Summary Samples of metallurgical dusts and fly ashes from coal power plants and iron works in Upper Silesia as well as soil profiles
in the close vicinity of these plants and in Ojcow National Park (ca. 25 km east of the industrial area) have been studied
magnetically and mineralogically. The metallurgical dusts and fly ashes are highly enriched in ferromagnetic minerals. The
topsoils from profiles collected near the plants have very high values of magnetic susceptibility while susceptibility in
the fermentation and humic subhorizons in soil profiles from Ojcow National Park is considerably increased. The magnetic properties
of the metallurgical dusts and fly ashes such as frequency dependence of susceptibility, saturation remanence or coercivity
are similar to those observed in the top horizons of the soils. They are mostly related to the occurrence of large (multidomain)
grains of non-stoichiometric magnetite ranging from 1 to 20 μm. The similarity of the magnetic particles in the soils is taken
as evidence of an anthropogenic origin. They are responsible for the high soil susceptibilities in Upper Silesia and in adjacent
areas. Some of the magnetic particles carry substantial quantitities of trace elements such as Pb, Ni, Zn and Cu. Field and
laboratory susceptibility measurements can therefore be used as a simple and costeffective method of detecting the presence
of heavy metals in the soils of this area. 相似文献

Thirteen polycyclic aromatic hydrocarbons (PAH) compounds have been identified in spa waters of 10 different health sources in the Sudetes region. In some of the waters the amount of PAH exceed the standard limits set up by the World Health Organization (WHO). The results obtained show that PAH can be a sensitive indicator of pollution of underground water. 相似文献

Recent work concerning the investigation of vertical movements in the Carpatho-Balkan Region is reported, based on the “Explanatory Text to the Map of Recent Vertical Movements in the Carpatho-Balkan Region”.For this investigation, the following countries supplied information: Bulgaria, Czechoslovakia, GDR, Hungary, Poland, Romania, USSR, Austria, and Italy. The activities were coordinated by the Hungarian Geodetic Service. Hungary undertook the task of collecting the data, their preparation for adjustment, and the adjustment of the investigation network, as well as the compilation and publication of the map of vertical movement. The authors present the algorithm of the rigorous adjustment: the height differences of the second leveling have been adjusted jointly with the velocities derived from the first and second levelings.In this paper the applied geodetic and oceanographic data, as well as the main character of the investigation network are presented. The interpretation of the adjustment is outlined.The map of Recent Vertical Movements in the Carpatho-Balkan Region (CBR) is printed at the scale of 1:1,000,000.In general, it is claimed that due to the new methods of investigation, the new CBR map of vertical movements provides a better tool to help with further investigations. 相似文献

Formaldehyde levels were determined in various forms of atmospheric precipitation (rain, snow, road and roof runoff, throughfall) and deposition (rime, hoarfrost, dew) collected over twelve months at various locations in two large urban agglomerations and along two highways. HCHO was found in 303 of 500 samples analyzed, with concentrations ranging from 0.05 to 10.7 mg/dm3. The results confirmed the significant effect of vehicular traffic on formaldehyde levels in various forms of wet deposition. Correlations of formaldehyde levels with other parameters commonly monitored in precipitation and/or deposition were also examined. No correlation was found between HCHO levels and rain volume. On the other hand, positive correlations were found for hydrogen peroxide, non-sea-salt sulphate, nitrate, ammonia, and total organic carbon (TOC). In addition, the effect of selected meteorological parameters (temperature, wind speed, wind direction, rainfall) on the concentration of formaldehyde in various forms of precipitation and runoff (road runoff, roof runoff, throughfall) was studied. The only correlation found was that between HCHO concentration and daily rainfall. 相似文献

