EVALUATION OF CONTENT OF SELECTED HEAVY METALS IN SOILS OF SHOOTING RANGES

The paper describes analyses of soils taken from open shooting ranges to find pollutants in the form of selected heavy metals. Test samples were taken from closed shooting ranges located in Wloclawek commune. During the investigations the content of following elements was identified: Zn, Pb, Cd, Cu, Ni, Co, Fe, As. The characterization of investigated localizations was also made with evaluation of samples of soils according to the Regulation of the Minister of Environment from 01 September, 2016 on the assessment of ground surface pollution. Studies confirm the relationship occurring between the effects of carried out shooting activities and the degree of accumulation of selected heavy metals elements in the soil of open shooting ranges. Indications show that this is sometimes a very complex issue and if neglected it can cause in the future a serious threat.

Heavy metals in soils and mosses-epiphytes of the Leninsky district of the city Izhevsk

The article presents the results of studies on the assessment of heavy metal pollution of soils and epiphytes in of the city of Izhevsk. Objects of research: soils of near-trunk circles of black poplar (Populus nigra L.) and epiphytic moss of Schreber's pleurotium (Pleurozium schreberi (Willd. Ex Brid.) Mitt.). To assess the pollution, the magnetic susceptibility of soils and mosses was determined, as well as the average total content of heavy metals in the samples under study. The relationship between the content of heavy metals and the magnetic susceptibility of soils and epiphytes has been determined. A correlation was revealed between the total content of Zn, Cr, Fe, V in soils and in mosses, which indicates air pollution of soils.
