“In the present work, X-ray fluorescence analysis (PortableX-ray fluorescence analyzer SciAps X-Series X-200, USA) is used to determine the elemental composition of plant samples. The method allows qualitative and quantitative analysis of elements using secondary X-rays generated by X-ray irradiation of the sample, makes it possible to quickly and accurately analyze the elemental composition of a large number of samples (Franzini et al., 1972). The main advantage is considered to be non-destructive sample preparation, i.e. no stage of destruction of the material under study by chemical reagents or high temperature.”

Abstract: Plant organisms absorb heavy metals and pollutants from the atmosphere and are actively used in phytoremediation methods, being in fact a “filter” of ecosystems. Coniferous pine needles are one of the most frequently used objects of monitoring studies, which is due to a wide ecological amplitude and increased sensitivity to anthropogenic changes in the process of ontogenesis. The aim of the study is the ecological assessment of the content and peculiarities of accumulation of chemical elements in the conifers of the undergrowth of common pine (Pinus sylvestris)of different age classes. X-ray fluorescence analysis (Portable X-ray fluorescence analyzer SciAps X-Series X-200, USA) was used to determine the elemental composition of plant samples. The concentration of chemical elements belonging to different classes was determined: vital, conditionally necessary, toxic. The average content of elements is as follows: for 1 year old conifers:K > Ca > Fe > S > P > Mn > Ba > Ti > Zn > Sr > Cr> Cr > Rb > Cu > Ni > Mo > Pb > Zr > V > As > Y. By the conifer of subsequent years of life Ca > K > Fe > S > P >Ba > Mn > Ti > Sr > Sr > Zn > Cr > Cr > Rb > Ni >Cu > Mo > Pb > Zr > V > As > Y.
