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.

Аннотация: The Yenisei River, one of the largest rivers in the world, is contaminated with artificial radionuclides released by one of the Russian nuclear plants, which produces weapons-grade plutonium and has been in operation for many years. The aim of the study that was conducted between 1997 and 2002 was to investigate accumulation of artificial radionuclides by aquatic plants of the Yenisei River. The aquatic plants sampled were: Potamogeton lucens (shining weed) and Fontinalis antipyretica (water moss). The ?-spectrometric analysis of the samples of aquatic plants for artificial radionuclides has revealed a wide spectrum of long-lived and short-lived radionuclides. Artificial radionuclides such as 51Cr, 54Mn, 58Co, 60Co, 65Zn, 137Cs, and 152Eu were found in aquatic plants collected both near the plutonium complex and 194 km downstream in the river. The radiochemical analysis of aquatic plants revealed strontium and isotopes of plutonium. Fontinalis antipyretica had very high concentration factors of the principal radionuclides: 14220, 3110 and 500 of 51Cr, 46Sc and 239Np, respectively.

Аннотация: The study was done to investigate the content of manmade radionuclides in aquatic organisms of the Yenisei River near the Mining-and-Chemical Combine (MCC) and to estimate the exposure dose rates to organisms from various sources. The results of the investigation and calculations suggest that the main source of radioactive contamination of aquatic organisms is the coolant of the third MCC reactor, which is still being released into the Yenisei. Gamma-spectrometric analysis revealed 23 manmade radionuclides in the biomass of aquatic plants. The aquatic animal Phylolimnogammarus viridis and diatoms also contain manmade radionuclides. Among aquatic organisms, the highest dose rate is received by aquatic plants (up to 39 ?Gy/day). For most aquatic organisms under study, the dose received from the technogenic irradiation is an order of magnitude higher than the dose received from natural irradiation. The water moss (Fontinalis antipyretica) features the highest capacity to accumulate manmade radionuclides; hence, it accumulates the largest technogenic exposure dose among the study aquatic organisms.

Аннотация: We studied four-link food chain, periphytic microalgae and water moss (producers), trichopteran larvae (consumers I), gammarids (omnivorous - consumers II) and Siberian grayling (consumers III) at a littoral site of the Yenisei River on the basis of three years monthly sampling. Analysis of bulk carbon stable isotopes and compound specific isotope analysis of fatty acids (FA) were done. As found, there was a gradual depletion in 13C contents of fatty acids, including essential FA upward the food chain. In all the trophic levels a parabolic dependence of ? 13C values of fatty acids on their degree of unsaturation/chain length occurred, with 18:2n-6 and 18:3n-3 in its lowest point. The pattern in the ? 13C differences between individual fatty acids was quite similar to that reported in literature for marine pelagic food webs. Hypotheses on isotope fractionation were suggested to explain the findings. В© 2012 Gladyshev et al.

Water moss as a food item of the zoobenthos in the Yenisei River / G. S. Kalachova [et al.] // Central European Journal of Biology. - 2011. - Vol. 6, Is. 2. - P236-245, DOI 10.2478/s11535-010-0115-0 . - ISSN 1895-104X

Аннотация: Bryophytes are abundant in streams and are a habitat for many invertebrates, but their contribution to the diet of fluvial zoobenthos is still debated. To estimate the amount of bryophyte-derived organic matter assimilated by benthic invertebrates, we used a combination of fatty acid and stable isotope analyses during a four-year monthly study of a littoral site in the Yenisei River (Siberia, Russia). Acetylenic acids, which are highly specific biomarkers of the water moss Fontinalis antipyretica, were found in lipids of all dominant benthic animals: gammarids, ephemeropterans, chironomids and trichopterans. The dominant zoobenthic species, Eulimnogammarus viridis, had maximum levels of the biomarkers in its biomass during winter, and minimum levels in summer. The zoobenthos in the studied site regularly consume and assimilate bryophyte-derived organic matter as a minor supplemental food. This consumption increases in winter, when the main food source of the zoobenthos, epilithic biofilms, are probably scarce. В© 2010 Versita Warsaw and Springer-Verlag Wien.

Seasonal dynamics of fatty acids in the lipids of water moss Fontinalis antipyretica from the Yenisei River / G. S. Kalacheva [et al.] // Russian Journal of Plant Physiology. - 2009. - Vol. 56, Is. 6. - P795-807, DOI 10.1134/S1021443709060090 . - ISSN 1021-4437

Аннотация: Identification of lipid fatty acids (FA) and studying of their seasonal dynamics in water moss Fontinalis antipyretica from the Yenisei River were carried out by means of gas chromatography-mass spectrometry. FA composition of water moss was notable for a relatively low level of saturated acids and predominance of polyunsaturated acids (PUFA) with double bonds (accounting for more than 30% of total FA) and polyunsaturated acids with double and triple bonds (acetylenic acids, accounting for more than 40% of total FA). Among PUFA, ?- and ?-linolenic (18:3?3 and 18:3?6), arachidonic (20:4?6), and eicosapentaenoic (20:5?3) acids prevailed. Relative content of PUFA from ?3-family was the greatest in spring, and the level of PUFA from ?6-group was essentially the same throughout all the seasons. In the biomass of water moss, we identified seven acetylenic acids; among them octadeca-9,12-dien-6-ynoic (6a,9,12-18:3), octadeca-9,12,15-trien-6-ynoic (6a,9,12,15-18:4), and eicosa-11,14-dien-8-ynoic (8a,11,14-20:3) acids were predominant. For the first time, in the lipids of water moss we identified an acetylenic eicosa-11,14,17-trien-8-ynoic acid (8a,11,14,15-20:4). Relative content of acetylenic acids in the total FA was great throughout the entire period of investigation with the peak accumulation in summer. Owing to a steadily high level in the biomass of water moss and the lack of other producers of these acids in the ecosystem, acetylenic FA are highly specific biochemical markers useful for the investigation of trophic interactions between higher aquatic plants and zoobenthos.

