Opis:: Migration and concentration of heavy metals in infiltration waters within unsaturated and saturated zones of a carbonate massif result from their mobility as well as anthropopression. The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn.

Opis:: A study was carried out on the leaf abscission zone from birch trees growing on polluted sites (two) and a non-polluted site (one). Samples for anatomical investigation were collected from six trees on each site, during three succeeding vegetation seasons. It was observed that in trees growing at the polluted sites: 1) maturation of the abscission zone was faster, 2) the protective layer was thinner and 3) the formation of leaf scar periderm was delayed in comparison with trees from the non-polluted site. The results obtained suggest that environmental pollution influences the formation of the abscission zone and the protection of the leaf scar.

Opis:: The authors explored the utilization of simulation models as a means to ensure environmental safety, using the industrial hub of Kemerovo as an illustrative example. The article analyzes the factors that have contributed to the deterioration of the environment in the region for decades. It has been established that in terms of the overall percentage distribution of emissions from stationary sources, energy enterprises (73.0%), chemical and petrochemical industries (4.7%), and black metallurgy enterprises (7.8%) are leading in the city of Kemerovo. Simulation modelling has shown that the cause of high concentrations of harmful substances in the atmosphere of Kemerovo is due to the negative factors of industrial and household activities and their impact on environmental safety. High correlation and sensitivity coefficients indicate a lack of new available technologies in the region's industry and transport that could prevent air pollution. The forecasting model has indicated a potential two, three or even greater increase in emissions. For example, in the long-term perspective, by 2063, manufacturing emissions could potentially increase by 35 times, leading to irreversible ecological consequences. Extreme pollution and depletion of natural resources could make living in this region impossible.

Opis:: Substances present in soils are of natural or anthropogenic origin. As a result of industrial activity, large quantities of potentially hazardous elements such as heavy metals are deposited in the environment. They may occur as unavailable (similar to the total form), or available for plants. The content of nickel in the soil from the former sanitary zone of the Głogów Copper Smelter does not exceed the Polish threshold values for industrial areas; however, its content may be influenced by other factors such as content of organic matter and soil reaction. In this article we present the results of the nickel pollution in the former sanitary zone of the Głogów Copper Smelter.
Obecne w glebie związki chemiczne mają pochodzenie naturalne lub antropogeniczne. Jako efekt działalności przemysłowej, do atmosfery emitowane są znaczne ilości zanieczyszczeń, w tym metali ciężkich. Zanieczyszczenia obecne w środowisku mogą być związane trwale z materiałem glebowym, część z nich jest jednak dostępna dla roślin. W artykule przedstawiono wyniki zanieczyszczenia niklem terenów strefy ochronnej Huty Miedzi Głogów. Badania wykazały, że zawartość niklu nie przekraczała wartości granicznych, wg obowiązujących w Polsce standardów dla gleb stref przemysłowych. Zawartość niklu może być jednak modyfikowana przez zawartość materii organicznej oraz pH.

Opis:: The intrinsic vulnerability of groundwater aquifers refers to their sensitivity to all contamination coming from soil surface irrespective of the nature of the polluting. In order to improve the protection of groundwater, there must be a reduction in the infiltration of contaminants towards the reservoir through the impacting factors determination of this phenomenon by means of research. There are collected models that include particular number of factors which allow the determination of a sign of groundwater vulnerability of all superficial pollutions. The goal of the study centers on ascertaining the state of vulnerability and the risk of groundwater pollution of the Collo region with a new proposed method by Kherici. Generally, assessment methods of vulnerability and the danger of groundwater pollution employ parametric systems with numerical quotation, cartographic superposition where the analytical methods are based on equations. In this study, we consider the combination of criteria dependent on natural factors (thickness of the unsaturated zone, geologic facies, degree of auto-purification) and the causes of groundwater vulnerability to man-made pollution (anthropogenic factors).
Podatność podziemnych poziomów wodonośnych odnosi się do ich wrażliwości na zanieczyszczenia pochodzące z powierzchni gleby, niezależnie od ich charakteru. Dla ochrony wód gruntowych konieczne jest ograniczenie infiltracji zanieczyszczeń po ustaleniu czynników wpływu metodami badawczymi. Istnieją modele obejmujące szereg czynników, które umożliwiają określenie podatności wód gruntowych na zanieczyszczenia powierzchniowe. Celem badań było określenie stanu podatności i ryzyka zanieczyszczenia wód gruntowych w regionie Collo za pomocą nowej metody zaproponowanej przez Kherici. W metodach oceny podatności i zagrożenia zanieczyszczeniem wód gruntowych stosowane są zwykle parametryczny system numeryczny i kartograficzne nałożenia, w których metody analityczne bazują na równaniach. W pracy rozważano kombinację kryteriów zależnych od czynników naturalnych (miąższość strefy nienasyconej, facje geologiczne i stopień samooczyszczenia) oraz przyczyny podatności wód gruntowych na zanieczyszczenia antropogeniczne.

