Yes, we monitor levels of nitrogen dioxide (NOx), which is a key pollutant from vehicle exhausts. We use a network of around 90 diffusion tubes, which are small plastic tubes that can be attached to lamposts and road signs, and are collected and changed over once a month. The results are presented in our most recent annual status reports, and are reviewed periodically.
You can view the location of current and historic NOx tube monitoring, as well as a summary of previous annual results, on our interactive map. You can also access the East Riding of Yorkshire Council air quality portal to view and download data from our Zephyr monitors
In addition to the NOx tube surveys, we have a network of seven automatic monitors measuring nitrogen dioxide, nitric oxide, ozone and particulate matter (PM1, PM2.5 and PM10). We have also previously used permanent monitoring stations located in Beverley, Bridlington, Goole, and Preston, to provide more detailed information on air quality in our area.
