DEFINITION OF POLLUTION When Harmful Substances Contaminate the Environment it is Called Pollution. Pollution refers to the very bad condition of environment in terms of quantity and quality .

Types of Pollution:

Types of Pollution There are Five types of Pollution Air Pollution Water Pollution Noise Pollution Land Pollution Radio Active Pollution

Effects of Air Pollution:

Effects of Air Pollution Air Pollution affects??? Human health Animals Plants The atmosphere as a whole

How to Avoid Air Pollution:

How to Avoid Air Pollution Yes, we can avoid pollution As Follows Use natural Gases, like lpg autos Do not Burst Crackers Use less Amount of Fuel for Vehicles Avoid using and use electric stoves (bio gas)‏

Water God’s Valuable Gift:

Water God’s Valuable Gift

Definition of Water Pollution:

Definition of Water Pollution The Contamination of water with undesirable substances which make it unfit for usage is termed water Pollution.

Causes of Water Pollution:

Causes of Water Pollution About 40% of Deaths worldwide are caused by Water Pollution. Water Pollution is Caused by organsic and inorganic industrial wastes and affluents discharged into rivers. Noise also causes anxiety stress reacation and fright.

Water Pollution Pictures:

Effects of Water Pollution:

Effects of Water Pollution Diseases like Cholera Malaria Typhoid (spread during the rainy season )‏ Aquatic life gets destroyed

How to Avoid Water Pollution:

How to Avoid Water Pollution Rivers should not be used for washing clothes or bathing animals in. Harvesting of Rainwater to meet water requirements. Dams &embankments must be created. The rivers must not be contaminated. In sacred river like Ganga the dead bodies shouldn’t thrown.


NOISELESS ATMOSPHERE Noise can be simply defined as unwanted sound. The sound is pleasant or not depends upon its loudness,duration,rhythm and the mood of the person. Noise pollution not only results in irritation and anger.

Causes of Noise Pollution :

Causes of Noise Pollution Traffic Noise Air craft Noise Noise from construction and civil engineering works. Noise from the Industries. Noise from other sources.

Effects of Noise Pollution :

Effects of Noise Pollution Hearing Loss High Blood Pressure Stress Sleep Disturbance Color Blindness

How to Avoid Noise Pollution:

Prevention of Land Pollution:

Prevention of Land Pollution More and more land should be brought under farming Trees should be planted everywhere. Waste matter should be disposed immediately Avoid drilling the Land for more underground water. Avoid using more fertilizers and Pesticides.

Definition of Radio Active Pollution:

Definition of Radio Active Pollution Despite the Advantage of nuclear as a clean energy, the big concern is the resulted from nuclear reaction, which is a form of pollution called Radio activity. Radiation (Laser-Rays) will from Radio Active Pollution.

Causes of Radio Active Pollution:

Causes of Radio Active Pollution Nuclear power plants(Ex:Neyveli,Kalpakkam)‏ Nuclear Weapon(Ex:Missiles)‏ Disposal of Nuclear Waste Uranium Mining

Effects of Radio Active Pollution:

Effects of Radio Active Pollution The Diseases include blood in cough Ulcer Swelling of bone joints Cancer Lung Cancer Skin Cancer Bone Cancer Eye Problems

How to Prevent of Radio Active Pollution:

How to Prevent of Radio Active Pollution Avoid Constructing Nuclear Power Plants Avoid Using Nuclear Weapon Have Proper Treatment for Nuclear Waste Avoid mining for Uranium to a minimal
