Definition
• Pollution is the introduction of
contaminants into the natural environment
that cause adverse change, in the form of
killing of life ,toxicity of environment ,
damage to ecosystem and aesthetics of
our surrounding .
(Wikipedia)

Definition (contd)
• An unwanted change in the environment which involves the physical, biological and chemical changes involving air, water and land which affects the human life in one way or the other”.
• Pollution has become a serious issue after World War II in developing countries due to unchecked rapid industrialization. Pollution is the root cause of many diseases that kill and disable living organisms.

the indoor or outdoor environment
by any chemical, physical or
biological agent that modifies the
natural characteristics of the
atmosphere.

How to control air
pollution?
![Page 18: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/18.jpg)
How to control air
pollution?
• Maintaining a healthy distance between the industrial and residential areas.
• The chimneys should be constructed tall in size so that the emissions must be released higher up in the environment
• The sulphur must be removed after burning.
• The gasoline must have anti knocking agents..
• The mining area should be planted with trees.
![Page 19: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/19.jpg)
How to control air pollution?
• The coal fuel should be replaced with gas fuel to control the air pollution.
• The automobiles must be designed with emission control system.
• The wastes must be removed and recycled in the industrial plants and refineries.
• Plants like pine and ribes need to be planted to metabolize the nitrogen oxides and other pollutants.
![Page 20: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/20.jpg)
How to control air
pollution?

in a good condition, and also minimizes fuel
exhaustion
• Using public transportation helps to
prevent the air pollution
• Using alternative energy sources like solar
energy, hydroelectric energy, and wind
energy

Water Pollution….
![Page 23: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/23.jpg)
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.
.
![Page 24: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/24.jpg)
Water Pollution…
• Water pollution affects plants and
organisms living in these bodies of water.
In almost all cases the effect is damaging
not only to individual species and
populations, but also to the natural
biological communities
![Page 25: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/25.jpg)

Preventing Water
Pollution…• Conserve water by turning off the tap.
• Mind what you throw down your sink or toilet.
• Don’t throw paints and oils in water channels.
• Use environment friendly household products, such as washing powder, household cleaning agents etc.
• Take great care not to overuse pesticides and fertilizers.
• Don’t throw litter into rivers, lakes or oceans. Help clean up any litter you see on beaches or in rivers and lakes, make sure it is safe to collect the litter and put it in a nearby dustbin.
![Page 30: Pollution its types, causes and effects by naveed.m](https://reader033.fdocuments.us/reader033/viewer/2022051314/55a596f41a28ab660b8b4624/html5/thumbnails/30.jpg)
Treating Polluted Water...
• Suspended, solid particles and inorganic material can be removed by the use of filters.
• Use of biological filters and processes can naturally degrade the organic waste material.
• After above two steps chemical additives are supplied to get rid of any left-over impurities.
