1. 2.2 - Monitor Air Quality…!
Take a DEEP breath…
Aaaaahhhhhh!!!!!

2. Now take another DEEP breath…
2.2: Monitor Air Quality
Now take another DEEP breath…
R.I.P.
Science 9’s

3. 2.2: Monitor Air Quality Air Composition:
Nitrogen:
78%
Oxygen:
21%
Argon:
<1%
CO2:
0.03%

4. How do we solve this? 2.2: Monitor Air Quality ACID RAIN!!
Sulfur Dioxide [SO2]
Where does it come from?!
- Industrial waste → Oil, Coal, Natural Gas
ACID RAIN!!
How do we solve this?

5. Scrubbers!! 2.2: Monitor Air Quality
Power plants use these to REDUCE SO2
2SO2(g) + 4H2O(l) + 2CaCO3(s)
sulfer dioxide water limestone oxygen
→ 2CaSO4∙2H20(s) CO2(g)
gypsum carbon dioxide
Greenhouse Gas

6. 2.2: Monitor Air Quality Nitrogen Oxide [NO(x)]
Where does it come from?!
- Generating plants and Industrial processes
- Vehicle Combustion
2NO(g) + O2(g) → 2NO2(g)

7. 2.2: Monitor Air Quality Carbon Monoxide [CO(g)]
The “silent killer”…why?
What does it look like?...
It doesn’t.
How does it form?!
- Motor vehicles, combustion of wood/natural gas, industrial processes…
…even smoking
- When there is not enough O2(g) to produce CO2(g)

8. Carbon Monoxide [CO(g)]
2.2: Monitor Air Quality
Carbon Monoxide [CO(g)]
When inhaled, CO(g) reduces the amount of oxygen carried in the blood…
[FYI:] WHY?!
…hemoglobin has a higher affinity to CO(g) than O2(g)

9. O2(g), N2(g), oxides, or VOC’s
2.2: Monitor Air Quality
Ground-Level OZONE [03(g)]
How are they formed?
O2(g), N2(g), oxides, or VOC’s +
Sunlight
OZONE [O3(g)]
VOC’s?! → Volatile Organic Compounds
Found in nature, but mostly man-made

10. 2.2: Monitor Air Quality Ground-Level OZONE [03(g)]
So why is ground-level ozone so bad?
It causes:
-Respiratory problems:
Especially for asthma, colds
- Damage to crops:
Wheat, soybeans, onions
- Deterioration of plastics
Damage here!
…and over there!
OH!…and
some over HERE!!
