Answer» CFCs are widely used refrigerants. They are discharged in lower parts of atmosphere but however more upward and reach the stratosphere where UV rays act upon them releasing chlorine atoms which degrade ozone releasing molecular oxygen. CFCs added to stratosphere in this way have permanent and continuing effects on ozone. Therefore, it is suggested to reduce its emission as far as possible. |
