    Opis:
    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.

    Opis:
    Fountains are decorative elements that improve the attractiveness and visual qualities of urban environments. They can give refreshment to residents on a hot, sunny day. Despite the prohibitions on bathing in these facilities people often have contact with fountain water. It should be emphasized that poor quality of water from fountains can be dangerous for human health. This study was aimed at evaluating microbial contamination of water in Krakow fountains (fountain from Szczepański Square, fountain on the Groble Square, “Chopin” fountain near the philharmonic, “Stone” fountain on the Maria Magdalena Square and the fountain on the Main Market Square). Microbiological analyses were conducted to determine the total number of microorganisms at 36±2ºC after 48 hours (mesophilic bacteria) and the total number of microorganisms at 22±2ºC after 74 hours (psychrophilic bacteria). In addition, the coliform bacteria, Escherichia coli and Closridium perfringens were also examined. The results have shown a high degree of microbiological contaminants in the tested water samples. The lowest contamination of water was observed in the fountain on the Szczepański Square and in nozzle water from the fountain on the Groble Square. The highest numbers of bacteria were found in “Stone” fountain at the Maria Magdalena Square.

    Opis:
    Chitosan is a natural cationic polymer that dissolves in an acidic environment and forms gels. Its properties depend on the degree of deacetylation and molecular weight. It is a bioactive compound with antibacterial and film-forming properties that allow to increase the regenerative capacity of the skin. Moreover, it is biodegradable, biocompatible, non-toxic, and stable. In this research, chitosan was combined with mandelic and lactobionic acids which are characterized by biological activity and low toxicity. This combination not only has a positive effect on the chitosan solubility, but it also allows to obtain new biomaterials whose positive features of the base ingredients are enhanced by their synergistic effect. The obtained hydrogels were assessed regarding the interaction of chitosan and hydroxy acid molecules, and the stability of the resulting structures was examined. The research was performed by using rheological methods and IR spectroscopy. Chitosan hydrogels made with mandelic acid are characterized by higher viscosity values, as compared to hydrogels containing lactobionic acid. The samples of the obtained hydrogels stored for 7 days showed no signs of degradation and their viscosity values were constantly increasing, which proves the ongoing process of creating new bonds between hydroxy acid molecules and chitosan chains. After this time, the hydrogels with mandelic acid revealed higher viscosity values in comparison to hydrogels made with lactobionic acid. Based on the obtained IR spectra, the shifts of the characteristic chitosan bands as a result of interaction with the tested hydroxy acids were analyzed.
