What is Pollution Means? Main types of pollution
What is Pollution Means? Main types of pollution: Pollution means – the creation of a defect in the natural balance. Neither getting pure air, nor getting pure water, nor getting pure food, nor getting a peaceful environment.
There are many types of pollution! The major pollutants are air pollution, water pollution, and noise pollution.
The stratosphere is about 50 km above the Earth, which contains the ozone layer. This layer absorbs the ultraviolet (UV) rays of sunlight and prevents it from reaching the earth. Today the ozone level is depleting rapidly, due to the chlorofluorocarbon (CFC) gas locate in the atmosphere, the ozone level is decomposing.
Due to the depletion of the ozone levels, the ice deposited on the polar regions has started melting and humans are facing many types of skin diseases. This is a problem arising from the freon and chlorofluorocarbon (CFC) gas used in refrigerators and air conditioners. Air pollutes due to the gases emitted from vehicles and factories. The waste from human creations releases into the rivers, causing water pollution. Land pollution is causes due to the dumping of waste created due to the non-segregation of the residue made by the people.
Main types of pollution
The mixture of chemicals and other fine particles in the atmosphere calls air pollution. Air pollution causes by pollutants such as carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), nitrogen oxides from industry and motor vehicles. Small particles of dust and soil can cause many diseases by reaching the lungs with inhalation.
Effects of Air Pollution:
- Due to polluted air, the number of sunlight decreases, which affects the photosynthesis of plants.
- Air pollution affects the human respiratory system and can cause diseases like asthma, headache, lung cancer, cough, pneumonia, heart disease, vomiting, and cold.
- When it rains in air pollute areas, various types of gases and toxic substances dissolve in the rain and come to the earth, which is called ‘acid rain’.
Major Causes of Air Pollution:
- combustion of fossil fuels in vehicles
- factory smoke
- Use of insecticidal and bactericidal drugs in agriculture
- the solvent used for making polishes and spray paints on the furniture
- rotting of garbage and non-cleaning of drains
Measures to control Air Pollution:
- The height of chimneys of industries should be high
- Use of old vehicle should be ban
- More use of solar energy in homes
- Reduce the use of coal or diesel engines
- Bag filters should be use in factory chimneys
When foreign substances containe in water change the natural properties of water in such a way that it becomes harmful to human health or its usefulness is reduce, then it is calls water pollution.
Effects of Water Pollution:
- In polluted water, algae begin to bloom rapidly and except for a few special types of plants, the rest are destroy.
- Due to the abundance of moss in polluted water, sunlight does not reach depth, which affects the photosynthesis and growth of aquatic plants.
- Animals and birds get various diseases by drinking contaminated water.
- Polio, cholera, dysentery, jaundice, periodic fever, viral fever, etc. diseases that spread in humans due to polluted water.
Major Causes of Water Pollution:
- Unfair activities in the agricultural sector
- Decreased water quality of rivers flowing in the plains
- Social and religious customs, such as shedding the dead body in water, bathing, throwing garbage
- acid rain
Measures to Control Water Pollution:
- Every house should have a septic tank.
- Industrial effluents should not be left in water before treatment.
- The use of dangerous insecticides should be ban.
- Special attention should be paid to the treatment of water from water sources.
- A separate water source should be use for the use of animals.
Noise pollution or excessive noise calls any kind of unusable sound, which causes problems to humans and animals. The main reason for this is the noise generates during the traffic. … There is also a danger of loss of hearing due to excessive noise.
Effects of Noise pollution:
- Microorganisms are also destroy by a loud sound, which hinders the decomposition of dead remains.
- The loud sound also damages the heart, brain, and liver of animals. This damages their nervous system and makes them dangerous.
- Marine whales are most affected by marine noise pollution.
- Noise pollution also affects buildings etc.
Major Causes of Noise pollution:
- The use of household appliances in daily life is the main cause of noise pollution.
- The increasing means of transport in cities (bikes, airplanes, underground trains, etc.) create loud noises.
- Common social events such as weddings, parties, pubs, clubs, discs, or places of worship create noise in residential areas such as temples, mosques, etc.
Measures to control Noise pollution:
- To control the level of unsafe noise in the environment, general awareness should be increase among the people.
- The use of unnecessary noise-generating equipment should be minimized in the house or outside the house such as clubs, parties, bars, discos,s, etc.
