3. Pollution is the introduction of contaminants into a natural
environment that causes instability, disorder, harm or
discomfort to the ecosystem i.e. physical systems or living
organisms. Pollution can take the form of chemical
substances or energy, such as noise, heat or light.
Pollutants, the elements of pollution, can be either foreign
substances/energies or naturally occurring contaminants.
Pollution is often classed as point source or nonpoint source
pollution. The Blacksmith Institute issues an annual list of the
world's worst polluted places. In the 2007 issues the ten top
nominees are located
in Azerbaijan, China, India, Peru, Russia, Ukraine and Zambia.

The environmental problems in India are growing rapidly. The
increasing economic development and a rapidly growing population
that has taken the country from 300 million people in 1947 to more
than one billion people today is putting a strain on the
environment, infrastructure, and the country’s natural resources.
Industrial pollution, soil erosion, deforestation, rapid
industrialization, urbanization, and land degradation are all
worsening problems. Overexploitation of the country's resources be it
land or water and the industrialization process has resulted
environmental degradation of resources. Environmental pollution is
one of the most serious problems facing humanity and other life
forms on our planet today.
India's per capita carbon dioxide emissions were roughly 3,000 pounds
(1,360 kilograms) in 2007, according to the study. That's small compared
to China and the U.S., with 10,500 pounds (4,763 kilograms) and 42,500
pounds (19,278 kilograms) respectively that year. The study said that the
European Union and Russia also have more emissions than India
India has been ranked as seventh most environmentally hazardous
country in the world by a new ranking released recently. The study is
based on evaluation of “absolute” environment impact of 179
countries, whose data was available and has been done by researchers in
Harvard, Princeton, Adelaide University and University of Singapore 0n
January 12, 2011.
Brazil was found to be worst on environmental indicators whereas
Singapore was the best. United States was rated second worst and China
was ranked third.

5. Soil contamination occurs when chemicals are released by spill or
underground leakage. Among the most significant soil
contaminants are hydrocarbons, heavy
metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons.

6. Causes of Soil Pollution
We can classify major sources that lead to land following
Categories
O Mining and quarrying
O Sewage waste
O Household Garbage
O Industrial Waste

8. Prevention of Soil
Pollution• More and more land should
be brought under farming
• Trees should be planted
everywhere.
• Avoid drilling the Land for
more underground water.
• Avoid using fertilizers and
Pesticides

Water pollution, by the discharge
of wastewater from commercial and industrial
waste (intentionally or through spills) into surface
waters; discharges of untreated
domestic sewage, and chemical contaminants, such
as chlorine, from treated sewage; release of waste
and contaminants into surface runoff flowing to
surface waters (including urban runoff and
agricultural runoff, which may contain chemical
fertilizers and pesticides); waste disposal and
leaching into groundwater; eutrophication and
littering.

11.  Conserve water by turning off the tap when running water is not
necessary. This helps prevent water shortages and reduces the
amount of contaminated water that needs treatment.
 Be careful about what you throw down your sink or toilet. Don’t
throw paints, oils or other forms of litter down the drain.
 Use environmentally household products, such as washing
powder, household cleaning agents and toiletries.
 Take great care not to overuse pesticides and fertilisers. This will
prevent runoffs of the material into nearby water sources. By having
more plants in your garden you are preventing fertiliser, pesticides
and contaminated water from running off into nearby water
sources.
 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.

12. Air pollution:- the release of chemicals and
particulates into the atmosphere. Common
gaseous pollutants include carbon
monoxide, sulphur
dioxide, chlorofluorocarbons (CFCs)
and nitrogen oxides produced by industry and
motor vehicles.
Photochemical ozone and smog are created as
nitrogen oxides and hydrocarbons react to
sunlight. Particulate matter, or fine dust is
characterized by their micrometre size PM10 to
PM2.5.

15. Mechanical collectors (dust cyclones, multicyclones)
Electrostatic precipitators An electrostatic precipitator (ESP), or
electrostatic air cleaner is a particulate collection device that removes
particles from a flowing gas (such as air) using the force of an induced
electrostatic charge. Electrostatic precipitators are highly efficient
filtration devices that minimally impede the flow of gases through the
device, and can easily remove fine particulate matter such as dust and
smoke from the air stream.
Bag houses Designed to handle heavy dust loads, a dust collector consists
of a blower, dust filter, a filter-cleaning system, and a dust receptacle or
dust removal system (distinguished from air cleaners which utilize
disposable filters to remove the dust).
Particulate scrubbers Wet scrubber is a form of pollution control
technology. The term describes a variety of devices that use pollutants
from a furnace flue gas or from other gas streams. In a wet scrubber, the
polluted gas stream is brought into contact with the scrubbing liquid, by
spraying it with the liquid, by forcing it through a pool of liquid, or by
some other contact method, so as to remove the pollutants

20. Pollution control is a term used in environmental
management. It means the control of
emissions and effluents into air, water or soil. Without
pollution control, the waste products from
consumption, heating, agriculture, mining, manufacturing, t
ransportation and other human activities, whether they
accumulate or disperse, will degrade the environment. In
the hierarchy of controls, pollution prevention and waste
minimization are more desirable than pollution control. In
the field of land development, low impact development is a
similar technique for the prevention of urban runoff
