The study was carried out on the survival of Escherichia coli and Aeromonas hydrophila in samples of mineral waters. Enumeration of the bacteria was performed by spread inoculation of samples (0.1 cm³) over the surface of selected media in Petri plates. Twenty bottles (four bottles of each of the five brands) of non-carbonated mineral waters with different levels of dissolved solids and organic content were chosen to study every strain. Ten bottles were stored at 4°C, the other ten were kept at 22°C. Half of the samples of mineral water was filtered, the remaining water was unfiltered. The resulting growth curves depended on the time of storage. The number of E. coli increased during the first two weeks (except the seventh day) and decreased during the next days. E. coli was detected in 70% of samples of water after 182 days. The number of A. hydrophila decreased during the first three days, increased on the seventh day and decreased during the next days. A. hydrophila was detected in 15% of the samples of water after 182 days. The temperature of storage was inessential for growth. The most important factors were the brand and the filtering or unfiltering of water. The highest numbers of the bacteria analysed were detected in filtered water, irrespective of the water brand and temperature of storage.

The study aimed at application of a high performance liquid chromatography (HPLC) with UV detector for selenium speciation in samples of mineral and well waters in Poland. Basic solutions 1000 μg/l SeO3 2- and SeO4 2- were prepared by dissolving 2.190 g of reagent Na2SeO3 and 2.393 g Na2SeO4 in 1000 ml of deionised water, respectively. Recent standards SeO3 2- and SeO4 2- (single or mixed) were prepared daily. Chromatographic separations were obtained on a column with reversed phase of C18, 250*4 mm, 5 μm ODS. As mobile phase mixture of 5 mmol/l phosphate tetrabutylammonium, 50/50 water/methanol at pH 3.4 was used. Flow rate of mobile phase was1 ml/min and detector was set on λ=210 nm. Injection volumes were 5 μl. The average concentration of Se(IV) was 4.10 μg/l and Se(VI) - 4.27 μg/l and Se(II) - 0.54 μg/l although the differences between water samples originating from various sources were relatively high. The developed method can be therefore recommended for determination of Se in samples of mineral water.

Background. Natural mineral waters may be an essential source of calcium, magnesium and other minerals. In bottled waters, minerals occur in an ionized form which is very well digestible. However, the concentration of minerals in underground waters (which constitute the material for the production of bottled waters) varies. In view of the above, the type of water consumed is essential. Objective. The aim of the study was to estimate the calcium and magnesium contents in products available on the market and to evaluate calcium and magnesium consumption with natural mineral water by different consumer groups with an assumed volume of the consumed product. Material and methods. These represented forty different brands of natural mineral available waters on Polish market. These waters were produced in Poland or other European countries. Among the studied products, about 30% of the waters were imported from Lithuania, Latvia, Czech Republic, France, Italy and Germany. The content of calcium and magnesium in mineral waters was determined using flame atomic absorption spectrometry in an acetylene-air flame. Further determinations were carried out using atomic absorption spectrometer - ICE 3000 SERIES-THERMO-England, equipped with a GLITE data station, background correction (a deuterium lamp) as well as other cathode lamps. Results. Over half of the analysed natural mineral waters were medium-mineralized. The natural mineral waters available on the market can be characterized by a varied content of calcium and magnesium and a high degree of product mineralization does not guarantee significant amounts of these components. Among the natural mineral waters available on the market, only a few feature the optimum calcium-magnesium proportion (2:1). Considering the mineralization degree of the studied products, it can be stated that the largest percentage of products with significant calcium and magnesium contents can be found in the high-mineralized water group. Conclusions. For some natural mineral waters, the consumption of 1 litre daily may ensure the recommended intake levels of calcium and magnesium in some consumer groups to a considerable degree. For 1-3 -year-old children it is recommended to consume less than 1 litre daily of natural mineral waters containing an excess of 700 mg of calcium and 80 mg of magnesium in 1 litre.

