Air quality management areas

Where the review and assessment process has identified that air quality objectives are not being met, Air Quality Management Areas (AQMA's) may be declared.

Actions taken to improve air quality can be focused on these areas and their success measured by ongoing monitoring and assessment of these specific areas. Currently there are 10 AQMA's in the Southampton. These are:

Air quality management areas Characteristics NO2 levels - as range of 2012 annual means recorded at roadside/ residential facade 5 year trend Annual mean NO2 standard
AQMA 1 - Bevois Valley Road Queuing traffic congestion at junctions 36-52 ug/m3 Reducing slightly 40
AQMA 2 - Bitterne Road West Linear heavily trafficked road in to city centre from the east 34-41 ug/m3 Reducing slightly 40
AQMA 3 - Winchester Road Queuing traffic congestions at junctions 38-45 ug/m3 Reducing slightly 40
AQMA 4 - Town Quay Linear, heavily trafficked road, access to IOW ferries, cruise ships terminals 35-42 ug/m3 - 40
AQMA 5 - (1 of 3)
Millbrook Road and Redbridge Road
Linear heavily trafficked road in to container port, high number of HGVs 35-50 ug/m3 Reducing slightly 40
AQMA 5 - (2 of 3)
Millbrook Road and Redbridge Road
AQMA 5 - (3 of 3)
Millbrook Road and Redbridge Road
AQMA 6 - Romsey Road Queuing traffic congestion at junctions 40 ug/m3 - 40
AQMA 7 - merged with AQMA 5 - - - -
AQMA 8 - Commercial Road Queuing traffic congestion at junctions 44 ug/m3 Reducing slightly 40
AQMA 9 - Burgess Road Queuing traffic congestion at junctions 34-46 ug/m3 Reducing slightly 40
AQMA 10 - New Road Queuing traffic congestion at junctions 40-47 ug/m3 Reducing slightly 40
AQMA 11 - Victoria Road Queuing traffic congestion at junctions 35-43 ug/m3 Reducing slightly 40


All of Southampton's 10 AQMAs have been declared for exceeding the nitrogen dioxide annual mean air quality standard. Source apportionment has shown that road vehicle emissions are the main source of the air pollution.

Pollution levels drop off rapidly from the kerb of busy roads. In general the air quality standard is only exceeded within 10metres or often less from the kerb.

The actions taken to improve air quality in the AQMA's and across the city are described in the Council's Air Quality Action Plan (AQAP), adopted in April 2008.
