Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The toxicity of fluorine to fish is derived from ecotoxicity data of its degradation product fluoride. The 96-h LC50 value for fluoride is 51 mg/L in rainbow trout.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 51 mg/L
Additional information
No aquatic toxicity studies with fluorine are available or can be performed as in contact with water fluorine reacts instantly and violently under formation of hydrogen fluoride. Hydrogen fluoride will further react to fluoride. Therefore available data from studies with fluoride are given as indication of the aquatic toxicity of fluorine.
In the EU Risk Assessment Report for hydrogen fluoride several fish studies are reported. All reported tests were performed with sodium fluoride and the results were corrected for the fluoride ion. From the different studies reviewed in this report, the lowest effect-value was observed in rainbow trout with a 96-h LC50 of 51 mg fluoride/L. Although methodological data are incomplete, the data have been reviewed by the EU and are therefore considered to be suitably reliable for environmental risk assessment.
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.
