Marine pollution occurs when harmful substances are discharged into water bodies. Chemicals can accumulate up food chains and cause mutations and disease in marine life and humans. Major sources include point sources like factories and non-point sources like rainfall. Specific types of marine pollution include oil pollution, plastic debris, eutrophication, acidification, and toxins. Several international organizations and laws aim to reduce marine pollution and protect oceans.

3. What is Marine Pollution ?
Marine pollution occurs when harmful
substances like chemicals, plastics, micro-
organisms, radioactive waste, nuclear
waste, industrial waste, domestic waste
and agricultural waste are discharged into
water bodies. like in this picture, red tides
are shown which are caused due to
marine pollution.

6. Point Sources –
Point sources are
sources which are
definite. They do not
change their
position so they can
be controlled
from polluting the
water bodies by
regularly checking
them.
Example- factory.
Non-point Sources-
Non-point sources are
sources which are not
definite. They do
change their position
so they cannot be
controlled from
polluting water
bodies.
Example- rainfall.

8. OIL Poisoning

9. Biomagnification of Inert Materials

10. Acidification
• Acidification means to acidify.
• Marine bodies acidify because they
absorb CO .
• Due to increase in CO concentration, the
oceans absorb more poison and kills its
organisms.

11. Eutrophication
Eutrophication is an increase in
chemical nutrients, typically compounds
containing nitrogen or phosphorus, in
an ecosystem. It can result in an increase in the
ecosystem's primary productivity (excessive
plant growth and decay), and further effects
including lack of oxygen and severe reductions
in water quality, fish, and other animal
populations.

12. Plastic debris
Marine debris is mainly discarded human
rubbish which floats on, or is suspended in
the ocean. Eighty percent of marine debris
is plastic- a component that has been
rapidly accumulating since the end of
World War II. The mass of plastic in the
oceans may be as high as one hundred
million metric tons.
