Air Pollution

We take 23,000 breaths per day. I’m at my house. I’m at work right now. You’re driving around in your car. You’re driving to work. That’s a lot of breaths.

Breathing is something that most of us don’t think about because we can’t see it. When you can’t see contaminants like invisible gases or particles, it’s tough to identify what’s in the air around you.

Most people are unaware that more than 90% of the world’s population breathes dirty air, according to the World Health Organization. This terrifying figure has an impact on everyone, especially children, the elderly, and asthmatics.

When you look at the causes of air pollution, you’ll notice that humans are the primary source of pollution. Industrialization is having both beneficial and harmful effects on humanity and the environment. Furthermore, one of the major drawbacks that we are suffering as a result of our actions is the rising rate of environmental degradation. We must first comprehend the meaning of air pollution before discussing its control.

Definition of Air Pollution

Pollution of the air, water, or soil by any chemical that is hazardous to living creatures is referred to as air pollution. It’s the same as introducing or releasing a dangerous chemical into the environment, which can destroy the environment’s elements. Pollution can occur due to both natural (such as volcanic eruptions) and man-made causes. However, man-made factors are currently creating more pollution than natural factors. Each contributes to air pollution in some way, from the expanding number of automobiles to the ever-increasing industrial wastes in the form of air or water.

What is the definition of air pollution?

According to the definition of air pollution, it occurs when any physical, chemical, or biological change occurs in the air and contaminates it. Many factors can pollute the air, including dangerous or harmful gases, smoke, fog, smog, dust, and so on. Air pollution has an impact on both plants and animals.

Pollutants in the Air

Primary and secondary pollutants are the two types of air pollutants. Pollutants are compounds that produce pollution in the air.

• Pollutants in the first tier:

The principal contaminants that produce air pollution are those that create pollution directly. Hazardous gases from manufacturers, such as sulphur dioxide, are among them. The pollutants that are formed as a direct result of the process are known as primary pollutants. A famous example of a main pollutant is sulphur dioxide, which is produced by factories.

• Secondary Pollutants (Secondary Pollutants):

The process of intermixing or intermingling of primary pollutants produces secondary pollutants. Smog is a secondary pollutant that is a mixture of fog and smoke.

Air pollution is caused by a variety of factors.

To reduce air pollution in the surrounding area, you must first comprehend the sources of air pollution. The key reasons for this are:

• Fossil Fuels: What Happens When They’re Burned?

Fossil fuels release toxic chemicals into the atmosphere, such as sulphur dioxide and carbon monoxide. Sulphur dioxide, which is emitted by the combustion of fossil fuels such as coal, petroleum for energy in power plants, and other industrial combustibles, is one of the most significant sources of air pollution.

• Automobiles:

Excessive use of autos results in the release of hazardous gases.

• Agriculture and activities:

Agricultural activities result in the release of ammonia, as well as the misuse of insecticides, herbicides, and fertilisers. Ammonia is a common agricultural waste and one of the most hazardous gases in the atmosphere. Insecticides, pesticides, and fertilisers have all grown more widely used in agriculture. They pollute water and discharge harmful chemicals into the atmosphere.

Farmers also set fire to fields and old crops to clean them out in preparation for the new sowing cycle. Burning to clean up fields, according to reports, pollutes the air by spewing hazardous chemicals.

• Factories and Businesses:

Increased industrial activity results in the release of hazardous gases and chemicals into the atmosphere. Manufacturing firms release a lot of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air, which degrades air quality.

Manufacturing industries can be found all throughout the world, and no place is immune to their influence. Hydrocarbons and a number of other pollutants are also released by petroleum refineries, causing harm to the air and soil.

• Activities in the Mining Industry:

Mining activities are increasing dangerous chemical emissions. Mining is the process of extracting minerals from under the earth’s surface with the help of heavy gear. Throughout the process, dust and chemicals are released into the air, leading to severe air pollution.

This is one of the reasons contributing to the declining health of the area’s workers and residents.

• Resources in the United States:

Effects of residential sources such as the abuse of air conditioners and the usage of chemical paints. Hazardous chemicals are released into the air by household cleaning goods and painting supplies, damaging the environment. Have you ever noticed that painting your house’s walls generates a foul odour that makes breathing practically impossible?

