Project summaryAt present the interest in the potential adverse human health effects of extremely low frequency electromagnetic fields (LF EMF) and infrasound (IS), generating by a number of natural and artificial sources arises from health concerns. Because of more and more extensive use of LF EMF and IS in both civil life and for military purposes and the wide possibility to use LF EMF -and IS -induced modulation of biological effect of different physicochemical factors, which could serve as an instrument for international terror, the clarification of cellular and molecular mechanisms of biological effect of IS seams extremely important for adequate estimation of its biological effects on cell and organism, from the points of environmental protection and public health, as well as to decrease the risk of international terror. The weak knowledge on the mechanism of their biological effects on cell and organism is the main barrier for adequate estimation of their safety doses from the point of public health as well as for early detection of a number of natural and artificial catastrophes (earthquake, storm, tsunami, environmental terror attack and so on), preceded by the increases of background level of non-ionizing radiation. One of the most popular hypothesis on biological effect of non-ionizing radiation is “water hypothesis”, according which the cell bathing medium serves as the “primary” messenger through which the biological effects of non-ionizing radiation on the cells and organisms are realized. During the previous our works the frequency “window” (4Hz) of LF EMF and IS having the maximum effect on the changes of physicochemical properties of water and water solutions were discovered. The resemblance of superabsorbent hydrogels to living tissues and their ability to respond to an external stimulus by changes of gel hydration makes the latter as a unique model for studying the effect of ELF EMF and IS on physicochemical properties of the tissue, as well as for its application as extrasensitive sensors for detection of the changes of background environmental pollution by these waves. Therefore, the overall aim of the present project is to study the frequency- and intensity- dependent effects of LF EMF and IS on physicochemical properties (hydration, dielectric, optic and microscopic structure) of superabsorbent hydrogel at different levels of background radiation and temperature, and, on the basis of the obtained data, to synthesize a new superabsorbent hydrogel, having the maximum sensitivity to the changes of the level of background EMF- and IS –radiation. The newly synthesized superabsorbent hydrogel could be recommended as a sensor for detection of the environmental pollution level induced by such radiations. For these studies the modern conductometric, potentiometric, calorimetric, crioscopic, microscopic, x-ray diffractometric and THz-spectrometric methods would be used.
It is predicted that the data obtained in this project would allow us from one side, to understand the role of EMF and IS-induced changes of water–gel interaction in realization of biological effect of these factors on cell and organisms, and from another side- to obtained an extrasensitive sensor-hydrogel for detection of the changes of background radiation, which could be the signals for potential catastrophes or environmental terror attacks.
