Question

In stratosphere which element act as catalyst in degradation of ozone

Answer 1

Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine andbromine) in the stratosphere can be calculated and are known as the equivalent effective stratosphericchlorine (EESC).
