EFFECT OF INTENSIFICATION OF SELENIUM-PROTECTION PROPERTIES IN LABORATORY ANIMALS DRINKING "FLINT" WATER DUE TO THE INCREASE IN THE COEFFICIENT OF DIFFUSION OF SELENIUM IN ORGANS AND TISSUESP. P. Olodovskiia and Yu. P. Istominb UDC 541.18:631.4 The influence of "flint" water on the development of biochemical processes which cause the accumulation of selenium in the body of laboratory animals has been studied experimentally. A decrease in the bond energy of the molecule of "flint" water with the anion SeO32- in relation to the bond energy of the molecule of ordinary water and an increase in the coefficient of diffusion of this anion in bone and muscular tissues in filtration of "flint" water have been substantiated. aCentral Scientific-Research Institute of Complex Water Management; bN.
