Air quality monitoring and standards in Bromley

For nearly two decades Bromley has been carrying out a rigorous assessment of local air quality in the Borough. We continue to meet our statutory duty under Part IV of the Environment Act 1995 to periodically review and assess the air quality within our area as part of the Government's National Air Quality Strategy. National air quality objectives (AQOs) have been designated for:

  • Nitrogen dioxide (NO2)
  • Particulates
  • Carbon monoxide
  • Benzene
  • 1,3-Butadiene
  • Sulphur dioxide
  • Lead
  • Ozone

Air quality standards in Bromley  

Over the years our monitoring showed AQOs were being met and consequently no action or intervention was necessary. This changed in 2006 when it was established that the AQOs for nitrogen dioxide was unlikely to be met. Consequently in 2007 an Air Quality Management Area (AQMA) was declared.  The AQMA covered the six wards in the north and west of the borough where the AQOs were likely to be breached. The AQMA includes less than a fifth of the borough's area.    

We have produced an Air Quality Action Plan (AQAP) to demonstrate how we, in partnership with the community and other stakeholders, will improve air quality in the Borough. The plan also complements the Mayor of London Air Quality Strategy - Clearing London 's Air.  More information about air quality and air pollution in London can be found on the Mayor of London's website.

Air quality monitoring in Bromley

Air quality monitoring is very expensive and whilst many residents would like monitoring to be carried out in their neighbourhood this is not practical. The approach taken has been to operate a continuous monitoring site to produce data of the highest quality, and supplement this with a significant number of inexpensive diffusion tubes which are exposed for a period of a few weeks. Air quality is then calculated from the emissions which are known to arise from road traffic and other fixed sources such as boilers, incinerators etc and the results are regularly compared with the measured information in order to ensure that the computer modelling is accurate.
