Special Pollutant: Chlorofluorocarbons (CFCs) - Minnesota Pollution Control Agency
(UV-B) rays generated from the sun. There is a substantial amount of scientific evidence that suggests man-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere). Decreased concentration of stratospheric ozone allows increased levels of UV-B rays to reach the earth's ...

Why the banning of Chlorofluorocarbons is paranoia.
W. Pease From The Wall Street Journal, 23 March 1989, p. A24:3 The news earlier this month that several European countries and the U.S. have agreed to phase out the use of chlorofluorocarbons (CFCs) by the year 2000 brings before us yet again the questionable theory that CFCs cause depletion of the ozone layer. Atmospheric chemist F. Sherwood Rowland , of the University of California, Irvine, ...

Stratospheric Ozone Depletion tutorial
The decrease of stratospheric ozone was first reported in 1974 and the decrease was quickly linked to the increasing presence of a class of manmade compounds called CFC's or Chlorofluorocarbons. Many countries of the world have moved to reduce the use of CFC's but because of the slow rate of air mixing between the lower and upper atmosphere it is theorized that stratospheric CFC ...

Ozone: Good Up High, Bad Nearby
Layer? Ozone occurs naturally in the stratosphere and is produced and destroyed at a constant rate. But this "good" ozone is gradually being destroyed by manmade chemicals called chlorofluorocarbons (CFCs), halons, and other ozone depleting substances (used in coolants, foaming agents, fire extinguishers, and solvents). These ozone depleting substances degrade slowly and can remain intact for ...

In the atmosphere some of the long-wave radiation is absorbed by certain gases called greenhouse gases. These include carbon dioxide (CO2), chlorofluorocarbons (CFCs), methane (CH4), nitrous oxide (N20), tropospheric ozone (O3), and water vapor. Each molecule of greenhouse gas becomes energized by the long-wave radiation. The energized molecules of ...

(CSE) CoP-8/UNFCCC SPECIAL EDITION 1 October 23, 2002 Earth has a fever There naturally exist in the atmosphere gases such as carbon dioxide (CO2), methane (Ch4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), and water vapour. They are called greenhouse gases. Thats because they act like a blanket spread over the earths surface, helping to keep it warm. The temperatures experienced near the ...

Terms Beginning With "O"
This destruction of ozone is caused by the breakdown of certain chlorine and/or bromine containing compounds (chlorofluorocarbons or halons), which break down when they reach the stratosphere and then catalytically destroy ozone molecules. Ozone Hole: A thinning break in the stratospheric ozone layer. Designation of ...

COLLABORATIONS CSIRO AUSTRALIA Ozone depletion –This site is under review and will be replaced – Ozone depletion in the upper atmosphere is the result of human-produced chemicals, such as chlorofluorocarbons (CFCs) and halons. Depletion is especially severe over Antarctica in spring, causing the highly publicised "ozone hole". However, at all latitudes away from the equator, the layer of ozone ...
