Local news station confirms barium in chemtrails

http://uk.youtube.com/watch?v=okB-489l6MI

Barium (pronounced /ˈbɛəriəm/) is a chemical element. It has the symbol Ba, and atomic number 56. Barium is a soft silvery metallic alkaline earth metal. It is never found in nature in its pure form due to its reactivity with air.Its oxide is historically known as baryta but it reacts with water and carbon dioxide and is not found as a mineral. The most common naturally occurring minerals are the very insoluble barium sulfate, BaSO4 (barite), and barium carbonate, BaCO3 (witherite). Benitoite is a rare gem containing barium.Barium is a metallic element is chemically similar to calcium but more reactive the metal oxidizes very easily when exposed to air and is highly reactive with water or alcohol producing hydrogen gas Burning in air or oxygen produces not just barium oxide (BaO) and the peroxide Simple compounds of this heavy element are notable for their high specific gravity This is true of the most common barium bearing mineral its sulfate barite BaSO4 also called heavy spar due to the high density 4.5 g/cm³

Precautions

All water or acid soluble barium compounds are extremely poisonous. At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea and paralysis. This may be due to its ability to block potassium ion channels which are critical to the proper function of the nervous system.

Barium sulfate can be taken orally because it is highly insoluble in water, and is eliminated completely from the digestive tract. Unlike other heavy metals, barium does not bioaccumulate.[2] However, inhaled dust containing barium compounds can accumulate in the lungs, causing a benign condition called baritosis.
Chemtrails have you seen them i have the differance between Chemtrails and contrails is contrails disapear after about 10-15 mins Chemtrails dont they dissapate over a longer peroid of time and contain deadly poisons ive seen them here in england and they have been seen all over the usa whats the adjenda about these Chemtrails

your inability to see the consequences of these chem-trails or the fact that they are continuing to spray our Sky's does not take away from the fact that many people in the USA have died from unknown respiratory ailments this said the effects are unknown and it would be hard to say how long you would have to be exposed to these before something happens to you and by then it could be to late.:?:

Nobody is deliberately spraying toxic chemicals into the upper atmosphere. I'm not wild about the billions of gallons of kerosine that we are burning in our airliners every month but contrails are mostly water and CO2 and a dozen or two other elements. Every once in a while somebody dusts off the stupid old "chemtrail" story and we all go round the bush once again.

this is nonsense. "contrails" are often the nucleation sites for clouds, some of which grow to cover the entire sky in any one place, so you can't say that contrails disappear after 10-15 minutes. Often they don't disappear, they actually linger and grow.

and what's the actual evidence that "chemtrails" exist and contain barium?

There are both high winds and periods of calm in the upper atmosphere. Contrails can sometimes linger, and sometimes disappear quite rapidly. That they hang around for a while doesn't mean they are part of a conspiracy to poison us. NASA doesn't believe in chemtrails, nor do I.

Atmospheric Geoengineering is occuring in our skies daily, and on a worldwide basis
For those who doubt the feasibility of these special operations, just take a look at the following Patents.

