The variation limits and organ distribution of macroand trace elements were determined in plants of the three subspecies of Lonicera caerulea L. The leaves, as compared with the stems, were found to accumulate more of B, Са, Mg, Mo, P and Sr and less of Al, Mn, Ti and Zn. The plants of different subspecies, grown on soils of the similar chemical element composition, showed statistically significant differences in contents and organ distribution patterns of Al, Cr, Cu, Fe, Mg, Mo, Na, Ni, Pb, Si, Ti and Zn. The stems of the subspecies of the Far East provenance (L. сaerulea subsp. kamtschatica and L. сaerulea subsp. venulosa) had abnormally high contents of Al, Cr, Fe, Na, Si and Ti.

AbstractMore than 19,000 analytical data mainly from the literature were used to study statistically the distribution patterns of F and the oxides of minor and trace elements (Ti, Sn, Sc, V, Cr, Ga, Mn, Co, Ni, Zn, Sr, Ba, Rb, Cs) in trioctahedral micas of the system phlogopite-annite/siderophyllite-polylithionite (PASP), which is divided here into seven varieties, whose compositional ranges are defined by the parametermgli(= octahedral Mg minus Li). Plots of trace-element contentsvs.mglireveal that the elements form distinct groups according to the configuration of their distribution patterns. Substitution of most of these elements was established as a function ofmgli. Micas incorporate the elements in different abundances of up to four orders of magnitude between the concentration highs and lows in micas of ‘normal’ composition. Only Zn, Sr and Sc are poorly correlated tomgli. In compositional extremes, some elements (Zn, Mn, Ba, Sr, Cs, Rb) may be enriched by up to 2–3 orders of magnitude relative to their mean abundance in the respective mica variety. Mica/melt partition coefficients calculated for Variscan granites of the German Erzgebirge demonstrate that trace-element partitioning is strongly dependent on the position of the mica in the PASP system, which has to be considered in petrogenetic modelling.This review indicates that for a number of trace elements, the concentration ranges are poorly known for some of the mica varieties, as they are for particular host rocks (i.e. igneous rocks of A-type affiliation). The study should help to develop optimal analytical strategies and to provide a tool to distinguish between micas of ‘normal’ and ‘abnormal’ trace-element composition.

To study mineral composition of honeyberry (Lonicera caerulea L.) phytomass in contrasting geochemical environments, the accumulation of macro- and trace elements, as related to their soil content in undisturbed Mountainous Altai ecosystems,  was determined in organs of the Altai subspecies of honeyberry, growing in the geochemically anomalous environment on ultrabasic rocks and in the geochemically normal environment. Total chemical element content in soil and plants was determined by atomic emission spectrometry, while labile forms of  К, Na, Ca, Mg, Fe, Mn, Zn, Cu, Ni, Li, Sr were measured by atomic adsorption spectrometry. Organ distribution and variation limits were determined for 30 macro- and trace elements. Leaves were shown to accumulate Sr, Ni, Mo, B, Ga, La and Zr more intensively in comparison with stems, while the latter accumulated more intensively Al, Cu, Mn and Zn. Plants grown on ultrabasic rocks had decreased Ca, K, Fe and Sr contents and increased Mg and Ni contents as compared with plants growing  on acidic, carbonated and basic rocks. Decreased rate of K, Ca and Sr uptake by honeysuckle plants was most likely due to the mineral exchange distortion because of soil Ca/Mg ratio, which was unfavourable for plants. Leaves of plants growing on the ultrabasic rocks were shown to accumulate Ni in high concentrations. Increased Fe accumulation was found in leaves of plants growing on basic rocks, while stems had increased Fe concentrations in all study sites. The obtained results should be carefully considered for the purposed of phytomass collection and preparation for medicinal use.

