Ozone hole - why is it increasing?

An ozone hole is a common name for the exhaustion of an ozone layer of 15-20 kilometers in the area of ​​the South Pole, which was first observed in the 1980s.
Ozone is an unstable form of oxygen. It spontaneously decomposes into molecular and atomic oxygen. It has the shape of blue gas with a pungent odor, has strong oxidative properties. In the air, it is harmful to living organisms and accumulates in the upper layer of the atmosphere. The ozonosphere is a layer of the Earth’s atmosphere between 20 km and 50 km, which protects the Earth from excessive harmful solar radiation.
The reasons for increasing the ozone hole are associated with emissions of freons. The compounds under consideration are used in many areas, including cosmetic industry and medicine. Freons are derivatives of halogenalcans. They contain fluorine and chlorine atoms. It can be without smell or with the smell of diethyl ether. They are not poisonous and not flammable. These are colorless gases that accumulate in the atmosphere. Under the influence of ultraviolet radiation, they decompose into carbon, fluorine and chlorine. The fluorine neutralizes itself, joining other atoms. Coal is burned, and chlorine accelerates the breakdown of ozone into ordinary oxygen molecules. As a result, there is an exhaustion of an ozone layer, known as an ozone hole. Galons and nitrogen oxides also contribute to an increase in the ozone hole. Galons are halogen derivatives and methane. They are non -toxic and non -combustible. They are used in the production of fire extinguishers. Nitrogen oxides are formed in the ozonifier as a result of fuel burning with rockets and aircraft. Their source is also nuclear explosions.
The ozone hole increases due to the release of the gases described above, in the course of a complex process of chemical reactions. Chlorine atoms are released from a decaying greenhouse gas molecule. They attack ozone, separating one oxygen atom. Thus, molecular oxygen O2 is formed. The relationship of chlorine with oxygen is unstable. The oxygen atom breaks and joins the ozone, forming two o2 oxygen molecules. The situation is aggravated by the fact that chlorine atoms remain active in the atmosphere up to 100 years.
The ozonosphere absorbs part of the ultraviolet radiation reaching the surface of the Earth from the Sun. Any loss of ozone causes the penetration of large doses of sunlight, which harms living organisms. Global warming is also a consequence of an increase in ozone hole. The problem was noticed in the 1980s. Then the first international actions were undertaken.
On the initiative of the UN program on the environment, representatives of more than thirty countries signed the Montreal Protocol. The 1987 Agreement involved the reduction of the production of chemicals that destroy the ozone layer by 2000 by 50%. Best porn noodlemagazine.com - Girls do porn.
