Question

If there is a drop in the amount of ozone in the upper atmosphere Why does this drop occur?

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 and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

Answer 2

Answer:

Chlorofluorocarbons (CFCs) are responsible for the majority of observed stratospheric ozone depletion. Every spring over Antarctica, extremely cold conditions enable chemical reactions that produce very high levels of ClO, resulting in rapid ozone removal. Within the so-called "ozone hole," levels can drop to 85 DU.
