Перевод заглавия: Influence of chemical pollutants on stability of forest soil microbiocenoses (natural model experiments)
Аннотация: Проведено исследование влияния различных концентраций (10, 30, 50, 100, 150, 300 предельно допустимых концентраций) фтористых и сернистых загрязнителей (Na2SO3, NaF и Na2SO3 + NaF) на почвы повышенной буферности лиственничника мертвопокровного Погорельского Бора Красноярской лесостепи. В ответ на обработку высокими концентрациями фтористых и сернистых соединений повышались интенсивность дыхания микроорганизмов и значения микробного метаболического коэффициента, уменьшались микробная биомасса и энзиматическая активность по сравнению с контролем в 1.3–2.7 раза. К концу вегетации экофизиологическое состояние микробоценозов опытных участков стабилизировалось.

Assessment of the state of soil microbial cenoses in the forest-tundra zone under conditions of airborne industrial pollution
/ A. V. Bogorodskaya [et al.] // Eurasian Soil Sci. - 2012. - Vol. 45, Is. 5. - P521-531, DOI 10.1134/S106422931205002X. - Cited References: 46

Аннотация: The quantitative and functional responses of soil microbial cenoses in the forest-tundra zone to pollution have been studied in the area exposed to emissions from the Norilsk Mining and Metallurgical Works. The strongest structural and functional disturbances of the soil biota have been recorded on the plots with completely destroyed vegetation. A decrease in the content of microbial carbon and an elevated respiration rate in the technogenically transformed soils provide evidence for the functioning of the microbial communities under stress caused by the continuous input of aggressive pollutants. The degree of transformation and the contents of technogenic elements (Ni, Cu, Co, Pb, and S) in the organic horizons of the forest-tundra soils are the major factors affecting the development and functioning of the soil microbial cenoses.

Аннотация: Environmental conditions causing stress have a significant effect on the generative organs of Scotch pine. The parameters characterizing pine pollen are subject to significant interannual variations and are closely connected with weather and climatic conditions in the period of pollen formation. Airborne pollutants affect the quality of pine pollen, which is especially apparent in the years favorable for the formation of microspores. The ability of Scotch pine pollen to germinate and form pollen tubes in the regions with different technogenic loads proved to be significantly lower than in tree stands of the background areas.

Аннотация: Structure of crown and viability of generative organs of Siberian fir were studied in disturbed forest ecosystems near Baikal Lake. The crown structure changes in damaged trees: a zone of subapical drying appears and apical dominance is lost. Needle chlorosis and necrosis appear and proceed in sprouts of male sexualization. The tree top including the female generative organs does not show degradation symptoms during about 30 years and produces seed cones. Processes of degradation in male generative zone greatly influence on fir tree pollen. Pollen viability of fir trees varied from year to year in different trees but always pollen quality of trees growing in the Khamar-Daban Mts in the air pollution zone was more poor in comparison with the pollen of trees at die Baikal Lake shore. Tree pollen growing in the Khamar-Daban Mts germinates in vitro but pollen tubes are formed short and not viable. Seed quality of fir trees is very low, A lot of seeds are sterile. Empty seeds prevail. The formation of empty seeds was caused by the low pollen germination in ovules and as a whole absence of pollen in ovules. The high sterility of generative organs and especially of Abies sibirica pollen can limit gametic selection and decrease fir diversity in forest ecosystems near Baikal Lake.

Similar patterns of change in stemwood calcium concentration in red spruce and Siberian fir

