Biological Aspects
See also: Fluoride deficiencyFluoride is not considered an essential mineral element for mammals and humans. Small amounts of fluoride may be beneficial for bone strength, but this is an issue only in the formulation of artificial diets. Food and drinking water typically contain at least small amounts of fluorides, which are naturally present.
Several other biological aspects of fluorine exist. Fluoride is widely used for prevention of dental cavities. In pharmaceuticals and agrichemicals, fluorine sees increasing use in new molecules. Both radioactive and natural fluorine isotopes are important in respective scanning applications. Oxygen-carrying perfluorocarbons present a possibility for human liquid breathing. Poisons containing fluorine are well known for killing insects and rodents and the very few organisms that incorporate fluorine in their biochemistry do so to make natural poisons.

Famous quotes containing the words biological and/or aspects:
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
“It is always a sign of an unproductive time when it concerns itself with petty and technical aspects [in philology], and likewise it is a sign of an unproductive person to pursue such trifles.”
—Johann Wolfgang Von Goethe (1749–1832)
