We approached the elemental analysis of physico-chemical composition of some cold mineral water with CO2 which is therapeutically active properties in traditional medicine. In this study, we collected carbonic dioxide containing cold mineral waters such as Ulaanbaatar, Janchivlan, Uvur-Elgen, Zurt, Lam, Uvdug, Tsavchir 3 bulag, Khalzan-Uul in August 2018, and characterized on site and in laboratories for the volatile ion and physico-chemical parameters. The studied mineral waters were showed a total mineralization as 0.17-7.15 g/l, , and biological active ingredients such as CO2, Fe2+ and H4SiO4 determined as 0.21-1.3 g/l, 7.1-61.6 mg/l and 30.51-73.16 mg/l, respectively. The pH data of carbonic dioxide containing cold mineral waters were showed less acidic as 5.11 to 6.1. The oxidation-reduction potential (ORP) of Ulaanbaatar, Uvur Janchivlan, Lam and Khalza-Uul were ranged between -21 to – 78 mV with a highly reduction property which indicates potential biological activity rather than Ar Janchivlan, Uvur-Elgen, Zurt, Uvdug and Tsavchir 3 bulag which were ranged between 46 to 101 mV. The Ulaanbaatar, Ar Janchivlan, Uvur Janchivlan and Uvur-Elgen were HCO3- - Ca2+, Mg2+ type, and Zurt, Lam, Uvdug and Tsavchir 3 bulag belong to the HCO3- - Ca2+, Na+, Mg2+ type water. The Khalzan -Uul is alone belongs to the Cl-, HCO3- - Na+ type. However, ionic amounts are decraesed in studied mineral waters based on their chemical composition which are compared to the previously described materials.

We conducted the study of physico-chemical characteristics as hydrochemical composition and micro-elements in submineral water samples from Khuvsgul (WS1, WS2), Arkhangai (WS3-WS5), Khentii (WS6-WS11) and Dornogovi (WS12) provinces in 2017 and 2018. The pH data of submineral water in the Central part (WS1-WS5) were determined as 7.21 to 7.65, but in the East part (WS6-WS12) were showed less acidic as 5.68 to 7.86. The elec-trical conductivity (EC) and oxidation-reduction potential (ORP) in submineral water samples were ranged from 10.1 to 56.5 mS/m and -236 to 184 mV, respectively. Specifically, ORP in samples WS1, WS8 and WS10 were -236 mV, -22 mV and -56 mV, which are indicates the reducing property of samples. The hydrogeochemical results indicate that WS1-WS4 and WS6 submineral water are belong to the HCO3-Ca-Mg type, but WS5, WS7-WS10 and WS12 are belong to the HCO3-Ca-Mg-Na type water. The WS11 submineral water is alone belonging to the HCO3-Na-Ca type. Based on the geochemical compositions, the all studied submineral water were belong to the rock dominating area which were enriched by rock-water interaction. The radioactivity concentrations of 222Rn and its decay products 214Pb and 214Bi in samples WS11 and WS12 were 241-339 Bq/l and 307-315 Bq/l, 268-371 Bq/l, respectively. Thus, such submineral water is classifying to the radon-containing mineral water.

Currently in mass media and advertising we often hear about the importance of living water in human daily life. You may ask, “What is living water? Is it really living? Is it alkaline?” The importance of water to the human body can be determined by the oxidation – reduction potential (ORP) – a parameter characterizing the ability of the matter to give and connect electrons, which can be measured not only in water but also in food and in the air. Solutions, which contain negative ORP value (e.g. alkaline ionized water), are characterized by reduction features and have the ability to neutralize free radicals and stop the signs of aging. Solutions containing positive ORP value have oxidative properties, which are typical for the alkaline ionized water, which has bactericidal properties. Thus, the ionized water has two parameters: its pH and oxidation - reduction potential, which make it different from the ordinary water. Ionized water, like the raw unprocessed food, is considered to be the body rejuvenating agent. The basic principle, which should be followed, is to consume food and water, which contain the lowest possible negative ORP. The authors provide the research results, although, it is known that most of water tests are difficult to reproduce due to objective reasons, as water, with the gases dissolved in it, represents a very complicated balanced oxidation – reduction system. Oxidation reduction potentials of drinking and mineral water, as well as other beverages, have been studied, and the dynamics of these parameters in ionized water over time has been determined.

