Ключевые слова (''Своб.индексиров.''): biotest--bioluminescence--enzymes--environmental monitoring
Аннотация: The influence of several suites of pollutants (metallic salts, quinones, and phenols) on bacterial bioluminescence in vivo and in vitro (five test systems) was investigated. The sensitivity of bioluminescence to the different pollutants was evaluated, and inhibition constants were measured. The data obtained were shown to correlate with the physical and chemical characteristics of the substances and the structure of the bioluminescent systems. It has been found that three bioluminescent tests (water-soluble enzyme systems, immobilized enzyme systems, and bioluminescent bacteria) show higher sensitivity to pollutants and cover all types of widespread contamination. These tests were chosen as a set of bioluminescent assays for the detection of pollutants. (C) 1998 John Wiley & Sons, Inc.

Ключевые слова (''Своб.индексиров.''): paleolimnology--diatom algae--meromictic lake--sedimentation--cyclotella--choctawhatcheeana--aulacoseira valida--aulacoseira ambigua
Аннотация: Lake Shira as a meromictic lake is object of interest for paleolimnological studies. In May 2011 core samples were collected from the bottom of Lake Shira and the species composition of diatom algae, which serve as bioindicators of the state of the lake, were studied. In addition, in 2012, seasonal water samples and material from sediment traps were collected and the species composition of diatoms in them was analyzed. The results of the analysis showed that the lake, like in previous years of research, was dominated by Cyclotella choctawhatcheeana Prasad. Diatoms were found twice in the studied core above the white carbonate layers and were absent in other layers. The species living in the lake at present were observed down to the first white carbonate layer, including the predominant Cyclotella choctawhatcheeana. This fact presumably proves the consistency of the species composition of diatoms and the overall stable condition of the lake since 1946 (Rogozin et al., 2005). Down to the second white carbonate layer, the dominant species were Aulcosira valida (Grunow) Krammer and Aulcosira italica (Grunow) Simonsen. Nitzchia sigmodea (Nitzsch) W. Smith and Fragilaria construens var. venter (Ehrenberg) Grunow were also observed at these depths, dating approximately to 1655-1690. These are freshwater species that belong to the diatoms of arctic, alpine, and temperate latitudes, which develop in shallow waters under moderate temperature conditions. This fact suggests that Lake Shira was less salty in the middle and end of the 17th century than today.

Ключевые слова (''Своб.индексиров.''): fluorescent protein--coelenteramide--discharged photoprotein obelin--multicolor bioindicator--radiotoxicity
Аннотация: The study addresses the application of fluorescent coelenteramide-containing proteins as color bioindicators for radiotoxicity evaluation. Biological effects of chronic low-dose radiation are under investigation. Tritiated water (200 MBq/L) was used as a model source of low-intensive ionizing radiation of beta type. 'Discharged obelin,' product of bioluminescent reaction of marine coelenterate Obelia longissimi, was used as a representative of the coelenteramide-containing proteins. Coelenteramide, fluorophore of discharged obelin, is a photochemically active molecule; it produces fluorescence forms of different color. Contributions of 'violet' and 'blue-green' forms to the visible fluorescence serve as tested parameters. The contributions depend on the coelenteramide's microenvironment in the protein, and, hence, evaluate distractive ability and toxicity of radiation. The protein samples were exposed to beta radiation for 18 days, and maximal dose accumulated by the samples was 0.28 Gy, being close to a tentative limit of a low-dose interval. Increase of relative contribution of 'violet' fluorescence under exposure to the beta irradiation was revealed. High sensitivity of the protein-based test system to low-dose ionizing radiation (to 0.03 Gy) was demonstrated. The study develops physicochemical understanding of radiotoxic effects.

Предметные рубрики: HORMESIS
Аннотация: Five permanent sample plots (SPs; 200-250 trees per plot) were established in middle-aged high-grade suburban pine stands near the industrial city of Krasnoyarsk, Siberia, Russia. Needle damage, inventory parameters of the stands, and the defense response of the stem phloem were evaluated annually for the years 2002-2019 and attributed to acute or chronic toxic exposures (creeping fire or industrial pollutants, respectively). The results form a basis for using trees as bioindicators. A newly elaborated stem lesion test was formed from a hypothesis on the upward sugar transport for the regeneration of an injured crown, based on Eschrich's model of bidirectional sugar transport in the phloem. The formation of a phloem lesion was induced by inoculation of the stem with a mycelial extract of the ophiostomatoid fungus Ceratocystis laricicola. The lesion length and its shift relative to the inoculation hole were measured. An increase in the length of needles at early stages of stand weakening by pollutants was found to correspond to the hormesis model (Selye's adaptation syndrome). A possibility of assessing the chronology of pollutant toxicity and the duration of the recovery period after creeping fire was shown.

Заглавие : A long-term study of radionuclide concentrations in mushrooms in the 30-km zone around the Mining-and-Chemical Combine (Russia)
Место публикации : Isot. Environ. Health Stud.: Taylor and Francis Ltd., 2020. - Article in press. - ISSN 10256016 (ISSN), DOI 10.1080/10256016.2020.1718124
Аннотация: 137Cs concentrations were measured in mushrooms in an area affected by radioactive discharges of the Mining-and-Chemical Combine (MCC) (Rosatom, Russia) in 2002–2017. The sources of radionuclides in the study sites were global fallouts and waterborne and airborne radioactive discharges of the MCC. The mushroom species Suillus granulatus and S. luteus showed the highest 137Cs concentrations (140–7100 Bq kg?1) for this area. Over the entire monitoring period, no significant change in 137Cs concentration was observed in the Suillus spp. samples collected from the sites with the aerial deposition of radionuclides. In the floodplain site with the radionuclide deposition from water and air, a significant decrease in the average 137Cs concentration was observed in the period between 2004 and 2017: a three-fold decrease in Suillus spp. and a nine-fold decrease in Lactarius deliciosus. The effective half-lives of 137Cs in fruiting bodies of the mushrooms L. deliciosus and Suillus spp. in this site were 3.6 ± 0.6 and 9.2 ± 2.7 years, respectively. © 2020, © 2020 Informa UK Limited, trading as Taylor & Francis Group.
