Air Quality Management Areas identify locations where one or more UK Air Quality objectives have not been achieved. In Wiltshire’s case these are areas relate to locations where the annual mean objective for nitrogen dioxide is being exceeded (40ug/m3). The source is emissions from road traffic & an action plan has been put in place to reduce levels. See also www.wiltshireairquality.org.uk