Opis:: Danger of pollution of water areas of the Sea of Azov and the Kerch Strait from possible technogenic catastrophes is diagnosed as a result of comparison of wind power calculations and the current state of coast of the gulf. Ideas of a uniform West Temryuk stream of deposits are disproved. Three dynamic systems in the east and in the center of a coastal arch and the unidirectional alongshore stream of pollutants and energy in the western segment of the Temryuk gulf are revealed.

Opis:: When it comes to gas turbines, their main problem concerning pollutant emissions is represented by nitric oxides. Among other emissions, sulphur oxides being much reduced due to the use of liquid distilled and gas fuels with a low content of sulphur. Using water or steam injection became the favourite method during the '80s and especially the '90s since "dry" methods and catalytic reduction were both at the beginning of the development phase. Catalytic convertors have been used since the '80s and they are still used although the costs of renewing the catalyst are very high. In the last twenty years a gradual decrease has been registered on the limits of nitric oxides from 75 ppm to 25 ppm, and now the target is oriented towards the 9 ppm level. The evolution of burning technologies of combustion makes it possible to control the level of production of nitric oxides even from the source without being necessary to use "humid" methods. This, of course, opened the market for gas turbines because they can function even in areas with limited quality water reserves, such as maritime platforms and in the desert. In this paper, we are going to show that, although water injection is still used, "dry" control technologies of burning became favourite methods for the majority of users on the industrial power generators market. The great dependency between the creation of nitric oxides and the temperature reveals the effect of direct water or steam injection on reducing nitric oxides. Recent research showed that a reduction up to 85% of nitric oxides may be obtained by using the water or steam injection all together with the improvement of aerodynamic character of the burning room.

Opis:: Four metals (Cu, Zn, Pb and Cd) were assayed in soils within the impact zone of the Miasteczko Slaskie Zinc Smelter (southern Poland). The investigated area is afforested and has been subjected for a long time to intensive deposition of metal-bearing dusts. Soil pHKCl varied broadly from very acidic (pHKCl = 3.4) to slightly alkaline (pHKCl = 7.2). Organic carbon (Corg) content fluctuated within a large range, i.e., 5.5 - 66.4 g kg-1, whereas the cation exchange capacity (CEC) was in most cases markedly low (from 1.4 to 5.9 cmol(+)kg-1), with exception for two sites (C and D) exhibiting values of 26.8 and 15.1 cmol(+)kg-1, respectively. Total Zn, Pb and Cd contents exceeded manifold their respective levels in the Earth crust (reference value - RV)) as well as those suggested as background levels for Poland (BLP). The assessment of the contamination of soils by these metals was undertaken on the basis of geoaccumulation indices (lgeo), contamination factors Cl and degrees of contamination (Cdeg). The overall metal contamination represented practically two classes: low contamination for Cu; considerable to extreme contamination (in ascending order) for Zn, Cd, and Pb. The contribution (BLP-based assessment) of each metal to the degree of contamination index varied from 2.14 % (for Cu), via 26.33% (for Zn) to quite equally for Cd and Pb, both representing 35.22% and 36.32, respectively. It is worth pointing out that copper was the sole metal to threaten the least (Figure 1) the soils of the investigated ecosystem.
