Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Fluoride accumulates in aquatic organisms predominantly in the exoskeleton of crustacea and in the skeleton of fish; no accumulation was reported for edible tissue
Key value for chemical safety assessment
Additional information
In freshwater aquatic organisms it was found that the fluoride accumulates primarily in the exoskeleton of crustacea and in the bones of fish. In fish, the BCF value was between 53 -58 (d.w.) and <2 (w.w.). In crustacea, BCF value was <1 (d.w.). The highest reported BCF value for mollusca and aquatic macrophyta were 3.2 and 7.5 (w.w) respectively. In an experimental marine ecosystem with fish, crustaceans and plants, fluoride was found to accumulate in all species. The highest value, 149, was found in fish. BCF values for crustacea range from 27 to 62. Fluoride concentrations up to 30 mg F/kg were found in consumption fish. The limited data indicate that fluoride biomagnification in the aquatic environment is of little significance.

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.
