Аннотация: Река Енисей загрязнена техногенными радионуклидами в результате производства оружейного плутония на Горно-химическом комбинате (ГХК) в г. Железногорске (Россия) в течение более 50 лет. Последнее реакторное производство на ГХК было остановлено в 2010 г. В данной работе представлены данные по накоплению техногенных радионуклидов промысловыми рыбами (щукой, Esox lucius; хариусом, Thymallus arcticus, и ельцом, Leuciscus leuciscus baicalensis), обитающими на радиоактивно загрязненном участке р.Енисей в 2005-2014 гг. Из числа техногенных радионуклидов, которые регистрировались в мышцах рыб во время работы последнего ядерного реактора (32P, 60Co, 65Zn, 137Cs), только 137Cs регистрировался в течение четырех лет после остановки реакторного производства на ГХК. Содержание 137Cs в мышцах рыб было значительно ниже установленных в Российской Федерации санитарных норм. Содержание 137Cs в мышцах хищных рыб было выше, чем в мышцах мирных. Содержание 137Cs в ихтиофауне р. Енисей не снизилось после остановки последнего реакторного производства на ГХК, в то время как содержание радионуклидов с наведенной активностью снизилось значительно. Это можно объяснить неизменным потоком 137Cs в р. Енисей со сбросами радиохимического производства ГХК и депозитами 137Cs в донных отложениях. Можно ожидать, что концентрация 137Cs в мышцах рыб не снизится в ближайшие десятилетия.
The Yenisei River is contaminated with artificial radionuclides due to the weapons-grade plutonium production at the Mining-and-Chemical Combine (MCC) at Zheleznogorsk (Russia) for more than 50 years. The last reactor plant at the MCC was shut down in 2010. The research presents the data on accumulation of artificial radionuclides in wild fish (pike, Esox lucius; grayling, Thymallus arcticus; and dace, Leuciscus leuciscus baicalensis) inhabiting the radioactively contaminated part of the Yenisei River between 2005 and 2014. Among artificial radionuclides that were detected in fish muscles when the last nuclear reactor plant was operating (32P, 60Co, 65Zn, 137Cs), only 137Cs was recorded four years after the shutdown of the nuclear power plant at the MCC. The concentrations of 137Cs in fish muscles were considerably below the sanitary norms for this radionuclide in the Russian Federation. Piscivorous fish species accumulated higher concentration of 137Cs in their muscles than non-predatory species. Concentration of 137Cs in fish fauna of the Yenisei River did not decrease after the shutdown of the last nuclear power plant at the MCC, while the concentration of radionuclides with induced activity decreased considerably. This can be explained by the constant inflow of 137Cs into the Yenisei River due to discharges from the radiochemical plant at the MCC and the deposits of 137Cs in the bottom sediments. We can expect that the concentration of 137Cs in fish muscles will not decrease in the next few decades.

Аннотация: An experimental model of matter turnover in the biotic cycle: plants (plant biomass) -- mushrooms (residual substrate + mushroom fruit bodies) -- worms (biohumus) -- microorganisms (soil-like substrate) -- plants is presented. The initial mass of soillike substrate was produced from wheat plants grown in a hydroponic system, Three cycles of matter turnover in the biotic cycle were carried out. Grain productivity on soillike substrate was 21.87 g/m(2) day(1). The results obtained were used for designing a CES containing man, plants, soillike substrate, bioregeneration module and aquaculture. It was shown, that the circulating dry mass of the CES is 756 kg. The main part (88%) of the circulating mass accumulates in the soillike substrate and bioregeneration module. (C) 1997 COSPAR.

Аннотация: The effect of elevated temperatures of 35 and 45В°C (at the intensities of photosynthetically active radiation 322, 690 and 1104 ?mol-m-2-s-1) on the photosynthesis, respiration, and qualitative and quantitative composition of the volatiles emitted by wheat (Triticum aestuvi L., cultivar 232) crops was investigated in growth chambers. Identification and quantification of more than 20 volatile compounds (terpenoids - ?-pinene, ?3 carene, limonene, benzene, ?-and transcaryophyllene, ?- and ?-terpinene, their derivatives, aromatic hydrocarbons, etc.) were conducted by gas chromatograph/mass spectrometry. Under light intensity of 1104 ?mol-m-2-s-1, heat resistance of photosynthesis and respiration increased at 35В°C and decreased at 45В°C. The action of elevated temperatures brought about variations in the rate and direction of the synthesis of volatile metabolites. The emission of volatile compounds was the greatest under a reduced irradiation of 322 ?mol-m-2-s-1 and the smallest under 1104 ?mol-m-2-s-1 at 35В°C. During the repair period, the contents and proportions of volatile compounds were different from their initial values, too. The degree of disruption and the following recovery of the functional state depended on the light intensity during the exposure to elevated temperatures. The investigation of the atmosphere of the growth chamber without plants has revaled the substances that were definitely technogenic in origin: tetramethylurea, dimethylsulfide, dibutylsulfide, dibutylphthalate, and a number of components of furan and silane nature.

