Fluoride Poisoning Risk and Volcanic Eruptions

Experts differ on health risk of volcanic ash

You are not hearing in the mainstream media the health risk concerns of the recent volcanic eruption in Iceland.  Here is information you should know -
As usual, the UN and North American news do not mention the dangers of fluoride in volcanic ash, as it relates to yesterday's eruption.

The Russian paper Pravda was the only one I could find.


Compare to UN news:

"Even if these values are only about one third of comparable values for Hekla ash it is there,and  is reason to be careful and move grazing animals form ash-contaminated fields and melt-water."

Evaluating a fluorosis hazard after a volcanic eruption.

The August, 1991 eruption of Mt. Hudson (Chile) deposited ash across southern Argentina and contributed to the deaths of thousands of grazing sheep. Early ash analysis revealed high levels of fluoride, a potential ash constituent toxic to humans and animals. In order to evaluate fluorosis as the cause of sheep deaths and to examine the possibility that similar ash and airborne toxins could also have an effect on the human population, we conducted an investigation that included health provider interviews, hospital record review, physical examination of sheep, determination of sheep urine fluoride levels, and complete constituent analysis of ash samples collected at proscribed distances from the volcano. Ash deposited farthest from the volcano had highest fluoride levels; all fluoride measurements were normal after rainfall. There were no signs or symptoms of fluorosis observed in sheep or humans. Sheep deaths resulted from physical, rather than chemical properties of the ash. PMID: 7944572 [PubMed - indexed for MEDLINE]

Fortunately the flouride gets bound to calcuim and magnesium, and both the salts have low solubility in water.

But historically, poisonings of livestock and humans, have several preceeding cases in Icelands history.
