'Effects of CClF3 on Ozone\r'

'CC13F to enter the stratosphere (1930 to 1955). 2. The ozone storey above Canada began to decline in 1975. 3. Once the takings of CC13F was drastically reduced, it took 20 years for the CC13F levels to decrease in the stratosphere. Conclude and Communicate 4. CFCs (Chlorofluorocarbons) are inorganic artificial chemicals that have been in production for more than 50 years in Canada.They were thought to be lurid substances due to their stability, nonflammable characteristic, low in toxicity, and inexpensive. However, look into on CFCs showed that they have long life spans allowing them to dare being washed away in rain. through the aid of wind, CFCs rise up into the stratosphere and into the ozone form where they fail into atomic number 17 and bromine, from the ultraviolet radiation. These two chemicals are obligated for damaging the ozone layer.Some atmospheric chlorine are caused by natural occurrences such as large fires and volcanic eruptions, yet most chlorine in the oz one layer is due to CFCs from man-made products such as refrigerators, aerosols, solvents and new(prenominal) household items. Studies show that for every one hlorine pinpoint that is released into the ozone layer, 100000 ozone molecules are destroyed. According to the statistics recorded in 1979, the ozone layer has decreased every single ten dollar bill nearly 4% to 6% in mid-latitudes and 10% to 12% in higher southern latitudes.This unbroken decrease has left the ozone layer permanently damaged. sluice though production of CFCs has drastically decreased over the past couple of years, the ozone layer is unable supervene upon itself. Research on how Earth is affected by the depletion in the ozone layer 5. CFCs are so lasting that the only way to break them is by movie to strong UV radiation. When this occurs, the CFC molecule releases chlorine that can destroy 100000 ozone molecules.\r\n'
