Nitrogen dioxide is monitored by the use of diffusion tubes located at 17 roadside locations across South Bucks. GMSS laboratory analyse the tubes on behalf of South Bucks and provide an average ambient concentration of Nitrogen Dioxide for the period that the tube is located at the monitoring point. South Bucks commissioned a new air quality monitoring station in January 2001. The air quality station located adjacent to the M25 motorway monitors current real time Nitrogen Dioxide levels. Data from the air quality monitoring station is downloaded by Officers everyday. South Bucks District Council wish to tackle the pollution issues head-on. As such, we have designated an Air Quality Management Area (AQMA) along the M4/M25&M40 corridors. The designation of an AQMA allows us to focus our attention on those areas in the District where air quality is at its lowest. Within an AQMA, local measures can be implemented in order to achieve the objective levels set for all pollutants. The boundaries of the AQMA follow the predicted areas of exceedence adjacent to the motorways but do not simply outline the ‘Hot Spots' where public exposure is predicted. The choice of a corridor allows more flexibility in terms of the development of actions to improve air quality within the District. The location of the AQMA boundary does not represent a distinction between areas of good and poor air quality. The health risks of living or working within the AQMA may be statistically higher, relative to those living outside, however, those living outside the area are just as likely to suffer the effects of poor air quality.. South Bucks District Council  also continues to monitor NO2 and PM10 at the continuous monitoring station in Gerrards Cross, and to monitor NO2 at locations throughout the district. The data recorded are used to produce our annual air quality reports as required by the National Air Quality Strategy. The findings of the most recent reports show that air quality in the district is generally good. Some exceedences of the Air Quality Objective for NO2 have been noted, but primarily these are only within the existing AQMA. The District is subject to some major infrastructure projects from 2016 onwards e.g. HS2 and the Council is working to ensure that air quality issues are adequately dealt with by the scheme promoters.