Аннотация: The effects of elevated temperature (35 and 45В°C) on photosynthesis, respiration, and both the qualitative and quantitative compositions of volatile emissions (VE) of wheat (Triticum aestuvum L. cultivar 232) cenoses at light intensities of 70, 150, or 240 W/m2 of photosynthetically available radiation (PAR) were studied. At a PAR of 240 W/m2, the thermal stabilities of photosynthesis and respiration increased at 35В°C and decreased at 45В°C. Elevated temperatures nonuniformly changed the rates and direction of VE syntheses. In this process, the highest increase in VE evolution was observed at 70 W/m2 and 35В°C; the lowest, at 240 W/m2. In addition, the concentrations and composition of VE during the repair period differed from the initial values.

Use of human wastes oxidized to different degrees in cultivation of higher plants on the soil-like substrate intended for closed ecosystems / A. A. Tikhomirov [et al.] // Advances in Space Research. - 2010. - Vol. 46, Is. 6. - P744-750, DOI 10.1016/j.asr.2010.02.024 . - ISSN 0273-1177

Аннотация: To close mass exchange loops in bioregenerative life support systems more efficiently, researchers of the Institute of Biophysics SB RAS (Krasnoyarsk, Russia) have developed a procedure of wet combustion of human wastes and inedible parts of plants using H2O2 in alternating electromagnetic field. Human wastes pretreated in this way can be used as nutrient solutions to grow plants in the phototrophic unit of the LSS. The purpose of this study was to explore the possibilities of using human wastes oxidized to different degrees to grow plants cultivated on the soil-like substrate (SLS). The treated human wastes were analyzed to test their sterility. Then we investigated the effects produced by human wastes oxidized to different degrees on growth and development of wheat plants and on the composition of microflora in the SLS. The irrigation solution contained water, substances extracted from the substrate, and certain amounts of the mineralized human wastes. The experiments showed that the human wastes oxidized using reduced amounts of 30% H2O2: 1 ml/g of feces and 0.25 ml/ml of urine were still sterile. The experiments with wheat plants grown on the SLS and irrigated by the solution containing treated human wastes in the amount simulating 1/6 of the daily diet of a human showed that the degree of oxidation of human wastes did not significantly affect plant productivity. On the other hand, the composition of the microbiota of irrigation solutions was affected by the oxidation level of the added metabolites. In the solutions supplemented with partially oxidized metabolites yeast-like microscopic fungi were 20 times more abundant than in the solutions containing fully oxidized metabolites. Moreover, in the solutions containing incompletely oxidized human wastes the amounts of phytopathogenic bacteria and denitrifying microorganisms were larger. Thus, insufficiently oxidized sterile human wastes added to the irrigation solutions significantly affect the composition of the microbiological component of these solutions, which can ultimately unbalance the system as a whole.

Аннотация: The purpose of this work was to develop technology for recycling NaCl containing in human liquid waste as intrasystem matter in a bioregenerative life support system (BLSS). The circulation of Na+ and Cl- excreted in urine is achieved by inclusion of halophytes, i.e. plants that naturally inhabit salt-rich soils and accumulate NaCl in their organs. A model of Na+ and Cl- recycling in a BLSS was designed, based on the NaCl turnover in the human-urine-nutrient solution-halophytic plant-human cycle. The study consisted of (i) selecting a halophyte suitable for inclusion in a BLSS, and (ii) determining growth conditions supporting maximal Na + and Cl- accumulation in the shoots of the halophyte growing in a nutrient solution simulating mineralized urine. For the selected halophytic plant, Salicornia europaea, growth rate under optimal conditions, biomass production and quantities of Na+ and Cl- absorbed were determined. Characteristics of a plant production conveyor consisting of S. europaea at various ages, and allowing continuity of Na+ and Cl - turnover, were estimated. It was shown that closure of the NaCl cycle in a BLSS can be attained if the daily ration of fresh Salicornia biomass for a BLSS inhabitant is approximately 360 g. В© 2010 COSPAR.

Аннотация: Since introduction of neural networks into remote sensing they demonstrate good efficiency in remote sensing data analysis. This work is devoted to processing of multispectral (12 bands) images from Sentinel-2(A, B) satellites. Satellite images of areas in Krasnoyarsk Region and Khakassia with known vegetation types are used as task books to train neural networks. Trained neural networks have been reduced to determine which bands are significant for vegetation type identification. Reduction of trained neural network show that vegetation type can be determined from only four infrared bands without significant loses in performance in comparison with non-reduced neural network. © Published under licence by IOP Publishing Ltd.

