Air pollution is a growing problem throughout the world. Air pollution is characterised by the presence of particulate matter in the air of the atmosphere. Ozone is also a greenhouse gas that can be both good and bad for our environment. Many industrial power plants burn fossil fuels to get their energy. [1] Air pollution has been classified as a danger to human health and Earth's many ecosystems for a long time. The filters in air conditioners when not changed regularly combines with air along with its dirt and pollutants leading to the pollution inside house. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.Pollution is often classed as point source or nonpoint source pollution. Pollutants which are the harmful end products of various factories, industries, plants and other establishments are carelessly discharged into the atmosphere leading to pollution of air. Air pollution is the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. Carbon monoxide which is the principle bearer of air pollution is emitted from the exhaust of the vehicles. A global concern is the hole in the ozone layer in the stratosphere. Breathing polluted air puts you at a higher risk of asthma and other respiratory diseases. Certain gases in the atmosphere can cause air pollution. 4. In this Air Pollution Essay, we had described the air pollution causes, its components & how to control air pollution in details.. Air pollution is the mixing of any harmful substances with the atmosphere, which affects the fresh air, human health, quality of life, etc. The natural causes of air pollution are volcanic eruptions and wildfires. But these increased emission of CFCs, bromine, chlorine led to the depletion of ozone layer. What is the biggest cause of pollution? In other words, air pollution is the contamination of air due to the presence or introduction of a substance which has a poisonous effect. Many of the world's large cities today have polluted air or low air and complain about it daily Air pollution contributes to the formation of acid rain, atmospheric precipitation in the form of rain, frost, snow or fog, which are released during combustion of fossil fuels and transformed by contact with water vapor in the atmosphere. Trees are responsible for absorption of many harmful gases like carbon dioxide, carbon monoxide etc and returning oxygen in exchange. In India in 2014, it was reported that air pollution had cut crop yields in the most affected areas by almost half in 2010 when compared to 1980 levels. When fossil fuels are burned, they let out oxides into the air. Indoor air pollution is one of the leading causes of lung cancer. For example, in cities, a gas called ozone is a major cause of air pollution. It initiates acid rain, creates smog, causes cancer, triggers allergies, intensifies symptoms of asthma, leads to respiratory diseases, causes phenomenons like global warming, endangers the flora and fauna and the list thus goes on. It all depends where it is in Earth’s atmosphere. What are the causes of air pollution? 3) particles can lodge in people's systems and cause serious damage to health. This does not often happen, but being exposed to air pollution every day can make people have many health problems. Going into the depth of air pollution the major factors contributing towards the causes of air pollution in points are listed below i. 2) London's famous red buses are the biggest source of dioxide in England's capital city today. Abundance of these gases causes global warming. These pollutants are end product of the various factories, automobiles and many industrial or manufacturing plants. Ozone is a gas that stops harmful ultraviolet rays from the sun. Microparticles, pollen, radioactive elements and gases, lead, smog, and so on are significant air contaminants. Some industries also make chemicals that make poisonous fumes (smoke). Most air pollution made by humans today is because of transportation. In some cases, natural events can as well cause air pollution. The end products of certain factories are harmful gases like carbon monoxide, nitrogen oxide. People start many of those fires. The other objective is to protect us from the harmful radiations of the sun. Dust lifted from tractors in fields and also land clearing and general demolition in the construction field. Every day labour in agricultural and construction industry lifts up dirt and dust that  goes airborne in the atmosphere leading to air pollution. 1) The Great Smog blanketed London with a cloud of toxic pollution for several days in 1952. When continually exposed to air pollution, humans become at higher risk for cardiovascular disease. [1] In fact, there are many more natural pollutants than pollutants that humans make.

The vehicle exhaust fumes in cities form the largest source of air pollution. CFC’s, bromine, chlorine are the main end products of industries and factories. The health of humans, well being of other animals and the natural balance in the ecosystem, everything its and bits of life is threatened by air pollution. Children, elderly (old) people, and people with allergies especially, can have a lot of problems because of air pollution. [1], Secondary pollutants are pollutants that are made from chemical reactions when pollutants mix with other primary pollutants or natural substances like water vapor. This makes us breathe disease causing air inside our houses too. Smoke and harmful gases released by fires, industries, and thermal power plants cause air pollution. Air pollution is the mixing of any harmful substances to the atmosphere fresh air causing [1] Acid precipitation can kill living things like fish and trees, by making the place where they live too acidic. It is also caused by construction works, released from mining and exhaust from industries and factories along with heavy population concentration in cities. [1], Air pollution is usually described as either primary pollutants or secondary pollutants.Primary pollutants are pollutants that are put directly into the air by humans or natural sources. When these oxides mix with water in the atmosphere, they make acid, which fall as precipitation. Man-made Causes: a) There are several factors affecting air pollution, such as we have chemical factories, refineries of petrol, industries of textile, paper and pulp, etc. Even in factories, when production processes are carried out, smoke is produced and it causes pollution. Causes of Air Pollution Following are the important causes of air pollution: Burning of Fossil Fuels The combustion of fossil fuels emits a large amount of sulphur dioxide. It creates respiratory problems and exacerbates existing conditions such as asthma and emphysema. Examples of primary pollutants are exhaust fumes (gas) from cars, soot from smoke, dust storms and ash from volcanic eruptions (as seen in the picture on the left). The most harmful effect of air pollution is global warming, leading to increase in temperatures. When it is near the ground, though, it can poison people and other organisms.