Background. A method of the classification of natural mineral and spring waters and maximum admissible concentration (MAC) levels of metals present in such types of waters are regulated by Commission Directive 2003/40/EC, Directive 2009/54/EC of the European Parliament and of the Council and Ordinance of Minister of Health of 30 March 2011 on the natural mineral waters, spring waters and potable waters. MAC of barium in natural mineral and spring waters was set at 1.0 mg/l, while World Health Organization determined the Ba guideline value in water intended for human consumption at the level of 0.7 mg/l. Objective. The aims of the study were: the determination of barium in natural mineral and spring waters (carbonated, noncarbonated and medium-carbonated waters) produced and bottled on the area of Poland, and assessment of human exposure to this metal presents in the above-mentioned types of waters. Material and method. The study concerning barium determinations in 23 types of bottled natural mineral waters and 15 types of bottled spring waters (bought in Polish retail outlets) was conducted in 2010. The analyses were performed by validated method of determination of barium in water based on inductively coupled plasma optical emission spectrometry, using modern internal quality control scheme. Results. Concentrations of barium determined in natural mineral and spring waters were in the ranges from 0.0136 mg/l to 1.12 mg/l and from 0.0044 mg/l to 0.43 mg/l, respectively. Only in the single case of natural mineral water the concentration of barium (1.12 mg/l), exceeded above-mentioned MAC for this metal, which is obligatory in Poland and the European Union - 1.0 mg/l. The long-term monitoring of barium concentration in another natural mineral water (2006 - 2010), in which incidental exceeding MAC was observed in 2006, was conducted. All measured barium concentrations in this water were lower than 1.0 mg/l and therefore, it is possible to state that the proper method of mixing waters taken from six independent groundwater intakes applied during production is actually used. The estimated Hazard Quotient indices were in the ranges: 0.0019 - 0.16 (natural mineral waters) and 0.00063 - 0.061 (natural spring waters), respectively. Conclusions. The natural mineral waters are usually characterized by higher Ba concentrations than those observed in the cases of natural spring waters. The presence of a high concentration of HCO3 - in such types of natural waters ensures the existence of Ba2+ in solution as Ba(HCO3)2, which is a highly soluble salt. Taking into account the concentrations of barium determined in above-mentioned waters and the available toxicological data for this metal no long-term risk for human health could be expected (estimated Hazard Quotient indices ≤ 0.16).

The study included water samples from 10 test points located in the northern parts of Sanok and Lesko counties. The following analytical methods have been used: AAS (FAAS, CVAAS, HGAAS), ICP-MS, ICPOES, Ion chromatography, Acid-base titration, argentometry, turbidimetry and also bacteriological tests. Two sources were identified as “natural mineral hard medium-mineralised waters” with low iron content. Four sulphide springs have been found. The Lesko source can be characterized as “a specific therapeutic sulphide water” with a content of divalent sulphur, determined iodometrically, above 1 mg · dm⁻³ and without any bacteriological concerns. Water from Lesko, apart from small amounts of metaboric and orthosilicic acid, is slightly alkaline with a strong negative ORP potential (–230 mV), which makes it healthy (an antioxidant that eliminates free radicals). In all waters the presence of heavy metals, arsenic, lithium, iron, manganese, alkali metals and alkaline earth metals has been indicated. The influence on the human body of analytically marked substances has been described.

