Today is World Ozone Day. September 16 is known as International Day for the Preservation of the Ozone Layer.
That is why some important things to remember about Ozone Day as well as Ozone Gas and Ozone Layer.
Declaration of World Ozone Day
The United Nations General Assembly declared September 16 as World Ozone Day. It was published on December 19, 2000. This was officially recognized on the International Day for the Protection of the Ozone Layer, announced by the United Nations General Assembly in 1994. International Day for the Protection of the Ozone Layer Remembers the original Montreal Treaty on Ozone Layer Protection, signed in 1987.
The Ozone Layer
The ozone layer acts as a canopy in the stratosphere. It is the ozone layer that absorbs the harmful ultraviolet radiation from the sun and creates the ideal environment for life on Earth. Ozone layer absorbs 97% to 99% of the ultraviolet light at wavelengths between 200 nanometers and 315 nanometers. Scientists say that exposure to those rays can cause life-threatening damage.
The ozone layer is mainly found in the lower part of the stratosphere. That is, in the upper reaches of the Earth, 20 to 40 km away. The thickness of the ozone layer varies from time to time and geographically.
The ozone layer was first discovered in about 1913. The two French physicists were Charles Fabry and Henri Buisson. Later, various scientists conducted various experiments on the ozone layer. Meanwhile, the British National Meteorologist G.M.B. Dobson is outstanding. It was because he conducted a detailed study of ozone and revealed the properties of ozone.
Ozone layer formation
Scientists say there is a link between the formation of the ozone layer and life on Earth. The ozone layer of the atmosphere has not existed for about 4.6 billion years since the beginning of the earth’s existence. Therefore, ultraviolet rays, which are harmful to life, have no doubt reached the earth. Life is confined to the deepest parts of the ocean. The process of photosynthesis began about 600 million years ago. There is an opinion that ozone production has begun, since it began to receive oxygen.
The nature of ozone gas
Ozone gas is made up of three oxygen atoms. Oxygen is necessary for the human respiratory process. However, ozone, which is formed from three oxygen atoms, is harmful to the human respiratory system. Ozone gas is a light blue gas. It has a pungent odor. The amount of ozone in the atmosphere is about 0.000004%, and it varies from time to time.
Chemicals that damage the ozone layer
There are many chemicals that can damage the ozone layer. There are nitric oxide, nitrogen oxide, hydroxyl, atomic chlorine, atomic bromine. Scientists say the use of chlorofluorocarbon and bromofluoro carbon has increased in the recent past.
Works that damage the ozone layer
There are several ways in which ozone can damage humans. These include refrigeration and air conditioning, perfumery, paint, pesticide spraying, fumigation processes, use of fire extinguishers and cleaning agents among others.
The ozone hole
It was not until the late 1970’s that scientists noticed that ozone gas was thinning and creating a hole. It was first reported in 1985 that a hole was formed by the thinning of ozone in the sky over Antarctica. It was reported in 2003 that the ozone hole was the largest. At the time, it was about 29 square kilometers in size.
Consequences of damage to the ozone layer
When the ozone layer is damaged, harmful ultraviolet light reaches it. Ultraviolet rays can cause dryness of the skin, wrinkles, skin burns and skin cancer. Cataracts and blindness are another possible condition. Genetic mutations can also cause damage to the human immune system. Plants and animals can be damaged or destroyed. Ultraviolet rays reduce the yield of agricultural crops and cause climate changes.
