Air Monitoring is included in the more general environmental monitoring and involves the observation and analysis of data samples about chemical conditions (PM10, carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide), temperature, mold growth and humidity.
The locations for monitoring systems depend on the purpose of the monitoring itself. Most air quality monitoring networks are designed to support human health objectives, and monitoring stations are established in population centers, especially at locations of particular concern (for example near busy roads, in city centers). But monitoring systems also may be established to determine background pollution levels, so they’re located away from urban areas and emissions sources.
