Apart from natural, we also have human-made causes contributing significantly to air pollution due to the dependence on fossil fuels, heavy industries, modern agriculture methods, and waste accumulation. Acid rain thus falling in ground also causes water pollution affecting the water species and land pollution affecting the natural balance of the soil thus degrading the quality of the crops grown. 04. 4. Air pollution is the mixing of any harmful substances to the atmosphere fresh air causing When fossil fuels are burned, they let out oxides into the air. Carbon monoxide which is the principle bearer of air pollution is emitted from the exhaust of the vehicles. 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. [1] Many secondary pollutants are made when a primary pollutant reacts with sunlight. Studies from the University of Birmingham showed that deaths because of pneumonia and air pollution from motor vehicles like cars are related. quality.[1]. [1] Air pollution has been classified as a danger to human health and Earth's many ecosystems for a long time. 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. Most air pollution made by humans today is because of transportation. 4. 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. Air Pollution Essay 150 Words Air pollution has become a big problem these days. In some cases, natural events can as well cause air 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. Household chemicals that is being used without proper ventilation is also a major source of indoor air pollution. But these increased emission of CFCs, bromine, chlorine led to the depletion of ozone layer. 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. Some industries also make chemicals that make poisonous fumes (smoke). What are the causes of air pollution? 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. Human-made air pollution comes from many things. Air pollution occurs when pollutants from various sources enter the air. During the 1980s, scientists found that the ozone layer above the South Pole had thinned by 50 to 98%. The population’s heavy production of waste is the main reason that the air pollution is increasing rapidly. When these oxides mix with water in the atmosphere, they make acid, which fall as precipitation. The end products of certain factories are harmful gases like carbon monoxide, nitrogen oxide. The word air pollution is surrounded by pangs of concern and clouds of worry. Families in developing countries use open stoves for cooking and heating their homes. Pollution meaning, causes of pollution, effects of pollution and conclusion of pollution. Even 2,000 years ago, the Romans were complaining about the polluted air in their cities. 4) While the government ignores the issue of air, Londoners are on toxic fumes. The other objective is to protect us from the harmful radiations of the sun. 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. Many pollutants go into the air from natural sources. Air pollution is known to cause irritation in the eyes, lungs, nose, and throat. Air pollution is majorly caused due to Petroleum produces less pollution per ton, but it causes a lot of pollution since a lot of it is burned globally. The Air Quality Index (AQI) is the system used to calculate a specific region's air pollution. When continually exposed to air pollution, humans become at higher risk for cardiovascular disease. House air pollution can take place due to ignorant factors, for instance, Natural events like volcanic eruption, dust storms and forest fires are natural causes 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 does not often happen, but being exposed to air pollution every day can make people have many health problems. Thus the result is global warming, change in climatic conditions, melting of glaciers, increase in sea level etc. 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. How does pollution affect us? Ozone is a gas that stops harmful ultraviolet rays from the sun. This page was last changed on 16 March 2021, at 16:15. What is the biggest cause of pollution? When toxic pollutants are introduced into the earth’s atmosphere and hampers life, air pollution is said to have occurred. It has also heightened the risk of skin cancer caused by the harmful emission of sunlight. Abundance of these gases causes global warming. In fact, the burning of fossil fuels makes 96% of the sulphur oxides in the atmosphere. It was caused mainly by burning coal, fires. Air pollution can be Man-made and naturally occurring. These pollutants include dust, sea salt, volcanic ashes and gases, smoke from forest fires, pollen, and many other materials. Air is also said to be polluted when there is a presence of poisonous gases in the air we breathe. A global concern is the hole in the ozone layer in the stratosphere. 3) particles can lodge in people's systems and cause serious damage to health. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. However, burning fossil fuels can make a lot of oxides (chemical compounds that have oxygen and other elements inside). Soot And Smog. Pollution can be gas or liquid or solid. However, they are rarely witnessed, and some of them are very disastrous and difficult to prevent from happening. Air Pollution from dust and dirt is also a popular form of air pollution. Indoor air pollution is one of the leading causes of lung cancer. 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. Pollution is the introduction of contaminants into the natural environment that cause adverse change. It all depends where it is in Earth’s atmosphere. Burning of fossil fuel leads to the formation of these poisonous odourless colourless gas called carbon monoxide.
