5. Pollution monitoring
The pollutants monitored daily in Stockport are NOx (Oxides of Nitrogen) and PM10's (Particulates). The main source of these pollutants is road transport.
Ambient air quality is monitored using both active and passive methods. We currently have one active monitoring station which is a roadside site located along the A6 in Hazel Grove.
This equipment measures pollution constantly and provides air quality data every few minutes.
