Our most recent understanding of the formation of tropospheric ozone requires the reduction of atmospheric levels of
A)volatile inorganic compounds.
B)carbon monoxide and volatile organic compounds.
C)nitrogen oxides and carbon monoxide.
D)nitrogen oxides and volatile organic compounds.

Question

Quizplus · Accepted Answer

Tropospheric ozone (ground-level ozone) is formed by chemical reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight. Therefore, the reduction of atmospheric levels of nitrogen oxides and volatile organic compounds is required to limit the formation of tropospheric ozone.
