Air Pollution Review

For each of the criteria pollutants shown in the table below, fill in their abbreviation, a physical property, and the biggest source.

Groups:

(a) Sulfur Dioxide

,

(b) Nitrogen Oxides

,

(c) Carbon Monoxide

,

(d) Particulates

What season are ozone action days most likely to be declared?

• Summer

• Spring

• Winter

• Fall

What would you expect the pH of normal rainwater to be? What about acid rain?

c

b

a

Acid Rain

Pool Water

Rain Water

How does acid precipitation cause environmental damage?

• • Erodes limestone structures.

• • Leaches aluminum from soils into surface waters.

• Burns away leaves on trees

• • Lowers the pH of surface waters.

• Melts all plastics

For each of these secondary pollutants, explain what primary pollutants react to form them.

Groups:

(a) Ground-level ozone

,

(b) Acid Precipitation

• VOC's

• Nitrogen Oxides

• Sulfur Dioxide and Nitrogen Oxides

Explain the difference between ground level ozone and the ozone layer.

• Ground level ozone is a secondary pollutant. The ozone layer is in the thermosphere.

• Ground level ozone is a primary pollutant. The ozone layer is in the mesosphere.

• Ground level ozone is in the stratosphere. The ozone layer is a secondary pollutant.

• Ground level ozone is a secondary pollutant. The ozone layer is in the stratosphere

How does the ozone layer benefit us?

• It blocks lasers from aliens

• It blocks meteors

• It blocks some of the ultraviolet light from the sun.

• It blocks radio waves from other planets
