7. Pollutant is a
* Substance added or present in air causing adverse effect
* It destroys the ecological balance
* It can be solid liquid or gas

8. Pollutants are classified into two
* Primary :directly produced
more powerful
eg:-volcanic eruption , automobile exhaust
* Secondary
indirectly produced
forms when primary pollutants reacts
less powerful
eg:-ground level ozone , smog

9. * Carbon monoxide
* Sulfur dioxide

10. *Colorless , odorless.
*Produced when carbon does not burn in fossil
fuels.
*Present in car exhaust.
*Deprives body of oxygen causing headaches ,
fatigue , and impaired vision.

11. *Produced when coal and fuel oil are burned.
*Present in power plant exhaust
*Narrows the airways , causing wheezing &
shortness of breath.
*Causing asthma.
*Causes acid rain.

12. *Reddish brown gas.
*Produced when nitric oxide combines with
oxygen.
*Present in car exhaust and power plants.
*Affects lungs and causes wheezing; increases
chance of respiratory infection.

13. *Particles of different size and structure that
are released to atmosphere.
*Present in fossil fuels, dust, smoke, fog etc.
*Can build up in respiratory system.
*Aggravates hearts and lung disease.
*Increase risk of respiratory infection.

14. * At upper level, ozone shields earth from sun’s harmful UV
rays.
* At ground level ozone is harmful pollutants.
* Formed from car , power and chemical plant exhaust.
* Reduces lung function & damaging lining of lungs.
* Reduces lung function & damaging lining of lungs.
* Irritate respiratory system
* Creates asthma.

15. On a rainy day
Nature called me for a party
As it was rainy day
Had umbrella of little white beauty.
On the way we saw
Black puff from a foe
She roared at my neighbor
As roads passed
A devil cloud from vehicles
Towards me laughed.

16. I noticed men still working
Goes on working and working
My colleagues started eating
Cigarettes with no worries
My umbrella changes her face
It seem to cry , scream and laugh
Her little shades are fading
She flew here and there
She goes far away from me
Oh! My little pearl vanished
Away from me

17. Oh! My little pearl vanished
Away from me like a black puff
As I comes to my destination
Comes the funeral of nature
And a banner arise with sorrows “SAVE ME PLEASE”

18. * Factories
* Motor vehicles
* Chemicals
* Aerosol sprays
* Landfills

19. * Pollution from power plants , manufacturing industries ,
mines…….
* Smoke released from power plants
* Green house gases or poisonous gases released during
incomplete combustion
* Improper disposal of waste
* Burning of biomass
* Burning of wood , crop waste….

20. * It is considered as the world’s worst industrial disaster.
* Leaked industrial vapors.
* Methyl isocyanate and other chemicals were leaked.
* A gas cloud of hydrogen chloride, carbon monoxide,
nitrogen oxide, monomethyl amine, carbon dioxide etc. was
formed.
* Coughing and vomiting were the immediate effect.
* More than 8000 people died.

22. * Air crafts, marine vehicles , road transport , railways
* Emission of toxic gases like carbon dioxide , sulphur
dioxide , nitrogen , hydrocarbons , volatile substances
*Emission of smoke
*Production of dust during travel

23. * Chemicals , controlled burn , pesticides …
* Odor produced during use of chemical
* Green house gases emitted
* Use of nuclear weapons like atom bomb , hydrogen bomb..
* Smoke , dust particles & other harmful gases

24. * It creates mist of liquid particles
* Includes insecticides , deodorants , paints…
* Produces dangerous particles causing respiratory problems..
* Releases chlorofluro carbons , volatile hydrocarbons , propane ,
nitrogen dioxide , carbon dioxide…

25. * Dumping waste in land is called LANDFILLS
* Produces methane , carbon monoxide , helium…
* It reduces oxygen
* Creates suffocation
* It produces odor.

26. * Radioactive decay in earth crust
* Animals
* Wildfires
* Volcanic eruption

27. * Emission of Radon gas
* Reaction may also causes fire and smoke
* Creates cancer
* Affects lungs

28. * Methane gas is emmited during digestion
* Respiration releases carbon dioxide & absorb oxygen
* Dust is produced during motion

29. * Smoke and carbon monoxide is produced.
* Ash and green house gases are produced.
* Uses large amount of oxygen and emit large amount of
carbon dioxide

30. * Produces sulphur dioxide , chlorine, carbon dioxide, hydrogen
sulphide , hydrogen fluoride and volatile substances
* Produces ash particles and smoke
* Produces water vapour

31. * Air pollution in INDIA is a serious issue.
* Major sources are : firewood & biogas burning , fuel
adulteration , vehicle emission &traffic congestion.
* India has low per capita emission of green house gases
India is world’s largest consumer of firewood , agricultural waste
& biomass.
* Adulterated fuel emission are done by vehicles
* India is world’s largest emitter of carbon dioxide.
* Environmental Performance Index ranked India as having the
poorest relative air quality out of 132 countries.

32. AIR POLLUTION DECREASED.
120
* Air Prevention and Control of Pollution Act was passed in 1981.
100
* Operating compressed natural gas(CNG)mode public transport.
80 * Introduction of metro for large public transport.
60 * Supply of improved quality of diesel, petrol & gasoline.
40 * Stringent emission standard have been implemented.
2008
20 * Mutually time targeted program implemented by CREP(Corporate
2005

responsibility for Environment Protection)
* Controlled pollution from highly polluted industries.
* Heavy duty trucks are allowed only during limited timings.
* Creating awareness to people by using medias.
1995

33. Air Quality Index
Kalamassery
*Vehicular emission is main source.
Aluva
*Industrial exhaust also creates air pollution.
Thripunuthara

breathing, pneunomia, cancer, chronic bronchitis &
emphysema.
* Affect cardiovascular health.
* Indoor air pollution.
* Acid rain.
* Thinning of ozone layer.
* Global warming.
* Ozone layer depletion.

37. * We should need a better environment.
* Conservation is essential for better ecology.
* For proper health and life.
* Air is essential for living so it must be protected.

38. * Reduce use of private vehicles.
* Afforestation.
* Should use more vehicles with less pollution (electric
vehicles).
* Should use cleaner fuel like LPG , CNG ,electricity.
* Should use alternative power sources like wind energy, solar
energy…
* Reducing number of factories and Emission of treated waste
from factories.
* Chimney from factories should be high.
* Reducing use of gadgets which emit CFC’s, like air
conditioners , refridgerator etc.
