DEFINITION OF POLLUTION

Pollution is the introduction of contaminants into the natural environment that cause adverse change.
Pollution can take the form of chemical substances or energy, such as noise, heat or light. 
Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

2. TYPES OF POLLUTION 

1. There are four types of Pollution:

• Air Pollution

• Water Pollution

• Noise Pollution

• Land Pollution

1. AIR POLLUTION 

1. What is Atmosphere

1. Atmosphere is the life blanket of Earth.

1. It is therefore essential that we know more about the atmosphere and the ways in which it is Polluted.

1. Air is considered safe when it contains no harmful dust and gases.

1. Causes of Air Pollution

• Industries.
• Automobiles and Domestic fuels.
• High Proportion of undesirable gases, such as sulphur dioxide and carbon monoxide.
• Dust (e.g. cement dust, foundry dust and wind blown solid dust)
• Mist.
• Smoke.

1. Effects of Air Pollution:

• Human health.
• Animals & Plants.
• Global warming.
• Ozone depletion(Ozone hole).
• Acid Rain.
• Various respiratory illnesses.

1. WATER POLLUTION

1. Any physical (temperature, oxygen), chemical(mercury), or biological (disease, sewage) change to water that adversely affects its use by alive beings.

3. Causes of Water Pollution

• About 40% of Deaths worldwide are caused by Water Pollution.

• Water Pollution is Caused by organic and inorganic industrial wastes and effluents discharged into rivers.

• Noise also causes anxiety,stress reaction and fright.

1. Effects of Water Pollution

• Diseases like Cholera.

• Malaria.

• Typhoid (spread during the rainy season).

• Aquatic life gets destroyed.

2. NOISE POLLUTION

1. Noise can be simply defined as unwanted sound.

1. The sound is pleasant or not depends upon its loudness, duration, rhythm and the mood of the person.

1. Noise pollution not only results in irritation an danger.

1. Noise Levels: Decibels (dB) •Intensity •Frequency •Periods of exposure and •Duration

1. Causes of Noise Pollution

• Traffic Noise.
• Aircraft Noise
• Noise from construction and civil engineering works.
• Noise from the Industries.
• Noise from other sources.

1. Effects of Noise Pollution

• Hearing Loss.
• High Blood Pressure.
• Stress.
• Sleep Disturbance.
• Colour Blindness.

2. LAND POLLUTION

1. •One fourth of area is covered by land.
2. •Land is a earth which is occupied by people for shelter,occupation, etc...
3. 
   
4. Causes of Land Pollution

1. We can classify major sources in the following Categories:
2. •Mining, 
3. Erosion and quarrying.
4. •Household Garbage.
5. •Urbanization and Concentration of Population.
6. •Municipal Solid Waste.
7. •Industrial Waste and Hazardous Waste.
8. •Uncontrolled Land Treatment.
9. •Burning open dumps and forest fires.
10. •Deforestation.
11. 
    
12. Effects of Land Pollution

1. •The Land Cannot use to build houses.
2. •Man cannot be farming.
3. •Ground water will gets Affected.
4. •Death of the animals that inhabit the land.
