Air quality monitoring

Air Pollution Measurements

We have two machines which measure air pollution continuously. One is outside the RAMM on Queen Street. This measures nitrogen dioxide (NO2), ozone (O3) and particulate matter (very fine dust). The second machine is on Alphington Street. This one only measures particulate matter. Both these machines give us pollution levels for every 15 minutes of the year.

We also have 81 places in the city where we measure nitrogen dioxide using a simple method called a diffusion tube. These just give us the average pollution level for each month. There is a list and map of these measurement sites at the bottom of this page.

Air pollution levels have generally fallen over the last 10 years. Away from busy roads and in typical housing areas the nitrogen dioxide levels meet the standards set by government. Most houses in the city and all schools are these areas. But, there are a small number of places where pollution levels are worse than the standards. These hotspots are along some of the busiest roads into and around the city.

Every year we produce an Annual Status Report which summarises the latest air pollution levels and explains what we are doing to reduce pollution.

If you would like to see the 2018 report please contact us at environmental.health@exeter.gov.uk.
