4
Q
Main Classes of Air Pollutants
A
- Particulate Material
- Nitrogen Oxides
- Sulphur Oxides
- Carbon Oxides
- Hydrocarbons
- Ozone
5
Q
Particulate Material`
A
thousands of different solid or liquid particles suspended in air
- may contain materials with toxic or carcinogenic effects
- extremely small particles can become lodged in lungs
6
Q
Nitrogen Oxides
A
cause difficulty breathing and greenhouse gases
7
Q
Sulphur Oxides
A
cause acid rain
8
Q
Carbon Oxides
A
gases carbon monoxide and carbon dioxide
- greenhouse gases
9
Q
Hydrocarbons
A
some related to photochemical smog and greenhouse gases
10
Q
leap frog effect
A
long distance transportation of air pollutants
- more evaporation at low latitudes (equator) (low volatility)
- more deposition at high latitudes (north/south poles) (high volatitlity)
