The 4 Main Types of Pollution and Their Causes


Hassam loves researching and writing about all kinds of subjects, including pollution and the environment.

This article will examine the four main types of pollution and their causes.

This article will examine the four main types of pollution and their causes.

The term pollution refers to the act of contaminating one's environment by introducing certain hazardous contaminants that disturb the ecosystem and directly or indirectly affect the living organisms of that ecosystem. Pollution in general is the activity of disturbing the natural system and balance of an environment.

The increase in the pollution by humankind over the years has caused severe damage to the earth’s ecosystem. It is responsible for global warming, which is leading to the end of all the lives on earth. Over the years, there is an extreme increase in the rate of human diseases, and death rate of various animals and plants on earth, and that is all because of the pollution caused by humans.

There are many types of pollution, but four of them have the most perilous effects on our lives. This article will take a brief look at four of the most dangerous types of pollutions and their causes.


Air Pollution

Air pollution is perhaps the most common and the most dangerous type of pollution. It involves the direct release of chemicals into the environment. The chemicals then become the part of the air around us that all the living things take in.

The increase in the rate of diseases such as asthma and lung cancer today is due to the increase in the air pollution around us. Air pollution is also a cause of global warming and acid rain.

Causes of Air Pollution

Basically, the air pollution is caused by the burning of fuel that directly releases hazardous chemicals into the air. For example, the burning of coal releases sulphur dioxide, a poisonous gas that is responsible for acid rain.

The main sources of such chemicals are large factories and smoke from vehicles, chimneys, and the burning of wood.


Soil Pollution

Soil pollution involves the contamination of soil by the release of harmful substances into the ground. Unlike air pollution, which has a direct effect on human lives, soil pollution causes indirect damage to humans and other animals.

The lives of all the living things depend on four sources: water, air, light, and soil. The plants which that the producers of the food chain take up their nutrients—which are essential for their living—from the soil.

The nutrients taken by the plants are then transferred to the consumers that depend on these plants. Hence a soil consisting of contaminants will not only affect the plants growing on the soil but it will also indirectly harm the entire food chain.

Causes of Soil Pollution

Soil pollution is mainly caused by the release of industrial waste. This waste is directly incorporated into the soil by large industries and factories. Soil pollution is also caused by human acts as mining and deforestation etc.

Water Pollution

More than 75% of the earth’s surface is covered with water and more than half of the total population of earth’s species reside in water.

Moreover, our life greatly depends on water, and life without water is impossible. Water pollution not only affects the fish and animals living in the water but also affects the whole food chain by also transferring the contaminants to the consumers depending on these animals.

Water used from a polluted lake directly contaminates its user. Many of the planet's water creatures are on the verge of extinction due to the dramatic increase in water pollution.

Causes of Water Pollution

Just like air and soil pollution, water pollution is caused by the direct incorporation of hazardous pollutants.

The sources of these pollutants are yet again predominantly the fault of large industries and factories that dispose of their waste in lakes and ponds.


Noise Pollution

Unlike the other above mentioned types, noise pollution does not involve hazardous chemicals or their incorporation into the environment. Rather, noise pollution is the increase in the rate of noise in the environment.

Noise is defined as an unpleasant sound that has an adverse effect on the ear. Noise can be extremely dangerous, and it is all around us. It penetrates into the human mind and controls it.

Too much noise leads to severe psychological illness and badly affects the behavior. It can lead to hypertension, stress, aggression, and annoyance. Moreover, it can cause depression and forgetfulness.

Aggressive sounds can also disrupt the lives and mating patterns of various animals and wildlife.

Causes of Noise Pollution

Noise pollution is largely caused by moving vehicles, manmade machines, and loud music. Other than that, noise can be caused by anything, but these three sources are the main reasons for the noise pollution around us.
