Ambient Air Quality Monitoring

Ambient Air Monitoring is the systematic, long-term assessment of pollutant levels by measuring the quantity and types of certain pollutants in the surrounding, outdoor air.

Ambient air measurement and monitoring is an integral part of an effective air quality management system. Reasons to collect such data include to:

  • Assess the extent of pollution;
  • Provide air pollution data to the general public in a timely manner;
  • Support implementation of air quality goals or standard;
  • Evaluate the effectiveness of emission control strategies;
  • Provide information on air quality trends;
  • Provide data for the evaluation of air quality models; and
  • Support research (e.g., long-term studies of the health effects of air pollution).

There are different methods to measure pollutant. A developer of a monitoring strategy should examine the options to determine which method are most appropriate, taking into account the main uses of the data, initial investments costs for equipment, operating costs, reliability of systems, and ease of operation.

The locations for monitoring stations depend on the purpose of the monitoring. Most air quality monitoring networks are designed to support human health objectives, and monitoring stations are established in population center. They may be near busy roads, in city centers, or at locations of particular concern (e.g., a school, hospital, particular emissions sources). Monitoring stations also may be established to determine background pollution levels, away from urban areas and emissions sources. Systems are needed to ensure that date are of acceptable quality, to record and store the data, and to analyze the data and present results.
