How does carbon monoxide affect human health?

• It irritates the throat and air passages.
• It interferes with the body’s ability to deliver oxygen to cells.
• It helps the respiratory system function more efficiently.
• It depletes ozone, causing greater exposure to the sun’s rays.

A(n) _____ can trap smog close to the surface. It happens when a layer of cool, dense air stays near the ground and under a layer of warm air.

• acid deposition
• temperature inversion
• convection current
• air mass

• 7
• 12.6
• 4.6
• 9.6

Pollutants are removed or changed chemically before they leave factory smokestacks by a(n)

• chlorofluorocarbon
• catalytic converter
• inversion
