Chemistry Review ~ Air Pollution

What is smog?

• Heavy air

• Smoke

• Fog or haze combined with smoke or other air pollution

• Heavy fog

Smog can cause

• reduced visibility

• irritation in the eyes and lungs of people

• damage to materials

• all of these

Automatic Monitoring is collected how?

• Collects pollutants onto a filter that is sealed and is tested in a lab

• Machines measure a single pollutant's concentration hourly at a specific site

• Light waves measure the concentration of several pollutants ast once

• Air is pumped through a collector for a known period of time and tested in a lab.

Active Sampling is collected how?

• Collects pollutants onto a filter that is sealed and is tested in a lab

• Machines measure a single pollutant's concentration hourly at a specific site

• Light waves measure the concentration of several pollutants ast once

• Air is pumped through a collector for a known period of time and tested in a lab.

Remote Open Path Monitoring is collected how?

• Collects pollutants onto a filter that is sealed and is tested in a lab

• Machines measure a single pollutant's concentration hourly at a specific site

• Light waves measure the concentration of several pollutants ast once

• Air is pumped through a collector for a known period of time and tested in a lab.

Passive Sampling is collected how?

• Collects pollutants onto a filter that is sealed and is tested in a lab

• Machines measure a single pollutant's concentration hourly at a specific site

• Light waves measure the concentration of several pollutants ast once

• Air is pumped through a collector for a known period of time and tested in a lab.

The EPA classifies air pollutants into which two categories?

• Hazardous and Safe

• Safe and Toxic

• Primary and Secondary

• Criteria and Hazardous

Which of these is NOT a primary pollutant?

• Smog

• SO₂ (sulfur dioxide)

• CO (Carbon monoxide)

• Particulate Matter

What is air pollution?

• Pollen, dust, gases

• Chemicals in the water

• Industrial pollution

• Any harmful substance that builds up in the air

How does air pollution move during thermal inversion?

• Thermal inversion makes pollution very still

• There is no pollution during thermal inversion

• Pollution travels very fast in cold air
