  2. Fluoride - Wikipedia

    en.wikipedia.org/wiki/Fluoride

    Soluble fluoride salts, of which sodium fluoride is the most common, are toxic, and have resulted in both accidental and self-inflicted deaths from acute poisoning. [4] The lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride per kg body weight).

  3. Water fluoridation - Wikipedia

    en.wikipedia.org/wiki/Water_fluoridation

    The effect of water fluoridation on the natural environment has been investigated, and no adverse effects have been established. Issues studied have included fluoride concentrations in groundwater and downstream rivers; lawns, gardens, and plants; consumption of plants grown in fluoridated water; air emissions; and equipment noise. [83]

  4. Sodium in biology - Wikipedia

    en.wikipedia.org/wiki/Sodium_in_biology

    The sodium–potassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.

    Municipal water sources may have additives like chlorine or fluoride that can harm sensitive plants. Fertilize responsibly. A water-soluble fertilizer is usually best for indoor plants.

  6. Sodium fluoride - Wikipedia

    en.wikipedia.org/wiki/Sodium_fluoride

    Sodium fluoride (NaF) is an inorganic compound with the formula Na F.It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.

  7. Opposition to water fluoridation - Wikipedia

    en.wikipedia.org/wiki/Opposition_to_water...

    The effect of water fluoridation on the natural environment has been investigated, and no adverse effects have been established. Issues studied have included fluoride concentrations in groundwater and downstream rivers; lawns, gardens, and plants; consumption of plants grown in fluoridated water; air emissions; and equipment noise. [54]

  8. Biological aspects of fluorine - Wikipedia

    en.wikipedia.org/wiki/Biological_aspects_of_fluorine

    Ingested fluoride forms hydrofluoric acid in the stomach. In this form, fluoride crosses cell membranes and then binds with calcium and interferes with various enzymes. Fluoride is excreted through urine. Fluoride exposure limits are based on urine testing, which is used to determine the human body's capacity for ridding itself of fluoride. [69 ...

  9. Defluoridation - Wikipedia

    en.wikipedia.org/wiki/Defluoridation

    Disposal of fluoride-laden sludge is problematic. Precipitation is the most well-established and most widely used method, particularly at the community level. However, it has only moderate efficiency and a high chemical dose is required. Excessive use of aluminum salts produces sludge and adverse health effects through aluminum solubility.
