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.

Trace elements exchange in experimental closed life support systems [Text] / I. V. Gribovskaya, V. Y. Rygalov ; ed. ya, IV Gribovs // SIXTH EUROPEAN SYMPOSIUM ON SPACE ENVIRONMENTAL CONTROL SYSTEMS, VOLS 1 AND 2. Ser. ESA SPECIAL PUBLICATIONS : EUROPEAN SPACE AGENCY, 1997. - Vol. 400: 6th European Symposium on Space Environmental Control Systems (MAY 20-22, 1997, NOORDWIJK, NETHERLANDS). - P. 859-862. - Cited References: 0 . - ISBN 0379-6566. - ISBN 92-9092-283-4

Аннотация: Measurements of trace elements incoming and exiting ''Bios-3'' biological-engineering life support system evidence presence of a source of these elements inside the system. This source is, most probably, structural units (steel walls, hose rubber, plastic coatings), catalysts of the thermal catalytic incinerator, expanded clay aggregate mechanically fixing plants and so on. The trace elements are received by the nutrient solutions and build up in the plant biomass. As a consequence the crew may receive elevated doses of such trace elements as aluminum, lead, nickel, chromium. To reduce income of trace elements to LSS requires thorough selection and preliminary treatment of structural materials with reduced desorption capacities and running-in of the system in idle mode prior to exploitation. This mode involves operation of the engineering part of the system (without plants and humans, but with nutrient solutions) for several months.

Аннотация: In this work, the products accompanying fullerene and metallofullerene synthesis in a carbon plasma jet are briefly characterized. It is shown that in the thermolysis residual there are multiwall nanotubes and turbostatic graphite. Nickel was introduced into carbon plasma, several kinds of magnetic clusters are formed which were studied by the EPR method.

Ni2+-zeolite/ferrosphere and Ni2+-silica/ferrosphere beads for magnetic affinity separation of histidine-tagged proteins / T. A. Vereshchagina [et al.] // Dalton Trans. - 2016. - Vol. 45, Is. 4. - P1582-1592, DOI 10.1039/c5dt03827h . - ISSN 1477-9226

Аннотация: Magnetic Ni2+-zeolite/ferrosphere and Ni2+-silica/ferrosphere beads (Ni-ferrosphere beads - NFB) of a core-shell structure were synthesized starting from coal fly ash ferrospheres having diameters in the range of 0.063-0.050 mm. The strategy of NFB fabrication is an oriented chemical modification of the outer surface preserving the magnetic core of parent beads with the formation of micro-mesoporous coverings. Two routes of ferrosphere modification were realized, such as (i) hydrothermal treatment in an alkaline medium resulting in a NaP zeolite layer and (ii) synthesis of micro-mesoporous silica on the glass surface using conventional methods. Immobilization of Ni2+ ions in the siliceous porous shell of the magnetic beads was carried out via (i) the ion exchange of Na+ for Ni2+ in the zeolite layer or (ii) deposition of NiO clusters in the zeolite and silica pores. The final NFB were tested for affinity in magnetic separation of the histidine-tagged green fluorescent protein (GFP) directly from a cell lysate. Results pointed to the high affinity of the magnetic beads towards the protein in the presence of 10 mM EDTA. The sorption capacity of the ferrosphere-based Ni-beads with respect to GFP was in the range 1.5-5.7 mg cm-3. © The Royal Society of Chemistry.

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.

Effect of nanoparticles in growth of test - Bacteria / S. V. Stolyar, L. A. Chekanova, R. N.

Аннотация: Confident effect of five magnetic composite nanoparticles (FeP@Ag, FeP@Pd, CoP, NiP, Fe2O3@A) on growth of test bacteria colonies (Acinetobacter baumannii, scherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus) in five replicates each is considered. Reliable inhibitors of colonies of all five test bacteria were nanoparticles FeP@Ag. CoP nanoparticles are reliable inhibitors of growth of 4 test bacteria (except for test bacteria Escherichia oli). NiP nanoparticles are reliable inhibitors of growth of 2 test bacteria: Escherichia oli and Klebsiella pneumoniae. Bacteria Escherichia oli were most sensitive to the effect of magnetic nanoparticles; and bacteria Pseudomonas aeruginosa and Staphylococcus aureus were most resistant to the effect of magnetic nanoparticles. The prospects of the method are in the possibility of multiple reuse of the magnetic particles with antimicrobial properties for bacterial decontamination of the studied sources of water and removal of magnetic nanoparticles from the treated liquids by electromagnet. The method can find use in water treatment facilities for household, Industrial and medical wastes. © Published under licence by IOP Publishing Ltd.
