They are classified as Halocarbons‚ a class of compounds that contain carbon and halogen atoms‚ and are amongst a group of substances called "greenhouse gases". They eat away at our ozone and raise the temperature of our planet significantly‚ causing detrimental damage to our planet. Chlorofluorocarbons (CFC’s) are a man-made substance that did not previously exist to the industrial area. They are a product of a collaboration of

The pollution in atmosphere has tendency to form their layers and sinks in atmosphere. The chlorofluorocarbons which come from aerosol sprays nuclear weapons‚ refrigerators etc.‚ have caused a hole in the ozone layer of atmosphere. This hole is allowing increased amount of ultraviolet radiation reaching our earth. The above mentioned factors have really degraded the environment and

Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays. Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons‚ hydro chlorofluorocarbons in the atmosphere. As ozone layer will go thin‚ it will emit harmful rays back on earth and can cause skin and eye related problems. UV

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

The Poisoning of Our Ozone Layer The poisoning of the Earth’s 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 ozone’s 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

and concrete. Ozone hole Other global concerns because of air pollution include the greenhouse gases and the hole in the ozone layer in the stratosphere. The Earth’s ozone layer is supposed to protect people from the Sun’s harmful ultraviolet rays‚ but in the 1970s‚ scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen‚ which means that more ultraviolet rays reach the Earth. During the 1980s‚ scientists found that the ozone layer above the South

Canticle For Leibowitz: Walter Miller Walter Miller‚ in the novel A Canticle For Leibowitz‚ mocks the way we are as humans‚ particularly in those ways that lead to regressive thinking. The novel pokes fun at the attention to impractical details‚ such as to the spent copying the Leibowitz blueprints. Miller also mocks humans by describing the inordinate amount of attention and energy given to a spiritual being such as Leibowitz‚ as today’s society worships God. Finally‚ the most absurd way
