Barium-TR

Barium is made up of the earth’s abundance. It contains a lot of different chemicals. It’s usually formed in Industries and factor that deal with coal and other mining items. The compounds of barium are use in plants flower rubber fireworks and much more. It can be found in water, dust, air, and other resources. It’s used in all countries. It may cause vomiting, diarrhea or other symptom of that cause.

As far as health, it depends on how much your affected to how much your infected by it. Some sides affects are vomiting, diarrhea, cramps, difficulties in breathing, increase or decrease in blood pressure, muscle weakness, or much more. The EPA has set the limit

BACKROUND
My topic is about silver metal that’s made up of 0.05% of the earth’s abundance, called Barium. Barium combines with a lot of different chemicals and elements, such as sulfur or carbon and oxygen. All theses combinations are forms of numerous barium salts. Half of the salts are freely soluble in water, and other are in soluble.

The Barium combinations and compounds are use in various areas, such as oil and gas industries. They are used in those industries to make drilling mud’s. These compounds are also used in paints, bricks, tiles, grass rubber, depilatories, fireworks, and ceramics. In the medical field, Barium is used for medium contrast for taking radiographs of the gastrointestinal. Barium salts is also sold as rodenticides. Also barium can be exposed in air from the industrial working facilities. Also, barium can be found in dust and in Brazilian nuts (which are high in barium).

Barium is not banned in any countries, but it is not registered for use in a range of different countries. The benefits and downfalls of barium is that it may cause vomiting, diarrhea, increase or decrease in blood pressure, numbness around the facial area, and much more. Also, if barium is drunken then its possible for irregular heart beats to occur, and possibly death.

Synthesis/ Production
Barium is silver metal that’s made up of 0.05% of the earth’s abundance. A thin film of barium titanate is formed on a substrate by immersing the substrate in an aqueous solution. This contains barium ions and titanium alkoxide. Some common products that contains barium is water, coal, and its also in factories and industries. They end up in factories and industries, because when people are working on the refining and production of coal, barium forms. Its forms from water in the same way as it forms in industries, except its transfer from throughout the air and into drinking water. Some balanced chemical reactions of the chemical and its compounds are BaSO4 + 4C => BaS + 4CO, and BaSO4 + 2CH4 => BaS + 2C + 4H2O, and 4BaO + 2Al => 3Ba + BaO*Al2O3. Barium sulphate is the white crystalline solid. It’s insoluble in water and other potential solvents. Barium sulfide is the chemical compound that goes by the formula BaS. This material was once known as "Bologna Stone", the first synthetic phosphor. Barium peroxide is a grey white compound and oxidizing agent. It’s used in fire works as a color changer.

Barium has many different health affects and symptoms. Sometimes it depends how much barium goes into your body. The affects are gastrointestinal disturbances and muscular weakness. This is when people expose there self to more then the EPA drinking level. If you eat or drink even small amounts of barium may experience vomiting abdominal cramps, diarrhea, difficulties in breathing, increased or decreased blood pressure, n umbness around the face, and muscle weakness. When you give yourself large amounts of barium you may experience.

The EPA has set the limit to only 2.0 percent of barium into drinking water. Food and water are the two most common exposures to barium. The Department of Health and Human Services and the International Agency for Research on Cancer haven’t yet classified barium to be carcinogenicity. This is only if barium ingested in humans, but if inhaled then it could be considered a carcinogenicity to humans

Environment
Barium interacts with the environment in many different ways. Barium can get into the air during mining, refining, the burning of coal and oil, and other production of barium compounds. Also fish and other aquatic organisms can accumulate barium. Barium compounds such as Barium Chloride, Barium hydroxide, and Barium Nitrate doesn’t dissolve easily in water. These compounds usually don’t last to long in these forms.

The barium compound that does dissolve in water includes sulfate and/or carbonate that are naturally found in water. Them water compounds become the longer lasting forms. The length of barium that last in air, land water, or sediments depends on different forms of which barium is released. Barium sulfate degrades after being exposed to moisture.

Economic/Political Impact
If barium weren’t here a lot of thing would be affected. For example, barium nitrate makes the green signal flares and, green fire works, so there would not be too much of them colored fire works if barium was banned. Also if barium were banned there would be less diarrhea incidents, vomiting and stomach cramps, and heart problems, because barium (when exposed to into the air, food, and water) can cause these symptoms.

The costs of water and other products that barium could be exposed to aren’t that high in price. For example, a case of water these days that was probably process and filtered in a factor, that had barium lurking around, is very cheap now days. All countries and cities use barium. Barium isn’t banned in any countries in the world. Like I said before, it would affect simple things, if barium were to be ban ever.

Summary
The cost are of barium aren’t’ high in price. Since barium is in water, air, and food it’s easy to get now a days. For example a case of water doesn’t cost much, and faucet water is free with a house. Also, air is free, and food is cheap today too. So there for barium isn’t hard to get around the community, and everyone can be exposed to it.

The good thing about barium is that some of the compounds of barium make green signal flares and fireworks. Green signal flares are good in case of emergencies. So you wouldn’t want not to have them. Although if there was no barium there would be less vomiting and muscle weakness and stuff like that. So barium has its ups and downs.
