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.
Short-term toxicity to fish has been evaluated for calcium sulfate and calcium carbonate. As expected, no hazards have been identified for both constituents.
As no reliable studies are available for calcium fluoride, fish acute toxicity data published on NaF have been used. The chosen key value was the lowest reported LC50 among all reliable evaluated studies. The reported value by Janssen et al. (1989) on Oncorhynchus mykiss, 96h exposure (EU RAR and ICD) was 51 mg F-/ L, which translates to 104.7 mg CaF2/L. Note that this value is above water solubility of CaF2 being 15 mg/L at 25°C. No reliable information is available on marine water fish.
On the basis of the available LC50 for CaF2, the LC50 value for the reaction mass can be concluded: 209.4 mg RM/L. 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.
The water solubility of calcium fluoride is lower (15 mg/L) than the LC50 value (209.4 mg/L based on fluoride equivalent for the reaction mass), no toxicity of the reaction mass of calcium fluoride, calcium sulfate and calcium carbonate is expected on aquatic fish at short term.
