What is Air Pollution?
Air pollution is an environmental health hazard created by car emissions, chemicals from factories, dust, and other solid particles and gases in the air. People with lung or heart problems may be at greater risk from exposure to air pollutants.
Air is an essential element of our life. Air pollution cannot be clearly defined. Air is a mixture of some gases and moisture. It also contains some inert substances.
We cannot get ‘pure air’ in any part of the world. When we breathe oxygen as well as some other gases and substances enter our respiratory system Before talking about air pollution, it is necessary that we know what are the elements in pure air? The composition of pure air is shown in the following table.

The air element is actually life. Historically, air pollution started with the invention of fire. Thereafter it began to increase with the processing of iron and gold and continues to grow with the use of coal. A new era of pollution began with the invention of the steam engine of the 18th century and with the Industrial Revolution. During this period, along with the increase in motor vehicles, it has increased tremendously. At present, according to the World Health Organization (WHO), ‘Air pollution is a condition under which the elements that harm man and his environment are concentrated in the external environment.’ In other words, air pollution. Air pollution is a quantitative or qualitative change in the normal organization, which affects the life or non-living components of life.
Atmospheric pollution is beyond the political boundaries of the world. It affects distant atmospheres and human settlements from its sources. Power plants (especially coal based), acid rain, motor vehicles, pesticides, forest fires, waste generated by agricultural activities, cigarette smoke, kitchen smoke etc. are major factors in pollution caused by human activities. Before this, discuss these factors in detail, see what is the effect of air pollution on human health and animals and plants.
Major Air Pollutants:
- Sulfur Dioxide (SO2)
- Nitrogen Oxides (NO)
- Carbon Monoxide (CO)
- Solid Particulate Material
- Iron Particles
- Ozone (O3)
- Carbon Dioxide (CO2)
- Some Metals
Sources of air pollution
The process of contamination of air due to natural and human causes is called air pollution. So there are two main sources of air pollution: natural and human. Such as volcanic action, davagni (forest fire), organic waste etc. Lava, rock fragments, water vapour, ash, various gases, etc., emitted during a volcanic eruption contaminate the atmosphere. Due to fire or forest fire, ash, smoke gases etc. pollute the air. Due to decomposition of organic matter in marshy areas, methane gas contaminates the atmosphere. Apart from this, fog, meteorites, microorganisms, pollen grains, marine minerals also play an important role in air pollution. But air pollution from natural sources is relatively limited and less harmful.
Air pollution is increasing continuously by various activities of human beings. The main human sources of air pollution are the following
Destruction of forest
Due to the continuous increase in population, the fulfillment of human demands such as agricultural land, residential land, industrialization etc. has increased. Which is being supplied by cutting down the forests. In the presence of forests, the eco-system remains balanced, due to the destruction of forests, it has become unbalanced. . Industrialization took place all over the world as a result of the Industrial Revolution, but at the same time there has been an increase in serious problems like atmospheric pollution. Various gases emanating from the chimneys of industries like carbon dioxide, sulfur monoxide, sulfur K. Oxides, hydrocarbons, dust particles, vapor particles, smoke etc. are the main factors of air pollution.
Transportation is a very important cause of air pollution. With the increase in population, the means of transport have also increased tremendously. Combustion of petrol and diesel used in automatic vehicles produces many air pollutants such as carbon monoxide, oxides of nitrogen and sulfur, smoke, glass, etc. The combustion of one gallon of petrol by an automatic vehicle pollutes about 5×20 million cubic feet of air. are happening. According to a study, 33 percent of air pollution is due to fumes from vehicles. According to a report by the World Health Organization, the level of air pollution in the major cities of the country is two-three times higher than the prescribed standards. According to an estimate, Delhi has 70 lakh vehicles, Mumbai has more than two lakh auto-rickshaws, more than 9 lakh passenger cars, about 10000 taxis and more than 25 thousand buses, and more than 3 lakh commercial vehicles. Every day 200 new vehicles are added to the 10 lakh vehicles on the road in Lucknow. Jaipur has 15 lakh vehicles, Bangalore has 31 lakh vehicles.
Energy is required for the operation of human life from household works. These include domestic work, industry, agriculture, transportation, etc. Coal, wood, cow dung, kerosene, gases, etc., are used as fuel for domestic purposes like cooking food, heating water, etc. Due to the combustion of these organic fuels, various toxic gases are formed, which pollute the atmosphere. They release pollutants like carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen oxides, organic particles, smoke, etc. LPG gas is more polluting than conventional fuels (wood, coal, upla). The use of refrigerators, air conditioners is a common thing in modern homes. The chlorofluorocarbon gas (CFC) emitted from these electrically powered devices is the most responsible factor for the destruction of the ozone layer present in the atmosphere.
3. Thermal Power Stations
The demand for electricity has also increased in proportion, which is met by coal, natural gases, mineral oils, radioactive materials. Coal, oil, and gas are used as fuel in thermal power plants. Various gases emanating from their chimneys, particles of coal ash are the main factor of atmospheric pollution. A thermal power plant with a capacity of 1000 MW generates from two lakh sixty thousand tonnes to 104000 tonnes of ash in a year. In India, 54 percent of the electricity is generated from coal-based power plants (about 80 thousand MW).
