Аннотация: In this work we experimentally estimated the capacities of the key components of the Yenisei River (Russia): particulate suspended matter (seston), diatom microalgae, and submerged macrophytes for accumulating Am-241 from water. In our experiments large particles of seston (>8 mu m), comparable in size with diatoms, took up most of americium from water. The accumulation of americium by isolated diatom algae (Asterionella formosa and Diatoma vulgare) was lower than by total seston. The concentration factors (CFs) of Am-241 for seston of the Yenisei River in our experiments were (2.8-6.9).10(5); for diatoms -(1.5-4.2)-10(4). The Us for aquatic plant Elodea canadensis were within the same order of magnitude as those for diatoms. Activity concentration and CFs of Am-241 were nearly the same in experiments under dark and light conditions. This is indicative of an energy independent mechanism of americium uptake from the water by diatoms and submerged macrophytes. (C) 2009 Elsevier Ltd. All rights reserved.

Аннотация: A mass-flow model of carbon cycle in a bioregenerative life support system (BLSS) including Resource, Plant Growth, Food Processing, Human, Waste Processing, and Waste Storage Modules was developed. A human received food from Plant Growth and Resource Modules. Plants were assumed to be growing on the soil-like substrate (SLS). Another function of SLS was balancing the carbon cycle. The input of BLSS was set to 81 g of carbon per day along with food from the Resource Module. To balance the carbon cycle an equal arnount of carbon was removed from BLSS along with urine, feces, plant wastes, and SLS. A mass flow of carbon cycle was used to simulate the effect of light intensity on the basic parameters of the Plant Growth Module. It was calculated that the stationary dry mass of SLS increases from 10 to 35 kg m(-2) with increase canopy-level daily photosynthetic photon flux (PPF) from 34 to 178 mol m(-2) d(-1). On the contrary dry mass of SLS needed to provide one person with plant food is not dependent on light intensity. (C) 2008 Elsevier Ltd. All rights reserved.

Antibiotic resistance of heterotrophic bacteria in Shira lake: natural and anthropogenic impacts [Text] / T. I. Lobova, Y. V. Barkhatov, L. Y. Popova // Aquat. Microb. Ecol. - 2002. - Vol. 30, Is. 1. - P. 11-18, DOI 10.3354/ame030011. - Cited References: 33 . - ISSN 0948-3055

Аннотация: Studies were conducted to investigate the antibiotic resistance of freshwater, halophile and moderate halotolerant bacteria isolated from the nearshore part of Shira lake, which is affected by the activity of a health resort, and from the central part of the lake in the summer (June to August) of 1999. It has been shown that the allochthonous microflora, which is brought into the lake with the resort effluent in mid-summer, is the anthropogenic factor contributing to an increase in the number of freshwater bacteria that feature multiple antibiotic resistance in the central part of the lake. It has been found that resistance to ampicillin of freshwater and halophile heterotrophic bacteria is related to the increase in the biomass of blue-green and green algae in the central part of Shira lake between mid-July and the end of August. A mathematical model has been constructed to describe the dynamics of the antibiotic resistance of heterotrophic bacteria in the close-to-resort and the central parts of Shira lake under natural and anthropogenic impacts.

Аннотация: In order to establish material loops in biotechnical life support systems (BTLSS), various types of organic waste generated within the system need to be effectively processed. A universal method should be developed to produce mineral fertilizers for the higher-plant compartment of the BTLSS regardless of the level of reduction of the organic compounds contained in the waste and the contents of mineral elements in it. A method of producing mineral fertilizers by organic waste oxidation in the hydrogen peroxide aqueous solution under application of an alternating current electric field is proposed as a possible approach Methods of processing of human wastes and inedible plant biomass were discussed in previous studies. The present study demonstrates the approach to processing cotton waste and kitchen wastewater. The study describes processing of such wastes by using a supplementary oxidizer (nitric acid) and co-oxidation with other types of organic waste typically generated in the BTLSS. Recommendations are offered on using these approaches to process sanitary/household waste in the BTLSS.

Аннотация: Long-term trends of artificial radionuclides, from 2003 to 2018, in two abundant species of macrophytes, shining pondweed, Potamogeton lucens, and water moss, Fontinalis antipyretica, have been analyzed to estimate the indicative reliability of these two species as biomonitors of radioactive contamination in a river system and to quantify the decrease in the content of artificial radionuclides in the Yenisei River. Time-dependent trends of artificial radionuclides in the biomass of these species were similar, resulting in estimates of effective half-lives for Mn-54, Co-58, Co-60, Zn-65, Cs-137, and Eu-152 similar for both species. Concentrations of artificial radionuclides in biomass of shining pondweed and water moss correlated with annual discharges of the radionuclides to the Yenisei at different levels of significance, and the strongest (R-2 > 0.7) positive correlation (p < 0.05) was obtained for Co-60, Zn-65, and Eu-152. Concentrations of Co-60, Cs-137, and Eu-152 in water moss were 2-7.5 times higher than in shining pondweed, and considerable percentages of those isotopes were recorded in extracellular particulate matter, which was largely represented by epiphytic diatoms. Higher concentrations of artificial radionuclides in the biomass of water moss can be considered as an advantage of water moss as a monitor of radioactive contamination of the Yenisei, while shining pondweed is more useful for estimation of annual deposits of radionuclides in vegetation of the Yenisei and spatial transfer of radionuclides downstream of the discharge site. Despite differences in concentrations of artificial radionuclides, both species can be considered as reliable indicators of radioactive contamination of the river on a long-term scale.