The paper discusses the impact of atmospheric circulation on the occurrence of various types of precipitation. A 146-year-long precipitation record from Kraków spanning the period 1863?C2008 was used alongside a calendar prepared by Nied?wied? (1981, 2009) describing circulation types covering the period 1873?C2008 and air masses and atmospheric fronts covering the period 1951?C2008 in southern Poland. The influence of atmospheric circulation on precipitation was measured using the frequency, conditional probability and average daily totals of precipitation. Circulation types, air masses and atmospheric fronts exerted influences on precipitation as a result of the seasonal variations of the thermal and moisture properties of air masses. The impact is best expressed by circulation types as these combine the aspect of cyclonicity/anticyclonicity with that of the direction of air advection, the two elements which determine the physical properties of the air. On average, liquid precipitation prevailed in all circulation types, except the Ea type in which snowfall dominated over liquid precipitation. Depending on the season, one of the three types of circulation, Wa, Wc and Bc, were shown to coincide with the greatest amount of liquid and thunderstorm precipitation. There was no single dominant circulation type for mixed precipitation or snowfall. In summer, the circulation types Nc, NEc, Cc and Bc were the most favourable to liquid and thunderstorm precipitation in terms of both probability and totals. In winter, snowfall was the most favoured by the Ec type. Frontal precipitation was twice as likely to occur as air mass precipitation, with the exception of snowfall which was predominantly an air mass type of precipitation in terms of probability, but its greatest totals were recorded on atmospheric fronts. 相似文献

Geological prognosis of zinc and lead potential resources for Triassic formations was carried out for the Olkusz district in the southeast part of Silesian-Cracow region. Known deposits, typical phenomena in surrounding rocks, and quantitative methods for metallic ores for the perspective region or formation were a basis for the models. Statistical analysis of zinc and lead distributions and their interpretation were used to distinguish between the populations of background, anomalies, and ore bodies. Estimated values of the thresholds in the Triassic formations, i.e., 0.5 (anomalies) and 1.1 (ore bodies) wt. % of Zn, and 0.3 and 0.7 wt. % of Pb, respectively, represent the natural limits of concentration for both metals. Similar values of the thresholds obtained by other authors for other districts indicate regional regularities of zinc and lead concentration in the Triassic formations in the whole Silesian-Cracow region. Using these threshold values, the perspective zones of metals concentration can be proposed in the poorly explored areas of this region. In known deposits, the natural limit of zinc used as a cut-off value increase the reserves by about 30–40%. 相似文献

Three of the methods available for measurement of suspended sediment concentration were chosen and tested in natural conditions. The equipment included sand traps, a radioisotopic probe and a long-action sampler (bathometer).The working conditions of the equipment were studied and the reliability of data obtained was analyzed. Sources of possible errors have been defined together with requirements for the techniques, and optimum technical parameters have been found. Averaging times, necessary with regard to the reliability of data, have also been determined for the measurements. Calibration and cross-calibration of the measuring devices was carried out. Technological requirements, advantages and areas of applicability are discussed for the techniques. Although they require some modifications, the techniques can already be used in measurements of concentration profiles. The data obtained, and partly shown in this paper, shed light on complex phenomena of sediment suspension. 相似文献

We present the results of an extensive study of the Tunguska Cosmic Body (TCB) origin on dynamical grounds. To identify the
TCB parent, or a plausible candidate, we applied the well-known concept of dynamical similarity whereby we have compared the
geocentric and heliocentric dynamical parameters of a selected set of the Near Earth Objects (NEOs) and TCB particles. First,
we made use the idea of Kresak by comparing geocentric coordinates of the TCB radiant with those of the NEOs. Second, we studied
the long-term dynamical evolution of all NEOs and TCB particles searching for similarities between their heliocentric orbits.
As a general result, we observed many more similar cases and a different pattern of the high orbital similarity among the
TCB particles and the asteroid orbits than we did for comets. 相似文献

Long-term variability of occurrence of precipitation forms in winter in Kraków, Poland 总被引:1,自引:0,他引:1

The paper discusses long-term change in snowfall, rainfall and mixed precipitation viewed in conjunction with air temperature and North Atlantic Oscillation (NAO) in winter (December–February). In the study of contemporary climate change and its effect on the hydrological cycle it is useful to focus on winter precipitation forms. A 146-year secular observation series from Kraków, spanning the period 1863–2008, was used to extract data on the number of days with precipitation and on precipitation amount broken down by form. Statistically significant trends were found in total and mixed precipitation, but not in snowfall and rainfall. The climate warming effect has contributed to a material decrease in the snowfall to total winter precipitation ratio during the second half of the 20th c. The highest impact of air temperature was found in the wintertime variation in number of days with snowfall while the NAO had a significant influence on the frequency and amount of both rainfall and snowfall. 相似文献
