Air Contamination

Air Contamination:        A silent threat to living entities

Air contamination is a type of pollution that plays a crucial role in the impurities spreading in our environment. When the air that surrounds us becomes contaminated, it is referred to as air pollution. There are various reasons of air pollution, and some major causes are discussed below.

Causes Of Air Contamination:

Industries & Factories:

An important reason for the excessiveness of air pollution is industries and factories. In the processing of raw materials, the combustion of fossil fuels, and the extraction of metals, harmful gases and chemicals such as carbon dioxide, nitrous oxide, methane, sulphur dioxide, or fluorinated gases are released extensively, significantly polluting the air.


Deforestation is the process in which plants and trees are cut down for various reasons, such as for land, agriculture, and constructing buildings. Plants and trees inhale carbon dioxide and exhale oxygen, but when deforestation occurs, the stored carbon dioxide in these trees is released, becoming a cause of air pollution. Additionally, when forests are cleared, the remains of decomposing animals release harmful gases into the air, contributing to pollution. Deforestation also leads to the extinction of species, further impacting the environment, and is a significant cause of global warming and climate change.

Natural sources:

Natural sources of air pollution are causes that do not result from human activities but naturally pollute the environment. Examples include dust storms, which occur naturally due to the absence of rain or dry soil conditions, and these storms can pollute the air,and when we inhale that air so it becomes the reason of several diseases.

Sea spray is another element introduced into the air when there are high waves in the ocean or sea, containing droplets with aerosols, viruses, minerals, and salts. Aerosols are tiny particles that contribute to climate change, global warming, and air pollution, even affecting rainfall rates. Additionally, natural sources include volcanic eruptions and biogenic emissions.Volcanic eruptions are also a natural source of polluting the atmosphere. In a volcano burst, gases, lava, and ash are released, leading to the emission of various harmful gases such as carbon dioxide, sulfur dioxide, and others into the air. The mixture of these substances can result in the formation of harmful elements like acid rain.

Agricultural activities:

Engaging in agriculture is beneficial as it provides us with crops and vegetables. However, when people conduct improper agricultural activities, it leads to an increase in pollution. For instance, the use of fertilizers in agriculture releases Volatile Organic Compounds (VOCs), which, when mixed with the air, increases ozone gas at ground level, posing harm to human health. Additionally, the burning of crop residues in many agricultural sectors releases carbon dioxide, contributing to air pollution. Furthermore, certain machines and tractors used for harvesting in agriculture also contribute to air pollution.

Burning of garbage:

Another significant cause of air pollution is when people, instead of properly disposing of their accumulated garbage, choose to burn it. This common practice releases harmful gases, bacteria, and viruses into the air, thoroughly polluting the atmosphere.

Vehicle emissions:

When we look at the roads, we see vehicles everywhere – buses, cars, motorbikes, autos, taxis, trucks, and tractors. We must have observed how much smoke and exhaust fumes are emitted from these vehicles. In these emissions, there are many harmful gases like carbon monoxide, nitrogen oxides, and hydrocarbons. Then, particulate matters are released from vehicle exhaust, causing various diseases.

Effects Of Air Contamination:

The planet we inhabit, Earth, is covered by the atmosphere and air. When this air and atmosphere contain a high concentration of harmful gases and chemicals, it has a severe impact on human health. The effects of air pollution on human health include:

  • Respiratory infections
  • Heart diseases
  • Lung cancer
  • Strokes
  • Asthma
  • Shortness of breath
  • Coughing
  • Chest pain
  • Eye irritation
  • Premature deaths
  • Cardiovascular diseases
  • Impact on pregnant women

Solutions Of Air Contamination:

The primary cause of the increasing air pollution is human activities, indicating that we are polluting our environment and, as a result, falling victim to serious diseases. Now, it is up to us humans to do everything possible to decrease air pollution.

One solution is for industries to adopt clean and green technologies. The government needs to impose strong emissions regulations to control smoke effectively. Additionally, promoting the use of electric vehicles is crucial as they emit no smoke. If arranging electric vehicles in the short term is not feasible, we should minimize our use of vehicles and encourage the use of bicycles, benefiting not only the environment but also our physical health.

For those who burn garbage, designated disposal areas should be established near their locations to make it easy for them to dispose of garbage properly. Furthermore, awareness campaigns should be conducted to educate people on how harmful burning garbage is to the environment.


So, we have studied this crucial type of pollution, air pollution or contamination, and how it is caused, how it is polluting our air, and the impact it has on our health and the health of other living things. After that, what responsibility do we, as humans, have in addressing this issue? How is air pollution mostly caused by human activities? Now, in our surroundings, we need to do everything possible to stop this pollution.
