EFFORTS TO REDUCE OZONE IN SOUTHERN CALIFORNIA Team A SCI/362 June 29, 2011 Kenneth Rayford “EFFORTS TO REDUCE OZONE IN SOUTHERN CALIFORNIA” The Los Angeles Basin is a plain that lies between the Pacific Ocean and mountains to the north and east. During the summer, the sunny climate produces a layer of warm, dry air at upper elevations. Southern California counties are where almost 15 million people reside. South Coast Air Quality Management District (SCAQMD) is a governmental organization

circumstances, objects, or conditions by which one is surrounded. Acts against the environment causes the ozone layer to deplete. The ozone layer is defined as a region of the upper atmosphere containing relatively high levels of ozone, located mostly within the stratosphere. The ozone absorbs large amounts of solar ultraviolet radiation, preventing it from reaching the Earth's surface. When the ozone layer is depleted, it caused the greenhouse effect, a slowdown of the rate at which the earth loses heat

Montreal Protocol: An effective tool for controlling ozone depletion? INTRODUCTION For centuries, human activity has been altering the natural environment. Science has been preoccupied by how these changes affect the earth's natural support system and the impact that might have on life form, particularly man. The effects of most human activities are more or less fully understood, from the contribution of pollution to global warning, to the link between deforestation and the advancement of the

Du Ponts Strategy Analysis The postulation by Mario and Sherry in 1974 proved that the CFCs led to externalities associated with the ozone layer. They projected that the continued use of CFCs around the world led to a daily decrease in the ozone layer leading to the creation of the “ozone hole”. The sales of CFCs, especially in the USA, declined drastically as consumers became more cautious since they were aware of the impact of the CFCs on the environment. In addition, the government enforced

outgoing heat radiation and reradiate it back towards the surface. -Ozone depletion is also one the causes of global warming. Plummeting ozone levels in the stratosphere over Antarctica during September and October are the result of complex chemical processes. The return of the Sun at the end of winter triggers photochemical reactions that lead to the destruction of ozone in the stratosphere. There are some natural means that effect ozone like volcano eruptions, and drastic changes in weather problems

The ozone layer is a specific area in the stratosphere of maximum ozone concentration. Ozone in the stratosphere forms naturally and protects us from damage that can be caused by solar radiation such as skin cancer. In the 1970s chemists discovered that certain chemicals could travel into the upper atmosphere and damage the protective ozone. Ever since this was discovered scientists, government, and citizens have been making efforts to control and reverse the damage done to the ozone. In 1987 a treaty

Running Head: OZONE DEPLETION Taylor Graham Ozone Depletion The Ozone Layer The ozone layer prevents most harmful solar ultraviolet light, (UV) from passing through the earth’s atmosphere by absorbing 93-99% of these UV rays. UV rays are potentially damaging to life on earth. The ozone layer is comprised of high concentrations of ozone, (03) and mainly located in the lower portion of the stratosphere (rabbitair.com). The atmosphere of the Earth is divided into 5 layers. From closest

investment in improving the tree canopy. Trees are one of the few elements of our infrastructure that increase in value over time. Trees remove air pollutants, alter microclimates, and reduce air temperature. Tree also absorb and filter water, cool our homes and business and increase property value. They are known to reduce stress, aggression and asthma rates and increase the livability and vitality of our neighborhoods and businesses. A tree canopy is the percent of a city’s land area that has tree

as refrigerants, aerosols, and plant factory emissions affect the status of the ozone layer in the atmosphere? HYPOTHESIS: CFC strongly contributes to the depletion of the ozone layer in the atmosphere. OBJECTIVES: * To measure the amount of CFCs release from refrigerants, aerosols, emissions of factories and other products and materials that contain CFCs. * To determine the degree of CFCs in the ozone layer. * To quantify the percentage between different elements and chemicals

and government agencies alike on embracing as well as understanding environmental issues is rapidly growing around the world. Could it be because of the hundreds of pictures being shown of the ice melting in the Arctic or the increasingly depleting ozone later or simply because the suave Al-Gore has managed to convince us with his Inconvenient Truths? It could be any one of these global reasons or it could just be due to a personal experience that directly impacted your life. The fact is that the awareness
