Uses of Oxygen

Natural Use
1. All living organisms, including animals or human needs Oxygen for respiration, which is usually found in the surrounding air. The process is named as Aerobic Respiration.
2. Atmospheric Oxygen O2 is helpful to support combustion but is not a combustive gas itself.

Mechanical and Industrial Use
1. Supply of Oxygen packed in cylinders aid people who have trouble breathing due to inadequate amount of Oxygen. For example- Patients in hospitals, Mountaineers at high latitude, Under water divers, astronauts walking in space etc.
2. The combustive property of Oxygen is used to produce energy automobiles, ships, generators etc.
3. Liquid Oxygen is used in burning fuel in spacecrafts for generating required thrust in space where there is either air or oxygen.
4. Oxygen is used in the following industrial applications- Steel Manufacturing, Chemical Processing, Pulp and Paper, Metal Production and Fabrication, Glass Manufacturing and Petroleum Recovery and Refining.
5. Oxygen is used to convert coal to electricity for power generation.
6. Oxygen is used in Oxy-Acetylene torch. The Oxygen makes the flame more hotter.

Some Compounds of Oxygen and their uses
Ozone is a well known compound of Oxygen. It is almost like Oxygen but it has an extra Oxygen atom. That's why, its sometimes called trioxygen. due to having more than two atoms, Ozone is much less stable than Oxygen. Ozone in the lower atmosphere pollutes air, causing problems of breathing for animals and burning sensitive plants. Therefore, Ozone exists on the upper atmosphere where it prevents damaging sun rays to reach us.


Some Machines and Process that uses Oxygen
The most known process that Oxygen is used in, is Oxygen Therapy. Its a kind of operation that is  used extensively all over the world. What this operation does is supplies human body with extra Oxygen. This kind of Therapy is usually used for a lot of emergency breathing problems. The most common one is acute Asthma or Pneumonia. 
Oxygen is used in Hyperbaric chambers. Hyperbaric chambers are usually used in Oxygen Therapies. It's also used when deep sea divers suffer from Oxygen shortage.
Some of the most often used Oxygen powered objects are for instance-Aircraft Emergency Oxygen System. This system is simply an air tight bag filled with purified Oxygen that is to be used during aircraft emergencies over normal latitude and atmosphere. There are other smaller version of Oxygen sprayers, almost like an EpiPen, but much more easier to use. These small Oxygen containers don't make a real difference during big emergencies but they do provide a refreshing effect after a long day's walk. (Oxygen containers containing 100% pure Oxygen is sometimes bad for your heart and lungs, so don't blame me if you end up having a heart disease due to immense consumption of purified Oxygen!!)


What are some positive impacts of Oxygen on Society?
Oxygen is something we are used to breathing form the very first day we were born. While we all need to sleep or drink to survive, the most basic and simple work like breathing and filling our lungs with oxygen is the most important necessity of life. As the number of population increase every single day, the amount of plants decrease, decreasing the level of Oxygen too. This may not seem like a big problem but within 10 or 20 years, Oxygen may turn into a rare gas, and if that happens, it would immediately diminish Humankind. Thus, Oxygen may be the most important thing on Earth. We should try to conserve it.

The Good and Bad of Ozone

Ozone is produced when three instead of two oxygen atoms (O3) combines. Its an unstable and highly reactive form of Oxygen. From our perspective, Ozone is both useful and harmful for us.


Benefits of Ozone


  • Ozone is found in Stratosphere which is part of the earth's upper atmosphere. At that level, Ozone helps us immensely by absorbing the extremely dangerous ultra-violet ray of the sun.
  • Without Ozone we would have turned sick as soon as we came in contact with our skin. We would have got skin cancer, cataract etc. our crops would have been damaged. And it would have killed specific marine life.
Risks of Ozone
  • The man-made Ozone that forms in the troposphere is extremely toxic and corrosive.
  • people who inhale Ozone during repeated exposure may permanently damage their lungs or suffer from respiratory infections.
  • Ozone exposure may reduce lung function or aggravate respiratory condition like asthma, emphysema or bronchitis.
  • Ozone may also cause chest pain and coughing.
Overall, its better to stay away from direct contact with Ozone in the atmosphere, because its as harmful as helpful Oxygen is.

Health hazards of Sulfur Dioxide (SO2)


Sulfur Dioxide is a moderate to strong irritant. Sulfur Dioxide when consumed, usually just penetrates the nose or throat, whereas it doesn't reach the lungs. Sulfur Dioxide only reaches lungs when a person is breathing heavily in chemical air filled with sulfur dioxide, or he is breathing it only through his mouth.
But when the sulfur dioxide concentration is extremely heavy in a particular closed space, SO2 can cause severe health diseases related to our lungs and air passage. Some such severe situations are-Hypoxemia, Pulmonary Edema and may even cause death in minutes. Severe exposure may cause permanent lung disease.
Skin contact with SO2 can cause irritation, liquid SO2 can cause burns due to freezing. Affected area will have numbness, prickling and itching. Blistering and Gangrene may occur. Exposure to SO2 without eye protection can cause severe corneal burns and could even damage the nerves in the eye. Sulfur Dioxide is one of those Oxygen compounds that are extremely harmful for human. One interesting fact about SO2 is that its the major component on the gas that is emitted from a volcano!!

How many compounds can Oxygen create?

Uranium Oxide: One of the rare compounds of Oxygen
The question that how may compounds Oxygen can make is almost impossible to find out. Suppose you have a periodic table, and you can see all the elements in it. Now try pairing up each of these elements with Oxygen and see if actually a compound like that exists. For example- suppose you choose calcium and pair it up with Oxygen, making a compound that may sound like Calcium-oxide. Now, if you research, you will find out that a compound like that actually exists. Almost all the elements in the periodic table can pair up with oxygen. Even the most rarest of element like Neodymium, can pair up with Oxygen and form the compound Neodymium sesquioxide or ND2O3. Oxygen can literally pair up with everything. That's one of the many unique characteristics of Oxygen.

Can Oxygen be harmful?

Did you ever think about Oxygen being harmful? Probably not. So, now I will reveal a very astonishing fact about Oxygen. Even though Oxygen is our daily necessity, it could be as harmful as helpful it is. Oxygen could be toxic at elevated partial pressures which could lead to convulsions or other health problems. In the past, premature babies were put into incubators containing enriched O2 air, but this practice was discontinued after some babies turned out to be blinded because of the excess Oxygen. Oxygen is a very sensitive gas. It must always be balanced in the atmosphere. Slight increase or decrease in the Oxygen level could turn out to be catastrophic in some situations. Oxygen toxicity could occur in the lungs or central nervous system in deep scuba diving and surface supplied diving. But we need not be worried about the toxicity of Oxygen in our day to day life as our atmospheric oxygen level is equally balanced.

Finale

Sadly, nothing goes on forever. and the same rule applies to me. Even if you like this blog a lot, I must stop now. Well, don't be sad. I may come back again, with a whole new topic, and whole new inspirations. But before I go, it would be a breach of manners to not mention the names of the websites that helped me write this awesome blog. So, lets look at the bibliography before we move on to a second blog.
