• WATER POLLUTION
• LAND POLLUTION

7. AIR POLLUTION:
• Air pollution is the mixture of solid particles and gases in the air,
e.g Smog , fog etc.

8. WATER POLLUTION:
• Any change in the physical ,
chemical or biological properties
of water that will have a
detrimental effects on the living
organisms in water is called water
pollution.

9. LAND POLLUTION
• Land pollution is the
detoriation (destruction) of
the earth’s land surfaces,
often directly or indirectly as
a result of man’s activity and
their misuse of land and
resources.

10. CAUSES AND
EFFECTS OF
POLLUTION

11. Causes of air pollution:

12. Major sources of air pollution are:
Industries
Automobiles and domestic fuel
Sulphur dioxide emitted on burning of fossil
fuel is one of the major causes of air
pollution.

14. When we burn fossil fuel, it release a lot of gases into the air causing air pollution

15. EFFECTS OF AIR POLLUTION:
Air pollution effects :
Human health
Animals
Plants
The atmosphere as a whole
According to WHO report air pollution
in 2012, caused the deaths of around
7 million people worldwide.

16. Effects on Humans

18. NH3
Cl
H2S
Fluoride is very dangerous for plants.

22. CAUSES OF WATER POLLUTION:
• The physical disturbance of land due to
construction of houses, industries, roads, etc.
• Chemicals pollution from industries.
• Inadequate sewage collection and treatment.
• Litter which causes disease and has negative
visual impact.

23. EFFECTS OF WATER POLLUTION:
• About 40 % of deaths
worldwide are caused by
water pollution.
• The main effect caused by
water pollution is the it kills
organisms that depend on
these water bodies.
• Dead fish , crabs , birds , and
dolphins and many other
animals often wind upon
beaches ,killed by pollutants
in their habitat (living
environment).

26. CAUSES OF LAND POLLUTION:
• Land pollution is a major problem around the world and caused by variety of factors.
• Some of the main Causes of land pollution include:
• Deforestation
• Consequent erosion
• Agriculture
• Industry
• Mining
• Illegal dumping of waste
• Urbanization and construction

27. EFFECTS OF LAND POLLUTION:
• As land pollution and soil erosion progress,
animals are forced to shift habitats and adapt to
new conditions, which increases the risk of
extinction.
• The potential effects of soil contamination on
human health include:
• Breathing disorders
• Birth defects
• Skin diseases
• Cancer

28. PREVENTION
FROM
POLLUTION:

29. WHAT IS PREVENTION:
• Preventation is an activity that reduces or eliminates
waste at the source instead of treating the waste after it
is generated.

30. •Avoid
•Reduce
•Reuse or Recycle
•Dispose

31. 1. CONSERVE ENERGY AT HOME ,OFFICES , EVERYWHERE.
2. USE PUBLIC TRANSPORT INSTEAD OF OWN CARS,
BIKES, ETC.
3. USING ENVIRONMENT FRIENDLY PAINTS AND CLEANING
PRODUCT

33. 8 . Adapt the 3Rs of solid waste management:
Reduce, Recycle , Reuse.
9. Inorganic materials such as metals, glass and
plastic ; also inorganic materials like paper,
can be reclaimed or recycled.

34. 10 . Create your green space . Value your garden . Plant
more trees and put indoor plants in your homes as they

following steps:
1. Plant more trees
2. Don’t waste water
3. Use cloth bag and don’t burn platic.

biodiversity, but each individual’s effort to
encourage nature’s wealth must not be
underestimated.”