[SIZE=+1]Chemtrail Patents:[/SIZE]
[SIZE=-1]Method and apparatus for altering a region in the earth's atmosphere, ionosphere, and/or magnetosphere
[/SIZE]
[SIZE=-1]United States Patent 4,686,605 / Eastlund / August 11, 1987
[/SIZE]
[SIZE=-1]http://164.195.100.11/netacgi/nph-P...0&s1=4686605.WKU.&OS=PN/4686605&RS=PN/4686605[/SIZE]
[SIZE=-1]A method and apparatus for altering at least one selected region which normally exists above the earth's surface. The region is excited by electron cyclotron resonance heating to thereby increase its charged particle density. In one embodiment, circularly polarized electromagnetic radiation is transmitted upward in a direction substantially parallel to and along a field line which extends through the region of plasma to be altered. The radiation is transmitted at a frequency which excites electron cyclotron resonance to heat and accelerate the charged particles. This increase in energy can cause ionization of neutral particles which are then absorbed as part of the region thereby increasing the charged particle density of the region.[/SIZE]
[SIZE=-1]Method of modifying weather
[/SIZE]
[SIZE=-1]United States Patent 6,315,213 / Cordani / November 13, 2001
[/SIZE]
[SIZE=-1]http://164.195.100.11/netacgi/nph-P...0&s1=6315213.WKU.&OS=PN/6315213&RS=PN/6315213[/SIZE]
[SIZE=-1]A method for artificially modifying the weather by seeding rain clouds of a storm with suitable cross-linked aqueous polymer. The polymer is dispersed into the cloud and the wind of the storm agitates the mixture causing the polymer to absorb the rain. This reaction forms a gelatinous substance which precipitate to the surface below. Thus, diminishing the clouds ability to rain.[/SIZE]
[SIZE=-1]Process for absorbing ultraviolet radiation using dispersed melanin
[/SIZE]
[SIZE=-1]United States Patent / 5,286,979 / Berliner / February 15, 1994
[/SIZE]

[SIZE=-1]This invention is a process for absorbing ultraviolet radiation in the atmosphere by dispersing melanin, its analogs, or derivatives into the atmosphere. By appropriate choice of melanin composition, size of melanin dispersoids, and their concentration, the melanin will absorb some quantity of ultraviolet radiation and thereby lessen its overall effect on the critters who would normally absorb such radiation.[/SIZE]
[SIZE=-1]Liquid atomizing apparatus for aerial spraying
[/SIZE]
[SIZE=-1]United States Patent / 4,948,050 / Picot / August 14, 1990
[/SIZE]
[SIZE=-1]http://patft.uspto.gov/netacgi/nph-...0&s1=4948050.WKU.&OS=PN/4948050&RS=PN/4948050[/SIZE]
[SIZE=-1]A rotary liquid spray atomizer for aerial spraying is driven by a variable speed motor, driven in turn by power from a variable speed AC generator. The generator is driven from a power take-off from the engine of the spraying aircraft, a drive assembly includes a device for controlling the speed of the generator relative to the speed of the engine. The particularly convenient drive assembly between the generator and the power take-off is a hydraulic motor, which drives the generator, driven by a hydraulic pump driven from the power take-off. The speed of the hydraulic motor can be controllably varied. Conveniently the AC motor is a synchronous motor.[/SIZE]
[SIZE=-1]Laminar microjet atomizer and method of aerial spraying of liquids
[/SIZE]
[SIZE=-1]United States Patent / 4,412,654 Yates / November 1, 1983
[/SIZE]

[SIZE=-1]source: gisgaia[/SIZE][SIZE=-1]
------------------------------------------------------------------------
This is the "Description of Preferred Embodiments" link in the NASA Barium Patent listed above. Astounding that this information was generated in l969 and now,30 years later, there is evidence of Barium saturation in our atmosphere. [/SIZE]

[SIZE=-1]The Barium/Fuel mixtures are listed below along with the suppliers.

Description of Preferred Embodiments:
Referring now to the drawings and more particularly to FIG. 1, there is shown a segment of a suitable carrier vehicle 10, such for example a rocket motor. Vehicle 10 is employed to carry fuel tank 11, insulated oxidizer tank 13 and combustion chamber 15, along with the necessary instrumentation, from earth into the upper atmosphere or into interplanetary space. Fuel tank 11 is in fluid connection with combustion chamber 15 and oxidizer tank 13 is in fluid connection with combustion chamber 15 by way of respective conduits 17 and 19. A pair of valves 21 and 23 are disposed within the respective conduits 17 and 19. Valves 21 and 23 are adapted to be selectively and simultaneously opened by a suitable battery-powered timing mechanism, radio signal, or the like, to release the pressurized fuel and oxidizer from tanks 11 and 13. The fuel and oxidizer then flow through conduits 17 and 19 and impinge upon each other through a centrally positioned manifold and suitable jets (not shown) in combustion chamber 15 where spontaneous ignition occurs. The reaction products are then expelled through the open ends of combustion chamber 15 as plasma which includes the desired barium neutral atoms and barium ions as individual species. [/SIZE]

