The City of London Corporation added a monitoring site, City of London 8, to the London air quality network at the end of May 2009. It monitors PM₁₀ particulate by TEOM.

The site is in a roadside location in the south of the Corporation area on Upper Thames street, just below London Bridge and is situated by a heavily trafficked road. This site joins two other roadside and two background continuous monitoring sites in the City of London.

Due to the positioning of the site by a busy road, under a bridge, that experiences frequent congestion it is expected to detect elevated PM₁₀ from traffic. Within the City of London there is frequent demolition and construction work. While the PM₁₀ measured at Upper Thames street is expected to be mostly from road traffic it may also be influenced by local construction.

Historic data from 5 April 2007 to 25 May 2009 will shortly be available for download from our website.
