Wpływ zanieczyszczenia gleby różnymi związkami rtęci na aktywność mikrobiologiczną gleby
(Wydawnictwa AGH, 2005) Florencka, Natalia; Chmiel, Maria
Presented paper concern studies on influence of soil contamination by mercury compounds $(HgCt_{2}$ $HgO$, $Hg(NO_{3})_{2})$ in five different doses (0,1. 0,5. 1,0. 5,0. 10,0 mg/kg) on number of vegetative and resting stages of mesophilic bacteria, Azotobacter genus, the number of Actinomycetes and microfungi. The results of laboratory investigations displayed the mean reduction of vegetative stages of mesophilic bacteria on sites with mercury oxide $(HgO)$ already in lowest dose - 0,1 mg/kg and the Actinomycetes number on sites with doses over 0,5 mg/kg $Hg(NO_{3})_{2}$. $HgCl_{2}$ (corrosive sublimate) was the most toxic compound to Azotobacter sp. Filamentous fungi were the most resistant group of soil microorganisms.

Zastosowanie algorytmów interpolacji i sztucznych sieci neuronowych do wyznaczania charakterystyki zawartości chromu w glebach
(Wydawnictwa AGH, 2005) Gruszczyński, Stanisław ; Urbański, Krzysztof
Various ways of approach, to determine the horizontal distribution trend (tendency) of Chromium (Cr) in soil, where is high pollution by this element are analysed. Polynominal regression algorithms (I, II, III degree polynominals), interpolation algorithms (TIN, Kriging, RST), and also artificial neural networks (MLP, CANFIS, RBF, GRNN, PNN, MDN) are applied. Data from field experiments, carried out in the area of Chemical Plant in Alwernia were used. The differences between several ways of approach are presented in a graphical form, and also in some remainders distribution statistics. The soil pollution spatial distribution examinations lead to following conclusion, that in the first place is the information precision determination, and also the limit of error, through the pollution evaluation acceptance, whereas in the second place is the indication or standing out the regularity connected with the imission effect mechanism. It seems that the chromium concentration in soils variation, noticed even on short distances, makes it difficult the acceptance of interpolation method, as a method of contamination distribution evaluation. On the other hand the considerable nonlinearity makes difficult the acceptance of regression model. In these circumstances, the possibility which is worth consideration, is the modelling with the application of neuron networks, that is also hybrid solution application (for instance MDN), which gives the possibility of Cr concentration in soils variation deeper analysis.

Zanieczyszczenie środowiska gruntowo-wodnego wielopierścieniowymi węglowodorami aromatycznymi w rejonie rafinerii
(Wydawnictwa AGH, 2005) Macuda, Jan; Solecki, Tadeusz
Oil refineries belong to industrial plants frequently polluting the ground-water environment with a variety of hydrocarbons. Ground and water contamination may be caused by leakages in the production installments and also during oil and oil-products storing. One of the most toxic ones are polycyclic aromatic hydrocarbons, produced in considerable quantities in the course of oil and crude oils processing. The quantitative state of the ground-water environment with respect to the polycyclic aromatics near one of the Polish oil refineries has been analyzed in this paper. Basing on the comparison of geochemical and hydrochemical results with threshold environmental standards, a conclusion was drawn that both grounds and underground waters are contaminated with polycyclic aromatics above the admissible values, qualifying them for remediation procedures to be applied.

Kształtowanie się wybranych właściwości inicjalnej gleby na zrekultywowanej w kierunku leśnym hałdzie górnictwa miedzi
(Wydawnictwa AGH, 2006) Wójcik, Jerzy ; Kowalik, Stanisław
Basic task of the biological stage of forest-directed reclamation of post-mining soilless areas is to speed up the growth of introduced plantations and stimulate soil-forming processes. During the reclamation, through technical and biological procedures the properties of initial soils are formed. Such properties have crucial influence on the value of the restored forest ecosystems. The goal of the carried out studies was to define the influence of four tree species on the properties of the initial soil, 8 years after the forestation of the waste heap of sterile rocks from the copper mining. In the paper the results referring to the accumulation of organic matter, organic carbon and nitrogen were presented as well as the selected physical and chemical properties of the studied initial soil. The obtained results indicate dynamic course of soil processes on the studied waste heap. This can be proved by the formation of characteristic for initial forest levels of accumulation already containing significant quantities of nitrogen-rich organic matter. In the layer 0-10 cm, the trend of favourable changes has appeared. This includes volume density, pH reaction and the content of nutrients. At the present stage of the development of initial soil the influence of the species composition of the forests could only be clearly seen in the accumulation of the organic matter and nitrogen.

Symptomy rozwoju procesu glebotwórczego pod młodymi zalesieniami rekultywacyjnymi na spągu wyrobiska Kopalni Piasku »Szczakowa«
(Wydawnictwa AGH, 2005) Kowalik, Stanisław; Wójcik, Jerzy
On the reclaimed floor of the old working of the Sand Mine »Szczakowa« the studies on chemical properties of soils under 10 years old larch (Larix europaea) and pine (Pinus silvestris) forest were carried out. Similar symptoms of the differentiation of the morphological picture of both initial soils (made of loose sand) were detected. Both under larch and pine about 1-cm thick layer of overburden humus were found as well as a very weakly marked initial humus level. Close to surface mineral layer (0-10 cm) of both soils were characterized with much higher than other content of organic C and N total. To the depth of 30 cm also big acidification of ground was found, compared to the initial state and at present, compared to deeper layers. Both soils are characterized by very Iow content of nutrients, small capacity of sorption complex, with a Iow degree of saturation with alkali. Despite very unfavourable properties of ground both larch and pine have high growth rate, which indicates a significant role of shallowly situated (0.7-0.9 m) layer of ground water.

