Аннотация: The efficiency of the transfer of gamma-emitting radionuclides in food chains, including macrophytes, zoobenthos, and bentho- and ichthyophagist fish, was estimated in the radiation-polluted region of the Yenisei river. Significant differences in the efficiency of the transfer of natural and technogenic radionuclides between components of different trophic levels were revealed. Substantial species-related differences in the accumulation of radionuclides in ichthyophagist fish from food were revealed. В© 2012 Pleiades Publishing, Ltd.

Transfer of americium-241 from food and water to organs and tissues of the crucian carp * / T. Zotina [et al.] // Radioprotection. - 2011. - Vol. 46, Is. 6 SUPPL. - S69-S73, DOI 10.1051/radiopro/20116648s . - ISSN 0033-8451
Аннотация: The transfer of transuranium element americium-241 (241Am) from food and water to organs and tissues of freshwater fish (Carassius auratus gibelio, crucian carp) has been investigated in laboratory experiments. The fishes were fed with homogenized biomass of submerged macrophytes labeled with 241Am, through catheter. For the first two days after force-feeding, fishes excreted up to 80% of ingested americium, for four days - 98%. 241Am was registered in internal organs and tissues that had no direct contact with americium (liver, bones, muscles) as early as two days after the feeding and after eight days, when the digestive tract was depurated. Among internal organs, the highest activity concentration was recorded in the liver (up to 427 Bq/kg). Activity concentration in bones (19-31 Bq/kg) was several times higher than in muscles, indicating the affinity of americium to bone tissue. Assimilation of 241Am in organs and tissues of crucian carp from water occurred mainly via the digestive tract too. В© 2011 EDP Sciences.

Аннотация: The source of radioactive contamination of the Yenisei River floodplain, including contamination with transuranic elements, is the Mining-and-Chemical Combine of the Russian Ministry of Atomic Energy, which has for many years been producing weapons-grade plutonium. Transuranic elements have been detected not only in the soil and sediment of the river but also in the biomass of aquatic plants. This work is an investigation of accumulation and release of 241Am by a submerged macrophyte of the Yenisei River (Elodea canadensis) in laboratory experiments. In 2000-2003, laboratory experiments were carried out with biomass of E. canadensis Mich. and filtered river water. The samples were collected from the Yenisei River upstream of the discharge of the Combine's radioactive effluent. The experiments showed that 241Am is accumulated by Elodea biomass: the activity concentration of 241Am can reach 3280 В± 240 Bq/g, with the concentration factor for 241Am 16 600 В± 2200 l/kg. Results of chemical fractionation have proved that in the course of 241Am accumulation by Elodea biomass, 241Am tightly bound to biomass increases from 11% to 27% of the total 241Am in the biomass. Release of 241Am from the decaying Elodea biomass has been evaluated experimentally. By the end of the experiment (lasting up to 127 days), the Elodea plants had lost up to 65% of their initial 241Am activity and the rate of 241Am release into the water environment reached 23 Bq/day.

Аннотация: The lab experiments showed that specific activity of 241Am achieves 3280В±240 Bc/g with 241Am accumulation coefficient = 16600В±2200 l/kg. The chemical fractionation results confirmed that 241Am can be strongly fixed by elodea biomass. At the end of long-term experiment the part of 241Am strongly bonded by the biomass reached 27% of total 241Am content in biomass. The accumulation process proceeds with 241Am redistribution towards decreasing of the part of exchange and adsorbed fractions and increasing of the part of organic and mineral fractions. Thus, the 241Am part in organic fractions doubled during the experiment and in mineral fraction - grew more than 10 times as compared with initial 241Am distribution.

