today I'm going to discuss is one of the
very burning topic of the Environmental
Studies that is air pollution sources
impact and
mitigation myself Dr in assistant
professor Department of geography and
applied geography University of
nor now let's move on that why this
topic a pollution is so Bing Topic in
today's concern now wherever we are
living whether we are living in the
urban area or in the rural
areas in today's world especially it is
in
2024 we are suffering from various kinds
of health issues and the one of the
prominent health issues that is the eye
irritation as well as our breathing
issue so if we are trying to find out
that what is the result behind this
health issues like the breathing issues
or the ey iritation the main important
reason behind this particular issue that
is air pollution now air pollution is
one of
the topic that we are going to discuss
today because when this urbanization
process is going to take place in any
urban area this air pollution is also
been increasing with the trend of
carbonization because if urbanization is
increasing obviously the air pollution
is also increasing so let's move on to
the first definition of the air
pollution that what is air pollution now
air pollution is the release of the
pollutants such as various kind of gases
particles biological molecules Etc into
the air that is definitely harmful to
human health and the environment as we
know that in the atmosphere
because atmosphere is being started from
the first layer like troposphere
statosphere in that way so all the
particles like the particles like the
SPM suspended particulate matter or
rather than RPM respiratory particulate
matter other typ of gas particles are
also being floating in the atmosphere so
when this this kind of particles or this
kind of dust particle it is in the
atmosphere it is in a limited way so
this is not being harmful for the human
health but due to the anthropogenic
activities like the human activities or
other kind of
activities maybe the external activity
when this kind of dust particles or the
particles which is been already existing
in the atmosphere that is in the
disbalance situation that disbalance
situation is very very much harmful for
the human health as well as the
environment and what is environment
environment is including the Flora and
the F species Flora means the vegetation
and the FAA means the animals animals
human beings all are in the part of the
Flora and funa so this is very important
that the release of the
pollutants as gases and particles and
biological molecules which is not in a
balance situation which is in a
disbalance situation definitely it is
being harmful for the health as well as
the environment now if I am talking
about the generalized definition of the
air pollution now what is the air
pollution air pollution refers to any
kind of physical chemical and biological
changes in the as I told you earlier
when it is in the Balan situation there
is no issues of the air pollution but if
any kind of disbalance if any kind of
changes in terms of the physical in
terms of the chemical in terms of the
biological that is definitely harmful to
the EnV that is definitely harmful for
the human health
too now day by day this air this air
pollution is going to increase why it is
increased because of the main one of the
main reason behind that that is the
anthropogenic activities or the human
activities because we are the human
being we are the sole responsible for
this kind of
air as we know that in today's context
we are very much fond of in the urban
areas so we have more number of vehicles
we have two wheelers we have four
wheelers as well as three wheelers also
running in the arban
more number of Industries are being
there surrounding the urban area so from
the industry from the vehicles this kind
of polutants are being coming up and
that pollutants is it is in the
situation when it is in disbalance
situation to this kind of air pollution
is been coming up and that pollution is
definitely make the negative impact on
the plant animal as well as the human
health and not only that we know one of
the very important term that is called
the global warming now this global
warming is also related with this air
potion because continuously increasing
the carbon dioxide in the atmosphere
which encompasses the increasing of the
temperature in the atmosphere and as we
know that the increasing of carbon
dioxide is also associated with the
increasing of the temperature and that
causes the global warming so right now
it is in the month of almost May and we
are suffering from scatching hits if I'm
talking about the different urban areas
in West Bal like maybe in diling or even
in today's chili what the temperature
that we got almost 20 years back but
right now in shirui this temperature is
to totally high and what is the reason
behind that because of the global so
that is why this air pollution is one of
the issues key issues that we are trying
to discuss
now what next slide we want to discuss
that what are the different type of airs
there are two type of air pollut one is
called as the primary pollutant and
another is called the secondary
pollutant now what is the primary
