Pollution is the introduction of contaminants into the natural
environment that cause adverse change. Pollution can take the
from of chemical substances or energy, such as noise, heat or
light. Pollutants, the components of pollution, can be either
foreign
Substances/energies or naturally occurring contaminants.
Pollution is often classed
As point source or nonpoint source pollution.
Pollution

4. 
Air Pollution
Water Pollution
Soil Pollution
Noise Pollution
Radioactive Pollution
Thermal Pollution
Personal Pollution

5. • Soil pollution is defined or can be described as the
contamination of soil of a particular region.
• Soil pollution is caused by addition of chemicals,
which reduces it’s productive capacity.
• In rural areas more fertilizers & pesticides are used in
agricultural operations & the residual chemicals remain
in the top layers of soil.

6. Soil can be define as
the uppermost crust
of earth mixed with
organic material and
in which animals and
microorganisms live,
and plants grow.

7. Acid rains
Excess application of pesticides,
fertilizer
Urban solid wastes
Disposal of Industrial wastes and
sludge aver land

8. Acid Rain is
caused by air
pollution. The
acidic water
falls on the
soil and
pollutes it by
making the
soil acidic.

9. The use of excess
fertilizers to
increase the crop
yields makes the
soil either acidic or
alkaline and
polluters it.
Ex: ammonium
sulphate , sodium
nitrate.

10. Excess use of Na, Mg,
Ca, K, Zn in the from
of fertilizers &
pesticides inhibit
plan growth &
reduce crop yield.

11.  These wastes include a wet
and fermentable fraction,
made of food residuals
from houses, restaurants
and food industries, paper.

12.  This pollution can
be very massive in
certain areas, where
the industries
discharge their
wastes and really
great is variety of
pollutants: heavy
metals compounds,
asbestos, organic
compounds.

13. 1. Organic waste
2. Compounds
3. Excess use of fertilizers

14. Organic waste
Organic waste enter the soil pores & decompose
pathological bacteria spread infection.
Compounds
Compounds containing arsenic, mercury, chromium,
nickel, lead, Zinc, & iron are toxic to the life.
Fluorides also affect the plant development.
Pollutants

15. 
Excess use of fertilizers
Excess use of Na, Mg, Ca, K, Zn, in the from of
fertilizers & pesticides inhabit plant growth & reduce crop
yield.

18. 

19. Causes cancers including leukemia.
Mercury can increase the risk of kidney
damage.
Also cause headaches, eye irritation & skin
rash.

20. 

21. 
Small life forms may consume harmful
chemicals which may then be passed up
the food chain to large animals.

22. 
Decrease soil fertility.
Reduced crop yield.
Larger loss of soil & nutrients.
Reduced nitrogen fixation.

23. 
 Public health problems.
 Pollution of drinking water sources.
 Foul small & release of gases.
 Waste management problems.

24. 
 Ban on use of plastic bags which are major cause of
pollution in cities
 Recycling of plastic wastes to manufacture many
‘remake’ items.
 Ban on deforestation.
 Encouraging forest replantation programmes.
 Use carefully the fertilizers & pesticides preferable in
optimal does.
