Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
No data are available for calcium fluoride. Available studies on fluoride were used as read-across source. Effective concentrations were recalculated taking in account the different molecular weight of the source and target substance.
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, yielind 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.
The NOEC-values for other micro-organisms are only used as supportive information.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 047.51 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.
