Air Pollution – Causes, Effects and Sources of Air Pollution

Introduction to Air Pollution:

Air pollution refers to the presence of pollutants or pollutants in the atmosphere beyond the tolerance limit that can cause health problems for all people on earth. Causes of air pollution can be both natural and man-made. Air pollutants are mostly gases or small particles suspended in the air for a very long time.

Sources of Air Pollution:

The most characteristic sources of air pollution have always been combustion processes in which the pollutant is smoke. Among all combustion processes, the most dominant player responsible for pollution is automobiles. Burning fossil fuels in cars releases enormous amounts of sulfur and nitrogen oxides, which are heavy air pollutants.

Besides cars, the electricity sector is another important polluting game. Humans still depend on fossil fuels for all their energy needs. Coal is the main source of energy for generating electricity in thermal power plants and is the most polluted of all fuels. Burning coal produces smoke containing pollutants, and when this smoke is released into the atmosphere, these pollutants remain suspended in the atmosphere for a long time.

Air Pollution Scenarios:

Smoke has been the cause of urban air pollution for centuries for the same reason. Over the centuries, the use of coal has caused cities to be very smoky places. The current scenario is not much different. Coal is still burned in large quantities to generate electricity worldwide and is therefore one of the main sources of pollution.

The world has now shifted to liquid and gaseous hydrocarbons such as oil and natural gas to meet energy demands. Although these fuels are much cleaner than coal, excessive use of these fuels creates carbon monoxide, nitrogen oxides, etc. in the atmosphere. increased the concentration of greenhouse gases such as

Effects of Air Pollution:

Pollutants have a wide range of effects, and health issues are of the most concern. Respiratory diseases are at the top of the list of health problems. The second major health problem is heart diseases caused by the increase in the amount of carbon monoxide in the air. Pollutants also play a role in increased cases of Asthma, Eye Irritation and a number of bronchial diseases.

Pollution also affects our environment and ecosystems. Acid rain is the result of an increase in the amount of pollutants in the atmosphere that dissolve with rainwater. This acidic rain has seriously damaged our natural environment and ecosystem. Is the fading glow of the Taj Mahal, one of the seven wonders of the world, an example of how air pollution can affect our environment?

Air pollution control:

The need to control pollution was recognized in the first cities. The nineteenth century saw a growing interest in improving public health by controlling pollutants. Laws were created to keep pollutants downwind or out of town.

Since then, as environmental awareness has grown, many measures have been taken by governments and strict pollution laws have been introduced to industries to control pollutants. Advances in technology and the increased energy efficiency of engines have also helped reduce emissions compared to a few decades ago.
