Air Pollution and Human Health

How does the location of Chattanooga, TN make it more susceptible to pollution?

• Its desert location experiences high temperatures, which increases air pollution.

• Its coastal location exposes it to pollution from the sea.

• Its extremely cold location means that the pollution from snow builds up over time.

• Its location on a large, flat plain exposes it to the wind, which carries air pollution.

• Its location in a bowl formed by mountains causes air pollution to get trapped.

Carbon monoxide is dangerous to human health because it

• reduces visibility and contributes to highway vehicle crashes.

• is a respiratory irritant and is a leading cause of asthma.

• bonds to hemoglobin and interferes with oxygen transfer in the bloodstream.

• destroys ozone in the troposphere.

• is a leading cause of acid rain and acid mine drainage.

Large volcanic eruptions have led to a decrease in the world’s photosynthetic activity because of

• particulate matter, which spreads in the atmosphere and scatters sunlight.

• nitrogen oxides, which blocks sunlight from reaching Earth.

• carbon dioxide, which heats Earth and prevents plant growth.

• ozone emissions, which trap heat in the troposphere.

• photochemical smog, which is often released during volcanic eruptions.
