Calcium fluoride (CaF2) occurs naturally in some underground waters. [Also found on the planet Mars, See HERE.] It is not used for artificial water fluoridation. – It is not a industrial waste looking for a market! It occurs naturally and is a health hazard in many countries, as can been seen in our documents on
‘Chronic Endemic Fluorosis Of Merino Sheep In Queensland‘ – (Sheep drinking underground bore water.) – See below → *♦ * ←
Sodium fluoride (NaF) is an inorganic compound. It is used in the fluoridation of drinking water, also in metallurgy, and as a flux, and is also used in pesticides and rat poison. –
(Disodium hexafluorosilicate – Sodium silicon fluoride –
Unlike the fluoride compounds found in toothpaste or supplements, these fluoridation chemicals are not pharmaceutical grade quality and are contaminated with heavy metals e.g. – fluosiloxanes, aluminium, iron, arsenic, beryllium, cadmium, nickel, lead, mercury, chromium, sulfides, (and radionuclides, polonium) they are used to fluoridate drinking water.
– Typical analysis:
Hexafluorosilicic acid. (H3O)2[SiF6 ]) It is a colorless liquid mostly encountered as diluted aqueous solution. It is produced naturally on a large scale in volcanoes. It is manufactured as a co-product in the production of phosphate fertilizers.

Sulfur hexafluoride (SF6) is the most potent
greenhouse gas that it has evaluated, with a ‘g’ of
22,800 times that of → CO2 ← when compared over a 100-year period. More than 10,000 tons are produced per year.
Both Hydrofluoric acid, (HF) & Nitrogen trifluoride, (NF3) have characteristics that must be managed for safe use and release. HF is a highly toxic and corrosive gas that can have significant health consequences if an individual is exposed.
HF is also a highly reactive gas that can react with certain metals to release toxic fumes or explosive hydrogen. Nitrogen trifluoride (NF3) with a global warming potential of 17,000 times the global warming potential of CO2. It is now present in the atmosphere at four times the expected level and rapidly rising. NF3 is toxic, and is only reactive at high temperatures and when exposed to certain physical conditions. Nitrogen trifluoride appears as a colorless gas with a moldy odor. Very toxic by inhalation. Slightly soluble in water. Corrosive to tissue. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Used to make other chemicals and as a component of rocket fuels.
It Is a gas used in flat-screen TV manufacture.
P.S. – More Fluoride Troubles:
Sulfuryl fluoride (SO2F2), is just the latest of several unexpectedly potent greenhouse gases to pop out of the woodwork. The common factor appears to be fluorine.
It is neurotoxic and a potent greenhouse gas, but is widely used as a fumigant insecticide to control termites. ←
Last year, for instance, it emerged that nitrogen trifluoride, a gas used in flat-screen TV manufacture, has 17,000 times the global warming potential of CO2 .
In 2000, researchers analysing samples of Antarctic snow and air discovered contamination with trifluoromethlyl sulphur pentafluoride, (SF 5CF 3), which turned out to be 18,000 times more potent green house gas than CO2 per molecule.
It is a rare industrial gas, – “a super-greenhouse gas”.

is 50 times smaller than that of CaF2 the
naturally-occurring Calcium fluoride.”
