Sorry for the overload, but I thought today's broadcast on BBC Radio 4 in the UK was very important. It is related to fluoride in two ways.
First, fluorine was used in the separation of uranium isotopes. To separate the fissionable from the non-fissionable uranium isotope (isotopes do not differ chemically only physically - they have different atomic masses) the uranium is converted into uranium hexafluoride - a gas - and because gases diffuse at different rates depending on their masses - the two isotopes of Uranium can be separated in huge diffusion plants. In World War II this was done at the K-25 site in Oak Ridge, Tennessee, in the largest industrial building ever built. When I toured this facility in the mid-1990's there were hundreds of huge containers containing the debris from this process. How much of this debris ends up in depleted uranium weapons I do not know.
The manufacture of the atomic bomb during World War II used vast amounts of fluoride containing minerals as well as generating much fluoride air pollution and exposing workers in the plants to high levels of fluoride and a plethora of other toxic substances. Chris Bryson, in his book "The Fluoride Deception" (see www.FluorideAction.net) documents the involvement of the Manhattan project with the early development of water fluoridation. For example, Manhattan project officials like Dr. Harold Hodge were involved in the planning, execution and monitoring of the Newburgh-Kingston fluoridation trial (1945-55). Perhaps, we shouldn't be surprised that Harold Hodge had no compunction about testing fluoride on kids at 250 times the level that fluoride occurs in mothers' milk (0.004 ppm, NRC, 2006, Table 2-6, page 23) since this "respected toxicologist" had no qualms about injecting patients with plutonium, without their knowledge.
Second, the BBC story reveals that key health studies conducted by the U.S. Department of Defense on the dangers of depleted uranium, were kept out of a major WHO report on the health impacts of depleted uranium, probably because of U.S. pressures. So once again we see scientific integrity compromised in a large regulatory body overseeing our health. In this case, the world's health. WHO is also a supporter of fluoridation, again probably because of U.S. pressures.
We see here the same kind of "protected pollutant" status being granted to "depleted uranium" as we have seen with fluoride. Even though uranium is a metal and fluorine is a non-metal, they seem to have one common property - those in government (whether it is the EPA, CDC, FDA, NIH, and now WHO) who come into contact with either - lie. Often. Perhaps these officials graduated from Harvard, where students get an excellent training in how to sell science to the highest bidder (as well as government agencies) while wearing a shield inscribed with the motto: "veritas."
As far as the specifics of this particular case is concerned the BBC reporter says that "when depleted uranium bullets are fired, the rounds can rip through the tank armour. And once inside - on contact with air they combust exploding into a 10,000 degrees centigrade "ball of fire." In my view, such a fireball would generate vast quantities of very tiny particles (nanoparticles) which not only get deep down into the lungs but are so tiny that they evade the first line of defense of all our tissues - their membranes. Thus these nanoparticles can move rapidly through the membranes of the lung tissue into the blood stream and then quickly to every tissue in the body, where they can again pass through membranes (including the blood brain barrier) and create more havoc. Nanoparticles may well be the route cause of the long term health impacts experienced by the firefighters and local residents exposed to the huge pollution generated in the 9/11 attack on the World Trade Center. At least 30,000 people were impacted. Here we saw another atrocious lie from the head of the EPA, Christine Todd Whitman, who told people it was safe to work in and return to the area, even though she knew darm well that that was not true.
The "unconventional" dangers posed by nanoparticles is a red hot topic right now. They are also generated in incinerators (and other thermal treatment technologies) and the problem here is that they evade the most efficient air pollution control devices. This is a problem because both toxic metals and dioxins deposit on particles as a function of their surface area - the smaller the particle size the greater the overall surface area for a given mass. Moreover, the particles have very active catalytic properties capable of facilitating the formation of literally thousands of different compounds - many of them very toxic like chlorinated, brominated (and fluorinated?) dioxins, furans, and other less well characterized compounds.