Аннотация: Methods of atomic absorption, flame photometry, and emission spectral analysis were used to study the concentrations of metals in water and major ecosystem components of the Yenisei River upstream of Krasnoyarsk City (conventionally background area). The mean bulk concentrations of Al and Cu in water exceeded the MAC for water bodies used for fishery. Cu concentration in freshwater shrimp was found to be reliably higher than that in the link of primary producers (periphyton), and Cd concentration in caddis fly larvae was found to exceed that in water moss. The maximal concentrations of metals among the examined aquatic organisms were recorded in periphyton. Cr concentration in the muscles of Arctic grayling was found to exceed some international standards. В© 2009 Pleiades Publishing, Ltd.

Аннотация: Методом хромато-масс-спектрометрии проведена идентификация и изучена сезонная динамика ЖК липидов водного мха фонтиналиса (Fontinalis antipyretica), обитающего в р. Енисей. Спектр ЖК водного мха характеризовался относительно низким содержанием насыщенных кислот и преобладанием полиненасыщенных кислот (ПНЖК) с двойными связями (30% от суммы ЖК) и полиненасыщенных кислот с двойными и тройными связями 9ацетиленовых кислот, более 40% от суммы ЖК). Доминирующими ПНЖК являлись 'альфа'- и 'гамма'-линоленовая (18:3'омега'3 и 18:3'омега'6), арахидоновая (20:4'омега'6) и эйкозапентаеновая (20:5'омега'3) кислоты. Относительное содержание ПНЖК 'омега'3-семейства было максимальным весной, а ПНЖК 'омега'6-семейства достоверно не различалось во все сезоны года. В биомассе фонтиналиса идентифицировано семь ацетиленовых кислот, среди которых доминирующими являлись октадека-9,12-диен-6-иновая (6а,9,12-18:3), октадека-9,12,15-триен-6-иновая (6а,9,12,15-18:4) и эйкоза-11,14-диен-8-иновая (8а,11,14-20:3). Впервые в липидах фонтиналиса идентифицирована ацетиленовая эйкоза-11,14,17-триен-8-иновая кислота (8а,11,14,17-20:4). Относительное содержание ацетиленовых кислот в сумме ЖК было высоким на протяжении всего исследованного периода с максимальным накоплением летом. Благодаря постоянно высокому содержанию в биомассе водного мха и отсутствию других продуцентов данных кислот в экосистеме, ацетиленовые ЖК являются информативными высокоспецифичными биомаркерами при изучении трофических взаимодействий речной высшей растительности и зообентоса.

Аннотация: We investigated time-dependent trends of artificial radionuclides in aquatic moss, zoobenthos (amphipods and caddisfly larvae), and three abundant wild fish species (Northern pike, Arctic grayling, and Siberian dace) inhabiting the Yenisei River in the vicinity of the radioactive discharge site in 2007–2015, in a period before and after the shutdown of the last nuclear reactor plant at the Mining-and-Chemical Combine (MCC), which occurred in 2010. From our research, we learned that concentrations of short-lived radionuclides, whose discharges to the Yenisei either stopped or declined after the shutdown of the reactor plant at the MCC (24Na, 46Sc,51Cr, 54Mn, 58Co, 59Fe, 60Co, 65Zn, 103Ru, 141,144Ce, 152,154Eu, 239Np), decreased in biota samples as well. The ecological half-life (EHL) of 65Zn (0.4–0.7 y) was similar to the physical half-life of this isotope, the EHLs of 60Co (1.2–2.1 y) and 152Eu (1.8 y) were shorter than the physical half-lives of these isotopes. Concentration of 137Cs did not decrease significantly in biota of the Yenisei after the shutdown of the last reactor plant because the discharges of this radionuclide to the Yenisei continued at the same level. On a longer-term scale (since 1973 and since 1991), concentration of 137Cs in fish muscle had significantly decreased, following the decrease in annual discharges of this radionuclide to the Yenisei, and the EHL of 137Cs was estimated as 6.5–12.8 y. Statistically significant correlation with annual discharges of 137Cs was revealed for the concentration of this radionuclide in grayling (whole bodies and muscle); dace (muscle), and amphipods. Despite their ability to accumulate high concentrations of 137Cs, aquatic moss and caddisfly larvae (analyzed together with their stony casings) were not sensitive to interannual fluctuations in the releases of this radionuclide to the Yenisei. Among the analyzed fish species of the Yenisei, the highest activity concentration of 137Cs was revealed in pike (body and muscle), indicating biomagnification of this radionuclide in the top level of the trophic chain. © 2019 Elsevier Ltd
