Does Hillingdon carry out any air quality monitoring?
There is one Government-owned air quality continuous monitoring station, in West Drayton. This monitors for nitrogen dioxide, fine particulate matter, ozone, sulphur dioxide and carbon monoxide. Hillingdon Council own and operate another two continuous air quality monitoring stations, one in Hillingdon and another in South Ruislip. In addition to the continuous monitoring data Hillingdon also monitors for nitrogen dioxide via the use of passive diffusion tubes. These are placed at sites around the borough on a monthly basis. Results from these show long term trends in nitrogen dioxide levels as opposed to daily averages. Results from all these monitors are available from the air quality data section of this web site.
