Description of key information
No studies have been conducted on the reaction mass of CaF2, CaSO4 and CaCO3. Instead information is available on the different constituents.
Studies show that calcium sulfate and calcium carbonate, ubiquitous in the environment and essential to living organims, are not toxic to sewage sludge microorganisms.
In the EU RAR 2001 review, the long-term NOEC-values for micro-organisms range from 7.1 to 510 mg/L. Only the test with 3 h exposure of activated sludge was performed according to international accepted guidelines, yieling an EC10 of 510 mg/L F-. In this test the given EC10-value for respiration inhibition is considered to be an equivalent for a NOEC. Using the molecular weight, this results in a NOEC of 1047.51 mg/L CaF2.
On the basis of the available effect levels for CaF2, the values for the reaction mass can be concluded: 2095 mg/L RM. These values are 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.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 2 095 mg/L
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.
