Description of key information
No studies have been conducted on the reaction mass of CaF2, CaSO4 and CaCO3. Instead information is available on the 3 different constituents.
No short-term toxicity has been observed for CaSO4 and CaCO3.
No studies are available for calcium fluoride. Available studies on NaF were used as read-across source in a weight-of-evidence approach. The chosen key value for freshwater invertebrated was the lowest reported EC50 among all the evaluated studies reported by Pearcy et al. 2015 on Hyalella azteca after 96h exposure to NaF. The EC50 was 24.8 mg/L F- which converts in 50.94 mg/L CaF2. Effects to marine invertebrates (Mysidopsis bahia) have been reported with an EC50 of 21.6 mg/L CaF2 (EU RAR).
On the basis of the available EC50 for CaF2, the EC50 value for the reaction mass can be concluded: 101.88 mg RM/L for freshwater invertebrates and 43.2 mg/L for marine invertebrates. This value is calculated by taking into account that the reaction mass contains only 50% of CaF2 (ca. 47.5 w/w % CaF2) and that the additional of Ca2+ through CaSO4 and CaCO3 would even further reduce the toxicity of CaF2 as free F- will be complexed.

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.
