Soil pollution was brought to public attention in 1978 by the Love Canal disaster. Soil pollution is defined as changes to the physical, chemical, and biological properties of soil caused by human activity that degrade soil quality. Major causes of soil pollution include urbanization, industrial and agricultural wastes, mining, domestic wastes, and radioactive wastes. Disposal of industrial wastes on fertile lands degrades soil quality, while urban wastes slowly poison the soil and damage its fertility. Radioactive elements in polluted soil enter the food chain through plants. Efforts are needed to prohibit disposal of hazardous radioactive wastes in soil and minimize chemical fertilizer and pesticide use.

2. FROM WHOM SOIL POLLUTION CAME INTO NOTICE:
SOIL POLLUTION DUE TO SOIL
WASTE DISPOSAL WAS BROUGHT TO
FOREFRONT OF PUBLIC ATTENTION
BY LOVE CANAL IN1978.

5. SOIL POLLUTION IS
DEFINED AS THE CHANGE
IN PHYSICAL , CHEMICAL
AND BIOLOGICAL
CONDITIONS
OF THE SOIL THROUGH
MAN’S INTERVENTION
RESULTING IN
DEGRADATION IN
QUALITY.

10. FOR AGRICULTURAL

11. DOMESTIC
WASTE:
IT INCLUDES WASTES SUSCH
AS FOOD WASTES, PAPER.,
GLASS,PLASTIC MATERIALS...
CONTRIBUTE TO SOIL
POLLUTION.
RADIOACTIVE
WASTE:
NUCLEAR POWER PLANTS,
NUCLEAR TESTING, AND
EXPLOSION...
ADD VARIABLE AMOUNT OF
RADIOACTIVE MATERIALS TO
SOIL.

12. DISPOSAL OF INDUSTRIES WASTES ON FERTILE
LANDS DEGRADES THE QUALITY OF SOIL.
URBAN WASTE SLOWLY POISON THE
SOIL,DAMAGING
ITS FERTILITY.
RADIOACTIVE ELEMENTS THAT PRESENT IN
POLLUTED SOIL ENTER FOOD CHAIN THROUGH
PLANTS.
WASTES MAY BE RECYCLED...

13. PLANTING OF TREES MUST BE ENCOURAGED...
DISPOSAL OF HAZARDOUS RADIOACTIVE WASTES INTO SOIL SHOULD BE
PROHIBITED...
SOLID WASTE CAN ALSO BE USED FOR ELECTRICITY GENERATION...
USE OF CHEMICAL FERTILIZERS AND PESTICIDES SHOULD BE MINIMISED...
BIODEGRADABLE WASTES USED FOR BIOGAS... AND NON-BIODEGRADABLE

17. •LAND DEGRADATION AND DROUGHT IN
INDIA:
It is important to protect the land from deforestation,
fragmentation, degradation and drought. About 69%
of India's total geographical area is under dry lands
.These areas incidentally are highly populated which
makes the people impacts livelihoods directly .
An estimated 32 percent of India’s total land area is
affected by land degradation.
•
EGYPT:
In the Nile valley and reclaimed desert fringes, land
degradation is caused by water logging, alkalinity of

18. soils
And soil pollution by agrochemicals and chemicals
from industry.
Lands in the eastern desert are degraded due to
water and wind degradation .
Land degradation in western desert are over
exploitation of soil groundwater resources .
Land degradation in northern coastal belts are
degraded due to overgrazing , wind ,conversion of
rangelands in rain fed croplands.
