APES Module 46
An organic pollutant that evaporates at typical atmospheric temperatures and is a
precursor to ozone is
A. carbon dioxide
B. photochemical smog
C. sulfurous smog
D. a volatile organic compound
E. particulate matter - ANS D
\B - ANS B
\Ground level ozone is classified as a pollutant because it reduces lung function ad
A. its concentrations are low but the particle size is high
B. it occurs in the atmosphere only
C. it is entirely anthropogenic in nature
D. it can degrade plant surfaces
E. it is an unstable molecule - ANS D
\Large volcanic eruptions have led to a decrease in the world's photosynthetic activity
because of
A> particulate matter, which spreads in the atmosphere and scatters sunlight
B. nitrogen oxides, which blocks sunlight from reaching Earth
C. carbon dioxide, which heats Earth and prevents plant growth
D. ozone emissions which trap heat in the troposphere
E.. photochemical smog, which is often released during volcanic eruptions - ANS A
\Ozone is formed .in the atmosphere as a result of the combination of nitrogen oxides
(NOx) and volatile organic compounds (VOCs) in the presence of sunlight. This ozone is
A. a secondary pollutant
B. a primary pollutant
C. nitrogen smog
D. photochemical smog
E. particulate matter - ANS A
\Photochemical smog, which frequently exists in major metropolitan areas such as Los
Angeles, consists primarily of
A> fog
B. ozone
C. sulfate compunds
D. carbon particulate matter
E. smoke - ANS B
\Sulfates are considered secondary pollutants because
A. their emissions are difficult to regulate
B. they form more readily at night and in dry areas
C. they result from the transformation of primary pollutants
D. they originate from burning coal
