Interpretation:
The health effects of ground-level ozone as an air pollutant should be identified.
Concept introduction:
Ozone is a colorless gas having chemical formula O3. Ground-level ozone is not released directly in the atmosphere. It results from the reaction of oxides of nitrogen and volatile organic compounds when sunlight is present. The reaction is said to be photochemical reaction.
Interpretation:
The health effects of depletion of stratospheric ozone should be identified.
Concept introduction:
Ozone is a colorless gas having chemical formula O3.Stratosphere ozone also known as ozone layer, where concentration of ozone is high as comparison to other regions. Stratosphere ozone layer is present 20-50 kilometers above the Earth’s surface. This layer is important as it prevents the high energy UV radiation from reaching the Earth’s surface.