pollutant the pollutants which are
directly responsible for the air
pollution these are called the primary
pollutants and one of the basic example
of this that is called The sulfur
dioxide and sulfur dioxide emitted from
where sulfur dioxide emed the industries
so these are the solely responsible for
the primary pollut another primary
pollut like carbon monoxides which is
been coming from the vehicle which is
been coming from the which is being
emitted from the vehicle so that is also
the primary
pollutants in terms of the secondary
pollutant what are the secondary
pollutants the pollutants which are
responsible for the air pollution but
not solely directly it is indirectly
responsible for the air pollution or
sometime it is being chemically
Sometimes some gases are being coming
out from the industry of the vehicle and
these gases are being chemically reacted
and that reaction should be responsible
for the air potion so this is called the
secondary air potion best example of the
secondary air pollutants like the smoke
which are being formed by the
intermitting of the smoke and for it is
also responsible for the secondary a
potions now coming to what are the
causes of the air potion there are
causes of air pollution very important
the first reason behind that that is
called the burning
of as we know that fossil fuel what are
the fossil fuel the living which already
been dead so after burning of this
fossil carbon monoxide carbon dioxide
are been coming up and that is totally
responsible for the one of the good
example for this buring of fil like we
have the car we have the vehicle so we
are using petrol and Diesel so this
petrol and Diesel is nothing but that
the burning of the fil so whenever we
are using more number of vehicle more
number of cars on the road flying on the
road so from the engines when this
petrol and Diesel are in in a position
of burning so huge amount of gases are
being coming up and this is one of the
responsible for the
so the combustion of the emits large
amount what is that sulfur dioxide
carbon monoxide which is released from
the incomplete combusion fil foil also
res in pollution the second reason
automobile as I told you earlier what is
automobile the vehicle which are being
flying on the road City Road specially
and obviously the gases which are being
emitted from the vehicle such as if I'm
talking about like Jeep trucks car buses
even the V which are being running on
the road like the two wheelers four
wheelers three wheelers even the buses
where particular this vehicle having the
ages more than 10 or 15 years so
obviously there is a huge chances for
the emission from this automobile then
this is one of the responsible for the
envirment if you are looking in the city
roads sometime you look at the backside
of the particular conversion fight where
this emission are being coming up from
the vehicle it is a black Fuel and that
black fuel is nothing at the combusion
of the which have been coming from the
automobile and one of the responsible
from the greenhouse impact greenhouse
effect in the city so this is the
another second reason for the air
pollution next is the agricultural
activities ammonia is one of the most
hazardous gases emitted during the
agricultural activities even the
insecticides pesticides and the
fertilizer emit from the harmful
chemical that is also contaminate the
air air condition also contaminate the
quality of the air and that is also make
the pollution even sometime you know in
the situation like in Delhi just after
the winter time in particular Punjab
harana and chandad that particular area
is a green B that is the agricultural
land is there and after after the winter
time or during the winter time also the
farmers what they are doing they are
burning the dry leaves and the buckles
of the particular crops so from that
also H smokes are coming toward Delhi
and the surrounding area that is why
during winter time Delhi is a pathetic
situation for the detoriation of the air
quality index what is air quality index
is nothing but that the measurement of
one particular formula which indicates
the quality of the air in the th and
when this air quality index is near more
than 300 or 400 that means the City
Health is going to decline the people
are not being able to suffer the people
are not being able to live in a good way
so this is one of the things so from the
agriculture activities also a pollution
has been going on next factories and the
industries obviously from the factories
and also the industries these are the
main sources of the carbon monoxide as
well as the organic compounds even
hydrocarbon CICS so whenever these are
been coming up from the factories and
industries that is also responsible for
the air pollution in degrading the air
quality next is the mining activities as
we know that in the mining process also
the minerals which are being located
below the AR when it is being extracted
using large pieces of the equipment the
dust and the chemicals released during
the process not only pollute the air but
also dorate the health of the worker who
are being involved in this mining area
and also the people besides near by this
mining so directly or indirectly the
