CFCs are generally composed of carbon fluorine and chlorine. Cause effects and solutions on Business Standard.

35 Causes Effects Solutions For Ozone Depletion E C

Although natural phenomenon can cause ozone depletion but human activities such as CFCs are now accepted as major cause of depletion 9.

. Exposures over an extended period lead to lung damage and abnormal development of. Global Effects of Ozone Depletion Ozone depletion in the earths atmosphere is under constant scrutiny by the American press and people. 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.

This causes more ozone to be destroyed than created causing a hole in the ozone that allows the suns harmful ultraviolet rays to Get started for FREE Continue. Essay on OZONE DEPLETION BY HUMANS ACTIONS. Furthermore some scientists suggest that because of cold stratospheric conditions in the tropics they like polar regions could potentially suffer from severe ozone depletion.

The nitrogenous compounds are also the reason behind the depletion of the ozone layer such as NO NO2 and N2O. For example cloud cover can decrease or increase the intensity of UV radiation at Earths surface and warmer temperatures and changes in precipitation patterns may alter the amount of time people spend outdoors and their choice of clothing. A steady lowering of about four percent in the total amount of ozone in Earths atmosphere and a much larger springtime decrease in stratospheric ozone the ozone layer around Earths polar regions.

Ozone depletion occurs when the natural balance between the production and destruction of stratospheric ozone is disturbed. It implies that the rate at which the Ozone is being destroyed is much faster than the rate at which it is being formed. Ozone is not the same as the oxygen humans breathe.

Credible scientific studies have substantiated that the cause of ozone layer depletion is human activity specifically human-made chemicals that contain chlorine or bromine. Make it more difficult to breathe deeply and vigorously and cause pain when taking a deep breath. Inflame and damage the.

Causes of Ozone Depletion. Ozone is a hot slightly bluish gas. Other ill-effects of the reduction of protective ozone layer include increase in the incidence of cataracts sunburns and suppression of the immune system.

CFCs released from households and in-dustrial sites gradually rise to the stratos-. The gas can aggravate conditions of the lungs such as chronic bronchitis asthma and emphysema. First off lets begin with a definition of the ozone layer.

Stratospheric ozone depletion leads to an increase in UV -B that reach the earths surface where it can disrupt. Furthermore the ozone depletion is affecting the aquatic life biogeochemical cycles air quality and also contributing in Global warming but in this review paper our main focus is on the effects of ozone depletion on human health 1. 10 It was found that the effect of ozone depletion is dominant in the austral spring and summer for the southern cell but less.

The thinning is most pronounced in the polar regions especially over Antarctica. The ozone layer is a very important component in the atmosphere. These are released by solvents spray aerosols refrigerators air-conditioners etc.

UV -C is absorbed by the oxygen in the atmosphere and never reaches us. Ozone Layer depletion is the significant decrease in the concentration of ozone in the upper layer of the atmosphere caused due to the reaction of chemical compounds containing chlorine and bromine. Read more about Ozone layer depletion.

The latter phenomenon is referred to as the ozone hole. One of the major causes of ozone layer depletion is the chemical chlorofluorocarbons or CFCs. These compounds release chlorine and bromine on exposure to high ultraviolet light which.

Ozone can cause coughing sore throat and chronic pulmonary diseases. This radiation release chlorine atoms react with the ozone layer and cause depletion. Depending on the level of exposure ozone can.

Various studies have been undertaken to find out possible solutions. Cause coughing and sore or scratchy throat. Ozone Depletion is the effect of the CFCs on the ozone layer.

1992 Sep127 Suppl 412-6. Ozone depletion occurs when the natural balance between the production and destruction of ozone in the stratosphere is tipped in favor of destruction. The major cause of blindness in this world is cataracts.

Ozone depletion is a major environmental problem because it increases the amount of ultraviolet UV radiation that reaches Earths surface which increases the rate of skin cancer eye cataracts and genetic and immune system damage. The ozone layer depletion is also caused due to some natural processes such as stratospheric winds and. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.

There is very little of this gas in the atmosphere. Environmental Protection Agency 2006. Causes of Ozone layer depletion.

Ozone depletion consists of two related events observed since the late 1970s. Ozone layer depletion first captured the attention of the whole world in the latter half of 1970 and since then a lot of research has been done to find its possible effects and causes. The ozone layer protects life on earth by absorbing 97-99 of the damaging ultraviolet radiation from the sun US.

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 leads to wheezing and shortness of breath. Ozone depletion and its effects on human populations Br J Dermatol.

UV -B a higher energy form causes the most damage to living organisms and materials. CF 2 Cl 2 UV light CF 2 Cl Cl. On World Ozone Day have a look at the various causes effects and solutions of.

Climatic factors affect the amount of UV radiation received by the skin and eyes separately from the effect of ozone depletion. Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. 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.

Ozone can cause the muscles in the airways to constrict trapping air in the alveoli. Perhaps the concern is warranted. CFCs generally dont react but only react with sunlight when it breaks down to release chlorine.

They are quite durable and can sustain harsh conditions. Author R R Jones 1 Affiliation 1 St Johns Dermatology Centre St Thomass Hospital London UK. There are also springtime polar.

That some ozone depletion might have oc-curred even apart from natural fluctuations. The ozone layer acts as a natural filter absorbing most of the suns burning ultraviolet UV rays.
