AP Environmental Science Air Pollution

Nitrogen oxides (NO_x) are:

• a yellow-brown gas that contributes to photochemical smog

• a colorless and odorless gas that binds to hemoglobin in blood 

• a colorless and odorless gas that damages the lungs

• a reactive gas produced, in part, by photochemical reaction of sunlight  with various air pollutants

Which is an anthropogenic source of nitrogen oxides?

• Nuclear fission

• Combustion of natural gas

• Volcanic eruptions

• motor vehicles

A thermal inversion, which can lead to serious pollution events, occurs when

• warm air close to the surface is blanketed by a layer of cool air that traps pollutants.

• cool air close to the surface is blanketed by a layer of warm air that traps pollutants

• warm air rises, taking pollutants with it.

• cool air rises, taking the pollutants with it

Ozone is a natural component of the Earth’s stratosphere as well as an element of photochemical smog. Ozone also can be an indoor air pollutant. Sources of ozone in homes or offices include:

•  combustion of fossil fuels

• household solvents and cleaning fluids

• photocopying machines, printers, and other high-voltage electrical equipment  

• electrolysis of tap water
