Immediately downstream from the paper plant

Which of the following would be the most effective plan for the manager to propose to the city?

Install electrostatic precipitators at the plant.

Which of the following sources should be examined in a study to determine the impact of a geologic source on levels of CO2 in the atmosphere?

Volcanoes

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. Which of the following conclusions can be drawn from the data presented in the graph?

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.

The graph below depicts the various components of smog for a densely populated urban area in the Northern Hemisphere. Each plotted line (AA, BB, CC, and DD) is a different component of smog. Which of the different components of smog depicted in the graph are most likely released from automobile exhaust?

A and B

A paper company located on the banks of a river discharges its treated wastewater into the river. Which of the following would be the best control group to evaluate the treated wastewater from the paper company?

A sample of water upstream from the same river

The graph below depicts the various components of smog for a densely populated urban area in the Northern Hemisphere. Each plotted line (A, B, C, and D) is a different component of smog. Which of the curves on the graph depicts the concentration of ozone, which requires sunlight to form?

C

The graph below depicts the various components of smog for a densely populated urban area in the Northern Hemisphere. Each plotted line (A, B, C, and D) is a different component of smog. The data that were used to create this graph were collected in the winter. Which of the following best describes how the graph would be different if the data were collected in the middle of the summer?

Concentrations for component C would be higher throughout the graph.

The Environmental Protection Agency (EPA) of the United States recommends taking corrective measures to reduce exposure to radon gas. The EPA has set an action level of 4pCiL 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?.

Location A has the greatest need for remediation because the radon levels in the building are the highest and exceed the EPAEPA action level.

Scientists have been monitoring CO2CO2 in the atmosphere from Mauna Loa in Hawaii since 1958. Which of the following units is used by scientists to measure CO2CO2 in the atmosphere?

Parts per million

A paper company located on the banks of a river discharges its treated wastewater into the river. Which of the following water quality indicators should be measured to best determine if the wastewater is increasing the acidity of the river?

The amount of hydrogen ions

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?

The plan supports phasing out traditional coal power plants and transitioning to sources like hydroelectricity, wind, and solar power.

A student is setting up a model to study the carbon cycle and natural sources of carbon dioxide. They create a microenvironment that contains soil, leaf debris, an earthworm, heterotrophic bacteria, and a sun lamp. What natural source of carbon dioxide and major metabolic process was left out of the model?

There is no representation of photosynthesis in the model environment.

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 ?

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.

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. Which of the following activities would most likely account for the levels of indoor air pollution in India and sub-Saharan Africa, as shown in the graph?

Use of biomass fuel sources such as wood and charcoal for cooking
