1. POLLUTION CONTROL AND
DISASTER MANAGEMENT

2. Environmental Pollution
 Environmental pollution is any
discharge of material or energy
into water, land, or air that
causes or may cause acute (short-
term) or chronic (long-term)
detriment to the Earth's
ecological balance or that lowers
the quality of life.

3. Types of pollution which affect
the environment are:
Air pollution.
Water pollution
Noise pollution
Soil pollution
Marine pollution
Thermal pollution
Radiation pollution.

4. AIR POLLUTION
Contamination of air by smoke and
harmful gases, mainly oxides of
carbon, sulfur, and nitrogen.
Basically these gaseous substances
tend to interfere with human comfort
, welfare and causes environmental
damage. Air pollution causes acid
rain, ozone depletion, photochemical
smog and other such phenomenon.

7. CAUSES
NATURAL CAUSES MAN MADE -CAUSES
 CYCLONES
 VOLCANIC
ERUPTIONS
 EARTH QUAKES
 INDUSTRIAL WASTE
 AUTOMOBILES
 THERMAL POWER
STATION
 NUCLEAR EXPLOSIONS
 NUCLEAR POWER
PLANTS
 AGRICULTURAL
ACTIVITIES
 DISPOSAL OF
GARBAGE.

8. EFFECTS

11. PLANTS
• Affects the movement of the stomata
• Photosynthesis
• Growth of the plant.
• Too much exposure to sulphur dioxide causes
bleaching of the leaf pigment.
• High concentration of carbon monoxide leads
to premature falling of leaves, curling, etc.

12. CLIMATE
GREEN HOUSE EFFECT
GLOBAL WARMING
ACID RAIN
DEPLETION OF OZONE
LAYER.

13. CONTROL
PUBLIC AWARENESS
INDUSTRIAL GASES SHOULD BE
TREATED BEFORE DISCHARGE IN
THE ATMOSPHERE
USE OF ENVIRONMENTAL
FRIENDLY FUELS, SUCH AS GOBAR
GAS, LPG, NATURAL GAS,ETC
RAISING OF GREEN BELTS
SHOULD BE PROMOTED.

15. WATER POLLUTION
• THE CONTAMINATION OF WATER
WITH UNDESIRABLE SUBSTANCES
WHICH MAKE IT UNFIT FOR
USAGE IS TERMED AS WATER
POLLUTION.

16. CAUSES
NATURAL CAUSES MAN MADE CAUSES
 SOIL EROSION
 DEPOSITION OF
DEAD AND
DECAYING REMAINS
OF PLANTS AND
ANIMALS.
 HIGH SPEED WINDS
 FLOODS.
 SEWAGE DISPOSAL
 INDUSTRIAL WASTE
 AGRICULTURAL
WASTE
 HUMAN ACTIVITIES
 CUSTOMS AND
TRADITIONS.
 OIL SPILLS

18. Cleaning
up the Oil
Spill!

20. HUMAN HEALTH
 CAUSES VARIOUS DISEASES TO THE CENTRAL
NERVOUS SYSTEM
 CAUSES DAMAGE TO LIVER , BRAIN AND
KIDNEY.
 IT CAUSES VARIOUS DISEASES LIKE
DIARRHOEA, ABDOMINAL PAINS, SKIN RASH,
JAUNDICE, FEVER, ENLARGED LIVER,ETC.
 TO AN EXTENT IT MAY ALSO CAUSE DEATH.

22. PLANTS
 EXCESSIVE USE OF FERTILIZERS ON CROPS MAY
CAUSE SOME AMOUNT TO BE RETAINED IN THE
SOIL WHICH IS WASHED AWAY DURING RAINS AND
REACHES THE NEAREST WATER BODY.
 EXCESS AMOUNT OF NITRATE PRESENT IN WATER
CAUSES THE GROWTH OF UNWANTED PLANTS.
 CAUSES EUTROPHICATION.
 UNWANTED PLANTS REDUCE THE OXYGEN SUPPLY
TO OTHER AQUATIC PLANTS.
 POLLUTED WATER ALSO CONTAINS HIGH
CONCENTRATION OF METALS WHICH MAY BE
TOXIC FOR PLANTS AND HAMPERS THEIR
GROWTH.

23. ANIMALS AQUATIC ANIMALS ARE DIRECTLY
AFFECTED BY WATER POLLUTION.
 THE HARMFUL CHEMICALS MAKES THE
SURVIVAL OF THE AQUATIC ANIMALS VERY
DIFFICULT.
 DUE TO THIS A LARGE NUMBER OF
AQUATIC SPECIES HAVE BECOME EXTINCT.
 DRINKING POLLUTED WATER COULD BE
VERY POISONIOUS AND MAY CAUSE SEVER
DISEASES AND ALSO DEATH.

24. CONTROL
 INDUSTRIAL WASTE SHOULD BE TREATED IN
ORDER TO REDUCE TOXICITY.
 NON BIODEGRADABLE WASTE MATERIAL
SHOULD NOT BE DUMPED.
 HUMAN ACTIVITIES SUCH BATHING, WASHING
IN RIVERS, THROWING CARCASSES AND
IMMERSING IDOLS SHOULD BE STOPPED.
 PUBLIC AWARNESS.
