  • Depletion Of The Ozone Layer - 1,052 words
    Depletion of the Ozone Layer Depletion of the Ozone Layer CHEM 151 Research Paper July 11, 1996 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 research on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitr ...

  • Man And The Ozone - 1,120 words
    Man And The Ozone Man and the Ozone Ozone is perhaps one of the singularly most important molecules there is. No, not because man came from ozone, but because it forms a protective layer above the earth in it's stratosphere which allowed for the growth of life upon land. Before we had an ozone layer, the rays of the sun struck the earth unimpeded, barraging it with the deadly ultraviolet radiation which prohibited any chance of life on earth. However, there was life in the oceans, plant life in particular. This plant life may seem unimportant, especially since it is algae that is being given the spotlight. The algae in the ocean produces oxygen gas (O2), which would rise through the water an ...

  • Ozone - 983 words
    Ozone annon Ozone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earth's surface. The dioxide molecule, O2 and Oxygen atom O, collide with each other result in the formation of Ozone, O3. In this reaction, the molecule O3 contains an excess of energy. Once the molecule is formed, it is not stable enough to last long. The energy-rich O3 molecules discards the excess energy by colliding with another atom or molecule and transferring the energy in the form of heat. In the results of the decomposition of ozone into O2 and O in the ozone layer, solar radiation is absorbed. ...

  • Ozone Depletion Is An Environmental Problem That Many People Do Not Take As Seriously As They Should The Ozone Layer Prot - 1,074 words
    Ozone depletion is an environmental problem that many people do not take as seriously as they should. "The ozone layer protects animal and plant life from the sun's harmful radiation. The depletion of the ozone layer will allow ultraviolet rays to, over time, lead to higher skin cancer rates, eye cataracts, and crop damage." At ground level, ozone, a form of oxygen, is poisonous to humans and other organisms. It causes respiratory problems and damages plants. The greatest concentration of ozone is located in a layer of air called the stratosphere, some 10 to 30 miles above the Earth's surface. About 90% of the Earth's protective ozone layer resides in this level. "The molecule, ozone, is pro ...

  • Ozone Layer - 1,860 words
    Ozone Layer Some scientists have proclaimed that the human race is slowly depleting the layer of ozone which protects us from ultra violet light. In reality, humans have very little control of the world in which we live. Scientific evidence has shown that there is very little depletion in the ozone layer and the contributions the human race makes towards this depletion is and always will be insignificant compared to nature. The theories of the depletion and what it would cause are flawed and contradictory. Where and when did this global killing threat begin? It all began in the mid 1960's when the United States government began pursuing super sonic transports. These would be planes which wou ...

    Ozone Layer Depletion The Potential Effects of a Depleted Ozone Layer And God said, let there be light and there was light and then God saw the light, that it was good ( Genesis 1: 3-4 ). Undoubtedly, light is good. Without light man could not survive. Light is the ultimate cosmic force in this universe allowing man to progress and flourish. In the form of heat, light from the sun warms the Earth. Light, also, is the single most important factor influencing the growth and development of plants. Photosynthesis, a process by which plants incorporate light from the sun, allow plants to botanically grow and survive. Certain forms of light are harmful and thus can be said are 'bad'. A natural umb ...

    ... re available to man, than being mostly confined to polar water regions, another principal food resource could be added to man's long list of them. Another important feature involved in a decline in phytoplankton numbers and productivity is the fact that phytoplankton helps produce and recycle the world's oxygen supply ( Bowermaster et al, 1990, p.40 ). An increase in ultraviolet light can thus endanger an entire ecosystem without necessarily killing off the masses. By altering the respiratory balance in an ecosystem a variety of species would be affected. Furthermore, the same oxygen recycled by phytoplankton is breathed by all animals and man himself thus adding to the importance of the ...

  • Ozone Layer Poisoning - 1,109 words
    Ozone Layer Poisoning The poisoning of the Earths ozone layer is increasingly attracting worldwide concern for the global environment and the health effects of life on the Planet Earth. There is not just one particular cause for the ozones depletion; the accumulation of different pollutants into our ozone layer has all added up and equaled a worldwide problem. There is not just one effect from the poisoning of the ozone, but instead multiple ramifications from diseases to death. The damage to the ozone is increasing with every second; moreover, there are many ways we can help reduce the problem and preserve the ozone layer. Ozone is a pale blue gaseous form of oxygen, in chemical form it is ...

