Аннотация: This study is devoted to investigating the content of uranium isotopes in water of the Yenisei River and its tributaries within the territories affected by the operation of Rosatom plants (mining chemical combine, and electrochemical plant). Long-term monitoring of the 238U content by mass spectrometry carried out in two institutes of the Siberian Branch of the Russian Academy of Sciences first revealed the multiple excess of 238U over the background content in different areas of the Yenisei River basin, such as the region of the Yenisei River near the effluents of the mining and chemical combine (MCC), and the territories of the Bol'shaya Tel' and Kan rivers. In these regions, the 238U content in water reaches 2.1-4.0 ?g/l, which exceeds its content upstream from the MCC (0.3-0.6 ?g/l) by almost an order of magnitude. The studies of the isotopic composition of uranium in water samples, which were carried out at the Institute of Inorganic Chemistry, Siberian Branch, Russian Academy of Sciences, showed the presence of a technogenic isotope of uranium 236U in the samples from the Bolshaya Tel' River and revealed the deviation of the isotope ratio 238U/ 235U (167 В± 3 and 177 В± 3) from the equilibrium natural ratio ( 238U/ 235U = 138). These facts attest to the technogenic origin of part of the uranium in water of the Bol'shaya Tel' River connected with the activity of MCC. The excess uranium content in the Kan River requires additional studies to ascertain the fraction of uranium of technogenic origin connected with the activity of the electrochemical plant (ECP) (Fig. 1, Table 4).

Accumulation and release of 241Am by a macrophyte of the Yenisei River (Elodea canadensis) / A. Bolsunovsky, T. Zotina, L. Bondareva // Journal of Environmental Radioactivity. - 2005. - Vol. 81, Is. 1. - P33-46, DOI 10.1016/j.jenvrad.2004.10.012 . - ISSN 0265-931X

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.

Artificial radionuclides in aquatic plants of the Yenisei River in the area affected by effluents of a Russian plutonium complex / A. Bolsunovsky // Aquatic Ecology. - 2004. - Vol. 38, Is. 1. - P57-62, DOI 10.1023/B:AECO.0000020950.43944.ec . - ISSN 1386-2588

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.

Biotesting of Effluent and River Water by Lyophilized Luminous Bacteria Biotest / A. M. Kuznetsov, E. K. Rodicheva, S. E. Medvedeva // Field Analytical Chemistry and Technology. - 1998. - Vol. 2, Is. 5. - P267-275 . - ISSN 1086-900X

Аннотация: Waters of the Yenisei River, certain rivers and lakes of the Altai Territory, and effluents of some industrial factories in Krasnoyarsk were studied by luminous bacteria biotest Microbiosensor B17 677F. The lyophilized luminous bacteria Photobacterium phosphoreum from the IBSO collection were used to design this biotest. The bioluminescent test is based on bioluminescence quenching resulting from the action of water samples on luminous bacteria. The test results indicated locations and zones of impaired water quality. The heaviest pollution of water in the Yenisei River was recorded in the zones 0-116 km downstream from Krasnoyarsk (Krasnoyarsk and satellite towns). The effluents of most factories were found to be toxic. Underground and surface waters of some areas of the Altai Territory had different toxicity levels; there were deviations from the norm in most water samples taken from the different lakes and rivers. The data from this study show that the luminous bacteria biotest is simple and convenient, and that the results obtained are within acceptable levels of accuracy for the evaluation of the toxicity of effluent and river water. It takes no more than 30 min to do the biotest. It can be used in ecological monitoring like the Microtox toxicity test. В© 1998 John Wiley & Sons, Inc.

Antibiotic resistance of heterotrophic bacteria in Shira lake: Natural and anthropogenic impacts / T. I. Lobova, Yu. V. Barkhatov, L. Yu. Popova // Aquatic Microbial Ecology. - 2002. - Vol. 30, Is. 1. - P11-18 . - 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.
