Air pollution data

Air pollution data is collected across Westminster.   Currently two of the Council's monitoring sites are Government sponsored. These are in Marylebone Road opposite Madame Tussauds (London Marylebone) and in Horseferry Road, Victoria (London Westminster).

London Marylebone Road is often referred to as the "supersite" since it contains almost every instrument available for monitoring air quality. Its position at the kerbside of one of the busiest roads in central London means that levels of pollutants recorded are amongst the highest in the UK.

London Westminster in on a much less busy road and is designated as an urban background site. Pollution levels here tend to be close to the various objective levels.

There is a sampler in Oxford Street collecting PM10 (particulates) data. 

Pollution data for Westminster and other London boroughs is available from the Environmental Research Group at Kings College, London www.londonair.org.uk.
