2. Environmental Pollution
Definition Of Environmental Pollution:
Environmental pollution is the contamination of the physical and
biological components of the earth/atmosphere system to such an extent
that normal environmental processes are adversely
affected.

3. Types Of Environmental Pollution
There are three major types of environmental pollution:
•Air pollution
•Water pollution
•Soil pollution (contamination)

4. AIR POLLUTION
Air pollution is the introduction into
the atmosphere of chemicals, particulate matter,
or biological materials that cause discomfort, disease,
or death to humans, damage other living organisms
such as food crops, or damage the natural environment
or built environment .
Smoke from chimneys, automobile exhaust, burning of
fossil fuels and forest fires result in air pollution

5. Some of the most important air pollutants are sulfur
dioxide, nitrogen dioxide, carbon monoxide, ozone,
volatile organic compounds (VOCs) and airborne
particles, with radioactive pollutants probably among
the most destructive ones (specifically when produced
by nuclear explosions).
Due to increase in the volume of these gases in
atmosphere the ozone layer is depleting because of
which the ultraviolet rays of sun are reaching us and
causing damage to our skin, eyes and other organs.

6. WATER POLLUTION
Water pollution is the contamination of water bodies
(e.g. lakes, rivers, oceans, aquifers and groundwater). Water
pollution occurs when pollutants are discharged directly or
indirectly into water bodies without adequate treatment to
remove harmful compounds.

7. The main sources of water pollution are-
1. Effluent outfalls from factories, refineries, waste
treatment plants etc.. that emit fluids of varying
quality directly into urban water supplies.
Oil Spill
2. Oil spills.
3. In villages people have baths in the river, they wash
their clothes and utensils there because of which
the river water gets polluted.
4. In holy rivers like Ganga people have baths. They
also immerse the dead bodies in the river because
of which the water gets severely polluted.
5. In cities the people throw food wrappers and other
wastes in the water bodies which pollutes the
Deep Water Horizon Oil Spill the reason why Mumbai’s Mithi river is
water. This is
very polluted.

10. SOIL POLLUTION
Soil contamination or soil pollution is caused by the presence
of xenobiotic (human-made) chemicals or other alteration in
the natural soil environment. It is typically caused by industrial
activity, agricultural chemicals, or improper disposal of waste.
The most common chemicals involved are
petroleum hydrocarbons, polynuclear aromatic hydrocarbons
(such as naphthalene and benzo(a)pyrene),solvents,
pesticides, lead, and other heavy metals. Contamination is
correlated with the degree of industrialization and intensity of
chemical usage.

11. Soil contamination can be caused by:
Corrosion of underground storage
tanks (including piping used to transmit the
contents)
Application of pesticides and fertilizers
Mining
Oil and fuel dumping
Disposal of coal ash
Leaching from landfills
Direct discharge of industrial wastes to the soil
Drainage of contaminated surface water into the
soil

14. EFFECTS OF POLLUTION
1. Air Pollution- Air pollution has serious effects on environment as well as human
health. They are:
i. Acid rain is precipitation containing harmful Greenhouse Effectsulfuric
amounts of nitric and
acids. These acids are formed primarily by nitrogen oxides and sulfur oxides
Acid Rain
released into the atmosphere when fossil fuels are burned.
ii. Haze is caused when sunlight encounters tiny pollution particles in the air. Haze
Asthma can be caused
obscures the clarity, color, texture, and form of what we see.
iii. Effects on wildlife. Toxic pollutants in the air, or deposited on soils or surface
waters, can impact wildlife in a number of ways. Like humans, animals can
experience health problems if they are exposed to sufficient concentrations of
air toxics over time. Respiratory problems, reduced lung functioning are certain
problems which can occur in the people.
iv. Ozone depletion- This is a layer present in the atmosphere which protects us
HAZE
from the harmful ultraviolet rays of the sun which can cause skin cancer. But
due to the air pollutants this layer is getting depleted.
Global Warming
v. These gases also cause the Green house effect and Global warming.

vi. The air pollutants also cause diseases in humans like lung cancer, asthma,

16. 3. Soil Pollution- Its effects are:-
Cows die by eating
i. The waste from landfill leaches and causes
plastic bags
contaminates the groundwater.
ii. Certain animals like cows eat waste like plastic bags
and die.
iii. It emits foul odour and becomes breeding ground for
mosquitoes.
iv. The waste on a landfill reduces the fertility of the soil.
v. Pesticides, benzene, chromium and weed killers

established to lead to all kinds of cancer. Long-term
benzene exposure is responsible for irregular

Pesticides like DDT are
carcinogens (cancer causing
substance)
