Аннотация: In order to constrain the origin and fluxes of elements carried by rivers of high latitude permafrost-dominated areas, major and trace element concentrations as well as Sr and U isotopic ratios were analyzed in the dissolved load of two Siberian rivers (Kochechum and Nizhnyaya Tunguska) regularly sampled over two hydrological cycles (2005-2007). Large water volumes of both rivers were also collected in spring 2008 in order to perform size separation through dialysis experiments. This study was completed by spatial sampling of the Kochechum watershed carried out during summer and by a detailed analysis of the main hydrological compartments of a small watershed. From element concentration variations along the hydrological cycle, different periods can be marked out, matching hydrological periods. During winter baseflow period (October to May) there is a concentration increase for major soluble cations and anions by an order of magnitude. The spring flood period (end of May-beginning of June) is marked by a sharp concentration decrease for soluble elements whereas dissolved organic carbon and insoluble element concentrations strongly increase. When the spring flood discharge occurs, the significant increase of aluminum and iron concentrations is related to the presence of organo-mineral colloids that mobilize insoluble elements. The study of colloidal REE reveals the occurrence of two colloid sources successively involved over time: spring colloids mainly originate from the uppermost organic-rich part of soils whereas summer colloids rather come from the deep mineral horizons. Furthermore, U and Sr isotopic ratios together with soluble cation budgets in the Kochechum river impose for soluble elements the existence of three distinct fluxes over the year: (a) at the spring flood a surface flux coming from the leaching of shallow organic soil levels and containing a significant colloidal component (b) a subsurface flux predominant during summer and fall mainly controlled by water-rock interactions within mineral soils and (c) a deep groundwater flux predominant during winter which enters large rivers through unfrozen permafrost-paths. Detailed study of the Kochechum watershed suggests that the contribution of this deep flux strongly depends on the depth and continuous nature of the permafrost. (C) 2011 Elsevier Ltd.

Аннотация: Aluminum, Sc, Th, Hf, and lanthanoids belong to groups of elements that are, slightly, very slightly, and moderately captured in marsh ecosystems. In the genesis of the peatbog the biogeochemical migration of elements is mainly determined by the quality of the humus barriers as well as by the capability to form intermetallic compounds of widely varying compositions. In the surface layer (10 cm) of the peatbog the highest content of Al, Hf, Ce, and Sm over the entire history of marsh development was observed. This fact reflects the modem tendency to forming technogenic streams of the above content.

Аннотация: This paper studies how aluminum smelter emissions into the atmosphere affect the accumulation of fluorine by soil and plants, as well as change the chemical composition in leaves of woody plants. The ratio between total and extractable fluorine is ascertained to vary widely depending on the plant species. Meanwhile, gas resistant plants are characterized by an increased ash content in leaves (at the expense of K, P, Ca, etc.) and growth in the ratio between total and water-soluble fluorine. Plant resistance to fluorine that enters tissues depends on the capability of an organism to transform the toxicant into insoluble forms, which are not involved in physiological processes, i.e., on the presence of tissue elements with high precipitating capability. The gas-resistant species are ascertained to be characterized by high capability of limiting the intake of fluorine through roots, as well as its migration through a plant (especially to the organs that determine the further development of an organism). © 2014 Pleiades Publishing, Ltd.

Аннотация: In a Siberian river, the concentrations of chemical species vary with the hydrological regime. Dissolved Organic Matter (DOM) and aluminum ions show a parallel trend in the course of the hydrological year. However, the speciation of aluminum in this natural environment remains an open question. We propose here a combination of spectroscopic techniques to investigate the proximity between the aluminum atoms and DOM. First, one-dimensional (1D) solid-state Nuclear Magnetic Resonance (NMR), Electron Paramagnetic Resonance (EPR) and 1D and 2D solution NMR spectra were acquired, providing a clear overview of the DOM composition. Second, the sensitivity enhancement yielded by Dynamic Nuclear Polarization enabled the NMR detection of proximities between the Al-27 and C-13 nuclei. Hence, we show that 8.3 +/- 1.3% of the carboxylate groups observed by NMR are connected to the Al3+ ions in the DOM sample. We here demonstrate for the first time how advanced solid-state NMR methods can provide key information about the localization of aluminum in such complex natural materials. (C) 2017 Elsevier B.V.

