Air quality monitoring stations in Brent

We currently operate a monitoring network made up of four automatic monitoring stations and diffusion tubes across 45 locations. We use these to keep track of nitrogen dioxide, PM2.5 and PM10.

All four of the automatic stations monitor NO2 and PM10. Two of the monitors also monitor PM2.5. The 45 diffusion tube locations monitor NO2 only. The data collected each year is published in our Annual Status Reports, which are also available to download.
