Information about levels of pollution is available in a variety of formats:
The Environmental Research Group (ERG) of Kings College, London runs the London Air Quality Network on behalf of the London Boroughs and its website provides current data about air pollution levels over London. Users can select the area (London Borough) that concerns them and display information from the monitoring sites. The locations of these sites are denoted by bright green circles, each containing a figure indicating the current pollution level, and when the cursor is passed over each circle the name of that station is displayed.
