[Determination of content of zinc and cooper in table and therapeutic mineral water].

Mineral table water and therapeutic water are good sources of macro- and microelement. Increase of consumption and variety of kinds of mineral water was the reason for undertaking this research. Contents of zinc and copper were determined in 13 kinds of mineral table water and in 12 kinds of therapeutic water by Atomic Absorption Spectrometry method (AAS) in Pye-Unicam SP0192 apparatus, after earlier concentration. Content of copper in mineral table water was from 0.4 microgram/l in "Krynica Zdrój" water to 11 micrograms/l in "Mazowszanka" water and in therapeutic water and from 1.7 micrograms/l to 22.6 micrograms/l. Content of zinc in mineral table water was from 7 micrograms/l to 640 micrograms/l and in therapeutic water was from 24 micrograms/l to 88 micrograms/l.

On the presence and identification of organic substances in drinking water and mineral waters.

The identification of organic substances present in mineral water has engaged the interest of hydrologists since the last century. Nowadays these organic substances, even if present in very small quantities, can usually be identified thanks to the remarkable progress made in various techniques of isolation, resolution, identification and dosage. The authors report the results achieved using a methodology of concentration by means of active coals and identification with thin-layer chromatography.

[Microbiological condition of bottled natural mineral waters, drinking water, as well as water from mineral springs].

We are now in the midst of a critical discussion on the microbiological quality of bottled natural mineral water, springwater, so-called "table water" and drinking water. "Still" waters have high colony counts after long storage, whereas in carbonated bottled products multiplication of oligocarbophilic microorganisms is suppressed by carbon dioxide. Opportunistic species are also found in bottled water. Present knowledge as to whether they are contaminants or part of autochthonous flora is insufficient. Highly colonised foodstuffs and opportunistic species may be hazardous for immunosuppressed patients. Hence, it is claimed that existing legal microbiological criteria for bottled water are inadequate. High colony counts in foodstuffs do not necessarily imply poor microbiological quality a priori. Detection of an opportunist species does not justify classifying a food item as hazardous. Microbiological criteria for bottled water which are laid down in the Directive for Mineral and Table Water of the German Food Legislation Act (LMBG) were established based on recommendations by international microbiologists for the normal not oversensitive consumer. For more sensitive groups of consumers, for example babies, more severe criteria were set up. Immunosuppressed patients are another sensitive group, demanding special hygienic requirements for their surroundings. If the risk of infections for immunosuppressed patients cannot be reduced by other means, it might be useful to establish microbiological criteria for bottled water and of course for other foodstuffs as well. However, such criteria cannot be adequately applied to food for normal consumption, since otherwise many foods would have to be regarded as hazardous and could not be marketed because of legal prescriptions.

[Recovered water mineralization technique].

The possibility to mineralize water by metering out concentrated salt solutions in the amounts necessary to bring it to within the potable water standards with intermediate exchange of chlorine ions for bicarbonate-ions has been demonstrated. The proposed technique ensures physiological quality and stability of recovered water mineralized with solutions of inorganic salts. Stability of concentrated salt solutions kept in metering syringes and potable water was evaluated. Organoleptic tests of resultant potable water were conducted.

[Legal requirements, quality criteria, therapeutic interest and dietetics of mineral waters: study of the case of the natural mineral water of Evian].

The considerable increase in mineral water sales as a daily drink reflects more or less the continued confidence in spa treatments, and this has caused the Public Authorities to set up very strict regulations in this field. We explain the main provisions of these regulations, compare mineral water with ordinary drinking water and complete this report with a study on the representative case of Evian Mineral water since it is the most exported water in the world. We emphasize the key points regarding the origin of the water which must be very well protected, its mineralization leading to its part played in dietetics and daily consumption, its use in spas and the research on its therapeutic effects, its bottling and the controls enabling its original high quality to be maintained. The conclusion reviews the motivations for the mineral water consumer: taste, quality, favorable effects on health. These motivations linked together have a varying importance according to the persons or situations involved. They result in precise requirements to be met by the producing companies in three fields: quality, advertising, credibility and scientific research.

[The potentials for the balneotherapy of obesity using arsenic-containing mineral water].

Arsenic mineral water from the Sinegorsk springs was tried in the treatment of experimental alimentary obesity in rat Wistar males and patients with exogenous-constitutional obesity. Body mass, blood lipids, hepatic neutral lipids, glucose-6-phosphate-dehydrogenase were measured. Arsenic mineral water proved able to reduce excessive body mass, correct blood lipid spectrum, normalize metabolic processes in the liver. Thus, arsenic mineral water can be used in balneotherapy of obesity.

Microbiological safety of natural mineral water.

Natural mineral water originates from groundwater, an oligotrophic ecosystem where the level of organic matter is low and of a very limited bioavailability. The bacterial populations that evolve in these ecosystems are heterotrophic and in starvation-survival state resulting from an insufficient amount of nutrients; for this reason they enter a viable but non-culturable state. After bottling, the number of viable counts increases rapidly, attaining 10(4)-10(5) colony-forming units ml(-1) within 3-7 days. These bacterial communities, identified by culture or with specific probes, are primarily aerobic, saprophytic, Gram-negative rods. Groundwater sources for natural mineral waters are selected such that they are not vulnerable to fecal contamination. Ecological data, especially the diversity and physiological properties of bacterial communities, are essential together with epidemiological studies in order to perform a risk analysis for natural mineral waters. On a continuing basis, the management of microbial risks has to rely on assessment of the heterotrophic plate count and, more specially, on detection of marker organisms, i.e. the classic fecal contamination indicators that have to be absent, and vulnerability indicators for which the occurrence should be as low as possible. It is also recommended to search regularly, but not routinely, for viral and protozoan pathogens.
