#1
Front (Question)

Indoor air pollution is more severe and deadly than…

Back (Answer)

outdoor air pollution

#2
Front (Question)

Indoor air pollution occurs more frequently in….

Back (Answer)

rural areas, as indoor burning is common Modern buildings, however, can still suffer from indoor air pollution

#3
Front (Question)

Primary Pollutant

Back (Answer)

Pollutants being DISCHARGED INTO the troposphere ex: CO2 - carbon dioxide NOx - collective term for nitrogen oxides (NO and NO2) SO2 - sulfur dioxide

#4
Front (Question)

NOx

Back (Answer)

collective term for nitrogen oxides (includes NO and NO2)

#5
Front (Question)

SO2

Back (Answer)

sulfur dioxide

#6
Front (Question)

CO2

Back (Answer)

carbon dioxide

#7
Front (Question)

Secondary Pollutant

Back (Answer)

Pollutant formed from a reaction between primary Pollutant and other chemicals Ex: SO3 H2SO4 O3

#8
Front (Question)

SO3

Back (Answer)

Sulfur Trioxide

#9
Front (Question)

H2SO4

Back (Answer)

Sulphric acid

#10
Front (Question)

O3

Back (Answer)

Ozone

#11
Front (Question)

Thermal Inversion

Back (Answer)

the lack of mixing/convection due to density difference (warm, lower density air already positioned on top)

#12
Front (Question)

Ozone

Back (Answer)

Stratospheric ozone is good. It helps block harmful UV and UVB from the sun. Tropospheric ozone is bad. It’s an irritant

#13
Front (Question)

Five main greenhouse gases

Back (Answer)

carbon dioxide, methane, nitrous oxide, and water vapor

#14
Front (Question)

Carbon Dioxide (CO2) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

colorless and odorless GREENHOUSE GAS

#15
Front (Question)

Carbon Monoxide (CO) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

HIGHLY TOXIC, colorless and odorless

#16
Front (Question)

Nitric Oxide (NO) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

Colorless and odorless precursor of tropospheric ozone

#17
Front (Question)

Nitrogen Dioxide (NO2) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

BROWN fume

#18
Front (Question)

Sulfur Dioxide (SO2) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

precursor to sulfuric acid (acid rain)

#19
Front (Question)

Particulate Matter (PM) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

Two major classes: PM2.5 + PM10 FINE PARTICLES

#20
Front (Question)

Aerosols (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

Chemical similar to PM in size e.g. Ammonium Nitrate (NH4NO3)

#21
Front (Question)

Mercury (Hg) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

discharged from coal burning exists in the form of CH3Hg

#22
Front (Question)

Lead (Pb) (Primary Outdoor Pollutants from Fossil Fuels)

Back (Answer)

formerly a major Pollutant from gasoline combustion

#23
Front (Question)

Carbon Dioxide (CO2) (Primary Indoor Air Pollutants)

Back (Answer)

colorless and odorless - usually from cooking

#24
Front (Question)

Carbon Monoxide (CO) (Primary Indoor Air Pollutants)

Back (Answer)

HIGHLY TOXIC formed when burning w/out sufficient oxygen
