Lead
Of the following cities, which regularly experiences the worst levels of photochemical smog that is enhanced by thermal inversions?
Los Angeles, California
Which of the following best explains the pattern in NO concentration?
NO is produced by rush-hour traffic and is quickly oxidized in the atmosphere.
Which of the following is a common component of photochemical smog and is a reddish-brown gas with a pungent odor?
Nitrogen dioxide, NO2
Consumers who get their electricity from coal-fired power plants are not paying the true cost of energy production in their monthly utility bills. Which of the following is true about utility bills for these consumers?
The bills do not include public health costs, such as those associated with air pollution.
If technology that reduces the hydrocarbon concentration had been utilized, which of the following would have been the most likely result?
The concentration of O3 would have been lower.
The majority of atmospheric mercury is produced by
coal-burning power plants
The three main anthropogenic sources of gaseous air pollutants in the United States are
industry, transportation, and energy production
Ground-level ozone in most major United States cities results primarily from
motor-vehicle exhaust
Smoke from forest fires is most likely to affect air quality over larger areas for many days when
smog is produced due to chemical reactions in the atmosphere
