Mineralogical and oxygen isotope composition of inorganic dust-fall in Wrocław (SW Poland) urban area – test of a new monitoring tool

We have analysed the mineralogical and oxygen isotope composition of solid inorganic atmospheric particles (SIAP) in Wrocław (SW Poland) to determine potential natural and anthropogenic sources of deposited dust. The mineralogical compositions of SIAP and local soils are very similar and quite typical. Dust sources were attributed to high emission sources (two large coal-fired power generation plants, i.e., "Wrocław and "Czechnica") and low emission sources (mostly small furnaces for home heating). A mullite phase was confirmed in the non-magnetic fraction of high emission dust. The δ18181818
