In both developed and rapidly industrialising countries, the major historic air pollution problem has typically been high levels of smoke and sulphur dioxide arising from the combustion of sulphur containing fossil fuels such as coal for domestic and industrial purpose.
The major threat to clean air is now posed by traffic emissions. Petrol and diesel-engined motor vehicles emit a wide variety of pollutants, principally carbon monoxide (CO), oxides of nitrogen (NOx), volatile organic compounds (VOCs) and particulates (PM10), which have an increasing impact on urban air quality.
There are currently three monitoring stations located within Dudley Borough which are used for monitoring a range of pollutants including nitrogen dioxide, fine particulates and ozone. Additional weather monitoring stations are also located in Dudley at St James Road and Colley Gate.
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.

The Council uses Diffusion Tubes in order to measure levels of Nitrogen Dioxide (NO2) within the area. These are small plastic tubes which contain a chemical which reacts with NO2 present in the air. The tubes are changed each month and analysed.

An interactive map showing Nitrogen Dioxide (NO2) Diffusion Tubes diffusion tube locations and annual mean nitrogen dioxide concentrations is now available for you to view online.
The map is an interactive geographical information system which allows you to view and inspect map-based information for the Dudley area. Tools are provided to allow you to zoom and pan around the map, and ‘point and click’ to view information about features on the map.
