Determination of Biological Activity of Water Having a Different Isotope Ratio of Protium and Deuterium

Аннотация

Peculiarities of the vital activity of organisms at different concentrations of the D/H isotope ratio in water have been studied. It was established that many organisms react in different ways to both high and low concentrations of deuterium in water resulting in the reduction or enhancement of the activity of metabolic processes. However, the majority of test organisms have optimal indicators within the limits of natural D/H isotope ratio in water. The experiments with human cells in vitro revealed that the reduced deuterium concentrations significantly changed the vital activity indicators of cultures in deuterium-depleted water media. It was found out that not all taxonomic groups of organisms could be sensitive to changes of the D/H isotope ratio in water.
