Question 2: What are the challenges in using satellite remote sensing for air quality monitoring?

Which action should you take?

Choose only one option

Limited spatial resolution, atmospheric interference, and lack of ground truth validation for specific pollutants

The inability to detect particulate matter accurately

Lack of global coverage for air quality monitoring

The high cost of data access and processing

Question 3: Under the Clean Air Act, which type of air pollution source requires a Title V permit?

Which action should you take?

Choose only one option

Major sources of air pollutants that have the potential to emit significant levels of pollutants

Small local sources of pollution that exceed the threshold limits

Mobile sources of pollution like trucks and buses

Residential buildings with heating systems

Question 4: When conducting an EIA for an industrial project, which of the following is a critical factor to include in the air quality section?

Which action should you take?

Choose only one option

Financial estimates for the project's air quality compliance

Average public health outcomes from similar projects

Modeling of emission sources and ambient air quality data

Data from industrial equipment sales for emissions forecasting

Question 5: What is the primary difference between passive and active air sampling techniques in air quality monitoring?

Which action should you take?

Choose only one option

Passive sampling uses a chemical absorbent, while active sampling uses a pump to draw air

Active sampling is slower than passive sampling

Passive sampling is only used for particulate matter monitoring

Active sampling is more cost-effective compared to passive sampling

Question 6: What is the importance of Air Pollution Control Technology under regulatory frameworks?

Which action should you take?

Choose only one option

It helps industries comply with emission standards set by the EPA or other governing bodies

It monitors only the emissions from transportation sources

It helps in reducing water pollution levels in industrial settings

It increases emissions from power plants
