What is Air Pollution and its Cause and Effect?

What is Air Pollution?

Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen, and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog. Some air pollutants are poisonous.

Inhaling them can increase the chance you’ll have health problems. People with heart or lung disease, older adults, and children are at greater risk from air pollution. Air pollution isn’t just outside the air inside buildings can also be polluted and affect your health.

There are different types of air pollutants, such as gases (such as ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules.

Air pollution may cause diseases, allergies, and even death to humans; it may also cause harm to other living organisms such as animals and food crops and may damage the natural or built environment. Both human activity and natural processes can generate air pollution.

Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.

The Clean Air Act authorizes the U.S. Environmental Protection Agency (EPA) to protect public health by regulating the emissions of these harmful air pollutants. The NRDC has been a leading authority on this law since it was established in 1970.

What is the Definition of air pollution?

Adding harmful chemicals, biological and/or particles to the atmosphere creates air pollution. Air pollution refers to the release of pollutants into the air that is detrimental to human health and the planet as a whole.

Causes of Air pollution

Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes, and wildfires. The solid and liquid particles suspended in our air are called aerosols.

“Most air pollution comes from energy use and production,” says John Walked, director of the Clean Air Project, part of the Climate and Clean Energy program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.”

And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walked says.

“Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).

Effects of Air pollution

Effects on Humans

People are exposed to a wide variety of health effects when exposed to air pollution. Effects can be divided into short-term and long-term effects.

The temporary short-term effects include diseases such as pneumonia and bronchitis. This also includes symptoms such as irritation of the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea. Bad smells from factories, garbage, or sewer systems are also considered air pollution. These smells are less severe but still unpleasant.

The long-term effects of air pollution can last for years or a lifetime. They can even lead to the death of a person. Long-term health effects of air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs. Some scientists suspect that air pollutants cause birth defects. Every year, nearly 2.5 million people die worldwide as a result of air pollution outdoors or indoors.

People react differently to different types of air pollution. Young children and older adults, who tend to have weaker immune systems, are often more sensitive to pollution. Conditions like asthma, heart disease, and lung disease can be made worse by air pollution. The duration of exposure and the amount and type of pollutants also play a role.

Effects on The Environment

Like humans, animals and plants, entire ecosystems can suffer from air pollution. Like smog, haze is a visible type of air pollution that obscures shapes and colors. Cloudy air pollution can even muffle noise.

Air pollution particles eventually fall back to earth. Air pollution can directly contaminate the surface of water and soil. This can kill plants or reduce their yield. It can kill young trees and other plants.

Sulfur dioxide and nitric oxide particles in the air can create acid rain when they mix with water and oxygen in the atmosphere. These air pollutants come primarily from coal-fired power plants and automobiles. When acid rain falls on the earth, it damages plants by changing the composition of the soil. deteriorates water quality in rivers, lakes, and streams; harms the crop; can cause buildings and monuments to deteriorate.

Like humans, animals can have health effects from air pollution. Birth defects, disease, and lower reproductive rates have all been attributed to air pollution.

Global Warming

Global warming is an environmental phenomenon caused by natural and anthropogenic air pollution. It refers to rising air and ocean temperatures around the world. This rise in temperature is caused, at least in part, by an increase in the number of greenhouse gases in the atmosphere. Greenhouse gases store thermal energy in the earth’s atmosphere. (Usually, more heat from the earth escapes into space.)

Carbon dioxide is one of the greenhouse gases that has had the greatest impact on global warming. Carbon dioxide is released into the atmosphere by burning fossil fuels (coal, gasoline, and natural gas). People rely on fossil fuels to power cars and planes, heat homes, and run factories. This pollutes the air with carbon dioxide.

Other greenhouse gases that are emitted from natural and man-made sources also include methane, nitrous oxide, and fluorinated gases. Methane is a major emission from coal-fired power plants and agricultural processes. Nitrous oxide is a common emission from industrial factories, agriculture, and fossil fuel burning in cars. Fluorinated gases such as fluorocarbons are emitted by industry. Fluorinated gases are often used in place of gases such as chlorofluorocarbons (CFCs). CFCs have been banned in many places because they deplete the ozone layer.

Solutions of air pollution

Maintain restricted use of electronic appliances. A large amount of fossil fuels are burned in order to produce electricity. Air pollution can be reduced by decreasing the number of fossil fuels to be burned. Clean energy technologies such as solar, wind and geothermal are extremely beneficial for the environment.

There are ways to prevent, control and eventually reduce air pollution:

  • Renewable fuel and clean energy production: The most basic solution for air pollution is to move away from fossil fuels, replacing them with alternative energies like solar, wind and geothermal.
  • Energy conservation and efficiency: Producing clean energy is crucial. But equally important is to reduce our consumption of energy by adopting responsible habits and using more efficient devices.
  • Eco-friendly transportation: Shifting to electric vehicles and hydrogen vehicles, and promoting shared mobility (i.e carpooling, and public transports) could reduce air pollution.
  • Green building: From planning to demolition, green building aims to create environmentally responsible and resource-efficient structures to reduce their carbon footprint.
  • Reduce the number of trips you take in your car.
  • Reduce or eliminate fireplace and wood stove use.
  • Avoid burning leaves, trash, and other materials.
  • Avoid using gas-powered lawn and garden equipment.
