Detail

This is the first report prepared by the Standards Advisory Subgroup (CSAS) of the Committee on the Medical Effects of Air Pollutants. The subgroup was formed in June 2009 when the Expert Panel on Air Quality Standards (EPAQS) was merged with COMEAP.

In 2009, the subgroup was asked by Defra to review the current UK air quality index. Since the air quality index was last revised in 1998, there have been a number of developments in the regulation of air pollution and in the presentation of air quality information, which are reflected in these proposals.