Аннотация: The vulnerability of soil organic matter (SOM) sequestered in permafrost-affected soils to climate change plays one of the key roles in the global carbon (C) cycle. However, it still remains unclear how changing soil and site-specific factors, associated with the changing depth of the permafrost table due to thawing, influence the spatial distribution and variability of soil organic carbon (SOC) and total nitrogen (N) stocks in high-latitude mineral soils. The relationships between the spatial variation of SOC and N stocks (0–30 cm) and active layer (AL) thickness, thickness of the organic layer (OL), soil acidity, Al and Fe hydroxides as well as plant- and microbial-derived C inputs were studied using ordinary statistics and geostatistics within six landscape patches (16 m2) in the Siberian forest-tundra ecotone underlain by warm and discontinuous permafrost. At deeper permafrost table, SOC and N stocks (0–30 cm) were lower and, according to the semivariogram analysis, an overall homogenization of SOC and N distribution at the analyzed scale occurred. Total N and SOC stocks were spatially independent from root-derived organic matter distribution (i.e. the concentration of suberin-derived monomers) at shallow AL patches, whereas there was a significant positive spatial correlation within deep AL and non-permafrost soils. Hence, the development of root systems and an increase in rooting depth, leading to “hot spots” of SOM accumulation at intensively rooted soil patches, was observed as a result of deeper AL. Total N and SOC stocks within deeper AL and non-permafrost subsoils were also positively spatially correlated with the concentration of Fe and Al hydroxides, demonstrating the importance of organo-mineral associations for SOM stabilization in soils with lower permafrost table. This study confirmed that deepening of the AL in boreal forest ecosystems may lead to an overall homogenization of SOM distribution and simultaneous development of distinct mechanisms of SOM accumulation and stabilization. © 2018 Elsevier B.V.

Аннотация: The vegetation cover characteristics of anthropogenically disturbed birch stands of Krasnoyarsk forest-steppe are studied. The research purpose is to study the current state of under-story vegetation cover of the birch stands, which have been exposed to recreational and anthropogenic impacts for a long time, as well as to assess the degree and nature of its change over the 12-year period since the last research. The studies were carried out on the sample plots laid out in mixed herbs birch stands. Cenosises are characterized by V-VI age classes, II-IV quality classes, and 0.6-0.9 density of stocking. The birch stands are located in the main transfer of Krasnoyarsk industrial emissions. Phytocenoses were under significant anthropogenic and recreational impact for a long time. At each facility, 30 sites (1 m(2) each) were laid, where species composition, horizontal and vertical structure, projective cover and occurrence of undergrowth and forest live cover species were assessed. The comparative analysis of floristic lists was performed using the Sorensen-Czekanowski coefficient (K-sc). The degree of species diversity was estimated by using the Shannon index; the degree of recreational transformation - synanthropization index. Cuttings were taken from 10 sites (20 x 25 cm each) for recording the phytomass stock of forest live cover on each sample area. Plants were cut off at the litter level, sorted by species, dried and weighed. Rating scales of digression were used to study the recreation influence. The degree of anthropogenic impact was determined by the content of toxic ingredients in plants of living ground cover. It is found that the toxic elements concentration in plants does not reach excessive values at which homeostasis disturbance happens. It was concluded that the changes in vegetation cover observed in 2017 in relation to the state of 2005 are more due to recreational than anthropogenic impact; which changed due to the introduction of a new technology at the JSC "RUSAL Krasnoyarsk Aluminum Plant", which made it possible to reduce toxic industrial emissions. According to the study results, the species composition of the undergrowth and forest live cover was determined, the features of its change over a 12-year period were revealed. It is noted that species diversity has decreased and the proportion of synanthropic species has increased across all plots. Total forest live cover phytomass and individual species phytomass are determined at each plot. The regularities of change in different species contribution to the total stock of phytomass, depending on recreational impact changes, were identified. The ground cover recreational digression stages are determined by analyzing the changes in species diversity, the quantitative ratio of ecological-cenotic groups, the structure and the absolute value of phytomass.

