Air Pollution Quiz 2

Front 1

london-type smog

Back 1

pollution from coal and smoke in foggy places or temperature inversions. Invention is steam engine.

Front 2

photochemical

Back 2

secondary pollutants forming in sunlight, strong temperature inversion, more automobiles=invention

Front 3

photostationary state reactions for ozone

Back 3

NO + O3 --> NO2 + O2
NO2 + LIGHT --> NO + O
O+ O2 --> O3

Front 4

importance of OH

Back 4

breaks down all organics and most inorganics in the air

Front 5

CO reactions

Back 5

doesn't make much because it breaks down slowly
CO + OH --> CO2 + H
H + O2 --> HO2
NO + HO2 --> NO2 + OH
NO2 + LIGHT --> NO + O
O + O2 --> O3

Front 6

methane reactions

Back 6

CH4 + OH --> CH3 + H2O
CH3 + O2 --> CH3O2
NO + CH3O2 --> NO2 + CH3O
NO2 + LIGHT --> NO + O
O + O2 --> O3

Front 7

ethane reactions

Back 7

C2H6 + OH --> C2H5 + H2O
C2H5 + O2 --> C2H5O2
NO + C2H5O2 ---> NO2 + C2H5O
NO2 + LIGHT --> NO + O
O + O2 --> O3

Front 8

formaldehyde reactions

Back 8

HCHO + LIGHT --> HCO + H
HCHO + LIGHT --> CO + H2
HCHO + OH --> HCO + H2O
HCO + O2 --> CO + HO2
H + O2 --> HO2
(then back to CO equations)

Front 9

most important organics for pollution

Back 9

most important: aromatics, alkenes, aldehydes
Alkanes and CO react slowly but are emitted in greater abundance
fastest to slowest: alkene > aldehyde > aromatic > alcohol > alkane

Front 10

what breaks down ROG's

Back 10

OH, HO2, O, O3, NO3

Front 11

ozone isoplethe chart (ROG limited, NOx limited)

Back 11

when ROG's are high and NOx is low, reduce NOx. When NOx is high and ROG's are low, reduce ROG's. If they're both super high, reduce either.

Front 12

RO: NOx ratios in LA and Atlanta

Back 12

LA: ROG limited (cars produce NOx)
Atlanta: NOx limited
