Question

Information about pollution and their types

Answer 1

Pollution means the addition of any harmful substances in the environment causes different changes in it.
The word pollution has been derived from the latin word polluta.

Pollution is very much harmful for living beings.Severe damage is caused to living beings due to pollution .People get affected with various diseases like cancer,respiratory diseases, water borne diseases, skin diseases etc. Habitat and food chain of animals are getting destroyed.As a result many animals get extinct . Global warming is causing due to the increase of carbon dioxide and other greenhouse gases. As a result glaciers are melting and resulting into seal level rise.

Pollution is mainly of four kinds .These are air pollution, water pollution, soil pollution and sound pollution.

Soil pollution is very much harmful for us.
By eating the crops produced in polluted soil one may get attacked with various disease including cancer .Fertility of the soil decreases.

Water pollution is a common topic of discussion now .Water pollution causes destruction of habitats of aquatic animals .As a result biodiversity is falling under danger gradually. Harmful chemicals drained out from industries usually causes water pollution.

Air pollution is the addition of harmful gases in the air. Air pollution causes various problems including global warming ,decrease of ozon layer etc.
Noise pollution is a common problem in our everyday life. Noise pollution causes mental and physical problems ,increases depression,problem in ear,headache etc.It is usually caused by use of excessive horns, loud speakers, listening to music in high volume etc. Noise pollution is very much harmful for patients and children.

Therefore,we all should take steps to prevent environmental pollution.Raising public awareness will be the best option. In order to save our environment we all need to be alert about this. Unless the future generation will not get a safe and beautiful environment to grow up.

Answer 2

Pollution comes from the Latin ‘polluere’ which means to contaminate. So, pollution is something that contaminates the environment.

Pollution means the presence of substance in the air, water, and land, which has adverse effects on living organs and on environment. Our environment is in danger due to pollution.

The atmosphere is being polluted by discharge of emissions from industrial plants, domestic sources, running vehicles, which burns fossil fuel and from thermal power etc. Public health and hygiene are seriously effected in the cities of developed and developing countries by presence of Sulphur dioxide, Carbon dioxide, Nitrogen oxide, Carbon monoxide, Hydro carbon substance, etc.

Types
1. Air pollution

Air pollution means the presence of pollutants in the atmosphere is such concentration that causes injury to human being and plants.

Effects: The problems of air pollution.

Damaging to respiratory health.Makes buildings grimy.Aggravates allergies.Causes diseases.
2. Water pollution

Water pollution means contamination of water with physical, chemical or biological properties of water due to discharge of industrial effluent or any other liquid, gases or solid substance into water which is harmful for public health of commercial activities or in agriculture.

Effects: Water pollution has had effects on human life. Water are polluted in different sources such as by gases, dirty soil, minerals, humans’ materials, dead body of animals and other living organisms.

3. Soil pollution

Soil pollution mainly occurs through agricultural chemicals. These are pesticides and fertilizers. These pesticides directly or indirectly injure other animals and human being.

4. Radioactive Pollution

Radioactive pollution refers to the presence of unwanted and undesired radioactive substances that radiates ionizing radiation in the environment and its surroundings. Such radiation is very harmful for the environment.

5. Noise Pollution

One of the greatest problems of modern times is the sound or noise pollution. It refers to the presence of excessive sound or noise in the environment. It is often harmful for human and animal health.

6. Light pollution

Light pollution is caused by excess light contaminating the dark sky and making it artificially light.

Effects of light pollution: Light pollution can disrupt the habitats of animals who rely on natural cycles of light and darkness to tell them when to wake up and when to rest. It can cause stress and disrupted sleep to humans. It can also make stargazing and astronomy difficult due to blocking out starlight.

7. Oil pollution

Oil pollution means oil that has contaminated the land or the sea.

Causes of oil pollution: Oil spills as a result of oil tankers being wrecked or breaking are the main causes of oil pollution.

Effects of oil pollution: Damage to marine habitats and to marine animals (such as fish, gulls and whales).

8. Marine pollution

Marine pollution is presence of substances that contaminates the sea.

Causes of marine pollution: Sewage, oil spills, chemical runoff from industry and plastics and other waste from human lives are major pollutants in the sea. Polluting gases such as CO2 or sulfur dioxide can also dissolve in the sea and pollute it.

Effects of marine pollution: The acidification of the oceans and the destruction of marine habitats (thus in its turn leading to the death of marine organisms and the extinction of several species) are some of the main effects of marine pollution.

9. Plastic pollution

Plastic pollution means plastic products – such as old milk cartons – contaminating the land or the water on planet earth.

Causes of plastic pollution: Humans throwing away plastics carelessly rather than placing them in landfill responsibly or recycling them.

Effects of plastic pollution: Large ‘islands’ of plastic waste have formed in our seas. When ingested by marine animals, as they frequently are, they can cause digestive complications and death.
