Metal toxicity is an important actor limiting the growth o plants in many environments. Some metals, such as copper and zinc, are micronutrients at low concentrations and become toxic at higher levels, whereas others (e.g. aluminium and lead) are only known or their toxicity. In some cases, soils are naturally very high in metals. An example is the serpentine soils, which have elevated levels o chromium, cobalt, iron, magnesium and nickel, but are very low in calcium. Low soil pH makes most metals more available or plant uptake and can indirectly lead to metal toxicity (e.g. through acid rain)
Metal toxicity is responsible or many visual symptoms in plants. Root growth is oen reduced, and leaves may change colour. Competition with nutrient ions oruptake by roots can cause deciency symptoms (e.g.aluminium causes calcium or magnesium deciency).In a similar way, binding o toxic metals with proteins and other compounds because they resemble essential metals can also cause toxicity. Te plasma membrane o root cells is oen damaged by exposure to toxic metals,resulting in leakage o cellular solutes
Chronic lead exposure has been associated with elevated blood pressure in epidemiological studies. It is not known whether the previously observed relation between blood lead and hypertension persists after significant reductions have been made in environmental lead contamination. We examined the relation between blood lead levels and blood pressure in a representative sample of 14 952 whites and blacks aged 18 years or older who participated in the Third National Health and Nutrition Examination Survey. Blood lead was measured by atomic absorption spectrophotometry and blood pressure by standard sphygmomanometry. Mean blood lead levels were significantly higher for black men and women (5.4 and 3.4 μg/dL, respectively) compared with white men and women (4.4 and 3.0 μg/dL, respectively). After multivariate adjustment for important covariables, each standard deviation higher blood lead (3.3 μg/dL) was associated with a 0.82 (95% confidence interval [CI], 0.19 to 1.44) mm Hg and a 1.55 (95% CI, 0.47 to 2.64) mm Hg higher systolic blood pressure among black men and women, respectively. In contrast, blood lead level was not associated with blood pressure among white men or women.
Uncontrolled high blood pressure damages the brain's structure and function as early as young middle-age, and even the brains of middle-aged people who clinically would not be considered to have hypertension have evidence of silent structural brain damage, a study led by researchers at UC Davis has found.
The investigation found accelerated brain aging among hypertensive and prehypertensive individuals in their 40s, including damage to the structural integrity of the brain's white matter and the volume of its gray matter, suggesting that vascular brain injury "develops insidiously over the lifetime with discernible effects."
The study is the first to demonstrate that there is structural damage to the brains of adults in young middle age as a result of high blood pressure, the authors said. Structural damage to the brain's white matter caused by high blood pressure previously has been associated with cognitive decline in older individuals.
It found an average blood mercury level of 50 nanomoles per liter of blood, much higher than the 4-nanomole level of the general U.S. population. It also found a relationship between blood mercury levels and blood pressure after adjusting for other factors, such as smoking and physical activity.
Studies have shown that exposure to environmental mercury can affect the endothelium, the delicate lining of blood vessels, and decrease the ability of smooth muscles to relax, which could explain the slight increase in blood pressure seen in the study, Dewailly said.
THURSDAY, Oct. 24, 2013 (HealthDay News) -- People who take certain commonly used blood pressure medications have a significantly lower risk for Alzheimer's disease than those who don't, a new study suggests.
Although it remains unclear exactly how drugs such as ACE inhibitors or diuretics might protect the brain, researchers say these new findings could lead to a better understanding of Alzheimer's and new treatments to slow or delay the progression of the memory-robbing disease.
"We found a risk reduction by 50 percent. That tells you there must be something there," said study leader Dr. Sevil Yasar, an assistant professor of medicine in the department of geriatric medicine and gerontology at the Johns Hopkins University School of Medicine.
Hazardous materials are being sprayed over the population
In January 2014, at the 1st Annual Save Long Island event, I was invited to talk about the dangers of GMOs. But, it was the presentation of Kristen Meghan, a former Air Force Bioenvironmental Engineer turned whistleblower that really has me concerned about the future of humanity.
