Description of key information

No studies are available for calcium fluoride. However, the EU RAR reviews and summarises the available data on the toxicity of sodium fluoride to freshwater and marine algae species.

Key value for chemical safety assessment

EC50 for freshwater algae:
43 mg/L
EC50 for marine water algae:
80 mg/L
EC10 or NOEC for freshwater algae:
50 mg/L
EC10 or NOEC for marine water algae:
50 mg/L

Additional information

No studies are available for calcium fluoride. However, the EU RAR and ICD reviews and summarises the available data on the toxicity of sodium fluoride to freshwater and marine algae species. The EC50 values for freshwater algae are reported to range from 43 to 122 mg/L (as fluoride ion, F-). For marine algae the EC50 was 81 mg/L in a single study with Skeletonema costatum. NOEC values of 50 -249 mg/L and 50 -200 mg/L are reported for freshwater and marine algae, respectively.
