This is a UK Government sustainable development strategy indicator
This is part b of the sustainable development air quality indicator.
In urban areas in 2007, air pollution was recorded as moderate or higher on 24 days on average per site, compared with 41 days in 2006, and 59 days in 1993, reflecting a high degree of variability.
In rural areas, air pollution in 2007 was moderate or higher for 24 days on average per site, compared with 56 in 2006. This figure has varied significantly over time, although there now appears to be a gradually increasing long term trend, mostly due to ozone which causes the majority of the pollution days.
