WebOzone layer protects the earth's surface from harmful UV rays of the sun. Ozone is formed through the interaction of solar ultraviolet radiation with molecular oxygen. Chemicals that damages Ozone. The chemicals used in refrigerators and air conditioners damages the ozone layer when released in the air, are CFCs or Chlorofluorocarbons. WebDec 7, 2009 · The word “aerosol” is used by scientists to mean “atmospheric particulate”. But it was used a lot by the media during the 1980s and 1990s to refer to the spray cans that released chlorofluorocarbons (CFCs) into …
WebThe ozone layer in the stratosphere shields the Earth from most of the Sun's ultraviolet radiation. Most of the chlorine in the Earth's stratosphere is from industrially produced chlorofluorocarbons. In the atmosphere, the chlorofluorocarbons are broken down by ultraviolet light into their constituent parts -- one of which, chlorine, destroys ... WebThe main causes of ozone depletion or formation of ozone hole are manufactured chemicals, especially halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).