[SIZE=-1]The fuel utilized in fuel tank 11 is either hydrazine (N2 H4) or liquid ammonia (NH3) while the oxidizer employed is selected from the group consisting of liquid fluorine (F2), chlorine trifluoride (ClF3) and oxygen difluoride (OF2). When using hydrazine as the fuel, barium may be dissolved therein as barium chloride, BaCl2, or barium nitrate, Ba(NO3)2, or a combination of the two. When using liquid ammonia as the fuel, barium metal may be dissolved therein. The combination found to produce the highest intensity of Ba° and Ba+ resonance radiation in ground based tests involved a fuel of 16 percent Ba(NO3)2, 17 percent BaCl2 and 67 percent N2 H4 ; and as the oxidizer, the cryogenic liquid fluorine F2 and in which an oxidizer to fuel weight ratio was 1.32.
Other combinations of ingredients tested are set forth in Table I below: [/SIZE]

[SIZE=-1]A solubility study of various mixtures containing Ba(NO3)2, BaCl2 and N2 H4 was made at room temperature and is shown in the triangular plot of FIG. 2. Seven solutions that were used in the tests enumerated in Table I are indicated by reference letters in FIG. 2 as follows:
a. 16.7% BaCl2 - 83.3% N2 H4
b. 26% BaCl2 - 74% N2 H4
c. 21% BaCl2 - 9% Ba(NO3)2 - 70% N2 H4
d. 17% BaCl2 - 16% Ba(NO3)2 - 67% N2 H4
e. 13% BaCl2 -21.5% Ba(NO3)2 -65.5% N2 H4
f. 9% BaCl2 - 30% Ba(NO3)2 - 61% N2 H4
g. 42.9% Ba(NO3)2 - 57.1% N2 H4[/SIZE]

[SIZE=-1]A mixture below the Saturation Line, that is toward the Ba(NO3)2 or BaCl2 corners contained a solid and a solution phase whereas the salts were in complete solution above the saturation line.
All fuel mixtures or systems described were easily handled except the 50 percent Ba(NO3)2 -50 percent NH3 system. This system caused clogging of the feed valves due to precipitation of the Ba(NO3)2. In addition the light values obtained using this system was relatively low.
In testing of each of the fuel mixtures set forth in Table I the Ba° light was greater than the Ba+ light for a given oxidizer/fuel ratio in each of the mixtures. The maximum light occurred in all systems at a point located between the stoichiometric O/F and 3 percent less than the stoichiometric O/F. The stoichiometric O/F is defined as being equivalent to the oxidizer to fuel weight ratio in a balanced equation assuming the salt is converted to free Ba, F to HF, Cl to HCl and O to H2 O. For example, one system tested had an O/F ratio of 142 grams oxidizer per 100 grams fuel or 1.42/1.00. If the barium is assumed to be converted to BaF2 then the stoichiometric O/F is 1.47. Since the greatest light output in all cases occurred with O/F less than stoichiometric it is apparent that little of the Ba was combined as BaF2 or BaCl2. This was confirmed by spectrographic analysis.
In Table II the various systems are listed in decreasing light output or relative light intensity as measured by phototubes in millivolts, thereby indicating the relative barium yield.

