What is Pollution? Types, Causes, Prevention

Human beings are behaving mercilessly and indiscriminately with nature and natural environment to fulfill their selfishness. He is constantly changing nature and the environment through new technology.


Pollution Meaning and Definition

Take unwanted industrial and technical standpoint breathing due to air pollution in areas rich in rarewater - is harmful to drink the water due to pollutionDue to the land being polluted, the land is becoming barren and ruggedhearing due to noise pollution has become rare. Following is some definition of pollution.

What is pollution definition?

The action by which any undesirable changes in the physicalchemical, or biological properties of waterairsoil, and the resources there will cause harmful effects on the biotic world and its entire environment is called pollution. "

 Our way of air to beerwatersoiltrees - plants and animals - animals are required. This change in any component of which her to contaminated or dirtyis called pollution."

What is Pollutant and what do you mean by pollutants?

All those factors, substances, causeselements, or compounds that cause pollution are called Pollutant.

How many types of pollution

 Classification of environmental pollution has several grounds. Among the various grounds of classificationformmedium or meansarea and sourcelocation, etc. are prominent. Environmental pollution is generally divided into two classes. 
1Direct pollution
2Indirect pollution

1. Direct pollution 

 pollution that tree-of plants and animals are directly harmful falls directly on that impact the biosphereis called direct pollutionUnder this, mainly different types of transport modes.

 Fireplaces. Smoke emanating from the burning of airplanesfactorieshouses, and various kinds of goods. The sewage coming out of factories and homespolluted watergarbage collected near cities and villagesmanurefeces and urine of humans and birdstheir dead bodiesindustrial waste materials, etc.

2. Indirect pollution 

 Pollution that does not directly affect the biosphere but indirectly is called indirect pollutionIt includes radioactive substancesall kinds of insecticidesweedicidesfungicidesother types of toxic chemicalsnoise pollution, etc. Anti-social elements like corruption and crime are considered social pollution.

The main types of environmental pollution are -

(1) Air pollution,
(2) Water pollution,
(3) Soil-pollution,
(4) Noise pollution,
(5) Radioactive pollution

(1) Air pollution  

Air is very important for almost all living beings. Oxygen many gases present in the aircarbon dioxide - oxidemust be a balanced percentage of Naitojn and ozone, etc. gases.
air pollution

 For example, if the amount of oxygen and carbon dioxide oxide gas is less or more than the equilibrium ratio, the air is not eligible for respiration. Therefore, the necessary increase of any gas in the air or incorporation of other substances is air pollution.

 On the one hand, it cuts forests, etc. on the other handby running the factoryindustrial institutes, etc. it does not only increase the amount of carbon dioxide in the air but also adds oxides of various elements, etc, in the atmosphere.

(2) Water Pollution  

 Many types of mineralsorganic and inorganic substances in water are dissolved more than a certain proportion of gases or other unnecessary harmful substances cause water pollution.
water pollution

 Water pollutants often cause various disease-causing bacteriaviruses, etc .; Disinfectant substances, Non- sterilizerschemical fertilizersother organic materialsunnecessary substances from industrial institutionssewage, etc. can be many substances. These substances have a profound adverse effect on human health and the economy.

(3) Soil pollution  

The root system of the plants remains in the soil inside the soil. This is why it absorbs most of the raw materials for itself. They require water and air (oxygen) as necessary to maintain the activity of the roots. Soil also gets polluted due to polluted water and air.
soil pollution

These pollutants are mixed with soil with rainwaterFor example, in the air, So2 combines with rainwater to form H2SO4 acid which enters the soil.

Similarly, fertilizers are used to increase or maintain the fertility of the land to produce more crops.
Various types of disinfectants, non- destructive materials, etc. are sprayed on crops which together with the soil can produce harmful effects.

(4) Noise Pollution  

Sound is produced from various types of machinesvehiclesmachines, etc. Loudspeakerssirensinstrumentsmotor-carsbusestrucksaircrafttractors, etc. are the prime examples.
noise pollution

 Sound waves affect various metabolic functions of organisms. Hearing loss occurs due to noise pollution, nervous system diseases can occur and sleeplessness occurs. Noise increases blood pressure and can cause heart disease.

(5) Radioactive Pollution  

Generate particles and rays of different types of the radioactive material environment. The radioactivity of the atmosphere is increased by nuclear power generation centers and molecular tests, etc. Pollution of waterair, and soil by these particles can cause a variety of terrible diseases in trees - plants and other organisms.
Radioactive Pollution

A nuclear explosion with electron-proton particles with a, b, y rays also originate. By this, mutations occur in the genes of chromosomes present inside the cells. Such changes are genetic. 

At the time of the nuclear explosion, excessive heat is generated, which burns wood and melts metals many kilometers away. Radioactive materials produced by detonation enter different layers of the atmosphere.

