Determination of Trace Elements (Ag, B, Ge, Mo, Sn, W, Tl) in Reference Samples of Soils and Bottom Sediments by Atomic Emission Spectrometry: A Traceability and Fitness-for-Purpose Study     

Albina I. Kuznetsova  Olga V. Zarubina  Olga A. Sklyarova 《Geostandards and Geoanalytical Research》2007,31(3):251-259

Reference samples of soils from the Institute of Applied Physics, Irkutsk (RIAP), the Institute of Geochemistry, Irkutsk (IGI) and the United States Geological Survey, Reston (USGS) were analysed with the aim of determining Ag, B, Ge, Mo, Sn, Tl and W abundances by an atomic emission method with air-stabilised D.C. arc excitation. Two series of reference samples of soils and bottom sediments, GSS-1-8 and GSD-1-12 (IGGE), were used to ensure the traceability link for the analytical results. Traceability was also demonstrated through the comparison of measured results by AES and ICP-MS methods. It is shown that the reference samples GSS-1-8 and GSD-1-12 satisfied the "fitness-for-purpose" criterion (uncertainty U of the certified value should be one-third to one-tenth the magnitude of routine laboratory data uncertainty S (S/U > 3-10)) and can be applied for calibrating AES techniques.  相似文献

Ozone content over the Russian Federation in 2013     

A. M. Zvyagintsev  N. S. Ivanova  G. M. Kruchenitskii  I. N. Kuznetsova  V. A. Lapchenko 《Russian Meteorology and Hydrology》2014,39(2):132-136

The review is compiled on the basis of the results of the operation of the total ozone (TO) monitoring in the CIS and Baltic countries functioning in the operational regime at the Central Aerological Observatory (CAO). The monitoring system uses the data from the national network of M-124 filter ozonometers under the methodological supervision of the Main Geophysical Observatory. The quality of the functioning of the entire system is under operational control based on the observations obtained from the OMI satellite equipment (NASA, the United States). The basic TO observation data are generalized for each month of the fourth quarter of 2013, for the quarter as a whole, and for the whole year. Some results of regular observations of surface ozone content carried out in Moscow region and Crimea are also considered.  相似文献   

Observed and calculated variability of the particulate matter concentration in Moscow and in Zelenograd     

I. N. Kuznetsova  I. B. Konovalov  A. A. Glazkova  M. I. Nakhaev  R. B. Zaripov  E. A. Lezina  A. M. Zvyagintsev  M. Beekmann 《Russian Meteorology and Hydrology》2011,36(3):175-184

The results of a comparative analysis of temporal and spatial variations in the particulate matter (PM₁₀) concentration are under consideration; the information is obtained based on the measurement data from the Mosekomonitoring network of stations and results of calculations with the CHIMERE chemistry transport model adapted for the Russian central region. The intercomparison of measurement data obtained in summer 2007 and respective calculations showed that the model provided a satisfactory reproduction of the observed temporal variability of the daily mean PM₁₀ concentration (an averaged correlation coefficient is 0.8), but systematically underestimated the absolute values of the PM₁₀ concentration. It is shown that model data quality can be significantly improved due to a simple a priori correction of the model errors. Irregularities in the spatial distribution of the PM₁₀ concentration and their dependence on meteorological conditions were revealed. The reasons of the formation of episodes of a high PM₁₀ concentration are considered.  相似文献

Structural-typological characteristics and ecological potential of the Baikal region’s geosystems

We outline the methods and results of cartographic analysis and assessment the present state of a large region’s geosystems: their structural, functional and functional-value characteristics have been revealed. Drawing on the notion of epiformations, we determined the ecological potential of geosystems at the regional level for nature management purposes. A fragment of the typological general-purpose interpretation map “Ecological potential of the Baikal region’s geosystems” is presented.  相似文献   

Temporal variations of the interplanetary magnetic field at the Earth’s orbit and of the solar activity     

T. V. Kuznetsova  L. B. Tsirulnik 《Solar System Research》2006,40(4):331-336

This paper analyzes the time changes of the common oscillations of the spectra of the absolute value of the interplanetary magnetic field measured at the Earth’s orbit from 1964 to 1997 and of solar activity (the Wolf sunspot numbers). The frequency components of the spectra were determined using the method of nonlinear spectral analysis. Oscillations with common periods of T = 10.8, T = 8.8, and T = 3.73 years have been identified in the long-period part of the spectra, and their temporal variations are shown. We discuss the specific features of the spectral band in the short-period part of the spectra in the vicinity of the known periods of T ～ 1.3 years and T ～ 150 days that have been identified earlier in the solar data and in the solar wind parameters.  相似文献
