True
- B
False

Formation of nitrogen in the upper atmosphere
A monitoring report focuses on fine particles with aerodynamic diameters of 2.5 micrometers or less. What particulate-matter category should the report name?
Ground-level ozone is a formed when nitrogen oxides and volatile organic compounds react in .
A region wants to reduce acid deposition caused by emissions from fossil-fuel combustion and vehicles. Which pair of pollutants should it target most directly?
- A
Sulfur dioxide and nitrogen oxides
- B
Carbon monoxide and radon
- C
Ozone and water vapor
- D
Methane and oxygen
Reducing ground-level ozone pollution would necessarily require removing the protective ozone layer in the stratosphere.
- A
True
- B
False
Which outcomes are examples of public-welfare concerns addressed by secondary air-quality standards? Select all that apply.
- A
Damage to crops and forests
- B
A patient's individual asthma diagnosis
- C
Reduced visibility
- D
Protection of buildings and monuments
- E
Effects on ecosystems
What is the name of the preferred indoor-air-quality strategy that eliminates or reduces pollution at its origin, such as stopping indoor smoking or repairing a faulty combustion appliance?
Carbon monoxide is produced by and harms people by reducing the blood's .
Which statement correctly distinguishes primary and secondary National Ambient Air Quality Standards?
- A
A secondary standard protects only people with asthma.
- B
A primary standard is designed to protect public health, while a secondary standard protects public welfare.
- C
Primary and secondary standards differ only in the pollutant measured.
- D
A primary standard controls indoor pollutants, while a secondary standard controls outdoor pollutants.
Explain the pollution-control hierarchy from source reduction through environmental cleanup. Apply the hierarchy to at least two examples from atmospheric or indoor air pollution, and explain why the earlier steps are generally preferred.
Which setting is most likely to experience a photochemical-smog episode?
- A
A cool, dark valley with only elevated radon from soil
- B
A rainy rural area with no nitrogen oxides or volatile organic compounds
- C
A hot, sunny urban region with vehicle emissions of nitrogen oxides and volatile organic compounds
- D
A stratospheric region with high ozone and little air near the ground
Why is ground-level ozone classified as a secondary pollutant?
- A
It is emitted directly from vehicle exhaust in large quantities.
- B
It forms through atmospheric reactions involving nitrogen oxides, volatile organic compounds, and sunlight.
- C
It forms only when sulfur dioxide dissolves in rainwater.
- D
It is produced when stratospheric ozone descends to the surface.
A city experiences calm weather overnight, with warmer air above cooler air near the ground. What is the most likely air-quality consequence?
- A
It increases vertical mixing by causing surface air to rise rapidly.
- B
It converts primary pollutants directly into acid deposition.
- C
It removes particulate matter by causing it to settle immediately.
- D
It suppresses vertical mixing and traps pollutants near the surface.
Which receiving environment would generally be most resistant to ecological damage from acid deposition, assuming similar acid inputs?
- A
A lake or soil system with limestone-rich material
- B
A thin soil layer over granite
- C
A surface-water system receiving no mineral inputs
- D
An ecosystem with only sandy, nutrient-poor soil
A building manager wants to reduce indoor air pollution from a malfunctioning combustion appliance. Which action best follows the recommended control hierarchy?
- A
Installing a filter while leaving the pollution source unchanged
- B
Increasing humidity to dilute indoor pollutants
- C
Cleaning surfaces after pollutants have accumulated
- D
Eliminating or reducing the pollution source itself
Stratospheric ozone and tropospheric ozone have opposite environmental roles: stratospheric ozone is protective, while ozone near Earth's surface is harmful.
- A
True
- B
False
