Introduction. In the human skin exposed to ultraviolet (UV) radiation, melanogenesis occurs in two stages, accompanied by urinary excretion of Thormalen-positive melanogen (TPM). In Poland, no data are available on the course and intensity of melanogonesis in relation to UV exposure in an industrial region. Material and methods. The Thormalen test was used for the collected samples (N=136) as modified...
The objective of the research was to determine the effect of habitat type of selected species of trees on the nature of cooccurrence of Fe, Mn, Zn, Cu, Pb, Cd, Ni, Cr and Co. The presence of speciation forms of these metals was investigated, with reference to the species composition of tree stands in selected areas of the Tatra Mountain National Park (Chochołowska Valley, Strążyska Valley, Kościeliska...
Our research investigated the bioavailability of Pb, Cd, and Ni in the soil of Tatra Mountain National Park (Chochołowska Valley, Kościeliska Valley, Małej Łąki Valley, and Strążyska Valley). The content of Pb, Cd, and Ni was estimated using the ASA method with accuracy of 0.1 μg/g. Rudd's methodology was applied to estimate direct and indirect bioavailability of the metals in question. Ions of Pb...
The object of our study was to estimate Pb content in the legally-protected plant Hacquetia epipactis, as well as stinging nettle (Urtica dioica), in the nature reserves laid in the border zone between Poland and the Czech Republic. The following forms of Pb reserves in soil were determined for biotopes of these plants: pseudo- total content and speciation forms, as well as soluble and insoluble forms...
Certain species of mushrooms, owing to their capacity to accumulate some bioavailable heavy metals such as Cd and Pb, can contain several-fold higher amounts of metals than the soil (speciation forms) in which they grow. It seemed noteworthy to undertake studies concerning the content of bioavailable forms of metals contained in the soil of mushroom habitats. The field part of our study was performed...
Bioavailability of individual chemical forms of metals occurring in soil is a basic source of its accumulation in plants. Soils from a root layer collected from the stands of stinging nettle Urtica dioica L., reflect different habitat conditions in the area of Wisła, a town in southern Poland. The Bukowa, Czarne, Głębce, Jawornik, Kubalonka, Malinka, Kobyla, and Salmopol also were research subjects...
The mainly purpose of our study was to determine Ba in pharyngeal tonsils of children living in the influence of dust emission from power stations in the following regions in southern Poland: Jura Krakowsko-Częstochowska, Upper Silesia, and Krakow. The concept of investigation was based on the fact of high levels of Ba in suspended dust emitted by power stations (about 800 μg/g). Moreover, these children...
An osseous tissue represents a specific repository of many metals. Some of them are physiologically accumulated in the skeleton, while others remain in the bones as a result of exposure and can be the cause of pathological states. The aim of this study was to determine the occurrence and co-occurrence of As with trace elements in the femur head; analyzing their concentration in male and female femur...
