“…The percent of metal composition in each dust sample was calculated to obtain rapid and suitable quantitative information, and to compare the exposure levels among the different geographical areas of the territory according to a standardized screening approach. 18 Data were entered into an electronic database and analyzed with descriptive spatial analysis using digital maps of the province (see Fig. 2 for spatial distribution of Al, Ca, Cu, Fe, Mn, Si and Zn).…”

Analysis of settled dust with X-ray Fluorescence for exposure assessment of metals in the province of Brescia, Italy

Ferroalloy industries have been active for more than a century in the province of Brescia, Northern Italy. Air emission and water discharge have contaminated the environment in the surroundings of four plants with several metals including manganese. The presence of manganese in this region is especially interesting, because of the observed relationship between manganese exposure and Parkinsonism in a previous epidemiological survey. The aim of this study was represented by an initial screening of metal exposure in this area, using a geographic information system. X-ray fluorescence (XRF) was applied to identify heavy metals in deposited dust samples, collected in representative residential households throughout the province. The results were interpreted through a systematic mapping of all municipal districts of the Brescia province. A more frequent distribution of manganese and other metals was observed in the municipalities where the plants were located and differences in the geochemical and anthropogenic origin of metals were discussed, according to the point sources.

“…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.

“…Исследования и мониторинг состояния почв фиксируют опасный мировой тренд повышения концентрации тяжелых металлов (ТМ). Загрязнение земной поверхности, геологической среды тяжелыми металлами имеет глобальный характер и наиболее остро в зоне освоения недр, на территориях крупных промышленных агломераций, горно-перерабатывающих предприятий, металлургического и топливно-энергетического комплекса [8,13]. В результате на территориях формируются опасные эндогенные процессы, возникают локальные геохимические аномалии с высоким содержанием токсикантов.…”

“…Выявление причинно-следственной связи распределения ТМ и геохимических параметров почв при наличия других реакционноспособных токсикантов обусловливают научный и практический интерес к исследованию этой проблемы. Она является фундаментальной и многоплановой, а отсутствие системных представлений о воздействии комплекса неучтенных факторов на поведение ТМ в техногенно нарушенных почвах и ландшафтах делает подобные исследования весьма актуальными [5,13,14,16].…”

The soil assessment was carried out in the technogenically-affected area of Irkutsk Oblast with the geochemical approach as a key geoecological method using physical and chemical techniques of analysis and ecodiagnostics. Diagnostic signs of the disturbed natural properties of the soil were revealed up to a depth of 40 cm in the profile based on macro- and micromorphometric parameters. The content of heavy metals (HM) – Pb, Zn, Hg, and Cu with an excess of standards was determined, and empirical HM – pH correlations were obtained by statistical clustering of the data array. The contributions of additional factors affecting the chemical element distribution in the soil layer were investigated. Significant soil contamination with sulfates and the possibility of implementing the ion-exchange of HM andfor element immobilization were revealed. It was shown that reactions with sulfates and the influence of pH, HM exchange processes involving mobile K and P can determine the nature of the described chemical element distribution in the multi-factor-contaminated technogenic soil. However, the effectiveness of such types of interaction is different for each metal and also depends on the quantitative ratio of substances and soil characteristics, even under a minor change in pH. Two-parameter correlations of HM distribution in sulfate-contaminated soils confirmed the different degrees of involvement of chemical elements in these types of interactions. The results obtained and the identified factors are of applied significance and can be used as the basis for geoecological differentiation of the contaminated soil, as well as for determining local geochemical fields in the technogenesis zone. Areas of advanced research are related to three-dimensional modeling for a more complete study of the cause-and-effect relationships of geochemical parameters.
