RESUMO A Região Metropolitana de Natal, no estado do Rio Grande do Norte, é detentora de grandes reservas de águas subterrâneas pertencentes ao aqüífero Dunas/Barreiras. Essas águas são utilizadas pela população para seu abastecimento e consumo industrial. Além disso, essas reservas possuem características de águas minerais, localizando-se principalmente nos municípios de Parnamirim e Macaíba na região sul e no município de Extremoz, na parte norte. Em contrapartida, o crescimento urbano acelerado da Grande Natal, associado com a falta de esgotamento sanitário e drenagem adequada, resultaram no aporte de carga contaminante originária, principalmente, de fossas e sumidouros domésticos em direção às águas do aqüífero. Este artigo tem como finalidade avaliar as concentrações de nitrato nas fontes de águas minerais, tomando-se como base a proximidade de poços contaminados por esses teores. Para isso, basicamente, se comparou dados que representavam concentrações de NO3- em águas minerais, com teores de nitrato pertencentes à poços de abastecimento público ou particulares da região circunvizinha a essas águas, ambos obtidos através dos projetos de Iniciação Científica desenvolvidos no CEFET-RN. As atividades que fizeram parte da realização do trabalho foram constituídas pela localização da área de estudo, seleção dos poços a serem analisados, análises laboratoriais do íon nitrato, tabulação e tratamento dos dados obtidos, além das considerações a respeito da qualidade das águas subterrâneas. Através dos resultados obtidos foi possível demonstrar a que níveis de concentração de nitrato estão os poços produtores de água mineral, destacando-se dois, dos dez selecionados, que apresentaram valores acima de 10 mg/L. PALAVRAS-CHAVE: água mineral, águas subterrâneas, aqüífero Dunas/Barreiras, contaminação, nitrato e Região Metropolitana de Natal. EVALUATION OF NITRATE CONCENTRATIONS ON MINERAL WATERS PRODUCED IN THE METROPOLITAN REGION OF NATAL ABSTRACT The Metropolitan Region of Natal, located in the state of the Rio Grande do Norte, is detainer of great reserves of groundwater from Dunas/Barreiras aquifer. These waters are used by the population for your supplying and industrial consumption; moreover these reserves possess mineral water characteristics, situated mainly in the cities of Parnamirim and Macaíba, in the south region, and in the city of Extremoz, in the part north. However, the fast urban growth of Natal, associate with the lack of sanitation and drainage, has caused the increase of contamination, mainly by the infiltration of septic tanks effluents in soil. The presented work has as main purpose the evaluation of nitrate concentrations in the mineral water sources, taking in consideration the proximity of wells already contaminated by nitrate. For this, data of nitrate concentrations in mineral waters were compared with those from wells of the public or private supplying from the surrounding region. The work comprised the localization of the study area, selection wells to collect samples, laboratory analyses of the ion nitrate, treatment of data, and the global evaluation of underground waters quality. Through the results was possible to demonstrate the levels of nitrate concentration on mineral water wells, including two with concentration higher than 10 mg/L. KEY WORDS: mineral water, underground waters, aquifer Dunas/Barreiras, contamination, nitrate and Metropolitan Region of Natal.

ABSTRACT A total of 103 isolates of Aeromonas spp. were obtained over a 3-year period from a natural mineral water and from surface streams located within the boundaries of the watershed of the natural mineral water wells and were typed by macrorestriction analysis of genomic DNA with XbaI and by pulsed-field gel electrophoresis. All Aeromonas caviae isolates from the natural mineral water belonged to the same clone, and an analogous clonal identity was found among Aeromonas hydrophila isolates. These two clones expressed no hemolytic or cytotoxic activities. Aeromonas isolates from surface waters showed high molecular heterogeneity and were not related to the clones found in the natural mineral water. The presence of aeromonads chronically found in the natural mineral water was a likely consequence of a localized development of a biofilm, with no exogenous contamination of the aquifer. Molecular fingerprinting of drinking water isolates is a useful tool in explaining possible reasons for bacterial occurrences.

