The addition of undesirable material into
the environment as a result of human
activities. There are six types.
Air Pollution
The presence of any solid, liquid or gaseous
substance including noise and radioactive
radiation in the atmosphere that may be
injurious to living organisms
Pollutants
Suspended
particulate matter
Smoke from
domestic, industrial
and vehicular soot
Gaseous Pollutants
Part of smoke released
from chimneys of
factories and power
plants
An irritant sound that is unvalued and
unwanted by the recipient
Indoor sources
Noise produced by
radio, TV, electric fans,
air coolers, even
family conflict
Outdoor sources
Indiscriminate use of
loudspeakers,
automobiles, rail traffic,
aeroplanes and public
activities.
Prevention
Better designing
and proper
maintenance of
vehicles
Green belt of
trees absorbs
noise
Sound proofing
equipment like
generators
Water Pollution
Addition of undesirable substances
in water
Sources
Pesticides and
fertilisers used in
agriculture
Oil pollution from
leakage from ships,
oil tankers, etc,
Discharge of
domestic
waste
Prevention
Sewage may
be treated to
make it safe
for disposal
Usage of
eco-friendly
dishwashers
Recycling waste
water for certain
uses wit or with
our treatment
Soil Pollution
Addition of substances which the
quality of soil or its fertility
Sources
Plastic Bags made
from low density
polyethylene
Fly ash, chemical
residues and
nuclear wastes
Fertilizers
and
pesticides
Prevention
Indiscriminate disposal
of solid waste should be
avoided
Stop the use of plastic bags
Sewage should be
treated properly
before being used
Thermal Pollution
Discharge of hot water to water bodies
Sources
Waste heat from boilers
and heating processes
Coal water plants
Waste heat from power plants
Prevention
Allow the water to cool before
releasing it into any water
bodies.
Radiation
Pollution
Increase in over the natural background
radiation
Sources
Nuclear wastes from
nuclear power plants
Radioactive minerals
Cosmic rays
Prevention
Banning of
nuclear tests
Perfect
maintenance of
nuclear reactors
Care should be taken
to check manmade
radiation pollution at
source
Pollutants
Agents that cause environmental pollution.
They can be physical, biological or chemical
substances unintentionally released into the
environment with is harmful to humans and
other living organisms
