Key Concepts

International Environmental Policy

In response to the threat of ozone depletion, the global community adopted the Montreal Protocol, an international treaty aimed at phasing out the production and use of ozone-depleting substances. This agreement has been instrumental in reducing emissions of harmful compounds and promoting the recovery of the ozone layer.

Catalytic Destruction Mechanism

Once released, chlorine and bromine atoms catalytically destroy ozone through a series of chemical reactions. A single atom can break down many ozone molecules by initiating a cycle where it reacts with ozone to form chlorine monoxide and oxygen, and then is regenerated to continue the cycle, leading to significant ozone loss over time.

Stratospheric Ozone

The stratospheric ozone layer is a region of the Earth's atmosphere that contains a relatively high concentration of ozone (O3) molecules, which absorb most of the Sun's harmful ultraviolet radiation. This protective layer plays a crucial role in shielding living organisms from UV damage.

Ozone Depleting Compounds

Compounds such as chlorofluorocarbons (CFCs), halons, and related chemicals are primarily responsible for ozone depletion. These substances contain chlorine and bromine atoms that, upon breakdown by ultraviolet radiation in the stratosphere, are released and interact with ozone molecules.
