Q10: Why has an “ozone hole” appeared over Antarctica …

The severe depletion of stratospheric ozone in Antarctic winter is known as the “ozone hole” (see Q11). Severe depletion first appeared over Antarctica because atmospheric conditions there increase the effectiveness of ozone destruction by reactive halogen gases (see Q8). The formation of the Antarctic ozone hole requires abundant

Ozone depleting substances include a number of different compounds such as CFCs, HCFCs, and halons, all of which have global warming potentials. As mentioned, these ODSs are being phased out of production due to their ozone depleting properties. However, some entities may still use these substances directly or in blends within refrigeration, air

Rate of production of NO2 is faster when nitric oxide reacts with ozone in the stratosphere. NO (g) + O 3 (g) → NO2 (g) + O2 (g) The irritant red haze in the traffic and congested places is due to oxides of nitrogen. Higher concentrations of NO2 damage the leaves of plants and retard the rate of photosynthesis. Nitrogen dioxide is a lung
