APES Chapter 15 QUIZ

Which is NOT a criteria air pollutant?

• Sulfur dioxide
• lead
• carbon dioxide
• particulate matter

a secondary pollutant

• forms in the stratosphere
• is transformed by sunlight or water
• cannot be directly tracked 
• forms primarily from incomplete combustion

Which is a source of sulfur dioxide found in nature?

• forest fires
• lightning
• plant emissions
• volcano

Which size of particulate matter causes the greatest health concern?

• PM2.5

• PM10

• PM100

• PM50

Carbon monoxide

• increases lung cancer rates
• leads to the formation of photochemical smog
• is most problematic in rural areas
• is produced by incomplete combustion

High levels of photochemical smog are due to
   I nitrogen dioxide
  II sulfur dioxide
III VOC's

• I only
• I and II only
• II and III only
• I and III only

Recent increases in acid deposition in the western U. S. are due to

• increased emissions in the U. S.
• decreased precipitation due to climate change
• increased emissions in China
• increased emissions in Europe

Thermal inversions

• increase the rate of smog formation
• trap high concentrations of pollution as ground level
• result in increased levels of acid deposition
• reduce the negative effects of VOC's

Acid deposition forms as a result of 

• nitrogen oxides and photochemical smog
• carbon monoxide and VOC's
• sulfur dioxide and VOC's
• nitrogen oxides and sulfur dioxides

The effects of acid deposition include

• increased cancer rates in aquatic organisms 
• increased pH of lake water
• decreased mobilization of metals
• decreased aquatic biodiversity
