Description of key information

The 30-min EC50 and 3-h EC50 were both >75 mg/L in activated sludge based on respiration inhibition, which corresponds to a 30-min EC50 and 3-h EC50 of >40 mg/L based on fluoride. The 3-h EC50 of >40 mg F/L is used in the assessment.

Key value for chemical safety assessment

Additional information

One GLP-compliant OECD 209 guideline study is available for the toxicity to microorganisms. The 3-h EC50 and 3-h NOEC were both >75 mg/L in activated sludge (Solvay Pharmaceuticals, 2010c).
