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.

Content of metals in compartments of ecosystem of a Siberian pond / M. I. Gladyshev [et al.] // Archives of Environmental Contamination and Toxicology. - 2001. - Vol. 41, Is. 2. - P157-162, DOI 10.1007/s002440010233 . - ISSN 0090-4341

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: It has been shown for the first time that Cd2+ ions induce substantial bioluminescence of a Ca2+-binding photoprotein: recombinant obelin. The optimum pH for the bioluminescent rr:action in the presence of Cd2+ ions is pH 6. The intensity, L, of the light emission for the Cd2+ ions is 75% of the intensity of the signal in the presence of Ca2+. The quantum yields of the reactions in the presence of Cd2+ and Ca2+ are 0.18 and 0.24 respectively. The slope of the straight line (between 5 and 90% of L,,) in the coordinates of log(L/(L(max) - L)) vs. log([Cd2+]) is 1.75 +/- 0.06, which indicates positive cooperative character of this reaction. At a concentration exceeding 1 . 10(-3) M, Cd2+ inhibits the bioluminescent reaction.

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.
