“…Snow cover is an important source of data for environmental pollution studies due to its accumulation of atmospheric dust particles. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] During a snowfall, snow captures gaseous substances and solid particles suspended in the atmospheric air. When the snowfall stops, snow cover collects dry precipitation of particles and dust from the atmosphere.…”

X-ray fluorescence method was proposed for a determination of major elements in samples of snow cover solid phase collected in the urban areas of the Irkutsk region near aluminum smelter and combined heat and power plant. The limitation of the analyzed sample mass, which in some cases does not exceed 50 mg, as well as the features of the elemental composition (high Al and low Si contents) require a special methodological approach to quantitative elemental analysis. Due to the lack of matrix-matched certified reference materials, the calibration set includes certified reference materials of igneous and sedimentary rocks as well as aluminum ore samples. Results of X-ray fluorescence method were compared with the results obtained by reference methods including atomic absorption, atomic emission and spectrophotometry methods. It showed that it is necessary to use samples of snow cover solid phase analyzed by reference methods as a calibration set for X-ray fluorescence analysis, which ensures the quantitative determination of major elements (Na, Mg, Al, Si, P, K, Ca, Ti, Mn and Fe). These elements are important for environmental pollution investigation. Al was discovered as a main pollutant produced by aluminum smelter, Si, Ca, Ti, Mn, and Fe -by combined heat and power plant.

“…Snow samples were collected from Irkutsk region urbanized territories: Shelekhov city and its suburbs, where the main sources of air pollution are aluminum smelters, combined heat and power plants, as well as roads and railroad lines. [28][29][30][31][32] The sampling scheme is presented in Figure 1. It was drawn up taking into account the physical and geographical conditions, including the wind rose, the location of industrial enterprises, and the terrain.…”

Investigation of snow cover solid phase using total‐reflection x‐ray fluorescence method for an assessment of the environmental pollution

et al. 2023

Snow cover is an important source of data for the study of environmental pollution due to its ability to accumulate atmospheric dust particles. A total reflection x‐ray fluorescence method (TXRF) was applied to assess the concentration levels of potentially toxic elements (As, Pb, Zn, Ni, Cu, Cr, V, Mn, and Sr) in samples of snow cover solid phase collected in suburban areas of the Irkutsk region with industrial activity. Suspension was chosen as an optimal sample preparation procedure for solid phases of snow samples obtained after melting and filtration. Results were compared with those obtained by wavelength‐dispersive x‐ray fluorescence spectrometry and atomic absorption spectrometry. Precision of TXRF results expressed by repeatability values was not exceeded 15% (n = 3) for most of the elements, and the trueness of the TXRF method expressed by recovery values was in the range of 87%–115% for concentration levels of 5.0–350 μg/g. Forty samples of snow cover solid phase were analyzed by TXRF method and results were compared with the background values. The investigation showed low contamination of the studied area by Pb, Cu, V, Mn, and Sr, medium contamination by Ni, As, and Cr, and high contamination by Zn. TXRF is advantageous in being rapid, cost‐efficient, and simple and can be used as a promising method for an assessment of environmental pollution.

“…This article discusses the development of the TXRF and WDXRF techniques for the complex study of compositions of pine needles and soils as indicators of industrial pollution. Environmental studies were already led on the investigated area [26,[51][52][53][54][55][56][57][58] however, in this work a strategy based on X-ray methods has been developed.…”

X-ray fluorescence analysis was applied to assess the ecological state of the area potentially polluted by emissions of the aluminum industry and heat power engineering. Soil and pine needle samples were collected in areas with industrial activity and analyzed using wavelength-dispersive X-ray fluorescence (WDXRF) and total-reflection X-ray fluorescence (TXRF) techniques. Both techniques were validated using the matrix-matched certified reference materials. Different sample preparation procedures, such as fusion and pressing for WDXRF and acid digestion and suspensions for TXRF as well as quantification approaches (the external calibration for WDXRF and the internal standard for TXRF) were applied according to the features of the analyzed samples. The rock-forming oxides (Na2O, MgO, Al2O3, SiO2, P2O5, K2O, CaO, TiO2, MnO, and Fe2O3) and trace elements (V, Cr, Ni, Cu, Zn, Rb, Sr, Y, Ba, and Pb) were quantified in soils, as well as several elements (Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, Pb, and Ba) were quantified in pine needles. Comparing the results of soils and pine needles analysis with the regional background values indicated a significant contamination pollution level of the studied area.