Аннотация: Accumulation of americium ( 241Am) and plutonium ( 238,242Pu) and their distribution in cell compartments and biochemical components of the biomass of freshwater aquatic plants Elodea canadensis, Ceratophyllum demersum and Myrioplyllum spicatum and aquatic moss Fontinalis antipyretica have been investigated in laboratory experiments. Americium and plutonium taken up from water by Elodea canadensis apical shoots were mainly absorbed by structural components of plant cells (90% for 241Am; 89% for 238Pu and 82-87% for 242Pu). About 10-18% of isotope activity was recorded in the cytosol fraction. The major concentration (76-92%) of americium was bound to cell wall cellulose-like polysaccharides of Elodea canadensis, Myriophyllum spicatum, Ceratophyllum demersum and Fontinalis antipyretica, 8-24% of americium activity was registered in the fraction of proteins and carbohydrates, and just a minor concentration (<1%) in the lipid fraction. The distribution of plutonium in the biomass fractions of Elodea was similar to that of americium. Hence, americium and plutonium had the highest affinity to cellulose-like polysaccharides of cell walls of freshwater submerged macrophytes. В© 2011 Akademiai Kiado, Budapest, Hungary.

Аннотация: Experiments were carried out in which 241Am was added to water samples containing macrophytes of the Yenisei River, and the radionuclide absorption rates and concentration factors were determined for the plants. It has been shown that the water moss (Fontinalis antipyretica) has a higher capacity to accumulate 241Am than the Canadian pondweed (Elodea canadensis) does. The laboratory experiments revealed that the capacity of dead biomass of the Canadian pondweed to accumulate 241Am is twice higher than that of living biomass. In contrast, no significant increase in 241Am accumulation by dead biomass of the water moss has been recorded. The transuranic element 241Am was firmly fixed by the plant biomass and was not released into water in the course of long-duration experiments.

Metal Concentrations in the Ecosystem and Around Recreational and Fish-Breeding Pond Bugach / M. I. Gladyshev [et al.] // Water Resources. - 2001. - Vol. 28, Is. 3. - P288-296, DOI 10.1023/A:1010400807660 . - ISSN 0097-8078
Аннотация: Data of two field studies were used to analyze the concentrations of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb in the water, bottom deposits, zoobenthos, fish, and macrophytes of the Pond Bugach and in the soils near the pond. It was established that the majority of metals in the soils and bottom deposits correlate and their concentrations are governed by the universal geochemical factors of the region. The heavy metals were recognized that originate from anthropogenic sources and their concentrations were found to exceed the maximum admissible values for different components of the ecosystem. Five types of heavy metals migration were recognized in the soil-bottom deposits-zoobenthos-fish chain and in macrophytes. Statistically significant difference was found to exist between the concentrations of some heavy metals in the muscles of fish species with different food types (crucian carp and perch) as well as between the correlations of metals. The recorded concentrations were compared with the concentrations of metals measured in the last decade in other limnetic ecosystems in Siberia, Europe, North America, and China.

Аннотация: During three field seasons (June-September) of 1997-99 contents of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb were determined in compartments of ecosystem (surrounding soils, bottom sediments, water, zoobenthos, macrophytes, and fish) of a fish and recreation pond situated at the edge of Krasnoyarsk City (Siberia, Russia). Contents of most parts of metals in soils, water, and macrophytes significantly correlated with each other. As concluded, their contents were determined by natural, general, geochemical peculiarities of the region. Heavy metals, contents of which were higher than federal upper limits of concentration, were revealed. In muscles of fish with different feeding spectra - crucian and perch - concentrations of some metals differed significantly; correlation graphs for metals also had different structures. Comparison of our data with those on diverse aquatic ecosystems of Siberia, Europe, North America, and China published in the last decade was carried out. It was concluded that a distribution of heavy metals in the compartments of an aquatic ecosystem presently have to be determined for each particular water body until general regularities are discovered.

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: The laboratory testing of bottom sediments (BSs) from the Yenisei River containing different concentrations of technogenic radionuclides, heavy metals, and biogenic elements (N and P) based on aquatic such plants as Elodea canadensis (Canadian waterweed) and Myriophyllum spicatum (Eurasian watermilfoil) has revealed a higher sensitivity of roots to the general quality of BSs than shoots: shoot length (9%) < root length (11%) < root number (15%) in M. spicatum; shoot length (22%) < root length (42%) < root number (44%) in E. canadensis. In contrast to M. spicatum, the growth parameters of roots and shoots in E. canadensis have differed in a significant statistical manner between most BS samples. A reverse correlation has been found between the increase in shoot length and the activity of technogenic radionuclides in BSs, which is mostly significant in E. canadensis (r (2) = 0.90-0.95, p = 0.05). Since the growth of shoots and roots in E. canadensis has turned out to be more sensitive to changes in the quality of BSs than that in M. spicatum, E. canadensis can be considered more prospective for biotesting BSs.

