Description of key information

HF is unstable and will rapidly hydrolyse in the environment and react to form other fluorine-containing compounds. The behaviour of fluoride in water is dependent on pH and mineral content. Fluoride is deposited to sediment as insoluble complexes and is essentially immobile in soil due to its incorporation into insoluble complexes. Adsorption to the soil solid phase is stronger at slightly acidic pH values (5.5–6.5). Fluoride is not readily leached from soils.
