ENVIRONMENTAL POLLUTION
 Environmental Pollution can be defined as any undesirable
change in physical, chemical, or biological characteristics of any
component of the environment i.e. air, water, soil which can cause
harmful effects on various forms of life or property.
 Pollution: The term pollution can be defined as influence of any
substance causing nuisance, harmful effects, and uneasiness to
the organisms
 Pollutant:- Any substance causing Nuisance or harmful effects or
uneasiness to the organisms, then that particular substance may
be called as the pollutant.

TYPES OF POLLUTION
 WATER POLLUTION
 AIR POLLUTION
 LAND POLLUTION
 NOISE POLLUTION

 Water Pollution can be defined as alteration in
physical, chemical, or biological characteristics of
water through natural or human activities and
making it unsuitable for its designated use.
 Fresh Water present on the earth surface is put to
many uses. It is used for drinking, domestic and
municipal
uses, agricultural, irrigation, industries, navigatio
n, recreation. The used water becomes
contaminated and is called waste water.

INDUSTRIAL WASTE
The major source of water
pollution is the waste water
discharged from industries
and commercial bodies, these
industries are
chemical, metallurgical, food
processing industries, textile,
paper industries. They
discharge several organic and
inorganic pollutants. That
prove highly toxic to living
beings.

INORGANIC POLLUTANTS
 They include fine particles of different metals, chlorides,
sulphates, oxides of iron, cadmium, acids and alkalies.

CAUSES OF AIR POLLUTION
 Carbon dioxide-this happens because of
Deforestation and fossil fuel burning.
 Sulfur dioxide –Due to the burning of sulfur
containing compounds of fossil fuels.
 Sulfur oxides- very dangerous to humans at a
high concentration. Sulfur in the atmosphere
is responsible for acid rain.

CONSEQUENCES OF AIR POLLUTION
 CO2 is a good transmitter of sunlight, but it also
partially restricts infrared radiation going back
from the earth into space, which produces the so-
called greenhouse effect that prevents a drastic
cooling of the Earth during the night.
 CO2 in atmosphere --> GLOBAL WARMING

 Land pollution is the demolition of Earth's land
surfaces often caused by human activities and
their misuse of land resources. It occurs when
waste is not disposed properly.
 Urbanization and industrialization are major
causes of land pollution.

CAUSES OF LAND POLLUTION
 Four Main causes
of land pollution:
 Construction
 Agriculture
 Domestic
waste
 Industrial
Waste

SOURCES OF NOISE POLLUTION
 Transportation systems are the main source of noise
pollution in urban areas.
 Construction of buildings, highways, and streets cause a lot
of noise, due to the usage of air compressors, bulldozers,
loaders, dump trucks, and pavement breakers.
 Industrial noise also adds to the already unfavorable
state of noise pollution.
 Loud speakers, plumbing, boilers, generators, air
conditioners, fans, and vacuum cleaners add to the existing
noise pollution.

EFFECTS OF NOISE POLLUTION
 According to the USEPA, there are direct links between
noise and health. Also, noise pollution adversely affects the
lives of millions of people.
 Noise pollution can damage physiological and
psychological health.
 High blood pressure, stress related illness, sleep disruption,
hearing loss, and productivity loss are the problems related
to noise pollution.
 It can also cause memory loss, severe depression, and panic
attacks.

WAYSTO STOP POLLUTION
 Webelieve that it is the responsible thing to do to
increase recycling.
 It is just like doing laundry and separating blacks
and colors.
 The residents of the country should also try and do
their part and put in at least one day of litter picking
up.
