I own a telescope, it sits outside and I have seen big, white, unmarked aircraft leave hideous trails of pollutants that take an hour to completly spread and combined with the other chemtrails acting in the same way block the sun but give me beautifully colored sunsets.
How much Barium is produced and released to the environment?
The most common ores are found in AK, AR, CA, GA, KY, MO, NV, and TN. Barite was produced at 38 mines in these states in 1973, with Nevada supplying 50% of the tonnage. Barium is released to water and soil in the discharge and disposal of drilling wastes, from the smelting of copper, and the manufacture of motor vehicle parts and accessories.
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.
Heavy metals in the environment are caused by air emissions from coal-burning plants, smelters, and other industrial facilities; waste incinerators; process wastes from mining and industry; and lead in household plumbing and old house paints. Industry is not totally to blame, as heavy metals can sometimes enter the environment through natural processes. For example, in some parts of the U.S., naturally occurring geologic deposits of arsenic can dissolve into groundwater, potentially resulting in unsafe levels of this heavy metal in drinking water supplies in the area. Once released to the environment, metals can remain for decades or centuries, increasing the likelihood of human exposure.
In addition to drinking water, we can be exposed to heavy metals through inhalation of air pollutants, exposure to contaminated soils or industrial waste, or consumption of contaminated food. Because of contaminated water, food sources such as vegetables, grains, fruits, fish and shellfish can also become contaminated by accumulating metals from the very soil and water it grows from.
Why is aluminum present in water?
Aluminum forms during mineral weathering of feldspars, such as and orthoclase, anorthite, albite, micas and bauxite, and subsequently ends up in clay minerals. A number of gemstones contain aluminum, examples are ruby and sapphire.
Currently, only iron and steel are produced in larger amounts than aluminum. Additionally, aluminum is largely recycled because this is very distinctly possible. It is applied in for example frames, door knobs, car bodies, plane parts (the weight/ strength relation is very favourable), engines, cables and cans. Aluminum is a good reflector and is therefore applied in solar mirrors and heat reflecting blankets. Aluminum is processed to cans, wiring and alloys.
Aluminum salts are often added to water to start precipitation reactions for phosphate removal. Consequently, sewage sludge in water purification with a pH value between 6.8 and 7.3 is present as hydroxides.
Alums are applied as fertilizer in tea plantations. Other aluminum compounds are applied in paper production. Alloys such as duraluminum are applied because these are stronger than aluminum itself. Aluminum foam is applied in tunnels as soundproofing material.
Other examples of aluminum application include aluminum chloride use in cracking processes, aluminum oxide as an abrasive or for production of inflammable objects, aluminum sulphate use as a basic material in paper glue, tanners, mordants and synthetic rubber, and aluminum hydrogen as a reduction and hydration agent.
Aluminum occurs as an aerosol in oceanic surface layers and in waters. This is because aluminum dust end up in water. Particles end up in water through surface run-off or atmospheric transport.
Generally, aluminum concentrations increase with increasing water depth.