If you ever wondered about the most serious global issue of our time – chemtrails – this video (below) is a must to watch and share with your family and friends.
Think about it – these spraying projects place tons of tiny (toxic) particles of aluminum oxide, barium and strontium into our atmosphere and, eventually, our lungs – causing a wide variety of health issues like, nausea, diarrhea, headache, eczema, cardiac deaths and many upper respiratory illnesses.
Of course, conventionally-trained family physicians will tell you it’s an ‘allergy’ and prescribe drugs. But, you and I both know the real cause is an overabundance of environmental and food-related toxins.
Mention strontium to most people, and they will almost always immediately think of strontium-90, a highly dangerous, radioactive component of nuclear fallout produced during atmospheric testing of nuclear weapons in the 1950s. As a result of above-ground nuclear testing, radioactive strontium spread throughout the environment and contaminated dairy products and other foods, and subsequently accumulated in the bones of both children and adults.
Furthermore, repeatedly administering stable strontium can even gradually eliminate radioactive strontium from the body. The stable form slowly replaces the radioactive form in bone, and radioactive strontium is excreted in the urine.
Strontium is element number 38 of the periodic table of elements. It was discovered in 1808 and was named after Strontian, a town in Scotland. Strontium is one of the most abundant elements on earth, comprising about 0.04 percent of the earth's crust. At a concentration of 400 parts per million, there is more strontium in the earth's crust than carbon. Strontium is also the most abundant trace element in seawater, at a concentration of 8.1 parts per million. The human body contains about 320 mg of strontium, nearly all of which is in bone and connective tissue.
Strontium tends to accumulate in bone&emdash;especially where active remodeling is taking place. In 1959, researchers at the Mayo Clinic investigated the effect of strontium in 32 individuals suffering from osteoporosis.1
Mick, the confusion lies with people who aren't familiar with my activism, my whistleblower label is not related to chemtrails. I'm been doing media for a while and chemtrails is just one item I discuss. When I do shows they introduce me as a whistleblower but the topic I discuss that day isn't why I was a AF whistleblower. What I have brought to the table about chemtrails is that I personally saw the processes going on at Tinker AFB. I've never said anything more than that, nor embellished on any of that data. I did samples and I still take samples here in Chicago for a study I am doing. In this interview below, you can see I contribute to media for differnct reasons. I don't know if you have heard of Adam Kokesh, Danny Panzella, or Gary Franchi... these are people who also do this and I look up to them.
The title is very clear as the understanding for chemtrails begins with the process of history for anthropological problems and the development of the tread leads to the chemtrails issues. Aluminum uptake is a factor in acid rain, also common to chemtrails. So, to begin the history of the co-related issues-----the title clearly states it starts with acid rain, then develops in the later thread content.
First Rule of Understanding: There are very large, winner-take-all games orchestrated by the Global Interests of the World. We have investigated, researched and found substantial evidence of a multiplicity of Global operations designed to mitigate various and theoretical Global catastrophes, as defined by a late 1980's and 1990's International Panel of Conferees. (The value of who are they, what's the politics smell like and all that is not of the utmost importance in our attempt, herein, to describe what serious destruction they have caused and are causing to Humans and our Finite Environment.

Dr. Edward Teller wrote a white paper in the late 1990's describing a remedial operation, strategy, epic-in-proportion, to change the predicted course of what was believed by an International group of Scientists, including Dr. Edward Teller, Livermore National Laboratories, et al, to be the cataclysmic certainty from the results of global-warming, crisis level Ultra-Violet/Cosmic radiation, crisis Ozone-layer depletion and other theoretical doom.
Such methods came to support the Pentagon studies for total weather control by 2020, as part of the globalist methods. There had long been wealth warfare and it was seen in Vietnam with cloud seeding to keep the supply lines of the Communist flooded and delayed.
What about the toxic crap spewed out by volcanoes every single day/hour? hydrogen, helium, hydrogen sulfide, carbon dioxide,
carbon monoxide, sulfur, smoke particulates, ash, cannot remember any more.