Analysis of the historical faunistic explorations in Russia demonstrates the gradual improvement of knowledge during the 20th century for this country with variable borders. Recent estimations of the Trichoptera biodiversity in the Russian Federation show the presence of 643 species in 148 genera of 28 families within its limits. The largest family, Limnephilidae, comprises 159 species, followed by Leptoceridae (92 spp.), Hydroptilidae (56), Rhyacophilidae (49), Apataniidae (41), Polycentropodidae (35), Hydropsychidae (33), Phryganeidae (28), Glossosomatidae (23), Psychomyiidae (22), Philopotamidae (19), Lepidostomatidae (18), Goeridae (12), Brachycentridae (9), Molannidae (8), Beraeidae (6), Sericostomatidae (5), Stenopsychidae (5), Arctopsychidae (4), Ptilocolepidae (4), Ecnomidae (3), Uenoidae (3), Calamoceratidae (3), and Odontoceridae (2), with Hydrobiosidae, Dipseudopsidae, Phryganopsychidae, and Thremmatidae each with a single species. The fauna of Far East Russia is the richest with 392 species, whereas European Russia in inhabited by 225 spp., the Caucasus 155, and Siberia 239. Species distribution patterns are not known in detail even in European Russia. New additions to the fauna are expected from the Far East and other regions.

Purpose. The collection of the Museum of history and culture of peoples of Siberia and Far East at the Institute of Archaeology and Ethnography SB RAS has a unique section of ritual objects produced by the Ob Ugrians during Middle Ages. The collection features unique objects made of silver, which allows us to make a conclusion that silver had a sacral meaning for the Khanty and Mansi, and the material itself was closely connected with a complex of cosmological and mythological conceptions. Results. We conducted XRF analysis for a series of silver objects of cult and identified three objects made with the use of a special laborious technology by means of cold hammering from three sheets of silver. Conclusion. The article gives a full description of the objects and describes the semantics of the images presented. We provide the results of element composition of the metal and identify a circle of analogues. The artifacts considered included a metal plate with a solar sign made with gilding, with an engraving around it on the surface of metalwork, a stylized profile of attenuated heads of elks facing each other (the drawing was created later); the second item being a metal plate with a central part in the form of a medallion depicting a horseman who strikes a man lying at the horse’s legs with a spear (it was made by means of engraving on a ready form); and the third item being a platter with the images of an eagle owl standing on the back of a deer and a duck flying up. The plots of the silver items evidently have a cult significance and correspond to some mythological constructs. The unique technology of their three-layer composition is accounted for by mythological conceptions and enhances a sacral significance of the items.

Hypericum perforatum L. (St. John’s wort) is a popular medicinal plant, but its chemical element composition has been studied insufficiently, especially of the plants originated in the Russian Federation. The aim of the study was to examine chemical element composition of Hypericum perforatum L plants originating from the south of West Siberia and to review similar data on plants grown in other climatic zones and regions, attempting to establish chemical elements' ranges in the phytomass of the studied species. Chemical element concentrations were determined by AES in 100 samples of aboveground and 60 samples of belowground H. perforatum plant parts collected in West Siberia (Novosibirsk and Kemerovo regions, the Altai Republic). Total concentrations of various chemical elements did not differ (P≤0.05) in different samples. The aboveground plant parts were found to have very  high concentrations of K, Са, P, Si, Mg (n×103–104 mg/kg) alongside with high concentrations of Al, Fe, Na (n×102 mg/kg) and moderate concentrations of Мn, Sr, Ba, Zn, B, Ti, Cu (n×10 mg/kg), whereas such elements as Ni, Zr (n mg/kg) were found in decreased concentrations, while V, Cr, Mo, Co, Y, Ga showed low concentrations (n×10-1 mg/kg), Sc, Ве, Yb (n×10-2 mg/kg) being very low. The accumulation of Ba and Sr in plants revealed some regional peculiarities as their concentrations in plants of Siberian origin was higher than in plants of the European one. The average chemical element concentrations for a wide set of world data displayed a wider range, with extremely high or low values, as compared to the regional range of variation. The studied plants had no barriers for the uptake of Zn, Р, B, Mg, Mn and K, but for Са, Ва, Sr, Mo, Co in different samples the root barrier coefficient was higher, lower or equal to 1.

Beryllium is a chemical element composition of the Group 2 of the Periodic Table of Chemical Elements. It does not crystallize as a natural solid and exhibits a crustal abundance of 2.8 ppm. It is a chemical element among the trace elements with low representativity, together with erbinm and bromine. It shows a big chemical reactivity, and a low abundance in the chemical composition of minerals (only 96 minerals have beryllium in their chemical compositions). The principal beryllium-bearing minerals for industrial usages are beryl and bertrandite, and secondary sources are helvite, chrysoberyl, euclase, beryllonite, and phenakite. This review presents a synopsis of the beryllium-bearing minerals as a contribution to the scientific knowledge of these substances.
