There are a total of 33 boroughs and 785 wards (1991 ward data) in London. For nitrogen dioxide there are currently 16 London boroughs and 19 London wards that have monitoring in the national network. For sulphur dioxide there are currently 10 London boroughs and 13 London wards that have monitoring in the national network. For benzene there are currently four London boroughs and four London wards that have monitoring in the national network. Data from different sites are not necessarily directly Comparable due to the different locations of the sites, for example, kerbside, roadside, background and suburban. The data for all the sites within the United Kingdom Automatic Urban and Rural Air Quality Monitoring Network are available from the national air quality Information archive (www.airquality.co.uk).
In addition, a number of London boroughs carry out independent monitoring which is within the London Air Quality Network. Thirty-one boroughs have nitrogen dioxide monitoring, 26 boroughs have sulphur dioxide monitoring and one borough monitors benzene.
