“…This conclusion is compliant with the measurement results of the mass size distribution of EC-containing airborne particles in Katowice in 1989, which showed heavy atmospheric pollution with EC particles, particularly for the range of 1.8-2.5 µm [39]. The finding was also confirmed by the research conducted in Katowice in summer 2012 [14].…”

Ambient particles whose aerodynamic diameters were not greater than 2.5 µm (fine fraction of Particulate Matter; PM2.5) and 1 µm (PM1; sub-fraction of PM2.5) were sampled at three sites in Upper Silesia (Poland): urban background site, rural background site, and urban traffic site. In total, 240 samples were collected between 2 August 2009 and 27 December 2010. The reflectance of the collected PM1 and PM2.5 samples was determined with a digital smoke stain reflectometer. The 24-h courses and seasonal changes of three determined optical parameters for PM1 and PM2.5 (absorption coefficient (a), mass absorption (σ), and mean light reflection coefficient (Rav)) were illustrated and discussed. The mean values of the regional background absorption coefficient (a) were 1.27 × 10 for PM2.5 and PM1, respectively. In Katowice (urban background), the mean absorption levels were 2.37 × 10 1522 the increase in the concentration of the PM2.5-bound sulphates was even higher, which resulted in the relative decrease of the elemental carbon content in this PM fraction in some areas. Consequently, the mass absorption value dropped there as well.

“…While seasonal changes in concentrations and mass-size distribution of suspended dust in the lower troposphere in Upper Silesia have been well documented (e.g. Bajor et al, , 2002Cimander et al, 1998Cimander et al, , 1999Cimander et al, , 2000Manecki 1984;Pastuszka et al, 1989Pastuszka et al, , 1993, the changes in phase composition of particulates are rather poorly known. The purpose of this paper is to document both the seasonal changes in overall dust concentrations in the lower troposphere in the Upper Silesian industrial region and the variations in the mineral composition of the dust.…”

The tropospheric dust loading in Upper Silesia (Poland) shows a steady, annually averaged supply of minerals from natural and anthropogenic sources, industrial dust emitters, domestic heating, transportation, but with superimposed seasonal changes for some dust types. Samples of airborne and deposited particles were collected at monthly intervals between 1996 and 2001 in several cities of Upper Silesia. Dust samples were examined by X-ray powder diffraction, analytical transmission electron microscopy, analytical scanning electron microscopy, and electron microprobe microanalysis. The most common dust included quartz, gypsum, coke, soot, hematite, magnetite, wüstite, bassanite, graphite and various K-, Fe-and Mg-bearing aluminosilicates, in order of decreasing abundance. Minor phases included a-iron, sulphur, sphalerite, halite, sylvite, hercynite, franklinite, baryte, dolomite, ankerite, apatite, olivine and feldspars. Quartz, and specific industrial minerals, e.g. spinels, sphalerite, olivine and iron, occurred throughout the year in almost constant abundances. The amounts of all other dust components show seasonal variations; gypsum, baryte and other sulphates are particularly abundant in winter. In general, minerals related to low-emission sources are abundant in the winter time, while both natural dusts and dust from high-emission sources are predominant during the summer.
