A6 Air Quality Monitoring System
Environmental Noise Dust Online Monitoring System

The Air Quality Monitoring System (AQMS) is a facility to measure wind speed, direction, other weather parameters, concentration of air pollutants (such as SO2, NOx, CO, O3, THC etc), and particulate matters continuously all year round. Mobile AQMS can also be customized to monitor multiple sites via one system.

Particulate air pollution is defined by the US EPA as an air-suspended mixture of both solid and liquid particles. They are often separated into three classifications; coarse, fine and ultrafine particles. Coarse particles have a diameter of between 10 µm and 2.5 µm and settle relatively quickly whereas fine (1 to 2.5 µm in diameter) and ultrafine (<1 µm in diameter) particles remain in suspension for longer. Keep in mind that due to how the scale is built, PM10 (coarse) also automatically contains PM2.5 (fine) and PM1.0 (ultrafine). Additionally, PM2.5 (fine) contains PM1.0 (ultrafine) as well. To put things into perspective, human hair has a diameter of 50-70 µm and a grain of sand has a diameter of 90 µm.

When someone talks about PM10 they are referring to particles smaller than 10 µm. These particles include dust, pollen and mold spores. Conversely, when someone references PM2.5 they are referring to particles smaller than 2.5 µm. These smaller particles include combustion particles, organic compounds and metals.
