The latest Devolved Administrations Air Quality Pollutant Inventories report and data have been published and can now be downloaded.
The changes announced on 7th December 2011 by Defra (see previous news item) have now been implemented on this website.
Latest air quality data and bulletins will now present results according to the new DAQI which includes PM2.5 particle measurements for the first time.
Details of how the new DAQI is used is now available.
The Committee on the Medical Effects of Air Pollutants (COMEAP) was asked by Defra and the Devolved Administrations to review the Air Quality Index to ensure that it is fit for purpose given developments in the field of air quality. The current index has been in operation essentially unchanged for a period of around 12 years. COMEAP published the report Review of the UK Air Quality Index in June 2011. Defra and the Devolved Administrations have considered the report recommendations and will implement several changes, following consultation with index users. The implementation of the new index, to be renamed the Daily Air Quality Index (DAQI), is described in this letter.