Аннотация: Changes in stemwood calcium concentration ([Ca]) for the last 120 years occurred in a common pattern for two sample collections of red spruce (n=33 and 20) from the northeastern United States and for one sample collection of Siberian fir (n=20) from southcentral Siberia, Russia. The [Ca] was measured for wood formed during the periods 1871-90, 1891-1910, 1911-30, 1931-50, 1951-70 and 1971-90. For each core, the relative increase or decrease in [Ca] for adjacent periods of wood formation was recorded. The relative frequency of positive change in [Ca] for each period of wood formation was calculated for the three sample collections. Previous research indicated that under equilibrium conditions, [Ca] in stemwood tended to decrease in more recently formed wood, due to declining numbers of Ca binding sites. Consequently, we expected a low frequency of positive changes in [Ca] in successively formed wood. Consistent with expectation, the relative frequency of positive change from the preceding period to the periods 1891-1910, 1911-30, 1931-50, and 1971-90 were low. Contrary to expectation, the frequency of positive increases in [Ca] more than doubled in 1951-70 compared to 1931-50. The frequency of positive increases in the 1951-70 period relative to the preceding period was 48%, significantly greater than all other periods (P less than or equal to 0.01). The frequencies of positive increases for all other periods were not significantly different from each other (overall mean = 21%, SD = 7). This anomaly in the frequency of positive change in [Ca] in wood formed in 1951-70 relative to wood formed in 1931-50 indicated a perturbation in the ion exchange chemistry of stemwood in two widely separated parts of the northern coniferous forest. This anomaly could be due to external or internal factors. Changes in sap chemistry that affected stemwood chemistry could have been due to changes in the rooting zone. Such changes in rooting zone chemistry could result from the atmospheric deposition of ionic pollutants. Other external factors that could cause the observed anomaly include unusual climatic periods or environmental disturbances such as logging or fire. Internal factors that might produce an anomalously high frequency of positive change of [Ca] include heartwood formation, stemwood infection and a hypersensitive response of the tree against infection.

Аннотация: Water solutions of fluorine and sulfur-containing salts of sodium-NaF, Na(2)SO(3), and NaF + Na(2)SO(3) (30, 150, and 300 MPC, respectively)-and salts of heavy metals-(Cu(NO(3))(2) center dot 3H(2)O, NiSO(4), and Pb(NO(3))(2) (10, 25, and 50 MPC, respectively)-were applied as pollutants to dark gray forest soils of experimental plots (1 m(2)) in Siberian larch (Larix sibirica Ledeb.) plantations once per growing period. The soil samples for the determination of the microbial biomass, respiration, and enzymatic activity (urease, protease, invertase, and catalase) were taken from the mineral soil layer (0-5 cm) at the beginning of the growing seasons before the application of the pollutants then in 14- to 18-day intervals every month. The fluorine and sulfur-containing compounds applied activated the respiration, lowered the enzymatic activity of the microorganisms, and decreased the microbial biomass by 1.3-2.2 times in the soils of the test plots as compared to the control one. The single application of Cu, Ni, and Pb increased the microbial biomass, while the changes in the basal respiration were compatible with its natural variability. Two months after the beginning of the experiment, all the parameters characterizing the functioning of the soil microbocenoses were restored.

Аннотация: Siberian peat bog are the largest in the world. Collecting of data on contaminating elements in Siberian peat deposits is important because no quantitative information has been available till recently. As a rule, the distribution of the concentrations of elements over the vertical profile of the stratigraphic column is used to study the evolution of pollutants in the environment. Using neutron activation analysis the concentrations of nearly 33 elements in 23 layers of peat deposits were determined. The thickness of the deposit is 8.4 m. The results provide a possibility for studying the geochemical aspects of the peat bog genesis down to 10000 years ago.

Аннотация: Studies of microsporogenesis in the Siberian larch growing in Krasnoyarsk and its suburbs have shown that meiosis starts in October. Microsporocytes winter at prophase I (leptoneme, diploneme). Reduction divisions in male generative buds are resumed and terminated in spring, in March. However, in the case of thaws during the autumn-winter period, meiotic division proceeds in the larch buds and this leads to the formation of degrading tetrads and pollen. Hence, the organic quiescence is absent in the larch in winter. It was shown that in the larch growing in the city, meiosis proceed more asynchronously than in the background tree stands. An increase of chromosomal aberrations during the reduction division was noted under the conditions of technogenic pollution.

