The document discusses various types of pollution that affect the marine environment, including sewage, oil, heavy metals, pesticides, polychlorinated biphenyls, radioactive materials, thermal pollution, and solid waste. It describes the sources and impacts of each type of pollution. The key organizations responsible for controlling marine pollution in India are identified. The conclusion emphasizes the importance of keeping the environment clean and following government guidelines to save the earth for future generations.

2. WHAT IS POLLUTION ?
• POLLUTION IS THE
INTRODUCTION OF
CONTAMINANTS INTO
THE NATURAL
ENVIRONMENT THAT
CAUSE ADVERSE
CHANGE.

3. POLLUTION IN ENVIRONMENT
TERRESTRIAL
• AIR
• WATER
• NOISE
MARINE
• SEWAGE
• OIL
• HEAVY METAL
• PESTICIDES
• POLYCHLORINATED BIPHENYLS
• RADIOACTIVE MATERIALS
• THERMAL POLLUTION
• SOLID WASTE

5. 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.,

6. 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
•

7. • 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)

8. 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.

9. 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.

10. 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

11. 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.

12. 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

13. EFFECT OF POLLUTION
SEA LEVEL RISE
GLOBAL WARMING
• SEA LEVEL RISE
• GLOBAL WARMING

14. .
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

15. 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

16. AWARENESS

17. 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.
