Thesis concerns archaeological layers located in the region Lokietkowy Grodek in Krakow. The main subject of diploma work is assessment of Cu and Pb contamination of sediments from the historical deposits and their influence on the present state. Analyzed layer lying at a depth of 2.0 to 6.5 m. On 27 samples measured physicochemical parameters: (pH, Eh, PEW), made separation of grain fractions, calculated the percentage of organic matter and humidity. Using the AAS method specified concentrations of copper and lead, and by ion chromatography determined inorganic anions. Analyses were conducted in aspect of mobilization and immobilization of Cu and Pb. Results obtained in the course of the study were presented in tables and figures, and in this form that they were subjected to analysis.

Badania zawartości Pb w glebach i w trawach Agrostis Capillaris i Brachypodium Silvaticum
(Wydawnictwa AGH, 2009) Kicińska, Alicja
The aim of the research was to define the amount of lead in soils and common grasses, which were taken form polluted areas, and look for a relations between the total concentration in soils, their bioavailable parts and concentrations in plants. Study of accumulation properties of grass <i>Agrostis capillaris</i> and <i>Brachypodium silvaticum</i>, which are growing in different nature abodes shown that they can be used as biomarkers of lead pollutions.

This work presents result of research content $Zn$ i $Pb$ in soils and sediments in Biała Przemsza valley. Samples were taken on Oct. 22, 2011 year in the Sławków. It was done five drilling (S I, S II, S III, S IV, S V) and taken 61 samples. The collected sediment measured temperature, pH, Eh and PEW. The content of water, organic matter and carbonates measured by weight method. For chosen samples was performed BCR sequential extraction. It served determine the potential mobility of $Zn$ and $Pb$ in the analyses samples. Studies have shown that the most mobile part of the fraction $Zn$ in sediments is 7 - 63%, in the soils of 7 - 38% and $Pb$ 3 - 70% of the sediment, and 6 - 62% of the soils. The highest absolute concentrations of metals in the most mobility form was found in soils closest to the river bed. As you move away from the trough of the show a downward trend.

Wydział Geologii, Geofizyki i Ochrony Środowiska
Celem pracy jest ocena stanu środowiska glebowego w pobliżu zakładu przemysłowego Stomil Sanok S.A. na terenie miasta Sanoka (Fig. 1). Praca skupia się na analizie zanieczyszczeń powyższego obszaru pod kątem zawartości węglowodorów ropopochodnych i metali ciężkich (Pb i Cd). Praca została napisana w oparciu m.in. o badania laboratoryjne wykonane w Katedrze Mineralogii Petrografii i Geochemii (wykonanie oznaczeń węglowodorów ropopochondych dokonał dr inż. Piotr Bożęcki). Zakres pracy obejmuje metodykę i analizę wyników uzyskanych za pomocą dwóch metod: fourierowskiej spektroskopii w podczerwieni (oznaczenie węglowodorów ropopochodnych) i atomowej spektrometrii absorpcyjnej (oznaczanie kadmu i ołowiu).

Work touches on the problem environmental pollution with trace metals in Gródek nad Dunajcem community. This is agriculture and touristic region, without the usual sources of pollution in the vicinity. . Assessment of the community are made based on the results of studies the concentration of metals (chromium, zinc, cadmium, copper, nickel, lead) in samples of soil, water and edible plants, as well as the results of studies soil and water acidity. Determined as the least polluted areas around the village Gródek nad Dunajcem. Small contamination was found with zinc and lead.
