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 investiated over a period of 22 weeks. At higher concentrations sodium fluoride, potassium fluoride and the sodium salt of fluoroacetic acid reduced 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 potasium fluoride (Vogel & Ottow, 1992).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
