Sources of air pollution - Essay Example

What will happen if the temperature of the world increases? Global warming will occur. Global Warming is prevalent on our Earth even today. It is causing deaths of thousands of animals each year, glaciers are melting and the pollutants are causing diseases such as asthma and lung cancer, etc. The destruction of ozone layer is continuously taking place by our activities, the use of natural resources by us and also by emissions of harmful gases in the atmosphere. At first, we will look into the sources of air pollution inside our homes.

We, as human beings are a major constituent of creating air pollution. In our offices, schools, and homes, we make use of certain products and perform activities which are the reason for air pollution. Such activities are known as anthropogenic sources of air pollution. These activities include cooking and smoking. Other sources comprise of Boilers in which we boil water or other liquids at our homes, steam generators as they create smog when we start them for electricity purposes. Also piston engines, furnace, and gas turbines create pollution in the air1.

Also, industrial plants set up by humans, power plants and vehicles which have internal combustion engines generate VOCs, nitrogen oxides, carbon dioxide, carbon monoxide, sulfur dioxide and their particulates. In most big cities and urban areas of the world, cars are the primary source of these air pollutants such as Los Angeles and Mexico City2. Farmers burning wastes from crops create carbon dioxide, carbon monoxide and other particulates. Other human activities such as leaky refrigerators, aerosol sprays, perfumes and fumes from varnish, paint, and other solvents are the main factors in increasing air pollution.

Natural sources, also known as biogenic sources, are also a cause for air pollution but are not as harmful as the human sources. The quality of air is destroyed or worsened by natural processes such as volcano eruptions which produce chlorine, sulfur,
