Abstract

A comparison of various averaging techniques to calculate the European Average Exposure Indicator (AEI) for particulate matter in ambient air has been performed. This has been done for data from seventeen sites around the UK for which PM10 mass concentration data is available for 1998-2000 and 2008-2010 inclusive. The results have shown that use of the geometric mean produces significantly lower AEI values within three-year periods and slightly lower changes in the AEI value between three-year periods than the use of the arithmetic mean. The use of weighted means in the calculation, using data capture at each site as the weighting parameter, has also been tested and is proposed as a useful way of taking into account the confidence of each data set.