Later, these substances cool and condense to form droplets, which solidify like small dust particles and spread throughout the world with air. After some time, this radioactive dust starts to sit on the earth and enters the plant by sticking to the leaves of the plants or otherwise. 

When different parts of such plants are used as water or human food, then these radioactive particles can reach their body and cause various diseases.

The major causes of environmental pollution ( Main Causes Of Environmental Pollution)

Unconditionally - Got distorts the balance of the ecological system by harnessing Praktik resources, which is the underlying cause of environmental pollution.

What is point source pollution

(1) The effluents generated by human beingsexcretaurine, and gas containing wastegarbageetc. are due to environmental pollution.   

(2) Environmental pollution is spread by many types of domesticated animals and agricultural activities.

 (3) Many types of pesticidestoxic chemicals, and many types of fertilizers used under intensive agriculture are indirectly one of the main causes of environmental pollution.

(4) Environmental pollution is caused by the immersion of dead bodies of humansanimals in water sources, or combustion in the open or rotting on the earth itself.

(5) Various modes of transport in citiesmetros, air pollution occur due to fuel burning in railbuscarmotorcyclescooteraircraftmotorboat, etc.

(6) Tomorrow - Liquids flowing from factoriesmillsfactories, and other industrial institutionssolid waste materials released in water sources, gaseous substances that are immersed in the atmosphere are due to environmental pollution.

(7) Due to the slums of villagestownsmetrosthere is a lack of space to dispose of waste materialsdirty watergaseous substances in the appropriate placecausing environmental pollution.

8) Pollution is caused by electric power generationatomic power plants. This type of pollution is found more in developed countries and industrial regions.

9) Atomic bombing and testing cause severe pollution of watersoil, and air.

(10) The problem of water pollution also arises due to the availability of oily substances in seawater and other types of water sources.

 Such as Upjat all substances which industriestend to occur by the combustion of fuel or generated as the remains of the substances used in humans and reaching Aust or pollute the environment in the atmospherepollutants ( Pollutants) are called.

In short, it can be said that various types of chemical substances or sometimes physical changes in the abiotic world act as pollutants. There are two types of pollutants in chemical substances.

 How many Kinds Of Pollutants?

There are two types of pollutants depending on the ecosystem.

(1) degrade pollutants ( Degradable Pollutant ) 
Under degrade, pollutant stool - urinegarbage - rubbish emitting various creatures - animals foods and trees - plants come in green or dry organic matter which by natureAs such, they are decomposed into simple compounds by microorganisms and fungi. 

When their quantity is high, their rate of decomposition decreases, and then they pollute the watersoil, and air and cause many diseases in humans and many organisms of its economic importance.

The decomposition of organic matter by microorganisms is necessary to maintain the natural equilibrium, but the rate of degradation slows down when the quantity of degraded substances becomes very high and the pollution of the atmosphere starts with the organic matter.

(2) Non - degradable pollutant 
It contains many types of chemicals that are obtained as waste from industry or as residues of chemicals used in daily life. They are not easily decomposed. In this way chemicals either do not degrade or happen very slowly.

 Such chemicals reach the food chain through waterair, and have harmful effects. Under DDT, plasticaluminum, and other metalsarsenic and mercury compoundscome Final so.

Environmental pollution prevention

The problem of environmental pollution is not a problem of a particular person, but a serious problem of the whole society, so for the prevention of this problem, it is necessary to make every person of the society aware of the environment and ecological knowledge. 

The solution to this problem is impossible with the construction of large equipment and large projects.To solve this problem, we have to take appropriate action keeping in mind the practicality. 

Many such examples are found whose environment can be protected by propagationpropagation, and implementation. No organism can live separately from the environment. 

How can we solve the problem of pollution?

Therefore, it is our duty to protect the environment from pollution, for which the following methods can be adopted.

(1) Use of natural resources at reasonable rates keeping in mind their regeneration.

(2) Make proper use of drinking water and irrigation water resources and keep them safe from getting polluted regularly.

(3) To encourage widespread plantation.

(4) To protect and protect trees from short-sighted cutting.

(5) Use of organic fuels without any requirement or at least.

(6) To collect  waste, sewage, urine, waste material from the settlements in the place, and suppress them by collecting them in large pits for decomposition.

(7) Proper use of pesticideschemicalscosmetics, and medicines.

(8) Substance and non-smoking.

(9) Life - nothing to do dead bodies of animals in water sourcesbut not emit into the open and not burning Btki pits Burial or cremation houses.

(10) Tomorrow - to establish factories away from populated places.

(11) Prohibiting nuclear testing.

(12) Submerging waste materials from nuclear power plants sealed and immersed in the deep seas.

(13) To reduce energy scarcity, make proper use of energy, and use modern energy resources in daily work.
