ABSTRACT
The study was conducted in the area of influence of Mine and Power Plant “Turów” which, through the emission of gaseous and particulate pollutants contribute to soil contamination, among other things by arsenic. The aim of this study was to determine the total content of this metal in samples of anable soils collected in the area of the impact of the above-mentioned emitters. At the same time their grain-size distribution and their physico-chemical properties, as pH and percentage of organic matter were determined. Soils collected from a depth of 0.0 to 0.3 m below ground surface, and from 0.3 to 0.6 m b.g.s. came from the area of direct impact of the mine and power plant (area of Bogatynia) and the region of Zgorzelec ,located out of the direct impact of emitters. Total arsenic content was determined by ICP- AES using a plasma spectrometer Varian Liberty Series II. All soil samples, independently of the place of origin, showed acid pH, and organic matter content in both research areas was higher at a depth of 0.0 to 0.3 m. In accordance with the classification of PTG 2008, soils from the area of Zgorzelec were classified as very light, light and medium (loose sand, loamy sand, sandy loam and light loam), with a high content of sand fraction it was also found. The soils of Bogatynia region were classified as medium and heavy silty (loamy silt and clayey silt), with a high content of silt fraction . Increased levels of arsenic in cultivated soils in the area of influence of the Mine and Power Plant, on the one hand they are connected with its anthropogenic its release during the combustion of coal, and on the other hand it is the influence of physico-chemical properties of soils. It is the reason of increased accumulation of this metal, mostly at a depth of 0.3 to 0.6 m. Significant, 3 times, higher level of this metal was showed in the area of direct impact of Mine and Power Plant “Turów”, compared with the area of Zgorzelec, apart from the depth of their collection. Certainly the great importance for the absorption of the metal may be overlapping in this region, local and cross-border pollution, acidic soils and a higher percentage of organic matter. Grain-size distribution, mainly 4 times higher average percentage of fractions of silt and clay fractions are of great importance.
