What are the UK Air Quality Strategy Objectives for the pollutants shown on the 3D map?
There are separate Objectives for each pollutant that should be achieved by 2005. In each case these objectives are coloured red in the 3D maps. By 2005 the annual mean nitrogen dioxide concentration should be less than 40 g m-3. For PM10 particulate there are two objectives shown; the annual mean concentration should be less than 40 g m-3 and also mean PM10 particulate concentration should exceed 50 g m-3 on more than 35 days per year.