Аннотация: The localization of the key photoreductive and oxidative processes and some stress-protective reactions within leaves of mesophytic C3 plants were investigated. The role of light in determining the profile of Rubisco, glutamate oxaloacetate transaminase, catalase, fumarase, and cytochrome-c-oxidase across spinach leaves was examined by exposing leaves to illumination on either the adaxial or abaxial leaf surfaces. Oxygen evolution in fresh paradermal leaf sections and CO2 gas exchange in whole leaves under adaxial or abaxial illumination was also examined. The results showed that the palisade mesophyll is responsible for the midday depression of photosynthesis in spinach leaves. The photosynthetic apparatus was more sensitive to the light environment than the respiratory apparatus. Additionally, examination of the paradermal leaf sections by optical microscopy allowed us to describe two new types of parenchyma in spinach-pirum mesophyll and pillow spongy mesophyll. A hypothesis that oxaloacetate may protect the upper leaf tissue from the destructive influence of active oxygen is presented. The application of mathematical modeling shows that the pattern of enzymatic distribution across leaves abides by the principle of maximal ecological utility. Light regulation of carbon metabolism across leaves is discussed. В© 2010 Springer-Verlag.

Аннотация: The long-term operation of three reactors and the radiochemical plant of the Mining-and-Chemical Combine (MCC), Russia's largest producer of weapons-grade plutonium, has resulted in radioactive contamination of the Yenisei River floodplain. From 1995 to 2016, we found more than 200 radioactive particles (RP) in the Yenisei floodplain, downstream of the MCC. Analytical characterization showed that most of the RP were fuel particles, which were carried into the river after incidents at the MCC reactors. Having compared the Cs-137/Cs-134 ratios in the particles, we determined three time intervals when the RP were formed. The plutonium isotope ratios (Pu-238/Pu-239,Pu-240) vary substantially between the particles and indicate several different source terms. In addition to fuel RP, we found particles that only contained activation products (Co-60 or europium isotopes). SEM and gamma-spectrometry showed that the cobalt particles could have originated from the corrosion of the reactor coolant system and the europium particles -from the damaged compensating rods. No europium particles have been found anywhere else in the world. The presence of RP from different sources (fuel, cobalt, and europium particles) in the Yenisei River floodplain makes this region a unique site for studying environmental effects of the particles. These RP represent point sources of radioecological significance.

Аннотация: The feasibility of a two-stage bioconversion of inedible potato biomass into biohumus by oyster mushroom followed by worms was tested. As a raw material for biohumus production the inedible potato biomass in certain properties ranked below wheat straw. The most feasible method to convert the potato wastes into biohumus was to mix them with wheat straw at the mass ratio of 1:3 and then treat with mushrooms followed by worms. This gave a good yield of mushrooms. The biohumus produced from the mixture was suitable for use as a plant growth medium. (C) 2001 Elsevier Science Ltd. All rights reserved.

Tritium in surface waters of the Yenisei River basin / A. Y. Bolsunovsky, L. G. Bondareva // Journal of Environmental Radioactivity. - 2003. - Vol. 66, Is. 3. - P285-294, DOI 10.1016/S0265-931X(02)00132-7 . - ISSN 0265-931X

Аннотация: This paper reports an investigation of the tritium content in the surface waters of the Yenisei River basin near the Mining and Chemical Combine (MCC). In 2001 the maximum tritium concentration in the Yenisei River did not exceed 4 В± 1 Bq l-1, which is consistent with the data of 1998-99. However, it has been found that there are surface waters containing enhanced tritium as compared with the background values for the Yenisei River. For instance, in the Ploskii Stream and the Shumikha River the maximum tritium concentrations amount to 168 and 81 Bq l-1, respectively. The source of tritium in these surface waters is the last operating reactor at the MCC, which still uses the Yenisei water as coolant. In water and sediment samples of the Bolshaya Tel River (a tributary of the Yenisei River) the tritium content turned out to be at least 10 times higher than the background values for the Yenisei River. The measurements conducted at the RPA RADON (Moscow) revealed not only tritium but also the artificial radionuclide 14C in the Bolshaya Tel samples. The data obtained suggest that the Bolshaya Tel River receives the major part of tritium from sediments rather than from the water catchment area. This allows the conclusion that there is water exchange between the surface waters and the radioactively contaminated underground horizons of the "Severny" testing site. В© 2002 Elsevier Science Ltd.

Trace elements exchange in experimental closed life support systems [Text] / I. V. Gribovskaya, V. Y. Rygalov ; ed. ya, IV Gribovs // SIXTH EUROPEAN SYMPOSIUM ON SPACE ENVIRONMENTAL CONTROL SYSTEMS, VOLS 1 AND 2. Ser.

