During the 2006/2007 and 2007/2008 heating periods ambient PM10 concentrations as well as inorganic and organic dust components were measured simultaneously at up to eight sampling sites in and near the city of Augsburg. Based on the emission factors the contribution of primary particles from wood combustion to ambient PM10 concentrations was calculated in a chemical mass balance. In the city centre at the traffic-related site in winter 2007/2008 3.4 µg/m³ (9.2 %) of the total PM10 originated from wood combustion particles on average (range 0.2-15.2 µg/m³, 2-30 %).

About 50 % of the PM10 originated from local wood combustion, 50 % of the PM10 from wood combustion beyond the urban area. The results showed that the concentration of particles from wood combustion were up to 3.7 µg/m³ higher in a residential area with high density of stoves than in the city centre (up to a total concentration of 9 µg/m³ in the daily average).
