Ozone is life threatening if found to be increasing near the earth’s surface as it is toxic to life when inhaled. Ozone not only damages airways, but also reduces crop yields as well if it increases beyond the threshold levels. Worries are mounting as India marks a rate of increase of around 1 per cent each year. Anthropogenic sources of emissions are responsible for increase in surface ozone, which needs urgent control in the near future.
The discovery of ozone (O3) in the troposphere was first made in the 1840’s. Consequently, an intensive study about its distribution was made in the latter part of the nineteenth century due to its supposed health-giving properties as a germicide (Schönbein, 1840). The first classical explanation of ozone in the troposphere was that it was made in the stratosphere by direct photolysis of oxygen at wavelengths less than 242 nanometer. Stratosphere is a layer above the earth’s surface, between approximately...