[1]. Sometimes the air inside a building is even worse than the air outside. The causes of air pollution can either be anthropogenic (man-made) or natural Before we delve into the causes of air pollution in detail, we must understand the definition of air pollution. How does pollution affect us? What else causes air pollution? The gases inside car exhaust, like nitrogen oxide, make smog and acid rain. The population’s heavy production of waste is the main reason that the air pollution is increasing rapidly. Increased emission of chlorofluorocarbons lead to the depletion of ozone layer which in turn is causing global warming. Air pollution is a type of environmental pollution that affects the air and is usually caused by smoke or other harmful gases, mainly oxides of carbon, sulphur and nitrogen. At that time, the air was thick with smoke from fires and the smell of sewers. Acid precipitation is precipitation, like rain, sleet, or snow, that contains acids from air pollution. The major cause of pollution in the urban areas is automobiles which inefficiently burn petroleum, releases 75% of noise and 80% of air pollutants. When toxic pollutants are introduced into the earth’s atmosphere and hampers life, air pollution is said to have occurred. Causes of Air Pollution. In buildings where the windows are tightly shut to stop air leaks, the air inside can be polluted more than the air outside.[1]. Air pollution is known to cause irritation in the eyes, lungs, nose, and throat. [1] Many things which humans use every day can pollute the air. There are two main causes of air pollution, i.e. Acid rain affects the amount of … These pollutants include dust, sea salt, volcanic ashes and gases, smoke from forest fires, pollen, and many other materials. Many pollutants go into the air from natural sources. Compounds inside carpets, paints, building materials and furniture also pollute the air, especially when they are new. These pollutants include gases, smoke, or minute particles that float in the air. Air Pollution from dust and dirt is also a popular form of air pollution. [2], The World Health Organization said that 2.4 million people died because of the direct problems of air pollution. These factories carelessly excrete these gases in the atmosphere  contributing to air pollution. These two types of air pollution are the most common. The majority of people only perceive air pollution as a consequence of human actions. Sulphur dioxide, nitrogen dioxide and carbon dioxide and other chemicals and pollutants react with water molecules in atmosphere to generate the highly harmful rain called acid rain. Air pollution is not only on the outside. The causes are numerous and so are the solutions. Studies from the University of Birmingham showed that deaths because of pneumonia and air pollution from motor vehicles like cars are related. Anthropogenic air pollution sources are: Families in developing countries use open stoves for cooking and heating their homes. Excess amount of machinery, use of harmful gases, and use of methane are causing the air pollution. The word air pollution is surrounded by pangs of concern and clouds of worry. It is caused by several human activities such as the burning of fossil fuels, firewood, and solid waste. Petroleum produces less pollution per ton, but it causes a lot of pollution since a lot of it is burned globally. From Simple English Wikipedia, the free encyclopedia, "Study links traffic pollution to thousands of deaths", Estimated deaths & DALYs attributable to selected environmental risk factors, by WHO Member State, 2002, "Newly detected air pollutant mimics damaging effects of cigarette smoke", European Commission > Environment > Policies > Air >Air Quality, UNEP Partnership for Clean Fuels and Vehicles, Air Dispersion Modeling Conversions and Formulas, https://simple.wikipedia.org/w/index.php?title=Air_pollution&oldid=7427465, Creative Commons Attribution/Share-Alike License. Vehicular emissions of NOx, CO and SOx gases are another big cause of air pollution. on a large scale. Pollution is the introduction of contaminants into the natural environment that cause adverse change. Thus the result is global warming, change in climatic conditions, melting of glaciers, increase in sea level etc. The traffic of vehicles is one of the causes of air pollution. Pollution can be gas or liquid or solid. Many types of foreign particles, noxious gases and other pollutants discharged from various human actions are changing the fresh air, which harms living beings like human beings, animals and plants. Air pollution is an important environmental issue that concerns the quality of the air we breathe and also compromises our health. Natural events like volcanic eruption, dust storms and forest fires are natural causes of air pollution. It has also heightened the risk of skin cancer caused by the harmful emission of sunlight. Now you can take examples of writing a paragraph on pollution and giving a short speech on pollution. There are certain natural phenomena like a forest fire, volcanic eruption etc which also contribute to … Air pollution also leads to acid rain which may corrode statues, damage crops, forests, lakes. Ozone and smog are secondary pollutants. However, they are rarely witnessed, and some of them are very disastrous and difficult to prevent from happening. Approximately 80% of infectious diseases in the world are caused by contaminated water. Consequences of Air Pollution •CO 2 is a good transmitter of sunlight, but it also partially restricts infrared radiation going back from the earth into space, which produces the so-called greenhouse effect that prevents a drastic Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Even 2,000 years ago, the Romans were complaining about the polluted air in their cities. The Earth's ozone layer protects life from the Sun's harmful ultraviolet rays, but in the 1970s, scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen. Cutting down of these trees leads to lack of absorption of these gases. Farmlands and forests sometimes burn in wildfires producing soot (a black powder composed mainly of carbon, produced when coal, grasses, wood etc. Air pollution is caused by the presence in the atmosphere of toxic substances, mainly produced by human activities, even though sometimes it can result from natural phenomena such as volcanic eruptions, dust storms and wildfires, also depleting the air quality. Pollution meaning, causes of pollution, effects of pollution and conclusion of pollution. Pollution can also be classified by what makes it.
