Any visible or invisible particle or gas
found in the air that is not part of the
original, normal composition.
Natural:
forest fires, pollen, dust
storm
Unnatural
: man-made; coal, wood
and other fuels used in cars, homes,
and factories for energy
AQI: Air Quality Index
•
Indicates whether pollutant levels in air may cause
health concerns.
•
Ranges from 0 (least concern) to 500 (greatest
concern)

Carbon Monoxide
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
Sulfur Dioxide
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
Nitrogen Dioxide
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
Particulate Matter
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

Occurs often with heavy traffic,
high temperatures, and calm winds

in 1873; death toll 500 people; can you
imagine how much worse the atmosphere
is now?!

Make sure your parents get pollution checks
on their cars
•
Ride the school bus

•
Encourage your parents to carpool to
work
•

you leave the room
CONCLUSION
Air pollution has long been a serious
problem in the world.
Without air, Earth would be unable to
sustain life.

Any visible or invisible particle or gas found in the air that is not part of the original, normal composition.
Natural:forest fires, pollen, dust storm Unnatural: man-made; coal, wood and other fuels used in cars, homes, and factories for energy
AQI: Air Quality Index Indicates whether pollutant levels in air may cause health concerns. Ranges from 0 (least concern) to 500 (greatest concern)
Air Quality Air Quality Index Protect Your Health Good 0-50 No health impacts are expected when air quality is in this range. Moderate 51-100 Unusually sensitive people should consider limiting prolonged outdoor exertion. Unhealthy for Sensitive Groups 101-150 Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. Unhealthy 151-200 Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion, everyone else, especially children should limit prolonged outdoor excertion. Very Unhealthy (Alert) 201-300 Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion everyone else, especially children, should limit outdoor exertion.

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
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
Combination of gases with water vapor and dust 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
1st smog related deaths were in London in 1873; death toll 500 people; can you imagine how much worse the atmosphere is now?! Limits visibility Decreases UV radiation Yellow/black color over cities Causes respiratory problems and bronchial related deaths
Indoor Air Pollution Efficient insulation Bacteria Molds and mildews Viruses animal dander and cat saliva plants house dust Mites Cockroaches pollen
