The Implications of Ozone Depletion on Human Health Essay examples --
The Implications of Ozone Depletion on gracious Health entry Hairspray. Refrigerators. Air conditioners. These all(prenominal)day luxuries, while making charitable life more(prenominal) comfortable, be taxing our health seriously. Clorofluorocarbons, or CFCs, are anthropogenic chemicals employ in refrigerants and as propellants in aerosols. CFCs, also cognize as freons, are also the primary culprit behind the depletion of stratospheric ozone, which allows insalubrious ultraviolet rays to stretchiness the Earth and its inhabitants.When CFC molecules reach the stratosphere, the suns radiation sickness sickness breaks it apart, press release the chorine share to destroy ozone molecules. The effect is a growing ozone pickle which forms over Antarctica in October and usually lasts through mid November. During the annual ozone hole, the quantity of UV radiation that reaches the Earth can double. Ozone depletion serves as a major(ip) health endangerment for human beings. The three primary health effects of ultraviolet radiation on human health are ill-treat to the skin,eyes, and immune system. undress DAMAGEUV radiation causes significant rail at to human skin, in the form of sunburns, aging, skin cancer, and nonmelanoma tumors. Human skin rail at is primarily a resoluteness of tanning. Theamount of UV exposure imprisoned by a person is a direct result of the inspiration of the light absorbed, the distance of time of the exposure, and whether or not the skin was harbored by vestments or sunscreen. Skin footing can be prevented by narrowing when and how long one is exposed to sunlight, and by tiring protecting(prenominal) garment and sunscreen. Avoid exposure to sunlight during mid-day hours, when it is most intense. tight-fitting weave clothing, and hats, protect against the suns rays. Tanning beds, while popular, are also ... ...ening diseases. Conclusions Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. wizard American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are straightway being use in the place of CFCs that will not damage statospheric ozone, and there is world(prenominal) recognition of the importance of developing these chemicals. The Montreal Protocol is an outside(a) treaty which limits the turnout of ozone depleting substances. Still, human health is at risk from the omission of ozone, and the risk chemical element will continue to rise unless people and industries develop more awake(predicate) of the implications connected with everyday use of chemicals which destroy stratospheric ozone. The Implications of Ozone Depletion on Human Health Essay examples -- The Implications of Ozone Depletion on Human HealthIntroduction Hairspray. Refrigerators. Air condi tioners. These everyday luxuries, while making human life more comfortable, are taxing our health seriously. Clorofluorocarbons, or CFCs, are anthropogenic chemicals used in refrigerants and as propellants in aerosols. CFCs, also known as freons, are also the primary culprit behind the depletion of stratospheric ozone, which allows harmful ultraviolet rays to reach the Earth and its inhabitants.When CFC molecules reach the stratosphere, the suns radiation breaks it apart, freeing the chorine atom to destroy ozone molecules. The effect is a growing ozone hole which forms over Antarctica in October and usually lasts through mid November. During the annual ozone hole, the amount of UV radiation that reaches the Earth can double. Ozone depletion serves as a major health risk for human beings. The three primary health effects of ultraviolet radiation on human health are damage to the skin,eyes, and immune system. SKIN DAMAGEUV radiation causes significant damage to human skin, in the f orm of sunburns, aging, skin cancer, and nonmelanoma tumors. Human skin damage is primarily a result of tanning. Theamount of UV exposure absorbed by a person is a direct result of the intensity of the light absorbed, the length of time of the exposure, and whether or not the skin was protected by clothing or sunscreen. Skin damage can be prevented by limiting when and how long one is exposed to sunlight, and by wearing protective clothing and sunscreen.

Conclusions Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