Аннотация: As are other parts of the earth, arctic and subarctic territories are influenced by global, regional, and local air pollution. In Europe, the greatest load of airborne contaminants is observed in terrestrial ecosystems of the Kola Peninsula; in Asia, the greatest load is found in ecosystems of the Taimyr Peninsula, where large copper-nickel smelters are functioning. The studies described here for these regions encompassed local and regional deposition of pollutants (mainly sulfates and trace metals); changes in the composition, structure, productivity, and status of forest vegetation; morphological reactions of plant species and their regenerative activity; reforestation processes; successions; element composition of plants and soils; and biological activity of soils. The key findings of long-term studies are as follows. First, the symptoms of plant damage by air and soil pollutants in arctic and temperate zones are the same. Second, plants weakened by natural stresses have lower thresholds of sensitivity to airborn pollutants. Third, rapid destruction of northern plant communities by pollutants is often connected with a wide distribution of sensitive species (e.g., lichens) and previously weakened plants. Fourth, the specific structure of far northern forest and tundra ecosystems (in particular, open canopy and/or thin photosynthetic layer) and the severe climate produce some peculiarities in plant damage, namely (1) a large difference in the rate and intensity of damage to upper and lower parts of plants if the green parts are above or under snow in the winter, (2) simultaneous damage of different parts of stands that are above snow cover, and (3) an increase in the krummholz effect (stunted, low-lying branches) for evergreen coniferous trees. These findings were obtained for conditions of evident airborne contamination. The impact of low level regional pollutants on arctic and subartic vegetation is not sufficiently understood.

Аннотация: As are other parts of the earth, arctic and subarctic territories are influenced by global, regional, and local air pollution. In Europe, the greatest load of airborne contaminants is observed in terrestrial ecosystems of the Kola Peninsula; in Asia, the greatest load is found in ecosystems of the Taimyr Peninsula, where large copper-nickel smelters are functioning. The studies described here for these regions encompassed local and regional deposition of pollutants (mainly sulfates and trace metals); changes in the composition, structure, productivity, and status of forest vegetation; morphological reactions of plant species and their regenerative activity; reforestation processes; successions; element composition of plants and soils; and biological activity of soils. The key findings of long-term studies are as follows. First, the symptoms of plant damage by air and soil pollutants in arctic and temperate zones are the same. Second, plants weakened by natural stresses have lower thresholds of sensitivity to airborn pollutants. Third, rapid destruction of northern plant communities by pollutants is often connected with a wide distribution of sensitive species (e.g., lichens) and previously weakened plants. Fourth, the specific structure of far northern forest and tundra ecosystems (in particular, open canopy and/or thin photosynthetic layer) and the severe climate produce some peculiarities in plant damage, namely (1) a large difference in the rate and intensity of damage to upper and lower parts of plants if the green parts are above or under snow in the winter, (2) simultaneous damage of different parts of stands that are above snow cover, and (3) an increase in the krummholz effect (stunted, low-lying branches) for evergreen coniferous trees. These findings were obtained for conditions of evident airborne contamination. The impact of low level regional pollutants on arctic and subartic vegetation is not sufficiently understood.

Technogenic disturbance of pretundra forests in Noril'sk Valley
/ V. I. Kharuk [et al.] // Russian Journal of Ecology. - 1996. - Vol. 27, Is. 6. - P406-410
. - ISSN 1067-4136
Аннотация: The decline of pretundra forests at the north of Krasnoyarsk krai induced by emissions from Noril'sk Metallurgical Complex (containing SO2, NOx, and heavy metals) was investigated. Permanent test plots were situated according to a pollution gradient. The vital status of the forests was estimated and the amount of pollutants in leaves or needles, forest litter, and soil was determined. Sulfur content was found to vary from 30 to 500 kg/ha in the upper 0-2 cm layer and from 250 to 1300 kg/ha in the 0-20 cm layer. At distances of up to 40 km from the pollution source, the concentrations of heavy metals (Cu, Ni, and Co) in the upper 0-10 cm soil layer exceeded the background level by a factor of 10-1000. The sensitivity of tree species to pollutants decreases along the range larch-spruce-birchwillow. The zone of damaged forests spreads up to 200 km from emission sources along prevailing wind directions. At a distance of up to 80-100 km, the forests are dead.

Satellite data analysis of pollution-induced subtundra forest decline
/ V. I. Kharuk [et al.] // Earth Observation and Remote Sensing. - 1996. - Vol. 13, Is. 4. - P631-640
. - ISSN 1024-5251
Аннотация: The condition of the subtundra forests in the area affected by emissions from the Noril'sk mining and smelting plant was studied using images from the 'Meteor-Priroda' satellite and data from ground studies. A significant rate of increase in the damage to tree stocks from the end of the 1970s to the beginning of the 1980s was revealed, which was caused by the rise in SO2 emissions. At present, the area of forest decline extends to a distance of up to 200 km in the direction of the prevailing drift of pollutants, in up to 80-100 km of which, the trees have died.

