Moissan's fluorine cell, from his 1887 publication. Fluorine is a relatively new element in human applications. In ancient times, only minor uses of fluorine-containing minerals existed. The industrial use of fluorite, fluorine's source mineral, was first described by early scientist Georgius Agricola in the 16th century, in the context of ...
Their ultimate origin (from biological sources or geological formation) is unclear. [15] The possibility of small amounts of gaseous fluorine within crystals has been debated for many years. One form of fluorite, antozonite, has a smell suggestive of fluorine when crushed. The mineral also has a dark black color, perhaps from free calcium (not ...
Fluorine is a chemical element; ... Trace quantities of organofluorines of uncertain origin have been detected in volcanic eruptions and geothermal springs. [68]
Fluorine, in the form of fluoride, is considered to be a micronutrient for human health, necessary to prevent dental cavities, and to promote healthy bone growth. [28] The tea plant (Camellia sinensis L.) is a known accumulator of fluorine compounds, released upon forming infusions such as the common beverage. The fluorine compounds decompose ...
The fluorine mineral fluorospar was known as early as 1529. Early chemists realized that fluorine compounds contain an undiscovered element, but were unable to isolate it. In 1860, George Gore, an English chemist, ran a current of electricity through hydrofluoric acid and probably produced fluorine, but he was unable to prove his results at the ...
Domenico Lino Morichini [1] (23 September 1773 – 19 November 1836) was an Italian physician and chemist. He was the first to identify fluorine in teeth, first in a fossilized elephant tooth and then in human teeth.
PFAS have been shown to pose significant risks to human health and the environment. The urgency of PFAS remediation is underscored by stringent environmental regulations, such as the U.S. National Defense Authorization Act (“NDAA”), which mandated the transition to fluorine-free firefighting foams at DoD installations by October 2024.
Charles Betts, a prominent anti-fluoridationist, charged that fluoridation was "better than using the atom bomb because the atom bomb has to be made, has to be transported to the place it is to be set off while poisonous fluorine has been placed right beside the water supplies by the Americans themselves ready to be dumped into the water mains ...
