salt CaF2. The liberated ions will be indistinguishable from those naturally present in the environment and will be further transformed in water, sediment and soil to a variety of other calcium and fluorine-containing compounds.
Biodegradation is not a relevant concept for inorganic substances such as CaF2.
Additional information
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.
