Kryuchenko N. Geochemistry of a drink waters of Ukraine

Object of researches - fluorine and its form of migration in drinking waters of different regions of Ukraine. The purpose of researches - to establish laws of distribution fluorine and its connections in natural waters, working scientific bases for creation forecast of maps ecology-geochemistry of risk of territories under the contents fluorine in natural waters. Methods of research - chemical, physical, физико-chemical (photometric, electrochemical potenchiometric, atom-absorption) and mathematical. The equipment - potenchiometr ЕПП-0,9 and magnetic mixing MM - 3, computer program PHREEQC. The results of work - law of distribution and the migrations fluorine in underground (drinking) waters have allowed to develop the practical recommendations for allocation of geochemical provinces with surplus or lack fluorine in territory of Ukraine and to give the practical recommendations concerning allocation and mapping of zones of ecological risk. Scientific novelty of the received results: 1) Features of distribution fluorine in drinking waters of the Lvov, Odessa and Poltava areas for the first time are revealed. 2) the basic geochemical conditions of formation sub-standard on fluorine of drinking waters in researched territories Are determined; the features of formation fluorine-bearing of waters in regions with different geological, geology-geochemistry, hydro-geological etc. conditions are characterized. 3) Are designed migration of the form fluorine for natural solutions of different structure, the connection between the contents of a fluorine-ion and other elements is established. 4) the main geochemical factors influencing occurrence endemic of disease Are established. Is proved, that at a rating of a degree of ecological risk it is expedient to use factor biogeochemistry of activity fluorine, which is defined by the attitude(relation) F- / MgF + + CaF +, or F- / sum Men Fmn-m. Sphere of application of results of work - geochemistry, medicine.