people who are being involved in this
activities mining activities like the
mining labor as well as the people who
are besides the mining area they are
also being impacted by this air
pollution next is the domestic sources
obviously the household cleaning
products and the pains contain of the
toxic chemicals that are also released
in the air so the smell from the newly
tainted world in the smell is the smell
of the present in this point so that's
these are some of the reasons for the
air pollution now what are the effects
of air pollution there are the several
Hazard effects of the air pollution on
the environment is the disease now we
know that air pollution has resulted in
several respiratory disorder and heart
disease among the young as well as the
old age people because if I'm talking
about the cases of the lung cancer which
has been increasing day by day even last
20 years is the the probability of the
lung cancer also been increased so the
main reason behind that air po now the
question is in coming those people are
living in the rural
areas why they are affected by the lung
cancer yes they are being effective but
the percentage of the effectivity of the
lung cancer is less than the urban
because urban areas people they are
directly infected by the Hazardous air
pollution if the people from the rural
area migrating to the urban area then
there is a CH more chances for this kind
of issues like this disorder respiratory
disorder and all these things even the
heart diseases also even the children
living near the polluted areas polluted
areas like where the more pollution are
been coming up the children maybe the
children are running in the park or they
are living in the more polluted areas so
they are also being chances or prone to
pneumonia and as as is a breathing issue
pneumonia is the same thing so
particular at the age of 0 to five years
of age this very crucial because that
time the sensitivity and the capacity of
the children is is basically Below in a
standard so there is high chances for
the pneumonia attack and the as even
many people die every year direct or
indirect effect of
the next impact the global warming as we
told you earlier that global warming is
also one of the impacts by the air
potion if the emission of the greenhouse
gases there is a imbalance situation in
the gous composition of the air and this
has led to an increase in the
temperature of the earth and this
increase art temperature is known as the
global warming as I told you earlier
that in the month of May 20 years back
in that time this temperature is not
being we we we didn't get this kind of
temperature but right now at the month
of May in shiliguri we are experiencing
almost 30 or 35° C this is the reason
for the global warming and just because
of
next is the acid Rin the burning of f
releases harmful Gases such as nitrogen
oxide as well as the sulfur dioxide even
sulfur sulfur dioxide also is suspended
in the air so when the rainfall is being
occur with the rain drop this kind of
gous material Incorporated diluted and
becoming an acidic rainfall on the
particular and if this kind of acidic
rainfall is being occurred so that is
being affected the leaf of the plant
even the human body also even there is a
more chances for the skin infection so
acid Rin is the another impact of the
air now is the ozone layer de now what
is the responsible responsible of ozone
L it basically protects the U Rays
ultraviolet rays which are been coming
from the Sun but due to the release of
the chlorop Carbone alone and the
hydrocarbons in the atmosphere is the
maor causes for the diff of the o lay
and this Deion of the ozone layer is not
only prevent the harmful ultraviolet R
coming from the Sun and causes the skin
diseases and skin cancer also among the
individual even if this ultraviolet R
are been coming it is not being
protected by the ozone that is also
responsible for the ey iritation so just
leave with our present scenario eye
irritation skin cancer asema breathing
issues all are very very much with this
effect of the ation next is effect on
the animals very importantly the air
pollutants which are being suspended in
the water bodies as well as it also
affect the Aquatic Life Aquatic Life
like also this kind of Flora and all the
V that is the vegetations as well as the
fishes in that these are called The
Aquatic light so these are also being
affected by the air pollution so
pollution also comps the animals to
leave their habitat and shift to a new
place because you know sometimes some
form you can find out the greenary it is
nothing but the utopic and why the
utation is coming up because this is a
reason not only the water pollution as
well as the air pollution so the species
can be shifted from one place to another
place they be migrating from one place
to another place due to this kind of air
potion so this render them stay and also
lead to the extinction of the large
number of animal species if you look
about the migratory birs which have been
coming during winter time in our North
Bal University campus right now they are
not being seen because of the air
pollution which are being associated
with shirui and the surrounding area so
