Аннотация: The influence of some chemical substances on luminous bacteria was studied to elucidate the interrelation between the xenobiotics action on bacterial luminescence and cell ultrastructure. Such substances as quinones, phenols, chlorides of heavy metals (in concentrations of substances inhibiting luminescence by 50%) resulted in damaging effects upon bacteria: a lot of cells had damage of membranes due to changes in their permeability. It was found that the high concentration of EDTA and toluene decreased the luminescence and caused the condensation of DNA-fibrils and the cell damage after long-term and short-term action. The low concentration of EDTA and toluene did not decrease the bacterial luminescence; the noticeable damage of cell membranes did not take place during short-term treatment. However, the long action of these substances changed the membrane permeability resulting in increased sensitivity of bacterial luminescence to some toxic substances.

The influence of microbial associations on germination of wheat seeds and growth of seedlings under impact of zinc salts / L. A. Somova, N. S. Pechurkin // Advances in Space Research. - 2009. - Vol. 43, Is. 8. - P1224-1228, DOI 10.1016/j.asr.2008.12.008 . - ISSN 0273-1177

Аннотация: The life support systems (LSS) for long-term missions are to use cycling-recycling systems, including biological recycling. Higher plants are the traditional regenerator of air and producer of food. They should be used in many successive generations of their reproduction in LSS. Studies of influence of microbial associations on germination of wheat seeds and on growth of seedlings under impact of heavy metals are necessary because of migration of heavy metals in LSS. Microbial associations are able to stimulate growth of plants, to protect them from pathogenic organisms and from toxicity of heavy metal salts. The goal of this work was to investigate effect of microbial associations on the germination of wheat seeds and on the growth of seedlings under impact of different concentrations of ZnSO4. The results of investigations showed that:(1)Zinc salt had an adverse effect on germination of wheat seeds, beginning with concentrations of 8 MPC (Maximum Permissible Concentration) and higher.(2)Microbial associations (concentrations -104 to 107 cells/ml) were able to decrease (partly or completely) the adverse effect of ZnSO4 on germination of wheat seeds.(3)Concentrations (104-107 cells/ml) of microbial associations were able to decrease partly the adverse effect of zinc salts (intervals: from 1 to 32 MPS{cyrillic}) on the growth and development of wheat plantlets during heterotrophic phase.(4)The root system of plants was more sensitive to the adverse effect of ZnSO4 than shoots of plants.

Аннотация: The addition of metallic Ir and Pt to a fullerene-forming, atmospheric-pressure plasma reactor was found to influence the generation of carbonaceous products. It was observed that the added metals were efficiently dispersed into the plasma and that their presence increased the yield of fullerenes. The addition of Ir led to a noticeable shift in the fullerene distribution towards C-60, whereas the addition of Pt increased the proportion Of C-60 oxides and decreased the proportion of higher fullerenes. Addition of Ir also caused a reduction of the soot particle size and the formation of a considerable quantity of carbon nanotubes.

The effect of radionuclide and heavy metal contamination of the Yenisei River on cytogenetics of aquatic plant Elodea canadensis / A. Bolsunovsky [et al.] // Radioprotection. - 2009. - Vol. 44, Is. 5. - P83-88, DOI 10.1051/radiopro/20095021 . - ISSN 0033-8451
Аннотация: The study was done to determine concentrations of radionuclides and heavy metals and to evaluate the frequency of chromosomal aberrations in samples of Elodea canadensis, a submerged plant, collected in different parts of the Yenisei River. Samples were collected in the area subjected to radioactive impact of theMining-and-Chemical Combine (MCC) at Zheleznogorsk and in the control areas, upstream of the MCC. The investigations showed that Elodea biomass in the area affected by MCC operation contained a long inventory of artificial radionuclides typical of the MCC discharges. Upstream of the MCC, in the control sampling areas, the sediments and the Elodea biomass contained only one artificial radionuclide - 137Cs. Thus, the exposure doses to Elodea shoots and roots upstream of the MCC are small (not more than 8 ?Gy/d) and the main contribution to them is made by natural radionuclides. At the MCC discharge site (the village of Atamanovo) and downstream of it, the total dose rate increases almost an order of magnitude, reaching its maximal values - 72 ?Gy/d for Elodea shoots and 58 ? Gy/d for roots. Cytogenetic investigations of Elodea roots showed that at the MCC discharge site (the village of Atamanovo) and downstream of it the occurrence of chromosomal aberrations in ana-telophase and metaphase cells of Elodea was considerably higher than in the control area. It is highly probable that this simultaneous dramatic increase in the total exposure rate and the occurrence of chromosomal aberrations in Elodea is associated with the radiation factor. It is suggested that Elodea is affected not only by the radiation factor but also by the chemical factor - toxicity of heavy metals. В© 2009 EDP Sciences.

