As part of its duty to monitor the quality of the air in Dudley Metropolitan Borough, the council continuously monitors, and records as 15 minute averages, the levels of a range of common pollutants at its automatic monitoring stations.
Levels of these pollutants may be presented in terms of “Bandings” (Low, Medium, High or Very High), with “indices” (1 to 10) indicating the level within each band. High or very high levels can affect the elderly, asthmatic or very young. A full explanation is also available online.
Up to date information on Air Quality including the current index are available from the UK National Air Quality Information Archive.
