Pollution is the introduction of contaminants into the natural environment that causes harm. There are many types of pollution including air, water, noise, light, radioactive, and thermal pollution. Air pollution involves releasing chemicals and particulates into the atmosphere from sources like industry and vehicles. Water pollution is when waste and contaminants are discharged into surface waters. Noise pollution refers to unpleasant or excessive noise that disrupts human or animal life.

1. • Pollution is the introduction of contaminants into the natural
environment that cause adverse change.
• Pollution is often classed as point source or nonpoint source
pollution.
• Pollutants, the components of pollution, can be either foreign
substances/energies or naturally occurring contaminants.

2. Types of Pollution
• There are many types of pollution
such as air pollution, water
pollution, noise pollution, light
pollution, radioactive pollution
etc..

3. Air Pollution
• Air pollution is the
release of chemicals
and particulates into
the atmosphere.
• Common gaseous
pollutants
include carbon
monoxide, sulfur
dioxide
,chlorofluorocarbons an
d nitrogen
oxidesproduced
by industry and motor
vehicles.

4. Water Pollution
• The release of waste and
contaminants into
surface runoff flowing to
surface waters is called water
pollution.
• Water pollution is caused by
the discharge
of wastewater from commercial
and industrial
waste (intentionally or through
spills) into surface waters.

5. Noise Pollution
• Noise pollution is displeasing
or excessive noise that may
disrupt the activity or balance
of human or animal life.
• The noise pollution worldwide
is mainly caused
by machines and
transportation systems, motor
vehicles, aircrafts, and trains .

6. Radioactive Pollution

7. Thermal
Pollution• Thermal pollution is
a temperature
change in natural
water bodies caused
by human influence.
• This condition
chiefly arises from
the waste heat
generated by an
industrial process
such as certain
power generation
plants.
Thermal Pollution
(water used as a
coolant and thrown
out by factories)

8. Stop Pollution
As there are so many types of
pollution harmful for human beings
we should stop pollution and live in a
healthy eco system.
