This stuff doesn't look as bad as I thought it was. I had pain in lung 2 times and bleeding and I thought it might have something to do with the barium but now I see it can't have been possible. Is there anything on aluminum oxide?

More on Barium:
A number of accidental barium poisonings have occurred following the ingestion of barium salts. The acute symptoms include excess salivation, vomiting, diarrhea, increased blood pressure, muscular tremors, weakness, paresis, anxiety, dyspnea, and cardiac irregularities. A severe loss of potassium can account for some of the symptoms. Convulsions and death from cardiac and respiratory failure can occur. Magnesium and sodium sulfate are antidotal if taken soon after ingestion since either salt will result in the formation of insoluble barium sulfate and prevent further absorption. http://risk.lsd.ornl.gov/tox/profiles/barium_f_V1.shtml

Here's one other article, but not much information other than basically don't breath this s!@#! 
http://www.cdc.gov/niosh/ipcs/ipcs0351.html
The clouds illuminated by the moon last night were reddish. I feel like I'm living in a chemical waste dump. I wish those zombies in the military had more compassion for the people and environment they are poisoning.

Call a physician.
-------------------------------------------
haha, so I am supposed to spend the rest of my life with my head in the sink flushing that crap out of my eyes. Somebody's idea of a sense of humor, not mine. I don't even try to explain the constant flow of tears when I am outside or have been outside. Does anyone have the number for the physician I am supposed to call for the remedy? |

Hi Herbivore,
I can sympathize with your irritated eyes. I’ve had reddened eyes off and on for some time which I could not explain. I think I understand why now due to these particles. Having to flush one’s eyes after having chemtrails evident is inconvenient, but better to know what to do than not. I’ve also suffered from chronic sinus problems since 1999 and I am now wondering if they may be related to chemtrails.
If you are especially allergic to things, I suggest you try a liver/gallstone cleanse to get out gall/liver stones naturally. Some people have said these cleanses reduce their allergies in general due to better functionality of the liver. Hulda Clark is the biggest proponent of the liver cleanse. I’ve done it twice and gotten out many ‘stones’. The cleanse is at http://www.drclark.net/info/liver.htm. Her book is “The Cure for all Diseases”.

That Dr Clark really does know her stuff. I have used her treatment for parasites. She is right on.
I have certainly stepped up on parsley and vitamin K intake. Both are quite good for the liver. Also drinking lots of water is highly advisable. |

Hi Thermit,
Yes, I felt better after each cleanse. I probably got out around 25 pea sized stones per cleanse along with a lot of smaller 'chaff'. I got out a stone about 3/4 inches in diameter in the second cleanse. I could not believe it. I am reasonably athletic and generally in good shape. I am currently doing a kidney cleanse.
The liver produces up to a quart of bile which exits to the colon via the gall bladder. If the gall bladder is filled with stones the plumbing can get backed up with all sorts of associated health problems! Also, the stones can be backed up in the liver in the bile ducts besides the gall bladder.
500,000 people have their gall bladder removed in the US every year. We can preventatively get the stones out before the bladder gets chock full of stones and its too late. All for about $5 or less of materials per cleanse. It's simply one of the most healthful and amazing things you can do for yourself. Do the parasite cleanse first for best results. It's all in her book.

