The population of a city is growing. City officials want to monitor air quality to minimize negative impacts from the increased population.

Question

Which three procedures should the city use for the air quality monitoring system?
A. Install sensors in a variety of locations around the city.
B. Compare collected data to long-term baseline levels of key pollutants.
C. Collect data systematically at the same times of day and from the same locations.
D. Collect data only during times that people are most likely to participate in outdoor activities.
E. Use sensors that start recording data when air pollutant concentrations rise above healthy levels.

Answer 1

To effectively monitor air quality and minimize negative impacts from the increased population, the city should use the following three procedures:

A. Install sensors in a variety of locations around the city.
This will provide a comprehensive understanding of air quality across different areas, capturing variations due to localized factors (e.g., traffic patterns, industrial activities).

B. Compare collected data to long-term baseline levels of key pollutants.
This comparison is essential for assessing whether air quality is improving or declining and for understanding trends over time.

C. Collect data systematically at the same times of day and from the same locations.
Consistency in data collection allows for accurate comparisons and trend analysis, helping to identify patterns and variations in air quality.

Using these three procedures will create a robust air quality monitoring system that can adapt to changes in population and pollution levels.
