Question 1: How does the concept of "significant impact" in an EIA differ from the standard NAAQS compliance requirements?

Which action should you take?

Choose only one option

Significant impact refers to changes in noise pollution, not air quality

Both are equivalent and focus solely on particulate matter levels

Significant impact refers to changes in air quality that exceed health-based standards, while NAAQS compliance is about meeting regulatory limits

NAAQS compliance only concerns mobile sources, not industrial emissions

Question 2: How does the National Ambient Air Quality Standards (NAAQS) impact air quality monitoring in the U.S.?

Which action should you take?

Choose only one option

NAAQS sets limits on pollutant concentrations to protect public health, requiring compliance in monitoring

NAAQS is a voluntary standard for improving air quality

NAAQS applies only to major industrial sources and not to general ambient air

NAAQS only sets recommendations for pollution control without enforcement

Question 3: Which of the following best describes the role of baseline studies in an EIA?

Which action should you take?

Choose only one option

They monitor air quality during the project's construction phase

They focus only on the economic costs of the project

They predict the long-term impacts of the project

They provide an understanding of the existing environmental conditions before the project begins

Question 4: What method would you use to assess the effectiveness of an air pollution control technology?

Which action should you take?

Choose only one option

By estimating pollution reductions based on manufacturer claims

By observing trends in pollutant levels without considering statistical significance

By comparing pollutant concentrations before and after the installation of the control system, using statistical significance tests

By assuming that emissions will automatically decrease after implementation

Question 5: In air pollution control, what is the main advantage of using an integrated pollution control (IPC) system?

Which action should you take?

Choose only one option

It increases the complexity of the treatment process for efficiency

It is cheaper and simpler to operate than individual treatment systems

It combines multiple treatment technologies to reduce pollutant levels more effectively

It reduces the need for real-time monitoring equipment

Question 6: What is the role of statistical process control (SPC) in air quality management?

Which action should you take?

Choose only one option

It standardizes pollutant concentrations for all monitoring stations

It helps monitor and control air quality data trends over time to ensure they stay within acceptable limits

It measures the rate of emissions at industrial facilities

It isolates data from external factors to ensure accuracy
