Which policy most directly reduces human exposure to secondary photochemical smog in urban areas?
A
Reducing NOx and VOC emissions from vehicles and industry, limiting ozone formation and related respiratory health impacts during sunny days.
B
Increasing coal combustion efficiency, which raises combustion temperatures and reliably eliminates ozone precursors in exhaust streams.
C
Expanding leaded gasoline use, because lead scavenges radicals and prevents ozone formation in the lower atmosphere.
D
Adding more indoor carpeting, which absorbs ozone outdoors and prevents it from reaching human lungs in city neighborhoods.
