MEANING (TYPES) OF POLLUTION

INTRODUCTION 

Pollution is the presence in or introduction into the environment of a something which has harmful or poisonous effects.

Pollution can occur naturally, for example through volcanic eruptions, or as the result of human activities, such as the spilling of oil or disposal of household and industrial waste.

This leads to the contamination of the air, water, or soil.

These harmful substances introduced into the environment are called pollutants.

 

TYPES OF POLLUTION

1. Land pollution

2. Water water pollution

3. Air pollution

3. Noise pollution

 

 

MEANING OF WATER POLLUTION

Water pollution is anything that makes our water dirty and unsafe for drinking and general uses.

 

Polluted water is unsafe for humans, animals and plants.

 

HUMAN ACTIVITIES THAT POLLUTED THE WATER

Pollution can happen through human activities like –

Polluted water carried deadly bacteria, such as those responsible for,

1. diarrhea

2. cholera

3. dysentery

4. typhoid

5. death

 

PREVENTION OF WATER POLLUTION

1. Avoid dumping human waste in the water.

 

2. Bury or burn dead farm animals immediately.

3. Don’t wash clothes with detergent or soap in a river or stream.

4. Farm chemicals like Fertilizer, insecticide and pesticides should be apply correctly.

5. Effect on human health

6. Increased risk of wildfires

7. Cause Air pollution

8. Distraction for Tourist

 

PREVENTION OF LAND POLLUTION 

The ways of preventing land pollution include –

 

1. Raising awareness

2. Reduce, Recycle and Reuse

5. Proper waste disposal

4. Afforestation

6. Law and order

 

 

MEANING OF NOISE POLLUTION

Noise pollution means an unwanted and undesirable sound that leads to physical and mental problems.

Noise pollution is dependent on the loudness and frequency of the sound.