Zanieczyszczenie chromem Jeziora Rożnowskiego
(Wydawnictwa AGH, 2005) Helios-Rybicka, Edeltrauda; Kuźniakowska, Magdalena; Gruszecka-Kosowska, Agnieszka
Roznowskie Lake is the reservoir of the accumulative contaminants, which are dumped into the waters of Dunajec and Poprad River. The aim of the researches was to define the level of contamination with chromium sediments and water in the Roznowskie Lake. This element was chosen for investigation, due to great spread of tannery works on this area of the river basin, that can be the source of the chromium. From the whole area of the lake it was taken 42 bottom sediment samples and 42 water samples with the suspended matter. Laboratory analyses showed, that there is very Iow concentration of the chromium in water and also in bottom sediments and suspended matter. Comparing the results with actual (valid) Polish Law connected with (related to) drinking waters, it can be said that with contamination of Cr, waters from Roznowskie Lake, belong to first class of cleanness. Sediments output by the processes of desludging of the water reservoirs, can be used for recultivation of soils, while the concentration of the Cr in none of the sediment samples overpass the permissible level of 200 mg/kg dry mass. Polish Legal Acts do not take under consideration defining the contamination level of pollutants in the suspended matter. According to German LAWA classification, constituents of the Roznowskie Lake with contamination of Cr, belong to the first class of cleanness (non polluted).

Pionowy rozkład zawartości rtęci w wybranych profilach glebowych w rejonie Alwernii
(Wydawnictwa AGH, 2006) Florencka, Natalia; Wojtanowicz, Piotr
In the article the studies referring to the definition of vertical distribution of mercury content in selected soil profiles were presented. Places of sampling were situated within the grounds used as meadows and forests in the vicinity of Chemical Plant »Alwernia« S.A. The concentration of mercury in the studied profiles was low and did not exceed 0.25 mg/kg. The decrease of the concentration with depth was observed both in meadows and forests. Maximum contents of mercury were observed in the layer of litter or in humus up to the depth of 5 cm. The correlation between the content of mercury and the quantity of organic substance was found, which confirms strong binding of this element in the organic or mineral-organic level.

Wpływ powodzi z 1997 roku na rozprzestrzenienie metali ciężkich w środowisku wód potoku Malinówka, w rejonie wysypiska odpadów komunalnych w Baryczy koło Krakowa
(Wydawnictwa AGH, 2005) Wardas-Lasoń, Marta; Budek, Leokadia; Kijas, Agnieszka; Rembalska, Romana
The presented paper contains the results of the study of water environment of Malinówka River in which catchment the municipal waste disposal site has been located. The subject of investigation was the distribution of heavy metals: Cd, Cr, Cu, Pb and Zn between water and bottom sediments. The interpretation of that distribution has been done on the base of physicochemical characteristics of water determined as pH, EC (electrical conductivity) and concentration of anions: $F^{-}$, $Cl^{-}$, $NO_{3}^{-}$, $SO_{4}^{2-}$ and $PO_{4}^{3-}$. It was found that the substandard concentrations show in water Pb, Cu and all anions. Concentration of Zn, Cd, Cr as well as pH are as high as those in water of the lst or 2nd class of purity. Concentrations of Zn, Pb and Cd in river sediments quality them as Iow contaminated sediments (1st class) while Cu and Cr concentration as intermediate contaminated sediments (2nd class). The results obtained were compared with those determined before the flood of 1997. It appeared that as a result of flood: increased pH and EC, considerably increased salinity, decreased heavy metal concentrations in both water and water sediments.

Wprowadzenie do oceny cyklu życia (LCA) - nowej techniki w ochronie środowiska
(Wydawnictwa AGH, 2006) Grzesik, Katarzyna
The aim of Life Cycle Assessment is studying the environmental impacts associated with a product, throughout the whole product's life, »from cradle to grave«, including raw material acquisition, raw material treatment, production process, transportation, distribution, usage, reuse, recycling, and ultimate waste disposal. LCA technique includes 4 phases, which are described in detail in this paper. These phases are: definition of goal and scope, life cycle inventory analysis of inputs and outputs (LCI), life cycle impact assessment (LCIA) and interpretation of analysis results in reference to goal of the study. LCA involves complex interactions between product (service) and the environment. The study should address the potential impact to human health, resource depletion and ecosystem health. The purpose of LCA is identifying the product or process, which is the least harmful to the environment, setting the priorities in product development and identifying the transfer of environmental impact from one media to another. The strategy of implementing in Poland the Integrated Product Policy was amended in February 2005. This strategy concentrates on minimizing the environmental impact of products in all phases of theirs life. This aim should be based on knowledge, delivered by widely and systematically used the life cycle assessment.

Teledetekcyjny monitoring środowiska
(Wydawnictwa AGH, 2005) Dworak, Tadeusz Zbigniew; Bonikowska, Maria
The paper presents some suggestions of an applictaion of remote sensing methods for the monitoring of envirnonment (natural and antropogenic). It contains also a short historical introduction to the problem of monitoring. As next it have been listed fundamental remote sensing methods (passive and active). Moreover, it is described principial differences between an in situ and remote sensing monitoring supported by the GPS and GIS technics. The neccesity of an application of complementar monitoring systems for more precise interpretation of obtained results of observations and measurements of environmental components is taken into consideration. Three fundamental, substantial components of environment have been defined such as: atmosphere, hydrosphere and litosphere together with biosphere. For the need of the remote sensing monitoring - especially for aerial photographs, satellite images and radiometrie observations - an idea of morfostructures of antropogenic and natural ecosystems have been introduced. The importance of using remote sensing methods in the environmental monitoring according to the accession of Poland to the European Union, at most was emphasized.