Аннотация: In cold smoked species of genus Coregonus, identified by molecular genetic analysis, contents of fatty acids and heavy metals and arsenic were measured. The highest content of sum of long-chain polyunsaturated fatty acids of omega-3 family (LC-PUFA), namely eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids, 6.53 +/- 0.78 mg g(-1) wet weight, was characteristic of tugun Coregonus tugun. This is the first quantitative estimation (mg LC-PUFA per g of product) of the nutritive value of smoked fish. Thus, to obtain a daily personal doze of EPA + DHA of 1 g, recommended for prevention of cardiovascular diseases, one needs to consume 153 g of the smoked tugun. Metals contents did not exceed standards for fish meat except Pb in least cisco Coregonus sardinella. Accordingly, values of hazard quotients, which estimate benefit-risk ratio of fish intake, indicate that most of the smoked fish species are safe product for human nutrition, except least cisco regarding Pb content.

Seasonal variations of metal concentrations in periphyton and taxonomic composition of the algal community at a Yenisei River littoral site / O. V. Anishchenko [et al.] // Central European Journal of Biology. - 2010. - Vol. 5, Is. 1. - P125-134, DOI 10.2478/s11535-009-0060-y . - ISSN 1895-104X
Кл.слова (ненормированные):
Heavy metals -- Periphyton -- Seasonal dynamics -- algae -- Chlorophyta -- Cyanobacteria -- Ulothrix zonata
Аннотация: The concentrations of metals K, Na, Ca, Mg, Fe, Mn, Zn, Cu, Ni, Pb, Co and Cr, in the water and periphyton (epilithic algal communities) were studied at a site in the middle stream of the Yenisei River (Siberia, Russia) during three years using monthly sampling frequencies. Despite considerable seasonal variations in aquatic concentrations of some metals, there was no correlation between metal contents in the water and in periphyton. Seasonal concentration variations of some metals in periphyton were related to the species (taxonomic) composition of periphytic microalgae and cyanobacteria. Enhanced levels of Ni and Co in periphyton in late autumn, winter, and early spring were likely caused by the predominance of cyanobacteria in the periphytic community, and annual maximum levels of K in periphyton in late spring and early summer were attributed to the domination of Chlorophyta, primarily Ulothrix zonata.

Кл.слова (ненормированные):
Resting eggs -- Resistance -- Heavy metals -- Ionizing radiation -- Toxicity
Аннотация: Many Cladocera species under unfavourable conditions produce resting eggs that can survive for years in deep diapause. Resting eggs form egg banks at the bottom sediments, which serve as a source of genetic diversity and replenish the population after periods of decline. Despite the obvious importance of resting eggs for the ecosystem functioning, studies assessing the sensitivity of resting eggs to different toxicants are scarce. We reviewed published data on the sensitivity of resting eggs to the effect of heavy metals, organic pollutants and ionizing radiation. Analysis shows that the effects of toxicants of different types on resting eggs will have different environmental consequences. Egg banks may suffer from prolonged contact of dormant eggs with heavy metals. However, the ecological relevance of these effects is low, since the effective concentrations of toxicants must be very high. In addition, the effect of heavy metals on resting eggs is not transmitted to hatchlings from exposed eggs. Taking into account high toxicity of heavy metals to active animals, we assume that the toxic effect of heavy metals is critical for active zooplankters and relatively safe for resting stages. Accumulation of artificial radionuclides in bottom sediments can have a significant impact on aquatic ecosystems through chronic effects both on survival of resting eggs and on the life cycle parameters of animals hatched from irradiated eggs. Resting eggs during reactivation are more sensitive to the effect of ionizing radiation. Pesticides and complex chemical compounds produce similar toxic effects on both resting eggs and life history parameters of hatchlings from exposed resting eggs. The bottom line is that to predict the effect of contamination of bottom sediments by different pollutants on the ecosystem structure and functioning, it is highly important to investigate the viability of the resting eggs under a wide range of concentrations of various toxicants and different durations of direct contact of eggs with toxicants.

Аннотация: The paper considers mechanisms of detoxification of pollutant solutions by water-soluble humic substances (HSs), natural detoxifying agents. The problems and perspectives of bioassay application for toxicity monitoring of complex solutions are discussed from ecological point of view. Bioluminescence assays based on marine bacteria and their enzymes are of special attention here; they were shown to be convenient tools to study the detoxifying effects on cellular and biochemical levels. The advantages of bioluminescent enzymatic assay for monitoring both integral and oxidative toxicities in complex solutions of model pollutants and HS were demonstrated. The efficiencies of detoxification of the solutions of organic oxidizers and salts of metals (including radioactive ones) by HS were analyzed. The dependencies of detoxification efficiency on time of exposure to HS and HS concentrations were demonstrated. Antioxidant properties of HS were considered in detail. The detoxifying effects of HS were shown to be complex and regarded as 'external' (binding and redox processes in solutions outside the organisms) and/or 'internal' organismal processes. The paper demonstrates that the HS can stimulate a protective response of bacterial cells as a result of (1) changes of rates of biochemical reactions and (2) stabilization of mucous layers outside the cell walls. Acceleration of auto-oxidation of NADH, endogenous reducer, by HS was suggested as a reason for toxicity increase in the presence of HS due to abatement of reduction ability of intracellular media.

