Map of automatic monitoring stations
Please note: we are currently unable to display all the data from the monitoring stations because of a communications fault, however, all analysers continue to operate as normal
We use high-tech analysers to monitor air quality at a number of roadside, industrial and background locations. Select an icon to display current air pollution readings and the relevant health advice. There is also a third-party monitoring station in Helsby, which collects data for particulate matter, metals and dioxins. Results for this site are available on the Air Quality England website.
