Recent PhD Research Study: Ozone layer act as a shield to the stratosphere of Earth that is used to absorb most of the UV rays of the Sun. It’s found above 35 kilometers from the Earth’s surface. The layer was discovered by French physician Charles Fabry and Henri Buisson. Ozone means gas made of 3 atoms of oxygen that will represent as O3. The ozone concentration in the ozone layer can minimize. It’s the essential layer for the survival of living things on Earth. Since it absorbs biological harmful UV rays that will emit from the Sun. UV waves are divided into three types: UV-A, UV-B, UV-C. In this essay writing, we are going to see about the adverse effects of UV rays ant its cause.
The most harmful wave is UV-C which causes severe damage to living things. UV-B causes skin cancer and genetic damage to all living things. UV-B radiation with 290nm wavelength is screen out by Ozone. Even though some of the UV-B rays enter the earth’s surface, causing the skin problem. UV-A radiation can allow the earth’s surface among the ozone layer.
Particularly, this radiation is less harmful to living things. But still, there will be some effects like premature aging of the skin and physical damage — layer thickness changes from one place to another. In fact, the layer appears thinner over the equator, and it seems thinner over the poles. Thickness indicates the amount of ozone in that layer. But the thickness various from season to season.
Damage of Ozone layer
The depletion of this layer is because of solvents, propellants, halocarbons, and foam – blowing agents. Such as chlorofluorocarbons, HCFCs, halons are often called as ODS, which means Ozone Depletion Substances. Chlorofluorocarbon and bromine combine to with UV rays to destroy ozone molecules, chlorine atom destroys 1,00,000 ozone molecule. In this way, 4% of the ozone molecule gets destroy. At the same time, the depletion of the layer is mainly over Antarctica, and Australia is primarily because of the climatic condition. The chlorofluorocarbon emitted from driving cars, fridge, Air Conditioner is the leading cause of Ozone depletion.
The adverse effect of Ozone Depletion
In order to, increases the radiation of UV waves at the Earth’s atmosphere. The increase of UV rays causes skin cancer, eye cataract problem, and blindness. Especially, it also affects the living plants and animals adversely.
The solution to avoid depletion of the ozone layer
In Recent PhD Research Study, the ozone layer is crucial for the survival of living things on Earth. Nowadays the researchers are working to develop hydro fluorocarbon instead of hydro chlorofluorocarbons and chlorofluorocarbons utilize Air conditioners and vehicles. Inspection of Refrigerated and AC appliances to avoid and minimize leakage. Know more about: Mystery of Black Hole.