Here's some more disturbing information about Barium.
The soluble salts of barium, an alkaline earth metal, are toxic in mammalian systems. They are absorbed rapidly from the gastrointestinal tract and are deposited in the muscles, lungs, and bone. Barium is excreted primarily in the feces.
At low doses, barium acts as a muscle stimulant and at higher doses affects the nervous system eventually leading to paralysis. Acute and subchronic oral doses of barium cause vomiting and diarrhea, followed by decreased heart rate and elevated blood pressure. Higher doses result in cardiac irregularities, weakness, tremors, anxiety, and dyspnea. A drop in serum potassium may account for some of the symptoms. Death can occur from cardiac and respiratory failure. Acute doses around 0.8 grams can be fatal to humans.
Subchronic and chronic oral or inhalation exposure primarily affects the cardiovascular system resulting in elevated blood pressure. A lowest-observed-adverse-effect level (LOAEL) of 0.51 mg barium/kg/day based on increased blood pressure was observed in chronic oral rat studies (Perry et al. 1983), whereas human studies identified a no-observed-adverse-effect level (NOAEL) of 0.21 mg barium/kg/day (Wones et al. 1990, Brenniman and Levy 1984). The human data were used by the EPA to calculate a chronic and subchronic oral reference dose (RfD) of 0.07 mg/kg/day (EPA 1995a,b). In the Wones et al. study, human volunteers were given barium up to 10 mg/L in drinking water for 10 weeks. No clinically significant effects were observed. An epidemiological study was conducted by Brenniman and Levy in which human populations ingesting 2 to 10 mg/L of barium in drinking water were compared to a population ingesting 0 to 0.2 mg/L. No significant individual differences were seen; however, a significantly higher mortality rate from all combined cardiovascular diseases was observed with the higher barium level in the 65+ age group. The average barium concentration was 7.3 mg/L, which corresponds to a dose of 0.20 mg/kg/day. Confidence in the oral RfD is rated medium by the EPA.
Subchronic and chronic inhalation exposure of human populations to barium-containing dust can result in a benign pneumoconiosis called "baritosis." This condition is often accompanied by an elevated blood pressure but does not result in a change in pulmonary function. Exposure to an air concentration of 5.2 mg barium carbonate/m3 for 4 hours/day for 6 months has been reported to result in elevated blood pressure and decreased body weight gain in rats (Tarasenko et al. 1977). Reproduction and developmental effects were also observed. Increased fetal mortality was seen after untreated females were mated with males exposed to 5.2 mg/m3 of barium carbonate. Similar results were obtained with female rats treated with 13.4 mg barium carbonate/m3. The NOAEL for developmental effects was 1.15 mg/m3 (equivalent to 0.8 mg barium/m3). An inhalation reference concentration (RfC) of 0.005 mg/m3 for subchronic and 0.0005 mg/m3 for chronic exposure was calculated by the EPA based on the NOAEL for developmental effects (EPA 1995a). These effects have not been substantiated in humans or other animal systems.
Barium has not been evaluated by the EPA for evidence of human carcinogenic potential (EPA 1995b).
3.1 ORAL EXPOSURES
3.1.1 Acute Toxicity
3.1.1.1 Human
A number of accidental barium poisonings have occurred following the ingestion of barium salts. The estimated fatal dose of barium carbonate, a rodenticide, is about 5 grams for a 70 kg human (Arena 1979). The LD50 for barium chloride is estimated at about 1 gram for a 70 kg human (Machata 1988), and the LDLo (lowest published lethal dose) is reported to be about 0.8 grams (Lewis and Sweet 1984). The acute symptoms include excess salivation, vomiting, diarrhea, increased blood pressure, muscular tremors, weakness, paresis, anxiety, dyspnea, and cardiac irregularities. A severe loss of potassium can account for some of the symptoms. Convulsions and death from cardiac and respiratory failure can occur. Magnesium and sodium sulfate are antidotal if taken soon after ingestion since either salt will result in the formation of insoluble barium sulfate and prevent further absorption. Survival for more than 24 hours is usually followed by complete recovery (Arena 1979).
Complications occurred in a woman following a barium swallow investigation for severe dysphagia. Direct aspiration of a large amount of barium into the right main bronchus resulted in tachycardia, tachypnoea, fever, and an oxygen saturation of 82%; two weeks later the woman still had a moist cough with widespread rales but continued to recover (Penington 1993).
A family was accidentally poisoned with barium from eating their evening meal. The mother had fried fish breaded with a flour-like substance that turned out to be rat poison containing barium carbonate. All seven family members, aged 2 to 48 years, developed nausea, vomiting, diarrhea, and crampy abdominal pain within minutes of consuming the meal; the parents also developed ventricular tachycardia, flaccid paralysis of the extremities, shortness of breath (mother), and respiratory failure (father). Patients were treated symptomatically and all fully recovered (Johnson and VanTassell 1991).
3.2 INHALATION EXPOSURES
3.2.1 Acute Toxicity
3.2.1.1 Human
Barium carbonate dust has been reported to be a bronchial irritant. Barium oxide dust is considered a dermal and nasal irritant (Beliles 1994). The effect of barium dusts on welders was investigated under simulated working conditions over a one-week time period (Zschiesche et al. 1992). Barium fume concentrations were 4.4 and 2.0 mg/m3 during welding with stick electrodes and flux cored wires, respectively. No adverse health effects on the welders were attributable to barium exposure, but there was a slight decrease in plasma potassium levels at the end of the work shift.

And just a little bit more information on Barium.
From 1987 to 1993, according to the Toxics Release Inventory barium compound releases to land and water totaled over 57 million lbs. These releases were primarily from copper smelting industries. The largest releases occurred in Arizona and Utah. The largest direct releases to water occurred in Texas.
What happens to Barium when it is released to the environment? In water, the more toxic soluble barium salts are likely to be converted to insoluble salts which precipitate. Barium does not bind to most soils and may migrate to ground water. It has a low tendency to accumulate in aquatic life.
Effect:
Short-term: EPA has found barium to potentially cause the following health effects when people are exposed to it at levels above the MCL for relatively short periods of time: gastrointestinal disturbances and muscular weakness.
Long-term: Barium has the potential to cause the following effects from a lifetime exposure at levels above the MCL: high blood pressure.
Followup:
Treatment:
Ion Exchange, Reverse Osmosis, Lime Softening, Electrodialysis.
