Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 EU RAR reviews and summarises the results of five short-term fish toxicity studies peformed with four species of freshwater fish exposed to sodium fluoride. It is noted that all tests considered to be reliable were performed in soft water and all endpoints are expressed in terms of fluoride anion equivalents. Short term LC50 endpoints for fish exposed in soft-water to sodium fluoride range from 51 (2,68 mmol/l) to 340 mg fluoride anion per liter. This is equivalent to a range of 133 to 888 mg of WF6 per liter. Please note that WF6 is hydrolizing rapidly into HF and WOx compounds, when exposed to moisture. WF6 is not intended to get in contact with any environmental compartment and these values should be considered as only hypotheticaly.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
