Pollution are of various types but we will be studying the three main types of pollution here.

1. Air Pollution
2. Water Pollution
3. Noise Pollution

Air Pollution: Addition of harmful gases into air is known as Air pollution.

Sources of Air Pollution:

•  Smoke from Industries

•  Burning of fossil fuels(Vehicles etc.)

•  Burning of woods

2.     Water Pollution: Addition of harmful substances into water which contaminates the water is known as water pollution.

 

Sources of Water Pollution: 

• Sewage water 

• Dumping of household waste into water bodies

• Dumping of Industrial waste into water bodies 

3.     Noise Pollution: Prolonged exposure to high intensity of sound (Sound intensity greater than 70 decibel) causes noise pollution.

     Sources of Noise Pollution:

• Traffic Noise

• Air Traffic Noise        

• Construction sites

• Electrical Generators

• Explosions
