3. AIR POLLUTION
Definition:
An atmospheric condition in which certain substances present in
concentration effects humans
Air pollution
CAUSES EFFECTS MEASURES

4. CAUSES
NATURALSOURCES MAN MADE IN DOOR POLLUTION
VOLCANIC ERRUPTION
FORESTS FIRES
SEA SALTS APRAYS
BIOLOGICAL DECAY
RADIO ACTIVE MINERALS
MARSHES
EXTRA TERRESTIAL BODIES
THERMAL POWER PLANTS
VECHULAR EMISSION
FOSSIL FUELS
AUTO MOBILES
FERTILISERS
TEXTILE MILES
REFINERIES
MANY HOSES USE FULES LIKE COAL,DUNGS CAKES,WOOD,KEROSENE
CIGARETTE SMOKING
MUSIC SYSTEMS
RADON GAS IS EMMTED FROM BUILDINGS LIKE CONCRETE BRICKS TILES

5. SOIL POLLUTION
 Soil is a thin covering of land soils are arranged in series of zones called
as horizons which are divided into four horizons they are
 O-horizon
 A horizon
 B-horizon
 C-horizon
CAUSES :
 Winds, flowing water
 Human actives such as farming, construction, overgrazing and
deforestation

6. CONSERVATION MEASURES:
 Area treatment
 drainage treatment,
 live check dams,
 Bund construction across the streams
SOIL POLLUTION

7. Thermal pollution
Definition:
Discharge of warm water into river is usually called thermal pollution
CAUSES:
• By Industries
• Power Plants
CONTROL MEASURES:
• COLLING TOWERS
• TO CONSTRUCT LARGE SHALLOW POND
• DISADVANTEGES IN BOTH THE METHODSARE LARGE AMOUNT OF WATER
IS LOST DUE TO EVAPORATION

8. ACID RAINS
ACID RAINS
DEFINITON CAUSES EFFECTS
WHEN FOSSIL FUELS
ARE BURNED CHEMICALS
REACT TO
FORM ACIDS AND REACH
THE GROUND IN FORM OF
ACID RAINS
•ENVIRONMENTAL DAMAGE
•ACID DEPOSITION ON EARTH
•IT DISSOLVES AND &WASHES AWAY NUTRIENTS
•IN SOIL BY DISSOLVING TOXIC SUBSTANCE
•RIVERS BECAME ACIDIC
•EFFECTS PLANTS AND ANIMALS IN ECOSYSTEM
•DESTROYING HISTROCIAL BUILDING-TAJ MAHAL
