Objective evaluation of the state of the environment may be made on the basis of the parameters of human health. The cities of Kirovsk, Apatity, and the Lovozersky district stand out among the cities and districts of the Murmansk Region for the diseases of the musculoskeletal system and urolithiasis. The population of these areas uses water formed within the giant alkaline massifs - Khibiny and Lovozero, containing the oxides of strontium, thorium, barium and rare earths. The solution - crystalline substance system was studied with the help of physicochemical modeling using the Selector software package. Environmental conditions and physiological parameters of the human organism were taken into account. Natural drinking water, gastric juice, a mixture of drinking waters and gastric juice were considered as the solution, while the newly formed phases in equilibrium with solution were considered as the crystalline substance. The chemical forms of the migration of elements including uranium were studied, and the conditions of mineral phase precipitation in the system natural waters - gastric juice under the conditions of reduced and increased acidity were investigated. It was demonstrated that the forms of element migration (Ni²⁺, Ba²⁺, Pb²⁺, Sr²⁺) remain carcinogenic or toxic at the temperature and parameters existing in the stomach. The proposed approach opens new opportunities in environmental and medical-ecological studies.
