Description of key information

Long-term earthworm NOEC values for sodium and potassium fluoride cited in the EC RAR for HF (2001) correspond to NOEC values of 543 and 245 mgF-/kg soil respectively.

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for soil macroorganisms:
326 mg/kg soil dw

Additional information

A 22-week NOEC value for earthworms of 326 mg LiPF6/kg soil is calculated from the reported NOEC for potassium fluoride (the result indicating the lower fluoride NOEC).
