Analysis of selected physico-chemical parameters in bottled waters available on the Polish market

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.
