EFFECTS OF POLLUTION ON HEALTH
• ACKNOWLEDGEMENT

3.  The term Pollution means the introduction of
abnormally high concentrations of harmful
substances to the natural environment.
 It causes discomfort or harm to living organisms and
the ecosystem. It makes the environment unsafe ,
unhealthy and is hazardous to the welfare of the
organisms living in that environment .
 Pollution is often a result of human activities, but it
can occur naturally too.

4.  The substance or agent which contaminates the
environment is called a pollutant.
 It can be a foreign substances or energy, induced into
the environment by humans or it can be a naturally
occurring substance. When the presence of any
natural substance exceeds the normal levels, it is
considered as a contaminant.
 Some common pollutants are
Automobile exhaust fumes ,
Chlorofluorocarbons (CFCs)
Etc.

5. 1) Air Pollution- The atmosphere is a mixture of various
gases and acts as a protective blanket around the earth.
It is the basic life support system of our planet. However,
the air around us is getting polluted day by day, causing
discomfort and harm to humans and other living
organisms.
The depletion of the ozone layer in
the stratosphere has become a
threat to human health and the
Earth’s ecosystem.

7. Water pollution is the contamination of water bodies.
This form of environmental degradation occurs when
pollutants are directly or indirectly discharged into
water bodies without
adequate treatment or
removal of harmful
compounds. Water
pollution affects the
entire biosphere-plants and organisms living in these
water bodies.

9. Land pollution, the deposition of solid or liquid waste
materials on lands or underground in a manner that
can contaminate the soil and groundwater, threaten
Public health, and cause unsightly conditions and
nuisances. When mining sites are abandoned after
excavation work is complete, deep scars are left
behind, causing severe land degradation.

11. Noise pollution or noise disturbance is the disturbing or
excessive noise that may harm the activity or balance
of human or animal life. The source of most outdoor
noise worldwide is mainly caused by machines and
transportation system, motor
vehicles, aircraft , and trains.
Poor urban planning may give rise
to noise pollution, since side-by-
side industrial and residential
buildings can result in noise pollution.

13. Radioactive contamination,
also called radiological
contamination, is the
deposition of, or presence of
Radioactive substances on
surfaces or within solids, liquids or gases, where their
presence is unintended or undesirable.

15. Thermal pollution is the degradation of water quality by
any process that changes ambient water temperature .
A common cause of thermal pollution is the use of water
as a coolant by power plants
and industrial
manufacturers When water
used as a coolant is
returned to the natural
environment at a higher
temperature, the change in temperature decreases
oxygen supply and affects ecosystem composition.

16. THERMAL POLLUTION OF WATER BY POWER PLANTS

17. Light pollution, also known as photo pollution or
luminous pollution, is excessive, misdirected, or
obtrusive artificial light. Light
pollution is the alternation of
light levels in the outdoor
environment due to man-made
sources of light. Indoor light
pollution is such alternation of light levels in the
indoor environment due to sources of light, which
compromises human health.

19. Visual pollution is an aesthetic issue and refers to the
impacts of pollution that impair one’s ability to enjoy a
vista or view. Visual pollution disturbs the visual areas
of people by creating negative
changes in the natural
environment. Billboards, open
storage of trash, space debris,
telephone towers, electric wires,
buildings and automobiles are forms of visual
pollution.

22. WELL I WOULD LIKE TO THANK MY
GEOGRAPHY TEACHER FOR GIVING US A
LOVELY PROJECT TO DO……
I GOT TO KNOW A LOT ABOUT
POLLUTION , ITS EFFECTS AND
MANY MORE… I WOULD ALSO THANK
MY PARENTS FOR HELPING ME……
THANK YOU EVERYONE….

23. THANK
YOU