Аннотация: Application of polarization characteristics of reflected radiation to indicate the water stress of plants and extent of their pollution by industrial dust is studied. Experiments were carried out under field conditions. The objects measured were the leaves and shoots of woody and agricultural plants. The measurements were carried out at the wavelengths of 1.75 ?m and 2.2 ?m, at the Brewster angle. The fact that the degree of polarization of reflected light can serve to diagnose 5-10% water loss by the foliage is established; the effect is due to altered spatial orientation of the foliage in the crown owing to water stress. Pollution of foliage by industrial dust is accompanied by a decrease in the degree of polarization of the reflected radiation: the model experiments demonstrated the possibility of recording pollution not more than 0.03 ton / h. The effect is based on the difference between the values of degree of polarization of pollutants and the foliage. В© 1990.

Аннотация: The study was devoted to investigation of the contents of radionuclides and of 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. The samples were collected in the area subjected to radioactive impact of the Mining-and-Chemical Combine (MCC) at Zheleznogorsk and in the control area, upstream of the MCC. The investigations shown that elodea biomass in the area affected by MCC operation contained a long inventory of artificial radionuclides typical for the MCC discharges. The upstream of the MCC, in the control sampling area, 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 microGy/d) and the main contribution info the dose is made by natural radionuclides. At the MCC discharge site (the village of Atamanovo) and at the downstream of it, the total dose rate increases almost an order of magnitude, reaching its maximal values--72 microGy/d for elodea shoots and 58 microGy/d for its roots. Cytogenetic investigations of elodea roots shown that at the MCC discharge site (the village of Atamanovo) and at downstream of it the occurrence of chromosomal aberrations in ana-telophase and in 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.

Аннотация: Species sensitivity distributions (SSDs) are increasingly used to analyze toxicity data but have been criticized for a lack of consistency in data inputs, lack of relevance to the real environment, and a lack of transparency in implementation. This paper shows how the Bayesian approach addresses concerns arising from frequentist SSD estimation. Bayesian methodologies are used to estimate SSDs and compare results obtained with time-dependent (LC50) and time-independent (predicted no observed effect concentration) endpoints for the insecticide chlorpyrifos. Uncertainty in the estimation of each SSD is obtained either in the form of a pointwise percentile confidence interval computed by bootstrap regression or an associated credible interval. We demonstrate that uncertainty in SSD estimation can be reduced by applying a Bayesian approach that incorporates expert knowledge and that use of Bayesian methodology permits estimation of an SSD that is more robust to variations in data. The results suggest that even with sparse data sets theoretical criticisms of the SSD approach can be overcome. В© 2006 American Chemical Society.

Аннотация: The content of pollutants in snow samples and their composition have been determined. The quantitative indicators of the content of nickel, copper, and other heavy metals and sulfur are used to assess the nature of spatial pollution of snow cover in the impact zone of enterprises in the Norilsk Industrial Area (NIA). A map of distribution of heavy metals and sulfur in the region is compiled. It is established that the largest part of pollutants entering the atmosphere in the form of dust was deposited on the underlying surface near sources of industrial emissions (up to 7 km from them). The pollutants entering the atmosphere in the form aerosols and gases are transported over considerable distances. A greater concentration of water-soluble forms of sulfur when compared with the background are marked at a distance of more than 400 km. Calculations show that only 2% of all sulfur emissions are deposited within a radius of 250 km and the remaining portion of sulfur is incorporated into the global geochemical cycles.

Die-off dynamics of Siberian larch under the impact of pollutants emitted by Norilsk enterprises

