Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No data are required. This endpoint is not relevant for an inorganic substance. Ammonium fluoride hydrofluoride is a simple inorganic compound and therefore will not be biodegraded.
Key value for chemical safety assessment
Additional information
Ammonium fluoride hydrofluoride is a simple inorganic compound and therefore will not be biodegraded as such. The substance will exist in the aqueous environment predominantly as its consituent ions. However in soil, ammonia is readily converted by a variety of bacteria, actinomycetes and fungi to ammonium (NH4+) by the process of ammonification or mineralization. Ammonium is then rapidly converted to nitrate. Nitrate is subsequently taken up and utilised by plants or returned to the atmosphere following denitrification; the metabolic reduction of nitrate into nitrogen or nitrous oxide (N2O) gas. he most likely fate of ammonium ions in soils is conversion to nitrates by nitrification.
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.
