4. Main pollutants Ozone Particulate Matter Carbon monoxide
Nitrogen Oxides
Sulfur dioxide
Lead

5. Particulate Matter (PM)
Dust, dirt, smoke, liquid droplets.
From cars, buses, factories,
construction sites, chemical
change of gases, burning fuels.
Can be suspended in the air for long
periods of time.

6. Carbon monoxide CO Colorless, odorless gas.
Formed when carbon fuel is not burned
completely.
Contributes to the formation of ground-
level ozone.

7. Nitrogen Oxides NOx Highly reactive gases (nitrogen and oxygen).
Form when fuel is
burned at high
temperatures.
One of the main
ingredients in the
formation of ground-
level ozone and acid rain.

8. Sulfur dioxide SO2 gas Crude oil, metals ( aluminum, copper,
zinc, lead, iron)
Refineries, cement manufacturers,
metal processing facilities.
Contributes to acid rain and acidic
streams.

9. Lead Metal found naturally in the environment.
Motor vehicles, industrial sources.

10. Ozone O3 Gas Created by nitrogen oxides and volatile
organic compounds in the presence of
sunlight.
Bad at ground level

11. Effects Ecosystems Reduction of visibility Global warming Health:
Irritation and inflammation
Breathing difficulties
Lung damage
Heart disease
Vision problems
Premature death

12. What can we do? Use less our cars Carpool Vehicle inspection
Buy water-based products
Do not smoke
Recycle
Plant trees
