Ozone is a highly reactive and unstable form of oxygen that is present in small concentrations in both the stratosphere and the troposphere. It plays an important role in the atmosphere, resulting in both beneficial as well as detrimental effects on both living and non-living things. The stratospheric ozone protects the living beings and the environment from the harmful rays of sun, whereas the troposphere ozone or ground level ozone is highly toxic for living beings and is notorious for causing material damage and corrosion. The ground level ozone usually results due to the interaction between atmospheric pollutants and the sunlight, though a small amount is also contributed from the overlaying stratosphere. The concentration of ozone varies from one place to another and within the same environment from time to time. However, with an increase in population and rapid industrialization, the concentration of ozone has been gradually increasing over the past few years. This ozone, being a powerful oxidant, often leads to significant material damage, resulting in economic losses due to increased cost of production and maintenance. The ozone climatic test chambers are often employed by industrial units and research organizations to study the effect of ozone exposure on the aesthetics and functional value of various products, including plastics, rubber, paint, fabrics, metals etc.
