FERRUTEROUS WATERS — the natural mineral waters containing gland (Fe ++ + Fe +++ ) not less than 20 mg/l used in the lechebnoprofilaktichesky purposes. are formed of the atmospheric waters leaching various rocks and minerals containing iron century. Depending on geological conditions with iron waters of very various ionic and gas structure and a mineralization, in particular the waters possessing acid reaction — carbonic and sulfate can be enriched. The general content of iron (generally protoxidic — Fe ++ ) can reach in. century of hundreds of milligrams on 1 l, in some groups — several grams on 1.
Allocate four most characteristic and widespread groups Zh. century, differing with structure, genesis, use in balneology.
1. Nitric low-mineralized (M< of 2 g/l) various ionic composition of water with the content of iron of 20 — 90 mg/l (Polyustrovskiye's water, the resort Marcial Waters, etc.).
2. Carbonic, low-mineralized, preferential hydrocarbonate waters, with a mineralization to 5 g/l and the content of iron of 20 — 60 mg/l (waters Baksan, Darasunsky, Kelechinsky, Kozhanovsky, Kukinsky, the Swallow, Tursh-Su, Shmakovsky, etc.).
3. The nitric sulphatic, acidic, polymetallic («vitriolic») waters which are formed in the oxidation zone of ore fields, sometimes with a high mineralization (to 100 g/l) in which iron-contains in very large numbers (to several grams on 1 l), it is frequent in combination with high ion concentrations of aluminum, copper, zinc and other metals (water Blyavinsky, Gaysky, Zubiysky, Karabash, etc.). In Italy waters of the resorts of Leviko and Ronchenyo, in GDR — waters of the resort of Lyusik concern to them.
4. Slabouglekislye (sometimes hydrosulphuric and carbonic), the sulphatic and sulfate-chloride, low-mineralized thermal, highly acid («fumarolny») waters which are formed in areas of a modern volcanism with very high content of ions of iron and aluminum — to 1 g/l and more (waters the Acid Key on the lake of Kunashir and many mineral waters of Kuril islands).
In the USSR. use century with to lay down. the purposes in the following resorts: Marcial Waters in Karelia, Darasun, Cook, Shivand in Transbaikalia, Shmakovka in Primorsky Krai, Guy in the Orenburg region; in balneolechebnitsa Dzhusalinskaya in Kazakhstan, the Acid Key on the lake of Kunashir, Polyustrovo where there is a plant of pouring, Kirovakan in Armenia, the Hop garden in Vinnytsia region.
Main balneol. value. consists in high ion concentration of active (bivalent) iron century, degree a cut is not identical in various listed above groups of waters. The only component defining to lay down. value of the first group Zh. century, the high content of iron is. Lech. value of waters of the second group depends on contents not only iron, but also and carbon dioxide; has balneol. value and general mineralization. Features to lay down. effects of waters of the third group are caused by high concentration of ions of iron in them and other metals. V Zh. century of the fourth group an effective agent are high ion concentrations of iron, aluminum, and also silnokisly reaction< (pH 5) and their natural termalnost. Existence in. century, except ions of iron as well other metals promotes strengthening of catalytic properties of iron. At contact with air a part of iron is oxidized and drops out in a deposit. To keep curative properties of iron and tastes of drinking. century, ways of the prevention of loss of iron in the form of a deposit, i.e. its transformations from a protoxidic form are developed (Fe ++ ) in oxide (Fe +++ ). There are various methods of deduction of iron in the dissolved state: rapid cooling of water, addition of harmless chemical substances, in particular seignette salt, sodium citrate, ascorbic to - you. Most efficiently saturation is considered. century carbon dioxide.
In a number of works it is shown that. century at reception them inside increase the general resistance of an organism, exert beneficial effect on motor and secretory (in particular, on bile secretion) functions of a digestive tract, promote improvement of appetite, increase in a hemoglobin content in blood. In an experiment the promoting effect of bathtubs is established from. century on the hemopoietic function of an organism. affect an organism with all complex of the chemical ingredients which are contained in them century. The issue of penetration of ions of iron through the unimpaired skin at reception of bathtubs is not resolved yet, however there is a number of the works showing a possibility of its penetration from artificial solution of salts of iron [V. V. Soldatov, 1970; J. Verne, 1935]. At the same time it is established that process of penetration depends on many reasons: pH of the environment, degree of a mineralization of water, ion concentration of iron in it and other conditions.
Indications for intake. Diseases went. - kish. path and gall bladder (hron, gastritis, peptic ulcer, coloenteritis, cholecystitis); iron deficiency anemia, and also urolithiasis and other diseases of a metabolism. At all these diseases use low-mineralized. century, generally first and second groups.
Indications for external use. In the form of bathtubs are used. century generally third and fourth groups. They are appointed at diseases of cardiovascular system (myocardial dystrophies of various etiology, a cardiosclerosis with a circulatory unefficiency it is not higher than I degree's, an idiopathic hypertensia of I and II degrees).