Аннотация: The concentrations of nutrients in water and the total concentrations of metals were determined in water and bottom sediments of four lakes in Ergaki Ridge, which differ in their geographic, morphometric, and hydrophysical characteristics. By the concentration of all examined metals in water and bottom sediments, the lakes can be divided into two groups. The first group includes lakes Oiskoe and Svetloe, which feature large size and depth, while the second group includes small and shallow lakes Raduzhnoe and Karovoe. The concentrations of metals are compared with data obtained for different lakes of other mountain regions and with standards established for their concentrations in water and sediments. The concentrations of Zn and Cu in the sediments of Lake Svetloe were found to exceed the threshold, introduced by international standards, below which no impact on biota is recorded. © 2015, Pleiades Publishing, Ltd.

Model assessment of the migration capability of transuranium radionuclides (241Am and Pu isotopes) and 152Eu in the system bottom sediments-Yenisei river water by chemical fractionation technique / L. G. Bondareva [et al.] // Radiochemistry. - 2005. - Vol. 47, Is. 4. - P415-421, DOI 10.1007/s11137-005-0112-8 . - ISSN 1066-3622
Аннотация: Sorption of radiotracers 241Am and 242Pu and weighable amounts of uranium and stable Eu on bottom sediments in the simulated system bottom sediments-Yenisei river water was studied. At a contact time of 40 min these metals are completely sorbed on the bottom sediments, presumably via association with organomineral complexes and hydrated gels. Along with sorption, these metals can form soluble complexes and stable colloids (pseudocolloids). The distribution factors of 241Am and 242Pu, and stable Eu in the simulated system between bottom sediments and liquid phases were calculated from the results of sorption experiments. The introduced 241Am and 152Eu initially present in radioactively contaminated bottom sediments of the Yenisei river show similar pattern of distribution over differently mobile fractions. The distribution of weighable amounts of stable Eu significantly differs from that of initially present 152Eu and tracer 241Am due to decelerated sorption of stable Eu and its considerably higher concentration. A significant part of 242Pu, 241Am, and 152Eu is associated with mobile fractions of bottom sediments, which, under certain environmental conditions, can pass into river water as migrating species.

Аннотация: Optically enhanced biosensing strategies are prerequisites for developing miniature and highly sensitive multiplexed analytical platforms. Such smart biosensing systems are highly promising for use in the fields of biomedicine and environmental monitoring. Optical signal enhancement during bioassays is attributed to the complex opto-electronic interactions of incoming photonic signals at the nanomaterial interface. Research on the use of metals other than gold and silver for such purposes tends to extend the spectral window to observe luminescence enhancement effects. Such manifold increase in luminescence may be explained by the principles of plasmon coupling, directional emission led high collection efficiency, Rayleigh scattering and related opto-electronic events. The present review begins with a mechanistic description of important phenomena associated with metal-induced luminescence enhancement, particularly focusing on the origin of metal-enhanced luminescence. This review further analyses the hybrid nanostructure capabilities responsible for maintaining unique opto-electronic properties during bio-functionalisation. Current research trends in this area, future scope of this field for designing useful bioassays and concluding remarks are then discussed. (C) 2017 Elsevier B.V. All rights reserved.

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: 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.

Аннотация: In the course of monthly sampling in 2008-2010, two regions of the littoral of the Yenisei river were compared. One of these regions (conventionally pure) was situated upstream of Krasnoyarsk, while the other (conventionally polluted) was downstream of Krasnoyarsk. The concentrations of heavy metals, oil products, phenols, biogenic elements and essential polyunsaturated fatty acids (PUFAs) in various components of the river ecosystem were determined. It was discovered that the anthropogenic pollution causes a decrease in the resources of essential PUFA in the biomass of the upper links of the food chain of the river ecosystem.

Hydrochemical Indicators of Water Quality in the Norilsk–Pyasino Lake–River System after a Diesel Fuel Spill at Norilsk Heat and Power Plant 3 in 2020 / D. M. Bezmaternykh, A. V. Puzanov, A. V.

