Describe the Causes and Consequences of Ozone Depletion

The volcanic eruptions are also responsible for the depletion of the ozone layer. Each spring the Antarctic ozone hole causes a thinning or depletion of ozone in the stratosphere above the Antarctic.

Health effects arising from ozone air pollution include difficulty in breathing and pain in deep breaths.

. But it does not cause more than 1-2 of the ozone layer depletion. The ozone layer has been found to be depleted by certain natural processes such as Sun-spots and stratospheric winds. All the activities are done by human beings.

UV -C is absorbed by the oxygen in the atmosphere and never reaches us. Human activity has damaged this protective layer of the stratosphere and while ozone layer. The Antarctic ozone hole has been increasing in size.

CFCs generally dont react but only react with sunlight when it breaks down to release chlorine. Causes Effects and Prevention Dec 07 2021 뜀 Ozone layer depletion is the deterioration of the upper atmospheres ozone layer. Ozone depletion gradual thinning of Earth s ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities.

It is an unstable gas with a pungent odour it is bluish and it is located in two parts of the atmosphere. This year the slogan for World Ozone Day is Ozone For Life. That some ozone depletion might have oc-curred even apart from natural fluctuations.

The stratosphere and the. They are quite durable and can sustain harsh conditions. Through which the chemicals are made that contain chlorine or bromine.

The main potential consequences of this ozone depletion are to increase in UV-B radiation at ground level. Causes of Ozone Layer Depletion According to the studies done by the scientists the cause of the ozone layer depletion is human activity. The resulting colder stratosphere emits less long-wave radiation downward thus cooling the troposphere.

The ozone layer acts as a natural filter absorbing most of the suns burning ultraviolet UV rays. CFCs released from households and in-dustrial sites gradually rise to the stratos-. Up to 10 cash back Cataracts skin cancer and high-intensity sunburns are all on the rise in these countries due to ozone depletion and therefore higher exposure to harmful UV rays.

UV -B a higher energy form causes the most damage to living organisms and materials. Personally I have found very little disagreement among atmospheric researchers on major causes of Ozone depletion. The thinning is most pronounced in the polar regions especially over Antarctica.

Furthermore some scientists suggest that because of cold stratospheric conditions in the tropics they like polar regions could potentially suffer from severe ozone depletion. Ozone can cause coughing sore throat and chronic pulmonary diseases. These compounds release chlorine and bromine on exposure to high ultraviolet light which.

Continuous exposure to UV radiation affects humans animals and plants and can lead to skin problems ageing cancer depression of the immune system and corneal cataracts an eye. These are basically called ODS that stands for Ozone-Depleting Substance. 6 rows Ozone Layer depletion is the significant decrease in the concentration of ozone in the upper.

Human activity is the major factor in tipping that natural balance mostly from releasing artificial chemicals known as ozone-depleting substances ODS to the atmosphere. Ozone Depleting Substances ODS. The ozone layer is a form of oxygen in the molecular form of O3.

CFCs are generally composed of carbon fluorine and chlorine. There are two opposing effects. The main causes of ozone depletion or formation of ozone hole are manufactured chemicals especially halocarbon refrigerants solvents propellants and foam-blowing agents chlorofluorocarbons CFCs HCFCs halons referred to as ozone-depleting substances ODS.

This occurs when chlorine and bromine atoms in the atmosphere react with ozone destroying the. A modelling study has shown that the observed poleward expansion of the Hadley circulation is caused mainly by anthropogenic forcings such as increasing GHGs and stratospheric ozone depletion rather than by natural forcings. The depletion of our ozone layers and the creation of the ozone hole has occurred since the 1980s and it s only getting worst.

There are many causes for ozone depletion but the most important process in both trends is catalytic destruction of ozone by atomic chlorine and. Stratospheric ozone depletion leads to an increase in UV -B that reach the earths surface where it can disrupt. Conversely ozone depletion represents a radiative forcing of the climate system.

A one percent loss of ozone leads to a two percent increase in UV radiation. One of the major causes of ozone layer depletion is the chemical chlorofluorocarbons or CFCs. Damage to human health.

If the ozone layer is depleted humans will be overly exposed to strong UV light. The Earths ozone layer ozone layerThe region of the stratosphere containing the bulk of atmospheric ozone. Effects of Ozone depletion.

10 It was found that the effect of ozone depletion is dominant in the austral spring and summer for the southern cell but less. Stratospheric chlorine is at present the major catalyst of ozone depletion. Depletion of this layer by ozone depleting substances ODS will lead to higher UVB levels which in turn will cause increased skin.

The gas can aggravate conditions of the lungs such as chronic bronchitis asthma and emphysema. Overexposure to strong UV light causes skin cancer cataracts sunburns weakening of immune system and quick aging. World Ozone Day 1 5 World Ozone Day is observed on September 16 every year to spread awareness among people about the depletion of Ozone Layer.

The ozone layer lies approximately 15-40 kilometers 10-25 miles above the Earths surface in the stratosphere. Reduced ozone causes the stratosphere to absorb less solar radiation thus cooling the stratosphere while warming the troposphere. Since this area is considered a little more contriversial I have referenced it more heavily.

One chlorine molecule has the capability to break down thousands of ozone molecules. CF 2 Cl 2 UV light CF 2 Cl Cl. Ozone Layer Depletion 2 5 The Ozone layer reduces harmful UV radiation reaching.

Exposures over an extended period lead to lung damage and abnormal. Major and minor sources of stratospheric chlorine. The presence of chlorine and bromine from ozone depleting compounds in the stratosphere as well as the peculiar weather circumstances above Antarctica cause this harm.

Ozone depletion occurs when the natural balance between the production and destruction of ozone in the stratosphere is tipped in favor of destruction.
