Released Into The Atmosphere Sulfur Dioxide
1,318 wordsEvery thing present in this universe is a part of environment including ourselves. Whether they are animals, living thing, or nonliving things. All of the external factors affecting an organism. These factors may be other living organisms (biotic factors) or nonliving variables (abiotic factors), such as water, soil, climate, light, and oxygen. All interacting biotic and abiotic factors together make up an ecosystem. Organisms and their environment constantly interact, and both are changed by th...

Chlorofluorocarbons Cfcs Nitrogen Oxides
1,336 wordsDramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970 's by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica from a research station. The Halley Research Station BAS research stations in the Antarctic Rumor has it that when the first measurements were taken in 1985, the drop in ozone levels in the stratosphere were so dramatic that at first the scientists thought their instruments were defective....

Road Salt And The Environment
1,465 wordsAs awareness for pollution increases, other less noticed types of pollution are recognized. Almost everyone knows about toxic waste and carbon dioxide pollution, but not many people have heard of salt pollution. Salt pollution has been on the increase since the evolution of the automobile. With more pressure on government agencies to keep the highway clear and safe, an increase in the use of salt has developed. It is important to understand why salt is used and how it work as well as the environ...

But what I think Dr. Landscheidt is are saying is that it does not need to be dealt with so fast because the planet will cool down more. So we can do it slower and spend less money on it. But we do not know if the greenhouse effect will overpower the natural effects. Unfortunately, this scenario of normal raise in temper...

Efflux pumps are what microbes use to rid themselves of toxic materials and drugs. The way science is perusing this is to attach these pumps with compounds called efflux-pump inhibitors. These compounds have no infection fighting power but can make current antimicrobial drugs more effective (Christensen). Microbes that caused sickness in the pre anti...

Ozone Molecules Ozone Depletion
1,052 wordsThe beginning of the CFC (chlorofluorocarbons) era started in 1928, when CFC' were invented by a Du Pont chemist. CFC' were best known as "freon's" and became famous as a safe, nonflammable refrigerant. It's invention became a great triumph when Freon took the place of sulfur dioxide or ammonia which was used as the working liquid in refrigerators. It eventually became widely used in automobile air conditioners and nontoxic propellants in aerosol cans. It's insulating properties also was used fo...

History Of Chemical Warfare
1,920 wordsHistory of Chemical Warfare The introduction of chemical warfare can be attributed to German chemist Fritz Haber who played a leading role in the development of poison gas during World War One. After much convincing he persuaded the Central Powers (i. e Germany, Turkey, etc. ) to use chlorine gas to break through enemy lines. The Germans awarded him with an Officers rank and he went on to direct the first gas attack in War history. This attack which occurred on April 22, 1915, was the first of n...

Greenhouse Gases Ultraviolet Radiation
421 wordsDiscovery of the hole in the ozone layer showed that human activity has a major impact on Earth. The destruction of ozone in the stratosphere high above the planets surface has been brought about as the result of the widespread use of chemicals, which under normal conditions are chemically inert and harmless. Ozone occurs at all levels in the atmosphere, but most of it is found in the stratosphere, between about 15 - 50 kilometres above the Earths surface. Even there it occurs in minute concentr...

Ozone Layer Ultraviolet Rays
962 wordsThe Problem The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the suns ultraviolet radiation to reach the Earths surface. In particular, it will be the increase of UV-B rays which will have the...

Natural Greenhouse Effect Greenhouse Gases
1,722 wordsWhat is global warming, and how is it affecting the Earth and its inhabitants? Global Warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earths surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the coming decades. For the last 10, 000 yea...

457 wordsThe Ozone Layer Ozone layer depletion slows There is good news about the ozone layer above us. The good news about the ozone layer is not always frequent. On International Ozone Day, the report came in that the ozone levels have decreased above Montreal and other residents of southern Canada. The ozone levels have decreased to a normal level. Normal meaning the levels have dropped from the levels reported in 1980. The ozone layer is an important and fragile part of earth. If we did not have an o...

1,498 wordsThe reappearance of the ozone hole over Antarctica has been a hot topic for scientist around the world. A few of these scientists are the atmospheric physicist Richard D. Mc Peters and several of his colleagues at the NASA Goddard Space Flight Center in Greenbelt. The ozone hole showed up earlier than expected, and it was wider and thinner. It appeared in mid-August, about two weeks ahead of schedule, and on September 19 reached the record size of 10. 5 million square miles, more than three and ...

Stratospheric Ozone Ozone Layer
2,496 wordsThe Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40 km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400 nm, are not affected by ozone. UV-C rays between 200 and 280 nm, are absorbed by the other atmospheric constituents besides...
