A sample of water upstream from the same river

Components of photochemical smog graph - 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.

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 location to obtain a water sample from to determine if the paper plant is affecting the acidity of the river?

Immediately downstream from the paper plant

Noise Exposure and Public Health Which of the following best describes why the authors do not claim that noise exposure induces birth defects in humans?

There is insufficient evidence to support that noise exposure induces birth defects in humans.

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.

Noise Exposure and Public Health Which of the following best describes why the authors claim that noise exposure will be a major health problem in the twenty-first century?

There is sufficient evidence to support that noise exposure negatively impacts the immune system.

Vehicular emissions in the United States bar graph- 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.

air pollution by region bar graph - 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

thermal inversion over urban centers chart- In the figure above, the letters A, B, and C represent the different thermal layers present in an inversion. Which of the following shows the correct sequence of thermal layers as one moves vertically upwards from the surface of Earth?

cool sea breeze, warm, cool

Scientists have been monitoring CO2 in the atmosphere from Mauna Loa in Hawaii since 1958. Which of the following units is used by scientists to measure CO2 in the atmosphere?

parts per million

Components of photochemical smog graph - Which of the curves on the graph depicts the concentration of ozone, which requires sunlight to form?

C

air pollution by region bar graph - 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.

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

Install electrostatic precipitators at the plant.

Random samples in different buildings dot plot- EPA 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 EPA action level.

Noise Exposure and Public Health Which of the following best describes why the authors claim that reducing noise exposure is currently more of a public policy problem than a scientific problem?

Most public health impacts of noise were already identified in the 1960s.

atmospheric layers in a thermal inversion picture- Based on the layers in the diagram, which of the following best explains why a thermal inversion tends to concentrate pollutants in the air layer closest to the Earth's surface?

The air layer closest to the Earth's surface is denser than the layer above it

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

projected changes in the atmospheric pollutants in Canada- 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.

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

atmospheric layers in a thermal inversion picture- If the air layers in the diagram were relabeled to illustrate normal atmospheric conditions, the correct labeling from the air layer closest to the Earth's surface to the one farthest from the Earth's surface would be

warm air, cool air, cooler air
