The newscast focuses on Barium, which its research shows is a "hallmark of chemtrails." KSLA found Barium levels in its samples at 6.8 ppm or "more than six times the toxic level set by the EPA." The Louisiana Department of Environmental Quality confirmed that the high levels of Barium were "very unusual," but commented that "proving the source was a whole other matter" in its discussion with KSLA.

KSLA also asked Mark Ryan, Director of the Poison Control Center, about the effects of Barium on the human body. Ryan commented that "short term exposure can lead to anything from stomach to chest pains and that long term exposure causes blood pressure problems." The Poison Control Center further reported that long-term exposure, as with any harmful substance, would contribute to weakening the immune system, which many speculate is the purpose of such man-made chemical trails.

Wikipedia warns about Barium's highly reactive nature and potential harm to health:

Barium is a soft silvery metallic alkaline earth metal... never found in nature in its pure form due to its reactivity with air. It is also highly reactive with water or alcohol, producing hydrogen gas.

Its various compounds have a number of industrial uses including x-ray imaging, rat poison, battery technology, lighting and electricity.

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.

Unlike other heavy metals, barium does not bioaccumulate.[1] However, inhaled dust containing barium compounds can accumulate in the lungs, causing a benign condition called baritosis.

Barium acetate could lead to death in high doses. Marie Robards poisoned her father with the substance in Texas in 1993. She was tried and convicted in 1996.

KSLA also put aerosolized-chemical testing in its historical context, citing a voluminous number of unclassified tests exposed in 1977 Senate hearings. The tests included experimenting with biochemical compounds on the public. KSLA reports that "239 populated areas were contaminated with biological agents between 1949 and 1969."

On screen representations included 'Operation bacterium', '1949 germ bombs' (explosive munitions tests with pathogens), '1950 "first" open-air tests' with biological agents (coast of Norfolk, VA) and the '1950 spraying of San Francisco' (the first large-scale aerosol test using Bacillus globigii (also known as Bacillus subtilis) and Serratia marcescens, both similar to B. anthracis (a causative agent of anthrax). These examples were only the beginning of a long chronological list.

Chemtrails, keeping you in line.

I have been seeing more talk about chemtrails being a way to disperse toxins/diseases.

With all of the protests and unrest beginning to sweep the nation, consider this. If the chemtrail phenomenon is able to cover large areas with a toxic substance, and people knew about it, people may be forced to seek refuge.

Great example, alot of survivalists talk about running up into the woods or mountains in a SHTF scenario. What happens if a disease is sprayed over a large wooded area, and that disease targets humans to either kill or maim?

What happens if a chemical is sprayed over a city experiencing an uprising, and that chemical is supposed to cause shortness of breath or other lung problems, and the media were to make a ton of hype about it? Might the described scenario keep people hiding indoors?

What if chemtrails are the way that America's final step of being shut down takes place? What if chemtrails full of a virus that attacks humans is the panic button that is either silently or threatened to be pushed should TPTB, well, panic?

The inert aluminum spread by the jets is not considered a human health hazard. But according to the New England Journal of Medicine, microscopic particles in the air can kill city dwellers prematurely. Further, a 1993 Harvard study has identified particles with a diameter of less than 10 micrometres (microns) as a threat to public health. Death rates increase with the rise in particulate pollution.

Nevertheless, a leaked draft document from the International Panel on Climate Change said the panel considers spraying up to 10 million tons of microscopic aluminum particles "in the range of 10 to 100 microns" as a possible solution to avoid global warming.
