WHAT IS POLLUTION ?

• POLLUTION IS THE

INTRODUCTION OF

CONTAMINANTS INTO

THE NATURAL

ENVIRONMENT THAT

CAUSE ADVERSE

CHANGE.

POLLUTION IN ENVIRONMENT

TERRESTRIAL

• AIR

• WATER

• NOISE

MARINE

• SEWAGE

• OIL

• HEAVY METAL

• PESTICIDES

• POLYCHLORINATED BIPHENYLS

• RADIOACTIVE MATERIALS

• THERMAL POLLUTION

• SOLID WASTE

Sewage pollution

• SEWAGE IS DISCHARGED INTO THE

OCEANS ALL OVER THE WORLD

MOSTLY FROM URBAN SETTLEMENT.

• SEWAGE ADDS TO THE AMOUNT OF

SMALL PARTICLES SUSPENDED IN THE

WATER COLUMN AND CONTRIBUTES

LARGE AMOUNTS OF

NUTRIENTS,TOXINS ETC.,

OIL POLLUTION• OIL IS DISCHARGED IN TO THE SEA IN VARIOUS

FORMS AS CRUDE OIL AND AS SEPARATE FRACTIONS. MOST OF THE OIL FRACTIONS ARE

• BIODEGRADABLE. OIL AND ITS FRACTIONS ARE USED IN VARIOUS WAYS

• FROM HOUSEHOLD NEEDS TO AUTOMOBILES AND INDUSTRIES. THE SPILLED

• OIL MORE DEVASTATION IN THE MARINE ENVIRONMENT

• . EMULSIFICATION

•

• THE METALS HAVING THE ATOMIC

WEIGHT MORE THAN TWENTY IS

CONSIDERED AS HEAVYMETALS.

• THE TERM "HEAVYMETALS" IS USED TO

DENOTE ELEMENTS WITH SPECIFIC

WEIGHT HIGHER THAN

• THOSE OF IRON (FE) AND MAINLY LEAD

(PB), MERCURY (HG), COPPER(CU),

CADMIUM (CD) AND CHROMIUM (CR)

PESTICIDES

• PESTICIDES ARE TOXINS (CHEMICAL

COMPOUNDS) USED IN

AGRICULTURAL FARM TO KILL THE

UNWANTED PEST ORGANISMS

ATTACHING THE CULTIVATED

PLANTS. A PESTICIDE IS ANY

SUBSTANCE OR MIXTURE OF

SUBSTANCES INTENDED FOR

PREVENTING, DESTROYING,

REPELLING, OR MITIGATING ANY

PEST.

POLYCHLORINATED BIPHENYLS (PCBS)

• PCBS ARE A SERIES OF TECHNICAL

MIXTURES CONSISTING OF MANY

ISOMERS AND COMPOUNDS THAT

VARY FROM MOBILE OILY LIQUIDS TO

WHITE

• CRYSTALLINE SOLIDS AND HARD NON

CRYSTALLINE RESINS.

RADIOACTIVE MATERIALS

• THE WORLD'S OCEANS HAVE BEEN A

SINK FOR RADIOACTIVE WASTE FROM

THE PRODUCTION OF NUCLEAR

WEAPONS AND ELECTRIC POWER

• IT EFFECT THE DEEP SEA

ACCUMULATED WHEN THE ANIMAL

REPRODUCTION DNA TRANSCRIPT

• IT CAUSE CANCER

THERMAL POLLUTION

• THE NORMAL TEMPERATURE OF

MARINE SOURCE WATER COLUMN IS

INCREASED TO 7-8?C FROM THE

AMBIENT TEMPERATURE.

• IT EFFECT THE COASTAL MANGROVE,

CORAL, SEAWEED AND SEAGRASS IN

NO REPRODUCTION AND NEW

SEEDLING.

SOLID WASTES

• PLASTIC IS PRODUCED IN LARGE

AMOUNT AND HAS DANGER OF SOLID

WASTE INTO THE MARINE

ENVIRONMENT.

• PLASTIC IS NOT BIODEGRADABLE AND

THEREFORE EFFECTING THE OCEANS

FOR LONG PERIODS OF TIME. WHEN

COMPARED TO OTHER TYPES OF

POLLUTANTS THE BIOLOGICAL

CONSEQUENCES ARE LOW

• IT MAKE DEAD

EFFECT OF POLLUTIONSEA LEVEL RISE

GLOBAL WARMING

• SEA LEVEL RISE

• GLOBAL WARMING

.

MARINE POLLUTION CONTROL

• THE MINISTRY OF ENVIRONMENT AND FORESTS UNDER THE ENVIRONMENT

(PROTECTION) ACT, 1986 HAS DECLARED THE COASTAL STRETCHES AS

COASTAL REGULATION ZONE (CRZ) FOR REGULATING THE ACTIVITIES IN THE

CRZ.

• CRZ 1

• CRZ 2

• CRZ 3

• CRZ 4

CENTRAL BOARD OF CONTROL MARINE POLLUTION IN INDIA

• MINISTRY OF ENVIRONMENT AND FORESTS MOES,

• DEPARTMENT OF SCIENCE AND TECHNOLOGY,

• DEPARTMENT OF OCEAN DEVELOPMENT DOD,

• NATIONAL INSTITUTE OF OCEAN TECHNOLOGY NIOT,

• NATIONAL INSTITUTE OF OCEANOGRAPHY NIO,

• INTEGRATED COASTAL AND MARINE AREA MANAGEMENT PROJECT

DIRECTORATE ICMAM

AWARENESS

CONCLUSION

• KEEPING THE ENVIRONMENT CLEAN AND MANAGING THE WASTES WITH THE

GUIDE LINES OF RESPECTIVE OF THE GOVERNMENT

• SAVE THE EARTH FOR OUR FUTURE GENERATION

• DO SOMETHING EVEN IF IT IS VERY SMALL.
