Air Quality Management Areas

Air Quality Management Areas are defined geographical areas where air pollution levels are, or are likely to, exceed national air quality objectives at relevant locations (where the public may be exposed to harmful air pollution over a period of time e.g. residential homes, schools etc.).



Within Slough there are four Air Quality Management Areas (AQMAs) declared due to breaches of the annual mean concentrations for nitrogen dioxide (NO2) of 40µg/m3. Details of the existing AQMAs in Slough can be found on this page and more detailed maps can be found on the DEFRA Website - AQMAs interactive map.