Аннотация: The bioaccumulation of actinide Am-241 from food and water in bodies of freshwater fish (Carassius auratus gibelio, silver crucian carp) has been investigated in laboratory experiments. Homogenized biomass of submerged macrophytes labeled with Am-241 was injected into the fish gullet. Internal organs and tissues of crucian carp could be ranked according to activity concentration of dietary Am-241 after depuration of the digestive tract as follows: liver > gonads > bones > muscles. Accumulation of waterborne Am-241 in internal organs and tissues of crucian carp mainly occurred via the digestive tract. While the concentration of Am-241 in liver of crucian carps decreased during depuration time, its concentration in bones increased indicating slower transfer of Am-241 to skeleton compared to muscles and liver. The retention of dietary Am-241 in the bodies of crucian carp reached 35%-46% of ingested Am-241: 20%-31% was retained in liver, 0.6%-0.8% in skeleton, and 1.4%-2.0% in muscles. The concentration factor of Am-241 from water was 0.4 for the whole body, 0.3 for liver, 0.01 for muscles, and 0.01 for skeleton. Trace amounts of Am-241 were recorded in viscera and muscles of a wild population of silver crucian carp inhabiting a radioactively contaminated part of the Yenisei River.

Аннотация: During three field seasons (June-September) of 1997-99 contents of Na, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, Cr, Ni, Cd, and Pb were determined in compartments of ecosystem (surrounding soils, bottom sediments, water, zoobenthos, macrophytes, and fish) of a fish and recreation pond situated at the edge of Krasnoyarsk City (Siberia, Russia). Contents of most parts of metals in soils, water, and macrophytes significantly correlated with each other. As concluded, their contents were determined by natural, general, geochemical peculiarities of the region. Heavy metals, contents of which were higher than federal upper limits of concentration, were revealed. In muscles of fish with different feeding spectra-crucian and perch-concentrations of some metals differed significantly; correlation graphs for metals also had different structures. Comparison of our data with those on diverse aquatic ecosystems of Siberia, Europe, North America, and China published in the last decade was carried out. It was concluded that a distribution of heavy metals in the compartments of an aquatic ecosystem presently have to be determined for each particular water body until general regularities are discovered.

Аннотация: Submersed freshwater macrophytes are considered as relevant indicators for use in bulk bottom sediment contact tests. The purpose of this study was to estimate the validity of endpoints of aquatic plant Elodea canadensis for laboratory genotoxicity testing of natural bottom sediments. The inherent level of chromosome abnormalities (on artificial sediments) in roots of E. canadensis under laboratory conditions was lower than the percentage of abnormal cells in bulk sediments from the Yenisei River. The percentage of abnormal cells in roots of E. canadensis was more sensitive to the presence of genotoxic agents in laboratory contact tests than in the natural population of the plant. The spectra of chromosomal abnormalities that occur in roots of E. canadensis under natural conditions in the Yenisei River and in laboratory contact tests on the bulk bottom sediments from the Yenisei River were similar. Hence, chromosome abnormalities in roots of E. canadensis can be used as a relevant and sensitive genotoxicity endpoint in bottom sediment-contact tests. © 2015 Elsevier Inc.

