2. Plan
• Introduction
• Investigate types of pollution
• Consider major problems of
environmental pollution
• Find solutions of global contamination
• Conclusion

3. ENVIRONMENTAL
POLLUTION
 Environmental Pollution can be defined as any undesirable
change in physical, chemical, or biological characteristics of
any component of the environment i.e. air, water, soil which
can cause harmful effects on various forms of life or
property.
 Pollution: The term pollution can be defined as influence of
any substance causing nuisance, harmful effects, and
uneasiness to the organisms
 Pollutant:- Any substance causing Nuisance or harmful
effects or uneasiness to the organisms, then that particular
substance may be called as the pollutant.

4. TYPES OF POLLUTION
WATER POLLUTION
AIR POLLUTION
LAND POLLUTION
NOISE POLLUTION
SOIL POLLUTION

5. Air pollutant impacts
• Greenhouse effect
• Ozone depletion
• acidification
• smog formation
• eutrophication
• human health
• ecosystem health

6. CAUSES OF AIR
POLLUTION
Carbon dioxide-this happens because of
Deforestation and fossil fuel burning.
Sulfur dioxide –Due to the burning of sulfur
containing compounds of fossil fuels.
Sulfur oxides- very dangerous to humans at
a high concentration. Sulfur in the
atmosphere is responsible for acid rain.

physical disabilities
but also psychological and
behavioral disorders in people.

14. Economic effects
EPA places limits on the number of grams/mile of
hydrocarbons, nitrogen dioxide and
carbon monoxide emitted per automobile.
The automobile industry satisfies these standards
by equipping cars with catalytic converters.
In turn, this device raises the cost of cars.
Disadvantages:
- Allow emission of less than the standard free of charge;
- Firms are restricted in the method of compliance;
- Does not take into account differences among firms;
- Does not take into account differences among regions.

15. How to Avoid Air Pollution
• Use natural Gases, like LPG
(Liquefied Petroleum Gas) autos.
• Do not Burst Crackers.
• Use less Amount of Fuel for
Vehicles.
• Avoid using and use electric
stoves (bio gas).

16. • Water pollution affects the entire
biosphere – plants and organisms
living in these bodies of water. In
almost all cases the effect is
damaging not only to
individual speciess and population,
but also to the natural biological
communities.

20. How to Avoid Water
Pollution
• Rivers should not be used for washing
clothes or bathing animals in
• Harvesting of Rainwaterto meet water
requirements.
• Dams & embankments must be created.
• The rivers must not be contaminated.
• In rivers the dead bodies shouldn’t
thrown

21. Conclusion
• Everything on our planet
is interconnected, and while the nature
supplies us with valuable
environmental services without which
we cannot exist, we all depend on each
other’s actions and the way we treat
natural resources.
