This document defines air pollution as particles or gases found in the air that are not part of the original composition. It identifies natural sources such as forest fires and unnatural sources like the burning of fossil fuels. It also defines the Air Quality Index and describes some key air pollutants like carbon monoxide, sulfur dioxide, nitrogen dioxide, and ground-level ozone that are produced by vehicle exhaust and power plant emissions. Finally, it provides some tips individuals can take to help reduce air pollution levels.

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

4. Natural: forest fires,
pollen, dust storm
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, odourless
•produced when carbon
does not burn in fossil fuels
•present in car exhaust

10. Sulfur Dioxide
•produced when coal
and fuel oil are burned
•present in power plant
exhaust.

11. Nitrogen Dioxide
•reddish, brown gas
•produced when nitric
oxide combines with
oxygen in the
atmosphere
•present in car exhaust
and power plants

12. 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

14. •Ride your bike
Tell your friends and family about
pollution
•Switch off lights, fan, heat, etc. when
you leave the room
•Make sure your parents get pollution
checks on their cars
•Ride the school bus
