ELEMENTAL COMPOSITION OF BIOLOGICAL WATER AS AN INDICATOR OF TECHNOGENESIS

Abstract

Technogenesis is a global process affecting all geospheric shells of the Earth. Indication of the impact of industrial facilities is carried out using a set of methods, including biogeochemical studies and monitoring. Their organization requires constant development and improvement of both technical means of analysis and methodological approaches; scientists of the entire world community are making efforts to search for new indicator objects that most adequately reflect the technological consequences for the environment and public health. Water can be used as such an indicator. Water has enormous ecological functions in general and special functions for a living organism, but, in spite of the significant role and long history of research, its chemical composition is poorly studied. 0,0003 % of Earth’s resources accounts for water referring to «biological water» by the definition of VI. Vernadsky. However, the change in its elemental composition is the most objective indicator of the technogenic transformation that occurs under the influence of various industrial objects. The works showing the background chemical composition of this resource are the basis for organization of monitoring research in the areas of intensive man-made pressure. The relevance of the study is determined by the lack of detailed study of a wide range of chemical elements in the composition of individual organs and tissues of living organisms, including the water in them. This substance reflects the chemical composition of environment and may be the subject to monitoring. The chemical proximity of the organism of the domestic pig to the human’s one allows obtaining a new tool for assessing the quality of the human places of residence, which directly assesses the body, which will significantly increase the objectivity of research. The aim of the work is to study the chemical composition of biological water of individual organs and tissues, on the example of domestic pigs, to obtain background characteristics for biogeochemical monitoring. The methods. Organs and tissues of seven-month domestic pig was sampled in Uspenka village, Pavlodar region (Kazakhstan) just after the slaughter and packed in plastics packages. Biological water was exudated by vacuum sublimation method upon the application of heat. The exudate was analyzed in certificated scientific-education center «Water» at Tomsk Polytechnic University by the method of inductively coupled plasma according to the certified HCAM 480X method with NeXION 300D spectrometer. Result. The authors have studied the composition and characteristics of distribution of 70 chemical elements in biological water, separated by vacuum sublimation from the organs and tissues of the domestic pig, selected on the territory of the conditionally environmentally friendly village Uspenka, Pavlodar region. The interrelation between the elemental composition of the biological fluid and the physiological functions of the organs of the animals studied as well as the composition of the habitat was revealed.
