All of the following are examples of primary air pollutants except
sulfur dioxide
carbon dioxide
tropospheric ozone
nitrogen oxide
particulates
The greatest emission of sulfur dioxide comes from
on-road vehicles
biofuels
industrial processes
electricity generation
fires
The least amount of nitrogen oxide emissions comes from
on-road vehicles
fossil fuel combustion
industrial processes
electricity generation
fires
The accumulation of tropospheric ozone at night depends mainly upon the atmospheric concentration of
nitrogen dioxide
volatile organics
chlorofluorocarbons
sulfates and nitrates
nitric acid
Under natural conditions the pH of rainfall is closest to
8.5
7.1
5.6
4.5
3.1
The effects of acid deposition include all of the following except
mobilization of metal ions from the soil into surface water
increased numbers of salamanders in ponds and streams
reduced food sources for aquatic organisms
erosion of marble buildings and statues
erosion of painted automobiles finishes and metals
The World Health Organization estimates that over half of the deaths worldwide due to indoor air pollution occur among
children less than 5 years old
elderly people over 65 years old
people who work in office buildings
workers in the smelting industry
workers who manufacture asbestos
Two major factors involved in the conversion of primary pollutants into secondary pollutants are
sunlight and water
sulfates and sunlight
water and volatile organics
nitrogen oxides and sulfates
sulfur dioxide and sulfuric acid
The pollutant least likely to be emitted from a smokestack would be
carbon monoxide
carbon dioxide
ozone
sulfur dioxide
particulates
How might the increased use of insulation in a home affect air pollution?
Some common insulation off-gasses sulfur dioxide
The production of insulation releases large amounts of particulate matter
Increased insulation can create indoor air pollution problems
Insulation provents problems with radon in homes
Good insulation can help prevent sick building syndrome
The EPA identifies all of the following as reasons for sick building syndrome except
faulty ventilation systems
emissions from carpets and furniture
contamination from outdoor air
contamination from molds and pollen
high levels of radon in the basement
Which statement regarding the decreased level of stratospheric ozone is correct?
Increased photosynthetic activity has been measured in the phytoplankton around Antarctica
The largest decrease in the level of stratospheric ozone over the Arctic region occurs between January and April
Although the Montreal Protocol led to a reduction in the use of CFCs, it will have little effect on stratospheric ozone levels in the long term
There is no correlation between the incidence of cataracts and skin cancers and the lower level so stratospheric ozone
The global crop yields of wheat, rice, and corn have increased since the reduction in CFC use
Which is most strongly absorbed by ozone in the statosphere?
UV-A
UV-B
UV-C
UV-B and UV-C
UV-A and UV-B
Natural sources of air pollution include all of the following except
forest fires
volcanic eruptions
waterfalls
dust storms
conifer trees
A thermal inversion
rarely occurs in cities but is common in rural areas
helps remove pollutants from the atmosphere
leads to decreased amounts of ground-level smog
occurs when a warm air layer overlies a cooler layer
occurs when a cool air layer overlies a warmer layer
A polluting compound that comes directly out of the smokestack, exhaust pipe, or natural emission source
Primary air pollutant
Secondary air pollutant
Acid deposition
Trophospheric ozone
A primary pollutant that has undergone transformation in the presence of sunlight, water, oxygen, or other compounds
Primary air pollutant
Secondary air pollutant
Acid deposition
Photochemical smog
A layer of the atmosphere closest to the surface of Earth, extending up to approximately 16 km (10 miles) and containing most of the atmosphere’s nitrogen, oxygen, and water vapor
Volatile Organic Compounds
Tropospheric ozone
Acid deposition
Smokestack scrubber
A buildup of toxic compounds and pollutants in an airtight space; seen in newer buildings with good insulation and tight seals against air leaks
Acid deposition
Asbestos
Radon
Sick building syndrome
An organic compound that evaporates at typical atmospheric temperatures.
Tropospheric ozone
Sulfur dioxide
Volatile Organic Compunds (VOCs)
Particulate matter
Acids deposited on Earth as rain and snow or as gases and particles that attach to the surfaces of plants, soil, and water
chlorofluorocarbons
volatile organic compounds
Acid deposition
gray smog
