1. Environmental
Pollution
İlayda Guldursun

2. Pollution
 Pollution
is the introduction of
contaminants into a natural environment
that causes instability; disorder, harm or
discomfort to the ecosystem, physical
systems or living organisms.

3. Types of Pollution
 Air
Pollution
 Water Pollution
 Thermal Pollution
 Soil Pollution
 Radioactive Pollution

4. The Importance of Air
 Other
planets have sunlight, but the Earth
is the only planet we know that has air
and water. Without air and water, the
Earth would be unable to sustain life.
Sustain: to continue

5. Air Pollution
 Air
pollution occurs when the air contains gases,
dust, fumes in harmful amounts. That is, amounts
which could be harmful to the health or comfort
of humans and animals or which could cause
damage to plants and materials.

6. Causes of Air Pollution
1-Natural Sources
 Volcanic eruptions
 Forest fires
 Pollen grains of
flower
2-Man-made
Sources
• Increase in
pollution
• Deforestation
• Burning of fossil
fuels and fires
• Wars
• Emission from
vehicles

7. Protecting Clean Water
 Dirty
water is the world's biggest health
risk, and continues to threaten both
quality of life and public health. When
water from rain and melting snow runs off
roofs and roads into our rivers, it picks up
toxic chemicals, dirt, trash.

8. Sources of Water Pollution
 Community
waste waters
 Industrial wastes
 Agricultural sources
 Under ground water pollution
 Thermal pollution

9. Soil Pollution
 Soil
pollution results from the build up of
contaminants, radioactive materials, salts,
chemicals and cancer-causing agents.
 Caused by dumping of wastes
agrochemicals and as indirect result of air
pollution.

10. Sources of Soil Pollution
Salination
Domestic wastes
Agricultural
wastes

11. Control of Soil Pollution
 Proper
disposal od industrial wastes
 Recycling and recovery of materials
 Minimize the manufacture and use od
chemical fertilizers

12. Radioactive Pollution
 It
is the physical pollution of air, water and
land through nuclear materials.
Radioactive materials that cause pollution
may be materials from commercial or
laboratory processes.

13. Sources
1-Man made Sources
 Nuclear weapons
 Reactors and nuclear fuel
 Waste waters containing these wastes
 X-rays used in medical practices

14. Effects
 Mutation
 Cancer
 Increases
infant mortality rate

15. Noise Pollution
 Unwanted
high pitch sound that pollutes
the environment.
 Maximum tolerable intensity of sound is 85
decibels

16. Sources
 The
main sources are automobiles, aero
planes, loudspeakers, industries and other
electro mechanical devices.

17. Effects of Noise Pollution
 Damage
to ear drum and impairment to
hearing.
 Damages heart, liver and brain

18. Thermal Pollution
 The
term thermal pollution has been used
to indicate the detrimental effects of
heated effluents.

19. Causes of Thermal Pollution
 Nuclear
power plants
 Coal fired power plants
 Industrial effluents
 Domestic sewage

20. Control Measures
 Cooling
towers
 Cooling ponds
 Artificial lakes