Abstract The purpose of the paper is to present original results concerning characterization of different sea buckthorn (Hippophae rhamnoides L.) extracts and some original dermato-cosmetic products containing these extracts. Aqueous distillate from fruits and leafy branches, aqueous extract from seeds, fresh fruit juice and frozen fruit juice after 2 years of storage, ethanolic extracts of buds have been analyzed for the following parameters: total and organic acidity, oxidability, calcium and magnezium, pH, conductivity, oxidation-reduction potential (ORP). The investigated sea buckthorn extracts have important contribution in care and treatment of skin diseases; during many years of experience in this field great benefits have been observed. Taking into account also the results of previous studies of other researchers we consider that the ORP measurement of cosmetic mixtures could provide objective, cheap and reliable information about antioxidant activity of complex samples.

Before And After

In previous communications on this subject (20, 21, 22) we described the results obtained when coloured indicators of known physico-chemical properties were injected into individual living cells. Using a modification of the micromanipulator of Chambers (4), we have worked with various unicellular protozoa and egg-cells, and have been able to draw definite conclusions as to the average hydrogen-ion concentration and the average oxidation-reduction potential of the cell interior. Our first communication dealt with the amœba, and we showed that its internal p H was probably in the neighbourhood of 7.6, while its internal r H (oxidation-reduction potential, 5) was between 17 and 19. Both values are near neutrality, so that this cell could be said to be slightly alkaline and slightly on the electronegative or reducing side of oxidation-reduction neutrality. We next extended our investigation to several types of marine egg-cells before and after fertilisation, and during the early cleavage stages. The changes which the internal p H and r H undergo during these ontogenetic events are very small indeed, and the phylogenetic differences, for example, as between the ovum of the polychsete worm and that of the starfish are correspondingly slight. The egg-cell, then, appeared to have a of about 6.6 and an r H of the order of 21 or 22. It was therefore a little on the acid side of acidbase neutrality and a little on the electropositive side of oxidation-reduction neutrality, differing on both these counts from the amœba. The amœba, therefore, has a higher intensity of reduction than the egg-cell.

Cavitation Action

The results of hydrodynamic treatment of water in the supercavitation mode are presented. Changes in the physicochemical properties of water (electrical conductivity, pH, oxidation-reduction potential (ORP), oxygen content (OCP), etc.) were revealed, the rational duration of cavitation treatment of water was established, and data on the relaxation of these properties were obtained. At the same time, there is an increase in temperature, pH and electrical conductivity, a decrease in ORP and CRC. The time range with the most intense changes in pH and ORP is 30–90 s. The rate of pH and ORP change in the range of 30–90 s is three and two times higher, respectively, than in the range of 90–300 s. These results correlate fairly well with the results of studies of the effect of ultrasound on water. It was found that the maximum pH value is reached under cavitation action for 180 s. The minimum value of ORP takes at 300 s of cavitation treatment, but remains in the area of positive values. It is shown that during the relaxation time, activated water after treatment for 200 min under the used modes of hydrodynamic cavitation treatment does not return to its original state in all measured parameters

Indirect Impacts

This paper presents the results of an experiment to simulate a sudden and brief hydrogen leak from a potential deep geological storage site. A 5 m3 volume of groundwater was extracted, saturated with hydrogen, and then reinjected into the aquifer. Saturating the water with hydrogen caused a decrease in the oxidation-reduction potential, the dissolved gas content (especially O2 and CO2), the electrical conductivity, and the concentration of alkaline earth bicarbonate ions and a slight increase in pH. These changes are observed until 20 m downstream of the injection well, while the more distant piezometers (from 30 to 60 m) are not significantly affected. During this experiment, no indicators of the development of chemical or biochemical reactions are observed, because of the rapid transfer of the dissolved hydrogen plume through the aquifer and its significant dilution beyond 10 m downstream of the injection well. Here, hydrogen behaved as a conservative element, reacting very slightly or not at all. However, this experiment demonstrates the existence of direct and indirect impacts of the presence of hydrogen in an aquifer. This experiment also highlights the need to adapt the monitoring of future underground hydrogen storage sites.

Hydrogeochemical Parameters

One of the hydrogeochemical parameters that classify groundwater as mineral water is the content of fluoride ions. Their concentration is both important and limited for bottled mineral waters. Hydrochemical research of mineral waters in the surrounding area of Bukulja and Brajkovac pluton, in central Serbia, was conducted in order to define the chemical composition and genesis of these waters. They are carbonated waters, with content of fluoride ranging from 0.2 up to 6.6 mg/L. Since hydrochemical analyses showed variations in the major water chemistry, it was obvious that, apart from hydrochemical research, some explorations of the structure of the regional terrain would be inevitable. For these purposes, some additional geological research was performed, creating an adequate basis for the interpretation of the genesis of these carbonated mineral waters. The results confirmed the significance of the application of hydrochemical methods in the research of mineral waters. The work tended to emphasize that ?technological treatment? for decreasing the concentration of fluoride in mineral waters occurs in nature, indicating the existence of natural defluoridization.
