Air Quality indicators for 2011 now available from DEFRA


Air quality statistics in the UK during the period 1987 – 2011 are now available from a provisional report released by The Department for Environment, Food and Rural Affairs (DEFRA). DEFRA published its statistical release as an early indication of the final results which will be made available in April this year.

The report utilises particulate matter (PM10) and ozone (O3) as indicators of UK air pollution levels since these pollutants are considered the most detrimental to human health. The statistical release also covered the number of days when air pollution was ‘moderate or higher’ for any one of the following pollutants often investigated by REC’s air quality team: carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3), particulate matter (PM10) and sulphur dioxide (SO2).

Main conclusions to the air quality results

  • Urban background and roadside particulate pollution has improved in the long-term but has shown little change since 2007.
  • Urban background ozone pollution has increased in the long-term since 1987.
  • Rural background ozone pollution has shown no clear long-term trend and has changed little recently.
  • Days of moderate or higher air pollution in urban areas have decreased in the long term but increased in 2011 compared to 2010.
  • Days of moderate or higher air pollution for rural areas have shown no clear trend but increased in the last year.

The conclusions mirror REC’s findings on air quality, with medium term improvements reducing or reversing in recent years.
