The aim of the research project was to test the hypothesis that the white birch as hyperaccumulator of selected trace elements can be used in soil remedia-tion, that it acts as bioindicator in environmental studies and can be a useful spe-cies for planting to restrict migration of trace elements to the forest ecosystem with no adverse impact on its development and proper functioning. The research presented in this paper relied on a comparison of the mor-phometric parameters of assimilation apparatus in white birch (Betula pendula Roth.) growing in an isolated geomembranes soil, which has received two doses of trace elements in easily digestible forms. The results showed that the different levels of trace elements have the same impact on the state of assimilation apparatus birch. Given the prevalence of birch in Polish conditions, its good adoption to an environment with a strong human impact and low environmental requirements, this species may be suitable for planting in the form of biogeochemical barriers screening sources emitting trace elements (routes, dumps, landfills, industrial plants, sewage treatment plant).

The aim of study was to assess the effect of bottom sediments on the concentration of macronutrients (K, P, Na, Mg, Ca) and trace elements (Zn, Cd, Pb, Cr, Ni, Cu) in the plant test. The experimental design comprised 6 treatments: soil (control), soil + 5% of sediment, soil +10% of sediment, soil + 30% of sediment, soil + 50% of sediment and sediment (100%) in relation to the soil dry mass. The test plant - maize was harvested after 70 days of vegetation. Bottom sediment added to soil had a positive effect on maize biomass in the lowest dose, i.e. 5%. Higher doses of the sediment caused a reduction in maize yield. Bottom sediment positively affected concentration of nutrients: N, Mg, Na, K, Ca, Zn, Ni, Cu of maize shoots. However, the shoot biomass did not meet for fodder with respect to quality. Applied bottom sediment, has high content of sandy fractions, acid reaction and low concentration of organic carbon, nitrogen, phosphorus and potassium, can not be used as a fertilizer. Using bottom sediment from Narożniki reservoir in plant cultivation, one should take into consideration a necessity of application of supplementary NPK fertilization due to low concentration of these ...
Water is a significant source of macro- and microelements, necessary for the proper functioning of a human body. The purpose of this article was to analyze the quality of the selected bottled waters available on the Polish market in terms of the physico-chemical parameters (pH, conductivity, chloride ions, bromide ions), macroelements (sodium, potassium, calcium, magnesium) and trace elements (lead, nickel, antimony, arsenic). 17 brands of the bottled waters available on the Polish market were investigated within the study presented in the article (8 natural mineral waters, 6 spring waters and 3 therapeutic waters). The bottled waters, which were analyzed in the article, characterized with a large diversity of chemical composition. In two samples of therapeutic waters the permissible concentration of nickel was exceeded. ...
