Description of key information

One published study of the effects of fluoride on Eisenia fetida is available.

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for soil macroorganisms:
1 200 mg/kg soil dw

Additional information

The toxicity of various fluoride compounds to Eisenia fetida was investigated over a period of 22 weeks. At higher concentrations sodium fluoride, potassium fluoride and the sodium salt of fluoroacetic acid reduced growth significantly. Calcium fluoride had no effect. The rate of maturity of the earthworms was also significantly reduced when sodium fluoride and potassium fluoride was used. The number of hatchlings was reduced in the presence of sodium fluoride, while the number of cocoons was reduced in the presence of a low concentration of sodium fluoride and potassium fluoride (Vogel & Ottow, 1992).