Аннотация: Measurements of trace elements incoming and exiting ''Bios-3'' biological-engineering life support system evidence presence of a source of these elements inside the system. This source is, most probably, structural units (steel walls, hose rubber, plastic coatings), catalysts of the thermal catalytic incinerator, expanded clay aggregate mechanically fixing plants and so on. The trace elements are received by the nutrient solutions and build up in the plant biomass. As a consequence the crew may receive elevated doses of such trace elements as aluminum, lead, nickel, chromium. To reduce income of trace elements to LSS requires thorough selection and preliminary treatment of structural materials with reduced desorption capacities and running-in of the system in idle mode prior to exploitation. This mode involves operation of the engineering part of the system (without plants and humans, but with nutrient solutions) for several months.

Toxic effects of the fungicide tebuconazole on the root system of fusarium-infected wheat plants / E. Shishatskaya [et al.] // Plant Physiol. Biochem. - 2018. - Vol. 132. - P400-407, DOI 10.1016/j.plaphy.2018.09.025 . - ISSN 0981-9428

Аннотация: The study investigates toxic effects of the fungicide tebuconazole (TEB) on Fusarium-infected wheat (Triticum aestivum) plants based on the morphological characteristics of root apices and changes in the integrated parameters of redox homeostasis, including the contents of free proline and products of peroxidation of proteins (carbonylated proteins, CP) and lipids (malondialdehyde, MDA) in roots. In two-day-old wheat sprouts infected by Fusarium graminearum, the levels of proline, CP, and border cells of root apices are higher than in roots of uninfected sprouts by a factor of 1.4, 8.0, and 3, respectively. The triazole fungicide tebuconazole (TEB) at the concentrations of 0.01, 0.10, and 1.00 ?g ml?1 of medium causes a dose-dependent decrease in the number of border cells. The study of the effects of TEB and fusarium infection on wheat plants in a 30-day experiment shows that the effect of the fungicide TEB on redox homeostasis in wheat roots varies depending on the plant growth stage and is significantly different in ecosystems with soil and plants infected by Fusarium phytopathogens. The study of the morphology of root apices shows that the toxic effects of TEB and fusarium infection are manifested in the destructive changes in root apices and the degradation of the root tip mantle. © 2018 Elsevier Masson SAS

Аннотация: The main objective of a life support system for space missions is to supply a crew with food, water and oxygen, and to eliminate their wastes. The ultimate goal is to achieve the highest degree of closure of the system using controlled processes offering a high level of reliability and flexibility. Enhancement of closure of a biological life support system (BLSS) that includes plants relies on increased regeneration of plant waste, and utilization of solid and liquid human wastes. Clearly, the robustness of a BLSS subjected to stress will be substantially determined by the robustness of the plant components of the phototrophic unit. The aim of the present work was to estimate the heat resistance of two plants (wheat and lettuce) grown on human wastes. Human exometabolites mineralized by hydrogen peroxide in an electromagnetic field were used to make a nutrient solution for the plants. We looked for a possible increase in the heat tolerance of the wheat plants using changes in photosynthetically active radiation (PAR) intensity during heat stress. At age 15 days, plants were subjected to a rise in air temperature (from 23 В± 1 В°C to 44 В± 1 В°) under different PAR intensities for 4 h. The status of the photosynthetic apparatus of the plants was assessed by external 2 gas exchange and fluorescence measurements. The increased irradiance of the plants during the high temperature period demonstrated its protective action for both the photosynthetic apparatus of the leaves and subsequent plant growth and development. The productivity of the plants subjected to temperature changes at 250 W m-2 of PAR did not differ from that of controls, whereas the productivity of the plants subjected to the same heat stress but in darkness was halved.

The heat resistance of the reproductive organs of 25-day-old plants was significantly lower than that of 15-day-old plants subjected to similar light and temperature conditions.

Аннотация: Stability of LSS based on biological regeneration of water, air and food subject to damaging factors is largely dependent on the behavior of the photosynthesizing component represented, mainly, by higher plants. The purpose of this study is to evaluate the tolerance of uneven-aged wheat and radish cenoses to temperature effects different in time and value. Estimation of thermal tolerance of plants demonstrated that exposure for 20 h to the temperature increasing to 45degreesC brought about irreversible damage both in photosynthetic processes (up to 80% of initial value) and the processes of growth and development. Kinetics of visible photosynthesis during exposure to elevated temperatures can be used to evaluate critical exposure time within the range of which the damage of metabolic processes is reversible. With varying light intensity and air temperature it is possible to find a time period admissible for the plants to stay under adverse conditions without considerable damage of metabolic processes.
