  • Fluoride - Wikipedia

    This neutralization reaction forms hydrogen fluoride (HF), the conjugate acid of fluoride.. In aqueous solution, fluoride has a pK b value of 10.8. It is therefore a weak base, and tends to remain as the fluoride ion rather than generating a substantial amount of hydrogen fluoride.That is, the following equilibrium favours the left-hand side in water:

  • Fluoride: 3. How are humans exposed to fluorides?

    The concentrations of fluoride in unwashed or unprocessed foods grown near industrial fluoride sources may be greater than the levels in the same foods grown in other non-industrially exposed areas. Fluoride has been detected in breast milk at concentrations up to 100 µg /litre, with most measurements ranging between 5 and 10 µg/litre.

  • Fluoride: 3. How are humans exposed to fluorides?

    The use of water containing relatively low levels (less than about 3 mg/litre) of fluoride for crop irrigation generally does not increase fluoride concentrations in foodstuffs, but this depends on plant species and fluoride concentrations in soil and water. However, the level of fluoride in foods is significantly affected by the fluoride content of the water used in food preparation or ...
