Air Quality Assessment
Bristol has published various assessments of air quality, all of which are available through Bristol City Council's web site (see links).
As a result of these assessments, an Air Quality Management Area (AQMA) has been declared
as shown here.
This AQMA is the area inside which the UK government's objective for annual mean nitrogen dioxide (NO2) in 2005 was not
met.
The most recent air quality assessment - The Updating and Screening Assessment (April 2006) has also highlighted
potential problems with meeting the benzene objective for 2010 and the 15 minute mean sulphur dioxide objective. Both
of these issues will be investigated further in the forthcoming detailed assessment in 2007.
Bristol has a large network of continuous and passive air quality monitors. Many of these have been operating since the early 1990's.
The continuous analysers currently in operation in the city are
shown here.
