ISSN: 2010-0264 Ozone Layer Depletion and Its Effects: A Review Sivasakthivel.T and K.K.Siva Kumar Reddy Abstract - There are many situations where human activities have significant effects on the environment. Ozone layer damage is one of them. The objective of this paper is to review the origin‚ causes‚ mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer. The chlorofluorocarbon and the halons are potent ozone depletors. One of
Premium Ozone depletion Ozone Ozone layer
The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer‚ also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man‚ animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there‚ the harmful ultraviolet rays will reach to the

• Depletion of ozone and formation of ozone hole • Ozone‚ in fact is a gas having fishy smell and O3 molecules which works as the protective shield for the life in the earth. It absorbs solar ultraviolet radiations and thereby protects life on the earth from several damage such as DNA mutation‚ skin cancer‚ blood cancer‚ etc. In the year 1985‚ NASA detected the thinning out of the ozone layer leading to the formation of ‘ozone hole’ in Antarctica. Since then the scientists have been regularly

Every time 1% of the ozone layer is depleted‚ 2% more UV-B is able to reach the surface of the planet. So in short‚ without the ozone layer everything on earth will burn. The ozone layer is just as important to us as oxygen‚ without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth‚ there are a few groups who think that the ozone layer is a “myth” aka doesn’t

Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while stratospheric Or‚ is decreasing. This decrease is called Ozone Depletion Ozone depletion deals with
Premium Ozone depletion Greenhouse gas Atmosphere
The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started

Ozone depletion and Volatile Organic Compounds Christina Stelmach SCI/ January 20‚ 2013 Christine Snyder The atmospheric issue that I chose to write about is the Ozone layer depletion and the indoor air pollutant is Volatile Organic Compounds. I am going to talk about the cause and effect of each of these issues and also efforts to mitigate the issues. Our Earth’s Ozone layer protects all life from the sun’s harmful radiation. Due to all human activities damage has been done to our

The ozone layer is a layer in Earth’s atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun’s high frequency ultraviolet light‚ which is potentially damaging to the life forms on Earth.[1] It is mainly located in the lower portion of the stratosphere The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist

OZONE LAYER DEPLETION AND GLOBAL WARMING OZONE LAYER DEPLETION AND GLOBAL WARMING. The ozone layer acts as a giant sunshade‚ protecting plants and animals from much of the sun’s harmful ultraviolet radiations. Ozone forms a layer in the stratosphere‚ 15-40 km above the earth surface. If the ozone in the atmosphere from the ground level to a height of 60 km could be assembled at the earth’s surface‚ it would comprise a layer of gas only about 3mm thick. Global stratospheric ozone