Suspended particulate matter, often known as SPM, is another source of pollution. SPM stands for suspended particulates in the air, which are often created by dust, combustion, and other reasons.

Air pollution-related diseases include:

In humans, air pollution can lead to an increase in diseases such as throat infections and lung cancer. Air pollution-related diseases kill and hospitalise millions of people every year. According to World Health Organization estimates, air pollution is responsible for one out of every eight deaths worldwide. The development of respiratory and cardiovascular illnesses has been linked to both outdoor and indoor air pollution, according to new studies. Among the most common disorders caused by air pollution are ischemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung cancer, and acute lower respiratory infections in children.

“Ischemic heart disease, or coronary heart disease,” Kevin Wood, Vice President Sales & Marketing at USA, explains, “is linked to calcium or other materials like fat deposition within the coronary artery.” “Blockages occur as a result of this, preventing blood from reaching the heart and other critical organs.” According to new research, air pollution accelerates artery blockage, raising the risk of ischemic heart disease.”

Air Pollution’s Consequences:

The data on air pollution reveals that increased pollution has negative consequences for plants, animals, and humans.

• Warming of the planet

Because the earth’s temperature continues to rise as a result of hazardous gas emissions, air pollution can exacerbate global warming. An impending crisis has already been warned by rising global temperatures, rising sea levels, melting ice from colder locations and icebergs, relocation, and habitat destruction if preservation and normalisation measures are not taken quickly.

• Rainfall that is acidic

Acid rain occurs when water droplets interact with toxic chemicals and contaminants. Harmful substances such as nitrogen oxides and sulphur oxides are released into the environment when fossil fuels are burned. When it rains, water droplets mix with impurities in the air, causing them to become acidic and fall to the ground as acid rain. Humans, animals, and agriculture are all at risk from acid rain.

• Depletion of the ozone layer

All of this will eventually result in the ozone layer, which protects humans from dangerous UV sun rays, being depleted. The ozone layer on Earth is being degraded by the presence of chlorofluorocarbons and hydrochlorofluorocarbons in the atmosphere.

Damaged rays are sent back to Earth when the ozone layer thins, potentially causing skin and eye problems. UV radiation can also cause damage to crops.

As a result, we must act to prevent air pollution.

• Animal Reactions

Increasing air pollution has an impact on animals and aquatic life, causing them to wander and stray in search of food. As a result, many animals are on the verge of extinction. Animals, sometimes known as wildlife, are especially vulnerable to the impacts of pollution in the air. Pollution problems include acid rain, heavy metals, persistent organic pollutants (POPs), and other hazardous substances.

Insects, worms, clams, fish, birds, and mammals all interact with their surroundings in different ways. As a result, each animal’s exposure to and vulnerability to the effects of pollution on the environment is distinct.

There are two significant effects of air pollution on animals.

It has an impact on the area or habitat in which they live, as well as the availability and quality of the food supply.

• Control of Air Pollution

Controlling air pollution is not straightforward, but it can be done with a few basic methods, such as:

• Avoid Using Automobiles

Taking public transportation will reduce CO emissions into the atmosphere. Carpools can help reduce the number of automobiles on the road, which cuts pollution. To go around, I prefer to walk or ride my bike to various locations.

• Conservation of energy

At the workplace and at home, use energy-efficient electrical devices. When your lights are not in use, you can turn them off. Electrical equipment should be checked on a regular basis to ensure that conservation is not harmed.

• Utilization of Renewable Energy Resources

It will aid in the reduction of pollutants. Instead of burning fossil fuels, we can generate energy from natural resources such as solar energy, wind energy, and so on.

By reducing and eliminating the use of fire and other fire-related materials.

Because industrial emissions are a major source of air pollution, they can be decreased by controlling or treating them at the source. If the reactions of a specific raw material, for example, produce a pollutant, the raw materials can be substituted with less dangerous materials.

Using various fuels is another way to reduce pollution. In many parts of India, CNG – Compressed Natural Gas – vehicles are replacing petrol and diesel vehicles. These are most likely to be used by vehicles that aren’t fully equipped with low-emission engines.

Despite the fact that India has a variety of techniques targeted at improving air quality, most of them have been forgotten or are ineffective. There are still a lot of cars on the road that haven’t been tested for pollutants.

Conclusion

The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gases, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.
