Description of key information

No studies are available for calcium fluoride, however a number of (largely non-guideline) published studies with sodium fluoride.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
8.9 mg/L

Additional information

No studies are available for calcium fluoride, however a number of (largely non-guideline) published studies with sodium fluoride are reviewed in the EU RAR and ICD. The EU RAR summarises the effects of two reproductive studies of sodium fluoride on Daphnia magna. The two studies report NOEC values of 3.7 and 14.1 mg/L, with an arithmetic mean of 8.9 mg/L. The ICD reports additional EC50 values in the range of 10 - 48 mg/L.
