Description of key information

The 48-h EC50 of 22.8 mg/L in Daphnia magna, which corresponds to a 48-h EC50 of 12.2 mg/L based on fluoride. The 48-h EC50 of 12.2 mg F/L is used in the assessment.

Key value for chemical safety assessment

Additional information

One GLP-compliant OECD 202 guideline study is available for acute toxicity in Daphnia magna. The concentrations were analytically verified. Immobilisation was observed and a 48-EC50 was 22.8 mg/L, based on nominal concentrations (Solvay Pharmaceuticals, 1999).