4. Agricultural work
As a result of the Green Revolution in the country, the use of chemical fertilizers has increased in agricultural work. Along with this, various pesticides are being used in the crops. During the spraying of these chemical insecticides, they enter the atmosphere directly or indirectly and spoil the pure atmospheric composition. The permanent effects of many insecticidal chemicals are more dangerous because they take too long to decompose or are not decomposed such as Cdt, BHC, Dieldrin, Endosulfan, etc.
During the mineral activity, Various explosives are used which are the cause of atmospheric pollution. Fine particles produced by mining of various minerals also pollute the atmosphere. Harmful gases emanating from underground mines are also harmful to the atmosphere. The radiation emitted during the mining of nuclear minerals is the cause of various diseases.
Radioactive materials emit alpha, vita, and gamma radiations continuously, which are the people living on the earth. are very harmful to the living beings. Radiation and heat emitted from radioactive materials during nuclear explosions and nuclear weapons testing contaminate the atmosphere. Due to technical and human errors in nuclear power plants, whenever radioactive radiation is released, they cause air pollution.
7. Chemical Substances & Solvents
There are some such substances found or synthesized in nature. Which is physical or chemical also causes air pollution. Pollution is also spread by many solvents used in chemistries and industries. Toxic by-products are obtained during the manufacture of some chemicals-related industries such as rubber, paint, plastic, etc., which pollute the atmosphere as a result of the evaporation process. From developed countries that are endowed with technology and economic terms. Import many items. Cheap machines and other materials from developed countries spread pollution due to being substandard and old. In developed countries, many banned lethal chemicals are given to developing countries at cheap prices or donated, which are the main cause of air pollution. Fireworks etc. also cause air pollution.
8. Effects of air pollution on flora
Humans, as well as vegetation, are equally affected by air pollution. The effect of air pollution is clearly reflected in the vegetation. Acid rain, sun fog, sulfur dioxide, fluorides, ozone, carbon monoxide, etc. obstruct the activities of plants like respiration, growth, flowering, fruit formation, etc. Sulfur dioxide inhibits plant growth. Green deficiency disease occurs due to the loss of foliage in the leaves. Decreased germination of pollen grains hinders the formation of seeds and fruits. Nitrogen oxides cause problems like shortening of leaves etc.
What is smog?
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores can be suspended as particulates. Ozone, a gas, is a major part of air pollution in cities. When ozone creates air pollution, it is also called smog.
Some air pollutants are toxic. Inhaling them can make you more prone to health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution. Air pollution is not just outside – the air inside buildings can also get polluted and affect your health.
What diseases can be caused by air pollution?
Air pollution can cause many diseases, of which the main 5 diseases are as follows
Heart disease Air pollution increases the chances of getting heart disease. Heart attacks, coronary artery disease, blockage in the valves of the heart, etc. can happen.
Lung disease Since, air pollution pollutes the air of the environment.
That is why when people breathe, bad air goes into their body due to which their lungs get damaged.
As in cancer It has been clarified above that due to air pollution, the lungs are also damaged.
So it can also cause lung cancer, due to which many people can also die.
Kidney disease There are many such cases, in which kidney disease is caused by air pollution.
Although kidney disease can be treated with kidney dialysis, it can also cause kidney damage if it is too late. Which can be treated only by kidney transplant.
Threatening to the life of a pregnant woman and her unborn child If a pregnant woman lives in air pollution, then it is not right for her health.
Asthma Air pollution makes the air very polluted, due to which people have to face difficulty in breathing.
Air pollution also causes asthma disease to most of the people.
Reducing the average age of living Recent, many studies have shown that the average live age of people has decreased compared to before.
The main reason for this decrease is air. Increase in pollution
Blood cancer There are many such cases in which people complain of blood cancer due to air pollution.
We all want to be healthy and do everything possible to maintain our health, but when our environment is not healthy then how can we stay healthy.
We have to change this situation so that we can give our next generation a livable environment. Thus, we hope that reading this article has been helpful for you as we have given information about the diseases caused by air pollution and ways to cure it.
What are the 3 types of air pollution?
There are many types of air pollution, of which the main 3 types are Particular Matter, Nidrogen Dioxide, Ozone, Sulfur Dioxide.
Is smog air pollution?
Yes, smog is a type of air pollution, which normally looks like haze, but due to this people have trouble breathing. He was facing problems like cough, burning in eyes etc.
Can a person die from air pollution?
According to the World Health Organization (WHO) statistics, about 7 million people die every year due to air pollution.
Does medical insurance cover cancer treatment?
However, nowadays there are many such insurance companies in the market, which cover many treatments including cancer, but they have their own terms and conditions, which cover only limited treatment of cancer. In other words, medical insurance does not cover the full cost of cancer treatment and some part of it has to be paid by the people out of their own pocket.
What are the main causes of air pollution?
Air pollution is mainly caused by chemical, gas etc. in the air, vehicular fumes, factory smoke, dust from construction works etc.
What is the effect of air pollution?
Air pollution affects humans as well as the environment. If we talk only about man, then air pollution can cause problems like heart disease, lung cancer, kidney failure, kidney failure, etc.
How can air pollution be prevented?
However, air pollution has become a worldwide problem. Despite this, it is a matter of relief that if all of us take some steps like minimizing the use of vehicles, planting trees, not burning leaves, plastics, etc., then air pollution can be prevented to a great extent.
