Origin analysis of PM10 and its ingredients

Particulate matter can be transported over several hundred kilometres, leading to an increased load even far from their place of origin. The extra-alpine area of Austria — examined the cities of Vienna, Linz, Salzburg and Graz — is reached by long distance transport of dust from large emitters and cities in Eastern Central Europe. In addition, regional pollutant accumulation plays an important role. The contribution of long-distance transport to the urban background pollution of fine dust lies between 15 and 45 % in the extra-Alpine cities of Austria, and between 30 and 45 % of the regional accumulation. The main regions of origin are Romania, Northern Serbia, Hungary, Slovakia, Poland, Czech Republic and Slovenia.