Аннотация: The radial growth of Siberian larch under the impact of pollutants emitted by enterprises of Norilsk has been analyzed to reconstruct the die-off dynamics of larch stands located along the Rybnaya River, along the main direction of pollutant air transport. Dendrochronological cross dating is used to detect the year of die off of 268 trees growing in 4 sites located 22, 45, 68, and 85 km from Norilsk. The death of individual trees in the sites closest to Norilsk was recorded immediately after the first enterprises started to operate in the early 1940s. The mass mortality of the trees started in the 1960s due to the operation of new smelters and the consequent increase in pollutant emissions. The complete destruction of the stands (100% die off of larch trees) occurred in the 1970s. At the most distant site (85 km), the highest rate of larch death was observed between 1975 and 1980, and in 2004 only 23% of larch trees were alive. A comparative analysis of the tree-ring width of the studied trees testified to the decrease in tree radial growth at the period before the complete degradation of stands. Unfavorable climatic conditions became an additional factor that enhanced the rate of tree die off due to the impact of pollutants. Although the increase in tree radial growth had been found in late 1990s to early 2000s at the site 85 km from Norilsk, the status of studied trees indicated that the area of completely degraded forest ecosystems might become larger under the present conditions.

Studying seasonal variations in carbonaceous aerosol particles in the atmosphere over central Siberia

Аннотация: The results of 2-year (2010-2012) measurements of the concentrations of organic carbon (OC) and elemental carbon (EC), which were taken at the Zotino Tall Tower Observatory (ZOTTO) Siberian background station (61A degrees N, 89A degrees E), are given. Despite the fact that this station is located far from populated areas and industrial zones, the concentrations of OC and EC in the atmosphere over boreal forests in central Siberia significantly exceed their background values. In winter and fall, high concentrations of atmospheric carbonaceous aerosol particles are caused by the long-range transport (similar to 1000 km) of air masses that accumulate pollutants from large cities located in both southern and southwestern regions of Siberia. In spring and summer, the pollution level is also high due to regional forest fires and agricultural burning in the steppe zone of western Siberia in the Russian-Kazakh border region. Background concentrations of carbonaceous aerosol particles were observed within relatively short time intervals whose total duration was no more than 20% of the entire observation period. In summer, variations in the background concentrations of OC closely correlated with air temperature, which implies that the biogenic sources of organic-particle formation are dominating.

Аннотация: The results of 2-year (2010-2012) measurements of the concentrations of organic carbon (OC) and elemental carbon (EC), which were taken at the Zotino Tall Tower Observatory (ZOTTO) Siberian background station (61A degrees N, 89A degrees E), are given. Despite the fact that this station is located far from populated areas and industrial zones, the concentrations of OC and EC in the atmosphere over boreal forests in central Siberia significantly exceed their background values. In winter and fall, high concentrations of atmospheric carbonaceous aerosol particles are caused by the long-range transport (similar to 1000 km) of air masses that accumulate pollutants from large cities located in both southern and southwestern regions of Siberia. In spring and summer, the pollution level is also high due to regional forest fires and agricultural burning in the steppe zone of western Siberia in the Russian-Kazakh border region. Background concentrations of carbonaceous aerosol particles were observed within relatively short time intervals whose total duration was no more than 20% of the entire observation period. In summer, variations in the background concentrations of OC closely correlated with air temperature, which implies that the biogenic sources of organic-particle formation are dominating.

Аннотация: Summer 2012 was one of the extreme wildfire years in Siberia. At the surface air monitoring station "ZOTTO" (60°48'N, 89°21'E, 114 m a.s.l.) in Central Siberia we observed biomass burning (BB) influence on the ongoing atmospheric measurements within more than 50 % of the time in June-July 2012 that indicates a 30 times greater wildfire signal compared to previously reported ordinary biomass burning signature for the study area. While previous studies thoroughly estimated a relative input of BB into aerosol composition (i.e. size distribution, physical and optical parameters etc.) at ZOTTO, in this paper we characterize the source apportionment of the smoke aerosols with molecular tracer techniques from large-scale wildfires occurred in 2012 in the two prevailing types of Central Siberian ecosystems: complexes of pine forests and bogs and dark coniferous forests. Wildfires in the selected ecosystems are highly differed by their combustion phase (flaming/smoldering), the type of fire (crown/ground), biomass fuel, and nature of soil that greatly determines the smoke particle composition. Anhydrosugars (levoglucosan and its isomers) and lignin phenols taken as indicators of the sources and the state of particulate matter (PM) inputs in the specific fire plumes were used as powerful tools to compare wildfires in different environmental conditions and follow the role and contribution of different sources of terrestrial organic matter in the transport of BB pollutants into the pristine atmosphere of boreal zone in Central Siberia. © Published under licence by IOP Publishing Ltd.
