Key value for chemical safety assessment

Additional information

The EU RAR 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.
