Monitoring of pollution levels

Certain air pollutants are routinely monitored to assess levels of pollution across the borough. The monitoring strategy has been developed and adapted over the years to prioritise pollutants which have been identified to have most risk of breaching the air quality objectives.

The whole of Sandwell has been declared as an Air Quality Management Area for Nitrogen Dioxide (NO2) because there are several areas of the borough where pollution levels were found to be above an acceptable concentration.  These areas have been designated as ‘priority zones’ for improving air quality.

Nitrogen Dioxide is measured on a monthly basis using diffusion tubes which are a simple and inexpensive method of measuring air quality. The results are averaged over a year and then compared to the Government's Air Quality objective of 40 microgrammes per cubic metre (µg/m3).

Although automatic monitoring stations provide more detailed real-time data, these are more expensive to purchase and maintain. Consequently, there are fewer of these used by the council.

Sandwell Council’s air quality diffusion tubes, automatic monitoring stations and priority zones can be viewed in an interactive map.  

Find up-to-date information on local air quality

The West Midlands Combined Authority (WMCA) now provides a regional air quality monitoring website called 'Clean Air' where you can explore up-to-date information about pollution levels across the West Midlands. The site offers interactive maps, real-time data on key pollutants like nitrogen dioxide (NO₂) and fine particulate matter (PM2.5), and insights into how air quality varies by location and time. You’ll also find resources explaining how air pollution affects health and what actions are being taken to improve air quality across the region. It’s a great way to stay informed and see how Sandwell fits into the wider regional picture. Just click here to visit the WMCA Clean Air Website.
