SG Indoor Air Pollutants Quiz

Indoor Air Pollutants Quiz Scientists have observed that the health of people living in moderately developed regions, which have developed transportation and industry but lack environmental control measures, is more likely to be affected by urban outdoor pollution than by indoor air pollution. 1. Which of the following conclusions can be drawn from the data presented in the graph? (A) In moderately developed regions such as China and Latin America, an individual’s health is more or as likely to be affected by urban outdoor pollution than by indoor pollution. (B) Developing regions such as sub-Saharan Africa are less affected by indoor air pollution because there is no source of radon in the region. (C) Indoor air pollutants decrease and urban outdoor pollutants increase as countries become more industrialized. (D) The amount of both indoor and outdoor air pollution is directly linked to the size of each region. 2. Which of the following activities would most likely account for the levels of indoor air pollution in India and subSaharan Africa, as shown in the graph? (A) Construction of homes with more efficient insulation and increased ventilation (B) Use of biomass fuel sources such as wood and charcoal for cooking (C) Industrial power plants burning fossil fuels for electrical energy generation (D) Use of chemical pesticides on croplands Indoor Air Pollutants Quiz 3. The Environmental Protection Agency ( ) of the United States recommends taking corrective measures to reduce exposure to radon gas. The has set an action level of for radon gas. The graph below shows radon samples taken from seventeen buildings in California. The radon samples were taken from the air inside the buildings, and the uranium concentrations were sampled from the soil under the buildings. Data points from four of the seventeen building locations are labeled A-D. Which of the following conclusions can best be drawn from the data in the graph? (A) Location has the greatest need for remediation because the radon levels in the building are the highest and exceed the action level. (B) Location has the lowest need for remediation because the radon levels in the building are below the suggested action level. (C) Location (D) has the greatest need for remediation because the radon levels in the soil are the highest. Location has the lowest need for remediation because there is no measurable radon in the air or the soil samples. Indoor Air Pollutants Quiz 4. Canada has proposed an action plan to address climate change and air pollution. The action plan will reduce the impact of greenhouse gases and pollutants on the environment and human health. Which of the following claims about the Canadian action plan is best supported by the data in the graph? 5. (A) The plan encourages the transition from electricity generation from nuclear power to electricity generation from cleaner-burning natural gas. (B) The plan focuses on increasing regulation on installation and maintenance of catalytic converters in vehicle exhaust systems. (C) The plan supports phasing out traditional coal power plants and transitioning to sources like hydroelectricity, wind, and solar power. (D) The plan provides a strategy for reducing the amount of plastic wastes in landfills through the production of long-lasting and durable plastics. ) in Over a three-year period, a city’s environmental protection department measured the particulate matter ( a ten-square-mile area around one of the city’s coal-fired power plants. The annual mean level of measured was over the three-year study period. The National Ambient Air Quality Standard ( ) for is an annual mean level of , averaged over three years. The city instructs the manager of the power plant to propose a plan to aid the city in meeting the for in the area around the power plant over the next ten years. Which of the following would be the most effective plan for the manager to propose to the city? (A) Install catalytic converters at the plant. (B) Install vapor recovery nozzles at the plant. (C) Install electrostatic precipitators at the plant. (D) Burn lignite coal instead of bituminous coal at the plant. Indoor Air Pollutants Quiz 6. Which of the following best explains the cause of the trend shown in the graph for lead emissions in the United States from 1970 to 2011 ? (A) By 1990, all new model cars were equipped with internal fabric filters that effectively filtered car exhaust and reduced lead emissions. (B) Beginning in 1975, The Clean Air Act required new cars to have catalytic converters, which effectively converted the lead found in gasoline to water vapor. (C) New air-scrubber technologies were introduced in the late 1970s that effectively removed lead in the air and converted it into water vapor. (D) Unleaded gasoline was first introduced in 1974, and amendments to the Clean Air Act required cars with the model year 1975 or later to use only unleaded gasoline.