these migratory bars are not being
coming to our campus the main reason
obviously the encroachment of the campus
by the buildings and all this things and
the secondary thing is the air so these
are the some of the effects of the air
pollution that we are trying to get from
the air pollution now very important is
how to control the air pollution so
there are several measures to adapt to
incorporate to control the air pollution
first of all avoid the US using the
vles now we are living in the urban area
so we have more number of vles try to
avoid individual or the personal vehicle
instead of using the M vehicle what are
the M Vehicles M vehicle like the you
can use the buses you can use the share
Autos you can use the share taxes so
that can be flying more and more so that
individual vehicle should be avoided and
if we avoid the individual vehicle so
obviously pollution or pollutant which
have been coming from the vehicle that
has been next is the energy conservation
very importantly we have to stop the
Bing of the F instead of using the Bing
of fil we are moving on to the
nonconventional source of energy like
the geothermal energy wind energy this
kind of energy we are trying to apply so
fossil fuel should be using of fossil
Fel should be stopped if I'm talking
about the energy conservation large
number of fil are burn to generate the
electricity if I'm talking about the
thermal electricity so by burning the
coal this kind of thermal electricity
can be generated so we have to and you
know the coal is limited on the AR
because coal is being when particular
coal is being formulated it takes lot of
time
so we have to stop by burning this kind
of coal instead of using some
alternative source of energy then
therefore do not forget to switch off
the electrical appliances when not in
use because most of the time we are
switching on the light on the fan in a
room whenever we are not in VI so we
have to switch off of this light and fan
so we have to control the using of this
electricity so we can also save the
environment in the individual level very
important apart from that also there are
other the use of clean energy resources
solar wind geothermal energy which are
been talking about the alternative
source of energy that can be used at a
larger level and we should as a student
of the PG Department we are also taking
a part for the societal development we
should go to the individual household
and we can award the people that we
should stop using the fum we can use the
other kind of non-conventional source of
energy so that can definitely control
the air pollution even some other method
that also used that by
minimizing and reducing the use of fire
and the fire products number two
obviously industry is one of the sources
of air air pollution so we have to also
be controlled or treated at the source
itself to reduce it effect one example
in that case if the reaction of a
certain raw material yields to autant
obviously we should control this
particular material and instead of using
the material we can sear searching out
some alternative materi even instead of
using the petrol and Diesel we can move
on to the CNG gases we can move on to
the electric vehicles so automatically
pollution level will be reduced not only
that this kind of practices will be
there and most most very importantly
awareness c as a civilized people as a
educated people we should going to rural
areas as well as the urban areas even
the people who are not being AED about
this air pollution we can a them that
what are the result of the air po how we
can mitigate how we can control the air
potion so that can be very important
thing and moreover planting more number
of sapling planting more number of trees
in the field because green is one of the
sources which control the air pollution
because green is a storehouse of the
carbon that the carbon particles so if
we plant more number of trees so
definitely it control the air now coming
to the very important air prevention and
pollution acts which is being operated
by 1981 in central Pollution Control
Board in India now obviously uh that has
been started internationally because the
effects of climate change which are
being responsible for the particular
human health and that is due to this
climate change very associated with the
air potions so particular one of the
conferences has been held in 197 in the
month of June in Stockholm and they have
decided that we have to incorporate one
of the acts which is called the a
prevention and control of pollution act
1981 so that people can understand
people can maintain and people abide
this act so that the air pollution
should be controlled and this act till
now is been going on but it is in a
modified version so very importantly
this act is being operated and and
regarding the pollution of regarding the
control of the air pollution this act is
very important and this act is very
necessary to control the air po so that
is so overall what we have discussing
today the definition of the air
pollution the causes of the air
pollution the impact of the air
pollution and the mitigation strategies
of the air pollution okay thank you
thank you very much