Аннотация: Изучено содержание фотосинтетических пигментов в листьях березы повислой (Betula pendula Roth.) в условиях техногенных нагрузок и в фоновых условиях. Исследования проводили в березняках разнотравного типа леса в пригородной зоне г. Красноярска. Древостои, испытывающие техногенные нагрузки, расположены к востоку от города по направлению основного переноса воздушных масс, фоновые - в северном и западном направлениях от города, техногенная нагрузка на эти древостои минимальна. Содержание фотосинтетических пигментов определяли в этанольных экстрактах, расчет проводили на 1 г абсолютно сухой массы листьев. Аккумуляцию пыли листовой поверхностью оценивали по методике Ж. Детри (1973). В промытых листьях определяли содержание ионов цинка, свинца, алюминия и фтора. Показано, что содержание хлорофилла а в листьях берез из условно чистых мест произрастания несколько ниже, чем в листьях из древостоев, подвергающихся техногенным нагрузкам. Содержание хлорофилла b в листьях берез из разных мест произрастания оказалось в 2,5-3 раза ниже, чем хлорофилла а, и сопоставимо с содержанием каротиноидов. Общее содержание хлорофиллов колебалось от 5,4 до 7,3 мг/г абсолютно сухой массы, соотношение форм хлорофиллов - от 2,5 до 3, отношение суммы содержания хлорофиллов к суммарному содержанию каротиноидов - от 3,4 до 3,8. При увеличении пылевой нагрузки росло содержание всех фотосинтетических пигментов. Накопление ионов цинка в клетках листа березы отрицательно сказывалось на содержании пигментов, особенно хлорофилла а, но с соотношением пигментов не коррелировало. Значимой корреляции содержания свинца и фотосинтетических пигментов не установлено. При увеличении концентрации алюминия в листьях количество хлорофиллов и каротиноидов достоверно возрастало, связи уровня алюминия с соотношением пигментов не обнаружено. Между содержанием фтора в листовой массе и количеством разных форм хлорофилла достоверных корреляций не найдено. Полученные результаты свидетельствуют об адаптивной реакции фотосинтетического аппарата на присутствие поллютантов в концентрациях ниже пороговых значений
The content of photosynthetic pigments in silver birch leaves (Betula pendula Roth.) is studied in areas with technogenic load and in baseline conditions. The research is performed in a forb type of birch forest in the suburbs of Krasnoyarsk. The wood stands exposed to a high level of technogenic pressure are located to the east of the city in the prevailing direction of air mass movement. The reference stands are under the least technogenic pollution and grow in western and northern areas of the city. The photosynthetic pigments are determined in ethanol extracts, calculated per 1 g of absolute dry mass (a.d.m.) of the leaves. A level of dust deposition on leaf surfaces is evaluated according to the method of J. Detrie (1973). The amounts of zinc, lead, aluminum, and fluorine ions are estimated in the washed leaves. It is found that the content of chlorophyll a inside the birch leaves from a relatively clean environment is slightly lower compared to the concentration in the leaves with the technogenic load. The chlorophyll b concentration is 2.5-3 times less than chlorophyll a and is close to the amount of carotenoids. The total chlorophyll content in birch leaves from different locations ranges from 5.4 to 7.3 mg/g a.d.m., the ratio of chlorophyll forms varies from 2.5 to 3, the proportion of net chlorophyll to carotenoids is between 3.4 and 3.8. As the level of dust increases, the content of the total photosynthetic pigments also rises. The accumulation of zinc ions in the birch leaf cells has a negative effect on pigment content, especially chlorophyll a, but doesn’t correlate with the ratio of the pigments. There has not been any correlation found between the lead and the photosynthetic pigments. It is noted that the rise in the concentration of aluminum significantly affects the contents of the chlorophylls and the carotenoids, while no relationship has been discovered between the concentration of aluminum and the proportion of the pigments. The relationship between fluorine and different forms of chlorophyll is absent as well. The results indicate the adaptive response of the photosynthetic system to the presence of pollutants in concentrations below the threshold values that are indicated in the literature

Аннотация: Береза повислая (Betula pendula Roth.) характеризуется как устойчивый к техногенному загрязнению среды вид древесных растений. Известно, что генеративные процессы растений и, в частности, формирование и жизнеспособность пыльцы крайне чувствительны к воздействию техногенного загрязнения. Исследования жизнеспособности пыльцы проводились в условиях Средней Сибири, в наиболее распространенной группе типов леса - березняках разнотравных, произрастающих в пригородной зоне крупного промышленного центра г. Красноярска, на восьми пробных площадях. Несмотря на устойчивость вида, мужские генеративные органы B. pendula оказались чувствительными к воздействию промышленного загрязнения. Исследования показали снижение качества пыльцы при усилении степени техногенной нагрузки, достоверных различий по диаметру пыльцевых зерен в различных условиях произрастания, как и деформированных пыльцевых зерен не обнаружено. Уровень изменчивости размеров пыльцевых зерен по диаметру в биоценозе не превышал 9,3-9,9 %. Максимальное число проросших пыльцевых зерен отмечалось в фоновых условиях, минимальное - на восточной окраине города, по основному направлению переноса техногенных аэрозолей. Длина пыльцевых трубок у деревьев, растущих в этих условиях, уменьшалась более чем в 2 раза по отношению к критическому значению (диаметр пыльцевого зерна 18-20 мкм). Выявлены взаимосвязи прорастания пыльцы и количества пыли, аккумулированной на листовых пластинках, а также содержания в ассимиляционной массе свинца и алюминия ( r = - 0,1-0,3; р ≤ 0,05). Функциональные показатели пыльцы березы повислой можно рекомендовать в качестве биоиндикационного показателя при проведении мониторинга окружающей среды.
Betula pendula Roth. is tolerant to tehchnogenic air pollutants. However, the viability of pollen decreases under stress conditions, as well as under air pollution. The researches were conducted in Middle Siberia on eight plots of motley birches near industrial city of Krasnoyarsk. In each plot on west side of 15-20 trees, male twigs were cut at pollination time. Pollen was extracted from the male generative organs for size and viability (potential, by starch test, and realized, by in vitro germination) determination. The results were analyzed by statistical methods. The researches have revealed reduction of pollen viability under technogenic pollution and reliable differences in pollen grain diameters under different growing conditions, whereas deformed pollen grain were not revealed. The variability of pollen grains in diameter in the biocenosis did not exceed 9.3-9.9 %. Maximum number of sprouted pollen grains observed under background conditions, and minimum at the eastern border of city in the main direction of the transfer of technogenic aerosols. The length of pollen tubes in trees growing under these conditions decreased by more than twice in comparison to the critical value (namely, pollen grain diameter of 18-20 µm). Regression analysis has shown correlations between pollen germination and accumulation of dust on foliage, as well as of lead and aluminum content in the foliage ( r = - 0.1-0.3, р ≥ 0.05)). In spite of tolerance of the species to air pollution, Betula pendula male generative structures are sensitive to the contamination. Pollen viability can be used as a bioindicator of environmental pollution at monitoring.
