According to the U.S. Department of Agriculture,
“Airborne fluorides have caused more worldwide
damage to domestic animals than any other air pollutant.”

Some pine trees are very sensitive to fluorides and can be used
as bio-indicators for air [and water] pollution.
Some ferns and rain forest plants can show sensitivity to fluoride when watered on their foliage.
Fluoride-induced injury (air pollution) to coniferous forests can occur at a distance of 32 km from an emitting source, and total destruction of some species at 13 km distance. Fluorides are released into the air in both a gaseous state (as hydrogen fluoride and silicon tetrafluoride) and in solid particles. The particles fall on, and the gases are absorbed by, vegetation near the polluting industry [or volcano]. If this vegetation includes forage crops, which are fed to cattle, sheep, horses, pigs, or kangaroos. (The EPA says fluoride from Alcoa’s aluminium smelter at Portland [Victoria] is making kangaroos sick. 23 Feb. 2010), serious problems can ensue, since these animals, particularly cattle are vulnerable to fluoride. In fact, according to the U.S. Department of Agriculture, “Airborne fluorides have caused more worldwide damage to domestic animals than any other air pollutant.”

Huge compensation payments have been made, – mostly as out of court settlements.
❝ The thing to note with plants is that plants will readily absorb fluorine that is sprayed [(irrigation,) or falls] on the leaves. If flood [or drip] irrigation is used, the plants accumulate far less fluoride due to calcium absorption in the soil and the plant’s discriminatory uptake through the roots ❞ – Dr. Miller.

Q. If crops are grown where there is fluorine contamination do they take up the fluorine and pass the trouble on to somebody else ?
A. [R. Allcroft] No, it is not a case of passing it on to somebody else. It has been shown that most plants do not take up fluorine from the soil. There are exceptions: the tea plant and the camellia which appear to be fluorine collectors. Most grasses and root crops do not take it up from soils. It is mostly a question of contamination of the surface, there-fore humans get off lightly because we do not eat grass. The inner parts of cabbages and similar crops are not high in fluorine, only the outer coverings which are removed. Cereal grains are also quite safe…