    ... diation could get so high that it may start burning trees and eventually forrests, in the process destroying our sources of oxygen that we need to survive. The increase in radiation will start to diminish crops and other food sources. Starting with the depletion of the ozone layer, the domino effect of the extinction of biological systems on Earth would continue to plants and then on to the marine ecosystem. The effects of poisoning of the ozone layer will lash out on the marine ecosystem. The marine ecosystem would severely suffer from the thinning ozone and the increase exposure to ultrviolet radiation. Starting with phytoplankton, the foundation of acquatic food chains, would loose th ...

Plausible mechanisms include heterogeneous chemistry on sulfate aerosols [which convert reservoir chlorine to active chlorine - R.P.] and the transport of chemically perturbed polar air to middle latitudes.

  • Ozone Regulations - 1,336 words
    Ozone Regulations In 1997 the Environmental Protection Agency (EPA) established new ozone standards. The EPA also placed special restrictions on twenty-two states in the Ohio Valley and Midwest regions to prevent emissions from coal-burning power plants from being carried into the New England States by wind currents. (Tennessee is one of these twenty-two states.) Both of these rulings were recently either struck down or placed on hold by Federal Appeals Courts. Why: The regulations put into place in 1997 by the EPA were more restrictive than the 1990 standards. The regulations limit the amount of ground level ozone and fine particle pollution permitted. Ground level ozone is produced by nitr ...

  • The Ozone - 1,107 words
    The Ozone The Ozone Ozone derives from the greek word ozein which means to smell. It was first discovered in 1839 by Christian Friedrick Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O2. This is why ozone isharmful. Ozone always wants to let go of its third compound, and if this compound reacts with other substances, it could be damaging, especially to humans. When discussing with the ozone ...

    Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases. Many people believe that this issue is too small to deal with right now, and others believe it should be met head on. In the following paragraphs I will be discussing the impact of acid rain effects on wildlife and how our atmosphere is being destroyed. Causes Acid rain is a cancer, eating into the face of Eastern Canada and the North Eastern United States. In Canada, the main sulphuric acid sources are non-ferrous smelters and power generation. On both sides of the border, automobiles are the main sources for nitric acid (about 40% of the total). Power generating plants, industrial com ...

  • Acid Precipitation - 663 words
    Acid Precipitation Acid Precipitation Our atmosphere functions as living ecosystem of chemical reactions. Through the help of the water cycle, chemicals pass through the atmosphere and are eventually taken up by the soil, surface water, or organic materials. Human beings have added enormously to the atmospheric burden of many toxic substances. The most prominent evidence of this is the presence of acid rain: precipitation and particles that have been made acidic by air pollution. Acid rain is a direct consequence of the atmosphere's self-cleansing process. The tiny droplets of water that make up clouds continuously capture suspended particles and soluble trace gases. Not all trace gases can ...

Osmoregulation is the process of maintaining the delicate balance of salts and minerals in their tissues. For freshwater fish, maintaining osmoregulation is key in their survival. Acid molecules, which are a result of acid rain in the water, cause mucus to form in the fishs gills. This in return prevents the fish from absorbing oxygen. If the fish are unable to absorb oxygen, the consequence could be the eventual suffocation of fish and the low pH could throw off the balance of salts in the fish tissu ...

    Acid Rain Acid Rain is caused by pollution containing sulfur dioxide, nitrogen oxide, and ozone ( SO, NOx, and O ) is released into the air. These chemicals are absorbed into clouds and results in Acid Presipitation ( Acid Rain, Acid Snow, Acid Hail, Acid Sleet ). When the chemicals aren't absorbed into clouds, they can drift for miles and fall to the ground, resulting in Acid Deposition, or dry deposition. When Acid Rain falls into water it is mixed in with the normal water and causes the pH of the entire body to be raised. Measurments on the pH ( potential Hydrogen ) scale, rise exponentialy, thus, a lake with a pH of 4 is ten times as acidic as a lake with a pH of 5, and a lake with a pH ...

  • Acid Rain - 1,774 words
    Acid Rain What is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. These particles partly dissociate to produce hydrogen ions and bicarbonate ions ...

  • Acid Rain - 1,731 words
    Acid Rain Introduction: What Causes Acid Rain? One of the main causes of acid rain is sulfur dioxide. Natural sources, which emit this gas, are Volcanoes, sea spray, rotting vegetation and plankton. However, the burning of fossil fuels, such as Coal and oil, are largely to be blamed for approximately half of the emissions of this gas in the world. When sulfur dioxide reaches the atmosphere, it oxidizes to first form a sulfate ion. It then Becomes sulfuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Oxidation occurs the most in clouds and especially in heavily polluted air where other compounds such as ammonia and ozone help to catalyze the reaction, changing ...
