What is Air Pollution?
“Air Pollution is the presence in
ambient atmosphere of
substances, generally resulting
from the activity of man in
sufficient concentration, present
for a sufficient time and causes
the harmful effect on
humans, plants and animals.”
Sources of Air Pollution
2. Forest Fires
3. Salt spray from
4. Dust Storms
5. Marshy land
Man Made Sources
4.Fossil fuel burning
7.Domestic burning of
The major primary pollutants include:
Particulate Matter (PM),
Volatile Organic Compounds
Carbon monoxide, and
Atmospheric sulfuric acid is one example of a
Air pollution in urban and industrial areas is often
Photochemical smog, a noxious mixture of gases
and particles, is produced when strong sunlight
triggers photochemical reactions in the
The major component of photochemical smog is
Although considerable progress has been made in
controlling air pollution, the quality of the air we
breathe remains a serious public health problem.
Controlling Air Pollution through
Economic activity, population
growth, meteorological conditions, and
regulatory efforts to control emissions, all
influence the trends in air pollution.
The Clean Air Act of 1970 mandated the setting
of standards for four of the primary pollutants—
carbon monoxide, and
as well as the secondary pollutant ozone.
Have Regulations Helped?
In 1997, the emissions of the five major
primary pollutants in the United States
were about 31 percent lower than 1970.
In 1990, Congress passed the Clean Air
Act Amendments, which further tightened
controls on air quality.
Regulations and standards regarding the
provisions of the Clean Air Act
Amendments of 1990 are periodically
established and revised.
Air is Expensive than
Air is what we Breathe every
Second even during sleep.
Air is sucked into lungs every few seconds
and the alveolar system of the lungs helps
the oxygenation of blood in every drop.
Heart pumps Blood and Blood carries
O2(by Hemoglobin) to every part/cell of the
body to sustain Life inside.
Air Pollution-2 side effects of
Coins1.Pollution & 2. Deforestation
1.Pollution: Pollution is the main cause for
2. Deforestation : Forest/Vegetation on the
side have the capacity to take the carbon
oxides and purify the air around by
releasing oxygen, thus nullifying pollution
to some extent.
But the present day scenario ,pollution is
increasing every second, and same time
on the other site deforestation is
happening aat rapid speed and is
supporting the acceleration of Air
„More O2‟ into the body is called „More
Similarly „Better O2‟ into the body is called
„Polluted O2‟ into the body is called
Effects of Air Pollution on
Eye irritation can be caused by many air
pollutants such as
NOX, O3, PAN, smog, Particulates, etc.
Nose and throat irritation can be caused
by SO2, NOX, pesticides, etc.
Hydrogen fluoride can causes fluorosis
and mottling of teeth.
Irritation of the respiratory tract can be
caused by SOX, NO2, O3, CO, etc.
Dust Particles can causes dust specific
respiratory diseases such as silicosis
Heavy metals like lead can causes
poisoning. Its high concentration can
causes damage liver and kidney.
Pollutants like SO2, O3, H2S and aerosols
damage protective coating and paints of
Damage of textile dyes and textile fibers
is caused by SOX, NOX, and O3.
Soiling increases cost of cleaning shirts
wears, windows, curtains, building
Melting of ice, glaciers.
Affect agricultural output because of
change in pattern in rain fall.
Sewage and garbage heaps emit foul
odours causing further loss of aesthetic
Composition of Air
Atmosphere is the mixture of various
gases and water vapour and
subatomic particles that entirely
covers the earth extending outward
several thousand kilometers. The
major gases in a pollution free dry air
Nitrogen(78%), Oxygen(21%), Argon(
0.9-1.0%) and carbon dioxide.
The minor gases include
Neon, Helium, Methane, Hydrogen, C
arbon Monoxide Ozone etc.