Аннотация: We estimated the seston elemental composition (C, N, P) and its ratio in pelagic and littoral zones of mesotrophic shallow Lake Obsterno during two contrasting seasons, as well as the influence of macrophyte beds on the seston stoichiometry. In the both pelagial and littoral zones in summer the C : N ratio was small, 4.62 and 7.05 respectively. But it increased slightly during autumn to 5.66 in pelagic samples against 8.33 in littoral ones. The large N : P ratio and the small phosphorus content specially in the macrophyte covered littoral zone equal to 57.7 in July against 22.47 in September suggest a high level of phosphorus limitation in the littoral locations as a possible mediated reason suppressing zooplankton abundance in summer. Our results in the both pelagial and littoral habitat showed a highly P limited situation in which the N : P ratio was larger in littoral with macrophyte than in pelagial zones. The obtained data of littoral seston stoichiometry were recorded for the first time and exceeded the classical Redfield ratio. The elemental imbalance between macrophyte covered littoral and pelagial suggest that nutrients, especially P, are more limiting in macrophyte beds in summer due to the resource competition between phytoplankton and macrophytes for nutrients, a poor food quality, low zooplankton abundance, as well as its poor taxon-specific elemental ratio in summer.

Аннотация: Diverse, multidirectional changes in biochemical composition of seston, plankton, and fish fry are detected in the coastal zone of a plain reservoir in the vicinity of a semiaquatic bird colony during vegetation season with extra high water level. Under these conditions, specific patterns of phyto- and zooplankton structure and quantitative characteristics, that, as was found out earlier, result from the vital activity of birds belonging to the family Ardeidae (namely, raising the share of mixotrophic phytoflagellates and copepods in plankton species composition) are leveled out. The main role in this process belongs to decomposition of immersed vegetation in the coastal zone, development of littoral macrophytes, and trophic relationships between algae and invertebrates. However, increase in atmospheric precipitation leads to increase in copepods abundance, which seems to be related to fast and intensive inflow of nitrogen-rich products of birds' vital activity. Due to this, during the whole period of observations, the following tendencies are revealed in biochemical composition of seston, plankton, and fish fry in the vicinity of the bird colony: 1) concentrations of carbon, nitrogen, and phosphorus and their ratios turn out to be auspicious for predominance of diatoms and mixotrophic phytoflagellates, rich in docosahexaenoic acid (DSA); 2) the abundance of phytoplankton, rich in polyunsaturated essential fatty acids (PEFA), favors propagation of those planktonic crustaceans which contain significantly more DSA and are more valuable food items for fish; 3) predominance of zooplankters, rich in PEFA, leads to higher concentration of PEFA in fry fish tissues, which, in certain periods, turns out to be advantageous for successful development and growth of dominant species of fish fry,such as roach, bream, white bream, and perch, by comparison with the test site.

Аннотация: Accumulation of essential/beneficial and non-essential chemical elements by submerged (Stuckenia pectinata (L.) Borner) and emergent (Phragmites australis (Cav.) Trin. ex Steud.) rooted macrophytes in three water bodies was studied as dependent on water salinity (specific conductivity) and main environmental factors (temperature, pH of water, growing period, element contents in water and sediments). Inductively coupled plasma optical emission spectrometry (ICP - OES) was used for the element detection in the plants, sediments, and water. Multivariate statistics redundancy analysis (RDA) showed that investigated factors together explained 37.8 - 44.7% and 29.9 - 42.6% of the essential/beneficial and non-essential elements variability, respectively, whereas salinity was one of the main factors determining the accumulation of a number of elements (Mg, S, Na, Li, Sr, Sb) by the macrophytes. A decrease in the essential element contents (K, P, N, Cu, Zn) was observed in both species of the macrophytes during the growing season. Environmental factors (salinity, growing period, and pH) were more significant than the element contents in water and the sediments for the essential/beneficial element accumulation by two species of the macrophytes. The element contents in the sediments to a greater extent determined non-essential element accumulation by P. australis than by S. pectinata. The study showed that the efficiency of using P. australis and S. pectinata for remediation of aquatic ecosystems contaminated by heavy metals should not decrease with a salinity increase. © 2020 Elsevier Masson SAS

Long-term trends and speciation of artificial radionuclides in two submerged macrophytes of the Yenisei River: A comparative study of Potamogeton lucens and Fontinalis antipyretica / T. Zotina, D.

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 54Mn, 58Co, 60Co, 65Zn, 137Cs, and 152Eu 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 (R2 > 0.7) positive correlation (p < 0.05) was obtained for 60Co, 65Zn, and 152Eu. Concentrations of 60Co, 137Cs, and 152Eu 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. © 2020 Elsevier Ltd
