What Is Pollution? Types Of Pollution & Facts 2023



Pollution Definition: Pollution is a process that makes soil, water, air, or other parts of the environment dirty, unsafe, or unusable.

This can be done by introducing pollution into the natural environment, but the pollution does not have to be solid.

Simple things like light, sound, and temperature can be considered pollution when artificially inserted into the environment.

Weak pollution affects more than 200 million people worldwide, according to the non-profit environmental organization Pure Earth.

In some of the most polluted places in the world, children are born with birth defects. Children have 30-40 IQ points, and cancer and others can reach the age of 45.

6 Types of Pollution

1. Air Pollution

The air we breathe contains a delicate chemical composition. It contains nitrogen, oxygen, water vapor, and unsafe gases. Air pollution occurs when things that are not usually added to the air are added to the air.


A very common type of air pollution happens when people burn fossil fuel and release pollutants into the air. It’s like pollution, where millions of tiny particles float in the air.

Another commonly known form of air pollution is toxic gases, such as chemical fumes, carbon monoxide, sulfur dioxide, and nitrogen oxides.

They can participate in chemical reactions once in the environment, and produce acid rain and smoke. Other sources of air pollution can come from indoor buildings, such as smoke.

At last, pollution can take the form of harmful greenhouse gases, such as sulfur dioxide and carbon dioxide. These gases heat the planet via the greenhouse effect.

According to the Environmental Protection Agency, the greenhouse effect occurs when gases absorb infrared radiation from Earth, preventing heat from escaping.

It is a natural process that keeps our environment warm. However, if a lot of gas is introduced into the atmosphere, much heat is reserved, and as a result, the planet may be artificially heated, according to Columbia University.

According to a study published in the Environmental Research Letters, air pollution kills more than two million people every year. According to Hugh Sealy, the effects of air pollution on human health are widespread.

If the contamination is very toxic, the health effects may be widespread and serious. For example, a 1984 refusal to reject methyl isocyanate at the Union Carbide plant in Bhopal killed more than 5,000 people and caused more than 400,000 breathing difficulties.

Nuisance (such as particles less than 10) can cause respiratory disease, cardiovascular disease, and asthma.

Air pollution can be carcinogenic (for example, some VOCs) or biologically active (for example some viruses) or radioactive (for example, radon “Other pollutants, such as carbon dioxide, have indirect effects on human health through climate change.

2. Land Pollution

The domestic and industrial waste can pollute the land. According to the U.S. Environmental Protection Agency, in 2014, Americans produced nearly 258 million tons of solid waste.

More than half of the waste, 137 million tons, was collected in landfills. Only 35% were remanufactured or composted.

The Environmental Protection Agency said that organic matter is the largest waste component.

Paper and cardboard make up 27% of solid waste. Food and garden decor contribute to 16 and 13% waste. Rubber, leather, and textiles contribute nearly 10 percent. Metals 9.5%, and plastic nearly 13%. Wood contributed 7% to the waste. Glass representation was 5%.

Commercial or industrial waste is an important part of solid waste. According to the University of Utah, industries use up to 5 million pounds of materials to provide the average American family with a 1-year worth of products.

A large section is categorized as non-hazardous, such as medical waste (gloves, dressings surgical tools, discarded needles, etc.) and construction materials (concrete, wood, brick, glass, etc.).

Effective waste is any liquid, solid, or soil waste that contains potentially harmful or harmful properties to human health or the environment.

Industries produce hazardous waste from mining, oil refining, pesticides, and other chemicals. Effective waste is also produced in homes, such as paints, solvents, motor oil, fluorescent lamps, aerosol cans, and ammunition.

3. Thermal Pollution

Heating water can be harmful. The synthetic temperature of the water is called thermal pollution. This can happen when a factory or power plant that uses water to cool its work ends with hot water emissions.

Water retains less oxygen than this, which may kill fish and wildlife. A sudden change in body temperature of the water can also kill fish.

According to the University of Georgia, it is estimated that nearly half of the water withdrawn annually in the United States is used to cool power plants.

“In almost all cases, 90 of this water is returned to its own source, as the water may immediately warm up in an area just below the drain pipe.

Food contamination, also known as eutrophication, is another type of water contamination. This is when nutrients like nitrogen are added to water bodies.

According to NOAA, the nutrition acts as a fertilizer and makes algae grow at exorbitant rates. Algae is banned from other plants. Plants die and decompose oxygen in the water. The oxygen in the water kills aquatic animals.

4. Water Pollution

Water pollution occurs when harmful chemicals or foreign substances enter the water, including chemicals, sanitation, pesticides, fertilizers from leaking agricultural materials or minerals such as lead or mercury.

According to the Environmental Protection Agency (EPA), 46 river fairs, 66% of lakes and 32% of the Gulf and East are not suitable for hunting and swimming.

The Environmental Protection Agency also states that the most contaminated bacteria in the U.S. are bacteria, mercury, phosphorous, and nitrogen.

They come from the most common sources of pollution, especially from agricultural liquid wastes, environmental reservoirs, water diversion, and channeling waterways.

Water pollution is not a problem for the United States alone. As per the U.N, 780 million people have no access to clean water and almost 2.5 billion people have inadequate sanitation facilities.

Correct cleaning helps prevent wastewater and other pollutants from entering the water supply.

According to the National Marine and Environmental Administration (NOAA), 80% of water pollutants from the marine environment come from sources such as the Earth’s source.

Water pollution can seriously affect marine life. For example, dirty water causes pathogens to grow, while organic and inorganic compounds in water can alter the formation of valuable resources.

According to the Environmental Protection Agency, low levels of dissolved oxygen in water are also polluted. It dissolves by decomposing organic matter such as wastewater entering the water.

5. Noise Pollution

Even if humans cannot see or smell noise pollution, it still affects the environment. Noise pollution occurs when the sound of aircraft, industry or other sources reaches an effective level.

noise pollution

Scientific studies show that there are direct links between health and noise. These include speech difficulty, stress-related illnesses, hearing loss, and high blood pressure.

For example, a WHO team study on the environmental burden of noise indicates that increased rates of coronary heart disease can lead to noise pollution in millions of deaths annually. Under the Clean Air Act, EPA can regulate machinery and aircraft noise.

It has been shown that underwater pollution from ships disrupts the navigation system by wheels and kills other species that depend on the underground natural world, which also enhances wildlife from noise.

6. Light Pollution

Surviving without modern amenities and electricity seems impossible for most of the people.

However, the lights of the natural world changed the way light works day and night.