The microbiological quality of five brands of carbonated and non-carbonated mineral water sold in Poland was studied. The study was carried out on the survival of heterotrophic bacteria at 22 and 37°C (pour plate technique) in the samples of mineral waters stored at 4 and 22°C. The one hundred ten bottles (twenty two bottles of each of the five brands) of carbonated and uncarbonated mineral waters with different levels of dissolved solids and organic content were chosen to microorganisms study. Ten bottles of mineral water were studied initially. Fifty bottles were stored at 4°C, the other fifty were kept at 22°C. The haemolysing bacteria in 1 cm³; E. coli, P. aeruginosa and A. hydrophila in 250 cm³ of mineral water were unidentifiable. Total viable count of heterotrophic bacteria at 22 and 37°C in 1 cm³ of mineral water was the highest respectively for brand T and for brands T and M; the lowest for brand Z. Initially, approximately 29% of 110 water samples (respectively 4% of carbonated and 55% of uncarbonated) had bacterial counts greater than Ministry of Health's standards, notwithstanding the number of water samples which doesn't perform requirements grew up to 47% (respectively 36% of carbonated and 58% of uncarbonated) when the time of TVC 37 and 22°C incubation was elongated from 1 and 3 days to 3 and 14 days respectively. The temperature of storage was inessential for the numbers of studied microorganisms. The most important factors were the brand, time of storage and the carbonating or non-carbonating of water. The highest numbers of the bacteria analysed were detected in non-carbonating water, irrespective of the water brand and temperature of storage.

Wprowadzenie. Biorąc pod uwagę asortyment naturalnych wód mineralnych i źródlanych oraz wód stołowych, a także ich stopień mineralizacji (od nisko do wysokozmineralizowanych) można przypuszczać, że będą one nabierały coraz większego znaczenia jako źródło składników mineralnych w codziennym żywieniu. Cel badań. Celem pracy była ocena wielkości spożycia wód butelkowanych oraz zawartych w nich wybranych składników mineralnych wśród młodzieży akademickiej. Materiał i metody. Badanie przeprowadzono wśród 2 grup studentek w wieku 18-26 lat Szkoły Głównej Gospodarstwa Wiejskiego (SGGW) oraz Uniwersytetu Kardynała Stefana Wyszyńskiego (UKSW), po 50 z każdej uczelni, w okresie od maja do października 2010 roku. Do oceny ilości pobieranej wody i spożycia składników mineralnych z wodami wykorzystano ankietę, w której kwestionariuszu zawarto pytania dotyczące zwyczajowego spożycia wód butelkowanych pod kątem ich rodzaju i ilości. Oceniano podaż wapnia, magnezu, sodu, potasu, krzemu, chloru i fluoru, jako głównych składników wód deklarowanych na etykietach opakowań. Wyniki. Prawie 40% badanych spożywało 4 szklanki wody dziennie, ok. 24% - 2 szklanki, ok. 24% - 3 szklanki, 11% - 1 szklankę, przy czym były to głównie wody nisko- i średniozmineralizowane. Przeciętne dzienne spożycie wapnia, magnezu sodu, potasu, chloru i fluoru w badanej populacji wynosiło odpowiednio: 64,1; 26,5; 14,3; 1,9; 5,4; i 0,1 mg/osobę. Pobranie krzemu było na poziomie 14, 4 mg/osobę/dzień. Spośród spożywanych z wodami butelkowanymi składników mineralnych największe znaczenie miały wapń i magnez (odpowiednio: 6% i 8% wartości referencyjnych). Wnioski. Wody butelkowane spożywane przez badaną populację nie stanowiły znaczącego źródła zaopatrzenia organizmu w składniki mineralne, ale mogą być ich cennym uzupełnieniem. Istnieje konieczność propagowania picia naturalnych wód mineralnych i źródlanych oraz stołowych jako źródła dobrze przyswajalnych składników mineralnych, zwłaszcza jeśli są to wody wysokozmineralizowane niskosodowe.

The fingerprinting concept that treats a chromatogram as a unique signal without peak identifying has been used in chromatographic comparative analysis. So far, no such approaches of ion chromatography have been published. Therefore, the aim of our work was to perform ion chromatographic analysis of five metals: Fe(III), Cu(II), Ni(II), Zn(II), and Mn(II) in 30 bottled mineral and spring waters available in the Polish market. The fingerprinting approach performed well and its main advantage is no need to perform the calibration procedure of each chromatographed ion. By investiging loadings, intercorrelated and orthogonal peaks were identified. We discuss the chemometric steps needed before comparison: smoothing, baseline removal, and warping.
