3. •Any visible or invisible particle
or gas found in the air that is not
part of the original, normal
composition to be known as
Pollution.

4. SOURCE OF AIR
POLLUTION
Natural: forest fires, pollen,
dust storm, volcanic eruptions.
Unnatural (man-made): coal,
wood and other fuels used in
cars, homes, and factories for
energy

6. AQI: Air Quality Index
•Indicates whether pollutant levels in air may
cause health concerns.
•Ranges from 0 (least concern) to 500 (greatest
concern)

9. Carbon Monoxide
•colorless, odorless
•produced when carbon does not
burn in fossil fuels
•present in car exhaust
•deprives body of O2 causing
headaches, fatigue, and impaired
vision

10. Sulfur Dioxide
•Produced when coal and
fuel oil are burned
•Present in power plant
exhaust
•Narrows the airway, causing
wheezing and shortness of
breath, especially in those
with asthma

11. Nitrogen Dioxide
•Reddish, brown gas
•Produced when nitric
oxide combines with
oxygen in the atmosphere
•Present in car exhaust and
power plants
•Affects lungs and causes
wheezing; increases chance
of respiratory infection

12. Particulate Matter
•Particles of different sizes and
structures that are released into the
atmosphere.
•Present in many sources including
fossil fuels, dust, smoke, fog, etc.
•Can build up in respiratory system.
•Aggravates heart and lung disease;
increases risk of respiratory infection.

13. Ground Level Ozone
•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
•Irritate respiratory system and asthma;
reduces lung function by inflaming and
damaging lining of lungs

16. •Combination of gases with water
vapor and dust
•It’s a Combination of words smoke
and fog
•Forms when heat and sunlight react
gases (photochemical smog)
•Occurs often with heavy traffic, high
temperatures, and calm winds

18. •1st smog related deaths were in
London in 1873; death toll 500
peoples.
•Limits visibility
•Decreases UV radiation
•Causes respiratory problems and
bronchial related deaths

25. CONTROLS
 The fuels being used should be lead-free as
this will reduce the level of lead in the
atmosphere.
 The polluting gases should be passed
through filters and other device such as
cyclone collector,scrubbers,etc.
 The domestic & industrial smoke
producing units should have long Chimneys
to take the polluting gases far above &then
disperse over a larger area.