[SIZE=-1]From the above information, it is readily seen that the 17 percent BaCl2 -16 percent Ba(NO3)2 -67 percent N2 H4 /F2 system gave the greatest amount of light intensity of the 4554 A Ba+ and 5535 A Ba° spectral lines. Ambient tests showed that the optimum oxidizer to fuel ratio of this system was 1.32 to 1.00. This system containing 8.52 weight percent barium was estimated to be 68.1 percent ionized. Also since this system had the largest relative light intensity it would be expected to give the greatest amount of Ba° and Ba+ and would appear to be the optimum system for a barium payload. In all systems tested it was found that the relative light reached a maximum at the O/F corresponding to the stoichiometric equation yielding barium as one of the reaction products and that the relative light output was sensitive to the O/F. Moving to either side of the optimum O/F caused a sharp decrease in relative light.
In vacuum tests the ignition of each system tested was smooth and like the ambient tests, took place in the combustion chamber. The rapid expansion in vacuum caused a decreased atom and ion density in the luminous flame which caused the light intensity to be about 1/37 to 1/50 the intensity measured in ambient tests. The percentage ionization was approximately the same for vacuum and ambient tests.
The operation of the invention is now believed apparent. Initially, fuel tank 11 is charged with the fuel containing the desired quantity of dissolved barium salt and pressurized with helium. The fuel tank pressure may be in the range of 6.89 to 20.06 ¥ 105 Newton/meter2. Oxidizer tank 13 is also charged with the appropriate oxidizer and pressurized. Cryogenic oxidizers such as OF2 and F2 are condensed from gases in the closed oxidizer tank which must be maintained enclosed in a liquid nitrogen bath. The oxidizer feed valve 23 and conduit 19 must also be maintained at liquid nitrogen temperature with a liquid nitrogen jacket when employing a cryogenic oxidizer.
The noncryogenic oxidizer, ClF3, may be pressurized into the closed oxidizer tank 13 from a supply bottle with super dry nitrogen.
Combustion chamber 15 is formed of stainless steel, aluminum, or the like F2 compatible metals and is internally partitioned by the manifold, not shown. The conduits 17 and 19 terminate in a manifold having injector orifices (not shown) mounted 90° to each other within each end of chamber 15 and sized for pressure drops of 5.24 to 10.2 ¥ 105 Newton/meter2 across the orifice. Fuel and oxidizer flows are in the range of 2.05 to 6.82 Kg/sec each. The entire system is carried into the upper atmosphere or interplanetary space by rocket vehicle 10 where, in response to a suitable signal, timing mechanism or the like, valves 21 and 23 may be selectively opened and closed and the pressurized liquid fuel and oxidizer will flow through conduits 17 and 19 into combination unit 15. When the hypergolic liquids impinge upon each other, they spontaneously ignite to expel reaction product gases or plasma including the highly luminous barium neutral atoms and barium ions as individual species. All of the barium reaching the combustion chamber is vaporized and released through the opposite ends thereof so that a high yield efficiency is obtained. The resulting high flame temperature, approximately 4,000°K., and some as yet not determined chemical activation, produces a relatively large amount of barium ions in the flame which is a highly desirable condition. It has been estimated from spectroscopic measurements that the degree of ionization may be as high as 75 percent in the released plasma in comparison to being on the order of 1 percent for the previously used Ba-CuO solid system which depends almost entirely on solar photoionization, a time-dependent phenomena which further reduces the usable barium yield of this known system.
Thus, it is readily apparent that the present invention provides an inherently more efficient process of producing barium clouds wherein the degree of ionization in the released plasma is much greater. The selectively opening and closing of valves 21 and 23 gives the possibility of a payload with multiple releases permitted due to the start and stop capabilities of the liquid system. Also, the liquid system of the present invention gives the possibility of controlling rates so that a trailtype release can be obtained as well as a point-source type. In addition, the liquid system of the present invention effects the formation of barium atoms and ions at the time of combustion and expansion at high temperatures and results in little opportunity for the barium to condense during release.
There are obviously many variations and modifications to the present invention that will be readily apparent to those skilled in the art without departing from the spirit or scope of the disclosure or from the scope of the claims.

tis amazing how quickly one resorts to using ridicule when one fails to come up with an argument...........

Show me one iota of proof that the government or some other agency has sprayed poison into the upper atmosphere. Why would anyone do this? Broadcasting poison that broadly would surely be self-defeating in that the poisoners would also be poisoned. Dopey idea.

What I gather from your article is that these tests were to determine how best to fight against a biological attack.
[QUOTE (from the article)]The results from these trials_ will save lives, should the country or our forces face an attack by chemical and biological weapons.'[/QUOTE]

In any case the tests were done thirty to fifty years ago.