Аннотация: Abstract: The results of a hydrochemical analysis of the consequences of an accidental fuel release in the Norilsk–Pyasino water system are presented. The pollution of watercourses in the catchment of Lake Pyasino (a nameless (Nadezhdinsky) creek, the Daldykan River, and the Ambarnaya River) with oil products, phenols, easily oxidizable and hard to oxidize organic matter (COD, PO, and BOD5), suspended solids, inorganic salts, and heavy metals at concentrations exceeding the background levels and MPC for fishery water bodies, as well as a temperature rise in waters of the nameless creek near Norilsk Heat and Power Plant 3 (CHPP-3), have been revealed. The contamination of the surface water decreases downstream in ascending order: nameless creek–Daldykan River–Ambarnaya River. The occurrence of oil products, phenols, and organic substances in the surface waters 2 months after the fuel spill is obviously due to their diffusion from the river bottom sediments, which accumulated a considerable quantity of heavy fractions of diesel fuel after the accident. Increased concentrations of Ca, Cu, Zn, Mn, Co, and Ni in the waters of the studied tributaries of Lake Pyasino are not directly related to the accident; they result from the general technogenic pollution of the territory and the increased geochemical background for these elements. Water contamination with oil products and phenols in the studied areas of Lake Pyasino (its central and northern parts) and the Pyasino River has not been detected. However, Pb concentrations exceed the MPC and Cd is recorded in the water, which is probably due to pollutants that accumulated in previous years. © 2021, Pleiades Publishing, Ltd.

High Resistance of Resting Eggs of Cladoceran Moina macrocopa to the Effect of Heavy Metals / N. Oskina [et al.] // Bull. Environ. Contam. Toxicol. - 2018, DOI 10.1007/s00128-018-2473-7 . - Article in press. - ISSN 0007-4861

Аннотация: The research aimed to determine critical concentrations of heavy metals at which survival of resting eggs of the cladoceran Moina macrocopa is negatively affected. Resting eggs’ viability was not affected over a 30-days exposure towards copper, cadmium, zinc or nickel at concentrations up to 60–70 g/L. When resting eggs were exposed to sediment contaminated with heavy metals for 8 months, the hatching success was affected at 30 g copper/kg. Thus, resting eggs of Cladocera can tolerate heavy metals at concentrations that far exceed lethal concentrations of heavy metals to active life stage and exceed low or moderate levels of environmental pollution. Follow up investigation of life table parameters of hatchlings from resting eggs exposed to heavy metals demonstrated that neither lifespan nor fecundity of hatchlings differ from control animals. These results demonstrate that zooplankton may rapidly recover from resting egg bank once aquatic habitat becomes unpolluted. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.

Аннотация: Enzymatic luminescent systems are a promising tool for rapid detection of heavy metals ions for water quality assessment. Nevertheless, their widespread use is limited by the lack of test procedure automation and available sensitive handheld luminometers. Herein we describe integration of disposable microfluidic chips for bioluminescent enzyme-inhibition based assay with a handheld luminometer, which detection system is based on a thermally stabilized silicon photomultiplier (SiPM). Microfluidic chips were made of poly(methyl methacrylate) by micro-milling method and sealed using a solvent bonding technique. The composition of the bioluminescent system in microfluidic chip was optimized to achieve higher luminescence intensity and storage time. Results indicate that developed device provided comparable sensitivity with bench-scale PMT-based commercial luminometers. Limit of detection for copper (II) sulfate reached 2.5 mg/L for developed biosensor. Hereby we proved the concept of handheld enzymatic optical biosensors with disposable chips for bioassay. The proposed biosensor can be used as an early warning field-deployable system for rapid detection of heavy metals salts and other toxic chemicals, which affect bioluminescent signal of enzymatic reaction.

Export of biomass and metals from aquatic to terrestrial ecosystems via the emergence of dragonflies (Insecta: Odonata) / O. N. Popova [et al.] // Contemp. Probl. Ecol. - 2016. - Vol. 9, Is. 4. - P458-473, DOI 10.1134/S1995425516040090 . - ISSN 1995-4255

Аннотация: Long-term monitoring of the abundance and spatial distribution of 18 widespread species of Odonata has made it possible to assess their contribution to the export of aquatic productivity that entered the Barabinsk forest-steppe ecosystem. The annual emergence of Odonata varies from 0.8 to 4.9 g/m2 of the land area and from 2.3 to 13.3 g/m2 of the water area, which is 4–5 times larger than that in Diptera. The total flux of organic matter from water to terrestrial ecosystems remains relatively stable (sixfold interannual variability) irrespective of large interannual variations in the abundance of separate species (e.g., 42-fold interannual variability in Libellula quadrimaculata). The metal content was determined in nine Odonata species. Export of metals by dragonflies decreases in the series K > Na > Mg > Ca > Fe > Zn > Cu > Mn > Pb > Ni > Cr > Cd. Therefore, odonates appear to be quantitatively and qualitatively important providers of aquatic resources to the forest-steppe landscape of Western Siberia. © 2016, Pleiades Publishing, Ltd.
