The Investigation of Air Pollution Standing Conference (IAPSC) is a non-statutory consultative body providing a forum for discussion and information exchange, on air pollution and related issues. IAPSC´s original role was to help in the co-ordination of collaborative air quality monitoring, and the analysis of data resulting from investigations carried out principally by local and central government. However, since then IAPSC has widened its interest and membership, and now provides an important interface between the various organisations involved in the assessment and control of air pollution, measurement and effects.
