T U S H A R S H A RMA
*WHAT IS POLLUTION ? 
Pollution is the introduction of contaminants into the 
natural environment that cause adverse change 
to the natural environment. 
In a very simple language pollution any form of alien 
substance 
that’s causing harm to any natural or man made 
environment
*TYPES OF POLLUTION 
A. WATER POLLUTION 
B. SOIL CONTAMINATION 
C. LITTER 
D. AIR POLLLUTION 
E. VISUAL POLLUTION 
F. NOISE POLLUTION 
G. E-WASTE
*
*AIR POLLUTION 
Air pollution is the introduction of harmful 
particles into the Earth atmosphere, causing 
diseases death to human, other organisms such 
as plants or natural or built environment
Contamination by 
Industries
*Sources Of Air Pollution 
• Household combustion devices. 
• Motor vehicles. 
• Industrial facilities. 
• Forest fires
*Pollutants causing Air 
Pollution…… 
*Include particulate matter. 
*Carbon monoxide. 
*Ozone. 
*Nitrogen dioxide . 
*Sulfur dioxide
*Sources & Pollutants
*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.
• 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.
• Timely servicing of the car helps to 
keep it 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 
Water pollution is the contamination of water 
bodies (e.g. lakes, rivers, oceans, aquifers 
and groundwater).
*Polluted Water…
* 
*Domestic sewage. 
*Industrial wastewater. 
*Agricultural wastewater. 
*Construction site stormwater. 
*Urban runoff (stormwater).
* 
*Detergents 
*Chloroform 
*Food processing waste, (fats and grease) 
*Insecticides and herbicides. 
*Petroleum hydrocarbons, (gasoline, diesel fuel, 
jet fuels, and fuel oil). 
*Lubricants (motor oil). 
*From stormwater runoff.
* 
*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.
*
*
Noise pollution is displeasing or 
excessive noise that may disrupt 
the activity or balance of human 
or animal life. 
*
* 
*Machines. 
*Transportation systems. 
*Motor vehicles. 
*Aircrafts. 
*Trains. 
*Poor urban planning.
* 
*Noise pollution affects both health and behavior. 
*Unwanted sound (noise) can damage psychological health. 
*Noise pollution can cause 
*Annoyance 
*Aggression . 
*Hypertension . 
*High stress levels . 
*Hearing loss. 
* sleep disturbances, and other harmful effects.
*
* 
Soil contamination or soil pollution is 
caused by the presence of xenobiotic 
(human-made) chemicals or other 
alteration in the natural soil environment.
* 
•Petroleum hydrocarbons. 
•Lead and Other heavy metals.
* 
• Limit the use of fertilizers and pesticides 
• Awareness about biological control methods and their 
implementation 
• The grazing must be controlled and forest management 
should be done properly 
• The afforestation and reforestation must take place 
• Proper preventive methods like shields should be used in 
areas of wind erosion and wind breaks 
*Treating Wastes of industries. 
*Treating nuclear waste. 
*Proper disposing of plastics and other garbage materials.

* Delhi, (India) 
* Kolkata, (India) 
* Tianjin, (China)

* Kanpur, (India) 
* Lucknow, (India) 
* Jakarta, (Indonesia) 
* Shenyang, (China)

*Go green. 
*Reduce
*THERMAL POLLUTION 
ADDITION OF EXCESS OF UNDESIRABLE 
HEAT TO WATER THAT MAKES IT 
HARMFUL TO MAN, ANIMAL OR AQUATIC 
LIFE
CAUSES 
DISCHARGE OF HEATED WATER OR HOT 
WASTE MATERIAL INTO WATER BODIES 
FROM 
 NUCLEAR POWER PLANTS 
 INDUSTRIAL EFFLUENTS 
 DOMESTIC SEWAGE 
 HYDRO-ELECTRIC POWER 
 COAL FIRED POWER PLANTS
NUCLEAR POWER PLANTS 
 Nuclear power plants use water as a cooling agent. 
 After the water is used, it is put back into a water 
supply at 9-20oC 
 Emissions from nuclear reactor increase the 
temperature of water bodies.
Industrial Effluents 
Discharged water from steam-electric power industry 
using turbo generators will have a higher temperature 
ranging from 6 to 9˚C than the receiving water 
In modern stations, producing 100 MW, nearly one 
million gallons are discharged in an hour with increase 
in temperature of the cooling water passing by 8 to 10 ˚C
Domestic sewage 
Sewage is commonly discharged into lakes, 
canals or streams 
Municipal sewage normally has a higher 
temperature than the receiving water 
Increase in temperature of the receiving 
water decreases the DO of water. 
The foul smelling gases increased in water 
resulting in death of marine organisms
Hydro electric power generation 
Generation of hydroelectric power sometimes results in 
negative thermal loading in water systems 
Creates less heat on water sources less than nuclear 
power plant
CONTROL MEASURES 
 Cooling towers 
 Cooling ponds 
 Spray ponds 
 Artificial lakes
Visual pollution 
Visual pollution is an aesthetic issue and refers 
to the impacts of pollution that impair one's 
ability to enjoy a vista or view. 
Visual pollution disturbs the visual areas of 
people by creating negative changes in the 
natural environment.
* 
*Administrative negligence 
*Excessive advertising 
*Unethical drawing on the walls 
*Public nuisance 
* Vandalism
* 
Effects of exposure to visual pollution include: distraction, eye 
fatigue, decreases in opinion diversity, and loss of identity. 
*Visual Pollution - More Dangerous than You Think It Is