Introduction. The fact itself that thermo-mineral waters and mud have healing effects has always attracted attention throughout the history to exploit, explore and study their benefit on the human body. Modern lifestyle and the speed of life endanger man?s psycho-physical health. This is why people more often return to old time proven values, the nature and natural health resorts. Objective. To establish hydro-geological conditions for the formation of mineral water and to summarize their balneological characteristics in spas, i.e., in rehabilitation centres of the Pannonian basin of the Republic of Serbia, where underground waters are still actively exploited for balneotherapy. Methods. By retrospective descriptive analysis, a recapitulation of hydro-geological conditions for the formation of mineral waters was made and their balneological characteristics were established in eight spas of the Pannonian basin. Results. The healing spas of the Pannonian basin are predominated by HCO3 (2.9 g/l - 4.6% milival), iodic (up to 6.5 mg/l), slightly alkaline (pH up to 8.1) thermal-mineral water (temperature up to 72?C, bounty to 36.6 l/s) with a significant content of Br (up to 8.1 mg/l), Fe (to 6.0 mg/l), metaboron (up to 60 mg/l) and metasilicon acid (up to 95 mg/l). They are used for external application, bathing and showering. Conclusion. Once the Pannonian Sea (the Paratethys), today a wide plain terrain is a tectonic depression of the lower Pannonian pont age with compact type aquifers. In the geological column of sedimentary rocks a large underground aquifer was formed with free water of high mineralization, high temperature and geothermal properties above the average in relation to the European hydrogeological standards. Therefore, the Pannonian basin can be rightly called a thermal valley with the predominance of sodium hydro-carbonate (alkaline) iodine healing water of enviable abundance and reserves.

Abstract Limnological features of two reservoirs were studied in dry (August 2013) and rainy (January 2014) periods to evaluate the water quality that supply the city of Guarulhos, southeast Brazil. Water samples were collected in three depths and the following characteristics were measured: alkalinity, dissolved O2, free and total CO2, HCO3, soluble reactive silica, dissolved and total nitrogen and phosphorus, and chlorophyll-a. Water transparency was also measured and temperature, pH and electric conductivity profiles were obtained. Great seasonal and low spatial variability of the water characteristics occurred in the reservoirs. High values of water transparency, free CO2 availability, and low of pH, soluble reactive silica and total and dissolved nutrients values were recorded at the dry period, and different conditions were found at the rainy season. The two reservoirs were characterized by low nutrients, chlorophyll-a and turbidity, and high transparency, these features being typical of oligotrophic systems. The two reservoirs still remain under low anthropogenic impact conditions, and are presently considered reference systems for the SPMR, São Paulo Metropolitan Region. The need for actions that will reduce the input of nutrients from the neighboring cities and the main tributaries of the hydrographic basin is emphasized to maintain the ecological quality of the reservoirs and their reference conditions among the SPRM reservoirs.

The article analyzes the efficiency of complex physiotherapy in combination with internal intake of medium-mineralized water “Essentuki № 17” in patients with cicatricial skin changes in the presence or absence of metabolic syndrome. It was found that internal mineral water intake supplementing physiotherapy effectively corrected carbohydrate and lipid metabolism disorders by reducing the insulin resistance index, which contributed to a greater regression of clinical manifestations of cicatricial skin changes in patients with metabolic syndrome. Meanwhile, in the absence of metabolic syndrome, the course intake of mineral water did not signifi cantly affect complex physiotherapy, although the index of insulin resistance and body weight of patients significantly decreased. It is suggested that, given the presence of nonspecifi c preventive potential of the course of drinking mineral waters intake, there is some theoretical and possibly practical interest in research on pre-course mineral water intake before performing cosmetic operations to accelerate the process of skin regeneration and the formation of scarring in a less pronounced form.

Relevance. The study of alternative non-drug methods of rehabilitation therapy is an important task in the preventive direction of rehabilitation medicine. An important role in rehabilitation measures to prevent relapse of nephrolithiasis is therapy with the use of balneological therapeutic factors. The purpose of the study is to increase the effectiveness of rehabilitation therapy in patients with chronic pyelonephritis with the use of Serebryaniy klyuch mineral water. Materials and research methods. The basis of the work is the analysis of data from examination and treatment of 48 patients with chronic pyelonephritis in the phase of latent inflammation. All patients included in the study were divided into 2 groups. Patients of the 1st group (n = 23) were prescribed antibacterial, antispasmodic, herbal medicine and drinking fresh water. In addition to standard therapy, patients of the 2nd main group (n = 25) were prescribed 300350 ml of Serebryaniy klyuch mineral water 3040 minutes before meals up to 2 liters per day at a temperature of 3940 C. Results. In patients of the 2nd group in 91.4% of cases, curation of the clinical signs of the disease was noted, pathogens were eliminated in 100% of patients. At the same time, normalization of cytokine homeostasis and humoral immunity was observed, which contributed to a decrease in interstitial edema and normalization of renal vascular tone. Conclusion. The internal intake of Serebryaniy klyuch mineral water in the rehabilitation therapy of patients with chronic pyelonephritis has a positive effect on the elimination of the clinical manifestations of the disease, increases the percentage of sterile urine culture, improves the basal blood flow in the kidneys, the immune status of patients, the cytokine profile of blood serum and there by increases the duration of the full clinical and laboratory remission in this category of patients.

