Air quality management areas
Where the review and assessment has identified that air quality objective are not being met, Air Quality Management Areas (AQMA) may be declared.
Actions taken to improve air quality can be focussed on these areas and their success measured by ongoing monitoring and assessment of these specific areas. Currently there are 10 AQMAs in Southampton.
All 10 of Southampton's AQMAs have been declared for exceeding the nitrogen dioxide annual mean air quality standard. Source appointment 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 10 metres or often less from the kerb.
The actions taken to improve air quality in the AQMAs and across the city are described in the council's Air Quality Action Plan, adopted in April 2008.
