Item type:Article, Access status: Open Access , Item type:Article, Access status: Open Access , Analiza zawartości metali ciężkich w nawarstwieniach historycznych Krakowa i ich rola wskaźnikowa w badaniach archeologicznych(Wydawnictwa AGH, 2009) Wardas-Lasoń, Marta; Such, JoannaThe archaeological post in Kraków has been examined, for several years, for the presence of heavy metals within the sequence sediment layers. Their concentration has been correlated with the presence of mineral - or anthropogenic phases, as well as artifacts and ecofacts. For the layers, distinguished by archaeologists, the geochemical photos have been done to trace the routs of contaminants' movement, and barriers preventing their migration. A strong anomaly of Pb and Cu concentration of anthropogenic origin, within mediaeval layers of Kraków Old Town, on the depth of several meters below the ground surface, caused an extraordinary situation for the scientists. It can be compared to the situation after introducing to the environment of the, so called, chemical marker. Due to this, the contaminant combining/releasing process may be observed, and even some, genetically conditioned, differences in stratigraphy of historical usage levels may be traced. The presence of a moat, surrounding the mediaeval defensive walls of Kraków, makes possible a reconstruction of the Kraków inhabitants' activity, associated with metal usage. It may be done by the investigation of variability in chemical and mineralogical composition, within profiles of water sediments.Item type:Article, Access status: Open Access , Results of the mineralogical investigation of bandage of Egyptian mummies(2009) Pawlikowski, Maciej ; Wardas-Lasoń, Marta; Strzelczyk, Jacek; Such, JoannaItem type:Article, Access status: Open Access , 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, RomanaThe 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.Item type:Article, Access status: Open Access , Georadar investigations and geochemical analysis in contemporary archeological studies(Wydawnictwa AGH, 2012) Łyskowski, Mikołaj; Wardas-Lasoń, MartaArcheological studies require a precise and interdisciplinary approach. Use of the noninvasive methods in urban area investigations is expected because they do not result in any changes in land architecture plans. Very good combination fulfilling such demands are geochemical analyses of: pH, Eh, conductivity and heavy metals concentrations in soils and the results of the ground penetrating radar method. These methods allow for a more precise selection of places of interest and can be also used for a more accurate calibration and better interpretation of subsequent results. Proposed methodology gives good final results thanks to complementarity of each method and can be used under variable conditions.Item type:Article, Access status: Open Access , Changes in the chemical composition of groundwater in Quaternary aquifer in Old Krakow, Poland (years 2002-2012)(Wydawnictwa AGH, 2013) Kasprzak, Agata; Motyka, Jacek; Wardas-Lasoń, MartaThe chemical composition of the Quaternary aquifer in Old Krakow was studied. Thirty water samples were collected from wells in the years 2002, 2009 and 2012. The water chemistry of groundwater in Old Krakow is associated mainly with anthropogenic impact. The water samples represent manly five-ion type: $Ca-Na-Cl-HCO_{3}-SO_{4}$, $Ca-Na-Cl-SO_{4}-HCO_{3}$ and $Ca-Na-HCO_{3}-SO_{4}-Cl$, the multi-ion water type is typical for polluted water. The results of groundwater studies in Krakow between 2002 and 2012 showed that the chemical composition of water is being constantly affected by ancient human activities. The predominance of chloride and nitrate ions can be connected with a large number of the contamination sources. The main sources of contamination are accumulations of the anthropogenic soils and the cultural deposits containing organic, communal waste and sewage which were gathered in the oldest parts of Krakow.Item type:Article, Access status: Open Access , Geochemiczne rozpoznanie zjawisk hydrotermalnej mineralizacji skał rejonu Pienińskiego Pasa Skałkowego(2012) Pawlikowski, Maciej ; Wardas-Lasoń, Marta; Košuth, MarianWykonano prace terenowe oraz badania mineralogiczno-petrograficzne i chemiczne żyłek występujących w skałach z otoczenia Pienińskiego Pasa Skałkowego, po stronie polskiej i słowackiej. Miały one na celu rozpoznanie obecnych w nich objawów procesów wtórnej mineralizacji skał oraz ich składu chemicznego, w szczególności obecności pierwiastków śladowych. Podjęto próbę wstępnego rozpoznania ewentualnych aureoli geochemicznych, zarówno w otoczeniu pienińskich andezytów, jak i Pienińskiego Pasa Skałkowego. Analizy chemiczne dowodzą, że w wypreparowanych ze skał składnikach mineralnych żyłek nastąpiło podkoncentrowanie metali, szczególnie Pb. Oznaczone zawartości Pb są 6-cio krotnie wyższe niż stwierdzane w skałach typu andezyt, czy nawet 10-cio krotnie wyższe niż występujące w piaskowcach. W rejonie Pienin wykazywano asocjacje geochemiczne pierwiastków, takich jak Fe, Cu, Pb, Zn, szczególnie w przeobrażonych hydrotermalnie skałach.