A comparative analysis of step-drawdown tests was performed in order to estimate the well performance in Slovenian thermal and mineral water wells. Tests were performed in 30 wells, each having its own maximum production rate determined in the concession decrees. The main focus of well performance analysis, using graphical analysis of the Jacob approximate equation, was to estimate the adequacy of the wells production rate as well as to identify possible changes in the technical status of the wells over years. 5 of total 30 wells were not included in the analysis due to technical issues during test performance. Well performance analysis includes the calculation of nonlinear well losses related to turbulent flow and linear head loss (aquifer and well) assumed to be related to laminar flow. Results indicate that the ratios between nonlinear well losses and linear head (well and aquifer) losses, in this paper referred as laminar losses, are from 6.9 % to 97.4 %. Laminar losses parameter suggests, all investigated wells were classified with either good (11 wells), medium (7 wells) or poor (7 wells) performance. The addressed analysis represents a very important basis for further thermal and mineral water extraction, e.g. optimizing the maximum allowed production rate as granted in concession decrees and diagnose potential changes in the technical status of each well

The paper presents a way of selecting flat or carbonated mineral waters depending on the purpose for which it wishes to be used. A good mineral water must meet certain physical and chemical qualities at certain temperatures and have the appropriate pH to have the desired therapeutic effect. The analysis of the purpose for which the selection of mineral waters is desired results in the characteristics of the water to be analyzed, compared, and for which a weight of their influence in the decision-making is established. For selected waters, the characteristics receive scores that will in turn influence the selection of the recommended type of mineral water. The conclusions of the paper allow the establishment of a certain type of mineral water for the characteristics imposed by the desired purpose.

Lithium (Li) is an important micronutrient in human nutrition, although its exact molecular function as a potential essential trace element has not yet been fully elucidated. It has been previously shown that several mineral waters are rich and highly bioavailable sources of Li for human consumption. Nevertheless, little is known about the extent in which other beverages contribute to the dietary Li supply. To this end, the Li content of 160 different beverages comprising wine and beer, soft and energy drinks and tea and coffee infusions was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Furthermore, a feeding study in Drosophila melanogaster was conducted to test whether Li derived from selected beverages changes Li status in flies. In comparison to the average Li concentration in mineral waters (108 µg/L; reference value), the Li concentration in wine (11.6 ± 1.97 µg/L) and beer (8.5 ± 0.77 µg/L), soft and energy drinks (10.2 ± 2.95 µg/L), tea (2.8 ± 0.65 µg/L) and coffee (0.1 ± 0.02 µg/L) infusions was considerably lower. Only Li-rich mineral water (~1600 µg/L) significantly increased Li concentrations in male and female flies. Unlike mineral water, most wine and beer, soft and energy drink and tea and coffee samples were rather Li-poor food items and thus may only contribute to a moderate extent to the dietary Li supply. A novelty of this study is that it relates analytical Li concentrations in beverages to Li whole body retention in Drosophila melanogaster.

The objective of the present study was to determine the microbiological quality of bottled mineral water marketed in commercial establishments and by street vendors and to evaluate the influence of the storage and maintenance conditions on the microbiological quality of the product. Ten samples from the same batches of five different brands of water were analyzed, for a total of 50 samples. Of the five brands analyzed, only one (brand A), when collected in a commercial establishment, complied with the legal Brazilian standards for mineral water with respect to the presence of total coliforms, fecal coliforms, and Pseudomonas aeruginosa. The remaining samples failed to comply with these microbiological standards for at least one of the parameters evaluated. The water samples obtained from street vendors were inferior in microbiological quality to samples from the same batch that were obtained from commercial establishments.

ABSTRACT Bacterial growth occurs in noncarbonated natural mineral waters a few days after filling and storage at room temperature, a phenomenon known for more than 40 years. Using the full-cycle rRNA approach, we monitored the development of the planktonic bacterial community in a noncarbonated natural mineral water after bottling. Seven 16S rRNA gene libraries, comprising 108 clones in total, were constructed from water samples taken at various days after bottling and from two different bottle sizes. Sequence analyses identified 11 operational taxonomic units (OTUs), all but one affiliated with the betaproteobacterial order Burkholderiales (6 OTUs) or the class Alphaproteobacteria (4 OTUs). Fluorescence in situ hybridization (FISH) was applied in combination with DAPI (4′,6′-diamidino-2-phenylindole) staining, viability staining, and microscopic counting to quantitatively monitor changes in bacterial community composition. A growth curve similar to that of a bacterium grown in a batch culture was recorded. In contrast to the current perception that Gammaproteobacteria are the most important bacterial components of natural mineral water in bottles, Betaproteobacteria dominated the growing bacterial community and accounted for 80 to 98% of all bacteria detected by FISH in the late-exponential and stationary-growth phases. Using previously published and newly designed genus-specific probes, members of the betaproteobacterial genera Hydrogenophaga, Aquabacterium, and Polaromonas were found to constitute a significant proportion of the bacterial flora (21 to 86% of all bacteria detected by FISH). For the first time, key genera responsible for bacterial growth in a natural mineral water were identified by applying molecular cultivation-independent techniques.
