Determination and assessment of healing properties based on chemical analysis of spring waters in Jizzakh (Uzbekistan)

. About 400 water samples were taken from the springs of Forish, Bakhmal, Zomin area and checked for organic matter, bromine, iodine, total mineralization, silicic acids, dissolved free carbon dioxide, total hardness. According to the results of the research, 60 springs met the requirements for healing water, that is, 9 springs with the required amount of total mineralization in the water, 1 spring rich in iron, 4 springs with bromine, and the iodine content is the highest. There was 1 spring, the number of springs rich in carbon dioxide dissolved in water was 26, and the number of springs rich in organic matter was 19. These chemical indicators are considered an important therapeutic factor in improving human health, in particular, peripheral nervous system, skin, gynecology, support and movement organs


Introduction
Jizzakh occupies an important place as an agrarian, industrial and manufacturing region of the Republic of Uzbekistan, as well as rich in natural resources.Districts of the region such as Bakhmal, Forish, Zomin, G`allaorol are also famous for their mountain and natural water resources -springs.Many of these springs have been worshiped and drunk by people for hundreds of years as healing.However, the composition of spring waters distributed in the territory of Jizzakh region, especially chemical, biological and physical aspects have not been systematically and thoroughly studied [1].The composition of spring water often changes under the influence of various factors (climatic, anthropogenic, and geographical) and also determines the properties of water [2].It is possible that the spring waters, which are considered to be healing and are being drunk by the population, have actually lost their healing properties [3].It is important to constantly evaluate spring waters based on consistent and deep scientific analysis [4] and check their impact on human health, because water is a natural factor that determines the health status of the human body while performing important and basic functions [5].
Spring waters with healing properties are a factor in the treatment of many diseases in the human body; in particular, they improve digestion, metabolism, gynecological, skin, and cardiovascular diseases [6].Balneological group mineral waters help with various processes in the body, in particular, iron deficiency, cell structure, growth and development, oxygen transport, increasing the amount of hemoglobin in the blood, respiratory tract catalyst, weight gain, proliferation of cells of internal organs (muscle tissue, liver, kidneys), plays a key role in stimulation of nitrogen metabolism, strengthening the body, skin, allergic reactions [7].A number of chemicals determine the healing mineral quality of spring water.These are the general level of mineralization of water (low, medium and high mineralization, hydro carbonate, sulfate, chloride), carbonic, ferruginous, bromine, siliceous, organic matter, boric, iodine, arsenic, radon, hydrogen sulfide, nitrogen-alkaline [8].These factors relevant for healing mineral water are different in the composition of spring waters, [9] one particular factor is present in one spring water, and several of these factors can be seen in the composition of other spring water [10].The same situation can be seen in the healing spring waters of Bakhmal, Zomin, Forish districts.The purpose of the research is to analyze the properties of healing springs related to human health.

Materials and methods
The research object covers three regions: Zomin, Bakhmal and Forish.There are many natural springs in these districts compared to all other districts of the region, and these areas include foothills and mountainous lands.The research was based on comparison, observation, and laboratory experiment.Samples were collected from three areas of the region and examined in hydrogeological organization of Hydrogeology.About 400 spring water samples were collected in specially cleaned and prepared containers (1 liter) for samples and were regularly and step by step chemically tested in the water laboratory.Samples were analyzed chemically, physically, and the indicators were analyzed by the program of Microsoft Excel.Total hardness, free carbon dioxide dissolved in water, bromine, silicic acids, iodine, total mineralization and amount of organic matter were determined, compared and studied by laboratory.

Results
Indicators such as organic matter, bromine, iodine, total mineralization, silicic acids, dissolved free carbon dioxide, total hardness of 400 spring water samples were analyzed, and factors corresponding to the standard requirements of healing mineral water were determined in 40 springs.The following table shows the characteristics (name, amount of the dominant factor) of the healing factor in spring waters and information about what diseases this characteristic can cure (Table 1).

Discussion
The standard requirements of the Republic of Uzbekistan for medicinal mineral (healing) water are a number of chemical composition of water, in particular, organic substances ("C" matter), radon, H 3 BO 3 , H 2 SiO 3 -+HSiO 3 -, iodine, bromine, total iron (Fe (Fe 2 + +Fe 3 + )), arsenic, total H 2 S (H 2 S+HS -), CO 2 , total mineralization are evaluated by the amount of the most important factors.According to the state standards of Uzbekistan, the total amount of mineralization for healing water should not be less than 1 g/l.The amount of total mineralization is different in the composition of the spring waters in the region, mainly showing low minerality (table 1).Qamishsoy VI (1.04 g/l), Qamishsoy IX (1.04 g/l), Jandaxor Ota (1.35 g/l), Qorobdol (1.01 g/l), Garasha (1.5 g/l), Tomtumsoy (1.36 g/l) in Forish district l), Tomtumsoy II (1.33 g/l), Suvlisoy (0.91) showed such amounts.We calculated Sho`rbulok (2.39 g/l) as having the highest mineralization rate in Zomin district and Jizzakh region.It is determined that the amount of total iron should not be less than 10 mg/l in accordance with the requirements of healing mineral spring water.Andigonsoy in Forish district showed the maximum indicator (11 mg/l).In accordance with the standard requirements of healing spring water, the amount of bromine in the water should not be less than 25 mg/l.Andigonsoy was considered to be the richest source of bromine with an amount of 110 mg/l.According to the requirement, the content of iodine in spring water should not be less than 5 mg/l.However in the Karamozor spring located in Zomin district, its amount was 4 mg/l.It was found that the amount of organic substances is the highest in the water sample of Yomchi spring located in Forish district (22.3 mg/l).The smallest indicator belongs to the Eshonlisoy spring and showed 5.2 mg/l.

Conclusion
400 samples of spring waters located in Zomin, Bakhmal, Forish districts of Jizzakh region were collected and tested, and 60 of them were proven to meet the requirements of healing mineral water.Farish has the most healing springs, 29 of the 60 springs examined belong to this region.In the second place is Bakhmal district, which has been proven to have 24 healing mineral springs.It turned out that Zomin has 7 healing mineral springs.5 of the springs with the highest total mineral content in the spring water are in Forish and 4 in Zomin district, one iron-rich spring in Forish, 4 bromine springs in Forish, 1 iodine-rich spring water in Zomin district, and one rich in carbon dioxide 24 of the springs were found in Bakhmal and 2 in Zomin district, and 19 springs rich in organic matter were found in Forish district.These results are the conclusions at the end of the research, and in the future, it is intended to continue the search for healing springs, scientific analysis and in-depth study in these areas.
